hey guys
i'm running stock fw 5.1.1 gen, 16/2gb.Does anyone else notice that their touchscreen is just buggy? I am talking about things like scrolling and tapping a link from a list, for example. Sometimes the scroll or the tap will register incorrectly and usage can be erratic. i've noticed this especially while using whatsapp when i try to open one chat from main chat screen instead of opening the chat it just scrolls down
is this a common issue ? seems like a HW problem to me
Sounds similar to what I've experienced:
http://forum.xda-developers.com/2015-moto-g/help/touch-screen-fault-t3183555
.. I suspect it's a hardware problem like you, but I was able to reproduce the problem on two other handsets.
I have tried a couple screen protectors now... The screen on the Moto G seems very sensitive to them. If you have one installed, try removing it. The best response in a screen protector I have found is with tempered glass, and even then there is still a little bit of "error" in touches.
Not sure if this helps at all, just thought I would throw it out there.
I don't have screen protectors and I've noticed some degree of unresponsiveness, but only after the stagefright update. I've flashed the newer stock firmware (not OTA) and noticed the issue after using the phone for a few minutes.
I too have a tempered glass screen protector and from time to time I notice there are a few glitches.
Granted I applied it the same time when stage fright ota was released so who knows now.
I have this issue too and I am in the US. I don't remember if it happened before the stagefright patch. For me it is much worse when using swiftkey. The google keyboard does it very rarely on occasion. I do have issues that worry me somewhat with my touch screen though where sometimes when I swipe down it also swipes slightly to the right or left which doesn't happen on my old phone. Several times when my morning alarm is going off on my phone I will swipe in the direction of snooze which I had no issue doing on my old moto E but now on my new moto G the swipe to the left for snooze gets interpreted as a slight swipe to the right causing it to say alarm off instead of snooze. Luckily I noticed that so I didn't end up sleeping in. The moto g 2015 seems to have a much more sensitive touch screen than my old moto e 1st generation. I just hope this is a software issue that can be fixed and not some sort of hardware defect that would result in me having send the phone back and wait for replacement.

There are lots of videos showing this problem: after you have touched the screen sometimes the screen registers finger presses even after you've removed them.
It's very hard to see what is going on if you don't turn on "show touches" in settings, so I suspect many reports about touch screens being unresponsive, or acting strangely is really the same problem.
It occurs both in stock ROMs and aosp, but subjectively more often in stock roms. It's not about moisture remaining, I've wiped the screen completely clean and dry and the phantom touches are there before, during and after cleaning.
Is there a software solution to this or is it hardware? Any thoughts of how this problem could be approached? I'm having trouble even reproducing it reliably.
yet another video of the odd problem: https://www.dropbox.com/s/mglol5qon6vy67g/2013-08-11 20.15.01.mp4
I replaced my Asus TF300 because of a similar issue. Asus fixed it once under warranty (replaced the entire LCD and digitizer, I think) but the issue came right back within a few months after RMA. By then the warranty had expired. In my case, the ghost touches were prevalent in a specific part of the screen; couldn't tell from your video whether the false touches were in the same general area every time or not.
Surprisingly, until the problem became so bad that an entire area was unusable, I could flash a new ROM and get somewhat different behavior. Just to be sure, though, I did flash a stock ROM prior to sending back to Asus and verified the issue existed there, labeled the area with tape so they could not miss it, and described in details the steps to reproduce.
Good luck.

This is my experience also, the aosp revolt rom, seems to suffer much less so than the stock roms.
It does seem to be the same area but it might be just because it's the side that is used most often for scrolling due to me being right handed.
The difference between how the roms behave is what make me suspect it's a software issue.
Just to be clear, you've not noticed this even once with your note? Before I turned on the "show touches" I saw it most clearly when I used chrome or other programs with scrollable elements. The page would sometimes just vibrate a little when left alone.

No, my note has been rock solid, but I haven't enabled show touches so I can't say for sure.

I'm thinking it might be possible to alter the idc file that specifies the behaviour of the touchscreen (https://source.android.com/devices/tech/input/input-device-configuration-files.html). But it's all a bit over my head.
I'm not alone at least:

A simpler cause?

The guy in the video did a great job with research. Did you catch the part where he found nearly imperceptible damage to the screen that was a possible cause? The ghosting always seems to occur in the same places because that's where the screen has been "crushed". Now "crushed" is a bad word because the screen probably hasn't been compressed beyond an acceptable level but there might be some correlation between where the users normally places his/her hand when using the pen and where the phantom touches occur. Maybe when writing, some users are baring-down harder than they realize and prolonged pressure in the same arc-shaped area created by the side of a hand, causes some changes in the capacitive properties in that area which cause a "latch" condition -- where the digitizer gets stuck and won't unstick until power is removed.
I've noticed in the videos that I've seen that the presenter get the problem to appear when using the side of their hand in a rolling fashion -- probably the same motion that they use when they just start to write. I also believe that devices that have this problem "get better" or less sensitive when not used for a while. This would follow the idea that the screen is compressed and given some time, the compression relaxes.
If the problem is limited to a certain area of the screen, I find it hard to believe that the problem could possibly have anything to do with ROM or firmware. The matrix of the digitizer in X-Y coordinates is addressed such that if there were a problem like this, the error would occur and repeat in either a straight vertical or horizontal direction instead of finite points spanning many rows and columns.
I guess one way of ruling this idea out would be to find someone who has never used the pen to write yet still has the problem.
I haven't ruled out that it is hardware related, but I have noted a significant improvement leaving stock ROMs for aosp. Maybe that's just a coincidence, I can't know for sure. I have noted something else that might help diagnose this problem.
If the period of turning on the screen, using the tablet then turning off the screen constitutes one session, there are two types of sessions. Sessions which suffer from this problem, which will be apparent in a relative short period of time. But there are also sessions where everything works as it should, regardless of how long the session is. So you will notice this problem within 10 min or not at all.
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

