Maybe a clean install will fix it. I have had it multiple times stuff just didn't work until I did a clean install.

Also keep in mind Ivan still has a day job besides this. he still does this in his free time. so if he doesn't respond he is probably busy working.
thanks for your answer
fixed this

magisk and Zygisk

Zygisk cannot activate on some old Samsung devices with old kernel (3.19-)​

For some old Samsung devices, there's a kernel restriction that whenever exec an ELF from /proc, the process can no longer call some systemcalls. For kernel 3.19+, the workaround is fexecve, but it does not exist for the old kernel. Users with those devices should use a custom kernel bypassing such a restriction or a newer version.

are you planning to update the kernel any time soon?
or know of a custom kernel for this rom?

New build is up with few new changes
- Added QR code reader quick settings toggle
- Improved device performance and stability
- Added Custom low power mode power profile for cpu
- Improved A-GNSS (A-GPS) Lock speed
- Exposed device hw revision to settings
- Improved fast/slow charger detection
- Synced with LineageOS source

As always big thanks to everyone who supported this project so far as their donations help cover the build server cost and get me coffee which keeps me up while working on this project.

Expect builds with even more improvements in near future as im testing some exciting changes right now.

Enjoy new build and stay safe

Take magisk 24.1 and all is well. Why break your fingers on the kernel when there is a working solution?
i am on magisk 24.3 there is no working solution except a upgraded kernel.
it is a kernel issue and will never be addressed by the magisk team.
(they have labeled it as "wontfix" https://github.com/topjohnwu/Magisk/issues/5395 as its a mostly samsung old kernel issue)

if you never plan to fix it with a newer kernel then zygisk will never work.
amd magisk has stated that zygisk is the future of magisk

that is the developers choice. if you don't care thats your prerogative

Hi!
This ROM is not your choice if you wish quality voice as stock firmware has.

No solution and no chance to fix it as who claims of bad voice are small part of all S7 users.
The most say that have no such problem. To be honest I don't believe them, as hardware part is the same.

Sad but true (
The problem with voice call quality only happened after the January build since before that there were no issues. I kinda hope someone still has a December build laying around so i can take a look at what changed between those 2 build and maybe revert the change.

It's sad the audio quality is such ****e since the ROM itself is fantastic

Here was asked for such unaffected build already, but without answer, unfortunately.

I suppose only @Ivan_Meler has whole history of builds.

@Ivan_Meler , could you share this magic build without audio issue?

All new additions and changes are must have but only one this fix is worth more than all of them for some of us.

I've been enjoying using this since March, but not too long ago I noticed that new updates were released, so I naturally tried updating. After trying a dirty flash and realizing that it does not work, I've came here to ask, what is the best way to update without losing any data? Thank you for your great work :)
(Edit: I've got the March 10th, 2022 build)

there were no changes to audio in january build tho, except for moving audio lib to vendor folder which changes nothing at all, so if you feel like complaining go fix it yourself and make sure it keeps working on all revisions of s7 samsung made

I always sideload the update, didn't fail once.

I always sideload the update, didn't fail once.
Is there any advantage - concerning the update (new build of identical version) or upgrade (e. g. Lineageos 18 -> 19) process itself on the phone - of sideloading a new build via adb instead of using TWRP to flash the zip file(s)?
I am thinking about switching from 18.1 to 19.1 and wonder if sideloading might circumvent problems coming with the TRWP way, since most guides mention sideloading instead of flashing in TWRP …

I can confirm that one of the January builds was OK regarding voice calls quality.

    Here are some great news for future o this project and s7 on newer android versions in general
    Huge thanks for device donation goes to Exodusnick, I recieved device today so ill be able to properly test stuff with fully working s7 instead of my old broken one which had to be used with scrcpy.

    I already started work on porting some new hals and resolving some issues that were harder to debug before.
    New hals should speed up the device quite a bit without compromissing battery life (might even improve it a bit).

    Also big thanks to everyone who supported this project with donations and helped cover the build server cost and got me coffee in the past, this project wouldnt be possible without them.

