What is the situation that Samsung E7 keeps turning off and on?

If your phone restarts automatically, we recommend that you:

1. Some machine batteries are detachable. It is recommended to take out the batteries and clean the battery contacts with cotton swabs. Then plug the battery back into the phone.

2. Uninstall and delete the recently installed software, and rule out whether it is caused by software incompatibility.

3. Try to replace other original batteries.

4. If there is an external SD card in the mobile phone, it is recommended to take it out temporarily to see if the same situation will happen.

5. Back up data (contacts, text messages, pictures, etc.). ) and try again after restoring the factory settings.

6. Check whether the mobile phone has a firmware/system update prompt. If so, please upgrade your mobile phone to the latest version.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test.
