Sorry for double post but...
SHIT,
I WAS WRONG AGAIN.
I put it on full bright, a few seconds after the screen fkd up again.
Here's my final conclusion...
When charger is put in, the brightness goes higher right? Well in my plan that I'm currently using, even if it's charged it still says a bit dark. If the screen goes bright the screen fucks up and I hhave to close it and reopen it.
