The mobile OS runs on the device environment with limited resources communication like RAM, storage unit and a CPU. The mobile OS determines the functions and features of the device and also defines various third party apps which are used on the device.
The basic fundamental function of a mobile phone device is communication with help of network. Earlier mobile phones were manufactured to serve this purpose only i.e. text messaging and making and receiving calls.
