As you may kniw, Nexus 5X has a laser distance meter to be used by the camera. I recently noticed that it actually emits IR light. So could it be possible to somehow write an app (or modify an existing one) to use that piece of hardware instead of an actual IR blaster.
For anyone wondering how I found that it emits IR light, I used the traditional method of using a camera pointed to the laser, and I noticed that purple (or whatever color) light

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.

I just got my Verizon G3 2 days ago, I am having a problem with the IR BLASTER, it has a range of about 6 inches...at first I thought it wasnt working at all but then something made me put it right next to the TV sensor and it works, if I am more then 6 inches away from the TV it does not work... anyone else experience this issue and if so is there a fix for it?
No. I have only tried it once since I received the phone on launch day but when I did try it I was an entire room away with no issues
Sent from my VS985 4G using XDA Free mobile app
I've been using the IR blaster daily since I got the phone about a week ago. I can say that it has a very narrow angle (much narrower than a traditional remote control) so it has to be aimed directly at the TV. If it is off by more than a few degrees then the sensor in the TV cannot see the phone's LED. With that said, I can still use it from across the room if the angle is dead on.
One question I have for you (and don't take offense)....are you sure you are aiming the IR blaster at the TV and not the camera's laser autofocus? The IR blaster is on the top of the device while the laser for the autofocus is on the back. At 6" the IR blaster may still work even if not aimed directly which is why I ask.
I will admit, I would prefer if they put the IR blaster on the back instead of the top as I find it clunky to use a touchscreen phone like a remote and point directly at the TV. Would be easier to operate like you would the camera and aim the back of the phone at the TV. The IR LED could also be used in conjunction with the camera for better night vision had they went that route......maybe something LG can think about on their next flagship

no offence taken and yes I am pointing the phone in the right direction, I did see the sensor on the back and thought, maybe that is it but realized it was not, I did more research and found out it is very narrow, I got my case today and it actually seems better with the case on, maybe the little funnel around the sensor shoots it better, I dont know...but it now works about 10 feet away, still too short for me to be happy, my HTC one M7 would work from accross a large room with no problem, didnt even have to point it directly at TV, worked just like a regular remote control. I dont use it often but it is nice to have when I do need it, I did find alot of other complaints on the short range of it, maybe someone will develop a mod to increase its power...
I have the same issue and I checked my ir blaster with a digital camera. I was able to see light from my ir blaster only when I had closed all the lights and i was in complete darkness. Also i noticed that my blaster might be misplaced as the light was not coming out from the centre.
The cameras on the Mate 10 are great, but would definitely benefit with some more tweaking. The primary camera performs really well and offers fine tuned control over almost all the variables. I've found that the auto-exposure in low light raises the ISO quite a bit and the picture ends up looking fake, plastic and grainy. This can easily be fixed by under-exposing or by lowering the ISO in manual mode, but only with the primary camera. The front camera always seems to expose for the face. There are no controls to set exposure or focus, and there is no manual mode. Although it performs well in good light, the results are poor in low light and the lack of any control restricts any creative photography. For instance, if I move the camera off my face, it exposes for the background but it doesn't lock. The exposure switches back the instant I reframe the shot. Is there any workaround for controlling the front camera besides using another camera app?
Front facing camera manual focus
I have the same problem, the front facing camera is almost unusable where there is a lot of light.

I have installed open camera, and this app let me lock the exposure of the front facing camera.
any solution found of this? i can hardly use the front camera because of this issue
The front facing camera on the Mate 10 Pro is great for taking outdoor selfies, as long as you want a solid white background behind you. I can't believe more people aren't complaining about this and that there isn't an official fix.
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.
ok the pixel6 has three cameras. the front camera is self explanatory. but the stock camera app is very lacking in into.
1. what is the picture spec of "medium" photo resolution vs "full"
2. why would i want to switch between the two back cameras and how do i do that?
3. there are 5 things on the back camera block, what are they in order from left to right?
4. what is .7 vs 1x vs 2x? is it optical zoom or digital zoom? and how do they get .7 zoom? shouldn't .7 be 1x and the others adapted .
and no googling for answers did not revel any info.
all anyone seems to want to talk about is the software picture tweaks not the hardware and how you can use it,
I can take pictures of squirrels (Tree rats) with the Google camera app.
And Opossums with the night vision.
Just add, I believe you need to have a Google account to access all of the cameras app features.
Imo, these questions are easily answered by most reviews. Here's a review that tells you a lot about the camera.
pixel 6 specs
1. Medium vs full is going to be the amount of compression used. I don't know why you wouldn't ever use full.
2. You have to switch between cameras if you want different zoom since they use fixed focal length lenses. One is .7x and the other is x1.
3. Left sensor is the 50MP (x1) sensor, next is the x7 sensor, next is the laser auto focus sensor, and then the flash and I believe a microphone is above the flash. Just use your finger to cover one of the cameras if you don't believe me.
4. The main camera is used for x1, that's a 50mp sensor that uses 4->1 binning so it produces 12.5MP images. The .7x is just uses a more zoomed out focal length than the main sensor (lower quality sensor too). x2 is digital zoom on the main x1 sensor.

And if you think that is Kool.
Try using an Endoscope camera with the P6.
It really worked well for me trying to see up inside the dash of a classic car. (86 Monte)
