Sometimes, a third-party app may cause your device to lag, malfunction, or freeze. In Safe mode, all third-party app activities are temporarily deactivated. If your device functions as it should while in Safe mode, then the problem is caused by a third-party app and is unlikely a hardware issue.

Power off option.
Your device will restart and you should see
Safe mode at the bottom of the screen.

Use your device as usual and see if the problem persists or not while you're in Safe mode.
