Samsung will let you unlock your Z Fold 3’s bootloader, but at the cost of your cameras
Samsung seems to be trying to discourage users from modifying the software on their new Galaxy Z Fold 3s, giving them a message that unlocking the phone’s bootloader will render the phone’s cameras unusable (via Android Police). This isn’t the first time we’ve seen phone manufacturers pull this sort of trick, but it seems to represent an escalation in Samsung’s fight against its users who want to gain complete control over their phones.
An XDA Forums user confirms that after unlocking the bootloader, the Z Fold 3’s cameras were completely non-functional: facial recognition, loading the camera app, and trying third-party camera apps all failed for them. The user reports that re-locking the bootloader made the cameras work again.
