Ever checked development options under applications settings for never sleep while charging?? Also check your screen timeout option under display settings.

Issue with screen (scrambled white screen)

Hey guys,
I have a problem with the screen of my Galaxy S3, I locked the phone and 2 minutes later when I pressed the power button to get to the unlock screen, it turned white (see the picture I attached). The phone didn't fell or hit something, nor enter in contact with a liquid, I mean for no reason I got the scrambled white screen. I took out the battery and reboot but once the phone boots there's the white screen.
If anybody as encoutered the same issue and found a solution please let me know.
Thanks
Can you still enter download mode or recovery mode?

No I can't, once I press the power button I immediatly have the white screen.
take it back to where you purchased it, you have a faulty screen
Wel try to boot into download mode by holding the power+ home+volume down and if it doesn't work your phone is definitely bricked

It happened to me yesterday! i left the phone to charge overnight and it is having an 7200mAh battery from iAnker.
could it be because of the battery?
when i go into download mode the screen works.
Recovery doesnt work

Red screen

Hello guys,
Today while I was using Llama to config some actions my screen got red, yes... seems to be a red layer over all the screen.
It doesn't flash or blink and isn't that red border error.
I tried to reboot. While shuting down or turning on the screen is normal, the Samsung logo screens are normal. When the android stars the screen is red again.
I also tried to change screen configs on native screen config options, but had no sucess.
The attached file shows the error...
PS: what seems to be the red layer does not apply to notifications, wifi connection in the screenshot.
Does anyone have any suggestion about this?
Thanks!

Try something for me, if you could: adjust the brightness manually. Does it affect the color or how much it is colored? Does just removing Llama help or the settings are already stuck? Factory reset and / or reloading the OS is always an option, though not always the most desirable one.
Thanks for your reply.
When adjusting the brightness manually the red color follows the brightness changes.
I have removed Llama and restarted the phone, but nothing has changed.
Yes... i was thinking about factory reset, but will wait a little before that =)

Interesting info: when someone calls me the screen gets normal (no more red overlay) until the end of the call. After the call is finished everything is red again!!!
So weird lol...

Something is using this: http://www.jdepths.com/2013/01/how-to-overlay-view-over-everything-on.html
Maybe you can run a logcat and look for it there?
That's exaclty what happened!
Could you help me how to do that?
I don't know exactly how to run the log.

Or on PC if you have adb setup:
adb logcat
Then post your findings to pastebin.org for others to read it easiest.
I have uninstalled lux lite dash, which manages screen brightness,; and the problem was gone!
Thks for your help guys!

Ahhh You didn't mention having that one. Definitely would have been a...red flag.
