Today the leader among operating systems for mobile gadgets is Android. The fact is that since version 4 Android it has become more universal, it is used on smartphones and tablets. But over time, problems appear, mainly related to a lack of functionality, RAM or processor power, and we are striving to get root rights to Android 4 in order to somehow compensate for the shortcomings of the aging device. 
What is root access on Android
Unlike Windows, Android does not provide a user with administrator or superuser rights. Access to the system partition (root disk) of the OS, or root access, is a special mode at the administrator's level, obtained using third-party software.
Having 'issued' such rights, the user gets unlimited control over the device. Of course, with some reservations.

Root access check
It is necessary to make sure that you get root after a rooting operation, which is not always successful. In addition, sometimes a user buys a device without knowing whether it has a root. In any case, verification can be performed in the following ways:
- Manually – using the search for .su or superuser.apk binaries on the device. For this, a good file manager is installed.
- With the help of special applications that do, in general, the same thing, but faster and without effort on the part of the user. Similar programs are available on Google Play. For example, Root Checker and SuperSU are almost permanent leaders in user ratings.
