<p class="MsoNormal">A proximity sensor deactivates the display and touchscreen
|
|
|
8 |
when the handset is brought near the face during a call. This saves battery
|
|
|
9 |
power and prevents unintentional inputs from the user's face and ears.
|
|
|
10 |
Proximity sensor in some handsets (like BlackBerry) also senses cases and
|
|
|
11 |
holsters to detect whether the phone is in or out of the holster. This
|
|
|
12 |
technology in such phones allows users to modify different notification
|
|
|
13 |
settings when the phone is inside the case.</p><p class="MsoNormal">See Also</p>
