Overview

• One UI 8 removes the “OEM Unlocking” developer option on both beta and stable builds of flagship and foldable Galaxy devices across all regions.
• Firmware code analysis shows the bootloader unlock feature is disabled at the system level, with the ro.boot.other.locked property set to “1” by default.
• Reports indicate that updating previously unlocked models such as the Galaxy S23 Ultra may automatically re-lock the bootloader.
• The change prevents users from installing custom ROMs, rooting devices or making deep software modifications.
• Samsung has offered no explanation for the removal, fueling speculation that it aims to bolster security or satisfy carrier requirements.
