So I updated to 4.4 kitkat, after the update the phone was operating normally. Then after a few days the device seemed to be missing the camera. The apk file and gallery apk are still on the phone, its just you cant access the camera through the app tray because it doesnt show up. When I installed a third party camera app the camera would only activate the front facing and not the back camera. After you install third party camera apps if you reboot the device it deletes the app from the app tray. Ive tried flashing random camera and gallery apks and ive tried flashing to stock, ive tried putting a apk in system/apps file and then fixing the permissions. I have no idea how to fix this at this point, Is their any way to completely factory rest this and undo what google has done to it.
