So I noticed last night while trying to take a picture in the dark (yeah I know it doesn't work lol) that my screen has close to 75 dead pixels in it. Is this typical of TP2's? None of the three G1's I've gone though had a single dead pixel. In fact, I have not seen a screen with this kind of deadness since the original PSP... Well I'm within my 14 days, so this one is going back to T-Mobile.
I think I may just wait for T-Mo to toss out the HD2, or what ever device they launch that will have the ability to utilize WinMo 7 upon release.
75, tha's a bit much. I have 5 on my tp2 and 2 on my hero. I am probably gonna get the tp2 replaced. They really don't bother me though. I really don't want to get stuck with a refurb
I wish that I had checked my first TP2 for them, but I had to send that one back as the automatic speakerphone didn't work. (Nor did anything that used the rotation sensor, like Need For Speed: Undergroud, obviously sensor version!)
The dead pixels bother me when playing darker games, or looking at darker pics. Also, I just installed a dark theme, and now it looks like there is water dripping down it (in a bad way) lol.
If my next replacement has any more issues, I'm just going to send it back and get out my half broken G1 again. It shouldn't be this hard to do a quality check before shipping.
HTC doesn't recognize dead pixels as something wrong with the unit, except if there's 3 (or more) dead pixels on an area not larger than 1cm^3 (one cubic centimeter). 75 totally is obviously quite alot. ;P
personally i have one dead pixel on my Swedish unbranded TP2, and just one dead pixel isn't really bothering at all, even if it, of course, would've been nicer without it.
What does "taking a picture" and "dead pixels" have to do with each other unless you're talking about the camera itself having dead pixels?
If you want to check the screen for dead pixels find something that displays solid black, white, red, green, blue... There are several "flashlight" programs that do this.

camera lenses cant possibly, not even in a million years, ever have pixels. thats just absurd.
taking a picture in the dark.
in other words, it was an all black screen when he/she:
1- took the photo in the dark
2- saw the dark photo.
that is when he/she noticed the dead pixels.
One dead pixel reporting here
Not a big deal...
I read somewhere about an app to correct this dead pixels
Anyone know more about this?

I think we all know what djinfamousflo really means. The exact technical terms were probably not used correctly but the point is, you really can't come to the conclusion that you have dead pixels based on taking a photo in the dark and then looking at that photo. If that were the case, I would have several dead pixels myself. My photo taken in the dark actually has a couple of pale spots.
If you really want to test, you need to fill your screen with black, blue, green, and red. See if each pixel can display each color. Try it with the pics I've attached.

I don't think you can fix a dead pixel (ie, if your screen is suppose to display white, and the pixel is black, then it's pretty much really dead).
But you may be able to wake up a stuck pixel if you have an app that rapidly continuously flashes red, green and blue.
I noticed them when I took a picture in a no light environment, and proceeded to test with my flashlight app. I'm within T-Mobile's 14 days, so I can get this one replaced, I just wanted to make sure this wasn't a wide spread issue.
Thanks for posts guys
How easy is it to spot a single dead pixel? Does it glare out at you and taunt you everyday, or is it something you rarely notice?
I assume "dead" means it doesn't display anything and "stuck" means it only displays 1 color always.

It's pretty easy to spot if you splash the screen with red, green, blue, and white. Your "dead" and "stuck" definitions are spot on...

Try this. But I couldn't get it to run full screen, so if your stuck pixel is on the top or bottom bars, then it won't work. You can however, slide out your keyboard and force the app to run landscape to cover more ground. But you're out of luck if your stuck pixel is in the corners.

Okay.... So I obviously did not say a lens.
Second, taking pictures in the dark and checking for "dead pixels" is complete and utter nonsense. Flat out nonsense. Again, the ONLY thing that could POSSIBLY find is hot pixels in the camera sensor.

Yes, yes you can. In a low to zero light environment they show up just fine. Camera's don't have pixels. And the camera sensors are digital. They don't work like a screen. Thus when you power on your camera and go into a bathroom you will indeed see DEAD/STUCK pixels. (Assuming your device has any) AND I USED A FLASHLIGHT APP AFTER TO VERIFY. There is a significant difference between a dead pixel, and super low light pixilation that occurs from the CMOS sensor (That's what the camera uses to take a picture.) attempting to raise the light level.
Please if you don't have anything constructive to add, don't add anything at all.
I sent TP2 back for replacement today, and will try out number three. If the third one has issues, well I'll be going back to my G1 personally.
Oh yes - And I never TOOK a picture to find them, I simply noticed this while trying to take a night shot of some pumpkins, thus making the entire screen black. Now if I then took a picture and looked at it, it would show nothing, as the CMOS doesn't have dead pixels. I just NOTICED the dead ones while the screen was all black IN the camera APP.
Maybe that makes it clearer?

I bolded your statement that you really should stick to, although perhaps you should replace "constructive" with "useful".
If you have dead pixels by viewing with a app that shows solid colors, you have stuck pixels. Using the camera in a dark room is not the way to find them.
And digital cameras don't have pixels?? The Tilt 2 has a 3.2MP camera. You can interpolate from there.
To revive a somewhat stagnant thread... if I take pictures on my TP2, there is one all-white pixel that shows up in every picture. Funny thing is it shows only when viewing previously taken pictures, it does not show up in the viewfinder before clicking the shutter.
And no, it's not a dead screen pixel... as I can zoom in on it and move it around.
So looks like a dead CMOS pixel.

