Google Android reigns among the operating systems for touch screen mobile devices: tablets, watches and especially phones.
The operating system is what makes the device work, as Windows for Microsoft in personal computers.
According to Gartner, the Android system, created in 2007, is the clear predominant in the world of mobile telephony, with an order market segment of 85.9% (data for 2017), compared to around 14% for iOS, the Apple operating system for iPhone and iPad and 0.1% for "other mobile operating systems".
