I just got this ipad2 64gb At&T 1 week ago, it was working good until today. It just randomly goes to wherever it could, plays music by itself, or goes to notes and type random letters in it. It even goes to settings and messes everything up from languages to passcode. Is that some kind of bug or some system error ? by the way, i've never dropped it or hit it before. The only thing i can think of is when my dad put ghost armor on it (i saw him spraying a lot of liquid) then he blew dry it with hair dryer (cold air). But he did this to his iphone long time ago and it's working totally fine.
