The LED light of SMS reminder is not on.

According to your description, if the mobile phone LED indicator is abnormal, I suggest you:

1. operation: set-display -LED indicator-charge/low battery/notification/voice recording, and select the box as required.

2. If the LED indicator lights up automatically all the time, it is recommended that the standby interface slide down the top curtain of the screen to check whether there are missed notices or missed calls in the notification bar.

3. If the LED indicator is still not normal, it is recommended to try to back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings (Settings-Reset/Privacy/Personal-Restore Factory Settings).

4. Check whether the phone has the latest firmware version, and if so, try to update the firmware. Operation: Settings-(General)-About Equipment-System Update.

If not, please bring the purchase invoice, maintenance card and machine to the Samsung service center for professional after-sales engineers to help with the inspection.
