The major challenge that is often faced when developing root tools for Samsung devices is the obstacle of Knox, Samsung's enterprise security fail-safe. Any system-level tampering to Samsung devices will trip Knox; immediately voiding your warranty, disabling Samsung Pay, Samsung Health and a number of other Samsung features. However, users can rejoice at this method as it accomplished root without tripping Knox!
A team of developers behind the samFAIL project have developed this tool for the Samsung Galaxy Note 8 (Snapdragon variant), which allows for it to be rooted without disabling any device features permanently. The team behind it have reworked a stock Galaxy Note 8 system image to include root access, and modified the boot image to allow for this. This means that the device can have root access without tripping Knox; however, there is a catch. As it is a system root, SafetyNet will be tripped, meaning you won't have access to Android Pay.
Furthermore, due to a limitation of the boot image modifications you will only be able to charge your phone up to 80%. And don't expect Magisk support for this tool anytime soon, for the same reason as the SafetyNet trip. But, you win some and you lose some, right?
It is also worth noting that while this tweak enables root access, it does not unlock your bootloader; meaning you cannot flash a custom recovery like TWRP, or access fastboot commands. The modified system image is flashed through Samsung's ODIN software. Fortunately, what this also means is that you can easily re-flash a stock factory image if you want to return to a standard configuration. However, considering all that this tool is able to accomplish on on of the most locked-down Android devices out there such a short time after launch is undoubtedly extremely impressive.
