It is important to have a rooted handset because who knows when you will need access to its internal system. On a rooted OS you can install complex apps that requires root access in order to work properly (such as CWM recovery and some backup and restore tools), you can remove in-built programs in order to improve the speeds, optimize and customize the system and so on. The best part is that once the root access is granted you can start updating your Galaxy S3 with the latest custom ROMs, which are being perfect for those who want to try something different than the classic or default Jelly Bean experience.
In a few words, if you want to properly use your smartphone, gaining root access is a must have. Actually, this will be the first step to make if you want to power up the Galaxy S3 performances, so why not to try the same? The root procedure can be easily performed, the present step by step guide being all that you need. You have all the aspects needed explained and detailed below, so let’s get started.

This aspect can’t be avoided, so if you are not sure that you can safely complete this guide, maybe it will be better to stop going any further.
Also, a backup is strongly recommended even though it is unlikely to lose your personal info while trying to root the Galaxy S3 by using this step by step guide.
