Yaw, Roll, and Pitch are the angular moments seen from three axes i.e. It also detects the roll, pitch and yaw motions. right, left, up, down, forward and backward. When 'Gyros' used along with accelerometer senses motion from six axes i.e. This sensor's function is to maintain and control the position, level or orientation based on the principle of angular momentum. Thus, by use of multiple sensors put across different orientations and using a disk/magnetic concentrator (with high permeability material)which bends the lines of the magnetic field which are parallel to the plane of sensor plane this can be attained. This can be possible by the 'Hall effect'. If ultra low-frequency signals coming from a specific direction like North or South and with the help of an accelerometer, the sensor can calculate the orientation and direction. But due to interference in communication, the smartphone does not use the magnet as one of the components in the compass sensor but it uses new technology that does the same work as a conventional compass does. We all know that the function of the compass is to give the right direction with respect to the north-south pole of the earth by the use of magnetism. One can better use this feature/sensor while playing racing games where he/she can steer the car in the desired direction by leaning the phone in that direction.

Ultimately this accelerometer sensor senses the change in orientation by 3D (X,Y & Z axis) measurement of the acceleration of the device with respect to free fall. Similarly, camera mode also changes the portrait to landscape or landscape to portrait mode when we change the orientation of phone/camera. For example, when you are looking for a web-page with increased width, you can get this landscape view from changing the orientation of the phone to horizontal. The main function of an accelerometer is to sense the changes in the orientation of the smartphone with respect to datum and adjust the orientation to suits the viewing angle of the operator. They contain photodiodes that are sensitive to the different spectrum of light and combined mathematical effect adjusts the gain and output changes of the light intensity on the screen. Ambient light sensor senses and adjust the light based on the principle of 'superposition'. The ultimate function of an ambient light sensor is to adjust the display brightness, which in the end saves battery power and life too. This sensor optimize the light of the screen when it exposed to normal light with different intensity.

iPhone 4S, iPhone 5, HTC One, HTC Droid DNA, HTC One X, Samsung Galaxy series smartphones, Sony Xperia, Nokia Lumia 620,820,920 and 822 and many more smartphones support GLONASS (Globalnaya Navigatsionnaya Sputnikovaya Sistema) GPS system for navigation purpose. Nowadays smartphones come with assisted GPS or A-GPS which does the same work with the help of intermediate server in case of disconnection with main GPS satellite. GPS is a system which tracks the target or 'navigate' the things by map or picture with the help of GPS satellites. GPS short form of Global Positioning System originally developed and set up for military operations and was made available for everyone in the 1980s by Government. After the conversation, it resumes the same function which was stopped earlier during the talk. Thus, in a nutshell, a proximity sensor detects the presence of the body like cheek, face or ear and stops web surfing, music or video during talk/calling and saves the battery. This sensor also detects the signal strength, interference sources and amplification or filter by use of the Beam Forming Technique. Also, proximity sensors stop the accidental touch, unwanted input during the talk. When you use your smartphone, it detects the position of the ear with respect to the screen and turns off the light of the screen and saves battery. The main function of this proximity sensor is to detect how close your smartphone's screen is to your body. Let us understand how each sensor works with respect to its operating principle.

Different types of sensors like accelerometer, ambient light sensor, GPS sensor, compass, proximity sensor, pressure sensor, gyroscope etc are behind these smartphones. One of the feature that attracts the mobile phone buyer is the smart work it does. Today different manufacturers like Samsung, Apple, Sony, HTC and many more manufactures of smartphones and became competitors. These new features and specifications gain enough fame of users to survive in the competition of mobile technology.

Since the beginning of race in mobile communication, a new model is being launched every day into the world with different features.
