My nexus s at times tends to be unresponsive at the center part of the screen. This problem has actually plague me from since I was in stock 2.3.1 and followed on up to now. From my searches, I know I'm not the only one that has this problem and some speculate that having a screen protector contributes to this problem.
My best bet is that this would be more of a software problem than a hardware side as a quick lock/unlock always fixes this issue. Below is a request by someone in cyanogenmod and I find that his response seems to have some good basis. I was hoping with a better background in developing this stuff could help. Also what to know who else out there is experiencing the same problem.
Recently I've got a Nexus S, and I fount its touchscreen sometimes unresponsive, especially right after unlock. The center of the screen cannot sense tapping, but the edge and corner area works well. The four soft keys always works great, but I think they are controlled by a different cypress chip. I've tried to connect adb and "cat /dev/input/event0" and the result confirms my observation. Searching a Chinese android-lover forum, I found several guys are experiencing similar problem. (Some are running stock, others, including me runs CM-7rc). The problem can be strangely solved by locking and unlocking the phone quickly, and when the touchscreen is working correctly, it's actually very sensitive and responsive.
Suspecting a driver issue, I looked into the source of touchscreen controller (AMTEL MXT224) driver (/driver/input/mxt224.c) by Samsung and compared it to drivers of the same chip by Motorola and HTC. I notice that HTC and Moto's drivers send calibrate signals to the touchscreen controller in there resume method, but samsung's does not. I doubt whether it's the cause of issue. Modifying driver and compiling android kernel are beyond my knowledge, so I'm calling for help.
I know not all nexus s are suffering this, so I'm read to test and provide feedback. Any help would be greatly appreciated!

I blamed OnePlus for months for not doing anything for the annoying problem related to the touchscreen panel in a lot of models of the OPO. I was sure it was an hardware problem and only a RMA could have done something for me. I couldn't return my phone cause i always need it and i didn't have alternative phones to use. So i just gave up, living with some not-extremely-frustrating-unresponsiveness during fast typing.
But...
After installing the last official CM11S update (the 05Q one), i noticed some strange responsiveness during a chat with a friend. I was curious, so i reinstalled YAMTT for some test. I couldn't believe that all my inputs were perfect even at fast speed. I still don't know if it was a software or hardware issue, but OnePlus seems to have finally fixed my situation.
Looking for your experience after the update.

Not yet they aren't. It appears to have affected the functionality of double tap to wake for some people.
Doesn't seem like they're updating us on the investigation either. If they've fixed it using software, at the very least they should tell affected users why all the previous updates didn't work for them.
I've been on the nightly road since mid August, in my experience touch issue improved a lot after the touch firmware update in October, however there are still very rare cases where finicky / unresponsive touch happens, you don't want that when you ask someone for her contact in a bar on Halloween and she can't input the letter 'n'.
After that I think I experienced touch issue twice, I foolishly thought this was fixed sometime ago, however it came back big time the day before yesterday, and I was on the latest nightly... So in short, touch issue is not gone
touch issue
even im having touch issues with double tap and typing.
Touch screen seems less responsive since this update

Do you guys have any problems with vertical scrolling (i.e. in lists, webpages etc.)?
I'm thinking about downgrading... I'm currently running CM12 nightlies and the touchscreen is annoying me

this is hopeless, I just went and looked at touch firmware updates, last ones are 1221 at the end of october and 1222 around new years, I remember it working ok during that time, and some time after that, how come I am experience severe touch issue these couple days, touch turned into swipes, swipes registered as touches, unresponsible parts on the screen. I am almost beginning to think it's about the weather/temperature, problems are more frequent when I am out hiking for a long time.
although somebody mentioned that last change was having problems days after http://review.cyanogenmod.org/#/c/83558/

