Hello,
this is my dad's phone and it started rebooting by itself. When phone boots you can use it for 30 seconds and then it reboots again. I tried to factory reset from settings but nothing happens when I press ok on the last menu. So i tried opening menu when phone is booting (power button + volume down) and selecting factory reset with power button. Phone then showes red triangle with exclamation mark. After 2 minutes phone reboots itself without doing factory reset.
