The practice of locking a device to run only one specific application is a configuration setting on the Android operating system. An example is a point-of-sale system at a retail store, where the tablet is solely dedicated to processing transactions. This ensures the device’s resources are focused on the essential function.
This restricted operational state enhances security by limiting the attack surface. It also streamlines the user experience, preventing unauthorized access to other applications or settings and reducing potential distractions. Historically, this approach has been employed in environments requiring focused functionality and controlled device usage.