There are at least two different touchscreen issues as far as we know:
One is where the touchscreen is semi-terrible all the time regardless of temperature
The other is where the touchscreen becomes unresponsive with the increase in temperature, and subsides if the phone is restarted or cools down
Is there a way of finding out which firmware is being used for colorOS?
I can't take this anymore, I am considering flashing either 44s or color OS
I've noticed a lot of people complaining about screen lag recently, where everythings just dull and slow (not so much touch issues)- and unfortunately im one off them people!
My phone is the newer branch (november) and im starting to have a slow screen ever since oxygen! i've gone stock 11s n its seem to followed me!
but i really think its heat related, it will be fine for the most part, once it starts getting warm (recently its been getting hotter then normal) the screen goes dull.
THIS IS NOT GHOST TOUCH.
my screen doesnt press random things, the phone is just dull to type on and stuff but only when its hot/warm, and when i say hot, i mean hot..
but im not doing anything different to what i used to and it used to be okay, but then again........weathers getting hotter....
my nexus 4 was horrible when warm also......
currently on cm12 nightly, 06.04.15
tried stock 11s too but only lasted a few hours
If anybodys noticed this PLEASE say something, also if this issue is because my phone is 'defective', will i be able to send it to oneplus for a repair? wil it be worth it? will it be free? how long will it take (*roughly*)
sorry for all the questions and blabber, it's just i've been wondering A LOT and ive not been getting straight answers.
Ps. NEVER had issues BEFORE oxygen. oxygen was NOT on my phone for longer than a day due to the horrible keyboard issues, but the phone was really hot during oxygen......... thanks anyway, :good:
I have the same problem. It seems to happen when my phone has been warm-hot for 15-20 minutes. No ghost touches, but scrolling is really laggy, and sometimes it doesn't register a tap on a link or app. It seems to go away if I let my phone cool down. I've looked everywhere online, and I've seen a few people mention similar problems, but most of the time it's about the ghost touch thing. I really hope it's not a hardware issue. I can't go without a phone for a month and a half for the RMA. People seem to have a lot of issues with RMAs. I'm surprised there aren't more people having this issue.
Also, I'm not on oxygen. I'm having the issue on Euphoria 5.0.2.
I started having the exact same issue two weeks ago, and I did not even try oxygen os. I also bought the phone in november. I tried opening the phone and cleaning the connector but it didn't help at all... now I'm having the issue all the time, not only when the phone is hot and it feels like I have a $30 phone
I really don't know what to do since I opened the phone,so no RMA possible. I bought a Moto E and I'm gonna have to use it until I fix the issue. I dont even know if it's software or hardware, that's a really strange issue.
Edit : the touch screen just worked fine for 2 minutes, then became laggy again
A few people here and there have been starting to have this problem pop up- including me.
My phone was perfectly fine with absolutely no problems with the touch screen but about three days ago, my phone started acting weird.
At that time, I was running CM 5.1 nightly and then dirty flashed over to the latest. I thought that this was the problem and so I did a clean flash but still the problem was there.
Went back to the original CM nightly that I was previously on and problem is still there.
Tried many different ROMs but the problem is still there..
I can't type out a sentence without my phone failing to register a touch and sometimes registering rapid touches as one - the same problems before Synaptic released a 'fix' for this issue.
At this point, I don't really know what to do but it's aggravating that a phone can't do it's basic tasks such as type.
The phone seems really sluggish when I type - which I haven't encountered before this which slightly leads me to believe that input lag is the crux of the problem however, I can't say for certain.
Can anyone with more expertise help me with this?

Im having a similar problem. I cant type a single sentence without errors. It doesnt register the touch as well few times. Using a device is so sluggish.. hate it. Tried many roms with clean wipe but without any success. Would be nice if anyone could help with the above issues.
I have similar issues and I don't think it's a software issue - I have never flashed a ROM. I think it's hardware problem, probable the earthing suggested in this post:
http://forum.xda-developers.com/oneplus-one/general/fixing-ghost-touch-grounding-issue-hint-t2951000
There is an app that re-calibrates the touchscreen every time you turn it on, but it doesn't completely solve the problem for me and also prevents unlocking until it has completed, which is annoying. The fact that a re-calibration is needed to even achieve a little stability is consistent with an earthing problem.
If mine gets any worse, and I think it will, I'm going to investigate a warranty claim, but that sounds like a few weeks with no phone, which I can't tolerate.
hi, i'm experiencing the same problems. you can test this when registering 2 touches on the same Y axis (try with anyone of touch test apps).
I think that this is popping out to a lot of people in this moment because of the hot days kicking in. in fact, if your phone is cold (try to put in a fridge for 5 minutes) it will work perfectly, but when it will become hot again in your hands the touch will start to freak out again
What sucks is my phone was perfectly fine a few days ago and we've only had an increase of about 5 deg F over the week.
Occasionally the capacitive buttons don't register either.
Same thing here. Perfectly working screen, flashed 5.1 unofficial some weeks ago and no matter wich versión of cm or what kernel, randomly ghost touches happens.
Now with official 5.1 and ak 200 works better, but it's still there. There must be some kind of firmware/software problem, It's too curious that this issue begin to happend to many people at the same time.
My bro has the same problem, some days after flasing CM12S the screen doesn't feel as responsive anymore.
The screen isn't able to handle multiple touches anymore what makes typing really annoying, scrolling through settings also goes really slow.
Tried flashing latest 12.1 nightly but I don't think any ROM will be able to fix it.
No idea what caused it and if there is a way to fix it.

