What's working:
Wi-Fi
Bluetooth
Mobile Network (Calling, Data, etc.)
Audio (Stereo Speakers)
GPS
NFC
Camera
Fingerprint Sensor
S-Pen Basics
HDMI
MTP
Call Recording
HWC
Signal Strength
Encryption
What's not working:
Iris sensor does not work because AOSP upstream does not support that yet.
IMS services (VoLTE, VoWiFi, etc). Samsung has their own proprietary implementation. It is not really possible to easily port that to LineageOS.
Bugs:
S-Pen/Mouse will cause small graphical glitches during button animations sometimes.
Instructions:
Make sure TWRP has been installed and is functional
Download the latest build and CSF9 vendor.img (optionally gapps and magisk if needed)
Reboot to recovery
Wipe data and cache (required if you switch from other ROMs)
Flash the vendor image
Flash the latest build (then gapps and magisk if needed)
Reboot
How to update builds?
Do not wipe anything unless stated in the changelog
Flash only the rom.zip and it will automatically reinstall your gapps, magisk etc
use /system/addon.d if you would like to keep system mods after an update
