I've used Lightflow for several years now and use it a lot. No problems... until now! I tried the paid version of Light Flow (I am a heavy notification user) and it doesn't work. Tried many settings and workarounds (including the Samsung-specific workaround, direct mode, etc.). Nothing. And the worst problem is that the always-on screen of the S7/Edge only shows missed calls and SMS messages... and the blue LED light when I want the red or purple LED light. I am quite stuck at this point. I don't want the miss/blocked call notification either, but it looks like I'm stuck with that.
