I'm running a rooted S3 on VZW with LiquidSmooth JB v2.7 recently flashed. Upon restarting the first time, I've got a silly blue circle that hangs out on the edge of the screen. Touching it moves it completely onto the screen, where a long press and drag does something but I can't easily explain what. What is this thing? It's transparent and visible over the home screen *and* application screens. I want to remove it, but don't see what it's tied to. Any suggestions?
