[Q] Touchscreen lag - Xperia SP Q&A, Help & Troubleshooting

Hi everyone !
I recently got my digitizer changed (apparently phones don't like faceplants ) and when i got it back I noticed a "slight" change.
Symptom :
When I touch the screen and slide my finger there's a little lag before the move is recorded by the phone, like, I have to move my finger more than 1/2 inch away from the starting point or it consider my finger didn't move from it. (thus resulting in little jumps when sliding through menus or if you wanna draw a circle it start by drawing a straight line :silly After the phone catches up however (so, as long as I keep my finger on it) it follow up well just like it has to :good:.
Resolution tested :
Through research I think my problem could come from a change between the dpi of the stock digitizer and the one I got in replacement, so the stock touch_slop value isn't adapted anymore. I tried to change it in my build.prop, but it made no difference and the problem is still here. Although it doesn't mean the problem doesn't come from that (The way Android handles touch_slop has changed in the latest versions) I don't know how to fix it and I need advices. Has someone already encountered that problem ? How can I fix it ?

Firstly, Did you ask SONY to change the digitzer or from an external vendor?
Secondly, was the digitizer flex cable given to you when you purchased the new one?
Thridly, Is the digitizer properly placed on your screen?

External vendor, I firstly went to the official support and they said It would cost me the price of the phone, , so I didn't insist on the "official" way

I'm not the one who changed the digitizer, I went to a local tech shop, the only thing I was given was my phone.

Yep, from an external point of view you can't say it has been changed (If you don't mind the big cracks that were there before )

Ok so the tech shop might be the problem. They might have used an incorrect cable and might have also provide you with a bad digitizer. The Cable is essential as it transfers touch signals to the board and if its faulty or not of good quality the digitizer might as well be useless. For the digitzer you might want to check with them on what digitzer they used and if its those cheap 'china' brand types then it's also not good for your phone. Quickly get to the shop and ask them to help you because a faulty digitzer might break your whole device :crying:

Yeah it might be, but as I said, it's only the first "move" that lags, it record the touch at the exact moment I touch the screen and after the first 1/2 inch is past there's no problem anymore so I don't really think the problem is related to that.
Actually, I think there was a similar "problem" a few years back, it was related to the way Android make a difference between a click and a swype. Its create a deadzone around the first point that's touched by your finger, so that every time you click it's not considered as a swype (because biologically you just can't click only ONE pixel). The size of this deadzone was the same on every phone and was related to the touch_slop value. At some point on some "newer" phone the size of the digitizer was bigger but not the dpi and so the deadzone began to be a hindrance more than a conveniance, cause its size grew with the size of the screen. I was then decided to change the way it was handled by the system and a new method has been implemented, using mtouchslope value, that's not just a number of pixel but that's calculated from the dpi value of the digitizer. SO I think that the digitizer I got isn't the same as the stock one (just like you said) but I think there's a way for me to fix the problem in a more "software-way". The only thing I don't know here, is how can I change the digitizer's dpi value that's stored inside the phone.

Dude you should have used the reply funtion so I could reply more quickly
Anyways there is Resolution Changer by NoMone in the Play Store that deals with the resolution changes and DPI too. >>>

Yeah, I already looked for that, and the dpi value that's changed by this app is also present in the build.prop file but it only changes the dpi of the lcd screen and not the digitizer's one, so it doesn't really help me in this case. But thanks for your concern anyway

would xda lcd screen works for xda2, i think secially LCDS

i was wondering if xda lcd screen works for xda2, i think secially LCDS sjould match, anyone tried it or at least knows for sure?
from what i understand from screenprotectors
then they are not the same size of cause they may not matter
since they have the same res
but another problem is that xda1 screen 4k colours
and xda2 is 64k colours
and mw2003 report that colour number
so this make one believe that the screen have a driver
and this would indicate that the rom of a device only have the driver of the screen that it comes with
but i'm not sure if one could pull it off of cause
so buttom line it doesn't work & its actually usless to try?
but i'm not sure if one could pull it off of cause

