The app is mainly developed for remote control of Android TV sticks but as well works with a wide range of smart phones and tablets. The app is separated in two parts: 1. Pressing the 'Allow Remote Control' button allows screen sharing and remote control of the current device.
That mode requires ROOT PERMISSIONS 2. Pressing the 'Connect' button allows you to see the screen of a streaming device and as well remote control it. That mode does NOT require root permissions For streaming your screen and/or been remote controlled you need ROOT permission!!!
