I have had the FP3+ for just under 2 weeks now. I first installed Lineage 16 with TWRP, Magisk, AFWall and adaway. Unfortunately, I didn’t test all the functions naked first and then found out that both my camera and my sound don’t work.
Reading in various forums, it seems to be solved in /e/ as well as in 17.1, but even there not with all or in combination with the mentioned apps. I would also be happy to cooperate with the people responsible or one of them who can hopefully do this without gapps. This also applies to 16 ;).
Thank you for your help and your tireless efforts.
