I bought a wireless keyboard and mouse for my Mi Box S. Everything works fine but the mouse. When I want to right click with the mouse it does what the back button on the regular remote. I want to play some but I can't like this. So I've found an app called Button Mapper. With it's pro version I can remap the back button to a custom key (right click in my case). And configure the app to only remap it when I play games. So my question is, is there any better solutions for my problem?
Maybe you can try this app when you have a android Phone. I work with this app on my mi box s and philips android tv.
