The Android operating system is a mobile operating system developed by Google primarily for touchscreen devices, cell phones, and tablets. Its design allows users to manipulate mobile devices intuitively, with phone interactions that mirror common motions, such as pinching, swiping, and tapping. In addition to mobile devices, Google employs Android software in televisions, cars, and wristwatches, each fitted with unique user interfaces.
