- Samsung globally removes 'OEM Unlocking' in One UI 8, limiting advanced customization.
- The restriction particularly affects those who install custom ROMs and modify the system.
- Most users won't notice any changes, but it will impact the developer and enthusiast community.
- The measure, already implemented in the US, will be gradually extended to all new Galaxy models.
Samsung has taken a significant step in the evolution of its operating system for Galaxy devices. The arrival of One UI 8 brings with it a major change that directly affects advanced device customization: the global removal of the 'OEM Unlocking' option from developer settings. This decision, while not immediately noticeable to the average user, marks a turning point for those who were accustomed to modifying the software on their Samsung mobile phones.

For years, OEM unlocking allowed Galaxy owners to access their devices' bootloader . This step was essential for installing custom ROMs, changing the operating system , or making advanced firmware adjustments. With the company's new strategy, this option is being closed in most territories, unifying the restrictive policy already in place in the United States.
A change detected in the beta version of One UI 8
The removal of this option has been confirmed following discoveries in the internal code and the beta version of One UI 8. Users and developers have noted that the ability to enable OEM unlocking has disappeared on newer models such as the Galaxy Z Fold 7, Galaxy Z Flip 7, and Galaxy S25 Ultra, all of which come with Android 16 and One UI 8 pre-installed or in beta. For those who want to better understand how to manage the bootloader on their devices, you can consult this Bootloader Guide.
The discovery of a specific line in the firmware , identified by users of forums such as XDA Developers, reveals the instruction "androidboot.other.locked=1", which hides the OEM unlocking function and prevents any deep modification of the device from boot time.
Users who have updated to the One UI 8 beta in various regions around the world, including East Africa and Europe, have already encountered the absence of the OEM unlock toggle in the developer menu. This change confirms Samsung's intention to make this feature a global option , and not simply a software bug.
Who is affected?
The vast majority of Galaxy mobile users won't notice the disappearance of this feature . For the average user who uses their phone as it comes from the factory, accessing the bootloader or installing custom ROMs is unfamiliar territory, so this change will go unnoticed. If you want to avoid problems when trying to revert to a previous version of Android, this guide has all the information you need.
However, modding enthusiasts, developers, and advanced users are the ones who will truly lose options. Locking the bootloader prevents tasks such as rooting the system, installing custom kernels, or keeping older devices updated with third-party software—tasks that gave many phones a second life .

The measure adds to a growing trend within the Android ecosystem: other manufacturers such as Xiaomi have also tightened unlocking policies in markets such as China, closing the door to deep customization through official methods.
Why has Samsung taken this step?
Several sources suggest that Samsung's decision stems from both security concerns and a new vision focused on controlling the user experience. By preventing the installation of modified operating systems, the company can ensure greater system integrity, minimize errors, and reduce exposure to vulnerabilities that can arise from unofficial modifications.

However, the move has not been without controversy among the brand's more technically minded fans, as it severely limits the customization freedom that has characterized the Android world for years. While the removal of the OEM unlocking option doesn't affect the phone's everyday functionality, it does bring an end to an era of experimentation and extended lifespans for many devices.
Impact on the future of customization at Samsung
The available information indicates that the bootloader lock will primarily apply to models that officially receive One UI 8. Older devices, such as the Galaxy S21 or earlier generations, may retain this feature if they don't update to the new software version.

The measure doesn't prevent Samsung from unlocking its devices for very specific cases (such as research or advanced support), but the quick and direct route users previously used is no longer available. Therefore, those wishing to revive their older Galaxy devices with custom ROMs will have to resort to unofficial methods, provided the hardware and software allow it.
The gradual disappearance of the OEM unlocking option indicates that, at least for now, the brand prefers to prioritize system stability and security over opening up and giving the user full access to the device's internal layers.
With One UI 8, Samsung is not only updating its interface and features, but also setting new boundaries for customization of its Galaxy phones. For most, it will make little difference, but for an active minority of enthusiasts and developers, the arrival of the new system closes many doors and projects.
