Good question. I didn't try them yet, so I'm not completely sure what we need. Also, it's not mentioned anywhere how we should install them, all of them, or in some order. Maybe we need just the core. I'm a little busy at the moment, may try to give feedback later.

I have also installed it in addition to Magisk and FlameGapps with no issues at all and it runs super smoothly just with a few little lag spikes here and there, but that's totally normal and could just be my phone getting hot 😁

Also, @Synt4x.93 Just wanted to let you know that I linked this forum post on the Custom Android 11 rom list.

EDIT: NEVER MIND THEY ALREADY ADDED IT

Haven't used a custom rom in a while (last was for Nexus 5X and Samsung Galaxy S4). Is the camera quality the same with this ROM compared to stock?

For me, WiFi does not work. My device scans and finds the network correctly but doesn't connect. No error message whatsoever. After dirty flash from Lineage 17.1 I did a clean install, too, but that sadly didn't change a thing.
Any ideas?
EDIT: Alright, found it. I installed the 2020-12-16 version at first, with the 2020-12-18 everything is ok.

This rom is amazing, smoother than any other rom I ever tried, definitely smoother than OneUi by a long shot, everything works :) I seriously recommend installing it, my battery life went from 2 hours SOT on OneUi to 6 hours SOT on this rom THANK YOU SO MUCH DEVELOPER, we haven't had any new roms lately, specially Android 11, seemed like everyone else had an Android 11 rom but us

Thanks it's works.
Anybody has success install and run "props" with magisk hide props ?
I use Termux but no SU notification... and command "props" is missing on shell.

Same things for Call Redording, no settings in call apk

Frustrated,because the Rom is awesome !
