but still: the people who are involved in custom roms do a very good job! pretty much everything works!
What I know - many AOSP / CM maintainers / developers are using signed, proper drivers straight from Sony themself. Specially after Sony did become friendly toward the open source scene..
It's the opposite direction on Samsung devices though what I know that got horrible manufacturer support.
Android Devices that I am using:
1. Sony Xperia Z1 - ROM: RomAur v9.1 / Kernel: Unofficial Doomkernel v21 with 4.4.4 support[/I]
2. Sony Xperia Tablet Z - ROM: Tweaked, debloated & rooted stock 10.5.A.0.230 / Kernel: UnleaZhed XTZ v0.2
