What happened when Samsung mobile phone was turned off and turned on when it was evaluated with Master Lu's mobile phone?

According to your description, the occurrence of smartphone failure will be affected by many factors. For example, third-party software conflicts, viruses, and excessive cache usage will all cause automatic restart. It is recommended that you try the following methods:

1, try to replace the battery, or send it to the service center for testing.

2. Uninstall the recently installed third-party software to preliminarily eliminate the causes of system software conflicts.

3. After taking out the external SD card, test whether there is a restart phenomenon.

4. Back up mobile phone data (phone book, text messages, pictures, etc. ) and restore the phone factory settings (enter phone settings-reset-restore factory settings).

If there are still problems through the above methods, it is recommended that you send your mobile phone to the nearest Samsung service center for testing.
