view story

http://androidforums.com – Hay all, Just recently started using camera on samsung note and i get nothing but black screens like in some videos on youtube regarding samsung gs3 I also get bubble message over camera display: "warning camera failed" but if i restart phone and activate camera again i can still access all settings but then app crashes saying kill off or wait for app come back. I deleted all my music, games, movies, some say it needs update. Strange thing is when i do reboot phone and start up the flashlight stops for few seconds when i activate app button then on second time flash comes up. (General)
