This doesn't seem to be a stable build, you call it "Signature Spoofing", what do you mean by that?
Signature Spoofing is a feature required by a very popular open source app called microG, which allows the user to use apps that require google services without actually having to use google apps.
There is a very clear explanation of signature spoofing here, but be aware that signature spoofing is a contentious feature, and the blog post linked is opinionated.

Thanks for the info, i will read that.
I heared about microG but didn't know it's releated to signature spoofing.

So signaturespoofing is mandatory for using microG ?
Anyway, i preffer not to use microG, nothing from google at all is the best choice... (opinionated i guess...)

So will all the future builds be called signatue spoofing instead of alpha beta WIP or stable?
I asume, it will say somewhere if the build is stable or not anyway?
I'm on LOS 19.1 was thinking to update to 20.0

Can anyone confirm nfc is working? It doesn't work for me but it could be because I've opened the back so many times in the past...🤷‍♂️

Hello,
as far as I know, Ivan's (@Ivan_Meler) sources are also used by Exodusnick for his microG version of LOS. I am still looking for a solution to the echo problem that exists from LOS 17 onwards at least for a part of the S7 devices, so I did a file comparison (all files with "audio" or "mixer" in the name) between LOS 16 and LOS 20.

Unfortunately, I know far too little about Android. But maybe a developer can see a possible cause for the echo problem from the differences in the files, which we can then work on further. For example, I am surprised that the file audio.primary.universal8890.so is missing under .../hw/lib64/, although the S7 has a 64-bit OS (at least I think so).

I would be happy if someone takes the time to have a quick look at the comparison. Maybe we have overlooked something quite obvious so far.

I think it's such a pity that because of the echo you can't use all the new ROMs in everyday life and have to stay with LOS16.

Thank you
kjoe
sorry to say but that comparison of files you did is completely pointless and useless, trust me if it was as easy as comparing files somebody wouldve done it

Excuse me. It was not my intention to mess up this forum with useless posts and to take up your time. I have therefore deleted my post.

However, from my life experience so far, sometimes it really is the simple things that we don't think about.

My apologies once again.

dont you think comparing binary files where source for every file is available is a bit counter intuitive, let alone the fact you didnt compare actual files and just their existance and that you didnt even compare actual audio effect files, i really didnt want to have to explain this for i dont know which time but you were sort of pushing it

Here we go, November security update is out
- Merged November 2022. Security update
- Misc performance and stability improvements
- Cleaned up patches source
- Synced with LineageOS source

Some of you might have noticed that there were not any updates after security update, I had a lot going on in personal life and havent had time for android unfortunately hopefully that changes soon so i can finish up few more things that need to be sorted on s7.
On another note updated 19.1, 18.1 and 17.1 builds will likely be out next week
Huge thanks for everyone who supported this project so far as their donations help cover the build server cost.
Enjoy new builds and stay safe.

To everyone who is facing the issue of apps not opening, I isolated the cause to be formatting SD card as internal storage. Right now you can only use SD card as portable storage.
Well, thats pity!

In LOS 19.1 this works properly, and just this feature makes the S7 with its low internal storage really usable.

So, actually myself I cannot change to LOS 20.0, because I really need this feature (SD card be formatted as internal storage).

Friendly request to @Ivan_Meler : Is this an issue maybe to be fixed quickly?

Well when i remember correctly Android scratched the possibility to use an sd card as internal storage or changed some internal stuff that broke it on Android 13.
If it was easy to fix ivan would do it.
Remember he is doing it as an hobby and has probally other prioteries

As working long time in the IT, I know really good, what a tremendous great work @Ivan_Meler is doing.

My Samsung Galaxy S7 with LOS 19.1 (Android 12) works properly with an SD card formatted as internal storage, and I do not know about, that in Android 13 the manufacturer (Google) has changed that.

I am also very sure, that Ivan really knows by his own, what to do and when to do, and furthermore, as a grown up man he really does not need a warranting spokesperson.

    Users of this ROM, could you please tell if the ROM still has phone call issues like the last LineageOS ROM's?

    Went back to stock ROM after previous version of LineageOS gave call issues which i cannot daily this phone with main feature i can't compromise

    If so i'll need to find a custom ROM without call issue that's all i ask

    No points of updates if one of the main features of a mobile phone is broken
    Echoes only seem to occur on some devices (possibly depending on factors such as hardware or provider, but no one seems to have been able to narrow this down yet). I think you can only find out by trying the current rom yourself. In my case, unfortunately, there were echos that were not acceptable for my phone call partners, which is why I continue to use LOS 16. Fortunately, Exodusnick still includes occasional security updates in his builds based on LineageOS 16.0 with microG, so at least the security risk is addressed.

    Maybe the target sdk of your app? LOS20 is SDK33.. sometimes compatibility for older apps is depends on rom support.
    How can i check the sdk of the app? The app has no problem on android 13 on different phones and on different roms, like pixel experience.

    First post, so be gentle. Today did my first android upgrade. Using this forums information. Unfortunately using the Lineage OS 20 I had a lot of problems, probably network problems. Although 4G did not give better results. I now upgraded the Oreo to Lineage OS 19.1 and all seems a lot more stable.

    I read about wifi problems on some S7's, but I expected this to be in any LineageOS version, but it seams Android 12 is working better than the 13 :)

    may I ask you all onetime more, if the problem with SDcards in LOS 20.0 is now solved?

    No problems so far with a 32GB-sized SDcard formatted as removable storage in the newest LineageOS 20.0 build from OP.

    - Network trafic monitoring (WIP, same reason as bellow, uses BPF)
    - BPF specific functions like fancy new GPU monitoring in Android 13


    Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those
    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 have been updated to 13, you might need to clean flash if you used other gapps in past including nikgapps 12.1 version

    Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12/13 support
