Well i am very confused whether our phone has a light sensor or not. In the official user manual of I5801 (English-India), at page number 17, its clearly stated that the left one of the two sensors on top left side of our phone is proximity sensor and the right one is light sensor. If there is one, then why is there not any option for automatic brightness? and what its use is? And if its not there, then why is it given in the User's manual ?
Does anyone have any information on this at all? Was/is there any rom that supported automatic brighness via the light sensor?
So why isn't it included in Samsung' Stock Rom ?
Do you think really that no-one ever try to use it .

There is no light sensor on Galaxy I5800/5801. The proximity sensor is actually a pair of sensors, one sends an electromagnetic/Infrared radiation while the other one is to receive it back for the sensor to get activated.

Wow, this is kinda shocking news!
Hi there,
I have the S2 on rogers the 727 series. I have a few issues.
1. LED notifications never worked
2. Camera on my phone is always darker (i compared it with the same from on AT&T and its camera was actually better
3. Whenever i get a txt or missed call the phone never vibrates and i've tried different sms apps and all of them dont work even though the setting is on.
I know there are apps to get LED notifications but i dont like that...i would like to see my LEDs that the phone has working. Anyone have similar issues?

Proximity sensor

proximity and light sensors.....nothing LED there. the only GS2 phone with LEDs is the sprint version....
ahh i see....well what about everyone's camera. Im pretty disappointed with mine when its dark or just not day light the pictures turn out pretty dark. When i use the flash peoples faces turn white.
Go into settings in your camera and turn up the exposure. Indoor shots seem to darken for some reason with the stock settings. See if that fixes the issue.
Hi all
I hope someone can help me solve an issue. I've had a gear s2 for a couple weeks and am pretty happy with it on the device side.
The problem is that when it is bt connected to my Motor X Pure my phone seems to ignore the proximity sensor when I am on a call. The result is that when I raise my phone to my ear the screen doesn't shut off and I end up with all kinds of phantom button pushes from my ear.
I have tested the sensor and it is working when this happens. Moreover when I disconnect from my s2 from my phone the screen shuts off as expected when I raise my phone to my ear.
Has anybody else experienced this issue and does anybody have a fix?
Further, my watch is a t-mobile 3g variant and has not been activated. Would activating it potentially change znything? Finally, my phone is unrooted as I like android pay. But I am willing to root if there is a way of fixing this.
Thanks

I noticed the other night as I was using my pixel 2 and viewing a security camera monitor when it's infra-red/night vision was active that the IR beacon on the front of my phone pulses regularly even when I am not using the front camera of my phone, and don't have a camera app running at the time. Does anyone know why the phone is using the IR light and sensor when I'm not using the phones front camera?
I don't think the pixel 2 has an ir on it.

Are you talking about the notification LED that sits in the top left hand corner or the camera LED flash? Your confusing me with this infrared/IR business. The pixel 2 doesnt have infrared.

No, I am certain it is not the notification LED. That is visible in normal lighting conditions. What I am referring to is only visible in night vision, which uses an infrared light and sensor. So this is clearly a blinking infrared light on the top of the front/face of the phone. I believe it is normally used to detect the distance of subject matter to help adjust the front camera focus depth.
Also, I don't know how the "n" in infrared got deleted after I finished typing in the rest of the title for this post, but I assure you that when I typed the word it showed up as "infrared" not "I frared". And now I can't seem to figure out how to edit the title of the post, so I guess it's stuck like this.
I'm starting to wonder if I've stumbled upon something that may be evidence that the phone is always using the front-facing camera - even when the user isn't using the camera or any app that uses the camera. I had my fiancée also come into the room so I could see if the same happened with her iPhone 6. On hers, no light on the front was active until she unlocked the phone. But as soon as she did, an infrared light on the face of it stayed illuminated *constantly*, whereas the one on my pixel 2 just flashes periodically.
My inner conspiracy theorist is starting to wonder WTF is going on here, and why these sensor arrays are active even when the front camera isn't in use.
I'm hoping a well-informed Android or Pixel 2 developer will see this and respond to address these concerns.

That's interesting. I will try with my phone and nest camera and see if it acts the same on mine.
I just tested it again, holding the phone at varying angles from the security camera, activating and deactivating its night vision/IR mode to see the difference. I recorded a video of it and will post a link tomorrow. When infrared is active, there is a clearly visible blinking light located in the center of the top of the phone just above the speaker bar (the one to the right of the front camera).
I'm really curious to get to the bottom of this so that I can dismiss the paranoia that big brother is constantly watching me through my phone's camera.

Exactly!!
But why is the proximity sensory active all the time? Is it so the Ambient display doesn't turn on when face down?

Its constantly trying to see if your phone is up to your ear or not.
I'm also wondering why the phone would need to have the proximity sensor active when I'm not using Ambient mode, and not currently engaged in a call. There's no need for it to be using the proximity sensor when I'm just browsing my home screen or using some other app. My phone isn't configured to turn off the screen if I set it face down for awhile or anything like that. So there shouldn't be anything using the proximity sensor.
This is common in modern phones, it's checking if you're holding it, if it if is by your face, in your pocket it allows gestures like wave to wake
Get used to it, it's not going away.

But the pixel doesn't have any of those features.
if u want to turn the sensor, disable all option in ambient display.

Nope. I tested that a few months ago (this isn't the first time this has been spotted). You can turn the ambient display off completely and the sensor is still active.
Unless of course they've realised in the meanwhile that this is pointless and fixed it in a software update - I've not retested it recently.

I Just tested my phone, the sensor did not blink at all if u turn off all setting in the ambient Display section. Even double tap to wake will make the sensor blink. I noticed this since 8.0 tho.

It certainly does. I use it to keep the screen off when my phone, in an Otterbox Defender, is in the holster, or when I lay it down face down. Both the front and rear cameras can see into the infrared. Just aim a TV remote at them when any camera app is running and press a button and you'll see the remote's IR LED going. (It has no IR output, though.)
I am using USB Microphone (Samson Go and Blue Yeti) on my smartphone for recording purpose. Both microphones work well on my One Plus 2. However, I am facing problem on recording using these 2 microphones on my Samsung Galaxy S9+. The sound recorded is not smooth where part of the sound is being cut off every few seconds. Need help on this. Anybody knows the solution for this problem?
