One of the core reasons behind Android OS dominance over the smartphone market is that it is an open-source operating system. However, this does not mean that it is something that you can play with or fully customize its performance the way you want.

This is because Android device manufacturers and Google itself uses OEM lock to restrict unneeded user access to certain core areas of the Android OS.

This article explains everything you need to know about how to unlock OEM lock Samsung. Hence, if you are a developer and looking for a reliable Samsung OEM unlock tool, this article will help you.

Part 1: What is OEM Lock in Samsung?

OEM or “Original Equipment Manufacturer” or simply OEM locking is an added security feature which Android device manufacturers use to protect unauthorized access to the device’s Bootloader. This ultimately helps safeguard the Android Operating System running on a device from being interfered in any way. Basically, Samsung OEM lock prevents a non-expert person from accidentally causing damage to their device.

On the other hand, an expert or someone with enough technical knowledge to safely navigate through an Android system’s core areas, might want to troubleshoot an issue, or simply install customizations to their Android device. With OEM lock in Samsung enabled, none of this is possible. Hence, you need to know how to disable Samsung OEM lock.

  • Open your Android device “Settings” menu.
  • Now scroll down until you find the “System” option. Open it.
  • In it, tap on the “About Phone” option and now look for “Software Information” option.
  • In the “Software Information”, there will be your Android device’s “Build Number”.

Method 2: Fixing the hidden Samsung OEM Unlock Missing

Missing OEM Unlock Samsung is a common issue. This means that even after performing the above method on some Samsung device models, it won’t display the “OEM Unlocking (Bootloader Already Unlocked)” toggle On/Off feature.

A common reason behind this may be because your Samsung device uses Android Snapdragon. It can also be because your device haven’t passed the post-activation 7-day lock period which comes pre-set on some new Samsung device models.

Hence, the following are a few tips on how to fix the missing Samsung OEM Unlock feature.

Way 1: By Turning Off the Automatic Date & Time and Auto Update System Features

This method helps if you just recently bought a new Samsung device and couldn’t find the “OEM Unlocking (Bootloader Already Unlocked)” option even after performing Method 1 above.

  • Open the “Settings” menu on your Samsung device.
  • Now look for “General Management” and enter it.
  • In it, tap “Date & Time” and now in it turn off the toggle switch against the “Automatic Date and Time” feature.
  • After doing above, look for the “Set Date” option below in the same list and set the device date to a few days back. By doing this, you are tricking the device system to bypass the 7-day period discussed above.
  • Now return to the “Settings” menu and one after another, tap the following options.
  • “About Phone” > “Software Information” > “Build Information" > Tap it seven times to enable the “Developer Options”.
  • In “Developer Options”, toggle off the “Auto Update System” feature.
