The practice of replacing the default operating system of a mobile device with a full-fledged Linux distribution is a significant modification. This involves overwriting the original software environment, typically Android, with a system like Debian, Ubuntu, or Arch Linux. As an example, an individual might choose to replace the Android operating system on their Samsung Galaxy Tab with a version of Ubuntu designed for ARM architecture.
This alteration grants users increased control, expanded software compatibility, and the potential to repurpose hardware for tasks beyond the scope of the original OS. It enables running desktop-class applications, facilitates development activities directly on the device, and opens doors to a wider range of security and customization options. Historically, this process has been driven by enthusiast communities seeking to overcome the limitations imposed by manufacturers and carriers.
