hi,
i know the DHD users have had some problems with the proximity sensors but what i am experiencing is a bit different.
I live in India and i am a Sikh(religion).
i wear a turban(black color) most of the time and my ears are covered by the cloth of the turban.
What i have discovered/noticed is that the proximity sensor does not identifies/responds to the black color. i have confirmed it by putting a black cloth on the proximity sensor while making a call. its does not identify black objects or color.
The proximity sensor works absolutely fine with a naked ear or even if i test it by putting my finger on it during a call. Even the Iphone has the same issue, i checked it to confirm if it was limited to my handset.
i know its a funny situation and its not a problem with the phone. Is there a way to get around this or i have to start wearing other color turbans ( )
waiting for comments and advice
thanks in advance

I noticed it too, when I have a call and I place it in my ear covered with my hair, the proximity sensor does not work but if I place it in my ear without the hair covering it, it works. So, my theory also is, it does not work with black colors.
Black doesn't reflect light hence it doesn't pickup anything. The proximity sensors in phones work via infared reflectence hence using black objects absorb the light making the sensor report no obstruction.
Its not a fault in any way. Phones use ir sensors because they are cheaper than the alternatives

I wear a black beanie most days (it's cold here in Scotland at the moment!) and my proximity sensor still works with no problems. Perhaps the wool the hat is made from is slightly more reflective than other black fabrics?

I was so happy when I saw it! GO NEXUS!
http://hoopload.com/profiles/blogs/nexus-one-spotted-in-the-event
It always is so strange to me when I see someone in person with a Nexus One. You can tell it is immediately but it just shocks you given how rare they are compared to other smartphones.
Hmm, not so sure...
I saw the same episode the other night and thought exactly the same as you. I went as far to rewind and freeze frame it.
It was then that I noticed a slight difference between my Nexus One and the one on the screen. The ear piece has two LED's (one either side). Then I realised it was the Desire as that has indicator lights there. The other reason is the headphone socket is on the other side to ours on the shot as it pans out.
well that kills the rarity then...as the desire is not as rare (no where near as rare) as the Nexus One.
My best friend is on US Cellular and dumped blackberry to go Android(at my prodding) He preferred the Desire over the Samsung Mesmerize(Galaxy S) because of the build quality. Hard to argue with him. He'll love this post.

It's not a Desire. I have one right beside me. Look at the picture - the Desire doesn't have that curvature at the top of the screen.
edit: and the Desire only has one LED as far as I'm aware...
Desire has one LED, same as the N1, possibly one of the sensors being picked up by the camera somehow?
The IR proximity sensor might be picked up as a LED by the camera and turned visible - many cameras "see" some of the IR spectrum, unlike human eyes.
Judging by the picture - it doesn't look like Desire, it can be only Nexus.

I have to agree that it isn't the Desire (just Google Imaged it) and the earpiece os totally different but there are definately two LED looking sections either side of the earpiece grill (ours doesnt have anything similar). The main difference is the headphone socket sits on the left on the unit (ours is on the right) as the guy is holding it, we see the underside of the phone.
What episode is that?
Re: the headphone jack, it could be mirrored?
Bravo for the Nexus actor skills
It was episode 7 (26:10 into it). I had thought that about it being mirrored (used loads in TV and film to suit a camera angle it seems) but in the same shot, the camera housing is square and it doesn't seem to have any LED flash by it either. Also, the volume rocker sits slightly raised from the phone (Nexus One almost flush) and looks lower down the left side of the phone. It could be two phones, one for the screen view and one for the looking up at the "phone in the hand" shot as it looks smaller in the guys hand on the long shot. Not really sure what the little bugger is really...
The sensor shows up as purple... Its a nexus... It just looks weird from the angle/lens just my two cents

Look closer on the both sides of the earpiece, when the phone is in direct strong light that will penetrate the screen tint. You'll see 2 "things" on the left side of the earpiece, and 1 "thing" on the right. The "thing" on the right you know - it's a charging LED, which is visible. The left one your eyes can't see - but cameras see it, as I pointed earlier, and it's a proximity sensor - blinking IR LED with IR receptor which measures reflected light.
If you look at matte (anti-glare) screen protectors, you'll see that some of them have a cut in top left corner - just where the proximity sensor resides.
So "ours doesn't have anything similar" is just untrue.

I've never even seen one in person other than mine!
The only time I've seen one was some lady had one that she got given at some google event, she didn't even know what root was!

I've been seeing N1s on that show too! Almost took a screenshot of one scene where the trackball glows white. Rewound and checked and thought that it could be a reflection of something shiny.
It always makes me chuckle when I see someone put a smartphone up to their ear and the screen stays on; you know they aren't really on a call.
I was sitting in Buffalo Wild Wings playing with my phone when something caught my eye. I'm not sure what it actually is but if you look in the top left corner of your screen you can see a lens and a led and it looks to me as if its a front facing camera but just not activated for whatever reason. Now I don't know if this is on everyones G2 but I really had to look to see it. It does seem kinda strange they would leave off such a hot feature on the top of the line phone.
Yes it's a camera, utilised by the government to keep track of people, but you can't tell anyone. You might want to delete your post before you mysteriously disappear of the face of the earth
Or maybe there's no conspiracy, and it's actually a proximity sensor.
if ur talking about the think near the earpiece im pretty sure thats a light sensor. It measures the level of light to adjust the autobrightness i believe
lol, although a front facing camera is definitely a much wanted feature.
but now that android 2.3 is released, i bet HTC are busy in their kitchens cooking up a new handset to have a dual camera. I'm gutted that they didnt introduce one in the Desire-Z otherwise i'd snapped it up.
Is that a front facing camera? Next to the speaker it seems that there is a camera there yet the US version of this phone claims to have removed it. So what is that thing?
Ambient light sensor and proximity sensor

