I'm a first time poster. I have searched the Q&A section a few number of pages about my problem and I can't find anything.
My phone likes to press a certain area of the touch screen without me touching it at all. I don't really know what else to call it except "ghost inputing". Sometimes when I go to input text or when I'm at the home screen, it decides to go crazy. If I'm typing up a text message, if in portrait, my phone likes to type Q's even when I definitely don't want to. If I'm in landscape, a bunch of spaces and period is what it likes to press. If I'm at the home screen, the phone likes to pick up an app or open it.
It gets pretty annoying, especially when I'm just trying to reply to someones message. My only temporary way of fixing it was to turn on and off the screen. Sometimes it takes awhile.
I have tried flashing a stock 1.47 ota rom but it didn't really help, actually made it worse. Touch screen responsiveness dropped significantly, so i flashed back down to like 1.32 (responsiveness came back).
I got my phone the day it was released, so I don't even know if I can bring it back to Best Buy or not. Any kind of suggestion would be great... this problem can really bring my spirits down sometimes, especially when I'm showing off my phone to random people when they ask me. Kinda embarrassing to have my phone freak out when it's supposed to be a high end device....
Sounds like a warranty thing. I'd hit up htc.

Im having the same problem making my phone useless :/
I have been trying to bring this issue to light for sometime!!
I have a topic on it already if you guys want to add to it but the end result for me right now is trying to get the phone exchanged..

I have had the same problem.
Turning the screen on and off sometimes makes it go away. It seems like it started when I rooted (simple 3 click). Not positive about that though.
I'm now running Fresh 3.1.0.1 and it is better.

Try running some of the older ROM's not based off the .47 OTA or the newer froyo and its gone completely for me..
Problem summary
Known cause (might be others): selecting an app from the Recents list (Task Switcher)
Temporary fix: turn the screen off, then back on
Workaround: avoid using Recents list (you can use a 3rd party task switcher instead)
How to test: open Messaging, hit Home, hit Recents, select Messaging from the list. Your screen will be less sensitive until you turn the screen off and back on. You can view the pressure by going to Settings -> Developer Options -> turn on Pointer Location. This will allow you to see the Prs of each tap in your status bar. Normally your lightest taps that register will show anywhere from 0.28 to 0.32. However, after this bug is activated, you will mostly get values over 0.40 for your light taps. This is actually a very noticeable increase, especially when trying to type quickly.
Please report any other known methods to "activate" this bug. After re-assigning my Recents button to a 3rd party app (I'm using Simple Task Switcher), I haven't seen this bug at all. It seems that a couple of people have seen it produced by something other than Recents, but they haven't narrowed it down (or reliably reproduced it on purpose).
Please star this issue officially so Google can fix:

Been using my screen for almost hour straight now. No issues.

Hehe yes this s gonna be a difficult one to confirm. But it is definitely not dirty hands. To clarify, a quick press of the power button to lock then unlock completely fixes the issue. Same fingers suddenly register perfectly. This is driving me nuts as the phone is not even usable right now. Literally.

ios 6.2 doesnt get issues.
I don't know about your other experiences, but as far as the browser goes I have the same scrolling effects as you do. I think this is how it is meant to be. They tightened the scrolling a lot and I kinda like it. Before one small flick would send me across the whole page, which was kinda annoying. Just my preference.
I'm not having this problem. It would drive me crazy too. Been using my phone alot over the past two days and I didn't run into this problem even after almost 1h of continuous surfing. Also a few checkpoints of Shadowgun didn't trigger it.
But you can confirm your problem if you enable "cursor position" in the dev options (hope that's what it 's called in english). "Prs" and "Size" should need a lot more than around 0.30-0.40 to register your touch if you have the problem you describe.
I am sorry that you're experiencing this, but 4.0.4 has nothing to do with this. 4.0.4 is just software, Galaxy Nexus is not a pressure-sensitive device, it is merely touch-sensitive. Which means that software gets an analogue signal from the touchscreen, either 1 or 0. It has no 'range' of sensitivity, so it cannot decrease in sensitivity in software (if it did, then it would not work at all).
This is entirely hardware issue and I suggest either making sure your screen is clean, your screen protection thing (if you use one) isn't acting up or if your hardware has become faulty (have you dropped it recently?).
If problem persists then return under warranty.
My wife had this issue once.
It was the third party launcher she was using.
I don't think its a matter of touch sensitivity dropping, its a matter of the system just being too slow to really work right.
It was ADW EX, fwiw.

Lol that is hilarious. You forgot the step where its the OS that actually processes the input data, so in that process, a ton of problems can arise.
And personally, since 4.0.4 I have also been experiencing a "similar" issue. When scrolling down (and only down), I experience a kind of "lag" like if it only registers the swipe movement half an inch lower. Its not a big deal, but still an issue.
Edit : What he explains as "pressing very hard" is most likely the fact that when you press harder you actually cover more surface, so the amount of extra input data can definitely impact the behavior.
I had issues for a few hours after the 4.0.4 update, where my softkey buttons weren't responding. Thankfully, it seems to be fine now, but it was a cause for concern.

