Android devices don’t come rooted for a reason. In fact, some device manufacturers go out of their way to prevent you from rooting. Here’s why:
Security: Rooting breaks apps out of Android’s normal security sandbox. Apps could abuse root privileges you’ve granted and snoop on other apps, something which isn’t normally possible. In fact, Google prevents you from using Android Pay on rooted devices for this reason.
Warranty: Some manufacturers assert that rooting voids your device’s warranty. However, rooting will not actually damage your hardware. In many cases, you can “unroot” your device and manufacturers won’t be able to tell if it’s been rooted.
Bricking: As usual, you do this at your own risk. Rooting should generally be a very safe process, but you’re on your own here. If you mess something up, you can’t just expect free warranty service to fix it. If you’re worried, do a bit of research first and see if other people report success rooting your device with the tool you’re planning on using.
<strong>You only need to root your phone if you want to run a specific app that requires root access</strong>. If you don’t plan on actually doing anything with that root access, don’t bother. You can always root it later if you need to.