This is exactly what happened to me and it seems like it happened to a good number of people around the same time. Either 1)It's a huge coincidence 2)OnePlus rigged our phones to go haywire around this time or 3)Something in one of the nightlys got messed up for a few people however like you said, flashing new roms for kernels doesn't help anymore which makes me want to do a complete wipe - Internal data included.
Same issue
I was sure it's the heat some time back but then this touchscreen fixer app in the Themes and Apps section is actually helping. That makes me wonder if its the firmware, coz the problem only kicked off after the CM12.1 update. A few of my classmates purchased the OPO at the same time as I did and they dont have this issue (they didnt go to CM12.1).
Any tips on what firmware/ROM to revert to?
Edit: I also flashed the Oxygen OS firmware.
It's not a change in the firmware, mine did it spontaneously. It's hardware. OnePlus will do everything they can to spin a software story and indeed it will often be possible to partially mitigate in software, but ultimately everyone with this problem should be getting a replacement. That could be a lot of people.

I'd love to see how you jumped to such a definite conclusion. I live in a warm climate to begin with, temperatures are actually lower now than they were a month and a half ago, and the CPU of my OPO has definitely risen above the 41-45 Celcius range that people seem to quote for this current wave of issues (and I have corroborated with my own testing). However, if I go to the recovery, the touchscreen seems to have normal responsiveness, regardless of the CPU temperature. Unless it was a built in hardware malfunction set for a specific moment, the probability of a sample, even of this size, where a series of individuals can all see the exact same lineup of hardware-based issues occurring at the same time, is too ugly for me to try and imagine calculating. But I would fare to bet it isn't high.
However, if a set of users are all changing their software as new versions and builds come out, just as the release occurs... At least then you have a series of events occurring all at the same time. Not causation, but at least there's a stronger correlation than "it's warming up so now we see the hardware defects".
The temperature range this "defect" is being attributed to can be reached quite easily in normal use in temperate areas, but even in colder climates, it should be simple to reach such temperatures if the phone isn't underclocked, as the phone is set to charge, or even if the phone is running a software update of some kind, and countless other things.
TL;DR - Don't jump to conclusions that fast, weather changes aren't a strong correlation.

The outside temperature being warm would keep the screen hot for a prolonged period of time as compared to the phone heating while charging or intense usage. However, your recovery argument is spot on! The touch works flawlessly in recovery!

Well I guess it's good that it's not hardware damage.
Has anyone tried going back to android 4.x to see if it helps- if it really is software?
Surprised there hasn't been more people experiencing this issue given the number of people going to android 5.x
I have the same frustrating issue
Same here, works fine in recovery. Also had this issue arise after the first bout of touch issues: https://www.youtube.com/watch?v=yoFYcFawTI4&feature=youtu.be
(clearing cache seems to alleviate that particular problem)
I think it's a software issue. I mean possibly there is hardware problems too but mine started appearing only after I installed the 5.1 update... also some things for me feel like a software issue for example when scrolling instagram back up to the top. as soon as it gets to the top it bounces back down again.. seems like software problem to me.
This is definitely a hardware issue. My phone was working perfectly. Until I went on a 5 days trip and used it for navigation, and went very hot. Up until then I was on the same CM12 rom for weeks without a problem. Since then, I've flashed many roms and the problem persists. It's definitely a hardware problem. For me it occurs whenever the phone runs a little bit hot. Practically all the time when I'm on 3G. When the phone has been in my pocket with 3G on, it's almost impossible to unlock it when I try to use it.
I contacted Oneplus a week ago and I still try to get them to RMA the phone. They've sent me all sorts of crap emails, I wiped the phone and now they ask me to shoot a video to showcase the problem. This company has the worst customer service you can find. As much as I like the pricing, I won't be bothered again with their devices. I only hope they'll RMA it otherwise I'll open it myself and try to fix the grounding issue. There is a detailed how to which also explains what's the problem.
I always had it but it was so minim that maybe couple of times a day weren't that big problem!
Just yesterday and today the issue is now intolerable! I removed the screen protector and used the stock lollipop keyboard (bcz swiftkey is kinda slower the issue was there more).
It's still very annoying and I can't type easily! I had to remove flow/swype feature to minimize it further!
Seriously considering buying another phone although I wanted to keep it for a year at least! But the hate is growing on me...
HAha exact same problem here happening since 3days.
I was on Euphoria 29/3 build. I flashed ak kernel, after reboot i couldn't type properly anymore. I was like damn, maybe its bad kernel setting or so. Didn't help.
Cleanflashed 3 roms since then, didn't solve anything. All tho touch works fine in twrp for me. So im really clueless. Swiping does seem to work better for some unknown reason to me!
The ghost swipes while typing is driving me crazy. Thinking of going back to 5.0.2 to see if that helps. Do I need to flash an old firmware to go back to a previous Android version
