I have no idea what you do with your devices. The current version (vanilla) runs so smoothly fast for me and without consuming too much battery. It is a pleasure to use the device! Great work @Ivan_Meler ! 👍

Installed twrp-3.6.2_9-0-herolte, lineage-20.0-20220919-UNOFFICIAL-herolte, NikGapps-core-arm64-13-20220908-signed, Magisk-v25.2 I installed everything that I usually use, everything works fine, smoothly, without errors, except for the backlight of the buttons, but this was mentioned. The only problem that does not allow you to use this firmware, when the interlocutor hears himself, he has an echo. This problem is probably on all custom firmware and it can not be solved in any way. It is extremely inconvenient to use because of it. If there is a way to fix this, please let me know.

The echo issue was fixed in LineageOS 19.1

I'm sorry to have to disagree with you, but the echo problem is definitely not solved for everyone. LineageOS 16 is the highest version under which the echo does not occur for me. I have just tested this again with the latest version of Ivan.
Perhaps the only reason you read less about it in the forums is because those people who have an affected S7 have resigned themselves to the fact that there will be no newer LineageOS versions usable in their cases (at least not for making calls and keeping friends at the same time). ;-)

Recently I tried LineageOS 19.1, there was an echo, so I did not try again. I've been using LineageOS 20.0 for several days now, everything works very well, the battery keeps well. There are no serious shortcomings. The browser could not access the memory when downloading the file, and did not figure out how to fix it, put Chrome, there is no such problem. Unfortunately, the interlocutors constantly complain about the echo, so I'm waiting for the problem to be fixed, I don't want to return to the original firmware, but I don't see any other alternative.

New builds are out, here is a brief changelog
- Added button backlight control
- Unpinned deprecated updatable media apex jar from ram
- Allowed system to override some bluetooth props
- Performance and stability improvements
- Synced with LineageOS source (Almost all of lineageos features should be there and work now)

Almost all of the lineageos features have been ported to Android 13 now and are working, there still might be a missing few compared to android 12.1 like toggle for software buttons which is work in progress at the moment.

There are also some device side changes that should improve performance stability and battery life

Huge thanks to everyone who supported this project with donations that help cover the build server cost and got me coffee which helps speed things up.

Enjoy new builds and stay safe.

Yes, also my thousands thanks to you @Ivan_Meler for your efforts, its a great job, what you are doing, you are a genius.

I read, that you do this in your free time beside a regular job... thats real rage for keeping up the free Android on the Samsung Galaxy S7... great thing, very great thing!!! (y)(y)(y)

I will change to your LOS 20 in a few weeks, actually I am (as an elder handicaped person) not fit enough to sit the several hours doing the change and then configuring the S7 complete new again...
But I will be better in the next time, I hope, and then I'll gonna get the bull at its horns... :cowboy:

Reading here helps me also to learn a lot, this XDA forum is great, thanks to all too, I really appreciate that!

But one thing is to ask: how can I transmit you @Ivan_Meler a little donation? I ask, because I do not use the PayPal. If you have an idea, please give me an private message.

    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

    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.

    - 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
