Hey. Im using Xiaomi's MiBox S(Android TV 8.1). Love that device, but recently I moved to a new flat, and need to have my TV mounted upside down. And that became a huge problem, because there is no option to flip the screen in both android nor TV settings.\
I have tried about 5 "rotation control" apps, and some of them let me change to portrait, reverse portrait even, but the one i want(reverse landscape) never works.
Can anyone help me find a solution to this problem?
PS. Ill try editing the build.prop, but that needs to wait till i get usb cable to connect the box to the pc.
Why do you need to have your tv mounted upside down?
