The screen status of my mobile phone, why doesn't the light flash when there is information?

After setting the flashing notification function, the flash will not flash when there is a new notification or incoming call. Please operate:

1. Check whether other software is using flash, such as flashlight and camera.

2. Restart the phone and reset the flashing notification: Settings-(My Device)-Accessibility-Listening-Blinking Notification-Check.

3. Try to uninstall the recently installed third-party software.

4. If it is invalid, please back up data (such as contacts, multimedia files, etc.). ) and restore the phone to the factory settings.

If the problem still exists, it is recommended that you take the purchase invoice and three-guarantee certificate to the nearest after-sales service center for testing.
