We’re starting to see more and more people getting their hands on the new Samsung Galaxy Note 8, so for those of you looking for some help in rooting your device, XDA Recognized Developer dr.ketan has made a simple step-by-step guide for you. This guide will walk you through how to gain root access to the device using SuperSU. The developer also promises to provide an EFS backup tool so you can save the important data in this partition.
Once your device is rooted, you open up the device to some interesting modifications such as flashing the popular audio mod called Viper4Android. Of course, there are already a ton of things you can do without root on Samsung devices such as blocking ads and disabling bloatware, but having root access is an added benefit nonetheless.
