A bricked device is of no use as you can never switch on it. So, if your Smartphone is under warranty period, it could be a big decision to root your device as rooting has even lead to a brick of your device.
However, rooting has one major disadvantage that it voids the warranty period of your android device. Also, the mobile performance and the efficiency get an increase so you get a wonderful experience as compared to your un-rooted smartphone. However, rooting has become very popular in the last few years as you can download custom ROMs and can download and access thousands of beneficial and unique apps after rooting. Rooting is basically a process which allows you to get Root access for your android device.
