Using 2G data on z3c - Xperia Z3 Compact Q&A, Help & Troubleshooting

I'm still using stock 5.1.1 ROM, because I'm not clear whether I lose some functionality by rooting / unlocking the bootloader.
I like to use my phone in 2G data mode, that feels safer on my body than 3G and above - but this device considers 2G only mode to be calls and text only (i.e. data off!).... this seems crazy to me since data off is achieved more easily with the option just for that. Is there any way to have proper 2G data only mode?
So when I go into the data options I get the usual set of things, and 2G says "2G (voice and calls only)", then when I switch to this, data is actually turned off. When try to turn data on, I get a message saying I've got to switch data mode to be able to do this - data stays off until I choose "3G (preferred) / 2G". It seems like the software on my device is designed to turn data off when you choose 2G - very odd.
No updates are available when I check. I'd love to go to marshmallow, but I guess I've missed that until Sony release their tested version of it - that update might fix this issue.
Missing my rooted Samsung Galaxy S3 already! - recently bought second hand device.
Many thanks, Geoff

For me this used to work on kitkat (i can't remember on lollipop because i use concept 6.0.1):
in quick settings i'd turn off LTE and then in settings - mobile networks i'd set to 2G only. And afterwards by switching LTE on and off form quick settings phone would toggle from 2G and LTE. But since i didn't pay for 4G to my provider, my phone would toggle from 2G to 3G - just what i wanted.
I used to use 2G on my old Xperia P since it improved my battery life dramatically. I continued to use it on my Z3c while on kitkat, but it didn't affect my battery life so i stopped - hence I don't know if you can do this trick on lollipop.
Goog luck and I hope this helps.

I don't really understand you... I'm using 5.1.1 and if I switch to GSM only, ALL network stuff is using 2G - calls, texts, mobile data (little E letter right next to the signal icon). So... what's really a problem? Maybe I don't understand the context (I am not a fluent english speaker but I understand it pretty well) but please describe your problem more precisely
P.S.:
Rooting doesn't harm your device, your camera resolution won't change at all so don't worry
[Unlocking bootloader DOES harm your device (losing some DRM-related stuff) but there are plenty of other benefits from this AND you can revert the DRM changes.]

Wait, what ?
Are you seriously thinking that 3G(HSDPA) or 4G(LTE) is somehow more harmful to your body ?
That's ridiculous. The power levels used in 2G and 3G and 4G are all roughly the same and always below 250mW.

yes from discussion and reading research I feel there's a case for being cautious, that we've not had enough time to adjust to this technology - see for example http://forum.xda-developers.com/showthread.php?t=473209

Better start wearing tinfoil hats m8
(That's so esoteric I won't even bother responding. The power levels used are not even remotely high enough to cause cellular changes)

thanks for your message - I think you understand well, but your phone is giving different behaviour. I've added more description, in case that helps anyone

like I said, we each choose - and choose how much we look into it. Probably similar comments from people in the 60s to anyone questioning Aspestos. It's easy for either of us to generalise that it's OK or not, with examples from the past, but there's information out there that's looked into this and is thorough, including significant instances of phone engineers with brain tumors. We don't agree, let’s at least be respectful.

1) When 2G is working on 1800 MHz band (this happens especially if you live in a big city), the energy is more or less the same used by 3G technology.
Anyway this is not the point.
2) Are you sure your network operator has 2G data connection available? Is your firmware branded?
You don't lose DRM keys while you flash an unbranded firmware or you root the device with giefroot method.
Have a look at the general section

thanks for your reply - yes definitely there's a 2G connection, as I live in the countryside I end up on this quite a bit of the time, when in "3G/2G" mode.
I'm on a UK network called Tesco that uses the O2 network. Phone originally came from O2 (telefonica), but is now SIM unlocked. Behaviour was the same before and after unlock - no surprise as software the same. Build number is 23.4.A.1.264, kernel 3.4.0-perf-gbe52486 (September 17 2015)

Threads like the one you linked and statements like above just reek of not understanding how GSM and 2G/3G/4G actually works.
Stuff like
As 2G and 3G have different requirements, they also have different power consumption. It doesn't require much more than common logic to understand that since 3G needs to transfer more data during a short period of time, it would use more resources than 2G, which needs less during the same period.

