guys i watched many videos on you tube about poco f1....and in all videos the IR blaster light is clearly shows that it emits torch type light.....but in my poco f1 its just ON the IR sensor in the form of red light....it works fine though..
but can some of u confirm that its a only red light sensor and not torch which illuminates brighter while unlocking....
plzz revert me.....if its a problem then i hv to replace the mine one within 2 days......
Hey, when infrared rays are viewed through a camera, they are white in color. Simple, take another mobile phone, open video camera, watch the ir illumination on the poco f1 , you'll also see that white light.
Is not visible to naked eyes, simillar to the ones you see in conventional IR remotes
Try to capture/see from another phone camera, while you unlock! you can see that Torchlight in your phone too.. Dnt wry much! Just enjoy the Master of the Speed!

so its just a red light when we see it naked eyes...means no torch types illumination is seen by eyes?

I think you're referring to the RGB LED on the front which is the notification light. It means the light can change to practically any color to have different colors for different notifications.
As for the software features that utilize face tracking, I'm sure it uses the front facing camera to do it.
On gsmarena it's listed as a sensor.

thanks for some info, searching in google always ends up with LED, youtube does the same, so may be its related with notification part.

I would be surprised if it were used for something more than just setting the backlight.
At most it handles screen color temperature... I think nothing more.
i guess RGB LED means the LED emits Red Green and Blue light!!
The RGB sensor is the notification led, probably the word "sensor" is a translation errror. and yes R stands for red, G for green and B for blue so you can expect the led can display a rainbow of colors and using the right apps you can adjust the color for each type of notification to your liking.
LOL
You kidding me, aren't you?
nope it is not a typo. check this page out http://imaging.nikon.com/lineup/dslr/d800/features01.htm this is what it says under the part rgb sensor
"Advanced Scene Recognition System with 91K-pixel RGB sensor
Nikon's revolutionary Advanced Scene Recognition System, introduced with the flagship D4 camera, is also employed in the D800/D800E. At its core is a 91K-pixel RGB sensor that meticulously analyzes each scene with the fine resolution. The RGB sensor can recognize your scene's colors and brightness with unprecedented precision, then use that information to implement various automatic controls and give you more natural-looking results. The real breakthrough, however, is that the sensor can detect human faces with startling accuracy when shooting through the optical viewfinder. Along with face detection, detailed scene analysis is utilized to support more accurate autofocus, auto exposure and i-TTL flash exposure results in a diverse range of compositional and lighting situations. The improved subject tracking is most noticeable when using 3D-tracking, which can maintain a focus on moving subjects smaller in size than with previous generations."

Smart Stay uses the front camera
So let me get this straight....
So samsung galaxy s3 uses the front camera's image sensor and then processes that image using the RGB sensor for detecting faces in it for tracking??....All of this process in real time??

The Galaxy S III has an interesting add-on - an RGB ambient light sensor. We've contacted Samsung about it and they say typical ambient light sensors detect only green light (it's the one the human eye is most sensitive to), but they don't work too well under fluorescent lighting. The RGB sensor detects all visible light and supposedly makes better adjustments to the screen brightness.
No no no! It's not the led light! It's not face tracking! It's the light sensor that detects brightness around you then adjusts screen to match! It's one if the best features in samsung phones as most sensors respond to some wavelengths better than others making crappy screen brightness adjustments in fluorescent indoor light but an rgb sensor detects much more accurately the ambient light!
woops, wrong thread

I have the same problem: images from the front camera are too dark. Useless for video chat unless the face is illuminated directly by a strong light source.
Luckily, I don't generally use video chat, so it's not a deal-breaker for me. But still, an annoyance.

Yes, I agree, got my S yesterday, n checked the front camera n the image is blakish until u put light on face.
Its gonna be very difficult for video chatting.
It's strange this is from a natural source of light. And it is a lot better. Maybe it could be something to do with the type of light. I'am glad it is not only me.

