There is only one way to have full control over your Android operating system and that is with root access to the internal system. You need access to the root file system to do many tasks like remove the stock apps, make changes to any core system files, change boot images and do a number of other important tasks.

By default, your Android operating system is unlocked by default — and by unlocked OS we mean it originally has what we call root access. However, Android developers lock it up because it’s safer for the general population. It’s safer because it isolates any malware and locks it so no apps can talk to each other.
