Status led in iPhone?
In step 10 of the teardown you say, "What appears to be the ambient light sensor and status LED comes off the display assembly."
Could you explain what the "status led" is? Is it equivalent to a notification led?
i want to bring a little bit light into the darkness - the 4s has no status led.
the dark led is an infrared emitting led!
EDIT: thats really funny - is it to hard to understand ? - it's not a notification led.
but to show it to you, here comes a pretty bad picture of it
since infrared light is not vsible - we can't see it
but you can make it visible with a digital camera - pint at the earpiece speaker and wake up the 4gs - et voila - the infrared light is "visible"
Your "Dark LED" is the Proximity Sensor. It is shooting out IR which bounces back and hits a receiver which tells the phone when it is next to your face. That shuts off the screen so you dont inadvertently touch and trigger actions on the screen. Right next to it is an ambient light sensor that the phone uses to automatically control the brightness of the screen to preserve battery life. My question is just over from there there is another hole in the case with an unknown function. It can be barely seen from the front of a black 4S and is invisible due to being painted on a white iphone 4s. The round hole is plainly visible in the teardown and is not in any of the previous phones.
I understand what Barry is saying. I know where the ambient light/proximity sensors are. There is a new hole just to the left of these. What does this do? See the picture below.