Is just wrong. It's all about modulation. MATH basically.

Cannot make calls while on 3g. Tmob advised me to switch to GSM as the solution!!

grrr
what a **** workaround!
that was their response... a **** workaorund that degrades my service..
anyone else had this or any thoughts on it?
Don't switch to GSM, switch to AT&T!
I am not a fan-boy for any of the carriers, but I must say that over the years I have gotten excellent service from ATT - except for when they changed to Cingular, which was a collection of regional companies with regional problems and inability to service - IMHO - a truly mobile client (like I live on the East Coast, but kept a west coast cell number - Cingular couldn't understand or deal with that one)...and the coverage is now better than Verizon's (not to mention the phones and the fact that you can do high-speed data and a call at the same time).
Did T-Mob start pro-rating their release contracts yet?
Don't know.
Am in the uk so cannot get at and t..
boo!
yep, get the same issues, whereabouts are you? im in rainham, and have to turn off the 3g to get reliable incoming calls and make calls, dont have to go too far and it works ok!
romford / ilford seem to be ok with 3g switched on.
I'm in Ilford and when set to Auto band miss calls intermittently so can't use that setting reliably. I wondered if there was a way to set the phone to use only 3G so it doesn't keep trying to switch between 3G and GPRS?
I'm from Indonesia and discovered that sometimes when my network switches me to 3G automatically, I can't receive or make voice calls.
So, I went to phone -> menu -> options -> band -> select network type to GSM istead of AUTO or WCDMA
Unfortunately, I left the 3G coverage area before I had a chance to see if it made any difference

Same here, in central London - have been ranting about this for some time over at Modaco eg here. Not a clear answer apart from perhaps swapping the handset but its hit and miss
Its a really severe problem and I'm losing the plot a little with it. Gutted.
BTW, if you need a way to quickly switch between the two modes, read http://forum.xda-developers.com/showthread.php?t=345524
There are about fifteen threads about this on here and on Modaco. Its a fact of life with 3g and HTC devices.
It is primarily down to relationship between the network cells and the device.
3G cells are notoriously unreliable and need a lot of maintenance - if you report a problem cell to your network, they may check it out - although they use their own testing to determine which cells need fixing.
Some devices do have weaker transceivers and hence the odd occasion where a device swap helps - but 99 times out of 100 its the network cell. And thus the reason that users find their device works fine on 3g in another location.

Phone signal question

Anyone experience no phone signal after flashing a ROM to your Pure? I got the device two days ago and immediately went to flash it using one of Duttys roms and also from Tess (IV). With both attempts I get no signal bars whatsoever. That being said I get an "H" where the "3G" used to be. I know that some of you have talked about the HSDPA but even though I have been doing this awhile I am stumped as to why I would get no signal bars. As long as HSDPA doesnt result in more charges from my provider I could care less about that. Hope that makes sense and I hope that someone has some information for me!
Thanks!

Hi, yes, I have seen the situation on some ROMs where I get 'no bars', but the phone seems to be operational anyway. My suspicion is that it's a problem with the root software from Microsoft, not the ROM chef, since it goes across ROMs.
3G vs. H has no bearing on the problem. The H just shows that the phone is connecting via the higher-speed data linkup. Some providers charge more for H, others don't. You'd have to check with yours.
Thanks for the quick reply. Is there a way to figure out if AT&T charges extra for the "H" connection speeds?
Also, are there any roms out there that have figured out a way to slightly increase the size of the virtual keyboard for easier typing? Both roms I have used so far have kept the keyboard the same and not sure if there is actually a way to increase the size. Lastly, I am reading up on roms trying to find one that I would like but one piece of information eludes me. Does the rom I am researching support landscape mode in Start and all other aspects? Right now I get landscape in web browsing, email and that is about it. I may be missing something here but thought I would ask for clarification.
A note about the Tess IV rom is that I really loved it. It was super smooth and very fast unlike the shipped rom from AT&T.
I found the original rom to be bulky and slow in responsiveness when moving between features or applications. I am sure that is why others moved away from it as well.
AT&T does not charge extra if you enable HSDPA. This is my second AT$T WM device and I have enabled "H" on both.

