[Q] Infrared on NC ? - Nook Color General

I was wondering what the little round window next to the home button is. It looks like some kind of an infrared sensor ?? You can barely see it, but it is there. It is about 1/8" round.
Any thoughts ?

It is a light sensor, for the auto-brightness feature.

Which sadly doesn't seem to work, hopefully just a kernel module or configuration to fix it.

Light Sensative Back-lighting?

Hey guys, I know that the Kaiser has a light sensor to tell the keyboard when to light up (at least I think I read that somewhere)... So does anyone know a program that uses this light sensor to adjust the backlight of the screen according to how bright it is outside? I would love it so that when I'm indoors the backlight is dimmer to save battery, but when outside in direct sunlight it gets brighter so I can see it well. Anyone know if this is plausible?
If a program doesn't exist, I'd really like to develop one. However, considering I have no experience, I would need considerable help. If someone is interested in developing this, that would be awesome!

I don't think there are any light sensors on the Kaiser.The keyboard just lights up anytime when you want it, I think there is a setting for that.
to the left of the letter q on the qwerty keyboard there is a sensor that makes the keyboard light up when it is dark
If you press a key and it is dark, the keyboard backlight will invoke, and if its light out and you press the keyboard, the backlight does not invoke.
what dyou mean lights out
the backlight will light up whenever the sensor next to the q senses no light

He said when it's light out, as in when there is a lit environment.
Anyone have any ideas how to tap into that sensor? Or perhaps have the lens of the camera sense light when the keyboard is closed somehow for the backlight? Am I thinking way to hard about this? lol
keyboard light sensor
Turning off light sensor for keyboard:
Start/settings/buttons/backlight tab/uncheck "enable keyboard backlight auto sensor". That's it.
Cheers
Keyboard Backlight Time-Out
My backlight comes on fine, but no matter how dark it is, it will not stay on for more than a few seconds. So then I have to hit just ANY old key to try and start typing again.
Anyone know how to make the KEYBOARD backlight stay on longer?
Thanks.

Two lights top left of phone

Sorry if this has already been asked but what are the top two lights in the top left for? must be in bright light to see and maybe a slight tilt
I think one is the light and one the proximity sensor!

I was wondering this too Wasn't too sure to ask lol.
What kind of light is it? I know the led light that is used for the nexus is in the top right..

They aren't lights but sensors. One detects the amount of light in a room to automatically change your brightness, and apparently the other is a proximity sensor, which I didn't know, but makes sense. The proximity sensor is why your screen turns off when you put your phone to your ear during a call.

Need help samsung galaxy s proximity sensor not working

I need help with identifying the problem why my proximity sensor isnt working. This gets annoying because my phone turns the screen off when making a call and you can turn it back on since it thinks something is all the time in front of it. Is it maybe dust? On which side is the sensor located? Is there any software update for a proximity sensor?
If I type in *#*#0588#*#* that runs the proximity sensor test. The screeen goes green, vibrates and stays on 1 all the time( doesnt flick between 1 and 0 if I i move it). What can I do?
I've got a problem with mine aswell. It is always 0 in the test (it can't sense if i put anything over it).
It use to work but suddenly sort of died. I'm not sure what the problem is too but I would like a fix if anyone can come up with one
Funny thing though, my proximity sensor worked fine for 1 call this afternoon, but failed again soon after. :/
Looks like this is one big riddle for the samsung galaxy users. :/
I made a discovery.. If i shone a bright light on my sensor and held it really close to it (like 0.5-1cm away) then the proximity sensor would react and say something is covering it. Only works with a bright light though :/
How bright is that light? May I ask you what are the other 3 values of your sensors?

hmm it was the flash from my digital camera. I think any decent light would work. Try a torch, if that doesn't work try something a bit brighter.
As for the values, which 3 values do u mean?? sorry
Light, magnetic, accelerometer.
Which rom do you have?

oh, the values for accelerometer work fine, the xyz values react as they should when i move the phone.
Light sensor goes as high as 15000 lux when I shine the light on it.
Magnet sensor: 2 and the xyz change and react as they should. same with Azimuth Pitch and Roll.
As for the rom, I'm on darky's 10.1 Extreme Edition
As I thought my light sensor is also faulty. It goes only from 0-22lux
My solution

I don't know if this helps, I had a similar problem.. After i made a call my screen would not auto turn back on for me to disconnect the call.
It may have been coincidence, but after i disconnected "Increase volume in pocket", everything started working properly again.

Sorry, I should had given this information. This happened on a S4 (I9505) android version 4.2.2.
I don't know if this particular phone has the same menus has mine, but its how i solved my problem.
Having this issue too.
Nothing mentioned so far has worked for me.
Galaxy S4 SCH-I545 on VZW running 4.2.2.
Unfortunately I don't know when it started so I can't pinpoint any apps as possible triggers. However I have tried out all sorts of apps status bar apps, active notifications apps, launchers (Apex is my current now)

its normal have bubbles on oled?

hello, I have like 3 days with the device and on a dark with lights environment and can appreciate little bubbles on the display itself, one on top like the photo and a few more on where its the fingerprint scanner, this is normal to a oled display? or its a faulty one?
its very difficult to see the bubbles and more to capture with the camera.
I appreciate your help, thanks
That's the technology underneath. The sensors need to see through the display. Top right ist the brightness sensor.

Question No proximity sensor in s21 ultra ?

I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).
But couldnt find it

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.
adamlee2012 said:
Yes it has one. It's near the light sensor... They are both under the display.

I dont think it has .
Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

I’ve just tested mine during phone call. It’s definitely there… I’ve seen it.

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7

The light sensor is there , itried with cpuz , but i feel the proximity sensor does not work properly .
It wakes up the screen during calls
