Alright boys and girls
An idea.
We know that there is no Infra-red output on the Note 8, (unlike S6, s7 etc) rendering remote control apps useless.
However, there is an infra-red diode on the front of the note 8 for the iris scanner.
In our house we have infra-red controlled dimmer switches for our lights. Upon messing around having far too much time on my hands, I have managed to get our dimmer switches to respond to the Note 8`s iris scanner LED. Meaning when I have my case open, the lights dim and go up again.
What are the chances of being able to manipulate this LED for a remote app. It seems pretty powerful, dimming our lights from across the room. Can make a vid if anyone wants to see - pretty basic stuff.
Could the LED on the front of the Note 8 be switched (pulsed) fast enough do you think? ie 34khz / 38 khz to enable use as as an IR remote control?
There is obviously an API for accessing the IR diode.
Any thoughts?
Pretty sure it's locked up for security reason.
Samsung obviously say it isnt posible:
http://www.samsung.com/ph/support/skp/faq/1126303
Pd:I also miss the ir emitter from my note 4. It was very usefull for my arduino control proyects
Yes I have seen that. I think Samsung are assuming that it isnt possible as they only provide the API for off and on maybe?
It would involve manipulating the LED at a high rate
After all, all a remote control is, is the light turned on and off really fast (ie 34000 per second / 34 khz) in a set pattern to align with the requirements of the receiver / tuner.
Would need to be rooted obviously with kernel level access.
I may investigate further. Samsung say it isnt possible. That means it must be!
Just read in another post that this isnt possible because the hardware. Ir control remote leds wavelength is tipically 940-950 nm, and IR led for iris scanner is emitting in 810nm. That is why we can see clearly a red dot in the led, I didnt see anything in my note 4 with my eyes (only seen it throught any IR sensible camera). Anyway I will build a simple ir reciver with a PIC when I finish my finals next month in order to check if a IR reciver can get some information with the IR emitter. Hope is the last that we lose hehe

Forget the red dot.
There is actual IR that is completely invisible. Take a photo of your Note 8 from another handset. There is clearly IR in the 900nM range. Use another phone camera, it transverts the IR into visible light.
I do not mean the visible red light you can see when using iris unlock. I do not even have iris unlock / face unlock enabled and it is there.

Hi,
I would like to ask if it has managed to solve somehow. ?
I'm currently tackling the same problem.
Note 8 turns off the remote control of the lights without wanting.
It can not turn off

That invisible ir you are speaking of is part of the proximity sensor.
Just throwing a suggestion, the heartbeat sensor also uses infra red, so we might be able to use that too
This looks really promissing, we have iris LED and heartrate sensor LED, both infrared, this is xda FFS we can do it!
well guys, proximity sensor has an IR LED as well, and almost every phone has a proximity sensor. but still, there's no way to turn all of them into IR remotes till now...

If you havent guessed it yet, I am turning my Kaiser into a spy cam for loafing around in the dark. I have all the stuff, camera (kaiser), IR source (maglite with ir pass filter, check film negatives?), and thats it, but the IR sensitivity, while it does see it, it sucks.
Is there a way to increase the IR sensitivity via software means?

well if exposure has anything to do with it, then that would be a way. however, with the htc camera software we have right now we cant control the exposure, we have to wait til ateksoft releases CoolCamera compatible with the kaiser.
if you do get something to work then let us know, I myself really do enjoy anything that is infrared.
We all know that the nexus one has in the top left hand corner 2 types of sensors:
1. Proximity Sensor
2. Light Sensor
I dont know which one is which but in this demo of the day 2 conference one of them lights up during the demonstration of a call. Can someone explain why that is?
Take a look at timestamp 23:02 in http://www.youtube.com/watch?v=IY3U2GXhz44
That could very well be an infrared light flashing and being picked up on the camera.
Is that how the proximity sensor works? Sends out flashes and looks for a reflection?
Could possibly do that when a call initiates and whenever motion is detected to check the proximity.
Try it yourself. Start a call while looking at your phone through a webcam. I just did and can see it flashing while the call is active. It doesn't flash the same way as on the phone in the demo, but more of a steady flashing on mine. Could be that it is more efficient in FroYo or the version they were running.
Nice find, I overlooked it when I watched it earlier.

