It works good, although i dont know if it supports 2 sim cards
I successfully flashed trough super.img (odin method) the latest pixel experience rom and it works really smooth, also dual SIM works perfectly, fingerprint seems to work at the begin but suddenly crashes, apart this bug all the rest is perfect, even if the rom is still in beta it is good for daily use 😉

GSIs can be installed via TWRP
An unofficial personal build today. Tested and working fine
Both OneUI 4.1 & 3.1
Both Internal Storage & MicroSD Card

Install this TWRP ( I compiled it because Prove N has a lot of work, can't do it now )
Copy your preferred GSI to Internal Storage or External Storage
Go to Install > Install Image > Select your Image > Select System > Swipe to install
Wait for it to finish installing
Then format data. Done
( Tested with A13 GSI )

Did you flash PixelExpirence Android 11 or 12?

12, (5 jun patch)

Just fingerprint issue, for the rest works way better than stock rom, for bluetooth you have to adjust some options upon your headset (I use realme and it works perfect)
Wait, is the bug fixed?
The bug is when the locked/unlocked icon is on top of the charging time or any other text on the lock screen, resulting that the entire text is not readable. this happend at my a32 and i had to go back to android 11 because of it (i've could change the PPI but if the text was finally visible then the keyboard was too small)

Yep that bug still present even if I must admit this is the 1st time I noticed 🤣

I usually don't use the phone while in charge perhaps for this I never noticed before

Anyway it is just an aesthetic bug, unlock works

is it normal for it to be stuck on the OEM screen? i have tried the ChonDoe flasher and fastboot and neither solved it... i have a A32 4G A325M and im trying to flash pixel experience 12.1 (latest by 01/07/22)

Is this TWRP working with the A32 (Because you wrote "Tested with A33 GSI")

Also, does this TWRP flash A/B GSI even tho the phone only has an A slot?

Also one more question: Can i flash the GSI with this TWRP, then install magisk through ODIN's AP slot (boot.img to get root)?

Sorry for late reply
1. I have an a32, so i can confirm it works, for sure, A13 I mean is Android 13, not samsung a13 or a33 phone
2. this phone is Virtual A/B ( this mean this phone can flash A/B gsi )
3. Root is not tested

    I have tested 2 GSI's so far, phh's AOSP and AndyYan's LineageOS 19.1.

    Everything works so far except:
    • MTP file transfer
    • Fingerprint reader
    • File encryption (GSIs don't boot if you dont disable encryption)
    So, if you wanna install one, here's what I did:

    Install Prove N's Unofficial TWRP and follow his guide. DONT INSTALL MAGISK, IT HAS THE IMEI PROBLEM AND ITS NOT TESTED WITH GSIs

    Download your preferred GSI, I recommend lineage-19.1-20220320-UNOFFICIAL-arm64_bvS.img.xz, comes without GAPPS (Use bgS if you want em).
    Extract it and rename the .img file to system.img

    (Optional) Download this vendor.img, I made a treble overlay and added it to the image. The rom should be more stable and power management should be fixed with that. I still have to push the changes to github.

    Download ChonDoe_Flasher.zip, it's a tool to flash dynamic partitions. It checks your storage for system.img and vendor.img.

    Get a microSD card, and copy to the root of it the ChonDoe_Flasher.zip, system.img and vendor.img.

    Boot to TWRP, and install the ChonDoe zip, wait till it finishes flashing.

    Reboot to TWRP again, so it can mount the vendor partition again, go to the terminal and type multidisabler, so we remove encryption.

    Format data, internal storage and reboot, you should be ready to go.

    Settings in PHH Treble Settings
    • Go to Samsung features and check "Enable extended brightness range" and "Enable access to all cameras".
    • Go to Misc features and check "Use alternate way to detect headsets"
    • To get the display working at 90hzs go to "Force FPS" and check the option.
    • On camera check "Expose Aux cameras" and "Force Enable Camera2API HAL3" (In theory you should get better photos with that but I didn't go outside today lol)
    For the lack of MTP file transfer, I'm using ADB instead of MTP with this tool for uploading and getting files from internal storage: Python ADB File Explorer. Suprisingly it's faster than MTP for some reason...

    I know MTP can be fixed changing the kernel driver, I have compiled the kernel from @Prove N. , he had some USB fixes, but I don't know how to pack it for Samsung, It could be nice to have it for GSIs. If anyone wants to help me with these small issues it would be awesome.

    Report bugs, workarounds and fixes here in this thread, let's try to make this phone usable!

    Ok, I'll try not to mess it all up this time...

    Here is the link to download: {Mod edit: Link removed. ufile.io is not accepted as file host on XDA}. That is super.img I've created using my script, it is packed into a tar archive and zipped to reduce the size for file sharing. It is specifically for SM-A325F, based on the NPB (Nepal/Butan) version of the firmware and contains LiR v3.16. After unzipping it is ready to be flashed using Odin into the AP slot over the stock NPB firmware. That means, you have to download and flash it first, then flash the super.img. After each flashing go straight into the Recovery mode and do factory reset, only then boot the system.

    But that's not all, additionally you have to extract and flash optics.img from your regional firmware. Here is how to do it. Changing optics.img to your regional one is not compulsory but with the Nepalese/Butanese one you'll only have a few major cellular providers working. You can do it at any time after flashing the system, it does not require factory reset.

    I have chosen the NPB stock firmware as the basis because after analyzing contents of other regional firmware I've found that it is probably the most non-bloated and privacy-respecting of all (the worst were Russian and European).

    all good please create one ui firmware
    Do you really need it? First, OneUI is not to be trusted as it's proprietary and not fully open-source, second, the only GSI version of it I can find (repacked by erfanoabdi) is very old (2019).

    Would love this tbh.
    gapps would be preferred
    I tried to download it, but it took 1 hour and chrome said "network error", so i only can get the lineage os gsi.
    Maybe it is because they have bad servers

    ok, can i install a gsi which is for a/b slot (e.g Pixelexperience 12)
    yea it works. although install v414 v415 causes the device to immediately reboot on samsung logo.
