Samsung kills the cameras on the Galaxy Z Fold 3 if you unlock the bootloader


Knox is the security suite on Samsung devices, and any modifications to the device will trip it, void your warranty, and disable Samsung Pay permanently. Now, losing all the Knox-related security features is one thing, but having to deal with a broken camera is a trade-off that many will be unwilling to make. But that’s exactly what you’ll have to deal with if you wish to unlock the bootloader on the Galaxy Z Fold 3.

According to XDA Senior Members 白い熊 and ianmacd, the final confirmation screen during the bootloader unlock process on the Galaxy Z Fold 3 mentions that the operation will cause the camera to be disabled. Upon booting up with an unlocked bootloader, the stock camera app indeed fails to operate, and all camera-related functions cease to function, meaning that you can’t use facial recognition either. Anything that uses any of the cameras will time out after a while and give errors or just remain dark, including third-party camera apps.

This is the very first time I have heard that a manufacturer just outright kills the camera when the bootloader is unlocked. I know Sony degrades the camera quality if it's unlocked but not like this. I can expect future Samsung phones like the S and A series do the same.
