Unlocking a Samsung phone allows you to use it with any carrier and install custom ROMs. However, some Samsung users have reported that the OEM Unlock option is missing from their phone’s Developer Options. This article explores the causes of this issue and provides solutions to fix it.

What is OEM Unlock?

The OEM Unlock option is a security feature in Android phones that allows users to unlock their bootloader, which is required to install custom ROMs or recoveries. By default, the OEM Unlock option is hidden in Developer Options to prevent inexperienced users from tampering with their phone’s software.

Causes of Samsung OEM Unlock Missing

There are several reasons why the OEM Unlock option may be missing from your Samsung phone’s Developer Options:

  • Your phone’s software version may not support OEM Unlock.
  • Your phone may be carrier-locked, which means the OEM Unlock option is disabled.
  • Your phone’s bootloader may be already unlocked.
  • Your phone’s firmware may be corrupted or modified.
  • There may be a bug or glitch in your phone’s software.

Solutions for Samsung OEM Unlock Missing

If the OEM Unlock option is missing from your Samsung phone’s Developer Options, here are some possible solutions:

1. Check your phone’s software version

Not all Samsung phones support OEM Unlock, especially those with older software versions. To check if your phone is compatible with OEM Unlock, go to Settings > About Phone > Software Information and look for the “Build Number” or “Software Version”. If your phone’s software version is older than Android 5.0 or the latest available update, it may not support OEM Unlock.

2. Check if your phone is carrier-locked

If your Samsung phone is locked to a specific carrier, the OEM Unlock option may be disabled by default to prevent unauthorized unlocking. To check if your phone is carrier-locked, insert a SIM card from a different carrier and see if it prompts you for an unlock code. If it does, contact your carrier to request an unlock code or use a third-party unlocking service.

3. Check if your phone’s bootloader is already unlocked

If you have previously unlocked your phone’s bootloader using a third-party tool, the OEM Unlock option may not be available anymore. To check if your phone’s bootloader is already unlocked, boot into fastboot mode by pressing and holding the Power + Volume Down buttons. If you see “UNLOCKED” or “OEM UNLOCK” in the top left corner, your bootloader is already unlocked.

4. Flash stock firmware on your phone

If your phone’s firmware is corrupted or modified, it may cause the OEM Unlock option to disappear. To fix this, you can flash the stock firmware on your phone using Odin or Smart Switch. Make sure to download the correct firmware for your phone model and region, and follow the instructions carefully. Note that flashing firmware will erase all data on your phone, so make a backup before proceeding.

5. Try a factory reset

If none of the above solutions work, you can try doing a factory reset on your phone. This will erase all data and settings on your phone and restore it to its original state. To do a factory reset, go to Settings > General Management > Reset > Factory data reset. Note that this will not unlock your phone’s bootloader if it is carrier-locked or not supported.

Tips for Samsung OEM Unlock

If you have successfully enabled OEM Unlock on your Samsung phone, here are some tips to keep in mind:

  • Make sure to backup your data before unlocking your bootloader, as it will erase all data on your phone.
  • Use reputable custom ROMs and recoveries to avoid bricking your phone.
  • Do not install firmware or software that is not intended for your phone model or region.
  • Be aware that unlocking your bootloader may void your phone’s warranty and may not be reversible.


The OEM Unlock option is an important feature for Samsung users who want to customize their phone’s software.
