The screen will dim and brighten randomly while i walking or using the phone. Is this an bug or its it my phone sensor spoil? I am using official firmware V10D
the same thing is happening on my phone. help please is very frustrating .
The same thing happens to me and actually it is very frustrating.

I thought that was the Idea of Auto brightness
The screen brighness changes depending on the Ambient light level in your surroundings
You could try cleaning the screen around the top left corner where the Light sensor is and see if that makes any difference
Try to hold over the sensor for >10 sec and see if it still fluctuates. If not, the sensor is fine and the light hitting the sensor is changing, as waynefox writes.
It is also possible to turn off the auto light for the display
Go to settings-->display-->brightness, and un-tick the automatic brightness
ive updated my gtab p1000 to android 2.3.3 and noticed that the ambient light sensor is to sensitive. is there a code like *#*#blah112432432#*#* to control it?
I mean, i want to slow down cus its to sensitive, like - im moving and the display is going crazy ... (and no, i dont want to turn off auto bright) ( i can live with it, just sayn ...)
I wanted to know if I can 'listen' to the fingerprint sensor when the phone's on. Kind of how the Nexus Imprint listens to the sensor when the phone is locked.
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:

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...
Shouldn't ambient display turn off when you cover the proximity sensor. It doesn't work that way on miui 11. How do I get it to work that way
