Recently I dropped my phone after being bumped into by my niece, 2 weeks ago. Ever since then, my phone has been turning on/off by itself at random times. For example, I will be texting a friend and it will turn off, and start buzzing multiple times trying to turn itself back on, usually after a few minutes the Android screen and set-up will turn on and boot itself up, but sometimes the screen cuts out. I have done a factory reset, thinking that would help the problem and it was going good for a few hours until it turned off by itself again. I got my S2 in February and I do have warranty. Does anybody have any advice to help me with? Do I have to get a new phone? Thanks in advance to any help I should receive! Sam.
