Google doesn’t think you need this because it feels it has offered all the features required to make a good operating system without having it, plus there are complications that can arise when you have a rooted operating system, such as malware being able to jump the “fence” of an application. Root access is having administrative permissions on the Android operating system. The Android operating system would naturally have what is known as root access all the time if it weren’t for Google choosing to take it away from people before they ship the OS out to devices. The difference between a root application and a non-root application is that without root access to the Android operating system, the root applications cannot operate-you can install them, but when you go to run them, they won’t be able to run without root permissions. A minority of those are root applications.

Today there are about 3.5 million applications available on the Google Play Store, surpassing the 1 million mark back in 2013. This is what you need to root your smartphones and tablets that are running on the Android 8.0 (Oreo) software update by using the SuperSU application and a custom recovery image.
