Ultra.Numan , via OnePlus 6 , Oct 21, 2020 : After the most recent OnePlus 6 update (10.3.6) the notification LED has stopped working and the icons seamed to be hit and miss. Checked the settings and all relevant apps are on the list for LED ON. Anyone else had this issue? And any fixes?
drl431 , Oct 21, 2020 : I have noticed that since upgrading to Android 10, last year, the OP6 notification LED sometimes does not work. But is does work 80 or 90% of the time. You can submit a bug report via the feedback forum.
