My Samsung mobile phone suddenly connected automatically. What happened?

The following actions are recommended:

1. If conditions permit, replace the spare battery. Test whether it is caused by poor battery performance.

2. Take out the battery, and clean the battery metal contact and the mobile phone battery contact with rubber. Eliminate poor contact caused by oxide layer of battery metal contact.

3. Back up mobile phone data (phone book, SMS, multimedia materials, etc.). ), and tried to restore the factory settings of the mobile phone, which initially ruled out the system problems caused by installing third-party plug-ins.

If the problem still exists, it is recommended to bring three purchase vouchers and send the mobile phone to the nearest Samsung service center for testing.
