When I received an incoming email from Gmail app, my S20 just vibrate. The screen didn't light up at all. Not even the Always On Display.
So, where can I find a setting to wake up lock screen when notifications come in? Mine is S20 (T-mobile) running on One UI 2.5.
I'm talking about settings for all apps, not just for native Samsung apps. I allowed notifications for all apps, turned on Always on Display, Edge lighting (and turned off for experiment), turned off battery optimization. None of these settings seem to work for me.
Any suggestions other than installing third-party app?