Not sure which sensor it is but
1) infra red light does show up when you look at it through a lense with filter/coating/film. Try looking at your tv remote with your digital camera.
2) the blinking could be the video framerate
I think it's most likely the proximity sensor. The light sensor should just take in data and never give out any type of signal. Also I did over look the way a proximity sensor works. It does send out some type of signal and it needs to collect information such as reflection index and velocity to get an accurate measurement of distance
Didn't notice it lol.
Like britoso said:
It looks like infrared sensor. probally the proximity sensor.
Hey guys, I'm fairly new here, but there's something that keeps bothering me.
On the left side of the LG there's this 3(?) LED lights or something..
Does anyone have a clue on how they work, or if they even work?
Well, they are not LEDs, they are sensors. Two of them are obvious, one is proximity sensor and the other one would be light sensor. Don't have a clue about the third though...
I'm secretly hoping the third to be a notification LED of some sort
Thanks though

- Accelerometer sensor
- Proximity sensor
- Gyro sensor
eh, what?
tenchars
@xmoo
That makes no sense. The gyro and accelerometer have no need for visual input, hence highly(!) unlikely that they are what you say they are.
i suspect the first 2 from the left are both proximity sensors, it could be to increase reliability.
the 3rd is the light sensor.
The proximity sensor is based on an IR diode and an IR receiver, just "film" your O2X with a camera and you should see the IR LED flashing.
Thank you guys
Still think they should've put a LED in it though.
Haven't bought a Phillips hue yet, but planning on changing my whole lighting system with Phillips hue. Now I own a Google Home mini, and a Lenovo Smart Display with Google Assistant. Both are connected, but will I be able to turn on the lights with both assistant? I use the Lenovo Smart Display as like a main console in my living room, because the screen just gives so much more features than the home I have. The camera shutter feature is also life-changing. Makes me feel more safe and less paranoid lol. Both are connected, I was wondering if it can connect with both assistant? Has anyone tried?
both are using google assistant which is mainly web based so both should work with your hue lights once they have been paired i have hue with my google home mini and they work like a charm
I'd actually recommend against doing whole house with Hue bulbs. I have them, and after doing a whole house conversion I think that getting smart switches is a much better way to go.

I see applications for both and I do have both. I splurged on a Leviton Z-wave dimmer switch for a couple of lights cause the Hue bulb price for that type of light was a little too rich for my blood. However, the individual bulbs do give me more granular control. For instance, I got a Hue motion sensor and hooked it up to two different lights in two different rooms so they act as night lights. There are uses for both, think it just depends on what you want and where the lights are imo.
Please bear with me, I'm not kidding and this is the weirdest stuff.
I have a nice tv in my living room, but the sound is 'just' a Katana X soundbar that I used to connect to my PC in the past. Recently I noticed something completely bizarre: I was trying to take a cat pic (cat sitting in front of the tv) with my P30P and the volume of the soundbar exploded. After going near-deaf and looking really, really stupid I did some experiments: When I open the camera app and roughly point at the tv / soundbar, the Katana rapidly increases in volume as if I'd press the "Volume Up" button on its remote.
I do NOT need to take a picture. It's enough to just open the camera. Trying to explain this wacky behavior I .. assume that's the auto-focus / depth sensing or something? Just to state the obvious: This is NOT intended and doesn't happen with other handsets (say my gf's Samsung S9).
Questions:
- Is this an issue that came up before, for anyone?
- Is there any reasonable way to report that as a bug to Huawei? As in - a way that's actually reaching them?
TL/DR: My P30P is a 3rd party remote control for my soundbar with only one button, 'Volume+', that is fired constantly as long as the camera app is active....
Maybe when you use the camera application the IR blaster sent signal to your sounbar....
While I've never experienced this before, I can possibly guess why. The Time-of-Flight sensor next to your cameras transmit pulses of infra-red light in order to map out 3D shapes. While the exact wavelength of this signal is designed to be different to most IR remotes, it's possible that your soundbar uses a non-standard IR frequency that matches the ToF transmitter, resulting in it misinterpreting your camera as the volume up command on a remote.
Do you use your IR remote for controlling your soundbar? If not, a temporary measure would be to use opaque black tape to cover the IR receiver on the soundbar.
Thats not a bug! thats a feature!
only if we could control it to use as a IR blaster and universal controler.
