Mine did not boot at first. I had to clean wipe. But after that it works perfectly! Thank you for your hard work. I have two current issues. Android Auto shows error code 22 and audio quality is really bad. It sounds like the device is stuck in calling audio mode. Even while playing YouTube.
Regarding that camera-related problems, actually there is not much i can do to improve it.

Because SONY camera HAL is really tricky and a bit different from other QCOM devices, so the most i can do for now is just make it "WORK" with basic functions, and as you know the SONY always butchered the camera quality after unlocking bootloader / flashing custom roms just like what they did on their old devices.

My main goal is to make sure that you won't miss any MAJOR hardware feature, but sometimes it depends on vendor's binary files.
Since Z5 owns almost the same device specs of our device, all the issues related will happen to our phone. Please consider the old post @tarkzim wrote in the last year.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community.
