There is a text message on the mobile phone in the middle of the night for no reason.

Does this kind of short message only appear when it is sent by a specific person? Or you can clear it. When you receive a short message, drop down the mobile phone notification bar and click Clear to delete the notification. You can also try to restore the settings, and go to phone settings-General/More Settings-Restore factory settings-Restore all settings (without deleting any data of the phone).

If you have any questions, please feel free to consult us. Thank you very much for your support of our vivo. I wish you a happy life!
