Mobile operating systems (OS) are the heart and brain of our smartphones, controlling everything from app performance to system security. Among all mobile OS platforms, Android and iOS dominate the market, each offering unique advantages and features. This blog explores their architecture, app ecosystems, privacy controls, and more—so you can understand how your phone really works, and which OS suits your lifestyle best.
1. What is a Mobile Operating System?
A mobile operating system is software that allows smartphones, tablets, and other mobile devices to function. It manages hardware resources, provides a user interface, and supports applications. Popular mobile OS platforms include:
- Android by Google
