So you own the Samsung Galaxy S5 smartphone and continually hear about this thing called root access and want to you why people even bother. The answer is simple: because it is what you need to have if you are going to be the administrator of the operating system and use any files that you want.

Anyone who has bought a computer themselves that runs on the Windows operating system will have set it up and automatically been handed over the reigns to be the administrator. That is because Windows decide the owner of the computer deserves to be the administrator, and it is their responsibility to look after the rest regarding keeping malware from the operating system.


Android developers have a different view, and they have decided that the first person who turns on the device and sets it up does not get to be the administrator (or what they call a root user). They do not want to take any chances of you installing malware, so they keep you confined to the locked operating system which is an operating system that traps malware if you download it.

Thankfully, there is a way out of all of this, and that is by rooting the device. Many smartphone carrier networks choose to make rooting difficult to achieve, but others do not. By rooting the Android operating system, you are getting control of the root user account which then gives you the power to decide what stays on the device and what goes. That means you get access to any of the files and have the chance to remove any of the apps that you do not want taking up memory space. Additionally, it means you can have access to the thousands of other apps out there in the world that existed but would not run on your device without it knowing that you have root access first.