[Q] Just bought nexus one - problem with screen calibration

Hello,
I have recently bought nexus one and now randomly I have problems with the screen - I click on one place and it does something totally differently. It is fixed if I turn off and on screen. Before posting the question I did do my homework - I found this
- Q5: Sometimes my screen registers touches in incorrect places, and I need to turn the phone off and on to make it work correctly again
A: This is a hardware problem, nothing can be done about it. Nexus One's digitizer sucks.
in FAQ and found out that screen can't be calibrated. Now the questions that I have are:
1) Do all of the nexus ones have this issue? Would you advice me to return the phone and get a different model or replace for the same model (I already have bought screen protectors and case).
2) How often does this happen?
3) Is this a truly a hardware issue or software issue?
If this is a hardware issue - can it be fixed by software (e.g. by restarting the driver for the digitizer every minute or something like that...). I've read somewhere on this forum (or on a different one) that motorola had similar issues and they have released a patch that has fixed the issue
4) Are their any hopes it will get fixed in future releases?
5) People who have the same phone - how often do you have to turn off and on it (the screen - not reboot)?
Any other issues I should be aware of?
About the phone - its android 2.3.4
1) Yes. Some are more affected, some are less, all have it. It also depends on a zillion of factors - including climate, average finger moisture, etc.
2) See answer 1.
3) I've never looked at the code, but Nexus One is out for a year. If it was possible to fix - I'd bet it would have been done by now.
4) See answer 3.
5) See answer 1.
You've done your homework, but still came to ask "just in case". Well, the answers didn't change for the last 1/2 year.
Thank you for the quick answer.
If all the phones have this issue - why people are still using them? Or this is something they have just got used to? Also I understand that the frequency is different for everybody, but can I please have some numbers? Its one thing if it does it once a day or once a week and totally different if it does it every hour or every 15 minutes of use... Can you please let me know how often it does it for your phone? Also are you using screen protector? Is there any corolation between screen protector and and frequency?
Screen protector is known to cause less sensitivity and less responsive screen, which might account for some of the trouble.
People got used to it.
It mostly depends on the moisture and heat - the hotter the phone, the more likely is the screen to fail. Without moisture and with casual use it'll fail once a day or so. When playing a game, it can fail more than once an hour.

It happens to all nexus ones, its a hardware problem. But it only happens about once or twice a week, so most people just live with it. Just turning off then on the screen fixes it, so only takes a second to clear the error.
Also heat seems to cause it, particularly when its charging.
I go weeks without ever seeing the issue. Other times I see it once a week. It sucks but not a huge deal really.
Hi guys,
Just a quick question.... if this problem is hardware and relates to the digitizer then is it worth just replacing the digitizer?
I notice you can purchase a replacement digitizer on eBay.
Is it worth a try? And if so, is the N1 easy to take apart?
I've taken other phones apart and repaired them so have some experience.
If you replace it all you're doing is waisting your time. It will be the same thing. It is not like the digitizer is broken/failing or anything. It just sucks. Its not broken. Better way of thinking of it is a hardware limitation.
Hi guys,
Well, not wanting to be beaten by this screen problem, having suffered for over a year, I decided to take the plunge and buy a new digitizer off eBay. Cost about £20.
Found a couple of vids on Youtube which show you how to take the phone apart etc.
Two months on and all working fine. Not one single screen issue since replacing the digitizer.
Now a VERY happy Nexus One owner. Just wish Vodafone or HTC could have done the same thing on anyone of those four occasions I sent the phone for repair!!!
Now also running the MIUI custom OS... what a fantastic OS!!
Well, I'm pretty surprised no one filed class action suit against Google or HTC for supplying faulty digitizers on Nexus One

wow! which seller did you buy it from? is it an OEM part or third party? was the multi-touch issue fixed e.g. X-Y axis all over the place when fingers come too close together? does it now register more than 2 fingers?
The seller on eBay was e_cell. Search for this item to see the digitizer I purchased: 190567591678
It was listed as: 'GENUINE HTC NEXUS ONE G5 TOUCH SCREEN DIGITIZER + TOOLS'
I used a video on YouTube to dismantle the phone and insert the new digitizer.
Search YouTube for 'Google Nexus One Screen Replacement & Take Apart Directions'
Sorry I haven't include direct links but the forum wouldn't let me.
Note: Once I'd taken the phone apart I ran a warm hairdryer over the old digitizer in order to soften the glue that holds it in the frame of the phone. Then I slowly eased the old digitizer out of the frame and inserted the new one. The original adhesive in the frame will hold the new digitizer in place.
Tip: Make sure you remove any dust or finger prints from the new digitizer before reassembling the phone. You'll kick yourself if you forget to do this as they will be visible on the inside of the digitizer and it will drive you mad! I made this mistake and had to take the phone apart again to clean it up. DOH!

