Samsung is reportedly removing the ability to unlock the bootloader on Galaxy devices with its One UI 8 update in regions where this feature was previously available, as noted on July 28, 2025.
In the US, Galaxy users have never really had the option to unlock their device’s bootloader. In contrast, other countries allowed this feature. The One UI 8 update appears to end this practice.
Evidence from One UI 8 shows that bootloader unlocking is no longer supported. Specifically, the “OEM Unlocking” setting in developer options is missing. This has been observed in beta versions on the Galaxy S25 Ultra and on new devices like the Galaxy Z Flip 7 and Fold 7, which come with One UI 8 pre-installed. Firmware code and user reports confirm this change.
For most Samsung users, this won’t matter much. The majority don’t explore advanced settings or understand what a bootloader is. However, for tech enthusiasts who enjoy customizing their devices with custom ROMs or tweaking their software, this is disappointing news, as it limits their ability to modify their devices.
This change enhances system integrity by preventing unauthorized modifications, ensuring devices remain secure for sensitive apps like banking. A locked bootloader reduces the risk of vulnerabilities that could compromise user data or allow malicious apps to bypass security measures, fostering trust in financial transactions. However, it limits customization options for enthusiasts.
While Samsung will still have a way to unlock bootloaders for their own purposes, regular users will no longer have access. It’s unclear if this change will affect older models like the Galaxy S23 when they update to One UI 8, but it’s a possibility.
Other Android brands, like Xiaomi in China, have also restricted bootloader unlocking in recent years, leading some users to find complex workarounds to continue customizing their devices.
