Inconsistent behavior of Xinput/Xbox gamepads across Android/Samsung devices

Gamepad is my main form of input when playing games on my Android devices, and one thing I enjoyed was the haptic feedback (rumble) of the controller. Prior to the 2023 release of the Samsung Galaxy S23 Ultra (GS23U), I was rocking its predecessor, the Galaxy S22 Ultra (GS22U). A month after its release, I bought the GS23U to see if an upgrade was worth it. When I jumped into a match of Fortnite (supports rumble) I quickly noticed that there was no rumble. After hours of googling and troubleshooting, I concluded that it might have been a quirk of the phone. It didn't matter much as I returned the GS23U anyway for reasons unrelated to controller rumble. Fast forward and I go through the same ordeal, this time with the Galaxy Tab S8+ (GTS8+) and the Galaxy Tab S9+ (GTS9+). Rumble on the last gen, none on the current gen. Pretty clear that the Galaxy devices of 2023 did not support rumble on Xinput controllers (I kept the GTS9+ anyway for the IP68 rating). And now, the present... I'll let the table do the rest of the talking. I tested 3 controllers. 2 Xinput, and 1 non-Xinput. - Same Android version across devices. (Android 14, OneUI 6.1.1) - The only meaningful hardware change across generations is the chipset, Snapdragon 8 Gen. 1, 2, and 3 respectively. - All connected via USB Pretty clear that something changed regarding Xinput 2023 & onwards, and rather than a solution (one would be nice though), I'm just curious as to what's going on. My first guess is drivers, but I'm not entirely sure how that works on Android.
