Press and hold the Power button (located on the right side, integrated into the fingerprint sensor) until the power menu appears on the screen.

On the screen, you will see options like Power off , Restart , and Screenshot . Press and hold the Power off option. Do not tap it once—hold your finger down on the text or icon.

Press and hold the Power button for 10–15 seconds until the phone vibrates and the screen goes black (forced reboot).
