Most Android-powered devices have built-in sensors that measure motion, orientation, and various environmental conditions. TYPE_LIGHT, Hardware, Measures the ambient light level (illumination) in lx. Phone position during a call.
The natural orientation for many tablet devices is landscape. Another point to understand is that your application must not assume that a device's natural (default) orientation is portrait. And the sensor coordinate system is always based on the natural orientation of a device.
1 This sensor type was added in Android 1.5 (API Level 3), but it was not available for use until Android 2.3 (API Level 9).
The data delay (or sampling rate) controls the interval at which sensor events are sent to your application via the onSensorChanged() callback method.
My phone is the Droid, and it features an accelerometer, a proximity sensor, an ambient light sensor, and an e-compass to name a few.
However, there are times when you may want to know what the status of your phone’s GPS system is – such as how many salites are transmitting, your current GPS directly and location and more. Many GPS-enabled Android apps simply connect to GPS salites and initiate the application with your location. The GPS Status app taps into your GPS receiver and provides you with all of that information in a very cool graphical format.

Android tablets and smart phones come with a number of inbuilt sensors. here we look at the Light sensor – Detects intensity of ambient light.
When you are considering purchasing a new android phone or tablet or using android for a particular task, then you will need to ensure that the device supports the required sensors.

Naive question, but when I check the specs of a phone, one website says phone has feature Here I am interested in the ambient light sensor.
If you call someone, take a look at the front of your phone. You will see a steady red glow from the top left of your screen, this is where the proximity and ambient light sensor are housed.
What does it look like, and where it is usually placed?
If GSMarena has said that it has light sensors, then in my experience, its near 100% correct.
This is covered at XDA Developers forum thread: Where is the One X's ambient light sensor? By Tiersten:
FYI: HTC ONE models S, X, V, EVO 4G LTE are very much alike in physical conception.

For comparison the text says I should see the proximity sensor too.
Proximity On Android, returns number of centimeters distant Not. Ambient Light Sensors Implemented as multiple photodiodes.
