[BUG] Screen Sensitivity Issue-Lag (4.0.4-4.1.x)

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:

Your hands are really dirty or really dry. Try moisturizer or something.

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.

[Q] Default Messenger App Randomly Opens

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.

Tried that, just a moment ago. Moved my messenger app over along the bottom and put a browser in the spot the messenger app was. However, now my phone is randomly launching the Car app.

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.

Did that, the line appeared on the screen as I drew.
I feel I should mention that the car app is now randomly launching even when I press the home button.

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.

Touch screen problem

Weird this. I sometimes find that the 'dock' area of the screen will not respond to new touches. Therefore I can't open the phone or the app drawer etc. Odd thing is that I can drag icons from elsewhere over the area which makes me think this is more a software issue than a hardware one. If I open Chrome links can't be opened if they are in the affected area. It's just weird.
Some times this requires a reboot to clear but other times it appears to clear by itself. From my observations it seems to start after using the camera app.
Any ideas? Could this still be down to a defective device?
Matt.

I experienced the exact same thing. Everything else works normal though. It happens after using the Camera app and goes away after I clear the app from the multitasking window (which I have to do app by app since also "Clear all" can't be tapped). I just hope its a software bug that can be fixed by an update.

Clearing running apps doesn't sort the problem on mine. Your problem certainly sounds very similar though especially given the connection with the camera app in your case as well. Tried a factory reset and the problem persists but it is very random and difficult to reproduce. Still not 100% sure it's not some sort of hardware fault as I can't really see any touch screen related problems being reported on the web and this one is very irritating.

I experienced this once - also after having the camera. I rebooted and haven't experienced it again.

I have the same problem where my touch screen doesnt respond in the corners sometimes. Really abnoxious when playing games and then i just lose because of this. I send my phone to HTC and i waited 20 days to get my phone back with the same problem as before. First i downloaded a touch screen test app, and there it didnt show any response in the corners but another touch screen test app registered every touch.

I have the same problem. Seems to be caused by either the camera or the photos app. Closing them doesn't help here, but a reboot does. It's something that started happening recently so I hope an update of some sort will fix this.
Very annoying... If anyone has found a permanent solution I hope they'll share it here.

Yes it is a software issue. U just need to revert the photos app back to the factory version. This can be done by going into settings >apps >photos app and the click on uninstall updates. Then reboot your device and the problem should be gone. Try it out and tell us if it works for u as well.

Strange edge lighting behaviour

So I have a really strange thing going on with edge lighting which is driving me crazy.
Whenever I play Elder Scrolls Blades the edge lighting appears but only in the bottom of the screen. As far as I been able to tell this only happens in this app though I can't be 100% sure.
Now what is strange other than it happens only in the bottom of the screen is that it keeps happening every few seconds, there is no notifications received and it happens, if I disable edge lighting it still happens, no matter to what effect I set the lighting it always happens in stock blue.
I can't possibly figure out what is this and I tried everything, any ideas would be appreciated.

Same thing here, in at least 2 games...
Thought it was related to spen, but it seems not...
Tried to disable Game Launcher but still got these random bottom screen notification pulse... And stock blue aswell. Got no clue atm

Thanks for letting me know I'm not the only one experiencing this. I tried literally everything and nothing seems to fix it. What's also weird is that the lighting comes in irregular intervals, sometimes just going crazy and sometimes appearing much less.

I have just discovered this issue appears in all games so it's a bigger problem then I originally thought. If disabling the game launcher does nothing then it makes it even more strange and annoying.

Yeah, same here, happens on basically all the games.
Maybe related to game booster?
Let's try to compare our setup : are you using any notification enhancement app? (like aodNotify)
Are you using your spen while playing?
But yeah, this random glow line **** is driving me crazy too!

Currently I am using aodNotify though I tried uninstalling it and the problem persists, I also have goodlock installed and the edgeslighting+, same thing with and without it. I am not using the spen, but I have tried just taking it out while the game is running and leaving it out for 5 mins, no change. I have disabled and enabled the stock edge lighting as well and the problem is still there. Nothing seems to effect it. Its ridiculous

i tried on mobile legend adventure, no problem on it, perhaps a scaling issue?

