I have listed my problem before but got no satisfactory solution so opened this topic...
I am on cm9 alpha 9 before this was on RemICS.
I have noticed that after about two days use the screen becomes less sensitive..No lags..just seems like the screen does not register my touch.scrolling with my right hand by thumb supported by Palm makes it easy..but scrolling unsupported is not possible .eg-keeping on table and scrolling.
Here's the weird part - restarting solves the issue only to recur in about two days.
Also i have noticed installing beats audio causes the issue in under one day
Can anyone help?? Many thanks...
Weird !
I sometimes experienced different issues after two days on almost all cm9 based Rom.
Sometimes the phone becomes unresponsive suddenly. The screen goes black, though the background is lit. Touch buttons keep lit.
Lock button also doesn't solve the issue. Locking-backlight off, unlocking-backlight on.but no screen. Returns after two to three minutes on its own.

I got nexus s (i9020T) recently and found the touch screen unresponsive sometimes. I've already tried several launchers(adw, lancherpro, go launcher ex), and it seems not launcher's problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
Later I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally.
I'm confused by the strange behavior, anyone experienced similar issue?
more info from test,
I connect my phone with adb, and tried to "cat /dev/input/event0"
The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I don't know kernel very well, so I cannot find the source code Any help please?
FYI. we are not alone.

I got this problem too whenever my phone is in my pocket facing inward.
I have tried to open the calculator to see which part of the screen having problem. Mine is usually the "8" and "5" location unresponsive if my phone stayed in my pocket facing inwards for a certain period of time.
The problem will goes off after couple of mins when i can feel that the phone is cooler than my body temp.
I knew this happens to the Dell Streak as well.
Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks
Hey guys,
Had my transformer for 2weeks now and loving it. However recently (first noticed it 2 days ago) the notification bar has randomly started opening itself. It doesnt happen on a regular schedule -sometimes it will happen 3 or4 times in a couple of minutes, sometimes only once or twice an hour but not less often than that.
It happens even when im not touching the tablet at the time so i dont think the screen accuracy/calibration would be causing it.
I have turned it off and off a number of times to no avail and Ive also tried a factory reset and even with no additional apps installed it still happens.
Finally ive tried it both with and without sd card in and it happens in both situations.
Oh, and the dock connector being attached or unattached doesnt stop it either.
Has anyone heard of this happening before and or have any ideas to solve this problem?
i get this too all the time. i'm not touching the screen and the notification pops up for no reason. sometimes apps open up randomly too, for example i get an email notification and the email app opens. very annoying when plugged into a projector whilst giving a presentation.
somebody must be able to help. I'm not rooted by the way and have no intention too.
Sounds like a hardware problem - the touchscreen registering fake touch events. Check for mechanical stress in the lower right corner.
Update
I probably should have added, like yours mine isn't rooted.
I also turned on the developer options for touch detection, and it's definitely detecting "phantom" touches in the bottom right corner so definitely hardware not software issue.
Unfortunately, yesterday I started having issues with the touch screen being unresponsive in the right third or so of the screen, so I've called Asus this morning and am RMAing the tablet anyway.
I'd suggest you do the same rob if it's still in warranty, in case its a prelude to larger issues like mine was.
interesting thanks both. i was weighing up an rma because my keyboard dock is getting very loose, letting the top of tablet move about an inch without hinge moving. i've turned on show screen taps and already seen one. thanks again.
I've got Xperia J with CM 10, release FXP217, kernel version 3.0.8. Everything seems all right and the phone works as it should (except of the known issues and bugs). But I noticed that nobody mentioned, that their touch freezes or anything.
The main issue and reason for asking this question - sometimes my screen, or rather touch, freezes and there's nothing I can do with it. It doesn't react to any movement, but the phone itself remains functional and does everything normally, so it doesn't remain active or anything, just doesn't react to any touch at all. I have to press power button a lot before it starts reacting again. I usually press the power button and move my finger across the screen for as long as it doesn't lock itself or unfreeze.
At other occasions it does something a bit different - the touch gets a bit dull and unresponsive in general, but after some using it, it goes back to normal. When using the Pointer location overlay i noticed, that while I move my finger across the screen, the trail stops for a half a second or so and continues. It's like the touch periodically gets "disabled" or something. But when I press HARD and move my finger a bit slower than regularly it mostly is good and after some time - it gets back to normal.
One day it may occur twice or maybe even not at all, sometimes it happens a lot, like even 4-7 times; at rare occasions, this problem reoccures in small periods of time (like when I use the touch screen a lot).
Is there anything known about this issue? Is there a fix for that?
Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
