Answer: First of all, it is necessary to be clear that not all brands of mobile phones are good at obtaining root access, it depends on the official attitude, domestic mobile phone manufacturers are better rooted with OnePlus, Xiaomi.

For brands that can obtain root access, there are two types of obtaining root access, one is to use root software, and the other is to use card swiping package.

The first method is not recommended, whether it is kingroot or other flashing software, it is difficult to uninstall cleanly, and the root permission is incomplete. But if you don't care about this, you can use software such as kingroot to root with one click.
