So I got my A52 and started installing the ROM today. Thanks for your support so far!

In TWRP, after flashing multidisabler, I flashed Lineage (originally tried the microg build, then tried the latest nightly) however the system will not boot. It goes back into recovery if I attempt to boot into system. I used the TWRP linked in your original post @Simon1511 .

Attempting to wipe Dalvik/ART Cache or Data in TWRP shows the following errors:

Unable to mount /data/media/TWRP/.twrps
Unable to mount /data/media/TWRP/.twrps
Failed to mount '/data' (Invalid argument)
Failed to wipe dalvik
Updating partition details...
...done
Unable to mount storage

I don't have anything I need to save on the phone as it's brand new.

Any ideas on how to proceed further?

Hi guys!!! I am writing software that raises an access point with the given parameters !!! But unfortunately, due to firmware limitations, I can’t do it on my a72q device. What do I need to change in the firmware?? Maybe something to change in the kernel ??

I'm not an expert here but it seems you need to give your application the permissions to change system settings.

data roaming didn't work on mine
[Samsung Galaxy A52 4G] thefallenghost:
I can happily report that data roaming DOES work on mine. A525M/DS

Maybe try playing with APN settings, data roaming switch, reboot, etc.
[Samsung Galaxy A52 4G] thefallenghost:
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
[Samsung Galaxy A52 4G] thefallenghost:
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.
[Samsung Galaxy A52 4G] Simon1511:
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.

Pudiste solucionarlo?
[Samsung Galaxy A52 4G] thefallenghost:
As @Simon1511 suggested: Please try to format data instead of wiping it, and then after that wipe metadata. That worked for me.
[Samsung Galaxy A52 4G] thefallenghost:
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.
[Samsung Galaxy A52 4G] Simon1511:
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.
[Samsung Galaxy A52 4G] Simon1511:

Trying it rn!
[Samsung Galaxy A52 4G] xinouch:
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?
[Samsung Galaxy A52 4G] Simon1511:
Thanks for reporting, I will check if it's an issue with that specific build or if dirty flashing is the issue here.
[Samsung Galaxy A52 4G] thefallenghost:
I will be interested to know as well as microG has produced a build with that version and it is now available via OTA update. I am holding off on updating via OTA until the mystery is solved.

I think my issue with the cell signal indicator being stuck is related to what some API functions return for the cell signal. Most cell-signal monitoring apps, including the system one (in SIM Status) report the same values forever. Some apps, using alternate cell-signal APIs, do report the correct values however. Hopefully this latest build will solve my problem.

Oh and another question: is there any way to increase/control the vibration strength? For me it is pretty weak. I can imagine in winter with my thighs numb I won't feel any vibrations... I tried every method I could find but to no avail. I don't see any build property for vibration strength either. Don't know if the stock ROM has this ability.
[Samsung Galaxy A52 4G] Simon1511:
I'll check with both the latest LineageOS and MicroG builds.

Yes, stock ROM has a setting for that if I'm not wrong, I'll see if I can make it work on Lineage too.
[Samsung Galaxy A52 4G] Simon1511:
Both the latest LineageOS and LineageOS for MicroG builds work just fine here. I also had no issues with the signal strength indicator.
[Samsung Galaxy A52 4G] thefallenghost:
Can I do an OTA update if I am using TWRP? When I touch Install on the update it says "This feature requires a compatible Recovery or updates will need to be installed manually.".
[Samsung Galaxy A52 4G] xinouch:
I must be doing something wrong here...

I just need to flash the LOS zip and reboot, right? No need to reflash Gapps nor Magisk, or wiping any caches?
[Samsung Galaxy A52 4G] xinouch:
With TWRP 3.7 it "worked" for me. In the worst case, the downloaded zip file is stored in `/data/lineageos_updates`, so you can manually flash it from TWRP
[Samsung Galaxy A52 4G] thefallenghost:
I think I read on a website that you need to wipe the Dalvik cache after flashing the LOS update zip.
[Samsung Galaxy A52 4G] thefallenghost:
I updated from https://download.lineage.microg.org/a52q/lineage-19.1-20220915-microG-a52q.zip to https://download.lineage.microg.org/a52q/lineage-19.1-20221016-microG-a52q.zip by downloading it in Updater app and manually flashing from `/data/lineageos_updates`. I also pressed the "Wipe Cache & Dalvik" afterwards. My A52 booted successfully into Lineage with no issues afterwards. Just remember with Magisk 25.2 all modules get disabled after doing ROM updates.

I am still having the same issue with my cell signal bar however. Very odd and annoying. The SIM status just shows the same values forever (they fluctuate a tiny bit after boot though). Hopefully I can find a solution for this. @Simon1511 do you know how I can investigate this? I am a developer but don't have experience in ROM development. Not sure if the relevant code is in LineageOS or proprietary by Samsung.
[Samsung Galaxy A52 4G] rhystic:
Hello, there is one thing about animation/effect in UI that I noticed. It is best visible on dark theme. Go to settings and click on any entry. The feedback animation which makes a button light up briefly is pixelated, grainy. It isn't smooth as on stock Rom. The same can be said about buttons in Quick Access list. It happens on light theme as well, but as the contrast is much lesser it's barely visible.
[Samsung Galaxy A52 4G] Simon1511:
The code is most likely somewhere in LineageOS's sources, I wouldn't know where to search though. Can you possibly check if the same thing happens on normal LineageOS?

