I liked playing Street Fighter 4 on Android, one of the few fighting games to offer a full controller experience, I also have a clip on bluetooth controller, but not played much on Android for a couple of years. Had hoped the clip on and phone would act as a handheld gaming device, but too many games only use touch and don't include native support for gamepads. I found mostly racing to offer the best pad support, so many games should have had it but only used screen swipe controls instead like Tekken 7.
There's a lot of wasted potential for Android to have a been a much better gaming platform than it currently is.
