After the phone locks the screen, it lights up automatically every once in a while. What is the reason?

The mobile phone does not automatically light up the screen. It is recommended to refer to the following methods:

Setting reason:

1. For example, for short messages, turn on the setting switch of the short message pop-up window, and the screen will light up automatically when you receive the message. It is recommended to close the observation;

2.QQ software (for example, version V5.4. 1) has turned on the lock screen display message pop-up switch for message notification. When the message is received, the screen will light up automatically. It is recommended to turn off the switch.

Software reason:

1. Third-party software comes with advertisements or plug-ins, and the messages that are pushed will automatically light up. It is recommended to uninstall the software.

2. If you are not sure whether other third-party software causes the automatic screen display, it is recommended to back up the mobile phone data (phone book, SMS, photos, etc.). ) and restore the factory settings (Settings-System "More"-Restore the factory settings, please do not check "Completely Clear") or brush the machine for processing;

None of the above methods can solve it. Please back up your mobile phone data, and take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing.
