S8 WeChat sent a message. What's wrong with the led light?

If the LED indicator of the mobile phone is not lit or there is an unread notice when the mobile phone is charging, it is suggested that:

1. Check whether the LED indicator is on (Settings-Display -LED indicator).

2. Check whether the notification of the software is turned on (e.g. WeChat: Settings-Notification-Slide on-WeChat-Slide on).

3. If it is still not displayed, please update the software version or try to reinstall after uninstalling.

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

5. If the LED indicator is still not lit after the above operation, please bring the purchase invoice, maintenance card and machine to Samsung Service Center for inspection.
