So congratulations to the guy who made it possible to run Android 11 with that ancient Linux kernel, even when Android officially doesn't support it. And to illustrate what I mean by ancient: Linux 3.0 was released in 2011 and got support updates until 2013 [1]. So even when CyanogenMod/LineageOS supported the Samsung Galaxy S3 the included Linux kernels were old as crap. You can't blame them for it, as they had little choice given that a few crucial drivers are not open source and included in the upstream Linux kernel.
I just wonder if anything has changed for modern devices?