How do you enable "H" or force it on?
The type of signal is dependant on whats available in the area you are in. As far as I know you don't force "H" to come on, your phone just accesses the best available signal you allow. If " is it then.....
My att plan is the basic plan with the $30.00 data (unlimited) that is required when you buy it. No charges for "H" access for me.. good god, with the way I use slacker all the time, that would bankrupt me in a week.. lol

I'm using the ENERGY Leo ROM, and notice the same.
Thing is that while H is showing I get no bars and no phone connection. Then the phone automatically switches over to 3G and dials out. This can take up to 10 secs - so, can be annoying!
Could this be a locational thing, as I notice this happening in one location only - perhaps where the signal is not strong enough to utilise the H connection.
Or, is it that H is used for data and 3G only for telephone calls?
H is actually HSDPA and is the 3G data connection. 2G equivalent would be EDGE for example. You will only pick it up if A) Your device supports it, B) Your carrier provides it!!, and C) Your are in a stong enough signal area.
You mention that you flashed to a custom ROM but have you flashed your device to an updated Radio ROM? This is the part of the phone that deals with communications including Voice, Data, WiFi etc. Using a good one makes a world of difference.

No, I thought the updated custom ROM would also update the radio.
What is your reccomendation for the radio?
How do I find out radio version I've got?
I dont have any specific useage beyond taking calls, and updating Twitter, weather etc.
What version do you think is best?

Some ROMs do include the radio, such as Dutty's HG 9 & 10 ROMs.
The radio version is usually included in the name of the ROM.
For best radio, it depends on your carrier and location.
To find your current version, soft reset, it is listed at the bottom next to "R" upon booting.

I checked my radio ROM - it was .17.
Just updated the radio to .91 - immediate improvment in access to 3G cellphone signal.
Of course, I need to use it for a couple of days to get an accurate feel for improvement.
BTW. I'm based in the UK.
I've had varying success using different versions but .57 has always been head & shoulders above the rest for me.

[Q] phone conectivity stuck at H

Hi All,
I have a weird issue. My phone seems to be permantently stuck at "H" (HDSPA), it never switches back to 3G. Does anyone know what the problem could be?
It's sucking up my battery real fast.
I'm currently using a Generic Northamerican R3 rom. My phone is the X1a model.
Help would be much appreciated, thanks.
EDIT: I should also add that "Bands" option is set to Auto (both of them). If i play around i can get it to use Edge only, but thats not what i want. Id like it to work as it should, 3G when data is not being used, otherwise H.
download WMlonglife.cab n setting it..i forget the link..u can googling...
to the OP:
here's some info to let you figure out if you actually have a problem at all or not:
H(SDPA) is a data-extension of UMTS = 3G, E(DGE) is an extension of GSM/GPRS (always data, voice is either GSM or 3G). with band-setting, you just choose between gsm or 3g, if you get edge or hdspa for data depends on what your provider is delivering in that area.
standard behaviour with hdspa is to show the icon only if there's actually data transfered, if not it should show the 3g-icon. but some providers break that standard and will always let the phone show H.
so either you have one of those providers and are just complaining about the higher power-consumption of 3G compared to GSM. then normal power-saving measures come into play, search for them, there's a thread for it.
OR you don't have one of those providers, the symbol should fall back to 3G. this would mean you have constant data-transfer going on, causing higher power-consumption. if that's the case, remember what you installed and set to autostart (skype, irc-client, webradio... - web-stuff running in background)

