I updated my girlfriend's GS4 m919 to stock 4.4.2 via odin about a month and a half ago with everything working fine until about last week when she complained that there was random restarts, lag when waking the screen, error where the camera would not work (shows black when camera is opened from any source ex. SnapChat, Instagram, Facebook, or the actual camera app), and also random FC when using apps. She doesn't update or tweak anything and I haven't seen this before and I've already tried to flash stock 4.4.2 via odin again but it started happening again after a day or so after. Any thoughts? ;(
