The ambient light sensor is a power saving feature. It measures the luminance value of the light (think a camera with a very low resolution that can only measure brightness)
The darker the environment, the less backlight you need so it automatically lower the backlight brightness.
Here is a picture of one that you may find in a smartphone: i.imgur.com/eWPH9.jpg
If you would like to know the info that your light sensor is picking up (and have an android phone), then you can download the phone tester app then look at the sensor data. play.Google.com/store/apps/details?id=com.mtorres.phonetester&hl=en
The phone's camera could be considered a light sensor, but you could be referring to the light sensor, which tells the phone to dim the screen when the surroundings are dark. This is achieved through a photocell or photosensor. In simple terms, they are variable resistors, whose resistance is proportional to the amount of light hitting them.
It has capacitance type

no only mobile phone can communicate lights can't. :)
It depends for exaple some chargers have a light on it, that takes energy not much but it does other then that no.
light sensors are used in cars, televisions and computers. there are different types of light sensors.
When you are charging the phone, it will often light itself up to indicate that the charge is complete. Some phones light up as a reminder of missed text messages or phone calls.
Light sensors measure the number of photons or the energy of light hitting the sensor.
One can purchase a white mobile phone at Light in the Box. These color phones are also available at Boostmobile, Best Buy, Walmart, Samsung and Sprint.
mobile phone can use for everthing . However ,mobile phone have disadvantanges. By using a mobile phone . we use the mobile phone to communicate or browsing the internet .the disadvantages by using a mobile phone is we always waste the time with the mobile phone to play a game or when the mobile phone have internet , we do not do anythings just sit and play .

Very light. Probably around the weight of an average mobile phone.
A mobile phone tariff it cost of any transaction made on your mobile phone.
