I have Samsung Galaxy S7 Edge on Android 8.0 Oreo (additional software information). Until yesterday, application notifications were flashing on the LED indicator, but from yesterday to today it stopped happening, even though nothing updated on the device.
It warns that it is charging with the red LED, and it warns when it has finished charging with the blue LED, but it does not flash to notify that there are new notifications as it used to do.
I checked if LED it's enabled, and yes it is.
I already checked if the applications are activated, yes they are.
I checked if it's in DO NOT DISTURB mode, and it's not.
I haven't changed any settings from yesterday to today, however, this is happening.
What can I check to try to find the problem?