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
Maybe this is the fix? anyone had this before?https://forums.oneplus.com/threads/...-hint-it-was-never-a-software-problem.186235/

Possibly. Mine had a very slight issue like this when the phone got warm, but that is mainly for people with the TRUE ghost touch. That means you swipe and sometimes it swipes lazy whrn scrolling because it didn't catch the entire swipe, typing on the keyboard is terrible because it "touched" a different letter, and using an app to test the multitouch registers less than 10 fingers, or even putting a few fingers on the screen causes it to touch elsewhere or not detect a touch. I had a OnePlus One like this when they were still being sold and it was terrible. Then there was a nightly CyanogenMod build that fixed the problem but would drain battery about twice as fast.
Currently, we have custom roms that have updated drivers which vastly improve the screen performance on the ones that had very little issues. Me for example after flashing DotOS I no longer get the very slight issues. My issue mainly occured when swiping, where it would require a swipe perfectly straight up or down instead of the normal way we swipe with our thumbs which is usually slightly tilted. It wasn't something to ruin the experience for me, but sometimes unlocking my phone with the pattern was difficult because of this. There was another rom out there that specifically outlined that it had many updated drivers including the Synaptics drivers (touch), but I cannot recall the name.

my oneplus one was fine bro, I used every custom rom and it worked very well! but in the last month it start happening this ghost touch problem
and I'm sure its 100% hardware, even on TWRP it happens
Hi all, I have been using a OnePlus 7 Pro since June and it's been going great for me.
However, recently I've noticed that if I press a bit harder (almost like a force touch) on the top middle-ish part of the display, I can hear a distinctive creaking, almost popping noise from the phone? This sound doesn't come from pressing harder on any other part of the display, just that middle area. It doesn't appear to be causing any problems so far, but I'm wondering if anyone else has experienced this with their device? Haven't found anything on the internet just yet...I'm worried that it'll become an actual problem later on.
I'm on stock OOS Android 10 Beta 4, but I don't believe this is a software issue (hopefully it's not). Side note though, I do notice that my device still suffers from ghost touches and is parts of the display are nonresponsive occasionally.
Thanks for the help!
I have the same popping on the upper middle of the phone ever since I got the phone in May. But, as you say, not causing any issues....yet. don't have ghost touches and non-responsiveness. I'm on Pie still.

Very weird...I wonder if this is a common issue or not; doesn't seem like it. I thought upgrading to Android 10 would fix the ghost touches (pretty sure I read something related to that somewhere before) but I guess not; almost seems like it added more ghost touches than before lol
mine is fine
I've been using this phone since it came out and I have nothing close to what you describe my screen is completely fine.
My OP9 is perfect apart from 1 thing. When scrolling, I keep my finger on the screen when I stop. When I resume scrolling after a second of the finger being still, there is a slight delay in responsiveness of the screen which resolves within a second. The bug does not occur in any other scenario.
I've figured out what the issue is using this app: https://play.google.com/store/apps/details?id=com.rt.touchmultitest
The touch sampling rate drops to around 50Hz when the finger is stationary on the screen, and doesn't reset to 240Hz fast enough when you start moving again...
Can anyone please test it to confirm?
TLDR: Touch sampling rate idles when finger doesn't move/moves a little.
Ive noticed issues but it was resolved when i removed the OEM screen protector that's preinstalled on the phone.
I also had to get a new OP9 (unrelated to removing said OEM screen protector) and I am now just dealing with the responsiveness issues until it starts losing its flush application to the screen and starts peeling.
Just a guess but people not realizing its there or just forgetting due to it being so easy to forget is a major reason they report touch responsiveness issues (happen to me when I first got the OP9 AND 6)
Maybe thats it?

It could be the screen protector, although I doubt it... It seems to occur in a very specific situation, almost like it's there intentionally.
Could you please replicate these steps:
1. Scroll on a website/text
2. Stop scrolling and keep your finger on the screen (important)
3. After a second of the finger being still, resume scrolling with a fast gesture (without moving the finger off the screen) and see if the screen follows with appropriate speed.
In my case, there is a noticable delay at first but it resolves after moving the finger for a while.
Can anyone please check if their phone behaves like this? Thanks a lot!
I have the exact same issue.
i have the same issue too
Nope , tried recreating, no issue here .
p.s. not using seen protectors .
Hey OP. I am on the Paranoid Android Alpha ROM and believe this will correct your issue. Its touch responsiveness feels completely different from stock for me and no longer have any issues.
If you are comfortable with any of that, maybe give it a try.

i cant find the article, but its a bug that was introduced by google even to the pixel lineup in android last year or year before. The same thing happens on the One Plus Nord N200. Its annoying. I beleive google fixed it but doesnt seem like one plus has fixed it or carried the fix from the google tree. In android 11 google also introduced touch sensitivity but seems like one plus removed it in their final release ROM/FIRMWARE https://www.xda-developers.com/google-pixel-4-new-increased-touch-sensitivity-option-android-11/
