Hello, thanks for your reply.
Yes, magisk works but now is giving me problems, as i said before and i don´t know why... I like to root the phone, because with root i am able to install modules and manage the phone at 100%, i can use titanium backup for full backup of apps and etc, without root i can not do that.
Yes, before i was using buffer fix for google camera work properly, and now i know why 48MP stopped working. :)
Do you know any good version of google camera, that i can use with your ROM, without messing up with the MIUI Camera?
Thanks in advance.
I think that some gcam V6 does not need buffer fix.

Hello!
Thanks for you reply, but unfortunately i can not manage to get the Gcam working well, lags...lags, and more lags...
I tried different xml config files, different gcam versions, and none of them works well and i don't understand why...
I think i will give up!
For that version you need to flash buffer fix for Android 11. But this affects MIUI camera (typically frozen viewfinder after shot in 48mpix mode)

Already tried Gcam version 6, and others that doesn´t require buffer fix but no luck, anyway... I really don´t understand!

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

Ist there a way to get the notification led working in other colors than white?


I have also noticed that the quality of the pictures taken by the camera varies greatly depending on the application used to take them.
For example, pictures taken directly from Threema are worse than pictures taken with MiCam.


Will there be the possibility of OTA updates in the future?
I set up a device for a friend and sent it to him, but unfortunately I no longer have physical access to the device. Would still like to be able to install new versions though.

Absolutely a great ROM! Financial and streaming apps working flawlessly without rooting.
The only problem I'm having is with the Hyundai Bluelink Europe app. It continuously restarts after giving permissions. Could anyone try this app out for me? Hopefully it's just my setup.
Many thanks in advance!

How is the battery life on latest update? I've been using MIUI 12.1 xiaomi.eu 20.9.3 for a while now. Battery lasts only half a day with just browsing internet.

Thanks again for this amazing ROM. The stability and battery life (2-3 days, SOT 4-5h) are very good. The fingerprint sensor works most of the time, but if the battery is low (<20%), it sometimes doesn't work for me. Camera is perfect.

Thank you so much ceracz! You give my phone a second life after the MIUI support end. I flashed the Firmware, latest ROM and NikGapps-core to my Mi 9 lite and nearly everything works fine and very quick. I found two issues so far:
  1. A minor one: install of the Microsoft Office App failed (I tried it twice directly out of the playstore). Not a problem since there are many alternatives but just to share the observation.
  2. A significant one where I need help: the positioning does not work in Apps like Google Maps, Organic Maps etc. although the GPS sensor obviously works fine and I can see with GPSTest many Satelites, correct coordinates, altitude,... Phone reboot and other easy potential fixes did not work. Any hint how to get GPS working in the Apps would be appreciated.

I was able to fix the GPS positioning issue meanwhile by activating the Google positioning tracking. Not really what I wanted to do and for former Android versions it was not necessary to activate it but obviously now....
Anyway - this is an outstanding ROM, which is stable, quick and providing in my usage profile about 20 % more time per battery cycle than the MIUI12. :love:(y)(y)(y)

Double clicking the power button from the lock screen opens the camera app behind the lock screen. I found no option to open the app without unlocking.

    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.

    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 :)

    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!
