I unlocked the bootloader of my galaxy a52s 5g (SM-528B)
But the camera doesn't work on any application anymore it's a complete block and when I patch the boot.img with magisk I have a boot loop someone has the same problem or knows how to fix this?

It seems it's a common behavior between newest samsung devices. Look at this video:

Did you get any message like "camera will not function" while in bootloader unlock menu?I bought this phone but if something like this is present then I will cancel,better to buy some other thing.

There is NO problem with the camera when the Galaxy A52S 5G is unlocked !!!

Mine is working pretty fine so I guess the issue is somewhere else !

Did you just unlock bootloader, or manage to root the phone as well?

I tried to root the phone with Magisk and patching the AP file from the official firmware and flashing it with Odin, but it didn't work.
But at every reboot I got the same warning message saying I'm using an unofficial firmware and the such...

So I feel very angry with this device and against Samsung !!!

What you are saying is just false !

This behavior is specific to the Galaxy Flip 3 and Galaxy Fold 3 and it was assumed by Samsung.

Afaik, I haven't seen the same issue with other new devices anywhere, at least anything official and at large scale !!!

Would you mind sending a screenshot as a verification that your bootloader is unlocked with working camera? Just split the screen with camera on the one half and developer options with OEM unlock option open on the other half

This is PRECISELY what i see on my fold 3

if the camera returns AFTER BOOTLOADER RELOCK............

.................It is therefore confirmed that the A52 5G has the same booby trap as the Z fold 3

The Flip 3 does not have this however

Samsung Galaxy A52 5G
I have the A52 5G (SM-A526B) and when I rooted my phone I had no problems with the camera. The only way to verify if OP's problem is intentional by Samsung or something went wrong in his unlocking process is if he (or someone else with the A52s 5G) posts a photo of the bootloader unlock screen. If it is intentional it will clearly say the camera will not function after unlocking

I have the same issue with my SM-A528B. I have unlocked the bootloader (The warning when unlocking the bootloader says nothing about the camera. It is just the regular warning about un-secure software etc.)
I used the latest Magisk to patch the boot image and flashed using Odin. Unfortunately it got stuck in a boot loop and I decided to flash the original boot image back. Now when starting the Samsung camera app, I get the "Camera Failed" error and the app closes. However, when testing other camera apps, some are able to use the front/selfie camera, but the rear camera always gives an error.

Update:
Flashing the BL, AP, CP and CSC did not help.
However locking the bootloader again made the camera work just fine. Thank you samsung for that little feature.

Well no I can't do that as I re-locked my bootloader and that drive me to think there is something wrong with A52S...

Whenever my phone is unlocked (or supposed to be) or locked, the OEM option is always ON and recently I received an OTA update witch means my phone has never really been unlocked even when I got the message my system has been modified !!! ^^
That also explain why I couldn't root my phone with Magisk and the modified AP file.

BTW, if you have a rooted A52S 5G phone could you send me a build.prop file so I'll try to build a TWRP version for this model of phone, or if anyone else could send me this file ?

Thats sad to hear.

To get build.prop you can simply download the whole firmware from a site like samfw.com or with a tool like SamFirm and then extract it.

    Good phone overall, but let down by manufacturer's restrictions. Like the Realme GT.
