I installed PixelOS 13.0 on my Mi 9 a couple days ago and it's been mostly great, but one thing I've noticed is the blinking notification light will stay on at times even when I've cleared all my notifications, and I've checked my notification log in case there's a suppressed one that I missed so I'm pretty sure that's not the cause either.
Is that a known bug or just my build?
The basic sequence is that a notification comes in, is dealt with and then the led stays blinking. Restarts have no effect. The only thing I've seen make a difference is charging the phone to near capacity (the blinking led is solidly on to signify the phone is charging so I can only surmise it overrides whatever is causing the blinking). I have had battery saver mode on, but I still see the blinking light now with battery saver off so Im not sure that's related in any way.
Any guidance appreciated.
Edit: After more rooting about, this definitely is tied to Battery Saver. I factory reset the ROM, then caused the issue to occur by setting Batter Saver on a schedule (auto on at 75%, but it shouldn't matter what you set it at). This caused an Extreme Batter Saver discovery notification to appear. I dealt with that and the blinking LED never went away. If you go to Battery>Turn on the light when charging and set it to off the blinking light goes off. So I guess the phone somehow thinks it's in some state that resembles charging. Can't see an obvious fix without addressing it in the build.
