Since Genshin Impact came out, a lot of forum questions and articles popped up about playing the game on Android using a controller. A few years ago, all the answers were like "only the console, PC and iOS versions of the game support a controller", which was quite disappointing. From what I understand, the reason is that users could use external Bluetooth devices to cheat at the game.
I looked it up again recently and the results seem to have changed: different articles and Reddit threads mention using a third-party app like Mantis or the Razer Kishi to map controller inputs to the game.
To me that sounds like a good solution, however people say (Reddit, HoYoverse forums) that you can and will get banned for using such an app.
I would like to know if this is real, if anyone here succeeded in finding a way to play Genshin Impact with a controller.
Owning a powerful Android tablet, I would be very happy to play the game on it as I barely use my computer these days.
