hello all, i tried to look for it but its very difficult.

Anyone knows how to install Set Orientation on LC-UE630X with Android ver 6.0.1?
I know abt the apk files downloading and running install but the apks i have downloaded cannot be installed because the install word is dimmed. Anyone can help pls? I can run Astro on the Go but it is like 90deg tilted and i cannot scroll to see other channels. Much appreciated.
