besides the errors already mentioned, I noticed an excessively slow charge, in the previous lineage it loaded in an hour and 30 minutes, this one took exactly two hours. The fast loading message appeared but still took a long time. I would also like to request some customization options in the kernel like lower minimum frequencies and the possibility of undervolt in the future when possible. Great Work is an awesome rom for a first build.
 
Build is surprisingly stable. However I have goint few things.
Pure black dark mode doesn't work.
Mobile network speed is showing 0.00.
Wireless screen sharing causes reboot.
Mobile feels warm to touch.
I know those aren't huge bugs but just to point out. These are the ones I have found so far.
Great work developer thanks Keep it up.
Those are bugs related to lineage itself as it's still a wip as of now.

You could try spoofing your device as non samsung device with https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf
android 12 added more build.prop files in few partitions so you would have to edit them manually too if you wanted to do it that way

thank you for this rom , working perfectly .
i make a video , how to update samsung s7 edge with this rom .
later . i will try other rom lineageos 19 for s8+ and note 8 .
If TWRP 2.8.4 or higher already installed:

Download the latest TWRP image file (.img) from the download link and boot TWRP. Go to install and find and select the Images... button. Browse to the image that you downloaded and select it. Choose recovery and swipe to flash.

Great work! Does this ROM also support microG?

Answering my own question here: It seems it's not (yet) possible to enable signature spoofing in Android 12.

I still tried to enable it, but it failed. I saw that Android 12 is mentioned on this GMSCore page, implying it is possible to get signature spoofing, so I tried this procedure. First flash LOS, flash Magisk 23, then boot and install the two Magisk mobiles "Riru" and "Riru - LSPosed", then install FakeGApps fork by whew-inc (an apk). But microG self-check says signature spoofing is not enabled, and this is confirmed by the app Signature Spoofing Checker.

Tem rosto desbloqueado? Parece bom Ivan, mas, tenho uma pergunta, posso usar ThunderTweaks com isso?
Preciso saber antes que eu pisque.
you can use this app without problems as long as you have root but as it is a simple kernel you won't have many configuration options. i miss the undervolt options

Hello,
Good ROM but huge echo on the caller's side, almost impossible to have a decent conversation. Reflashed twice but I had to revert back to stock ROM to make it disapear.
I've also noticed some impossible pairing on some bluetooth devices (handsfree kit for instance) while my Boose speaker is perfect...
I'll give it another try when it will be a bit more stable.

    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM

    - Mobicore
    - SW codecs

    Not Working
    -


    Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those
    in this rom thread, also do not post bug reports for known issues or bug reports without proper
    a) Logcat
    b) proc/last_kmsg (or proc/kmsg)
    c) data/tombstones
    d) dmesg




    Install gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)
    NikGapps, BiTgapps and FlameGapps were tested and working tho BitGapps and FlameGapps performed better due to more up to date packages

    Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12 support
