In Nokia 9 with Android 10, I set
Settings=>Display=>Advance=>Screen timeout to 30 seconds, but I still like be aware when I have notifications waiting to be reviewed.
Settings=>Display=>Advanced there are
Glance view options:
Glance display duration is
30 seconds. But I like to see all of the notifications which I missed when I wasn't around my phone, so I've changed it to
Always on...which got the screen to be constantly on!
True, it's not "fully" on. It's a black screen with a clock and battery percentage. But is there any way to keep the screen completely off and only keep the glance screen on if I actually have notifications waiting to be reviewed?
In other words, see how Wikipedia describes what I want:
Typically, an Ambient display solution which turns on the screen only when notifications are present, remains on, but turns off when they are dismissed.
