8inch vw RK3188 wheelkey issue - Android Auto General

Hi there, i am not too sure if i need to start a new topic, but i guess this is the best way to get your expertise on my issue.
I am driving a seat leon 1p (2008) which had the RNS510 (seat media system so whitout the sd card slot) built in. Sadly the display died (full white) and i had to search for something else.
I bought me a RK3188 device (it says ERISIN in the advert, i cannot find that name on the box or device itself) with a load of nice features. Most of them are working like they should, others have some hickups and 1 is really bothering me. I have made a youtube video and the seller says they don't see whats wrong. I bought it trough eunavi on aliexpress.
Here my explanation, the leon is fitted with a large dot matrix mfd screen in the dashboard (boardcomputer) (there are versions with a smaller display)
the big display is served with the windscreen wiper handle, which has 3 buttons, up, down, and ok/reset.
When i want to reset my computer (trip, avg fuel etc.) i need to press the reset button about 3 seconds. the radio then decides to shutdown... once i release the reset button, the radio decides it doesnt want to shutdown.
Quite weird in my opinion. So i tried programming the wheelkey settings, according to the manual. first i go into wheelkey settings, then i press clear / reset.. then i need to press any wheelkey (so allso the volume up / down, next, previous etc etc.) the radio does respond to that, but not with the wheelkey settings programme. I'll try to add the youtube link here as well.
next to this, some weird things happen.
1.The display is way too bright, so i asked the seller what to do, they told me they will send a new display which i should fit myself. In my opinion not the best solution from a shop but i understand their marigins aren't enormous and they try to fix it cheap. the display hasn't arrived yet so i can't say if the new display gives the solution for me.
2. when i have the tuner on, with af-rds function, it seems to scan to any rds station once the signal gets weak. Maybe i'm spoiled, but i think AF needs to search for the station with the same ID as the one i was tuned in to.
3. the dab+ dongle and window antenna give poor reception now. this is presumeably caused by the way i fitted the aerial, on top of the ventilation shafts behind the dashboard. I want to move the antenna to behind the rear view mirror (horizontally) which will hopefully give good reception. (does anyone know if horizontal positioning of the antenna is okay for dab+ ?)
<- the issue with the MFD input
<- the whiteness of the display (cannot be edited with standard settings) it was quite cold when i made this video, it seems it is a little better now or i am getting used to it
so quite a long story and i have my fingers crossed on your response !
maybe good to let you know:

[Q] Issue with Navigation apps and power fluctuations

Hi, I'm pretty sure this is a unique or rare situation I've experienced, so I'm starting a new thread, but will endeavour to find similar issue threads.
On my motorcycle I have mounted a Brodit powered cradle for my Xperia Z. I figured it would be the ideal way of providing power to the phone while I travelled, and would allow me to use the phone as a Sat-Nav, utilising one of the many sat-nav apps (Google's offering, mapquest, copilot etc etc). Using the Brodit allows full use of the waterproof attribute of the phone - no socket ports need to be opened, and the phone doesn't need to be in a transparent case in inclement weather to prevent damage. I chose the Xperia Z (over other phones eg HTC) with this usage in mind.
It's worth nothing that I had a previous similar setup for my HTC Desire HD: without the powered mount, but using the charging socket and a transparent case over the phone for rainy days. It worked perfectly.
However - I currently am experiencing the following issues with the Xperia Z setup:
Firstly - The Brodit mount is 'not' weatherproof. (this is not Brodit's fault - it's not marketed as weatherproof) It provides power to the phone perfectly, until the first bit of rain, and then it starts to fail - either cutting out completely, or not providing enough current to keep the phone charged while the GPS / Mobile Data / Sat-Nav-App systems are turned on. (Previously it would provide enough power to increase the battery charge even while all the navigation systems were active). This is something I shall look into but I'm not really aggrieved about it - the cradle is NOT sold as an outdoor item so I'm not going to blame Brodit for this. I suspect that the issue is water getting into the 'spring-stud' connections and reducing the current flow. I'm going to see if I can adapt these connectors. If anyone has any further ideas or suggestions for better powered cradles too - I'd greatly appreciate it!
Secondly - and this is the main issue - when the power supply fluctuates (see above) the Sat-Nav Apps behave in a highly irritating manner : They instantly kill the viewport (it goes black), and also forget the current GPS location coordinates, and forget the viewport display setting: ie - show my current location in top down or perspective viewpoint and viewpoint relative to 'North'. When the power returns, the viewport, depending on how the app is being used, either returns to the start of the journey, or to a point in the journey where it remembers, but always loses the current location viewpoint settings.
This is obviously highly distracting, firstly you instantly lose your whereabouts which is dis-orienting, and secondly you then have to stop and reset all the settings so that the sat-nav display is back to doing what you want it to do. On a motorcycle this is further aggravated with the need to remove a glove in order to control the phone. On a recent trip to France I had this happen no less than 5 times in as many minutes right at the start of the journey.
It should be noted that I wasn't using the GoogleNav system in full directions mode. I find this mode misbehaves terribly if you're trying to use a customised route (see below for more info), and so I tend to load up my customised route so that it displays over the maptiles, and then I either just center my viewpoint on my location, or utilise the 'Preview' mode and again, center the viewpoint on my location (this mode displays a useful 'current direction of travel' arrow on your location).
Has anyone experienced issues like this, and if so - did you solve them? Or does anyone have any ideas for how to get into the configuration settings so that I can turn off the screen blanking and signal losses when the power fluctuates?
Thanks
Notes on Customised routes in Google Nav:
As I noted in this Google Product forums thread (just in case anyone else is involved) : https://productforums.google.com/d/msg/maps/DwPoT0pklas/sG0-sFYozT4J :
When in full 'Directions' mode, Google Maps a) doesn't poll your location accurately or often enough when slip-roads (off-ramps) are involved, and re-calculates the route to the next/final destination every time this happens - thus abandoning your carefully planned route.
So - I take it no-one has seen a similar issue or knows of a way to stop Google Maps losing all it's signals when the power is cut off?

