Just did it to me again, and this time the fix was.... Unplugging the headphone cable... Hmmm

Yeah it does it to me periodically throughout the day. Hopefully just a software glitch.

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?

[Q] quick toggles disappeared

Got my shiny s4 the other day, all working well.
Now I did get an ota yesterday, don't know if this has anything to do with my issue.
The first day I could pull down the notifications area with two fingers to get all the quick settings.
Then there was all twenty or so toggles.
Now it's just the 7 basic ones.
And I can't add more from the settings, unless there is some hidden menus...
Any help appreciated!

I also have this issue. I had loads of toggles when first got phone then all of a sudden I only have 7. No toggle for air view, ect
Okay, good to know I'm not they only one...
But what to do?
Going for root and a custom Rom as soon as there is somethin stable out there.

Wild guess, have you turned on Talkback under Accessibility?
Nope, no talkback...
Sent from my GT-I9505 using xda premium
Mine all disappeared once, and I had no toggles at all.
A factory reset brought them back up again.
Did you root and backup?

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

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

Screen wake during call

Something weird is happening during a phone call. While I'm talking I'll pull the phone away from my head and the screen won't turn on, ever. Even when I want to end the call I have to press the power button and then end call after the screen turns on. Doesn't matter what ROM I'm on. Also a buddy who isn't even rooted has the same problem. I'm hoping it just a stupid setting.
Any ideas?

Same problem here.. even on a fresh room install.. so I'm afraid it is not a settings issue

Do you guys have a case for it? Maybe the sensor is covered somehow.
Sent from my SM-N900V using Tapatalk
Yes I have a case but I had the case since I got the phone and it only recently started doing this
Sent from my SM-N900V using Tapatalk
Took the case off and tried nothing. Does it go by a light sensor or the gyro?
Sent from my SM-N900V using Tapatalk
No case here either. Very strange

Mine started do this as well. After phone call pull the phone away and have to hit power button to turn screen on.

Happened to me and I found the solution on another thread. Sounds stupid but it worked for me. Blow into the ear piece. I used a compressed air spray can but it may work with just your mouth. Apparently some dust gets in front of the proximity detector inside the phone next to the ear piece. This removed it. Give it a shot.
