The notification light informs you about battery status and some other events. The notification light is enabled by default but can be disabled manually.
- When the notification light is disabled, it only lights up when there is a battery status warning, for example, when the battery level goes below 15 percent.
Find and tap [Settings] > [Apps & notifications] > [Configure notifications].
Tap the [Use LED light to show incoming notifications] switch to enable or disable the function.