Old Discussion about CarJoying RK3188 RK3066 2 Din Head Units (MTCB-Type)

Note from @dark alex:
Please note and know that Joying (Joyous) units are MTCB-Units and therefore discussions made here also apply to any other MTCB-Units and vice versa.
You are requested to participate and create discussions and Q&A-Threads instead of clearing things here because there is no difference except slight modifications in hardware design and the outer optics.

These all seem to be the same base model/design with the following options:
http://www.carjoying.com/2-din-car-gps-navigation/7-double-din-audio.html
JY-UQ124 = RK3188 Quad Core, 16 GB Flash, 1024*600 Screen
JY-UQ127 = RK3188 Quad Core, 16 GB Flash, 800*480 Screen
J-U1004 = RK3066 Dual Core, 8GB Flash, 1024*600 Screen.
J-U1011 = RK3066 Dual Core, 8GB Flash, 800*480 Screen.
They all have the same appearance. They have a 7" screen, with a single large knob (push for power), and a couple of buttons on the left side.

Here are some internal images.
The board seems to be a different, possibly newer design than what is shown in the HuiFei thread for the KGL/KLD models. The board does not have any silk screen printing identifying the components and the board is in a slightly different layout it seems.
Here is how it identifies itself on the android about screen:
This is the unit I have been looking at as I like the buttons for no look usage. Do you think it is good to buy it now or wait until they figure out Lolipop?
I chose this unit because it
a) didn't waste space with a DVD Slot which I would never use (come on its 2015 already), and so it had a full 7" screen
b) it HAS at least a volume knob. I don't like the new designs with all touch screen and no actual knobs or buttons. I just could not imagine using a touch slider for volume of the radio in the car. yuck.
c) I was impressed that carjoying.com actually seems to support their customers pretty well after the sale(in a very broken engrish sort of way but they are trying), that they actually answer questions very quickly (experienced a 1 day response to a question about upgrading personally), that they have a website where they have updates posted etc..
d) The price was pretty good. I spent $262 for the best model specs you can get, they have pretty good prices and fast free shipping via DHL Express from china.
As far as waiting for Android 5.. I don't know if its a big deal. Even if they don't there are going to be millions of devices out there that will be running 4.x for years and years.
You could wait of course, because we all know something better always comes along, but I figured for $250 it was worth it even if I replaced it in a few years with something better.
So far I am very impressed with this unit and its speed and functionality. All the Android Head Units are very very similar, all almost all run the same software, and have the same ports on the back, etc... it mostly comes down to the front panel button layouts, if you want a dvd slot on the front etc.. But other than the button layouts, any unit with the quad core RK3188, the 1024x600 screen, and 16GB Flash storage onboard will all be nearly the same between them all.
So frankly, I don't think there is really THAT much technical difference between the various brands out there. To me it comes down to price, and if I like the physical design/button layout of the device. And carjoying is the only one that I have found that has this particular front panel layout that I personally thought was the best design.