Ohhh, nice. Thanks for the quick answer.
The carriage for the ffc is in the upper right corner actually. There is a blank space in the frame that one can be installed in, (check the developement thread or search for ffc mod, its possible) its an involved process, where you do get to know your phone very intimately.

they totally couldve put an LED indicator there instead.. i rather have that than an ambient light sensor

When I first got the phone I noticed that thing in the upper left and initially thought it was a LED indicator. I totally agree that it should have been.
Firstly, I'm not describing the same problem as the other camera threads. This is not:
Pink spot
Auto-focus issue
Video FPS issue
Here's my problem:
When taking photos using the main camera on my Galaxy S2, the resulting photo is fine if not using the LED flash. However, if the LED flash is used, there is pink "bleeding" or "banding" emanating from edge of the photo closest to the flash. This is almost like there is some leak of light between the housing of the LED flash and the camera module. This also occurs when taking video.
Apologies if I've missed the thread describing this issue, I've not found one that describes my issue as the main point. The closest I've come is this post, which was in a thread about the pink-spot issue: http://forum.xda-developers.com/showpost.php?p=18743136&postcount=132
I've tried re-flashing my camera firmware OMEF01 using factorytest.apk as someone else in a thread mentioned this worked for them on the assumption that the firmware had become corrupt somehow.
This didn't work, neither did trying the camera firmware update apk that was once found on Samsung Apps.
Example photos attached.
I'm having the same problem and can't find a way to fix this problem! It seems like a hardware problem so I'm taking my phone to samsung service center as soon as I reset binary counter!

This is kind of a stupid suggestion but whatever:
try not holding your fingers near the flash, it will make a reflection and look like that.
If your hand isn't even near the camera or flash and that happens then it's a hardware problem. :/

Hello,
Had my SGS2 for a month now (secondhand) and noticed the pink bleeding too. It only appeared on pictures indeed when using the flash. Since no solution could be found, i took of the back cover (removing the 7 screws and so on, see youtube for that).
My guess was, the lens was catching some flash light from the inner parts of the phone. So i tested the camera without the back cover and this time i could take pictures without pink bleeding.
I examined the layout of the inner parts and did some testing with extra materials to prevent the lens catching light from the flash with the back cover on. Eventually i found that a little piece of black foam adhesive with the length of the camera housing approx 10 mm by approx. 4 mm did it for me. I placed it on the side of the flash led between the lens housing and the led. The 4 mm width of the foam perpendicular on the system board, if that makes sense.
Now when placing the back cover again the protruding foam is squashed a little, making a nice seal between the led and camera housing.
If this solution will last i don't know, but for now i'm one happy flasher.

I've got a problem thats related to this one, but not the same.
I noticed that many (8/10 so far tested) Galaxy S2's have a peculiar slightly pinkish spot in center 40%. It's not very pronounced unless you photograph a white/gray wall or other object of equal color. It's tints objects or features slightly pinker in the center than it does outward, where colors are more spot-on.
It seems to be related to the age of the phones, since all newer models I've been able to test do not display it, yet older ones do. Either through wear & tear, or because older phones use older parts that exhibit this (slight) error. Since I'm a photographer I might be more picky than others with the image quality, and for the majority of people this is a non-issue.
(Sorry for the weird title, couldn't think of a better one)
I recently bought a used Note 3 and after a few days I noticed the notification LED wasn't working. I didn't really mind and forgot about it, until one night I connected the device to the charger and I saw the LED shimmer through between the screen glass and the bezel.
I looked closer at it the next day and noticed that there was simply no hole in the coating like there is for the sensors and front camera. I took the device apart and used a needle to scratch the paint coating away where the LED is and now it looks exactly like it should.
Now I wonder if this is some weird production fault, maybe there are more people who have this problem and maybe didn't even notice their device has a LED (I actually only found out after I saw the LED settings in CM12). If so, I could make a tutorial with pictures on how to do this fix, it's pretty easy and safe.
I don't really get you but going by the title I can say that yes, the Notification LED is covered by a glass, yes. In fact all the sensors are covered by a glass.

This is how the phone should be, there is no hole in the paint/coating. You can only tell the LED is there when it is active

Yes you are right. It seems my phone had the screen glass replaced by a third-party one which uses an opaque paint.
I don't really care since I was able to fix it, but this reminds me once more to be extremely careful when buying used devices, even if they look like new.
Thread can be closed. (I can't do that myself, can I?)
This kinda answers my question lol. I recently bought a replacement screen for my N900W8 and when it arrived I noticed the exact same issue with the LED light so I've been looking to make sure the screen I have will be compatible with my Note. If anyone can help the screen I bought is here.