The front cam is ok wen it is focussed on natural light even I to face the same problem...
The cam is dark wen I take it to my room for video chat but its absolutely fine when I take it out to sunlight
So it depends on the type of light and the brightness of light
So in short dont worry your tab and cam is ok there is no defect....guess since it is 0.3mp. It dosent have the ability to capture dim light perfectly....

I agree on that, its dim and dark only when inside room, but in natural bright sunlight or where there is more light, it acts normally.
I don't have this problem when video chatting with my friend using QQ, but they are all during day time.

Yeah I'll try to get that and see if it makes a difference.
Here is a picture with the front camera (the dark picture)
And the other is a picture using the back camera (the light picture)
It is not an exaggeration they are both in the same amount of light. The light is artifical light.

It is strange, when I open the camera then click on front camera in the morning when I wake up that time the image quality is great and clear but after sometime till night the camera just dies and blakish pics. Not just during Skype, even while using normal camera app.
Anyone more with this annoying problem? Btw, I am stil on HC 3.2 that came from factory, didn't even update for ps3 controller update.

Hi!
My Galaxy S2 i9100 and my Galaxy Tab 7.7 P6800 has
a built-in infrared LED (look at my attachment).
Is it possible to use this as a remote control for TV, etc.?
Exist an App for that? I can not find the right app.
The App "Smart Cover" uses the Infrared LED to detect
whether cover is closed.
i think it is impracticable because the range of the ir... if you find an app to control the led, you will need to stay so close to the iv receptor to work.
I think the LED is bright enough for a few meters.
It only looks dark in the picture.
It would have to be tested, but I'm not a programmer.

Ehm...
As far as I know there is no IR there unless yours is different (or proximity sensor doubles as IR)
Regards...
The light in my proximity sensor is red, not white. And that too, it's so dim that you can't spot it at all during daytime.. -.-
If you see a red light, it's not IR.
IR can't be seen with the naked eye.

This is wrong! With human eyes looks some powerful IR LED extremely dark red.
It also depends on the wavelength of the infrared LED.
I don't deny that there is a proximity sensor! The fact is, it includes an IR LED.
But the big question is: can you switch the sensor fast enough to send
remote control signals with it ...
And I've tested it with black electrical tape. If you stick the tape on light sensor,
the proximity sensor does not work. The proximity sensor is a combination of
the infrared LED and the light sensor. So you could even use the light sensor
for learning remote control signals.
It's only a matter of feasibility. That could be a very interesting test project.
But I'm no programmer.
This is correct, the IR-LED is from the proximity sensor, most phones use IR-LEDs with 850nm wavelength. These IR-LEDs are not single wavelength (like lasers) they usually bleed into adjacent wavelengths all the way down to 700nm (Red color) that is why some times they can be seen. The IR-LED is directly controlled by the proximity sensor, and in most phones is only active during a call. The only way to control the IRLED would be by accessing the sensor through I2C commands. Also these proximity sensor pulse the IR-LED usually for a few us to up to ms, but the timing control is not very flexible. Android doesnt provide an API to directly control all the prox sensor function so this would have to be done at the driver level.

Hey its me again, I still didnt solve my pervious problem and here is another one!
I have hot pixels on my front camera sensor! I attatched a picture of me hanging out with a friend and you can clearly see the hot lixels EVERYWHERE! It doesnt hapen in indoor shots nor with the back camera. Should I take it back (the phone)?
I am starting to think that I bought a crappy phone I mean it get hot as hell, I have cellular issues, and now the camera? WTF! K should have bought the One X
That's Normal,the front camera have a low resolution sensor.
Use the back camera.

No no no. It cant be a low resolution problem. In lower light conditions, the photos ale less crisp of course, but dont have theese white dots all over them. I think the sensor might be oversensitive to light or something

pretty sure its laser autofocus, mic and maybe light sensor
The light sensor is definitely there, also I think a proximity sensor.
