Why can't I receive messages and videos after my phone is locked?

During the lock screen of the mobile phone, it is likely that all background software will stop running.

How to recover if the Android phone lock screen can't receive anything;

1. Turn off the phone completely first, then press the volume down button by hand, and then press the power button until the screen lights up.

On the screen, there is an Android robot and a warning exclamation point. At the same time, press the volume increase or decrease key to display the operation interface. Restore the interface, the volume increase or decrease key controls the up and down, and the power key is OK.

3. In the recovery interface, press the volume down button to select Erase Data/Restore Factory Settings, then press the power button to confirm, and then select Yes-delete all user data and press the power button to confirm.

4. In the recovery interface, press the volume down button to select the erase cache partition, then press the power button to confirm, then select Yes-erase cache, and press the power button to confirm.

5. When finished, return to the recovery of the main interface, and then select Restart System to restart the phone now.
