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:

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.

I sometimes experience this. The bottom speaker stops working until I reboot the phone. I am investigating to find a correlation with some apps I use, yet this should not happen. Anybody else experiencing this?

Is the phone modded or stock? If modded, what custom ROM? Did you do a clean install?
Stock Sense rooted (unlocked bootloader + installed SuperSU). No other mods except for swipe to sleep.
EDIT: I say the bottom speaker stays silent "until I reboot the phone", but actually I reboot it as soon as I notice this, maybe if I waited some more time the problem would disappear without a reboot. I believe this only happened to me twice or three times at most so far.
Confirmed using Chrome
I encountered this issue and was able to narrow it down to an issue with Chrome(34.0.1847.114).
After visiting certain webpages I noticed the following issues:
1. When adjusting the volume the device shows that I am adjusting the “In-Call” volume.
2. No audio comes out of the bottom speaker.
3. The top speaker level is very low.
4. Wired headset will play at the previous level and it cannot be adjusted.
Here is a site that you can try that will put the device in this mode 100%: sci2.tv Go to the site, select home and you will notice all of the symptoms listed above. Go back to Chrome and close that page and the issues will clear up. Opening this link with other browsers does not create this issue. It also happens on the GS5.
Chrome 35.0.1916.122 fixes this problem.

Hi,
So I got an HTC One M8 when it first came out, loved it right from the start. However, since the start, I've been having various software issues. The gesture controls never really worked for me, the on board music player app never really worked for me either (to be fair, I think that's because my SD card is dying)...however, the biggest annoyance I've been having is that the default text messenger app randomly opens.
By that I mean, I can be doing something on my home screen, tapping away in an area that has nothing to do with where my messenger app is, and all of a sudden I'll be in my last text conversation.
I have sent my phone out for repair once and they re-flashed it. The problem persists after that.
Any suggestions?

Does it do that with just the messenger? I mean... The area on the phone where the messenger app is, have you noticed at all while in another program or something that that area gets "tapped". If not then we can probably exclude a hardware related issue kinda like a "stuck button" on the touch pad.

better yet check to see if it "draws" on the line test.
*#*#3424#*#* It should give you a screen with "HTC Function Test" at the top, press accept, select Line Drawing test and press on Run. Touch the screen once and wait for it to tell you to start drawing, just leave it then and see if it makes marks on the screen or not.
Just to check if maybe it's an issue with touch pad.

It might be a hardware problem then I don't think there's much that we can do on this side. I find it funny and odd that the service center you took it too didn't run these kinds of tests themselves and just instead decided to "reflash" (If they even did that).
Hopefully though the problem is software related somehow and perhaps a complete restore would fix it, but we'll see.

Have you got any mods going? Xposed for example? Something might be on like swipe up/down/left/right to launch an app etc. Must be something like that or it wouldn't only do it on the home screen.

No mods, Only thing in terms of swipe commands I have running are the default HTC Gesture commands which launch things like the camera. They don't open any of the apps that have been acting up.
Hi,
I have a UK sim free model. It sometimes misinterprets a tap or adds a phantom tap. Its not terrible but I'm sure mine has a issue. A quick Google and a tweet tell me I am not alone. Anyone else seeing this? I could return but I'm dubious it's hardware related...just not sure if it's worth waiting for a software update...

I have same issues with my g4 here in the US.
Unfortunately same here, on a G4, korean model F500S.
I have the same issues on my G4. So probably returning it won't solve it. I notice it the most when I am scrolling in Facebook or web pages I will open a link accidently.
I have the same, occasionally it just won't respond to some taps, i find just pressing the standby on/off button quickly sorts it but it is very annoying.
same here in israel, sometimes do not respond to double tap on lock screen to wake the G4 up
im sure its a software issue, prolly the LP 5.1

I am using the out-of-the-box protector on G4. So the thing u mentioned was it with this kinda protector or after-market glass protector?
Try...SGS Touchscreen Booster - Google Play Store
I have run into this same problem with my Verizon G4 (VS986). Many of my taps have gone unrecognized.
I did find this.... http://forum.xda-developers.com/g4/help/fix-touch-screen-registering-touches-t3128518

