when i have a Stadia controller plugged in via USB the controllers LT is disabled and the RT opens the systems keyboard.
This happens on EVERY modern samsung phone with the latest ONE UI3.1
this has been an issue for a longtime around 6 months and i think i know the solution but it can only be done with a system one UI update, the solution is to update the button mapping which is in the phones firmware files which is locked without root access.
also updating the button mapping may allow PS5 controller support.
