maybe there is better gcam.

if anyone knows, please share.
For A52, I find the LMC one a bit better, with BSG Morgenmann XML file. They're in a pinned post on the telegram group. It has more settings and Auto-White Balance works better than on the BSG Gcam. However I agree that not being able to capture 64MP shots is disappointing. However I did try the stock camera before flashing Lineage and the larger resolution picture helps but the quality of the 64MP pictures is not overwhelmingly better than what Gcam produces (16MP) or the non-64MP mode on the stock camera (also 16MP I think).

I can also report that microG works absolutely fine with the latest build on microG page: https://download.lineage.microg.org/a52q/lineage-19.1-20220915-microG-a52q.zip

the date version 2022-10-08 extremely good. More battery saving, more stability. I believe it is close to the final version.
I think the latest builds are just auto-generated by Lineage right? I thought I would be able to get those changes through OTA but I see no updates are available unfortunately. Not sure when something will be available via OTA updates.

Are you on an official lineage build already? (anything newer than 20221003)
Because you will only get OTA updates if you are on an official lineage build, OTAs won't work on the old unofficial ones.

Así que obtuve mi A52 y comencé a instalar la ROM hoy. ¡Gracias por su apoyo hasta ahora!

En TWRP, después de flashear multidisabler, flasheé Lineage (originalmente probé la compilación microg, luego probé la última noche), sin embargo, el sistema no arranca. Vuelve a la recuperación si intento iniciar el sistema. Usé el TWRP vinculado en tu publicación original @Simon1511 .

Intentar borrar Dalvik/ART Cache o Data en TWRP muestra los siguientes errores:
[CÓDIGO] No se puede montar /data/media/TWRP/.twrps
No se puede montar /data/media/TWRP/.twrps
No se pudo montar '/data' (argumento no válido)
Error al borrar dalvik
Actualizando detalles de la partición...
...hecho
No se puede montar el almacenamiento[/CODE]

No tengo nada que deba guardar en el teléfono, ya que es nuevo.

¿Alguna idea sobre cómo continuar?
Pudiste solucionarlo?

I am on this build, official, from Sep 15 https://download.lineage.microg.org/a52q/lineage-19.1-20220915-microG-a52q.zip . In the Updater app, when I allow it through AFWall, I get "No new updates found." I was hoping to get all the latest changes in Lineage since that September build, those found on this page https://download.lineageos.org/a52q/changes/ . Maybe the Lineage team only produces intermittent releases every so often?

Also, I noticed a bug tonight: the LTE signal strength indicator in the status bar is stuck at the value it had at boot time while travelling through places I know have very different signal strength. This happened again after I rebooted. I checked the signal strength with an app and obviously did not match what the indicator showed. Not sure if this is an issue with my setup, Lineage or the ROM but it would be nice to get this solved.

In any case, thanks for your work on this ROM. There really are not many non-Chinese-made phones with Lineage available these days.

Ah, you're on MicroG, that explains it.
As far as I know LineageOS and Lineage for MicroG aren't made by the same developers, so it's not the same as normal Lineage.
Apart from that I guess they're waiting for LineageOS to move to Android 13 before continuing with new builds.

I've never had that on normal LineageOS, so I guess it's a MicroG-specific bug.

speaking of Android 13, do you plan on upgrading anytime soon?

I am on LOS 19.1 from 30/09 and tried to update to 14/10.

Update seems to work fine in TWRP (3.7). Then, I reboot but it gets stuck on the LOS logo: the blue arc with cercles passing through. It gets stuck there forever...

I have reinstalled the 30/09 version and everything works fine...
Any idea?

    LineageOS is a free, community built, aftermarket firmware distribution of Android 12.1/12L, which is designed to increase performance and reliability over stock Android for your device.
    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
    Code:
    /*
    * Your warranty is now void.
    *
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * 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.
    */

    Supported devices
    All variations of A52 4G and A72 (A525F, A525F/DS, A525M, A525M/DS, A725F, A725F/DS, A725M and A725F/DS) are supported, but only A525F (6/128 variant) is well tested as I have this device.

    Installation instructions

    Recommended
    Follow the guide on the LineageOS website: A52 4G | A72

    Alternative way (TWRP/OrangeFox)
    1. Make sure your device's bootloader is unlocked.
    2. If not done before, flash blank VBMeta with Odin in AP slot.
    3. Make sure to have the latest available version of TWRP/OrangeFox installed.
    4. If wanted, backup all your necessary partitions (super, boot, data, EFS) before flashing this in case something goes wrong.
    5. Download the lineage build for your device from the link below and optionally download your preferred GApps package too.
    6. Flash the LineageOS zip using the "Install" button.
    7. Optionally, flash Gapps right after.
    8. Format data in TWRP/OrangeFox as the very last thing, otherwise you may end up in a bootloop if coming from stock ROM.
    9. Wipe metadata and cache partitions. This only has to be done once when you install LineageOS.
    10. Reboot

    Downloads
    You can find them here on a mirror hosted by me.

    Gapps (choose arm64 and 12.1/12L): MindTheGapps | OpenGapps canary | FlameGapps Canary | NikGapps Canary

    Announcement!
    A52 4G and A72 are now officially supported by LineageOS!

    From now on new builds will be released weekly on LineageOS' website. That means every week there will be new official builds for both devices.
    New builds for A52 4G will currently release on every Friday and for A72 on every Saturday.

    What are the differences between the unofficial and the official versions?
    • The official versions will be updated frequently (every week) with the latest changes from LineageOS.
    • They have OTA-Update support built-in, which means you will be able to easily update to newer versions using the Updater found in Settings->System->Updater.
    • Also, as mentioned by @thatdevsherry and a few other people, hotspot accidentally went broken in the last unofficial build. This has been fixed on the official ones.
    • Macro (A52 and A72) and Tele (A72 only) cameras are now accessible by Gcam, which wasn't working before.
    How do I update to the official version?
    You should be able to just dirty flash the official build over the unofficial ones.

    Apart from that, all device trees and the kernel can be found on github.com/LineageOS and review.lineageos.org. Feel free to contribute!

    Hey people, again thanks for waiting patiently and reporting bugs. Lineage 19.1 is now available with some more bugfixes and improvements!

    Apart from that, SeLinux is now enforcing!

    Also, this build has encryption enabled by default. That means that your data will be encrypted right on boot. If you don't want encryption to be enabled flash something like services disabler before first boot.
    If your phone keeps rebooting after flashing lineageOS 19.1 with encryption enabled make sure to format data in recovery instead of only wiping it.

    Hey people, thanks for waiting patiently and reporting bugs. Lineage 19 is now available with a long list of bugfixes and improvements!

    Before installing, make sure to be on OneUI 4 firmware and have OrangeFox or TWRP 3.6 or newer installed, otherwise you will end up in a bootloop.

    Some notes regarding A72 support
    Since I don't have an A72 here it was kinda hard to blindly support it. But first I wanna thank @madseason.live and Leo on Telegram for testing my builds on their A72's. Even though both of them did good testing, we didn't succeed in getting the fingerprint sensor to work. A72 uses a different sensor and driver than A52 does and without having the device here by myself it's hard to fix that without knowing what the actual issue is. It only works for setting up a fingerprint, but actually unlocking the phone with it doesn't work. Additionally, for somehow screen rotation is flipped by 90° which makes no sense at all since A52 and A72 use the same sensors except for fingerprint and camera. If someone has an idea or wants to contribute, feel free to contact me.
