3G iPhone proximity sensor
In April, specifications were allegedly leaked from Hon Hai/Foxconn offering users a glimpse of the then-unreleased 3G iPhone, showing a third sensor, which has now been confirmed. iLounge writes that the 3G iPhone features an ambient light sensor, as with the previous model, but also two proximity sensors, which sources indicate is to improve face-detection functionality. The original device reportedly had issues dimming the screen when a phone call was answered using the handset.
The sensors are located together in a 'J' shape to the left of the phone speaker, originally spread above and to the right.
