After installing this ROM, does the ROM get updates automatically (like regular android os) including security updates - or has does this need to be manually done each time there's a release provided here ?

Also, if manual, is there a process without wiping the installed apps & data ?

Is there a way for you to provied us with option to enable AC3 and EAC3 audio codecs?

From what I have read to use those codecs you need a license from Dolby so they were disabled by default in LineageOS. They were implemented in OneUI Samsung roms I used before.

Hi man, I'm also new at this and after a quick google search to see how I can dirty flash this December update, I found that people generally agree to do a Dalvik and Cache wipe in TWRP and than install the new ROM over it.

I did that and got a nice case of the good ol' boot loop, which in turn dosed me with a nice amount of the good ol' cortisol. After trying to make sense out of it, I managed to figure out that you also need to flash gapps over it and magisk if you use it.

Now everything is up to date and working as it should. No data on the phone was deleted and all my settings remained the same.

TLDR - To update ROM
1. Wipe Dalvik, Cache
2. Flash ROM, gapps (bitgapps_arm64) & magisk if you use it.

This worked for me flawlessly. Hope that helps.

I can confirm #17:
Upgrade from latest 18.1 with BiTGapps worked well:
Flashed latest TWRP - 3.6.0_9
Wiped system, cache, Dalvik, but not data
Installed lineageos 19, BiTGapps, Magisk 23, flawless reboot into system
SaftyNet test success

Great job, Ivan!

Hey Ivan, thank you for this update. I found the following issues (compared those with another Android 12 device):

1) the date on the lock screen should be a bit more up near the top of the screen (with no notifications shown)
2) the clock color is accent color and should probably be white as it looks out of place
3) in the app drawer, the app search bar is partly on top of the first row of apps
4) after using the app search bar, filtered apps won't come back after removing the search term

Not sure if you can do anything about it, those are probably all LOS related.

Edit:
5) Touch gestures are sometimes difficult to trigger, e.g. unlocking the phone, swiping notifications, etc.

So I wiped it again, this time I also selected the system, because I felt that maybe it could help.

Now everything is up to date and working as it should. No data on the phone was deleted and all my settings remained the same.

TLDR - To update ROM
1. Wipe Dalvik, Cache and System
2. Flash ROM & gapps (i use the recommended bitgapps_arm64)

This worked for me flawlessly. Hope that helps.
thanks for responding.

When selecting "system" in TWRP to wipe, wouldn't it remove the installed apps as well ?

Huh, really weird. I've actually noticed my playstore is not connecting to the internet. I can search apps, but when trying to download, it just say pending and in the playstore app manager it says your offline check your connection.

I've tried clearing playstore data/cache, uninstalling and re-flashing the rom, but nothing seems to work. Anybody has any ideas?

@spec_au that is correct, there are no automatic updates. You have to download the rom and flash it again.

Happened to me too. Someone said a reboot fixes that so I tried rebooting but I still had the issue. Then a day later it just worked (after another reboot). I don't know what causes it, but you can try a few reboots and be hopeful.

Hi,
could you please clarify GAPS flashing.
Ivan wrote:
"nstall 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)"
In the bitGAPS docs you can find:
"Standard Installation:
Installing BiTGApps from recovery. No feature enabled in config. But config is still there in internal storage.
Usage:
Install ROM
Reboot to recovery
Install BiTGApps/Addon Package"
and
"Avoid installing BiTGApps just after flashing system image. Instead reboot to recovery or reboot to system then install BiTGApps packages."

What is the correct scenario?
Flash GAPS right after ROM or
Flash ROM than reboot to recovery than flash GAPS.

Or do not take into head, both are ok? :)

Thanx.

I have moved from 18.1 to 19 and have found that...you need to ensure you have flashed latest TWRP - 3.6.0_9
dirty flash .. Wipe cache, Dalvik...
Install lineageos 19, BiTGapps or NikGapps (and any other add ons...I did Android Auto for NikGapps)
Install Magisk 23
Then reboot System....
As 'usual'... Ivan's ROMs...are pretty good...so...suggest...buy him a coffee!

