Understanding Bootloader Unlock on Samsung

If you have seen a bootloader Unlock/OEM Unlock for any other device other than Samsung, you would be able to see a bunch of fastboot commands being given. This is true for almost all Android devices except for Samsung. In Samsung devices, the OEM has built-in this particular feature right into the device that all you are required to do to unlock the device is simply enable an option called ‘OEM Unlock’.

Once you unlock the bootloader, you can proceed to install TWRP Recovery on your Samsung device and even root your device with Magisk. Unlocking the bootloader is sort of an agreement with your manufacturer that you take full responsibility for what happens to your Android device. It also unlocks a wide range of options for a power user such as installing a custom ROM or flashing custom Kernel or take a full nandroid backup of your device etc.

But always remember that with great power comes great responsibility. Make a full backup of your device always before doing any power-user stuff so that you can always restore and get back your data and settings.
