Rooting, aka Superuser, is used to expand the functionality of Android operational system.
With root access you can:
- Disable firmware upgrades or revert to previous firmware version
- Remove adds from your apps
- Delete built-in apps and sounds
- Build in apps and sounds
- Change the look of Android beyond recognition (change icons, background), edit apk and system files
- Extend the life of your battery’s charge (if one charge lasted you 1 day, then with root rights you can increate it to 1,5 – 2 days)
- Improve the performance and responsiveness of your device
- Make your processor work faster or slower
Disadvantages of rooting your device:
- No way of automatically getting official firmware upgrades (you can do that manually)
- Disabled brand perks from the developer
There are several types of Android rooting:
Full Root – permanent root rights that can’t be undone after you reboot or in any random way, there’s also an ability to edit system
Shell Root – also permanent root, but unlike in Full Root you can’t edit system
Temporary Root – temporary root access that disappear when you reboot your device.

When you get root access you automatically loose warranty repair! But don’t despair, after you get root access you can also secretly remove it so no service center can refuse fixing your device.
