I just replaced it with an UMIDIGI A9 PRO 2021 (Android 10) and to my dismay, the discreet LED is gone.
I checked a few options using flash or edges on Google Play but either they are device-specific, too agressive, not persistent or have ads like no tomorrow.
The idea is that I am notified even if the screen is off and it needs to be continous [persistent] and discreet. Flash is too aggressive to my taste.
Before I get in another round of trials, any recommandation or suggestion? TIA
