Basic functionalities of mobile phones have changed from mundane activities like call, SMS to performing the tasks like navigation, tracking etc. which has made mobile units smart. This has become possible due to the introduction of sensors. Sensors enable a mobile phone to be context aware i.e.; aware of the environment and activities of phone and its user. Sensors are of various types and each of them has a different functionality e.g.: magnetometer, accelerometer, proximity, camera, Wi-Fi, gyroscope etc.
