Hi guys, I have a problem with my A500's screen. Everything wich is normally displayed as white or light gray is now displayed as a pink shade. here and there some green dots and stuff. at first it sometimes occured, and was fixed by a tap on the back of the A500 but now it is permanent..... on a side note: the A500 is not even damaged, no scratches nothing. So Im definatly sure that Its not caused by me banging the device around. Someone has experience with this? and can someone tell me if this is something that can get fixed under warranty?
