Twitching screen

I've noticed an annoying bug on my touch screen on my sgs2, and wondered if anyone else has this problem.
Basically, the problem seems to be able to be reproduced by, for example, scrolling the settings menu with your finger, then stopping, but leaving your finger pressed on the screen, as if you were holding it still with your finger. Mine seems to be twitching and moving around slightly, it doesn't stay still.
Not a big deal you may think... But if your an angry birds player or a player of any game or app that requires precision movements then this is an annoying bug.
I'm on ke1. Can anyone else try this for me? Cheers.

Mine had stopped doing it now... But, I have noticed it before, so it seems I have an intermittent problem / fault / bug. Anyway, can everyone post here if they notice this... It happens in every app I've used that involves scrolling.

Nope, mine doesn't do this. And I'm glad about it! Sucks man, trey flashing a different rom.

Are you using a non samsung charger?
This used to be a charger problem, should work flawlessly with the charger thats provided with the phone

Could be a glitch in the motion setting, if you go to settings>motion and test the one where you put you finger on the screen and tilt the phone and the background moves.

Depends on quality of electric supply out of socket as well as which charger in my experience.

Mine was on charge when it happened, and it still happened some time after, but it stopped soon after.
3rd party charger (I leave my sammy one at home, I'm just using a spare for work)....
Could be that then?

If you were having screen flickering issues are they gone on 4.2.2?

I'm on 4.2.2 now and I can no longer reproduce screen flicker by scrolling fast in Music, nor by using WiFi analyzer. Since it was always an intermittent problem I was wondering if 4.2.2 fixed it for anyone else.

Is the flickering you're referring to the same as when the tab starts up?

I don't think so. The flickering I am talking about happens randomly during use, but I can reproduce it by opening the signal strength view of wifi analyzer, or by scrolling really really fast through a playlist in Google play music. I have not been able to reproduce the screen flickering in either since updating earlier today.

Haven't noticed this on my I9505, try using another keyboard
Sent from my GT-I9505 using xda premium

I'm having this issue and it's doing my head in!
Every time I bring up the on screen keyboard the hue changes slightly to greeny tone. Then back again when keyboard goes.
I'm surprised not more people mention it.
The easiest way I found to see it was ten brightness right down, go to a dark room and open play store. Touch on the search bar to bring up recent searches and keyboard, then hit the back button, then touch touch bar again, then the back button. Keep doing this so your toggling keyboard on and off and watch the whole screen shift tone.
I'd love to know if it's an issue across the board or if only a few phones are affected.

I am facing the exact issue bro but i hope it will be a software related issue but i am also worried that may be we have defective handsets because very few people raised voice against this issue so it means that most users are not suffering from this issue.

Is this for the stock keyboard? I'm using SwiftKey though.
Sent from my GT-I9505 using xda premium

I tried with other keyboard and its still there
Sent from my GT-I9500 using xda app-developers app

It's got nothing to do with the keyboard.
If you watch a movie on you tube (black and white is best) put to full screen and wait for slider to dissappear, then tap screen to bring it back. The hue changes to green!
It's whenever the screen has to bring something up like a keyboard, menu, slider etc.
Come on guys please can you test this so we know it's a problem on all handsets like smearing or if it's a hardware fault in a few handsets.

What auto tinting option ?? Where is it ??
Sent from my GT-I9500 using xda app-developers app

Lol there is no 'auto tinting' option. If you mean adjust screen tone, it makes no difference.
Sent from my GT-I9505 using XDA Premium HD app

This happens on kernels based on MDN below,
anything above MDM the tint issue is fixed.

On ME2 firmware and I experience the same issue. It feels kinda like a 'flicker'.

I have same keyboard tint problem too and its bugging me. Is it a sw or hw issue? Can it be fixed?

mostly all people have this problem & I was worried too about this. But update your phone. you should get a new update notification by now.! I already updated and it fixes this problem. and the smearing issue as well. And then you can also move your apps to sd!!!!!:victory:

Hi, just got my replacement after having some overheating problems and noticed this problem on the new one. I'm pretty sure is the screen, and not a software problem. Mine looks yellowish/greenish on the bottom. I downloaded Screen Test app and notice the problem. I have some pics showing the color differences along the screen. I'll go for another replacement tomorrow.

Renowned xda member bala gamer said that after installing MEA update this green tint issue is gone

Touchscreen issue

Hi Guys
I seem to be suffering from a issue where the touchscreen has a dead spot.
Now I had an earlier issue that caused all sorts of issues with screen responses - ultimately ending in no response unless I hit the power button to lock and then unlock.
That problem lasted about a week and then stopped - my thinking is that there was an app update that solved it.
Now however the issue has resurfaced (seemingly after other app updates) but it is a dead spot roughly where the first notification would be on the notification draw. Any ideas as how best to find out the cause of the issue, or a fix?
I've included screen shots showing the touch trace.
Cheers for any help

I can't help you but with some custom rom there can be a bug with it until I make some setting changes to the Nav Bar, but otherwise I don't know.

Forgot to say that this is stock 4.3

Many people are complaining about 4.3... It's causing many problems
Thu'umed from my Predator

What I don't get is why it went away after the first time.
I don't really want to factory reset if I can help it.
Is there a way to look at an update history for all your apps? Then I can pinpoint the offender.
Sent from my Nexus 4 using xda app-developers app

I've found a solution.
After factory reset and safe mode not helping I came across a comment in another thread.
You have to Disable HW Overlays and Force GPU Rendering. Now its not perfect and can have an occasional fit but does seem to solve the issue

Freaking out

So my nexus has always had a problem with the touch screen. But today it started freaking out self registering touches all over the screen. Switching screens. Opening task manager. Going home. All but opening apps. I tried searching got a lot of threads about grounding issues etc. But no one asking if this is hardware or a cyanogenmod 10.2 issue?

It's most certainly hardware fault. Send it for repair if you still have warranty.
