I'm developing an standalone alarm app who setup a timer and trigger a notification using AlarmManager. Currently it's already working by triggering simple notifications, but I'm changing it to show full screen notifications as an alert screen with custom vibration when the timer reach the end.

The point is when I change the notification to full screen, nothing happens. I just discovered yesterday that for Galaxy Watch devices I need to enable "Turn on Screen" when receive notifications in my Wearable device app, so only that way the notification works as expected.

Although this is working great, it's really annoying to have all the notifications for every app to turn on my watch, and also I would need to advise my app users to change this option in their apps manually, who is also not cool.

I would like to know if anyone already had to deal with similar issue, of if you know there is some special permission available to by-pass this restriction for alarm apps. I also gave a chance to Wake Lock but since it not working as well I suspect that it can be a Samsung restriction too.

I'm testing with a Galaxy Watch6.

Thank you.