Will try to tweak full screen mode.
Increasing dpi doesn't change the weird thing, neither switching from Samsung stock launcher to Nova...
Also I'm using gestures based navbar, but I also tried with or without tips display, standard navbar... Still occurring.
Did you go from a scratch Note 10+ or used SideSync to switch? (I was coming from a Note 8)

I don't think it has anything to do with scaling, I tried setting the game on full screen and automatic, both giving the same results.
I used Smartswitch from Note 9.
Later today the camera effect from aodnotify started appearing in the game aswell (landscape mode), along with the edge lighting.?
I uninstalled aodnotify afterwards, found out there is a aodnotify Manager plugin which stays after uninstalling the main app.
Uninstalled the plugin aswell, opened edgescreen from the system app and cleared cache.
It was showing the app was using RAM with high frequency.
I don't have the time to check now does this fix the problem but will let you know once I do.
The only other thing left to do if this doesn't work is to clear edge screen data.

Will try this aswell, and restore all the notifications and edge lightning settings...

What I wrote above didn't work so I disabled the option for edge screen to show on top of other apps, so far this seems to fix the problem.

Unfortunately I was wrong and nothing above fixes the problem. I also wiped the entire edge screen memory, no effect. This is the weirdest thing I ever encountered in my years of Samsung phones and it's extremely annoying that there is no fix.

Strange, I don't have any issue.
Did you try with and without locking the screen orientation to see if edge lightning follows settings as it should?
I personally only use auto orientation.

I also use auto rotation and it happens the same way in landscape and portrait, the most annoying thing is that it happens really much, like 2-3 times in 10 seconds, or sometimes doesn't happen for few minutes then starts going like crazy, and as I said before there is no notifications or anything.

Same here, auto rotate on, only occurring during games.
I don't even know if I can debug which process is running these random edge notifications, without dig into tons of log files...
And if not, I guess I'll try to factory reset and re-sync again..

Its incredible that a factory reset seems like only possible solution left but I hope maybe some future update will fix it since I hate doing factory reset. Please keep me posted if you discover anything new.

Hating doing it aswell but this is too damn annoying..
If no clue, I'll go for a restore without restoring system settings... Maybe some notifications behaviors have been messed up
I'll keep you in touch for sure

Tried to wipe cache partition, still no clues...
Did this also got triggered in portrait mode game?
So confusing...

Yes it happens in all games no matter of the screen orientation. I really have no more ideas aswell

Got some news, another post is talking about this : https://forum.xda-developers.com/galaxy-note-10+/help/strange-blue-bar-games-t3963939
Seems related to the new game booster feature "temp and cpu monitoring"
Will try to disable this for a specific game and see...

Question Freezing for a Few Seconds Since Last Update?

Anyone else have their Fold 3 keep on freezing for a few seconds at times, ever since the last update? It has done it when using Facebook Messenger via Chat Heads, opening the list of open apps (via the three lines button ||| ) to switch/close an app, Facebook app, Samsung Browser, tapping the back button, and possibly other times. Really annoying!

My screen will go blank when I close a app sometimes. The screen is powered on but all my app icons won't be there. Just the background.

I've had this issue since I got the device. It happens whenever I unfold the device from using the outer screen and it's not an immediate switch, it takes a couple seconds like it hangs. And I've tried 6 different launchers and tons of different apps and nothing changes it. I've debloated my device as much as I can without losing the functionality I need and followed the oneui optimization guide with a bunch of adb commands to make it better and I've had no luck BUT my battery life is amazing and the overall performance is good so I'm at a loss.

Oh, that's an odd one! I haven't had that one happen. It was getting frozen right after the opened app view came up, so I couldn't swipe an app closed or switch to another one right away.
Thankfully, the phone seems to be working better now after I reset the phone earlier, so here's hoping it stays that way.

I don't use the front screen much, so only have done that switch a few times over the year plus I've had the phone. I think it does take a second or two to switch, but not too bad since you're getting it set in your hands anyway, IME.

Okay, well it still does the freezing thing, but not as bad as it did before the reboot. I'd report it to Samsung, but their customer service can't understand English so can't understand problems correctly. I have an issue with scrolling screenshots not saving and they told me to reset my app settings, including network settings, and I separately gave a suggestion for the Bubbles feature to be able to open Bubbles (for texting) instead of waiting for that person to text me, and they told me to reset my network settings.
