Hi, I am new here and would appreciate your help. I have a Samsung Galaxy SII that constantly is restarting itself when unplugged from power or a USB connection to my computer. I called sprint and they said I needed to do a hard re-set. I wanted to back up the phone first so I said I would call back...but if someone here can help me with this I would appreciate it...or if another solution is out there I am open. I would rather NOT lose everything on my phone and have to reset it.