    More exciting updates coming soon.
    17
    here it is August security update
    Nothing major in this one as i am still working behind the scenes on that huge update i talked about previously which involves rewrite of almost whole graphics and media stack (its almost finished but i still have to do a bit more testing just to make sure there is no regression)

    In other news android 13 should be released next month and since there were no major changes s7 should be running it soon after release with not too many issues and ill try to take a few days off from work to get it up and running on it once source is out

    Once again huge thanks to everyone who supported this project, helped cover build server cost and got me coffee with donations.
    This project wouldnt be alive without them as i do this in my free time as a hobby.

    Enjoy new builds and stay safe
    17
    Another progress update after another day of work on this
    Here is list of the blobs that we are now source building instead of using proprietary prebuilts from samsung
    thats almost whole media and graphics stack

    this is important for future of device as it will give us full control of whats running on device
    and I or anybody else for that matter will be able to patch any security holes coming from those parts or generally improve them
    or make changes needed for next android version to them

    (Once im done with graphics and media ill work on source building stuff related to ril

    QlxSDJu.png


    Tho ill pause work on this for next week as im going on a short vacation/trip but once im back ill continue work on it and if everything goes as planed post builds using new hals and source for them

    As always huge thanks to everyone who supported this project by covering the build server cost and buying me coffee
    16
    Another quick progress update since im back from my trip
    One of bigger issues with new rebased hwc source has been fixed (I fixed it and tested fix 2 days ago actually but didnt post anything about it) and rest of the issues have been logged

    This just leaves 2 issues related to scudo in new OMX stack and 2 or 3 edge cases in hwc stack
    after that new and improved source will be ready and it should bring quite a bit of improvements to s7 on aosp

    Big thanks to everyone who is helping to cover the build server cost and coffee spent on this project.
    11
    Here are some progress updates, I got working s7 2 days ago as some of you know from following this thread and i made some progress (actually quite a bit of it)

    New graphics stack is running on it already i just finished up few commits that made it boot up with it (its 1am in my timezone now)
    It will still need some cleanup and fixes and testing before it goes public but with this we will replace quite a lot of propretary files with more modern and up to date with open source hals

    Once again big thanks to everyone who helped cover the build server cost and got me coffee which helps during night developement haha

    More updates soon..

    - 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)

    Make sure gapps you decide to use support android 12L/12.1/Are targetting api level 32
    Also make sure you are using latest official TWRP before installing rom older versions do not have proper android 12 support

    If you want to use Magisk use latest Magisk Beta (25.0) or Magisk 24.1, there is bug in 24.3 that was fixed after its release that prevents zygisk from working on some devices with 3.18 kernel

    Since my birthday is tomorrow I decided to release a little surprise build. Here is a brief changelog:
    - Updated libexynosdisplay from BSP to comply with some android 12 changes

    Im aware of Seedvault issue curently present and im working on a fix for it.
    I wanted to release something as a gift from me to everyone using this rom and supporting this project throughout the years. Keeping older phones alive and up to date is really fun hobby and I don't think I would've kept doing it if it wasnt for all of the support from the comunity.

    Once again big thanks to everyone who helped cover the build serve cost and coffee.

    Enjoy new build and stay safe
    22
    New build is up, here is a brief changelog
    - Merged July 2022. Security update
    - Fixed more keystore issues
    - Synced with LineageOS source

    Also some important news, Exodusnick decided to provide huge help and he bought and shipped s7 to me which should be here next week, so all of exciting updates i talked about last week should be way easier to achieve and this will make testing and developement a lot easier, Once again huge thanks to him.

    Also big thanks to donators that helped to cover build server cost and got me coffee which helped to keep this project up and running.

    Thanks to this s7 should live for few more android releases without any major issues. and Android 12 will get even better with new hals that are curently in developement

    There will be updates to 18.1 and 17.1 in a few days once july security updates have been ported to them

    Enjoy new build and stay safe
    22
    Here are some great news for future o this project and s7 on newer android versions in general
