Fantastic! ...unless you have certain phones I loved this app on my Galaxy S4. I would like to love it on my LG G4  but I can't use it. The G4 (and some others) interpret a double-tap as a """"""""""""""""knockON"""""""""""""""" code which immediately locks and turns off the screen - it can't be changed or disabled. Well  not without using yet another third party to circumvent it. If Musei could allow other gestures (three taps  two finger tap  etc) to be used  it would be useful to folks like me again. That issue aside  there are some great addons available for Musei!""
