Confirmed Android Controllers
From reading through the forum and searching online it seems there is no controller that is confirmed to be working on Android for now. Perhaps the soon to be available Gamesir T1D will be the first.
If you have any other controller and can confirm that it is working please let me know and I will update the list.
