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 guys,
90% of the time my phone doesn't turn the screen off when my face is against it. I think it does work about 10% of the time.
Anyone else have this problem? I think the sensors are faulty because the auto dim doesn't seem to work all the time either. Sensors are to the right of the ear piece, correct?

Do you have a pravacy screen protector?

Do you use Bluetooth? Several people, including myself, have reported issues with the proximity sensor when using bluetooth.
I had the same problem with my torch when having on a privacy protector.

Cases or screen protectors that are to near the prox sensor and light sensor cause problems with all phones.
Its not my case, I'm pretty sure of that. and I don't have a screen protector. I do use bluetooth all the time though.

Do you see the "red dot sensor" that only appears and turns on at the top of the phone during calls?
Fir troubleshooting, place a call and put your finger or thumb over the sensor. Does the screen turn off?
If any light creeps by that sensor during the call, the screen will pop back on...

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.

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.
Alright thanks for answering my questions. Lol

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.
What is that black oval shaped space on the white version of our phone (below and to the left of the earpiece). I think I can see "something" on my phone in that area but it's not nearly as large as what's on the white one. I'm thinking the light and/or proximity sensor, but if so why so large on the white one?

So I noticed on my droid sms if I turn my auto brightness off and keep my screen on the brighter side and tilt the phone a certain way I see a green dot. When I til it to the right I see green, then red. The other way I see red then green. Straight on and if I tilt the top of the phone towards me the dot is no longer visible. I doubt its a stuck pixel due to how it acts. It is NOT visible on black or any other color from normal viewing angles. I saw a similar effect on my Razr HD when I had an otterbox on it due to a weird texture on the screen protector. Thanks for any help!

Do you have a case that is putting pressure on the back of the phone. Dots appearing are usually from pressure being pushed on the back of the phone.

I have the seidio surface case, but its literally like the size of a pixel. Its there without the case on as well. I remember seeing someone post about the HTC One having a similar problem and came to the conclusion it was an abnormality under the glass in the glue or something. I have a TINY piece of dirt under the digitizer as well but every other DNA I have owned had multiple dead and stuck pixels, horrible capacitive button bleed, backlight bleed, or extreme uneven backlighting. Most of these were a combination of pixels and backlight. So I'm keeping this one, just wondering if anyone else noticed this.

Nvm? I just find it odd it disappears at normal viewing angles. On my 32" from a few years ago I have a stuck green sub pixel and its only visible if I look directly at the screen head on. It wouldn't only appear at an angle if it was a stuck pixel, right? It also seems when I use Auto Brightness it is almost impossible to find, even at an angle. Its still there just need to use shaper angles. Its also a LOT dimmer than say, at 50-100% in the dark. During the day its almost not there when the screen gets brighter. In the sun it looks like there might be something above the spot but I'm not sure. Anyone else having this issue? It took me almost a week to find it.

I didn't read your entire post.
Anyway, the pixels are so close together I can't imagine it being too noticeable. If you can see the green pixel at a certain brightness keep it at that brightness and run a dead pixel fixer.
Sent from my HTC6435LVW using xda app-developers app
Well its not thay I see a green pixel. When I look at the screen normally its not there at all, at any brightness. If I tilt it away from me and to the left or right the dot becomes visible. To the right its green and then red if I tilt it farther. If I tilt it to the left it goes from red to green. They aren't bright. I had a DNA with a stuck green pixel and a stuck red one and this definitely isn't a stuck pixel. If it is, its news to me. They were obvious on everything. This one can't be seen unless I view my phone from an angle.
Sent from my HTC6435LVW using xda app-developers app
Edit 2: I don't recommend it but you can rub the screen with the cap of a sharpee wrapped in something soft. This can damage the screen, so its up to you to try. I wouldn't worry about it if you can't see it during normal usage though.
Edit: you'll obviously have to rub kind of hard but use your best judgement.

I don't think its a problem unless your usually looking at your phone at an odd angle. If it really bothers you, you can always try to get a warranty replacement, but I severely doubt they would replace your phone for one broken pixel.
Sent from my HTC6435LVW using xda app-developers app
Yeah, plus I'm 99.9% sure its not broken or stuck... Again because it works on all colors like it should. I was just wondering if anyone else experienced this odd occurrence.
