It's the software that enables task execution, app operation, and communication with your phone. With distinct features, Apple's iOS and Android are two widely used mobile operating systems. Many people, including OnePlus, use Android. The operating system ensures a flawless experience by handling everything, including hardware resource management and the touch interface. It's an essential component of your phone that silently functions in the background to ensure that everything works properly and that you can get the most out of it.
