Okay so during a phone call there's this red light next to the front facing camera, once the call is over it disappears!
Are we bring recorded?!!? Lol
But seriously does anyone know what the red light is and/or why it is there?
Thanks in advance

It's not a light at all, it's the proximity sensor.
Lol whats with all the conspiricys on here lately
The proximity sensor doesn't light up. Its the infrared light for the sensor.

AT&T is recording all your phone calls and sending the information to companies so that you can get more personalized results. It's part of the terms and conditions that you sign...Now, you can be talking to your friend about these new jeans you really want to buy, end the call, and boom, Amazon's link to that pair is ready and waiting.
@yahoowizard: I knew it!!! LOL
@quarlow: Figured, just wanted to have a fun thread! LOL
Some people have better near-IR sensitivity than others... Just like old people have less sensitivity to high frequencies than young, leading to some old fogeys using "squealers" to implement "get off my lawn!".
The light during calls is the near-IR component of the prox sensor. It's how the phone turns off the screen and disables touch when your face is next to it.
This thread made me laugh.

So first time I noticed this...looks like its the proximity sensor
If u have the phone in a dark room u can actually see a tiny little red light next to the left of the ear piece...thing is u can only see it when then phone is strait up and down...vertical u know
I think it senses u holding the phone strait and anticipation of holding the phone to ur ear

If there is no light available I would expect it to emit some that way when it gets a reflection it know to kill the screen.
Just my opinion of course

I was just about to report it. Yea I guess it is for night time
Night light, lite brite, etc.
I think that's for the in pocket detection option where ur phone locks itself when. Inserted to a pocket or something

Has anyone else noticed a red light near the speaker (the one you put up to your ear) on the left side above the (proximity?) sensor? I have had my rezound just over 2 months and noticed it for the third time today and am courious what it is.

yep it's like an RF signal..that's the proximity sensor
Yeah it is the proximity sensor. It uses IR... sometimes when it is on full power you can see it is dim lit areas.
Also has the lught sensor in it for auto screen brightness..
Oh ok, makes sense. I was confused because I only got to see it a few times. Thanks guys.

Hey I just want to ask what this little red light that turns on when the screen is on, it's the one beside the earpiece on the right side.
This is on my mom's phone so I won't know what this is, hence the question

Touchwiz uses the proximity sensor doesn't it? AOSP roms do not. It doesn't light up on my S3 with an AOSP rom.

Mines never lit up, on stock or any custom rom. I'll check again maybe when it comes close to the head it comes on.

What's funny is I have the exact opposite situation, I have all motion options disabled but occasionally see it, I can't remember when I see it and under what conditions so I'll post back when I have more useful info. It looks like an infrared light so I'm wondering if it might be able to take commands from another device.
Here are links to 2 other forums speaking about this issue:

Guys the question has already been answered in the 2nd post. Its the proximity sensor and it can light up on different occasions, such as during calls and possibly in text messages etc if you have direct call enabled.

We all read it thanks for pointing it out. We are talking about it's lighting up or not lighting up in what conditions.... NOT what it's supposed to do, do read the comments above urs.
He was referring th lordazoroth who believed it to be a infrared emitter/receiver.

Ok. Let me make it a bit clearer for you. When your in a dark environment, dial a number and it will turn on. If direct dial is also on, when you put it near your head, as it starts to dial remove it and you will also see it lit. Nothing more nothing less as far as I know. The reason most people don't notice it is because the light is very feint and on most occassions can't be seen.
Sent from my GT-I9300 using xda premium
Alright I have more information, I do not have direct calling enabled so when I'm texting the light does not turn on. However when I'm in the middle of a call, I'll see the little red dot light up faintly and the screen will turn off when my head gets close to it. Interestingly enough, there is a cone of detection coming from the light (or directly next to the light). When I move my finger within the cone of detection, projecting from the light, the screen will turn off. When my hand or head is close to the phone without blocking this cone of detection, the phones screen will not shut off. I would assume that due to how dark my testing conditions were (including the screen being nearly pitch black), this would appear to be an infrared detection system. Therefore it should serve any purposes in which proximity detection is needed, including direct calling and automatic screen control. If a program were written, I'm guessing this infrared sensor could be used for any number of things, including remote control and even data transfer.
Interestingly, my Nexus S 4g seems to have a very different detection system, there is no tiny red light nor is there a cone of detection projecting from the front. Instead when anything sizable comes near the top of the device (from the front, top, and/or back) the screen shuts off during a call, which indicates some type of field detection. I'm guessing these two devices have different proximity detection systems either for power conservation, cost of manufacture, or both.
Its proximity sensor. . . Don't worry its not causing any harm. and near to this is RGB sensor.

Thanks, i was thinking it would be easily visible but it's really faint light and visible under dark conditions only. My guess is it might be infrared light for the sensor. I used to have night vision option in video camera and could see bright light coming out of remote controls dont' know where i placed my old handy cam but if someone has it they can test it out and see if it emits IR light as well.
So I just got off the phone with my girlfriend, I'm hitting the hay early tonight, waiting for her to get home and she just called me so I put it on speaker.
Then I noticed there is a faint little red LED on the left side of the phone right above the screen, it went away when the call ended but I never noticed it before.
I know the OG EVO 4G had 2 LEDs, CM made the second one useful, but idk about the 3d or other evo phones.
I should note i am in a pitch black room and this led is about 1/3 of the size of the notification led. Also is extremely dim, almost looks like a red circle.
Kind of cool
Wondering if anyone else has noticed it

When I have a Google Now notification, which is almost all the time, the notification lights blink. And since the lights only come with three colors, and it seems almost all notifications use the SAME color, I never know if it's flashing because my battery is low, if I have an email, text, or a Google Now notification, missed call, voicemail, etc!
If only Lightflow worked on the stock DNA, then I could at least change colors for some of these things. So irritating.

I have to agree, especially because the light is so dim, I never notice it unless I'm staring right at it.
agreed. i also think that the same led powers both lights. I could be wrong, but they are useless for me as well
Personally I LIKE the fact that they are useless. I hate annoying blinking lights.
They do shine fine in the dark I guess.

The point isn't whether you prefer notification lights or not but that HTC chose to implement them and therefore it is reasonable to expect them to serve their purpose adequately, which they don't. They truly are almost useless being as dim and color-unchangeable as they are (not to mention how far recessed into the speaker grill the front light is).

They could've been a tad bigger imho... I rarely even notice it flashing until I actually pick the phone up and look at it... And at that point I mine as well turn the display on to check. Lol

ummm yeah.... the notification light isn't exactly HTC's strongest feature.
I like how they tried to implement them, I like them on both sides and think it could be very well done. With that said they are very dim and pretty weak so they aren't that useful.
I personally find it rather useful for certain things. I often have my phone face down (which I feel is the position it was designed to sit in) and the rear notification light has been really helpful this far.

instead of blinking, some notifications would stay a solid color even after making it set to blink. some colors would show up as other colors. horribly, awful battery drain.
lightflow was great on the gnex and terrible on the s3.
Wait, I was unaware the notification led was 3 colors? What are these colors? I'm assuming green, orange, and...?
I'm getting the phone tomorrow though

I guess my main problem is the fact that the led comes on even for Google Now notifications, and I have those on all the time. I can somewhat live with the limited colors, but because the light comes on for Google Now (and like I said, I always have those on), I never know if I have any other notifications because the light is always blinking.
