My phone dropped while on, back over open and the battery popped out. basically turned off prematurely. At reboot strange messages from some apps (Swiftkey, whatsapp, go sms pro): apparently run out of memory (while 5GB still free on phone's memory. Aftre some minor attempts I have formatted the SD and perfomed a factory reset, hoewever once reinstalled the apps, the problem is still there. I have noticed that the factory reset will not wipe out the phone's memory as all the users folders are still there. Could it be the phone memory filesystem got corrupt? In this case how can I format the phone's memory? My phone is rooted and got CWM installed. Maybe I could format the phone meory from bootloader and flash stock ROM from bootloader?
