1. First, judge whether there is a problem with the system. You can press the switch button of your mobile phone to restart it and see if there is any response. If you can restart the phone, it may just be caused by system disorder.

2. If pressing the on/off key of the mobile phone doesn't respond or it can't be turned off, it may be caused by the crash of the mobile phone system. You can hold down the power button and the home button with your hand at the same time, and after a few seconds, the Apple phone will shut down and restart.

3. You can also solve the white screen problem by brushing iTunes. Before brushing your teeth, keep 40% of the remaining power in your phone, and connect your Apple phone to iTunes.

4. Then press the power button to turn off the Apple mobile phone, press and hold the power button for 3 seconds, then press and hold the home button for about 10 second at the same time, release the power button and keep the volume button unchanged.

5. When the iTunes interface prompts the user that an iphone is in recovery mode, please release the button, press shift, select the downloaded firmware to recover, and the mobile phone system can be refreshed again.
