How to enable an "Always on Display" mode in Nokia 9 for JUST notifications? In Nokia 9 with Android 10, I set Settings=&gt;Display=&gt;Advance=&gt;Screen timeout to 30 seconds, but I still like be aware when I have notifications waiting to be reviewed.
In Settings=&gt;Display=&gt;Advanced there are Glance view options:

The default 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 &quot;fully&quot; 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.

Here is what I get when the screen is supposed to be turned off:
To enable notifications on lock screen:
adb shell settings secure put lock_screen_show_notifications 1