Thank you my friend, I should have thought of this; now I have numbers to confirm this. So with cursor option enabled I can get down to 0.30, managed 0.28 once. However when the bug starts, I can confirm that I cannot get below 0.60. It just refuses to register that input for some reason.
I lock the screen, 1 second is all it takes, and now it registers down to 0.30 again and all touch works properly. Its almost like some type of memory leak issue is the way it feels to me. It only starts happening after a few min of use.
Its definitely an issue now that I can see the pressure numbers. The question is what the hell can I do about it. I flashed aokp29 with the latest 4.0.4 ota merged in, problem still occurs. I'm gonna try stock 4.0.2 or 4.0.1 just to see. Thanks.
I have never had much luck upgrading Linux versions. That's why I start fresh every time with Android. Lol

Before I start digging, anyone know specifically which driver controls the touch input? I'll try looking thru github.
Also I was on stock 4.0.1 prior to this. So this could be normal behavior for everyone but everybody is used to it since nobody stayed on 4.0.1 like me. Cause I can easily say this is difficult to notice if you aren't paying attention. The question is, why does locking the screen temporarily change it back...
I can confirm some of what you are saying..sometimes when I'm browsing the scrolling tightens up..I lock the phone then unlock it and it is smooth again..doesn't happen all the time tho..doesn't bother me but I've noticed it

I can also confirm. This morning I found the Swiftkey was lagging on Facebook. Something like the phone did not receive the touch. Then I rebooted and now it is ok.
I did not get this issue on 4.0.2 and I don't install anything new on 4.0.4.
The way I installed 4.0.4 was from the official factory image, so my phone is fresh! I reinstalled all apps manually as well. Nothing fancy apps.
I know this is my first post, but I can definitely confirm this issue.
I use my Galaxy Nexus for development, so the screen is always on. The sensitivity goes down very quickly.
My phone was an International GNEX that I loaded the US firmware on and then I flashed the OTA 4.0.4 update.

Just to point out, the phone is all digital. It does not get an analog signal from touching the screen. Also to that point you said analog but then described digital with the 1 and 0
Has anyone affected tried going between 4.0.2 and 4.0.4? To check the possibility of a driver or some related value changing.
Also, if not fixed by going back to 4.0.2, this could be due to current leakage from somewhere causing the touch to not work properly. I've seen it on other capacitive touch devices, though mainly when a non-compatible charger is connected. When you shut the screen off, the charge causing the problem/interference with the touch is temporarily dissapated, but then comes back after you use it again. Probably very unlikely in this case, unless Google changed something in the touch driver that makes it more sensitive to interference, which in turn messes with actual input from fingers.

Its possible. I was on 4.0.1 so perhaps this issue originated in 4.0.2 but I never noticed since I didn't update then. I can add that I did multiple wipes and clean flashes, and also tried both aokp 28 and 29 (new 4.0.4 ota merged), and happened on both.
I'll post what I just sent to arbiter which gives more insight.
From my extra testing under normal use my light touches register 0.28-0.33. Especially on swipes, the end of the swipe registers 0.28 as the finger travel breaks contact with the screen giving that swipe extra input which pushes the swipe motion further extra boost. When the bug starts the touch swipe won't even break 0.38-0.40, and that extra swipe data is lost resulting in the end of the swipe data points being excluded and swipes travel half the distance.
This gets exacerbated on the keyboard when fast typing light pressed. Its so bad it frustrates my face off cause typing just ceases to be possible. Such a difficult issue to diagnose.