All of your points on why you chose this unit is exactly what I am concluding in why it would be great unit to buy. This is after spending a crap load of time on Amazon, Alibaba, Google etc. Just trying to make head and tails of all these different HU takes about a week as they list a lot of the exact same units at different prices but from what you can tell in the item description they have the exact same specs. Your bottom line of cpu, screen and storage is pretty much the best specs out there with a sorta "name brand" in Joying behind them.
I am looking to put this in an 2000 Audi S4 that is coming from a stock HU. Do you have an recommendations on the install? I know that Metra has most of the stuff I will need but this is the list I have so far:
2 Din Audi Frame
Wire harness
Converter
and maybe a AM/FM amplifier.
How long does it take for the unit to boot up? Is is basically AOSP or is there some sort of launcher that comes with it? Can I run Nova with it?
Thanks again for any information you can give
since one week i'm the happy user of this fantastical unit. RK3188 Quad core , 1024 x 600, 16 GB
Not mounted in car, for this time, next week, but i have upgraded 2 times firmware thank's Joying for your customers following.
Ultra responsive screen, excellent light quality and resolution, very ergonomic usage. It's the better unit i've never had....
Only a little regret, the cap over the SD cards slot seem fragile made with cheap plastic... and it's the only place where i have problem for insert or extract cards because need using a sort of needle for this, too small place.
But without these little default, it's the perfect unit for me...
Continue to support your customers by regular upgrades ( Lollipop ? )
THANKS JOYING

Interesting, is it in the future possible to update the cpu,memory and storage, if you take out the soc from the motherboard?

Yeah I have noticed the same thing. the door/cap is poorly designed. you kinda have to play with it to get it to close and go back flush again with the other buttons. I also that that is quite possibly my biggest issue so far with the unit.
I plan on just putting a 64GB SD card in there and leaving it, and transferring stuff via wifi onto it and never having to insert/remove it again. But, if you were planning on removing the microSD all the time I would guess it would not last very long before breaking.
If you want to do this sort of thing, I would recommend instead switching to a USB stick and plugging/unplugging it into one of the USB ports instead and leave the SD card(S) more or less permanently installed.
I did some power usage measurements on the bench today. I did the tests with a HP Agilent programmable power supply at 12V.
FULLY RUNNING: It uses about 1.2 Amps when it is fully up and running with bluetooth and wifi turned on.
SLEEPING: when the ACC power is turned off, it goes into a lower power mode and waits for the time (30sec-XXmins+) set in settings before fully shutting down. If the ACC is turned back on in that time, it comes instantly back on. In this state it pulls about 500 milliamps or so.
OFF: when fully off, it will draw about 4-5 milliamps from the battery which is quite low and makes me not worry about it draining the battery
I am just about ready to do the install into the vehicle. I did a few mods to the unit first.
Doing some testing on the bench proved that even though it seems to be a slightly different design, this unit also has the poor microphone audio quality of other HuiFei units when operating hands free bluetooth calling. There was quite a bit of noise/humming etc using the built in mic on the front panel. The external mic jack was a little better and had a little less noise but it still was not great. So I went ahead and did the mod everyone was doing to their HuiFei units to connect directly to the mic input on the bluetooth card.
On this unit, the board layout does not have a simple capacitor you can unsolder to disconnect it from the built in mic inputs. It seems to have a trace that goes from the bluetooth card directly to the front panel ribbon cable. I didn't want to trace it up onto that board so I decided to simply use a razor blade and cut the trace on the board (see picture below) which comes from the 4th pin on the bluetooth board connector (mic+). It looks messier than it really is because you have to first scrape through the solder mask etc. and it gets all scratched up in the process. I could see what I was doing better on the bench under magnification though so I know I did it correctly..
I then cut the existing mic cable plugged into the board and soldered it directly to the MIC+ and SGND pins on the bluetooth card.
I also decided to change the improvised wifi antenna which was on the unit that really was just a section of exposed coax, into being an actual RP-SMA jack on the back which I could then attach any wifi antenna. For now I used the antenna from an old wifi router I had in my junk box, I am actually considering adding an external wifi antenna on the outside of the car such as one of these. I imagine that would be a huge range booster.

Stock recovery
Hello everyone.
I have the RK3066 wich i installed twrp on cuz i though i had to use it to be able to flash roms but that is not the case. now i wanna flash the original firmware back but i didnt save it before.
can anyone save the stock recovery and upload it please ? it can be done with flashify app on the play store
you just need to root the device ( o to Settings->Factory Settings, and enter *#hct#root# as the password, it enables root on the device ), then install flashify and choose backup recovery
thanks in advance, i really need it

Your pics aren't working for me
It ended up cutting the pin that goes from module to board
But the trace you're referring to doesn't actually go to that ribbon cable closest to the module.
It actually runs across the front (infront of the ribbon cables) then over to the external mic plug somewhere over there

