Just finished installing LOS 18.1 with pico OpenGapps (no Magisk, no microG). Everything mostly appears to be working, including WiFi and GPS. Haven’t tested NFC yet. The auto brightness issue is almost unnoticeable, it just went down to lowest brightness once so far under normal daylight.
Edit: NFC appears to be broken for me based on testing with the german ID card. I can’t get it to read the card even with the bumper and the back cover removed.
