iPhone 4 PROXIMITY SENSOR GLOWING RED when on call!!!

No problem. It seems a lot of threads have trash talk in them. Don't know what is wrong with people today.

What legitimate sites are reporting this?
Nothing on Engadget, cnet, macnn, tuaw, maclife, macworld.

Where are these pictures posted on legitimate, credible sites?

And where EXACTLY do you see the "glowing LED"?

I just took a picture of my PS a minute ago. The light is very low intensity, and absolutely invisible to the naked eye. It definitely doesn't glow.

P.S.: I wouldn't trust any of the "pictures on the web" - any CCD sensor will record invisible IR spectrum and show it as ~white light depending on the intensity. Look at the pic above - The light you see is invisible.

uh, I just made a call, went into a pitch dark closet and I could clearly see a red glow coming from the proximity sensor....

what part about that is "absolutely invisible?"

Haha at the photo link above. Yes the sensor can be seen just but it is no good trying to take a photo of it as all digital camaras are sensitive to ir light. Try to take a photo of the emitter on the end of a remote while pressing one of the buttons lol

what are you talking about?

I was in a dark closet and saw it with my naked eye...not with a camera.

Nobody is stating that they can see infra red, they can just see a red light where the IR diode/emitter is. Face facts, this red light is visible to the naked eye since 4.1

If you read my post I said you can see the sensor but only just. But just because you can see visible light does not indicate a fault I have two large infrared flood lights for my security camaras and you can clearly see ever IR led emitting visible light and they are 10 years old and still working.

The point I was making is that there is no point taking photos of the sensor as it will appear 200% brighter than it really is

Dude too much Ear Hair in the pic. : )

I just checked my 3Gs running 4.0.1 and I also have a red dot when placing a call.
Sometimes I think people are just looking for stuff to get upset about. Nothing to see here folks (except a red dot that was there before the update).

It wasn't there before the update...

I checked my 2 IP4's; one upgraded to 4.1, the other not yet. Yes I can see the red glow (with my eye) on the 4.1. I guessed people complained the PS wasn't working well, so one thing is they up'd the current to the LED to give more range.

Not to worry. Most NIR LED's have a small emission in the visible too. This is normal. So you can see it now with more current drive. All the light levels went up...it is not 'burning' or glowing red!. But still the lifetime, even at these conditions, is 100K hours. And it is not on continuously (even when on, it is pulsed at Khz rates). I work daily with these devices, I know a bit about them.

100K hours is a long time. And with the 1 year warranty, if it fails, Apple will replace it.

People should just think of it as.... Hey, this light means my PS is currently active, if it goes off, its not 😟

I agree. 100K hours is 11.4 years of continuous use. I wouldn't worry about it, if it fixes your PS problem.
