The Android world It has always been characterized by its flexibility and customization capabilities, but manufacturers, especially Samsung, include several layers of security that can curb your desire to experiment, root, or install custom ROMs. Among these barriers is the famous OEM lock, which, while serving an important purpose, can be unlocked at your own risk and with the proper knowledge. Here, we explain step by step what it is, why it's useful, and how you can activate it. We'll also resolve the common error that the option doesn't appear in the settings.
What is OEM unlocking and why is it included on Samsung phones?
The Android operating system is famous for being open source, which gives users the freedom to personalize and modify their experience. However, manufacturers add barriers to prevent inexperienced users from damaging the system unintentionally, and one of the most relevant is the OEM lock (from the English Original Equipment Manufacturer).
El OEM lock acts as an extra layer of protection over the device's bootloader. It's there specifically to prevent malicious applications, human error, or unauthorized manipulation from compromising the operating system. So, even if you have an Android phone, you won't be able to modify the base software (for example, install another ROM, root, or modify the kernel) without expressly accepting the risk and disabling this OEM lock.
For the more "handy" or those who want 100% control of their phone, this can be frustrating, but Enabling OEM unlocking allows you to gain administrator privileges and access the full potential of your Samsung device. However, be aware of the risks, as any improper handling can render your phone unusable or void the warranty.
Advantages and reasons to activate OEM unlocking
Beyond curiosity, enable OEM unlocking offers very interesting advantages:
- Possibility of unlocking the bootloader: Only with OEM unlocking enabled can the device's bootloader be opened, which is an essential step for thoroughly modifying the system.
- Installing custom ROMs: Completely change the mobile software and install a version of Android free of manufacturer layers or with special functions.
- Root the device: Get superuser access and control everything that happens on your phone.
- Remove bloatware: Delete factory apps and even carrier apps that you don't need and free up resources.
- Modify the kernel, optimize performance and battery: Take your Samsung beyond the limits set by the manufacturer.
- Recovering your phone after a failed updateIf something goes wrong and your phone won't boot, with the bootloader unlocked it's much easier to restore the system or install a clean firmware.
Just activate this feature only if you know what you're doing. And you have a clear purpose: it is not necessary for the average user nor is it recommended if you are just looking for a stable mobile phone for everyday use.
Where is the OEM unlock option on Android and Samsung?

On modern Samsung devices, the path is usually as follows:
- Opens Settings.
- Sign in About of the phone and look for the section Software Information.
- Locate the Build Number and click on it seven times in a row. You may be asked for the unlock PIN.
- You will see a notice that "you are now a developer" and the menu will be enabled Developer Options.
- Go back to the main Settings screen and scroll until you find Developer Options.
- Within that menu, look for OEM unlock and activate the corresponding switch. You will be asked to confirm the security PIN.
- Done! The feature is now active, and you can continue with bootloader unlocking or other advanced operations.

Why isn't the OEM unlock option showing up on my Samsung?

The most common reasons why the OEM unlock option does not appear are:
- The bootloader is now unlockedIf you unlocked the bootloader at some point, the option may disappear (as it's no longer needed). Relocking it may make it reappear, but this process involves completely wiping the phone.
- The device is locked by the operatorSome Samsung models sold by carriers have bootloader access locked to prevent network changes or deep modifications. If this is your case, the OEM unlock may be hidden from the factory and impossible to enable without more complex solutions.
- 7-day waiting periodOn newer models, Samsung introduces a mandatory "wait" period after first activating the phone and linking a Samsung or Google account. The OEM unlock setting won't appear until at least 7 days have passed since the first boot.
- Security protections such as KNOXSome enterprise security features or KNOX options may hide the OEM unlock setting. Disabling them may help, but be aware of the implications for device security.
- Software problems or bootloader corruptionIf the system has been damaged, the advanced options menu may not load correctly. This may require a system restore or technical assistance.
- You have not correctly enabled developer options: It may seem obvious, but if you haven't followed the process of tapping the build number 7 times, you won't see the OEM option.