Hey @nixfu. Still unable to see the pictures.
I am really interested in checking them out.
Thanks for taking the time to post them.
i own this unit, close to perfect
i bought this one from Germany to speed up delivery and avoid taxes (it takes 3 days to arrive to me in France):
joying-europe-eu-warehouse-2015-latest-aftermarket-7-inch-2-double-din-1024-600-in-dash-car-stereo-android-4-4-4-kitkat-quad-core-head-unit-autoradio-16-gb-memory-touch-screen-airplay-gps-navigation-radio-audio-system-support
I chose this one because of
- 7 inch
- 4 core RK3188
- Android 4.4 and future 5
- Physical buttons
- ISO provided
- very regularly firmware releases
- more powerful model for a veru correct price to compare to major brands of market
- The technician/vendor Rambo is very communicative/avalaible, even after buying
It replaces a Parrot smart, which is a very good unit too but stayed at android 2.2
I approve all previous comments on this unit, very high end finished except plastic cache of micro-SD cards which looks cheap.
Unit starts in 15 seconds, good suprise. Interface is very reactive and i can install what i want. Sound is good and radio reception too.
My concerns are:
- no tethering bluetooth 4G sharing with my mobile phone, only wifi hotspot works. It's a pitty because it drains battery of my phone.
- no vocal command for calling, searching music
- only GPS app could be changed as default, no music app neither radio app
- it's not very easy to tap on the letters located in the border because of the physical extended frame in high
- no favorites feature for radio channels
I have read that i can deblock some thing with a rooted firm, xposed frameword and mode MTCxposed. I have to check it out.
Anyway, quality/price surpasses theses concerns to me and i am very happy with this buy.
i would like to buy the Model JY-UQ124 = RK3188 Quad Core, 16 GB Flash, 1024*600 Screen,the Specs looks good!
I have now a AN-21U in my Car installd with the newest Redmod but the Boottime and the Mic Gain sucks!
-how long does the boottime from the Carjoing model take and how is the quality of the Microphone?
-I read something about a Mic Mod, which is in the model also necessary and if so, there is a manual for the Mic Mod?
-can I use the Malaysk Rom for the Radio?
Is it worth it to change the model at all?
thx

Hello,
i have same model and like i wrote in my previous post, it takes 15s to boot.
Ext Mic quality is good (don't test internal mic). I put it in front of mine and can dial without concern. My interlocutors don't complain.

Proper Android Auto headunits

Have just returned my Xtrons unit due to various issues, and looking to change it for a proper Android Auto unit.
Had a look at the Pioneer AVH-X8700BT and quite disappointed, horrible buttons and a creaky flexy facia, and the onscreen menus etc are cluttered and unintuitive. This is a shame as I could have got 20%/£100 off in Halfords.
So interested to hear from anyone who has tried the others. I keep seeing comments about a JBL unit but it seems the launch date keeps getting shoved back. Kenwood - I've not found much about these but not hugely impressed by the look of the on screen menus in the static photos.
The one that has really got my attention is the Sony XAV-AX100 that has supposedly just been released. The unit looks smart and doesn't appear to need neon footwell lamps and extra boost gauges to complement it, (!) and the Sony menus have similar clean/uncluttered look like the Android Auto section. Apparently its only available via Sony Centres and both my local stores haven't come back yet with availability
I agree with your analysis of the options but i don't think the Sony product is released until December:
https://www.amazon.co.uk/exec/obidos/ASIN/B01LY8222N/geizhals07-21/ref=nosim?m=A3P5ROKL5A1OLE
I personally got the Pioneer F88DAB (which is a european model) and I like the way it works. the menu is working quite well and I like the fact that I am able to adjust the screen tilt.
Android Auto works great at the device and I will upload a video of the device with android auto, so you can see how the menu and all the functions look like.
amazon
that JBL has been pushed back so many times, I would not have any faith in it. The top of the line Kenwood is over a grand, but I have seen some really good reviews on it and few bad reviews. That was my backup plan if I didn't like my Joying, but I love my Joying

At £850, it's poor value - you could professionally install a tablet for a lot less. I think I'll wait for the Sony for x-mas

That is true, but it was easier to install and I personally like the interface of it.
The Sony is a good choice. With a pioneer device you can use appradio or mirra cast.
When I am home, I will upload a video on how it is usable.

