I just switched to Mi box s today from some cheap Android box. On my old box, I can use left mouse click to type, right mouse click to back (my mouse only have 3 buttons). But on Mi box, right mouse click can only chose something on the screen and can't use it to chose letter from on screen keyboard, the left mouse but seems to be doing nothing. Can anyone tell me how to solve this problem? (Sorry for the bad English)
Why?
