If you have any suggestion on how can I root my android device. My device is mi 4a.

There are so many powerfull applications available on android devices. Generally the most powerfull application needs root permissions as they require advanced system permissions. However there are so many applications available there using which you can root your android device. Some applications like lucky patcher http://www.techsheap.com/lucky-patcher/ needs root access.
Thanks!
