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

Hi Ivan_Meler.
I can't say for sure if this is a bug or not, or if it's a defect in my phone display. At maximum brightness in the black theme, the display is not completely black, but more gray. If you do not push the brightness slider to the maximum, you can get a bright display and saturated black.
Thanks for the incredible firmware!
Happiness and good luck to you.
(I hope Google translated my monologue correctly.)
Greetings from Ukraine.

Enable pure black mode. You can find the slider under settings/display/dark theme See my previous post.

Hello, I found the problem, it was the fact that the anti-flicker was turned on (which is in the LiveDisplay settings), it spoiled the black color for me at the maximum brightness of the display, after turning it off, the black theme revealed its black potential. :)
Thanks for the tips.
Happiness to you!:)

That's correct, as you reported call echo is still BROKEN on S7 LoS, and there are a lot of people who have to discover this for themselves - because it's still not declared in the initial posts (for reasons that elude me, or purely to make the rom appear PERFECT).

I was on Floyd 6.0 for a long time, just tried 7.0 and some bugs are still left - for example camera2 apps often fail to start because Samsung cam seems to block camera access... so I switched back to LoS and the newer Android 12 with more security features.

LoS on S7 leaves a lot of more internal space, battery life/performance is better (esp. using ThundeRStormS kernel) - so it's great if you don't use telephony and run into the echo problem, and need the built-in features of the stock rom - most of them are available with 3rd party apps, except for Samsung cam.
ThundeRStormS kernel is working on los 19.1?

In my device, The browser can not open app. It can't recognize intent::xxx url. I've search about the default browser and it is call jelly browser. But when I try to find out the latest version, I only found v11. This rom use v12. So, I think that is the latest. I like this browser because it's lite. Does the rom maintaince for the browser development too?

guys, can you confirm NFC working with this ROM? I noticed that on first page it doesn't mention NFC in "working section". I also found this post where someone post NFC firmware to fix the issues in previous official LineageOS 14.1:

First of all, thanks very much for your hard work on this.

I'm curious where did you get all the blobs needed for building, as I couldn't find all of them in official ROM. I want to build for myself in order to do experiments.

    Builds with September security update are out, here is a brief changelog
    - Merged September 2022. Security update
    - Updated chromium webview to 105.0.5195.79
    - Synced with LineageOS source

    Not too many changes as you can see as most of work went towards 20.0 builds which are quite stable already.

    18.1, 17.1 and 20.0 builds will be updated with september security update once security patches have been merged to those branches

    Huge thanks to everyone who supported this project with donations that help cover the build server cost and get me coffee.
    Enjoy new builds and stay safe

    @meesam3379: Yes I know there are differences but its hard to find gapps for Android 12.1/12L or SL. Could you please provide a link to a valid version?
    NikGApps Omni 12L
    First Format Data (In case you havent already)

    Then Wipe Everything (System, Dalvik, Data, Cache). Internal Storage can be excluded.

    Install the ROM
    Then without rebooting install the gapps
    Reboot and wait for a while since the first boot takes time

    Good afternoon, all. Can you please tell me why I can't split the screen into 2 apps? Will this be fixed in future updates? (Maybe the split screen method is slightly different from the official Android 8. Or I'm doing something wrong when splitting the screen).
    Happiness to all!
    Regards from Ukraine.
    (Sorry for Google Translate if my text is not clear.)
    **************************
    Всем добрый день. Скажите, пожалуйста, почему я не могу разделить экран на 2 приложения? Будет ли это исправлено в будущих обновлениях? (Возможно метод разделения экрана несколько отличается от официального Android 8. Или я что-то не так делаю при разделении экрана.)
    Счастья всем!
    С уважением из Украины.

    What I really miss in this thread is an advice, which GAPPS work well with this custom rom?
    No luck because error in TWRP 3.6.2_9-0 with:
    - FlameGApps-12.0-basic-arm64-20220307.zip
    - MindTheGapps-12.1.0-arm64-20220605_112439.zip

    NikGapps-omni-arm64-13-20220904-signed.zip is flashable but "google play keep stopping" appears multiple times during first setup of the device. The "Getting your phone ready" circle stops after a while saying "Couldn´t connect", so wifi fails..
    Of course I wiped caches before and after flashing.

    Could anybody give a hint or advice to get it running?

    Thank you in advance.
    Try format instead of wipe DATA and flash ROM and gapps together before start.

    The FlameGApps you used are for 12.0 and this rom is android 12.1
    And the NikGApps you used are for Android 13

    Flash FlameGApps or NikGApps for Android 12.1/12L or SL

    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

    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

    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
    - Removed unused build.prop entries
    - Fixed few selinux denials related to hwc props
    - Improved UI performance and stability
    - Cleaned up source

    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

    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

    Enjoy new build and stay safe
