I'm unsure if anyone tackled or even noticed this one yet, but I noticed that after I unlocked the bootloader via htcdev.com, whenever I make a call, there's a little red light that sits above the HTC branding (left of the notification LED) that flickers repeatedly whenever I make any phone calls. Is this a unlocked bootloader indicator, malfunction, or normal function of the phone? Also, can someone tell me what that light is for if it's not an indicator of a call?

I don't ever get the red indicator light unless my battery level is low.
In fact I don't have any LED light while I'm on a call at all.

I'm not saying the notification LED. It's a separate light to the left of it. It's located conveniently right above the right side of the T in the HTC branding. It's very very faint. The only reason I noticed it was because I was in the dark and I pulled the phone away from my face to look at it.

I'm in the dark right now. I just made a call to my work phone. There is no light.
That's a sensor. It turns the screen off when the phone is by your face..(having a brain fart of what that sensor is called) lol

So when that sensor is active, you can see the red flashing it does?
Edit: Well, you seem to have won the cookie. I don't know why my proximity sensor is actually visible. I just tested it with my thumb. Turns out that that is indeed the proximity sensor.
Mine does the same thing only its completly random. I'll look over and it'll be flashing. I decided to just ignore it a few weeks ago.

I noticed this a while a ago it is the proximity sensor, its not next to the left of the ambient light sensor and it is NOT the led!!, go into a dark room and make a call it'll start blinking...or any app that uses proximity sensor...Also if you have the option of pocket mode it'll probably be running all the time but i'm not sure, it should technically run when you receive a call, but you will definitely notice that it'll blink very very rapidly while you're in a call...proximity sensor!!
Whats weird that I noticed also is that when my HTC amaze fell on the floor board of my truck I reached down to pick it up and passed it in front of my Radar detector the L band went off on the radar detector I though maybe a cop out but nope every time i put the phone in the radar detectors view it started going off, pretty weird just wondering if anyone can explain that, it might be the reason its giving off that red glow
It emits infrared light. Some peoples' eyes are better attuned to see it than others. In other words, some people cannot see the light at all, and other people can see it just find - it all depends on how sensitive your eyes are to the infrared spectrum.
yeah i thought i was the only one with this problem. whenever i make calls the light goes crazy even after the call!
hey so after reading this, because i was also trying to find out what it is myself.. i now know what it is..
but recently i noticed that my phone freaked out, and shut itself off, and that red light stayed on.. my phone wouldnt charge nor turn on until
i took the battery out and out it back in.. has that happened to anyone??
Yea I've seen it to

Hi I have just got a HTC radar as a company phone and am getting some odd behavior when dialling
Sometimes it works like expected other times when I press call the screen goes off and will not come back on no matter what I do until the other end pick the call up
Now that's not so bad until you call voicemail when nothing makes screen come on ie tried moving away from anything (in case proximity sensor turning it off ) tried the on/off button volume even camera button nothing works so I can't press option 1/2 etc
Only way I can end the call is to remove bottom cap and take sim card out
This happens on around 50% of all calls and is really bugging me , if its connected to a bluetooth car kit ,the car kit can end it ok
Everytime on bt kit the screen goes off with pressing call
Anyone else having this problem?

Do you have a screen protector? If so it could be one of poor quality and is interfering with your screen. Remove it if you got it. Also it can mess up your ambient light sensor/proximity sensor.

I'm having the same issue too. But i do have it all the time, with every single call i make.
Lets test something here:
Grab a flashlight and turn it on
Cover the light sensor in the upper left with your finger and make sure the 3 capacitive buttons light up.
Uncover them
Now shine the flash light directly into the light sensor
Did the lights turn off? If not get your phone replaced. If they did then you or something is covering the light sensor. The light sensor can turn the screen off at around 1".
I wrote to HTC, they replied after 1-2 hours:
"this is a functional problem caused by a sensor inside the phone" ... "if you can please do get a replacement phone if you have just bought the phone"

For me, the light turned off. In fact I do not need to shine a torchlight. If I cover the top part of the display the 3 capacitive buttons light up. If I uncover, the light disappear. Any ideas? The screen is turning off every time I make a call.
That tests the ambient light sensor(s) - most phones have 2 or 3 - but it doesn't test the proximity sensor... (because the button lights should be tied to the ambient).
Either way, I have not heard of this issue, though HTC has pushed out a firmware update over zune for the Titan recently. I'd recommend to check that, and if there is no update/doesn't fix, then replace the phone.

Is my sensor working properly then? I have a screen protector installed. Is that the problem? I have not tried taking off the protector yet.
You should try that. Some cheap screen protectors can mess with it. I know this was the case with some protectors on the dell venue pro early on.

Fixed the problem. You must remove the clear stock screen protector...it distorts the sensor.
I've been saying that all along
I did a test. Peeled off a bit of the screen protector, enough to expose the sensor. Made a call. The screen didn't blank. So it's the screen protector.
Hi guys I have just recently bought a Radar from bay and im having the same problem, but this time there is no screen protector.
If I cant get a refund form the seller, can I get a warranty repair seeing as though im a second owner?

I just bought SSGS2 last week, and i noticed that when i make a call, this the red light will be blinking/flashing. When I compare it to other SSGS2, all of which will have a red light on when make a phone call (not blinking/flashing).
So I was wondering if anyone had the blinking light?
As far as I am concerned, it does not affect usage just yet.
But who knows...it might be a sign of inferior sensor.
Thank you.

