there is a weird (faint) red light when I'm in a call, anyone know what this is??
(when I take a picture of it using my sensation camera it looks very bright but in real life it is faint like you wouldnt notice it until you look closer)
its there whether screen is on or off, and and if i put my hand over it it just stays lit
is it infrared or something to detect when my ear is near the screen??
My understanding is that is the sensor that tell the phone if your head is next to it or not.
As above, its the proximity sensor for turning the screen off when your face is near the phone.
There are loads of threads on Crackberry about it as their sensor flashes quite noticeably.

Hi Guys.
i bought the Plantronics Pulsar 590a A2DP Bluetooth headset.
and it works great good sound, good connectivity etc.
But.. and its not a small BUT.. the freaking blue blinking light is to strong!.
people look at as if i where some kind of UFO going around with that blue strong blinking light. and this is in the middle of the day.. i cant even express how much its standing out in the dark. looks like some kind of blinking polis helmet.
so to my question. i have talked with Plantronics about this problem and they have no solution. i cant shut down the light using a software hack(button combination) and they cant supply me with some kind of manual to get to the diode to cover up the diode.
Does any of you guys have a solution for this?, i can be the only person that thinks this is annoying to the extent that i render my headphones unusable when used in the public.
No solution from me, but I like to have a look of a photo of the blue light in action
just use a black felt tip pen and color over it should dim it
I've noticed before with blue LEDs - they are so frickin bright - you need sun-glasses to look at them!
Hanmin: yes i think i will post a picture later.
zbee:i thought of using a black felt tip pen. and tried it.. but the ring that blinking blue is of some kind of material so it wont stick.haven't tried this fully yet.. eg different pens etc
i was on the bus yesterday .. and i had to put the cloak over my head so people would stop looking at me.. but. the freaking light finds it way out so it looked like i had some blue halo or something on me.
The red light is possibly even worse. I leave my 590's charging in their cradle overnight. Once I've managed to get to sleep with the thing blinking away in the corner, if I get up in the middle of the night, it feels like I've woken up in a house of ill-repute....the entire room is bathed in a red glow....I just hope that passers-by don't get the wrong idea one day!?!

hahahahha.. yea havent thought of it that way
here is the pictures.. one dark and one light..
as u can see the light is to freaking strong..
I also have this headset, and for me the strong blue light is the only drawback on the entire device, i love all other aspects of it!
(especially now i have different earcushions on it)
I also dimmed the light with a felt pen, a cd-marker to be precise. A tip for when you are applying the pen and you cant quite see what you are doing... put the device on bluetooth discovery-mode so the light flashes blue&red. Now you can see exactly where you need to put more ink
This option only dims the light little bit, if anyone has a better solution, let me know
I also have them. I bought them a long time ago. wow. They are great piece of device. Anyhow, use black tape (electrical tape) and cut them down to the right size. Not perfect but a suggestion.
Being honest, I would look at someone with that headset not for the blue light, but for its size. Everybody will look at you wearing whatever kind of headset that covers your ear. The light just makes them turn earlier. I would use them at home... anyway, watching an evening movie with such a blue blinking may not be the best experience IMHO.
they are not big like a DJ headphones..
anyway.. haven't used them for days now.. just lying around at my desk.
feel like an idiot with that blinking light.. (Beam me up scotty!)

Plantronics LED's are really strong now that you mention it. I also have a Plantronics Voyager 510SL + HS10... and the blue LED is really powerful.. lights up my room.. it has a red LED too and it is also very strong. Everyone gets attracted to that small BT headset just because of that blue blinking light.... but the call quality is awesome. Its worth $500 if anyone going to buy it.
I have a motorola with the same problem, I can understand and find it usefull for the glow when turning the device on and maybe after pressing a button, but is there really a need for them to carry on glowing while lisening to music? Hopefully the manufactors wll get the hint one day....
I wouldn't say they are unusable because of that blinking. This is in my opinion a minor iconvenience for a very good headset. And black tape should easily solve your blue light problem
when set to auto adjust, the brightness goes up when light levels increase. fine.
when light levels are low or darkness, they never seem to dim back to low level.
they only dim back if i switch the screen off/on
do i have fault or is the a feature?
Iv heard if you have a screen cover on teh front it can cause problems. I have the zagg invisible sheild, and dont have a problem with it.
i have the same problem... and i canot find a aplication to set up how much light to give at display for each value it gets from light sensor... something like in windows mobile...the autoadjust is crap it hurts my eyes in a totaly black room
The official HTC screen protectors have holes in them where the sensors are located. There's a light sensor to adjust the screen brightness, and the proximity sensor which turns off the screen when the phone is next to your face on a call. You can't see them by looking at the phone alone, but they're there at the top of the phone screen, near the speaker.

okay.. i looked through the manual when I got the phone and. it says theirs an led to the left of the speakers.. and I'm like no? lol its obviously to the right.. well I called someone on accident tonight and was looking at my phone and a little light lit up to the left of the speaker..anyone know what it's for? lol i is it only calls or what..
seems pretty useless =/ ide rather have a multi colored LED like the evo or evryother phone instead of two red leds lol

I believe those are the camera & light sensors.

Yeah dude those are totally you FFC (front facing camera) and the proximity sensor
Woah wtf CONFIRMED. Seriously just checked and although its very dim, there IS a light on the left corner of the speaker. Its a dark red. I called bull until I tested it. Here's how to see it:
Make a call in the darkest area possible ( the light is very dim) and look directly over the S in SAMSUNG. Interesting!
Edit: ok not an led you're right its the proximity sensor glowing red. If you cover it with your finger, the screen shuts off during a call

the sensors right next to it if look at it in a very well lite environment like outside on a sunny day. the light that glows red is to the right of the sensor

The one that you can see is actually the proximity. The other is the ambient light sensor for the auto brightness. Get over it.

Actually that's not totally correct. The hole directly to the right of the front-facing camera is a photodiode. When a call is in progress it acts as the proximity sensor, and all other times it is the ambient light sensor. To the right of that is an infrared LED - these cast a dim red glow that you can barely see in dim conditions, but if you were to look at it through the lens of a camcorder or digital camera (which are sensitive to infrared light), you will see that it lights up brightly - indicating a large amount of infrared. Skin is very reflective when it comes to infrared. When the infrared light coming out of the LED bounces off your skin and back to the photodiode, the system knows that the phone is against your head and turns the screen off.
Yeah somewhere in the back of my head i knew they likely worked in tandem. Obviously the proximity sensor needs a reciever to pickup the reflected wavelengths. Good info.
Hi,
I noticed that in the upper left corner, near the proximity sensor when I am on a call there is always a red light flashing. So I thought that maybe that is from the proximity sensor alone, but then I remembered as this is not my first device with a proximity sensor that I have never noticed something like this. I also used HTC Desire and never noticed red light near the proximity sensor. I would like to ask you if you all have it also or maybe it's just on my phone.
Thanks
Good question, I am thinking about this from the beginning
Hi all. There are 2 LEDs, but when flashlight is on, only one (on the top) is active. I thought the second one can be activated when camera is used, but no, it does not help. Any ideas on how and when it should be active? Can someone check this on your device so that I can know whether it is a hardware issue with my phone? Thanks in advance!
It seems that's a kind of light sensor, or infrared led - because it even doesn't shine when I apply external 365nm UV light source.
It's the second light sensor which measures light coming from the back side of the phone. When you shine a strong light directly on this sensor, screen brightness bumps up after a while. It doesn't happen if you cover the sensor by finger. The purpose is to have screen readable when you're holding the phone against bright background (window, TV screen...) and in my experience it's quite a nice feature.
