-

Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those

in this rom thread, also do not post bug reports for known issues or bug reports without proper

a) Logcat

b) proc/last_kmsg (or proc/kmsg)

c) data/tombstones

d) dmesg

Install gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)

Since most gapps didnt update for 12L yet (SDK bumped from 31 to 32) i edited falmegapps and uploaded them here use them if you cant find gapps that work on 12L https://mega.nz/folder/FFoS1IIK#XunGRNTViQY7-OZ8oQr0sg

Make sure gapps you decide to use support android 12L/12.1/Are targetting api level 32

Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12 support