Should it be blinking? or stay on while calling?
Mine is blinking. Those of my friends stay on
can some one please advise, Proximity Sensor should be Blinking/Flashing or solid On when you are on call?
It's blinking for me as well... Why are you guys so paranoid. Is it working? Yes it is.
It blinks extremely quickly, seems like 20 times a second. I can in indoors lighting clearly.

I dont know if this is relevant but I've had both the i9100 and the i9100G. On the G variant the blinking of the proximity sensor was pronounced and noticeable.. whereas on the international variant I've never yet noticed it blinking or staying on. Maybe you have the G variant?

Last question, the top left sensor is flickering a dim red color. Is this normal? It even stays on when I turn off the screen. It's noticeable in the dark. It goes away if I restart the phone. Anyone also have this problem?
Sent from my HTC_Amaze_4G using XDA App
It's the light that emmits if the phone is near your face or far to turn off or on the screen.. you supposed to get that effect when your on call mode and when your not it should turn off automatically..
I think why it kepps blinking because the red light if it is near on your face the red light bounce back to the sensor telling that the phone is on your face thus why the screen turn off..
Well It's blinking when I'm not on a call. It's staying on till I notice it and trun off my phone or restart it.
I do notice if I'm on a call for more than 5 mins I have to hit my power button to get the screen to show up to end a call. Shouldn't the screen com back on once its away from my face? Maybe I have a bad sensor.....

its normal all the phones do that, its the proximity sensor, tells your phone when your face is near the phone so the screen goes off to save battery and also prevent accidental pushing of buttons. If you have in pocket mode checked (always checking to see if its in your pocket to increase the ringtone) in the settings it's probably always on which wastes battery, you could turn in off under settings--> sound.
I swear I saw a post just like this like a month ago.

thats how all phones have been
is this your first smart phone bro?
if u dont cover the sensor it wont shut off
The screen should only turn off when you put it to your face . Once you pull away the phone the screen should wake . Check your settings you shouldn't have to use the power to wake it .

Yea I noticed the same thing. During a call pulled phone away from my face and screen stayed off. I thought something was wrong but if the call is active screen will come back on, if person hangs up and ur not quick to uncover sensor the screen stays off.
do you guys have screen protectors on your phones??? zaggs perhaps??
If anything is "blocking" your sensor, then it assumes that your face is up to the phone. The phone would then only wake up when the call is ended or the power button is pressed.
You must not have ANYTHING covering the sensor
I would say that this is most likely the case
Mine doesnt do that unless I put the phone up to my ear. Normally I just answer the phone and click it to speaker. When I do that the screen stays on....unless my hand/finger happens to be covering the light sensor.
I have Invisible Shield HD. And there's a cutout for the prox. sensor. Have the same problem. Hopefully HTC will fix it on the next firmware update

I'm not so sure about that. My OG Evo has a standard screen protector that "covers" the sensors, and they still work just fine. Maybe those crappy Zagg orange peels will interfere, but I still don't see that being too likely, as they're not really blocking any light.
I have this issue as well and after reading all over for the past two days it appears some units have this issue and some don't. Further complicating the issue is the fact some have screen protectors and some don't. Some have made cutouts on their screen protector and then it works as it should. Very weird.
As soon as I make a call the phone screen goes black while laying on my desk. When the call is over sometimes I can hit the power button to disconnect the call...sometimes I have to hold the power button down 10 seconds to soft reset the phone or I cannot get back to any screen and the call stays connected. Very weird. I got my phone at BB so I am going to stop back and see if they have had any returns and what their thoughts are.

I bought a Zagg and had the issue. They left a hole for a sensor but I think that's the light sensor with the proximity sensor being just to the left and covered. It's a small red light that turns on when making a call. So I made the hole bigger by making it a rectangle uncovering the proximity sensor. Now my phone goes on and off like it should when putting it to my ear. Maybe that'll help some of you? Though I have read some people having the issue without screen protectors.

It looks kinda like a hearing aid or Bluetooth headset icon. But I use neither. I've looked all thru settings trying to figure it out. Checked thru accessibility . Just stumping me, and making me feel REALLY stupid.

I experienced the same issue with the screen turning off as soon as I placed a call. I pulled the Zagg HD off and the issue was resolved. I'm going to best buy today to exchange the Zagg for a new one and I will cut a little notch into it to see if it works.
After the screen goes off you have to press the power button but that little red dot next to the proximity sensor stays on unless you flash a bright light on it. I think regardless the proximity sensor is really sensitive and the Zagg HD just makes it that much more finicky.
Being in a dimly lit area makes it worse too.
**Update**
I went to bestbuy and exchanged my Zagg HD for a new one. I got home notched the cutout for the sensor a little more. Installed it and now I don't have any issues with the screen turning off.

probably the proximity sensor
seen it on my evo lte, dont see it on my new, far superior, sgs3 (sprint), but seems to me that it may be an IR led.
the phone has to send something out to see if it will get it back to measure proximity, whats better than infrared light??
thats my story and im sticking to it
The light that you are noticing is the infrared LED used for the proximity sensor (turning the screen off when placed against your face). This LED likely also helps with facial recognition (for unlocking via the front camera) and eye tracking (keeping the screen on while you are looking at it) as well...as it appears to be on in those times. This is used because infrared light is reflected by your eyes and easy for a camera to pick up.
Hope this answers your question!
God Bless!!!
No it's skynet. Your phone is about to start the machine uprising.
Sorry couldn't resist. Was talking to some friends at lunch about terminator.
I've seen the light as well. Not sure what it is. Samsung has done some tricky things with this phone. Like hiding the nv_data.bin file in a different mount point. My refs got corrupt with me doing nothing but flashing cwm through Odin.
