Sorry but you're mistaken.
Tried using a DualSense, DualShock4 and an XBOX Wireless Controller today - Only the DualSense is mapped wrong and it's to do with the Android 12 update.
No interest in using PSPlay or any of Sony's remote services, tested the game out on Civ/KOTOR/ShadowgunLegends/Fortnite.
Shadowgun shows through remapping that Android 12 doesn't even see L3 as a "Stick Button", rather assigns it a random number.
This issue is really annoying given that one of the main reasons I bought a Fold was for gaming while travelling.