Verizon range extender problems

Anybody else on Verizon using a Verizon brand extender? A search found one other old thread but no definitive fix. The one proposed fix was to set the phone to 1x speed to force it out of hunting for towers outside and hope that 5.1 fixed the problem. I just got my phone from Verizon, it came out of the box with 5.1, so it would seem they didn't fix it. And I can't seem to find how to set it to 1x. Only from global to LTE. I'm dropping calls, having problems with texts, and Verizon support admitted it doesn't seem that my calls are going through the extender. They said the 6 should be perfectly capable of utilizing this extender. My note 3 worked perfect on it, and as far as I know the wife's note 4 does as well. I get the beep like it's calling through it, just not the signal. And this phone doesn't have a separate icon to show if it's connected, intermittent, or never recognizing it. Is this a known issue and I just didn't search properly? Running 5.1 LMY47E, bone stock. I warrantied the phone, same thing. So this thing is literally about an hour out of the box, no mods. Looking forward to rooting and running some roms but I'd like to know I've got any issues ironed out before hand. That way I'll know any future issues are rom related, not hardware
TIA
Unfortunately there is no fix unless Verizon decides to somehow upgrade the software/firmware of the extender. I'm surprised that Verizon tech support didn't inform you that the extender is not capable of utilizing 4G or enhanced network capability and can only function with 3G or less. I spent a bit of time on the phone with tech support and requested a problem ticket be raised to Verizon engineers to get a definitive answer -their response was that the extender can not do 4G but only 3G. The way I was able to get my Nexus 6 to successfully connect was to turn the "Enhanced 4G LTE Mode" off and then it was able to connect. This is not a nexus 6 issue only but from what I've seen is any phone that has that enhanced 4G setting - my wife's Iphone 6 is also unable to use the extender unless that phone capability to use 4G/LTE is turned off. Surprised you even got the beep as never of our phones get that connection beep unless the 4G/Enhanced switch is off.
I'm surprised (maybe not) that Verizon continues to sell the same Network Extender even though it no longer works with the new network capability or with phones that use that technology. Also brought that up with them during my call but of course that wasn't addressed. I also got no information as to any plans to upgrade the extender firmware but I'm assuming the lack of info speaks loudly.
Again one can never be assured of whether the information they provided me is accurate or no so if you find out differently please post back.
Also, my Nexus 6 is rooted and I have tried numerous ROMs and the ROM makes no difference so that isn't going to fix the issue.
Hopes this helps a bit.

This helps a ton, thanks! I've always known that the extender didn't support anything above 3g, but it's never been an issue since my router took care of data and 3g was plenty for calls and texts. But I was thinking it had something to do with this... I haven't researched any of this new stuff about xlte or whatever it is but I know it seems the phones are changing to support some mods to the network. I haven't paid attention because my town is usually the last to receive this sort of technology. Big cities were going to 4g soon after we upgraded to 3g...
Can you tell me if the pic below is the menu that you used? I can't find any setting anywhere else that specifically says 3g, to try to force it into a mode that the extender understand.
you can dial #48 and the phone will tell you if you are under network extender coverage
The setting that needs to be disabled is on the same screen where you set the preferred network type (actually under the one you are displaying). It should be the next setting following the Preferred network type. It actually has a slider to turn on or off. Now, I'm not running stock but I believe it should be the same or very similar on stock.
Not on my phone or i'd try to include a screenshot. Hope this helps.

Oh yeah, I forgot about that detail. The Verizon tech had me do this. It actually told me I was connecting through the extender. And the call seemed relatively clear. But I could hang up and immediately dial my voicemail or some other number, get the beep from connecting through the extender, but the call would be spotty and cutting out badly. And the tech was confused by this because it wasn't showing on his system that I was connecting through the extender even when the #48 said I was. Strange things going on with this...

I'm not typing on my phone either, to include a screenshot. But I'm looking at it. The option directly under Preferred network type (which I have changed back to the default Global), is System Select. The subtext under that says "Change the CDMA roaming mode". And within the menu, the two options are "Home only" and "Automatic", of which Automatic is the default. Is this what I'm looking for?
Do you have Advanced Calling activated on you phone? Not sure if that is the issue or not but on your Verizon Wireless account you should see Advanced Calling (I believe that is what it is called) under "Manage Products. & Aps" - you should have the option to add it to your account. It is a free service but as I understand it you need to include it on your account for the phone to use Volte and it might not show up in settings if it is not an active service on the phone. Again, I'm only guessing here since I'm not on stock but I do believe I've had the option since I got the phone and I added HD calling right after I completed the pre-order.

I will log on in a bit and look. So are you suggesting that I enable it, or disable it? Is it believed that HAVING this feature is what is killing the link to the extender? Sorry for the dumb questions. Like I said, I've never had to look into the new tower technology before because I don't anticipate getting it in my area. I never thought about it still affecting my service anyway, even though we weren't getting it... figures.
For me to use my extender the 4G enhanced/LTE needs to be disabled. What I don't know is whether that setting shows up on the phone if the Advanced Calling isn't active on the account. If it doesn't show up there might be no way to disable it. I know it sounds somewhat illogical but again
I'm guessing to some extent given that I have it on mine and I really think it has been there from the start.
Sorry I can't be definite with it.

