When a person uses Android with root privileges, they are using the root user account. The root user account is nothing new to Android; it always exists in Linux and the Android operating system is based on the same Linux kernel. Being able to get in control of the root user account is important; without it, you wouldn’t be able to install any apps that you want, and you wouldn’t be able to uninstall any apps that you want. It’s critical that developers have access to the root user account.

Android and Linux both comes with a root directory which is the name given to the top level of the directory in the system. With access to the root directory, you can then access all files and run all commands. Without it, you cannot. Another way of looking at it is it has full write permissions over the root directory. In practical terms, it is the applications that often need to have these write permissions so they can do the things they need to do for them to be able to run.

Take the Titanium Backup application for example. Many apps help you backup a device and those who haven’t been introduced to rooting the Android operating system to get in control of the root user account will be happy to find out about apps like Helium that makes backing up application data easier. However, the Helium app is not close to competing with the Titanium Backup app for one reason: Titanium Backup has the extra power to be able to read all apps data thanks to having access to the root directory which is something the Helium app does not have access to at all.

In conclusion, that is how to root the Samsung Galaxy A5 SM-A510K smartphone running on the Android 6.0.1 Marshmallow software updates by flashing the SuperSU by Chainfire with the help of the CF-Auto-Root tool. The rooting tool has just had to install a modified cache and recovery to help get the SuperSU correctly installed so it grants the rooting permissions to the apps that need it, and it had removed the recovery and cache that it needed to install to get that done so your device is left the same way it was before the rooting started. The only difference is that you now have the SuperSU program available as an application from the app drawer.

The SuperSU being installed and enabled on the Samsung Galaxy A5 smartphone means that you can start installing any of the applications that are out there and available for your device. Well technically you always could do that, but not all of them would run. Now they all run and it is just up to you to grant the rooting permissions to the apps that are trustworthy and not to install any of the apps that are not. The SuperSU blocks root access by default to everything you install and it is only when you want to run an app that SuperSU then prompts you with a message on the displaying asking for your confirmation for that app. When you think of it like that, the security is no different to a computer. If you wanted to create an exception to run an application on a Windows operating system on a computer, then you could do that from the antivirus if it was blocking it. The SuperSU does block everything by default too, so nothing gets root access unless you confirm it when it gives you the chance to do so on display.
