Proximity Sensors in Android .

* The Proximity Sensors either measures the distance that some object is from the device ( in

centimeters ) or represents a flag to say whether an object is close or far.

* The Proximity sensor is sometimes the same hardware as the light sensor.

* The Proximity is often used in the phone application to detect the presence of a person's head

next to the device.If the head is that close to the touchscreen,the touchscreen is disabled so no

keys will be accidently pressed by the ear or cheek while the person is talking on the phone.
