I've been using my razr for about a month now. Recently i notice that sometimes my screen doesnt respond when i try to navigate the i)browser ii)home screen or that sometimes it acts as if im trying to either rezise the page or trying to navigate away from the page when I'm not doing anything to it (causing it to move/blur erratically). A quickfix i found was to lock the phone, wait a few moment and unlock again. Apart from that i'm really happy and satisfied with the phone just that it gets really irritating when i'm in the middle of a game when that happens. Is it a known problem and is there any known fixes to this?

Pls advise and thanks in advance!
