OK, so I formated my SD card, did fresh install, installed apps one by one and so far everything is great. One thing I did is disabled automatic software update, so my "Android market" didn't upgrade to "Google Play"! So my guess is that Google play was the problem.
Anyone have the same problem?
Is there a way to downgrade "Google Play" back to "Android Market" if I try to upgrade?
Does new "Goole Play" have any advantages over "Android Market", like some apps doesn't show up?
