Android makers remove bootloader unlock: Will Xiaomi follow

Samsung has officially discontinued bootloader unlocking on all OneUI 8 builds, a significant move that directly impacts device customization and developer access. This policy now applies across the board—stable and beta firmware, from flagship Galaxy S25 models to the Z Fold series. The change is likely to prompt broader discussion among Android manufacturers, especially as companies like Xiaomi continue to support (albeit cautiously) user modifications.

Comprehensive Restriction Across Product Line

The new restriction on bootloader unlocking applies to Samsung’s entire device lineup running OneUI 8. According to internal sources, the updated firmware actively blocks all unlocking attempts, marking a clear departure from previous Android versions.

Additionally, current devices with unlocked bootloaders will be automatically relocked upon upgrading to OneUI 8. This affects key models, including the Galaxy S23 Ultra and S22 Ultra, compelling users to choose between maintaining customization capabilities and receiving the latest system updates.

Broader Industry Impact

Samsung’s decision reflects a larger trend within the mobile industry: increasing emphasis on security and tighter control over device software. These changes align Samsung with evolving enterprise security requirements and stricter digital rights management policies now seen across many manufacturers.

Xiaomi’s Bootloader Policy: A Contrasting Approach

While Samsung tightens restrictions, Xiaomi maintains a more flexible—albeit increasingly limited—bootloader policy. In China, local regulations prevent consumers from unlocking devices. However, global Xiaomi users can still unlock bootloaders after completing an application process, which typically requires up to two months from start to finish.

Looking Ahead: Android’s Customization Landscape

Samsung’s new policy underscores a shift in the Android ecosystem, as manufacturers move toward more controlled, secure environments. The balance between user autonomy and system security continues to evolve, and it remains to be seen how competitors will respond.