I would love to know what sort of problems did the new digitizer fix?
My problem was when I touched one area of the screen another area would respond.
So a screen calibration issue.
It was most noticeable when texting. For example I'd press a key on the top row of keys and a key on the bottom row would respond.
A work around was to press the power button to put the phone into standby and press it again to continue using the phone. Sadly the problem would always come back.
I'd also have problems selecting App icons. I'd press one and another would respond.
I asked both Vodafone and HTC to swap out the screen but all they ever did was flash the rom or say they couldn't find any problem.
The issue I had is well documented on the internet.
So glad I never gave up on this.
wait so a new digitizer fixed the issue?
so theres a different version of this digitizer?
or is the model and product number still the same?

Do you have the part number of this new digitizer you replaced? it turn out there are a number of OEM parts with different parts number
Unfortunately I can't state the part number as I don't have that information.
I simply searched eBay for a digitizer and looked for a good seller who appeared to be trusted and had a good feedback rating.
I'd bought from 'e_cell' before and knew they provided a good service.
All along I knew I was taking a gamble when buying the digitizer but the problem with the phone was so annoying I decided it was my last hope to get the thing working properly.
I've had the phone close to a year and a half, and during that time its spent most of its life either away for repair (Vodafone or HTC) or sitting in its box because I refused to use it. Instead I bought myself a second hand iPhone 3G off eBay to get by. Things were made worse by the fact I am tied into a two year contract with Vodafone.
So trying a new digitizer was my last throw of the dice, so to speak.
And the fact it worked is brilliant. I still feel this phone (Nexus One) is the best phone I've had, and I've had quite a few.
Please remember... if you decide to do what i did then see it as a gamble. There are no guarantees in life.
Oh, and be real careful when taking the phone apart and reassembling. It's not particularly hard but there is always a risk you may damage something. So be warned.

Thank you for the information, so it turn out nexus one have quite a number of unresolved issues. I was wondering why didn't big G did not order product recall for people with faulty digitizer?
I looked around and found that a number of users have having all kind of issues after replacing the digitizer. Geez...what should I do? Perhaps I should take it to a professional phone repair shop?

Well, luckily for me no problems as yet (though never say never!).
The most important thing when taking the phone apart is to take your time, and memorise where everything is located. Be firm but not heavy handed. There are some delicate parts inside the phone so you have to be careful.
Common sense really.
I've had no issues with signal strength. I get HSDPA most of the time, or standard 3G. My data (internet) is working fine and so is GPS.
Inside the phone there are a couple of connectors that control signal so you have to be careful and make sure if they disconnect that you reconnect them again properly.
I build and repair computers and laptops. If you've ever taken a laptop apart that has wireless LAN capability then you'll know there are specific wires which connect the antenna to the motherboard. The same applies in the N1 but on a smaller scale.
Good luck to anyone who tries this!
does anyone from the UK have a source to get a new digitizer from that fixes the heat related issue?
ebay has one for £22.50 (id: 10goodseller2012), and i'm almost ready to click BUY, just want to see if anyone else has more info before i 'blindly' click buy...
edit: i should add, 'e_cell' seller no longer has the N1 digitizers listed...
No matter what anybody says, replacing the digitizer itself won't fix the issue. It is deeper than that. It is the digitizer mixed with the onboard hardware to interpret the digitizer inputs. Usually it ends up just being heat related. I haven't had the issue with my phone for awhile, but that is because it doesn't get as hot as it used to with older versions of CM, but if I have it in the sun, in my car dock, using GPS, it will freak out all the time.

i too was sceptical, and i still am.
however, I've replaced the digitizer and so far it's perfect! i'm not sure it's placebo as i could get it todo it 100% of the time.
prior to ordering the new digitizer, i ran tests to see at what temp ranges the screen would play up - according to the battery temp (Battery Monitor Widget), it will play up over 40c.
what i SUSPECT is the fix, is the digitizer i bought is a newer hardware revision than the one i had. the new digitizer did come with it's own chip on the flexible PCB.
i did mean to write down the new digitizer number and compare from the old one to see if they have revised it - alas, i forgot to get the new number. (old one is 940-473-1r5)
its been installed for almost 2 hours now, and on test for around an hour to build up heat - screen on full, camera on, GPS on (using aLapRecorder HD) and it's perfect. before i could guarantee a problem with screen dimmed, camera on, GPS off, so early impressions are good!
I'll give it a proper test tonight on the way home from work - it'll have the windscreen blower aswell..

