My phone went crazy this morning. it started vibrating like i was getting a phone call i looked at it the screen wasnt lighting up but it was a constant vibration. it wouldnt stop. after a bout 40 seconds i pulled the battery. now my sd card says unsupported format. ive tried formating it on the phone and it wont do it. so i took it out and tried reformating it on my computer. still doesnt work. i cant get anything to reformat it. anyone else had this happen?
