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.

[Q] Touchscreen problem: "Phantom" touches

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:

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.

Touchscreen sensitivity issue

Hi there guys,
I've been researching on this problem i've got with my Oneplus. It seems that the touchscreen is'nt responsive enough.
Often when i'm scrolling trough (for example) facebook, the phone has a hard time recognizing my swipes, and picks up regular touches instead. Which is causing me to open or like posts when i'm just trying to scroll trough. If i'm scrolling trough my homescreens while just slightly touching the screen, it acts up really hard.
The screen just isn't responsive enough imo.
I'm wondering if other people got the same issue, and if it is hardware or software related.

Funny. I have my oneplus one since a week ago more or less and i also noticed this issue in the very first days of use. Now i've opened facebook app to make some scrolling and see if the problem is still there and i have to say that i don't notice it anymore. Strange, but this is what i feel O_O

Hmm, maybe you just got used to press a bit harder onto the screen (which helps). Would be great if it's really disapearing after a while
Got mine for 3 days now.

I have the exact same issue with my OnePlus after 3 weeks of use. At first it was the swype issue where the phone wasn't picking up swypes properly on the middle left side of my screen. I use a pattern unlock so it's annoying when the dots don't connect.
The next thing was not picking up my touches properly so when ever I use SwiftKey and they recommend words, I could never properly select it because the touchscreen wasn't registering properly.
I did a factory reset and it solved the problem at first but it's now back after 2 days. It's not as bad as before but still persistent. There are tons of people on Redit, Cyanogen and the OnePlus forums that are reporting the same problem.
The good news is it seems like a software and not hardware issue, hopefully the permanent fix can come soon.
Possible solution to the supposed OnePlus One touch sensitivity problem
Settings→Developer Options→ Scroll About Half Way and UNcheck "block gesture touch events"
Also try and see if unchecking "Adaptive backlight" in Settings→Display & lights→ Adaptive backlight, helps.
Of course none of these are permanent solutions. And this problem is real. But maybe the "solutions" above help.
ive not had these issues just yet. but i do get annoyed by gesture control
This still needs to be addressed. It's almost as bad as an old capacitive touch screen!
I got my phone maybe a month after it was released. After exactly 4 months the touchscreen input died and lost all sensitivity. Typing became impossible. After going back and fourth with support for 2 months they finally sent me another one. The new one was excellent for EXACTLY FOUR MONTHS!! Almost to the DAY! My damn touch is broken again and I can't type. I'm furious! I'm also 1wk outside warranty.
With the first phone I tried every hack, crack, rom, reformat, anything I could find. Nothing would restore the touch. I assume it's a hardware issue. I've been looking around for a solution but haven't found anything. If there is anything, I would appreciate some direction.
Sorry for everyone that ever wasted their money on OnePlus, I won't be getting any more products from them...

Touchscreen issues are finally gone?

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

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

Possible input lag/ Ghost Touches once 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

Question OnePlus 9 touch issue

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/
