Typically, an Ambient display solution which turns on the screen only when notifications are present, remains on, but turns off when they are dismissed.
This feature is meant to show you which notifications you got piled up at any given time. Once you handle them, the phone's screen goes off again.
Unfortunately some phones don't seem to have such a native option (cough Nokia 9 PureView cough), so is there an app that can do it for them?
