Samsung’s upcoming One UI 8 update is locking down bootloader access on Galaxy devices worldwide, ending an era of flexibility for enthusiasts and developers.
One UI 8 removes OEM Unlock toggle globally
In the One UI 8 beta builds, Samsung has quietly deleted the OEM Unlocking switch from Developer Options even on international models that previously allowed unlocking. A key code change (androidboot.other.locked=1) confirms this, ensuring the bootloader toggle won’t appear on devices like the Galaxy S25 series, Z Fold 7, and Z Flip 7.
Tommy Mysk revealed that applications, including TikTok, Facebook, Twitter, LinkedIn, and Bing, leak data from iPhones through notifications.
What One UI 8 means for power users
Without access to OEM Unlock, advanced users can no longer tamper with the firmware. That means no custom ROMs, no root, no flashed kernels. Even phones that were previously unlocked may be relocked after updating to it.
Why Samsung may be closing the unlock door
Phone makers globally are tightening control. Samsung’s move may boost security, simplify official updates, or align with carrier demands. OEMs like Xiaomi have already banned unlocking in regions like China. Samsung’s One UI 8 has yet to issue an official statement on this shift.
How to respond if you rely on unlocking
Still on One UI 7 or lower? Consider staying until you decide if customization is worth losing. Once your device updates or a new Galaxy launches with One UI 8 the bootloader unlock feature will be gone for good.
What this means for Samsung’s ecosystem
The vast majority of consumers won’t notice the changes in One UI 8. But modders, ROM developers, and tinkerers are facing a turning point. Samsung now controls both software and firmware access, making Galaxy devices less adaptable and less appealable to power users.
Galaxy smartphones just got a lot less open.
