The action of starting an Android operating system from a Universal Serial Bus device constitutes a method for loading and running the OS from an external source, rather than the internal storage. For instance, an individual might choose to initiate their Android system from a USB drive containing a customized or alternative version of the operating system. This capability offers a degree of flexibility and control over the system’s software environment.
This approach presents several advantages, including the ability to test or utilize different Android versions without modifying the primary system installation. It also provides a solution for data recovery or system repair if the internal storage becomes inaccessible or corrupted. Historically, this functionality has been vital for developers and enthusiasts seeking to experiment with custom ROMs and kernels, or to deploy Android in environments where persistent storage is undesirable.