Yes my face literally flew off!
Does anyone's S6 edge have this problem where you are typing a text, at least 10 words long or more, and the screen don't recognize touch input just once, but it happens every 15 to 20 words? Its freaking annoying and I've since switched to the google keyboard and this problem don't happen as much, but the problem is still there, its caused me to misspell at least 7 words so far that the keyboard has auto corrected. This is so damn annoying and I hope I'm the only one that has this problem that way I can take this phone back and get it replaced.
I guess I'm the only one
Happens to me sometimes, but not all the time. It's probably a RAM problem. I usually clean/close some opened apps with Cleanmaster to prevent lag. Hope the next update will fix memory management problem.
I'm on Android 5.1.1 and it supposedly has fixed the RAM issue and the problem still exists. I don't think it's a RAM issue. I think it's a software issue that when you type too fast it stops recognizing the presses. Hapes mainly with the backspace key. If I tap that button like 20 times it will stop pressing it no matter how hard I press.
I want to say this is a Edge thing not a S6 thing.
Try a different keyboard from play store, also try closing apps in background.
I haven't noticed the ever on this incredible phone.
Running stock no root yet, with 3 pages of apps disabled.
Pp.
I apologize for resurrecting this thread but, I've been searching for a while with no avail. Since I've upgraded to 5.1.1 I've been experiencing this issue. Has anyone in the time of this thread found a possible fix for this?
I've tried multiple things, maybe going to have to resort to cleaning up with a factory reset.
This phone is so beautiful, yet functions like a POS, minus the camera. It just sits on desk collecting dust. I too have the aforementioned issue, along with dozens of others. First phone I've ever regretted buying.
Is anyone else having issues with what appears to be dead areas when scrolling, swipe texting or otherwise using your phone? In typing this message the phone just lost my finger on 4 occasions. When scrolling webpages it often just stops and clicks an area where my finger was. I'll get occasional double clicking on things when I do try to click. I have trouble purposely replicating my problems but in regular us it is driving me nuts. Because I can't constantly replicate I'm not sure trying to take the phone back will be successful. Anyone else having issues? Could there be something I'm missing somewhere?
Sounds kind of mean but I hope your issue is isolated. I saw the ifixit teardown and the ease with how the digitizer came off of the glass has me worried about the longevity of the digitizer.
Happening to me insanely often on my regular Pixel.
This happens to me occasionally. Sometimes, when typing it spams v and b. If I find anything I will fill you in.
Yes, I'm having this problem with my Pixel. It happens across all apps, even in Settings. Generally it happens if I start scrolling after not touching the screen for a little while.. for example when reading a news article. The scrolling freezes, and I can move my finger around on the screen and it doesn't react, but then it might pick up my finger again and the screen jumps around or clicks on something even though I've not lifted my finger from the screen. I tested it in safe mode and it happens there also. I even got my original device exchanged, and the same thing happened immediately on the new phone. I've been in touch with Google Help this morning and they've confirmed it's a software issue. They've asked me to submit a bug report. It'll help them if more people report the bug though and they have more data to fix it, so if you're experiencing the same issue, please report it! You can chat directly to Google support through settings on your Pixel.
Haven't had any issues but I know the google keyboard can be a bit glitchy at times. I used to have a nexus 6P and I would get weird issues with that keyboard as well on that phone. Getting them less on my Pixel though.
Having issues with typing on my 6P, it's so odd as sometimes I can not type when in desktop mode and sometimes not when in mobile. Switching the webpage screen mode and also doing a soft shut off on the phone and coming back both fix it temporarily. Thought at first using a different keyboard app might help but what app it runs does not solve the problem.
Same problem here. Google pixel
Happening to me as well. Did a factory image flash and it seems to have helped but still happens once in a while. I notice it the most when I'm using reddit sync. Seems to just happen too frequently.
Just an update on this... After doing a few steps suggested by google tech support like, test on safe mode, factory reset using bootloader method, etc... They just replaced my unit. I'm using a new one today and problem is not existent now. I would assume the problem would be hardware.
To be honest, I'm quite happy with their tech support...24/7 support and the staff are really competent. This in my opinion, is worth the high price of the pixel. Good job google!
I have the standard Pixel, and I too had issues with typing (occasionally wrong letters or spaces would register), and dead areas in the top corners of my screen when trying to open apps. I was going to return it one day after confirming that the dead areas at the top of the screen were persistent, but for some reason I decided to grab an App from the bottom of the screen and move it by sliding to the top area. Instantly this cured the dead area issue, even after I moved the app back to the bottom of the screen. It's as if it recalibrated the touch sensitivity vertically as it stopped erroneous spaces when typing too.
Pixel 2 one handed thumb scrolling issue
I have the pixel 2 and I have intermittent scrolling issues when I hold it one handed and try to scroll with my thumb. I realized it's because the base of my thumb is brushing the opposite side of the screen and preventing it from scrolling freely.

You should probably post about that in the Pixel 2 forums.
Been using the phone for the last 12 hours and I noticed something towards the end of my use last night.
The screen seemed to become unresponsive. And when it would work it would start to make its own input when scrolling and opening any app or link my finger would drag over while scrolling.
Changed refresh rates, changed resolutions, even seen if the blue light filter was the issue. Nothing.
Almost seems like the screen drops frames when scrolling, like it gets caught on something.
New development. Fingerprint sensor doesn't respond at all and inputting a pattern is damn near impossible. Going to try removing the screen protector to see if that could also be the issue
Did a factory reset
Issue seems to be where the finger print scanner is
It's almost like a dead or unresponsive zone.
Sounds like a factory defect, better have it replaced if resetting didn't worked.
Small video showing when scrolling over the fingerprint reader, the screen almost loses input
Defect.
Samsung has been little help lol. They want me to send it in for repair instead of an exchange. They also said to just order a whole new one and return the one I have now except the black 128 is sold out

one of the first things i did to trouble shoot. still having the issue. sometimes the screen completely loses all touch registration and it doesnt even know im trying to swipe or push on things. just realized it did this also after tmobiles new software update.
im still waiting here to hear back from samsung on how they are going to fix this issue
The same thing happens to me. Pulling down the notification shade seems to be the only thing that still works. It seems to goose the phone and it starts working again.
Test using the *#0*# diagnostic menu and use the Touch test.
