Trackpad not working in Android (10 + 11)

Uncategorized
This is very unusual but…
I modified part of the motherboard of a ~2010 MacBook Pro to send the keyboard + trackpad data via a USB cable. I plugged it to different devices and operating systems (all of them detect it as "Apple Internal Keyboard / Trackpad")

Desktop PC / Surface Pro 6:
Bios -> Keyboard works. Trackpad works
Windows 10 -> Keyboard works. Trackpad works ("just" as a mouse… move around and click… no multi-touch gestures)
Linux (Ubuntu) -> Keyboard works. Trackpad works (recognized as trackpad) including 2-finger scrolling
MacOS (Virtual Machine) -> Keyboard works. Trackpad works including ALL multi-touch gestures

iMac 2009 / MacBook Pro:
Keyboard works. Trackpad works including ALL multi-touch gestures

Lenovo P11 Pro (Android 11) / Samsung Galaxy S9 (Android 10):
Keyboard works. Trackpad appears dead. Can’t move the cursor (both devices have a desktop environment) and can’t click.

Please someone help me out here as it literally works on every device/OS (old/new) except any Android devices…
Cheers!
