Which mobile operating system is likely installed on Ana's new smartphone?

The likelihood that Ana's new smartphone is installed with Google Android is high because Android is currently the most widely used mobile operating system in the world. It powers a vast majority of smartphones across various brands, making it a common choice for consumers. Android's extensive market share and its open-source nature encourage manufacturers to adopt it for their devices, resulting in a diverse range of smartphones equipped with this operating system.

While Apple iOS is also popular, it is exclusively used on Apple devices, such as iPhones. Windows Mobile and BlackBerry OS have significantly diminished in market presence and are no longer actively developed or supported, making it improbable for ana's new smartphone to run on either of these operating systems. Therefore, the landscape of modern smartphones heavily favors Android, solidifying its position as the likely choice for Ana's device.
