Works great on Galaxy S6 For those reporting errors using an S6 the app. needs to be manually started on boot/reboot. Once started it works as advertised. If you experience any trouble please go to Settings  Application  Running and check that the app is indeed running. Many battery saving apps will close it. Make sure it is Ignored. I am running Android 5.0.2 rooted. An excellent time saver.
