The word “root” definitely brings a smile to Android users' faces, but what does this actually mean? A veteran Android user might tell you that it means only the beginning and that really isn't too far from the truth. We've already covered what rooting actually means in detail in our rooting guide for dummies and in our layperson’s dictionary of rooting terms, but what it basically means is that you can regain administrative rights to your phone.
What you get out of the box isn't the device's full potential but you can set it free by rooting it. Back in ye olde days, rooting was a tricky process that scared newbies away. Though it might still prove to be scary for some particularly hard-to-root phones, the rooting process nowadays has been simplified so that even newbies can get started on enjoying their device's true power.
