Samsung One UI 8 Removes OEM Unlocking, Blocking Custom ROM Installation on Galaxy Devices

 

 

 

Samsung’s One UI 8 update, built on Android 16, has introduced several new features for devices like the Galaxy Z Fold 7, Galaxy Z Flip 7, and Galaxy S25 Ultra, but it also comes with a major change that has caught the attention of developers and Android enthusiasts. According to reports from SammyGuru and developers on the XDA forum, the OEM Unlocking toggle has been completely removed from the developer settings in the stable One UI 8 build. This feature previously allowed users to unlock the bootloader, enabling them to install custom ROMs and gain advanced access for deeper customization.

Experts believe this is not a temporary glitch but a deliberate change, as evidence suggests the toggle has been removed from the firmware code itself. This decision could significantly affect developers, modders, and tech enthusiasts who rely on bootloader unlocking for flashing custom ROMs, rooting, and installing modified firmware for enhanced performance and functionality.

Samsung has historically restricted bootloader access on certain US models, but this is the first time such a move appears to affect global variants as well. While this enhances device security and may reduce risks linked to unauthorized modifications, it also limits Android customization — one of the core appeals for power users.

This change has sparked debates within the Android community about user freedom, customization rights, and the balance between security and flexibility. As Samsung continues pushing One UI as a more secure and user-friendly platform, the removal of OEM Unlocking may signal a shift toward stricter controls on device modifications.
