LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

Thanx very much for your efforts!! I have a question regarding the NikGapps: Which files do I have to download if I only want to have core functions, comparable with the pico package of Open Gapps?

Just core... This is minimal nikgapps package.
But if you would like to use Android auto you have to install that addon as well.

I found a terrible bug:
Call dialer is not working properly, i had to replace it by google call dialer app.
If i try to call someone, i only hear the ringing, i can´t see anything and no way to turn off the call.
Besides that, it´s working flawless i think!

If Im installing the linage os freshly from stock MIUI, I just need to wipe the system and then install the Linage os package? Awesome work, I am glad to see this phone still supported :)

You need to follow the steps mentioned above...
First step, is unlocking the bootloader, then you need to flash the compatible TWRP in fastboot, and then follow the steps, exactly as described above and you will be fine.

    I've flashed lineage-18.1-20220413-signed-pyxis.zip over the january rom, wiped caches, and so far the general performance is just as good as before, the fingerprint reader on the screen gives me the feeling that it has improved. The only thing that has failed me has been the Paypal app, it closes and although I deleted it and reinstalled it, there is no way for it to work. All the best
