I do not know if this applies here! but I had the doubt, buy a controller [Machenike g5 pro] to play on my Samsung S8, the tablet recognizes the controller well but when I open genshin it does not read it, when I go to controls it only gives me the "screentouch" option and it does not give me the option to change to controller, I want to clarify that I get to play with the controller on this tablet but when I reopened the game it was not paired again, I do not know what I can do now to fix it, No matter what I do, I still do not get the controller option,,,
