My iPhone 7 plus works but every, but every few minutes, it turns off and restarts

Hi ‘dan from the west nmsol’,

Your phone is NOT ok if it keeps shutting down on its own.

Do a hard reset/Forced Reset -

Press and hold both the VOLUME

DOWN button and the SLEEP/WAKE

button at the same time.

When the Apple logo appears, release both buttons. I hope this helps.