LG G5 RS988 LTE connectivity problems

Hi guys. I'm a long time xda lurker who just purchased a LG G5 RS988 because I read in the forum that I could unlock the boot loader. Soon after activation (MetroPCS) I noticed the LTE would not stay on. In a area where LTE is very strong, it makes no sense to drop to HSPA. The only time LTE works is when I restart using network select under network settings and only lasts for under a minute before dropping to HSPA. It never recovers to LTE.* I also noticed that the phone selects band 2, unlike my other MetroPCS devices which normally utilizes band 4. I called MetroPCS and have done everything I could with them and including setting my APN correctly. So I figured that I would have to flash my phone with a different ROM to ever fix it. I ran into a few major problems during my adventure to get it the boot loader unlocked. I have the BRIGHTPOINT model G5 (who ever the bleep that is) and came with 10c Android 6. I followed all the directions in the xda threads and quickly realized 10c had no fastboot mode. I tried all the button combinations and adb reboot fastboot and nothing would bring it up. It didn't even have a recovery mode. So my adventure took me to LG Bridge application for windows. I ran that and thank my lucky stars I found a update. I upgraded to 10h which switched me to Android 7. First thing I checked is if my LTE problem was resolved, which it wasn't. I took another shoot at fastboot and to my amazement I am now able to enter fastboot mode. Excited, I went to LG development site, signed up and ran the tutorial to submit my imei and device Id to receive my boot loader unlock bin/code. I submit my information and I get a rejection after submitting the form on site that says: Unfortunately, your device(United States, (BRIGHTPOINT(USA))* )does not support unlocking the bootloader.
Now what?* I can't flash or at least I personally don't know any work arounds and I can't root unless there is some method unknown to me. How do I force a new ROM into the phone without bricking it and how do I fix this LTE issue? Someone, anyone, any help is appreciated!!
OK let's try this.
Someone at least help me with a couple questions.
#1 is it possible to root without unlocking the bootloader on my LG G5.
#2 is it possible for me to flash my G5 with any other update? I am on 10h, are there any other updates I can flash?
#3 is it possible to flash any updates without unlocking the bootloader?
Thank you in advanced.

1) You can root without unlocking bootloader only if you're lucky enough to find one of the universal rooting apps or PC programs that actually works on your device, you'll have to try them all for yourself to see if they work.
2) if there is/are stock updates you can flash them.
3) you can flash updates without unlocking bootloader if they are stock updates, but you can't apply stock updates if the device is rooted, it has to be unrooted, has to have an unmodified system partition and has to have stock recovery.
You can't flash custom recovery or custom ROMs with a locked bootloader.
Your issue probably isn't in your device software. It's more than likely an issue caused by the network itself.
Metro PCS is an MVNO(sub contracted cellular provider that uses another providers network). They have to pay the network they are under for the data that their customers use. This often means that they limit or throttle data speeds to make it more cost effective for them, so they don't lose money paying for the data that you use on the network that they are paying to use.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE
Thank you so much for answering all my questions. I have tried using all of LG software to flash, however I ran into problems with all of them. From unable to load some model or no detection of my phone.

I am on a unlimited data plan and I barely use data every month because I have wifi. I used a little over one GB this month so I have no idea why they would throttle my bandwidth. I have read in this forum of other people with RS988 BRIGHTPOINT version and having the same issue. Something about the software being directed to perform a certain way on CDMA even though the phone is unlocked for both technology's. With that being said, it would still be unlikely to fix the problem by somehow flashing it to a non BRIGHTPOINT stock?
How do I flash when none of LG software works for me and what can I flash it to that's not BRIGHTPOINT?

Thank you so much for answering all my questions. I have tried using all of LG software to flash, however I ran into problems with all of them. From unable to load some model or no detection of my phone.

