I've tried three different controllers and even though they all connect none of them function properly. For some reason none of the buttons work and the screen automatically scrolls to the top and stays there till I disconnect
What controller are you trying out? When using a Bluetooth controller, idk if it's Samsung phones or all Android phones but my last 3 ultras have all been really picky on controller support. The absolute resolution I've found is using either a Sony PlayStation dual shock 4 aka PS4 controller or just using OTG and plugging it in. Even then I've had a backbone refuse to work and some other really expensive controllers. Amazon Luna worked for a while then never worked right again. PS4 was the only reliable one.
