Always show ring is already off, hence the question.
Except I'm also trialing aodnotify and it doesn't show a ring when I switch to it. So for the time being I'm sticking with that one.You probably have an app that is creating a notification light, you have to set up all app that you don't want to have a notification to be 100% transparent, or every app will have a notification, such as casting something or playing Spotify music
These things simply awesome. It works flawlessly since yesterday. The only thing is that if you mix the battery indicator with notification indicator it's not that easy to understand