There are a few factor that could be the cause of these kinds of speeds even though you haven't exceeded high speed data limits.
1) They are trying to keep bandwidth at the bare minimum level for high speed data to keep their cost down but aren't doing a very good job of it and actually dropping too low.
2) Maybe it is due to the total amount of data being used by all of their users at a given time and they drop the speed to control how much total data they are having to pay the network they are under for.
3) Total area coverage and proximity to towers along with the amount of traffic on those proximal towers. In other words, maybe the load on the system in your area is very high and they are trying to limit it for cost purposes.
As for what you can flash for whatever reason, I haven't a clue. I'm just trying to potentially explain the cause of your data speed issues.
I deal with the same issues on my cellular network which is also a MVNO network under Verizon towers, I have unlimited plan also and I don't exceed my high speed limit, the thing is, it has done this with 3 different devices on this same network. This tells me that software is not to blame, the cellular provider is the cause. I live in a 4G area with plenty of coverage but I've still had my 3G device and my 4G devices frequently drop to 1x speeds for no reason and do it for extended periods more than just a few minutes.
And my wife's 4G device frequently drops to HSPA+ and HSPA speeds, even 1x sometimes, that device is also on the same network that mine are. See a connection yet? That kind of pattern can't be a device/software related issue.

Thanks again for your quick response to my last reply.
I don't think they would just pick my phone to do this to. I have a family plan and my fiance has had three phones since we been together and none had this issue. I have personally had two other phones and they didn't have this problem. With all the past and current phones, LTE coverage is really high. We live right next to a tower.
I believe you when you say some networks can and will do that to people. But all the evidence to the problem points to the phone because I doubt they would single out my phone. I am actually using the same sim card from my LG G4 (the phone before I upgraded to G5) which the G4 worked perfect.

So far, so solved.
I have had the exact same issue you described @Skimpypimp . Last year I switched onto a family member's at&t plan and my Nexus 6 would not stay on LTE, despite the APN being correct. Through contacting att reps I discerned that they really just wanted me to buy a phone from them (their IMEI #). I called them and gave them my "new" IMEI, and suddenly I had pure uncut LTE.
Fast forward through me being scammed on Craigslist by buying a rent-a-center LG G5 a few months later which I finally just got working this month. Now I'm having the same issue as you. LTE for a minute, then back to hspa. I just tried switching it to LTE/CDMA mode and I'm using the att broadband APN (what is used on tablets) instead of the nxtgenphone APN. It's been 10 minutes so far and still LTE. IDK if you're able to take similar actions on your network, but that worked for me.
Good luck!!
Ninja edit: I am using RS988 stock rooted with unlocked bootloader. Android 7.0

Hi guys. I'm a long time xda lurker who just purchased a LG G5 RS988 because I read in the forum that I could unlock the boot loader. Soon after activation (MetroPCS) I noticed the LTE would not stay on. In a area where LTE is very strong, it makes no sense to drop to HSPA. The only time LTE works is when I restart using network select under network settings and only lasts for under a minute before dropping to HSPA. It never recovers to LTE.* I also noticed that the phone selects band 2, unlike my other MetroPCS devices which normally utilizes band 4. I called MetroPCS and have done everything I could with them and including setting my APN correctly. So I figured that I would have to flash my phone with a different ROM to ever fix it. I ran into a few major problems during my adventure to get it the boot loader unlocked. I have the BRIGHTPOINT model G5 (who ever the bleep that is) and came with 10c Android 6. I followed all the directions in the xda threads and quickly realized 10c had no fastboot mode. I tried all the button combinations and adb reboot fastboot and nothing would bring it up. It didn't even have a recovery mode. So my adventure took me to LG Bridge application for windows. I ran that and thank my lucky stars I found a update. I upgraded to 10h which switched me to Android 7. First thing I checked is if my LTE problem was resolved, which it wasn't. I took another shoot at fastboot and to my amazement I am now able to enter fastboot mode. Excited, I went to LG development site, signed up and ran the tutorial to submit my imei and device Id to receive my boot loader unlock bin/code. I submit my information and I get a rejection after submitting the form on site that says: Unfortunately, your device(United States, (BRIGHTPOINT(USA))* )does not support unlocking the bootloader.
Now what?* I can't flash or at least I personally don't know any work arounds and I can't root unless there is some method unknown to me. How do I force a new ROM into the phone without bricking it and how do I fix this LTE issue? Someone, anyone, any help is appreciated!!
