Samsung appears to be disabling bootloader unlocking in One UI 8 on more devices than before. Previously, only US models lacked the OEM Unlock toggle, but the restriction now seems to be spreading ...

A toggle that would let Samsung owners install custom software has disappeared on phones shipping with the new OS, and One UI 8 beta builds for the Galaxy S25.

SammyGuru gathered reports and evidence from One UI 8 that shows that, like in the US, bootloader unlock is no longer available. Specifically, the “OEM Unlocking” developer option has vanished.

Previously, she was a writer and editor at MUO. Samsung’s One UI 8 update seems to prevent users from unlocking their device’s bootloader to load custom ROMs, as spotted earlier by SammyGuru.
