An IT technician is tasked with gaining root access to an Android device for a corporate client, in order to remove pre-installed software and install custom security applications. Which of the following should the technician be most aware of before proceeding with this task?
The device will automatically receive Android updates faster once it is rooted.
Rooting is only possible on older Android versions (4.4 KitKat and below).
Root access is only available through third-party applications found on the Google Play Store.
Rooting the device may void the manufacturer's warranty and expose the device to security risks.
Correct Incorrect Unanswered
Answer Description
Rooting an Android device gives the user root-level access, allowing them to alter or replace system applications and settings, run specialized apps, and perform other operations that are otherwise inaccessible to a normal Android user. However, this process may void the warranty and potentially expose the device to various security vulnerabilities. It's crucial for a technician to understand these implications and communicate them to the client before proceeding.

Rooting is the process by which users of Android devices can attain privileged control (known as root access) over various subsystems of the device, usually smartphones. Because Android is based on a modified version of the Linux kernel, rooting an Android device gives similar access to administrative (superuser) permissions as on Linux or any other Unix-like operating system such as FreeBSD or macOS.
Rooting is often performed to overcome limitations that carriers and hardware manufacturers put on some devices. Thus, rooting gives the ability (or permission) to alter or replace system applications and settings, run specialized applications ("apps") that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. On some devices, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system.
Root access is sometimes compared to jailbreaking devices running the Apple iOS operating system. However, these are different concepts: Jailbreaking is the bypass of several types of Apple prohibitions for the end user, including modifying the operating system (enforced by a "locked bootloader"), installing non-officially approved (not available on the App Store) applications via sideloading, and granting the user elevated administration-level privileges (rooting). Many vendors such as HTC, Sony, OnePlus, Asus, Xiaomi, and Google explicitly provide the ability to unlock devices, and even replace the operating system entirely. Similarly, the ability to sideload applications is typically permissible on Android devices without root permissions. Thus, it is
