Question A52S 5G (SM-A528B) Unlock bootloader camera failed

[Pinokaille]

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:

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

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 !

SM-A528B model ?​

 

[Jumpkid]

Yes !

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

i had the same issue after unlocking the BL, had to relock it again to get the camera to work.

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

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.

i can confirm that unlocking BL on SM-A528B makes camera unusable. black screen same as OP stated.

Samsung fixed this camera issue on the Galaxy Z Fold 3, we hope it will do the same with the SM-A528B.

SM-A528B bootloader is still not unlocked but there is a workaround when rooting it with Magiskv24.3.

You may have to repatch the AP file and flash it again, and then enable Zygist option in Magisk 24.3, install LSPosed-zygist module and SafetyNet Fix 2.2.1. reboot.

On, first try the camera won't work, so you have to force close the camera app in Settings, Applications.
Camera should work on next try.
You have to redo this same operation after every reboot... ^^

I did this step by step and everything was fine with root and camera working 100%.

Is there any fix for that? I unlocked the bootloader of my Galaxy A52s (SM-A528B/DS) and I get the damn error.
I just don't want to continue and root the phone unless I'm 100% sure that the camera will work...

Dammit Samsung!

 

[jmbnus]

This is explained in post #22 just above !!! ^^

But that involves triggering knox. I want to avoid triggering knox (be it with root or flashing a patched AP) unless I'm 100% sure that camera will work.

Considering that just with the bootloader unlocked but nothing flashed the camera doesn't work.... I can't be 100% sure.

Thanks for trying to help, tho.

 

[jmbnus]

You can't root this phone without triggering Knox !!!

Once again read post #22 to who I answered and read back the answer at post #23 about the result with the camera...

Once again: But that involves triggering knox. I want to avoid triggering knox

It's good that you spend your time trying to help people make the most out of their phones, but you try so hard to convince people on using your how-to's that you often ignore what compromises they are willing to make / not make.

 

[jmbnus]

Listen, you asked to know how to root your phone with you camera working and I gave you the answer which is already an "exploit". If there was a way to avoid triggering Knox you can imagine I would use myself it asap as any other users too but there is none !!!
Want to root your phone ? Then you have to make this compromise, if not, then don"t root your phone Period

Read again, but this time read right please:

Nowhere in this thread I asked how to root my phone....

Get out and do something else besides trying to get everyone to follow your xda tutorials. Most importantly read correctly before going off on someone for not following your suggestions.
You might think that I'm nobody to tell you something like that, but trust me... I'm doing you a favour, it will help you to not be perceived as a maniac easy to trigger whenever someone rejects his suggestions.