Yeah I noticed it too, it's happening on some of my other devices too. I'm not sure why it happens though.
[Samsung Galaxy A52 4G] thefallenghost:
Well, since I don't really have experience restoring backups with ROMs I am wary of reinstalling everything since it took a while to setup everything right on the MicroG build.

Not sure what to do. I will try to look at the LineageOS code. I was thinking maybe I can hook onto the TelephonyManager class and call the cell API functions that do work with XPrivacyLua but I don't know which app is responsible for displaying the signal status icon. Probably something under user 1000. Not sure if that will work since LSPosed doesn't like hooking onto system apps. I could also write an app that displays an icon as a notification but that would require permanent location permission and the icon would not be visible on the lockscreen...
[Samsung Galaxy A52 4G] polaco07:
In my experience, updating let's say week by week, all I did was wipe the two dalvik caches and that's it only once I had stopped updating it for about three months, the new one did not start and I had to wipe data this with other models, not the A52 I'm a bit complicated I haven't even unlocked the boot yet

With the update from this week (21/10), I just let the LineageOS updater do all the job and it worked fine.

It downloaded the update and reboot the phone and automatically installed it. Gapps and Magisk are working fine too (though I have no modules installed).
[Samsung Galaxy A52 4G] Peter_Petersen:
Hello Simon1511, I still have the problem that the display jumps to minimum brightness in direct sunlight. In contrast, at minimum brightness (for example, when i use the phone as navigation sytem in the dark), the display jumps to maximum brightness. Both happen randomly. I have had this problem since I started using this ROM in July.

Another thing is that when I'm on Wi-Fi for hours, the mobile data connection no longer activates, so I have to restart the smartphone.

Both bugs also occur on my daughter's smartphone.

Does anyone have the same problems or a solution?

[Samsung Galaxy A52 4G] Flyos:
Hi. I have TWRP installed, because I have rooted stock ROM. If I understand correctly, if I want to benefit from OTA updates from LineageOS, it's better to install Lineage Recovery. Any advice on how to replace TWRP by Lineage Recovery? Or is that not needed to benefit from OTA?

EDIT: Precision, I haven't installed LineageOS yet, about to do it in the coming weeks, but want to sort this issue about bootloader first.
[Samsung Galaxy A52 4G] Simon1511:
As the guide on the lineage website says, you can just download the latest recovery image from their website, rename it to recovery.img, convert it to a TAR and flash it in Odin.

If you decide to install TWRP first you can still move the lineage recovery image to your phone, hit "Install", then "Install image", select the lineage recovery image and select "recovery".
[Samsung Galaxy A52 4G] Flyos:
My problem is that I already have TWRP installed, so I'm unsure whether I can follow those steps on the guide.

If I understand what you stated, I can install Lineage Recovery through TWRP as you describe and all will be well for the rest of the instructions online?

Thanks for both the help and the build!

Hi,

i have problems to get google assistant to work. (Listening to "hey google")

Google and Google Assistant are installed.

Google Assistant Hey Google is grayed out, is this a known bug ?

I installed MindTheGapps with the lineage-19.1-20221209.

In other threads, i read the following:

[B]Google app should be a System app so Access with Voice match can work[/B]
If you are facing the problem you must be on a custom ROM with Pico Gapps installed. If yes, the Pico GApps package doesn’t include Google app so it will not be installed as a System app.
If your smartphone is old and came with the Older Android versions then the chances are that Google app didn’t came as System app by default.

And in the MindTheGapps Google App is not included, may this is the problem ..

Is there a chance to migrate the google app as a system app, without reinstalling.
[Samsung Galaxy A52 4G] Rampler:
Hi,

maybe a stupid question. Does the A52 have a notification LED ?

If i search for LED in the settings, i find some stuff. But i see no notification ...

Searching in the settings finds some LED stuff, but if i search each setting item, i find nothing.
[Samsung Galaxy A52 4G] Simon1511:
You can either try different Gapps or add the Google App apk to /system using a custom recovery.

I'll try to check on my own phone in the next few days and see what the issue is.

Nope, it doesn't.
[Samsung Galaxy A52 4G] xinouch:
I think there is someone doing a Pixel Experience build for the A52. You can find it on the telegram linked in the first post of this thread.

From what I understand, it is based on this build, with preinstalled GApps. It may solve your problem?

Thanks for the information, but i am a fan of lineageos. I do have hope that Simon1511will find a solution.

I created a guide to fix such issues earlier: https://telegra.ph/Passing-safetynet-with-Magisk-v24-and-newer-03-03

The guide will definitely fix the CTS profile matched issue. Not sure if it fixes the LOCK_BOOTLOADER issue either, but maybe adding that app to Magisk's DenyList helps.
[Samsung Galaxy A52 4G] Rampler:
At the moment I don't have Magisk installed (only Lineageos + Lineageos Recovery + MindTheGapps). So I'm wondering about the failed reporting of the cts profile. I thought without Magisk, without root, everything is fine.. You recommend using Magisk even if I don't want root privileges just to solve the CTS problem?

Hi, first of all, thanks for your help. (y)

OK, now i have installed magisk with your guide.

I have installed the Lineageos via the guide on the lineageos website, with success. There is no topic with vbmeta installation on their webpages.

[Samsung Galaxy A52 4G] Rampler:
OK, i will answer myself. (found somewhere on the www)

After flash is complete the phone will automatically reboot and enter the stock recovery mode. It will prompt you to reset the device because the VBMeta signature has been changed.

Therefore vbmeta should be installed before installing the custom rom ...
