Hey all, I couldn't get the ring notifications working with the app on S10, but I have found a solution. The app is called "Always on AMOLED" and there is a setting to have a blinking light when a notification comes. No added screen, only downside is its only one color. Anyway, thought id share! It would be neat if there was an app that could have multiple different colored flashing dots when the screen is off, so for example, you get a text and fb message, 2 different colored dots on the screen.
