A family member of mine got a new Android tv. It's our first one and I don't know how to set some things up. I got an app that works as a mouse but it doesn't work on the TV owners mobile. It's not supported on his mobile which is weird because it's like a recent one. I tried another app which has great rating can't remember which but it requires enabling an accessibility service. System -> accessibility under the service tab. Weirdly enough there is no service tab in our android Tv so I can't enable the service for the app. Same thing with Android remote app. How can I make the service tab show? Or is there any other app that works?