Nexus One Screen problems

So it just happened this past Friday, a white bar appeared on the right side of my phone's screen and shortly after my phone ran outta batteries. When I plugged it in to charge the screen just slowly showing a blossoming of pixel colors all over the screen. If i leave it alone it will boot into the OS fine and I can hear all my notifications and everything seems to work fine but the screen just turns black with a thin blue bar of light on the top. Is there anyway to fix this aside from replacing my screen? and is it a digitizer problem?
now the screen is just completely black when i turn it on, but it is still responsive. I can still unlock and open apps and swipe the screen, etc. Does anyone know what is wrong and what needs to be replaced? Please help!

your LCD has gone bad. this is a fairly easy repair, but there are a few places you need to be VERY careful or you can break things (like your power button)
the Nexus One has TWO different models of LCD and you HAVE to use the one that was originally in your phone.
One is made by Samsung and is fairly common/easy to find. its gonna run you about $30-50
There is also an LCD made by Sony which is a little more difficult to find (and mostly used on the Desire) but it costs anywhere up to $100+ so lets hope thats not yours :]
if you arent comfortable doing the repair there is a company called Cell Phone Repair that has stores in almost every state and they even take mail orders if you are not located near one.

He told you everything in detail already, but if you are a newbie and have never done things like this, i suggest you find some other people to get your phone repaired, it cost much less to pay a screen repair fee than get a new one

What do you guys think? LCD or something else?

Your LCD its fine. I would say your main board its gone, namely you graphics card or CPU. As you see it only happens when it requires more usage from CPU.
If you overclocked the CPU than thats it.
But it seems more related to graphics.

I still have the original LCD, where I can only see half of the screen, because its broken.
And no mater what I do, it doesn't do this, so I ruled the graphics out. But maybe because its only displaying half of the screen that it doesn't need that much power of the GPU?
Damn... I need another m8 mini for testing!
Thank you for your time!
Anybody else?
In that case maybe something went wrong in the assembly.
Try to remove and assemble it again. Maybe it's just a connector thing.
Sent from my HTC One mini 2 using XDA Free mobile app
I disconnected all cables except battery, digitizer and lcd... still the same, BUT
after I assembled it again i left it in the freezer for some time and cooled down it works fine, sooo...
it could be a CPU problem (or mainboard) and not the LCD... or does the LCD react to temperature? doesn't seem like it.

It looks like CPU then, but if it works with the original LCD then its not. Although you only see half screen, the process will be the same so it should crash too. It a lot of work but try to put it back and test it.
Also (you probably done it) have you reset your phone to factory settings?
I'll try to get a new screen for testing, the old one is useless.
This really bugs me. Why is it acting up on CPU usage?

I did a factory reset. Now I'm thinking of new firmware flash. I don't know... if I only could get another lcd, that would be very nice.

Good of you to show that test.
if you notice it only got very bad when testing 3D graphics. So its the Graphics card but...
could it be something its missing from assembly and the graphics card its now touching the LCD transmitting too much heat?
Or you could ask for a LCD replacement if you think that one its faulty. Im sure the seller would help you out.
Note: a lot of things could cause the board to burn, Static being the most important. Also you say you disconnected/connected the cables with the battery one on? A simple touch with the screwdriver in the wrong place would be enough to damage the mainboard more so when still receiving power from battery.
Thank you for helping out!
I was very careful with the connectors, only using plastic tools on them.
It act's up on CPU usage. 2D graphics with androids flying around is good. The 3D test has loading time, so the CPU could be the problem there. I'll try another GPU benchmark.
There's another thing that bugs me. The LCD i got of ebay has one thing missing (see attachment)
It's actually my friends phone. He dropped it. And it was acting up on the broken LCD also, so I'm really starting to think it's the mainboard.
But to be sure, I'll try to get my hand on another LCD.
Will report here as soon as I get one.
I already contacted the seller. He cannot access youtube, so I sent him the clip to gmail. We'll see...
OK, here's a little update.
I think that the GPU is ok due to this benchmark

and I think it's the CPU because of this

Kind of lost now. GPU seems fine but also the game would need CPU for processing so... Maybe some other thing? (Allergy's)
Lets wait for seller to replace LCD. If after replacement still the same then you'll need a new board.
Maybe some other tech have better ideas?
Keep us updated
OK!
Here's 'n update (if someone cares)
It's definitely the LCD fault. And I know this because I got an other One mini 2, attached only the LCD cable to it and voila! the same problem.
So... nothing wrong with the GPU, CPU or anything. A faulty LCD from ebay.
Now.
That wouldn't be much a problem if PayPal was a "pal" and got me a refund, but that's another long story I won't write about here.
But I still want to know whats causing this LCD to do this crazy stuff.
Please, if someone can solve this mystery to me.
Thx!