Hi,
I was on FloydQ for a quite long time and now try to move to a12.
Very very nice,
but the echo issue makes me very sad.
When smbd calls me he hears his echo and it makes simple sound call nearly unusable for my opponent.
I tried PE12 - the same and the most sad, that this is "due to samsung sound driver which cannot be implemented here. Never."
Will try to move to Ivan's A11. Is there also echo issue due to "samsung sound driver"?

unfortunatly, if u want no echo, u need to use stock rom.

    Here we go new build is up and here is the changelog (I also "fixed" mess google made with phone services notification which was affecting a lot of devices and wasnt device or rom specific)
    - Switched to new libperfmgr power hal which can be configured from /system/vendor/etc/powerhints.json
    - Adapted DT2W to new power hal
    - Muted phone services gps notif (Thanks google really appreciate you breaking random things for everyone)

    - Cleaned up all of leftover patches that were used by legacy power hal
    - Synced with LineageOS source

    This update has new power hal which took quite a long time to get working properly
    It also outperforms old one and battery life is also better with it since it handles power management way better
    Huge thanks to everyone who supported this project and got me coffee while working on this thing

    Also huge thanks to everyone who donated and helped me cover the build server cost as they are the reason this project is still alive

    Enjoy new build and stay safe

    Here it is May security update with few changes related to device too
    - Improved battery usage logging for display
    - Added QR code reader to camera app (Long hold icon and launch it from context menu)
    - Misc performance and stability improvements

    I also continued work and testing of new power hal ive been working on for past month or so, Hopefully ill release build with it in a few days (If time allows me as i do this in my free time as a hobby)
    Power hal seems to perform better and manage battery life and performance way better than curent one but i would like to test it further before releasing it

    As always huge thanks to everyone who supported this project and helped me cover the build server cost which is one of reason why this project is still alive keeping s7 up to date with software, New power hal will improve things even further so i cant wait to release next build with it

    Enjoy new build and stay safe

    Hello,

    the installation worked for me. However, I do not get further with the setup.
    But after the pin input I come back to the Google Services screen. After two repetitions then crashes with the message settings keeps stopping.

    Installed packages:
    lineage-19.1-20220427-UNOFFICIAL-herolte
    NikGapps-stock-arm64-11-20220421-signed
    Magisk-v24.3

    Where could be the problem?
    How did you manage to install 11 gapps on Android 12? That is your issue

    LineageOS 19.1 for herolte

    Code:
    /*

    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    - Wifi
    - Sound
    - mali drivers
    - USB tethering
    - HW Backed video Playback
    - Ril (Mobile data,calls, sms and stuff)
    - Sensors

    - Charging with device powered off
    - Stuff I didn't test yet
    - Camera
    - GPS
    - Fingerprint Sensor
    - 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)

    Since most gapps didnt update for 12L yet (SDK bumped from 31 to 32) i edited falmegapps and uploaded them here use them if you cant find gapps that work on 12L https://mega.nz/folder/FFoS1IIK#XunGRNTViQY7-OZ8oQr0sg
    Make sure gapps you decide to use support android 12L/12.1/Are targetting api level 3212L/aka 12.1

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

    - Fixed issue where camera would stop working after prolonged use
    - Misc performance and stability improvements
    - Merged some more lineageos features that have been posted to gerrit
    - Synced with LOS source

    keep in mind February security update has not been merged yet and should be in a few days so ill post new build once security update is ready

    This really took a long time to fix properly (almost 2 years i would say) especially without disabling fdsan system wide
    This fix will be ported over to 17.1 and 18.1 builds too but before i release them ill hold on till february security update is out

    Next thing on my todo list is to somewhat mitigate echo in calls some users are experiencing

    - Fixed ok button which would go missing for button backlight
    - Switched to source built secril_config_svc (used for ds detection)
    - Removed obsolete debug.sf.disable_backpressure prop
    - Merged latest security updates to kernel from aosp kernel/common
    - Cleaned up source
    - Cleaned up unused props
    - Removed unused custom ld.config.txt that was overriding main one
    - Misc performance and stability improvements
    - Synced with LOS source

    there are quite a bit of changes this time around, biggest being that selinux is now enforcing once again.
    Once again big thanks to everyone who supported this project so far as their donation help cover the build server cost and get me a coffee.
    There might be few more updates in the coming days if i find anything device side that needs improvements as i have to stay home anyway so might as well do something productive

    enjoy new build and stay safe
