There is a difference between "11 PRO" and "11T PRO"... The former didn't get the latest security updates which had a patch for the "GOODIX CONTROLLER INPUT" bug...
Many different phone companies like Oppo, Poco, and some Vivo phones are also having this issue...
Its related to a component mislabeled in the motherboard that all of these phones share... Basically the Touchscreen and Fingerprint sensor use a chip which UNITY (the game developer) recognizes as a controller chip...
Now most of these companies have rolled out security patches pertaining to this issue...
In my case, it was luckily the very LAST security update and android update (MIUI Global 14.0.7.0) that fixed the issue for me, and gave me Tilt Controls instead of the stupid non-existent Controller ones...
But for most of u out there, there is NO solution on the default OS... U need to change the OS on the latest version of android 13 or higher and latest version of MIUI 14 or higher...
Sorry but even when my issue had been fixed, I kept looking for a solution, and in the last 3 years couldn't find one...
Here is a link to the OFFICIAL UNITY FORUM where some devs are discussing the same issue... https://forum.unity.com/threads/gamepad-controls-on-mobile-are-detected-even-if-pad-is-not-connected-this-occurs-only-on-2-devices.1196839/
