IPhonexr has updated 12.2. Why does touching the screen ring and vibrate?

The touch screen of the mobile phone is insensitive/out of order. Suggestions:

1. Check whether there is film on the mobile phone. If there is any suggestion, cancel the film on the screen and try again.

2. If the touch screen of the mobile phone is completely out of order, it is recommended that you restart the machine and observe it again.

3. try to update the version of the mobile phone system (note: please back up the data in the device before upgrading).

4. if it is invalid, back up the data in the device (contacts, SMS, photos, etc.) and try to restore the factory settings.
