The HTC Touch Pro2 is a great device as you have no doubt seen from the online reviews. What can sometimes be missed are the little features that are present on a device, but you just take for granted or do not really think about, how do they work.
One such example is the HTC Touch Pro2’s proximity sensor.
The Pro2 is one of very few devices to have a proximity sensor, which turns off the display when you are on a call to preserve battery.
When you move the phone away from your face, the backlight will then come back on again so that you can use the functions of the machines etc.
The video below gives a quick demonstration of how it works.
