My iPhone turned itself off and back on?

An hour after I completely reset the phone, the phone screen went dark and then the Apple logo appeared again. So it seems that my phone just turned itself off and back on… But does anybody have any idea why? It hasn't happened since, though.

It is just restarting, that happens with computers and cellphones. Nothing to worry about, and may also be updating the software.

It was blinking

Sometimes your phone will reboot. It's normal.

  • My iphone has turned itself off and won't come back on? I have the iphone 4 8g and I have had it for only a month, it is well looked after and I locked the phone then 3 minutes later I tried to access it and it is off and will not come back on, I think I had received a phone call which could have frozen the phone, does anyone know what this is? The phone was purchased from an 02 store and is on pay as you go.