I have the previous model the Pioneer F77 DAB. Works very well. Back in the day halfords had it for something over £800 then by accident halfords listed at £600 so reserved one sharpish. Couple of days later it was back at its original price. I think someone had cocked up.
Far as android auto is concerned it works faultlessly. It's pretty quick booting up from off and reverse camera works straight away, not having to wait for unit to boot. Occasionally when turning vehicle key to on unit comes on as normal but if you then hesitate to start engine it seems to crash and take maybe a minute to boot again. Even reverse camera does not work when this happens. Unit comes on when key is turned to power but cranking engine robs power from unit so it turns off and on again. The crash is something to do with the stage of boot when power drops. In all the time I've had it, it has only happened maybe half a dozen times. Other than this it works faultlessly. Pioneer want stupid money for mapping updates for the built in satnav on the downside but half the time I use Google maps in AA for quickness. Pioneer has an app to connect the phone to on board sat navigation - AVICSYNC. It works but is very clunky. Waiting for Waze to become AA compatible but not holding my breath on that one.
Well after failing miserably with two local Sony centres and also Sony online, I managed to find the unit for sale on Amazon! I'd set my heart on it and after three months with a gaping hole in the dashboard, its finally fitted!
First of all, its single DIN behind the facia so plenty of room for wiring looms, and simply slides in unlike the Android units that would need 30 minutes of trying to pull the cables around and still failing to get the facia flush. Also, as expected, it comes with a cage and standard mounting brackets so no bodging needed. Once fitted the unit sits neatly within the existing double din facia.
It starts up fast, works with my factory fitted reversing camera (unlike the Android units) and is simple to navigate. I was concerned about the 'cheap' resistive screen, but its actually very responsive and only needs a light touch.
The only issues I have so far;
1) The volume control knob needs a fair bit of spinning, it needs two or three goes to crank the volume down. I need to check the settings again to see if you can make the adjustment less fine.
2) If I connect the phone and play music on Spotify, and then start the engine, the unit powers down as normal during engine start. When it resumes, the music starts playing on the phone...I have to swipe across to a second screen and press a '+' speaker button to get the audio back through the vehicle speakers. A bug with my phone, or the radio? Something to look in to.

Thats fine, although really irritating if your passenger is trying to find some tunes. But it does the same when stationary...I'm sure my handbrake is wired correctly but regardless, I'll be over-riding that feature as its in a campervan and I normally have a passenger!
4) Just to answer my own questions about the unit; No, the facia is not removable. No, it doesn't come with a remote control (a shame for a campervan!) And unlike the Android units, everything works seamlessly. i.e it doesn't freeze or get laggy, you don't need to wait ages for the unit to boot or Google Maps to load, and if you start the radio, Spotify etc will stop, rather than having two lots of audio competing for your attention

Android Auto uses the phones GPS and maybe accelerometer to know when you've stopped.
On my Kenwood unit the handbrake sensor is grounded all the time and I still get that message.

Well after failing miserably with two local Sony centres and also Sony online, I managed to find the unit for sale on Amazon! I'd set my heart on it and after three months with a gaping hole in the dashboard, its finally fitted!
First of all, its single DIN behind the facia so plenty of room for wiring looms, and simply slides in unlike the Android units that would need 30 minutes of trying to pull the cables around and still failing to get the facia flush. Also, as expected, it comes with a cage and standard mounting brackets so no bodging needed. Once fitted the unit sits neatly within the existing double din facia.
It starts up fast, works with my factory fitted reversing camera (unlike the Android units) and is simple to navigate. I was concerned about the 'cheap' resistive screen, but its actually very responsive and only needs a light touch.
The only issues I have so far;
1) The volume control knob needs a fair bit of spinning, it needs two or three goes to crank the volume down. I need to check the settings again to see if you can make the adjustment less fine.
2) If I connect the phone and play music on Spotify, and then start the engine, the unit powers down as normal during engine start. When it resumes, the music starts playing on the phone...I have to swipe across to a second screen and press a '+' speaker button to get the audio back through the vehicle speakers. A bug with my phone, or the radio? Something to look in to.

Re "And unlike the Android units, everything works seamlessly", not true - please see your points 1 and 2 !!
Re "unlike the Android units . . . it doesn't freeze or get laggy, you don't need to wait ages for the unit to boot or Google Maps to load", Android units per se dont have this problem, one particular type, with only 1GB RAM, Lollipop and a later version of Google Maps does, this can easily be sorted.
Glad youre happy with your new unit, enjoy.

My unit came with a remote. I also find what I believe is a software bug, if you turn on the dimmer the maps will always be in night mode.

I've got the same issue. As of 2.0 Android Auto uses the head units' GPS data. If your head unit doesn't have built in navigation (GPS), it won't remove the limitation even if stationary.

I found out it's by design by reading the user manual a bit better. The dimmer is connected to the headlights and when you turn on the lights it will go into night mode, unfortunately I use the lights 24/7 so I will install a toggle switch instead to turn on/off the daylight and the night mode. Pioneer has a a similar setting using the headlights but they also have a setting where you can set the time for night mode, hopefully Sony will have something similar in a future update.
Thanks for the replies!
I've worked out that the unit is detecting the handbrake as the video playback from an SD card is interrupted. I see the comment about the Sony not having built in GPS causing Android Auto to keep the 6 press limit, thats annoying, lets hope its fixed in an update. Surely it can use my phones GPS signal to work out when I'm stopped!
Terre08, I'll send you a PM regarding your remote...interesting!

