Risks and Benefits of Unlocking Bootloader on Tab S8

Unlocking the bootloader in any android device is the first step to a custom ROM experience. Users who are not satisfied with the OEM flavour of android or the users who just want to try something new can use custom ROMs to change and customise their experience. These ROMs are maintained by regular developers who spend their time and energy crafting and maintaining them for years to come. Some of the popular custom ROMs include Pixel Experience and LineageOS.

But there’s always another side to a coin as well. Unlocking the bootloader voids the warranty of a device. Thus making future repairs very difficult and expensive. In the case of Samsung, when the bootloader is unlocked, the Knox counter is tripped. Therefore apps like Samsung Pay and Secure Folder will not work. There will also be issues with banking apps, but their support depends on the ROM you installed.
