while we are waiting situation with terrible GPS to be resolved in some way....
does anyone know how rest of GTR sensors are being used. specification says:
BioTrackerTM PPG biological tracking optical sensor, 6-axis acceleration sensor, 3-axis geomagnetic sensor, Air-pressure sensor, Capacity sensor, Ambient light sensor

what are geomagnetic sensor, air-pressure and capacity sensors being used for?
There is an altimeter, and pressure sensor inside that you could check within some menus to check how high and the air pressure.
Geomagnetic is the magnetic North.. compass app will help you here

Someone has a link or something? Does it track your eyes with the camera or is the RGB sensor somehow used? Thanks.

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.

Ah. I see it. I'm pretty certain they're referring to the notification light which is an RGB LED.

No, they don't.

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??
Answer here...

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

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.

IR LED looks on photos white-violett. Test it with your own TV remote control ...

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.

Hello everybody
I'm using an Android 7.0 phone (Huawei P9 Plus) and I'm recording sensor data.
The recordings of the gravity sensor (`Sensor.TYPE_GRAVITY`) show always unreliable accuracy (using `SensorEvent.accuracy`). Is there a possibility to calibrate the gravity sensor?
For the magnetic field sensor (Sensor.TYPE_MAGNETIC_FIELD) I'm getting in the beginning also unreliable accuracy but after moving the phone a bit around it first changes to low accuracy, then to medium accuracy and then to high accuracy. Why is that? Can it not be all the time at high accuracy, also right from the start?
Hi all Amazfit Stratos 2 users,
I think the heart rate sensor on my Amazfit Stratos 2 is not working properly.
When I look on the back, it looks like the sensor as 4 small sensor lights. 2 on top and 2 on the bottom.
On my Stratos, when the heart rate sensor is on at the moment I only get one green light. The readings are vey pour and sometimes during sports it simply doesn't read correctly, it gives me 70bpm when it should be around 140bpm.
So my questions are:
How many green lights does the sensor have?
How many lights should be working?
Is my sensor faulty?
Best regards,
Johnnie
1. Stratos 2 doesn't exist
2. There are two green lights, one at each side
3. Both are one when reading HR
Hello, I saw various cases with a lot of cut outs for pixel 6.
Can anyone tell what is what? A know the primary camera, UW camera and the flash. What the other sensors that is on te camera bump?

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