Datalogging for a Kart

Hello everyone. I am Mihai from Romania.
I want to start a project using Raspberry Pi 3 (maybe connected to an Arduino) to log data from my GoKart and display it on a 5" touchscreen.
I was wondering what hardware do I need? (I am asking because I don't have the money to buy and try)
I want to: log and display the position of the accelerator and brake pedals (could use a rotary potentiometer attached to the pivoting poind of the peddal maybe?), log and display RPM (was thinking something attached to my spark plug wire - very high current passing through that wire), log and display G-force, log and display speed (maybe a sensor at one of the wheels or GPS), display the gear I am in (this is already done using two buttons).
And maybe after I get all this done, I would like to build/code a GPS lap-timer using the same equipment (to display the time/lap on the screen).
Like I said, I have already build the gear indicator and a system that changes gears when I press two buttons (for up and down shifts).
All this has to be powered by a battery since I will be racing the kart around the track.
The data has to be displayed on the screen in real time.
I am happy to provide any other details you might need.
Any help is appreciated. Thank you very much in advance.
Any help would be apreciated.
Maybe if you know what would be best for only one input. Foe example, what would be best to log the position of the peddals? Or just what to use to record rpm.
Thank you.

Red Tint on Nubia Red Magic 3

Just bought a global version of the nubia red magic 3 and the display has a red tint like the ones on Samsung S8.. It got worse as it was emphasised when I turned on the night light:crying:

Yeah mine isn't bad unless I turn brightness below 20%...the CN Rom has display color adjustments, apparently they deemed this non-exclusive to Global Rom.

Well if it's too bad and you bought from Red Magic Store you do have 12 month warranty. But updates would be nice for sure.

Indeed, literally I circumvent it by turning off Adaptive brightness and leave it on 50%, the game launcher has brightness control built in too so that helps. If you want gestures, I can recommend "Fluid NG" in the playstore, then run the adb command to hide stock navigation and you can turn it off and on when you want. The CN Rom truly is great but the SMS system is not good in US with their WeChat or whatever it's called lol. Plus LTE won't work you can only get 4g on CN.

