Smudge detection coming to future iPhones?
Submitted by Frank Macey on
Proximity sensors on future iPhones may be more sophisticated than current components. According to the patent titled Proximity sensors with smudge detection capabilities, malfunctions due to dirt on the display can be prevented. Sometimes a smudge on the glass will prevent the proximity sensor from switching the display on. The problem is the sensor believes the iPhone is against the user's head.
