Proximity sensor

The proximity sensor is used to turn off the touch input, when the phone is against user's ear during call.
This prevents accidental touch signals that could happen when, for example, user's cheek touches the phone.
The main parts of the proximity sensor subsystem are:
• Proximity sensor
• Proximity boot (mechanical part)
