If your iPhone is not behaving as expected and simply turning it off and on again isn't solving the issue, then it's time for a complete restart!
Follow these simple steps for a hassle-free restart:
- Quickly tap the volume up button and release it swiftly
- Quickly press the volume down button and release it swiftly.
- Hold down the right side button until the Apple logo appears, then release the button.
- The phone will now restart completely (which may take longer compared to a regular shutdown).
