Rooting the Samsung Galaxy A7 smartphones means becoming the root user by getting access to the root user account that is always there on the Android operating system, it is just locked up by default. There is a lot to learn with customizing a smartphone like the A7 that runs Android and it is not all directly to do with rooting as such either. Most people who enjoy customizing Android do it for two reasons. In no particular order, the reasons are to change the stock ROM for a custom ROM or new kernel and to start running apps that need you to be a root user before they work. Rooting Android does not require you to unlock the bootloader and install a custom recovery–those things are what is needed for installing new ROMs and kernels. Rooting is done on top of the existing Android operating system that you are using, and most people like to get root on Android by flashing SuperSU one way or another.
There are a few ways to get SuperSU running on the Samsung Galaxy A7 smartphone. If you can find a custom recovery that is available for this device, you could flash the SuperSU from the custom recovery image. Others enjoy using Chainfire’s one-click rooting tool. Namely, CF-Auto-Root to help install and enable the SuperSU for them. Chainfire’s CF-Auto-Root is not just for lazy people either. Some people prefer having a rooted smartphone without a custom recovery installed. Those individuals who do prefer no custom recovery and own the Samsung Galaxy A7 smartphones enjoy what Chainfire offers with CF-Auto-Root.