Okay, I was able to replicate my bug. It happens after playing a game and stops after some time. Turning autorotate back on and switching back and forth from landscape view fixed it.
Hey guys.
I was searching the forums for a fix that solves the phantom/ghost touches I'm getting frequently on my LG G4, H815 model.
Sorry for the long post but my case looks a little more complex than the ones I've been seen in here.
In my case, that's how it happens:
I receive several multi-touches at the same time, usually when Data is enabled. Sometimes it starts right when I switch from Wi-Fi.
It happens often when I'm driving and using Location+Data as well, which drives me crazy. I does also happens (like another user mentioned in this thread) when scrolling down a feed (such as on Facebook) and it suddenly likes/shares a photo/post. It also drives me crazy! And there is also the case where it taps the keyboard and send crazy typos on chat apps when you are real-time texting someone! Another hassle is right after using the camera and opening the gallery to show someone the taken photo...it suddenly scrolls the gallery and open another photo. I just can't make it to see the taken pic. Therefore, I really wanna fix this so bad since it happens every time I need something right away.
A workaround that's been helping, though it's a pain:
I found that pressing the On/Off button and giving it a few seconds will return it to a normal state. The problem is when it happens while I'm driving and are supposed to take an exit/make a turn at the moment. There are some other cases where I'm into something and giving this few seconds is not an option.
Trying right now:
Someone suggested in this thread to use the SGS Touchscreen Booster. I'm giving it a try right now.
Important notes:
This issue has been happening since I got this phone on November, 2015. We got this 6.0 update recently and I was hoping that it would fix it. It didn't.
I have an after market screen protector that I applied in order to see if the issue would go away. It also didn't.
I have been searching about a digitizer replacement but I don't think is a hardware issue, since it just doesn't happens when I'm only on Wifi at home with Data disabled. I believe that the problem is the Data connection that triggers smth.
Any thoughts?
Does anyone have any idea or have experienced the same scenario before? Any thoughts on my guess of data enabling triggering the ghost touches?
Sorry for the long post and thank you so much for reading it.
I think it's both, its hardware and software, LG tried to fixed it but it makes it worst. You can solve the problem for few seconds putting your five fingers at the home menu, It goes crazy and after it stopped making ****. Anyway this phone is great but all the problems make it ****.
I am going to use this thread even though I think my problem is not as serious as yours are.
My problem is that touches are registered, but no action is taken.
For example. Quickly tapping on an icon on the home screen will highlight it, but it will not open the application. I enabled the option in Developer mode to display the touches and the touch is registered. It's just that the app will not load. If I click for a tad longer - it loads. Happens on both stock Launcher and Action Launcher. I have not noticed it happening outside the launcher.
I read something about a keyboard update, but in the Update Center I don't have anything related to the keyboard.
The icons I see it happening with are located in the lower part of the screen.
I am almost sure that this is a software problem, but several updates have not fixed it. Currently on v20d.
Any suggestions or ideas?
After a few more testing and monitoring, I found out that the ghost touches only take place when I'm on LTE.
And even more weird, while driving through some specific areas when I'm commuting.
It's just so weird to think that some towers may send a LTE signal that may cause the ghost touches.
At home, at work, wifi or data, it doesn't happen.
Okay this has bugged the heck out of me for ages, maybe someone knows the answer to it.
The top notification bar (and sometimes the row underneath in certain apps) sometimes is completely unpressable, as if it's being blocked. I should note this happens on my Note 7, but has also occurred on my Note 3, my old S2 and even the S7. Which makes me think it must be a setting I choose, or an app I install.
Sometimes, I'll turn on my phone, go past the lock screen and I won't be able to drag the notification bar down. I found a workaround (which has worked on all my old phones).
- Turn the phone off
- Turn it back on
- On the lock screen try to drag the notification bar down (which doesn't do anything)
- Unlock the phone
- Then it works again!!
My mrs had this too, and my workaround fixed it.
This issue has spanned over multiple versions of Android and is now doing my head in.
Any ideas?
Some app overlay is on top of it such as: Flux, blue light filter, and things like that. Once disable the issue is gone. That might be your issue.

I would place a 90% bet on this being a carried over app problem. Have you tried a fresh reset and reproduced the problem?
Have you also tried the service test for Touch ans S Pen? *#0*#

I think so too. One example I have an issue with is the offscreen memo function. I pull the stylus out and can write on the screen off, but the row of buttons along the top NEVER work! But, I should say on a hard reset it was fine until all the apps were installed and logged into, or a setting was put in place. The service test for S Pen and Touch works perfectly. All I can think is trying to install 1 app at a time, and seeing what happens as a result. Will be painful with 100+ apps though. I'm about to replace my N7 on the recall too so I want to hold off on a hard reset too.
I feel your pain, if it were me I would rather discover the erroneous app now than later. Perhaps a backup via smartswitch on PC (very fast over USB 3) and when you know which app restore the backup and delete the app accordingly?

By pure luck. I found it. 3 years of pain and I nailed the bugger! Something you said triggered a thought process.
It was....
Cerberus security! An app that automatically hides itself from the draw once it's installed so usually never crossed my mind.
Disabling the "Block Status bar" feature in Cerberus fixed it.
PHEW!!!!!!!!!!! Thanks for this (both of you).
good for you!
