@nprofile1q... @nprofile1q... @nprofile1q... @nprofile1q... @nprofile1q... No, that's completely untrue. Android moved away from requiring downstream changes to the Linux kernel years ago. Modern Android works with mainline, stable and LTS kernels.

Android has branches of the upstream LTS kernels with additional backports but also works directly with the upstream LTS kernels. The minimum kernel version for a major Android release is higher when using an upstream kernel since they backport and depend on features.
