So i was playing around with some of the boot anmations on my rooted htc one v and after a reboot i noticed a small dim light on the left side of the "htc" logo on the top under the earspeaker, i assume it's the proximity sensor but i'm not sure if this phone has infrared prox sensor or not, i just need to know whether or not to be worried about this, i have tried rebooting, simulated battery pulls,etc. Any ideas???

Hi guys,
Ill start with saying that my english is veryy bad
But my problem is:
I quess my light sensor on my hd2 is almost defect.
why?
When i start a call (or got an incoming call) the screen turns black
(as its suppose to be when you hold it to your ear)
But it turns black all the time, no matter how i hold it.
So i did a quick test, i called a number, and took a very bright light (100w) just next to the sensor. and after that, it doenst turn black for the first time!
So the sensor isnt working correctly anymore?
It is since my telephone has gone back to the shop for a new screen.
Can i make it better with software? Cause it works.. But only with a very bright light.... Or do i need to get back to the shop?
thnx
try a soft reboot and then if needed a hard reboot/factory reset. don't forget to back up the phone first as it wipes the phone
Sorry, i was forgotten to say:
Ive tried different roms, and even Android. Results are always the same!
That is an odd problem. Especially since the ambient light sensor is not what is used to black out the screen during calls. That would be the proximity sensor.
If you look very carefully just to the left of the speaker at the top of the phone you will see the proximity sensor. Do you have a case on your phone that may be blocking/interfering with this sensor? Do you hold your phone in a way that your fingers or hand may be close to this sensor?
Another thing to try is put the call on speaker phone, this should disable the proximity sensor and keep the screen on. If it does not then you may potentially have a hardware issue.
I haven't got something blocking the sensor. But because my screen was broken, they placed another one. (And since then it happend)
Ok, i did some tests..
I cleaned the screen very proper. And i was sure there was no spat of dust or whatever. so i called again.. And it worked properly!
But.. When i put my finger on the sensor.. (So its not 100% clean anymore) it turns black again. So its veeeeery sensitive..
When i turn on the speaker.. It doesnt turn black..
So conclusion:
It turns back way to fast. Only when the screen is 100% clean, and there is enough light in the room.. It works properly..
Aren't there any settings for windows or android to change the sensitivity? Cause this is very annoying..

Not that I'm aware of. It sounds like they didn't do a proper job of replacing the screen. The ammount of light in the room should have no impact on the screen turning on/off. Also, my screen is often quite filthy and I've never had that trip the proximity sensor. It is possible that the sensor was moved or misaligned during the repair.
Hi, may be it's just my x10i, but last night when I was making phone call in the dark I noticed that the screen is NOT turned off actually by the proximity sensor.
Yes the display went black if you put your finger in front of the sensor. This prevents any mistyping on the phone which is good. However, the back light of the display is still on. By this I mean, the screen is black but it's still bright, which made me feel very strange as it will continue to drain the battery. Anyone else discovered this? Any solutions?
hmm, mine doesnt turn off at all during calls, it will however turn off after 7-8 sec in call.
are you on 1.6 or 2.1?

I've noticed the same on both UK Generic and Global Generic 2.1, the screen goes black but the backlight is still on!!!
Here is a thread covering the same issue, search is your friend. =)

Maybe someone has posted this tip already, anyway here goes.
The light sensor for the home-menu-back-search buttons seems to only kick in mainly in the dark, and off on times in dim lit rooms.
If your phone does the same, put your thumb (i am right handed) over the little HTC logo in the top left of your screen, the sensor seems to be in that location, with the phone on the home screen (unlocked) see if the buttons light up when you do that, mine does.
So, you will get them to come on when needed
I'd love to find a way to do the exact opposite without strapping a flashlight to the top of my phone

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.

Nope I have nothing on the screen its as it came
Have reset device still the same I'm guessing it has a problem , sad to say but HTC aren't impressing me lately even thinking of replacing my sensation with a galaxy nexus soon :-(

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"

Tried this but nothing happens while call is active , I rang someone today got their voicemail I left a message but after my message I couldn't end the call I had to connect it to my car kit and use that to end the call
Time for a new handset here as well I think :-(

What was the outcome. Did the lights turn off?

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.

o.0!? The proximity sensor is normally a led rangefinder in the infrared frequencies. Light sensor could cause lots of false positives...

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?
Cheers
So maybe somebody can help me out. I know the top two sensors on top left of the amaze are proximity and light sensor. Which one is the one on the left of those two?
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?

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.
