HI @Sheeds
The known issue is only related to the official RPi touchscreen, it should also be fixed by now.
The Android Notification can be removed by disabling developer messages:
It doesn't impact performance, it's more of a configuration hint.
As for your touch issue, I couldn't find an explanation in the submitted bugreport. Maybe some kernel modules are missing, but that's a wild guess. As we don't have such a display at hand, I cannot really tell. You can install Raspberry Pi OS and check what kernel modules are loaded when the touch is connected.
Fastest way would be to rebuild the kernel yourself with the needed modules and exchange it on the boot partition. Our kernel can be found here: https://github.com/emteria/kernel_brcm_rpi