RM3, 8/128GB, Red, NA variant.
Just got the phone. First impressions here first. I'll probably write a full review with pictures in a separate thread.
There's no particular order of importance of these following points.
1) The phone is gorgeous - it's a stunner. Also, huge. Makes my old OP6 look small. Side note: there's only swiping down from notification portion of the screen - meaning that you have to reach to the very top with the first swipe. But overall one-handed operation is not that much different from OP6 - in other words, tough.
2) Less slippery than all glass OP6. Feels really good holding it.
3) The display quality is on par with OP6. Not quite as picturesque as a GS9 display, but very nice looking. Haven't tested it in full sunlight yet. Also, the display is huge. Literally feels much bigger than OP6. The bezels are noticeable, but are definitely not a problem because most apps hide them.
4) Display 90Hz - you notice it right away and then you forget about it. But when I went to OP6 (the fastest phone I've used before,) it felt a bit choppy. 90Hz is real. Also, the phone itself feels significantly faster than OP6 - boot up, how quickly widgets update after a reboot, etc.
5) The battery is... fantastic - I'm so far projecting about 11 hours SOT.
6) The camera is MEH. I'll have to test it more, but so far it looks like a weaker version of OP6, which was already meh. I'm sure it's gonna provide excellent pictures in good light (haven't tried), but in low light - not so good. For example, 48mp mode is completely useless in low light. You have to switch to 12mp to get a decent shot (it combines 4 pixels into one to get more light.) I tried a few Google Cam apks, but haven't found one that worked.
7) There are bugs:
a) My sim card won't allow to set up call forwarding with AT&T. It works fine with OP6. Gonna get a new sim card tomorrow.
b) Swype keyboard (old apk) just doesn't stick. I tried like a million of different ones, none stick - phone always reverts to GBoard. Maybe it's an Android Pie issue. Very annoying.
c) Chromecast and Smart TV work perfectly except for one thing - screen mirroring doesn't work with Chromecast. You can stream, cast, mirror with TV etc, but that one single thing just doesn't work - it says Connecting...
Overall, I'm very happy with the phone, provides I can resolve some of the issues above.
Just bought the eco-sport case... It's worth the price, but if you are planning to use or buy the controller, just by the the case suitable to it...
UPDATE on the Red one:
1) Chromecast now works with screen mirroring just fine - must have needed to be rebooted.
2) I think the issue with the sim card and not being able to configure call forwarding is almost clear now - the card reports the Slot 1 IMEI as CDMA (14 digits). But even the Slot 2 IMEI (15 digits) gives an error "Network or Sim Card error." Called ATT and they recommended a new sim card, free of charge. When I get a new sim card tomorrow I will report back.
3) I have a serious issue with either the phone or the power button position. My phone rebooted 3 times in 5 minutes today. It may have been me inadvertently pressing the power button w/o realizing it. It it may be a defective phone. I rebooted the phone, cleared cache in recovery, and there were no more problems. However, the power button is in a perfect position for my thumbs, both hands, to press that button without realizing it. Maybe I'm holding it wrong.
UPDATE #2:
1) I'm still struggling with some issues but I am also getting some resolved. The power button thing came back once - I still cannot tell what the problem is.
2) On the bright side - this camera is amazing in bright light and medium light conditions.
I took some photos in good and dim lights. The results were spectacular.
Example - a room was illuminated by a single weak lamp and a distant window full of sunlight. The 12mp picture was as good if not better than a Galaxy S9 picture.
This was significantly better than OP6.
I think if someone made a Google Cam port for this camera, it would be flagship level quality.
Guys, FYI, some of our questions might be answered through this link: https://bbs.nubia.cn/thread-1472848-1-1.html
[The system of XDA won't allow me to share this as a new thread so I'll just post this a reply]
It's in Mandarin but google will translate the texts..
For those who worry about the security of the thread, here are its contents:
(P.S. They refer to the Red Magic 3 as Red Devil 3)
Since the launch of the Red Devils 3, due to its strong performance, super heat dissipation, cool appearance, and long-lasting battery life, it has attracted many magic beans to place orders at the first time. The first 90Hz screen, 4D shock and five-finger control are well received.
After the listing of the Red Devils 3, we also received feedback from some enthusiastic magic beans, and compiled this quick question for some of the more feedback problems, hoping to help everyone get started smoothly~
PS: It is expected that a new version will be pushed at the end of May (actually likely to be advanced) to focus on some of the more feedbacks.
Please have the magic beans in need to leave IMEI in this questionnaire, we will give priority to push. Https://wj.qq.com/s2/3664012/b082/
Red Devils 3 Q & A APP Banner.jpg
1, the screen has a distinct graininess, the resolution is not so high. It doesn't look too delicate, can you feel the granularity?
A: Previously, on some models, to save memory usage, the resolution of the built-in wallpaper was reduced.
Subsequent we will increase the resolution of our own wallpaper. Please download the HD wallpaper yourself to experience the clarity of the screen.
2, the screen color is a bit rich, the color temperature is a bit yellow when the eye protection mode is not opened, is it yellower than the first generation?
A: The Red Devil 3 is an AMOLED material, which is more beautiful than the LCD display. It is a normal phenomenon.
Regarding the color temperature, the factory is adjusted according to the style of the public, and also supports customization.
You can go to the Settings - Display - Screen Color Display and adjust to your favorite color temperature on the palette according to your own habits.
3. I feel that the top speaker sound is smaller than the bottom sound speaker. It sounds like no texture, no bass effect?
A: In order to give users a better gaming experience, the Red Devils 3 uses a dual-speaker and dual-tone intelligent power amplifier solution to increase the volume.
In the audio design, in order to ensure the balance of volume and tone, the upper speaker is mainly used to output the medium-high frequency band. The lower speaker outputs a full-band solution for an excellent listening experience.
In the actual experience, the external stereo is very obvious, please feel free to use.
4, my mobile phone protective film is smashed, watching how some bubbles are going on?
