How to Force the iPhone XR or XS to Reboot
Maybe your iPhone’s touchscreen isn’t registering your fingers, or an app just froze. Whatever the reason, there will come a time where you’ll want to know how to force your new iPhone to reboot.

1. Press and quickly release the Volume Up button.
2. Now press and quickly release the Volume Down button.
