If your phone isn't turning on I recommend to reboot it If you dont know how to then I'll show you. I want you to hold the power button and volume button (+ or - either way it still works) And wait for a 10 seconds or less. Then you'll feel the vibration which means it's rebooting If you get the FTM sign then do the same with the hold power and volume. That's all enjoy having your dead phone alive again
