[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] Kartoffl:
Ok first of all thanks for the hard work. I really love the rom.

Here is some feedback for you, also compared to the previous version.

I made a full clean install with the following installation order (used Raupes latest TWRP version)

Wiped everything and also formatted data

Flashed latest developer Firmware from this thread

Flashed the latest RR Rom

Flashed official Open GappsMini (Arm64/8.1/Mini)

Flashed latest Magisk

Flashed Camera2Api Magisk Module

Wiped Cache/Dalvik

Reboot System

The first thing I noticed after setting up pattern+fingerprint is that the unlocking process is completely broken. Most of the time you just get a black screen after unlocking. The problem was that the ambient display was on ALWAYS ON under display settings. Maybe this setting is not compatible with the Mix 2. After turning it off everything worked like it should. Also the option to lift up your phone to show notifications and clock is not working.

After that i encrypted my phone. Everything OK!

Then I Installed the modded Gcam and its working perfectly! (Didn't work for me on the previous build)

Also Double Tap to Wake is working with the new Rom

Sadly the audio and proximity call issues still persists (for me atleast). I'm using the google dialer that came with the gapps. When someone calls there is no audio sometimes and the proximity sensor is not always working. It works now :)

Changing the Accent Color under Theming in the RR-Settings crashes the Lineage-OS Settings and Accent Color stays on the standard one.

Heres the Log for this crash:

Auto Brightness still not working for me It works

The idle battery drain seems to be fixed now, no more battery drain overnight :)

I hope the call issue gets fixed asap. Thats the only major problem imo. The other bugs are only minor, I can live with them :).

The rest is working perfectly (ok VoLTE maybe not, but i'm not using it anyway :)). Really smooth Rom, great battery Life and everything else works great.

Good job!
