What are root-rights on Android and why are they needed?

If you use a device based on the Android operating system, for example, a phone or tablet, you may already have heard the word Root or Root rights. We’ll talk about what it is right now..

Root is an administrator or superuser account that allows you to do a lot of things with the device that are inaccessible to the average user. So, if the owner of the device wanted, for example, to raise the sound level when the current settings are not enough, he can do this with root rights.

What Root Rights Do?

  • First of all, the user gets unlimited control over his operating system..
  • There is an opportunity to launch applications that provide access to work with the system. For example, these are file managers who, in the case of installed root-rights, see absolutely all system files and allow you to edit them.
  • The ability to remove third-party applications is added. It is no secret that many manufacturers who use their own shell often literally “stuff” a bunch of applications into it, which are often not used in the future. Some of them even start up together with the device and “eat up” extra resources. Root rights allow you to remove or freeze such applications.
  • With root privileges, you can modify system files. For example, you can replace standard applications, icons, system sounds, animations and images that are displayed at system startup, etc..
  • It is also possible to transfer applications from the device to the memory card, which is especially convenient in cases where the system memory is only a few GB.
  • You can backup the entire system using popular applications such as Titanium Backup.
  • Using the settings of some parameters, you can even extend the battery life of your tablet or phone..
  • If you forget the graphic key, then in some cases it can be unlocked using root-rights.

In general, the possibilities of the supervisor are a great many.

Why root rights are not embedded in the Android OS?

It is a logical question. Indeed, why are devices from the factory delivered to consumers without established root rights? In fact, everything is simple: the bulk of users can accidentally change settings not where it is required, after which the device may well turn into a brick.

However, some users have a different opinion. They believe that the root allows you to remove ads in applications. Maybe this is true, it’s only through advertising that application developers primarily earn money, to which Google (the actual creator of the Android OS) has no relationship.

By the way, many manufacturers refuse to repair the device if root rights were obtained on it. Moreover, they began to install a special counter in separate kadzhets, which even in the case of a flashing shows that the device has previously been rutted. be careful.

Types of root rights

There are several types of root rights.

  • Full Root – full and permanent rights without any restrictions that allow you to access all the tools of the system.
  • Shell Root – in fact, these are the same Full Root rights, only in this case there is no possibility of recording and rewriting in the system section.
  • Temporary Root – these are temporary root rights. Validity – until the first reboot of your tablet or phone.

Please note that it is not possible to set superuser rights on some devices. The device has special protection that allows you to get either Shell Root or Temporary Root.

Does a simple user need superuser rights?

More likely no than yes. Most users are completely satisfied with the settings that are available in the device they use. Another thing, if the user wants, for example, to limit the processor clock speed, then root-rights cannot be dispensed with. But once again let me remind you that careless action can lead to sad consequences and some companies do not accept devices under warranty if they were rutted.

How to check for root rights on Android?

This is not so difficult to do. There are several ways to do this..

  • First, look at the list of applications, it may have a SuperSU or Superuser application.
  • The second way is to launch the terminal. If you enter the su command, a grid prompt appears.
  • The third way. Go to the / system / xbin section using the file manager. If there is a su file there, then root-rights are received.
  • Finally, when starting some applications, a request for granting root rights appears. If such a request exists, then the device is rutted.
