KingRoot
This application, when installed, provides a means of rooting the phone locally (no need a PC). While this is a simpler method compared to SuperSU, it does have a lower rate of success. Also, do note that superuser management app KingUser will be installed as a result. Users might want to replace it with SuperSU instead.
iRoot
Similar to KingRoot. Some users report more success with iRoot than KingRoot.
