iPhone 4S Proximity Sensor Replacement
Proximity sensor is an important part in the smartphones of current time. Previously in the feature phones, no matter low or high end, the backlight used to stay on till a certain period and then it would go out. In the smartphones however, whenever someone makes or receives a call and put the phone to their ears, the phones display turn off and it doesn’t take any touch feedback either. This prevents the phone from taking any other command while making a call, also a possible interruption won’t happen because of this useful sensor.