Could be lots of things or just a bad cable, or the connectors. you probably need to get another one.

Replacement screen?

Hey guys,
I managed to drop my 3T a few days back, cracked the screen, over the course of a day it became fully black, rendering the display unusable.
I've seen some posts of people complaining about how bad their replacement screens are. My local GSM store said they could order a (semi-genuine, lol) display for around $150 - I'm assuming people who are having issues with their replacement screens got some cheap ones off of eBay.
My question is, would this replacement cost be a huge ripoff with me ending up with a somewhat ****ty replacement screen, or is it just worth buying a new phone at this point?
EDIT:
Okay so, my order arrived, took it to my local GSM store, they swapped the displays. Luckily everything works fine, I've got no dead or stuck pixels, screen off gestures, notification led, back and menu buttons, fingerprint reader, everything works just fine. The only little issue is that my actual display part doesn't fit quite fully into the frame, so it's like half a millimeter "elevated" on the left side. Probably not going to cause any issues, it's just that dust can get more easily under the screen.
DIgitizer is also recognized by default, no need for custom kernel, thank god
Try to find some OEM screen (50 - 60 $) its original but not from oneplus

Do either of these look good to you?

I was told they can only replace the screen if I order it with frame, which both of these sales can do, I'm just not sure if there's anything I should be looking out for to clarify whether or not they're going to be a scam
I love this phone a lot, really don't want to buy a new one, and I also want to triple check before getting a replacement screen, just to be sure.

Some of them have massive issues with unified roms and need a patched kernel to always properly switch on. See the los-16.0 thread for details. The main issue seems to be, that there are oem displays out ther, which claim to be a5 but are actually a3.
@Lada333: if an original (not semi original, not nearly original, but original) replacement screen is too expensive, I'd recommend a new phone to any flashaholic... Maybe you get a good deal on a used (but original... ) 6 or 6t.

I ended up buying the one from the eBay listing ("original" black + frame). Haven't looked into the issue you mentioned earlier, but I'd be fine having to use a patched kernel. I looked around for new phones (I couldn't stand buying a used one), but none of them really seem to be worth it for me. It's either some dum-dum popup camera, or some ugly notch. 3T's design still takes it all for me. A 5T would be hella nice, but then again, not in production anymore, and getting a second-hand one is no deal for me.
I have used official Oneplus repair in my country and was satisfied. its important to order the repair on official site. i've attached pricelist

As far as I know, there's no OnePlus repair here in Hungary, also I haven't bought my phone directly from them - last time I had a repair in question, they told me to contact my Point of Sale, figured they'd advise the same this time too.
Thank you for the tip though!

I bought AMOLED screen with frame from aliexpress for my 3T, working well just for 2400/- INR.. Took around 28 days to deliver to India.

I ended up buying a replacement part from the ebay listing I linked above for about double the price you paid for yours. It has yet to be delivered to me, it's still stuck at the office of exchange.

Digitizer is not the "standard" issue for some non-oneplus panels - display keeps black occasionally after waking up the device is. See my previous posting and the detailed discussion in the los-16 thread.
Crossing fingers your panel is not effected!

Would you mind linking the post again? IIRC you had it linked in your other post in this thread, but I can't seem to be able to find it anymore.

So far so good, I've been using it quite often since I got it back, never had any issues with it so far, I'm hoping it's gonna stay that way
Is it possible for me to check whether or not the display is 'a5' or 'a3'?

I've referenced to the los-16 thread. I have NOT linked single postings. You need to search yourself. Good friends toöd me: if I not want to feel like a search assistant I have to stop behaving like one.

Theorethically in sysfs (i.e.: grep panel_name /sys/devices/virtual/graphics/fb0/msm_fb_panel_info), but in this case it can't work. The oem panels in question show themselfs as a5 but support only the a3 dtsis... It's really worth searching the conversation in the los-16 thread.

It sure is, if only I knew which los-16 thread you're referring to, and if only the search function wasn't broken (for me at least) on xda ¯\_(ツ)_/¯
Thanks for the heads up though once again!
