Samsung Galaxy SII
After about 10 seconds after i lock the phone and try to unlock it, nothing happens. It stays black if i hold the Power button it restarts the phone. I have reformatted the SD Card and reset the phone. Still continues to do this. Every now and then it will reboot on its own after unlocking it.