A: I am very sorry to bring you a bad experience. Please call the after-sales customer service 400-700-6600 for this question. For the flaw on the film, we will give you a new film for free.
5, sometimes the phone will automatically restart, how is this going?
A: We have located the reason and will resolve this issue in the next release, please update to the latest version to experience.
6, playing games sometimes encounter breaks?
A: The new version has been optimized for touch. Please update to the latest version after V2.14 and later. We will continue to follow this feedback in the future.
7, a key change machine connection timeout, Sony mobile phones and Xiaomi 8 can not connect.
A: Please upgrade your phone to the latest version first. We will also perform internal verification simultaneously, and will fix it as soon as possible if it is confirmed that there is a problem. If the new version is still not resolved, you can contact the after-sales service for testing.
8. Feel that the right side of the capacitor button is not sensitive.
A: Since the scene of the right capacitor button was found to be inadvertently touched during the test, some adjustments were made later.
We have feedback optimization for such issues. If it is more influential, please contact the after-sales service for testing.
9, playing the king's glory encounters the problem of crashing and crashing.
A: Please update your mobile phone to the latest version and experience it. If there is still a recurrence, you can contact the after-sales service.
10. Can't connect to WiFi? It will not work after restarting and restoring the factory settings.
A: Since Android 9.0 has improved security permissions, the switch to add a hidden network is turned off by default.
To add a hidden network, open Settings - WLAN, slide to the bottom, click "Add Network", then click "Hide Network", select "Yes", and then enter the name of the hotspot you want to add to add it.
If the WiFi network that is normally displayed directly cannot be connected, please provide the brand and model of the router. We will transfer it to R&D for analysis, and we suggest that you contact the after-sales detection process directly.
11. The fever is a bit big when playing games.
A: Turning on the "Red Devils Time" will result in a slight increase in power consumption and heat. You can try to close it first. The specific path is: enter the game space, click on the avatar in the upper right corner, click on “Time Setting”, and click on the first item “Red Devil Time” to close. At the same time, click “fan adjustment” to turn on the cooling fan and adjust the fan speed to “quick cooling”.
12. The triangle on the right side of the back cover logo light is found to be out of color, and the top left of the camera is also. I thought it was the oil on my hand. I cleaned it with a wet tissue and found it to fade.
Answer: The logo on the back cover LOGO lamp and the camera is laser engraved, which belongs to physical etching. In theory, it will not “color fade”. This may be caused by dirt on the surface. Please wipe it with a dry cloth or a corner of the clothes to return to normal.
13, using Huawei, Xiaomi and other friends charger and data cable can not be charged, unplug the charger still shows charging?
A: Since the chargers and data lines of different manufacturers have their own optimization and limitations, it is recommended to charge the mobile phone only with the original standard charger and data cable.
14, stimulating the battlefield game is prone to the right perspective can not move?
A: This problem is generally caused by the position of the palm of the right hand pressing to the edge of the screen when the horizontal screen is held, causing the finger to move. It is recommended to adjust the holding posture appropriately. Subsequent versions will also be optimized for such scenarios.
15. After setting the screen refresh rate to 90FPS in the game space, is there a feeling of spurring the battlefield?
A: At present, only some games support the 90FPS refresh rate. Since the stimulus battlefield does not support 90FPS display temporarily, it is recommended to set the screen refresh rate to 60FPS or “Auto”. The recommended setting is “Auto”, and the game works better when the game settings match the screen refresh rate.
16. What is the effective rate of the 240Hz touch screen reporting rate?
A: Add the app to the game space application list. The application in the game space list can support the 240Hz touch screen report rate regardless of whether it is open in the game space.
17. When the hands are held horizontally (especially in the game state), the WiFi signal is affected?
A: The Red Devils esports game phone uses a dual antenna design. The WiFi antenna is located on both sides of the top of the phone. It is recommended that you do not hold the top of the phone with your palm when playing games or watching movies on the horizontal screen. Use your fingers to support your phone to prevent the phone's wifi signal from being blocked.
18. Will the fan get into the water and get into the ash?
A: The fan body can achieve IP55 waterproof and dustproof, and all of them have passed relevant tests. Please feel free to use them. It is recommended that you use them with care to avoid any troubles to your experience.
19. Can't connect to the computer?
A: The latest bidirectional Type-C data cable is included in the package, not the traditional data cable with USB interface.
If your computer is relatively new, with a Type-C interface (smaller, similar to the charging interface on the bottom of the phone), the original data cable included in the package can be directly connected.
If your computer comes with a normal USB interface (traditional, larger USB interface), use a traditional Type-C data cable with a USB interface. In most cases, the data cable can be used universally.
But be careful not to use the Huawei brand data cable, you may encounter compatibility issues.
After plugging in the computer, you need to unlock the phone first, and click the top line from the drop-down status bar to say "Android system is charging this device via USB", click on the menu, and then select "Transfer File", then you can get from the computer. I saw the connection information. If you still have problems, please contact the after-sales detection process.
20, the system is too inhuman, and add some daily application functions. WeChat Alipay payment code sweep, shortcut keys to open flashlights and so on.
A: The above said that there is already, please pull down the notification bar, swipe to the right, click "+", which is "custom".
Go to the bottom of the page to list more switches, click to add the switch you need, long press the added switch, you can freely adjust the position of the shortcut switch.
Everyone has other questions, welcome to post ~
Of course, in the process of using, when you find fresh and fun and interesting features, you are also welcome to send out, sharing is a pleasure, but also the motivation for us to persist in innovation and make good products, and continue to advance!
