MIUI 13 Gamepad OTG support


Feb 6, 2022
Hello guys, almost 3 years using Oneplus 7 Pro and decided to buy a phone without notch (rare on this days, most part are gaming phones). I received a MIX 4 few weeks ago, unlocked bootloader and installed xiaomi eu weekly, i notice this system a bit unstable with some apps aswell.
I tried connecting my Rumblepad 2 with a OTG cable to play some emulator games, gamepad is detected but can't map any key (was working perfectly on OP7P), is this a problem of latest android or miui?