View it on your computer; does it still show? Same place every time, again on the PC.
if its on a picture and not permanently on the screen, its not a dead pixel, its noise on the photo. web cams are notorious for little stray off color pixels. i dont think a camera phone is a proper replacement for a real camera. dead pixel and stuck pixel are the same thing. normally flashing black and white on the screen really fast will fix them but thats more for computer monitors. dunno how that would refer to a phone because ive only seen an iphone that had dead pixels, never on any other. if it really bugs you, it is a warranty issue and you can get your phone replaced.
Hi,
I got a grey One X last week and while fairly happy with the phone I thought the notification LED was pretty dim. Unless I look at the phone flat on I can't see it is on. I accepted this was to do with the LED being placed within the speaker grill; however a friend got a White version a few days later and the LED on his is about 3 times brighter.
A few videos I have seen show the Grey phone has a very dim light, would post them but can't link unfortunately.

Has anyone else noticed this or is this an issue with my phone?

I think that is simply because with the white casing, the light is able to shine through the white casing itself. Whereas obviously with the darker casing, it is truly confined to the tiny little hole of the earpiece. I do get the feeling that HTC designed the white one first
Yeah maybe, but comparing the two side by side, it looks as though his LED is a different type entirely. Looking at the LED straight on should negate the case colour and in that scenario his white version is still far brighter.
As long as other people think the grey one is dim there is no reason to send mine back.

It was one of the first things I noticed when I held a grey one. So I don't think it is faulty. But just like most things, LEDs do vary from unit to unit in brightness.
i haven't seen a grey one, but with my 2nd white replacement, the charging led was stupidly dim. now im on the 3rd replacement, the same led is much much brighter. leads me to believe it was positioned incorrectly, or just a crap led.
quality control really sucks atm.
The other day I noticed that my once stock white colored notification LED was acting strangely. It now is multicolored and seems to have a slight flicker when it goes off. I went through Samsung US support steps, removed apps, then full factory reset. Still same problem. I installed Light Flow and tested all colors. Most work but still with a bit of a flicker. White is not working. It displays in three colors, yellow pink and green/blue? I suppose my LED has broken. Has this happened to anyone else? Is there a solution? Samsung US will not support the repair as it is an international GSM phone.
Thank you.

Yeah white isn't really white, its a combination of three colors. Its normal.. no biggie
Well mine is also like that..
Sent from my Galaxy Nexus
I have had my phone since January and it was always a white notification. My old Nexus One was also always a plain white notification. I am pretty sure thats what stock Android intends it to be. The multicolored just started. Either way Light Flow when set to White should display a white notification but it cannot. I am almost certain my LED is defective. Anyone else?

As proved by Newton:
White light is the effect of combining the visible colors of light in suitable proportions (the same present in solar light).

Ok, so... no help here. Thanks anyway, guys.
I sure wish my LED could be fixed. <head down>
Everything you describe is normal.
You probably just never noticed it before.
I actually did notice it and that is why I have posted here. The notification light is supposed to be white. Not multicolored. I know this phone like the back of my hand. The led has changed.
Mine has been like exactly what you've described on both Nexus' that I've owned.

It's a tri-colored LED (red, green, blue).
It displays different colors by mixing those 3 primary colors.
To get white, it mixes all 3.
The 3 LED's aren't close enough together, so around the edges you'll see the individual colors, but in the center it will appear white.
At certain distances/angles/lighting conditions, it can appear almost fully white.
http://www.youtube.com/watch?v=nDrYDjXThLc
If you insist that it was pure white before, then somehow you had a white LED and it has transformed into a RGB LED.
I'm pretty sure no Galaxy Nexus's were shipped with a white LED, and certainly not ones that can transform.
AFAIK
The notification LED at the bottom of the phone has always been a 3 color LED. Red, green and blue. To get white it turns on all 3. Other colors are variations on a theme.
Thank you, terryhau.
My notification light does not look like it does in that video. It is now mostly pink with a green hue no the bottom portion and a purple/blue color in the top left hand portion. It DID NOT used to be like this.
I guess I need to post a pic somehow.
Maybe something like an update or .apk has changed the behavior of the LEDs like reduced the output which would explain why you now see all 3 colors instead of white.

The video shows that it is not pure white, but a mixture of colors. Kind of hard to see because of the bad camera.

Yes. And in the video it shows what my led looked like about three days ago. It no longer displays that way. Now the three colors are glaringly obvious with a bit of a flicker as it fades out.
I am having the same issue. I have a galaxy nexus from sprint and the play store. the sprint one is perfect. all colors requiring a mix of colors show perfectly like pink, magenta, lime etc. However the play one does not. its almost like its off center so with lime you will see a bit of green and then orange on one side. Pink is slightly pink on one section then almost white every where else. Purple is purple and then has a nice section of blue on one edge.
So my question is those who have replaced your screen is the led attached to it or is it part of the speaker daughter board?
My led is darned close to white (accepting Newton's physical laws etc.). I'm thinking that if yours has changed then perhaps it's damaged, but perhaps your rom settings have (been) changed and your notification colour is now set differently (by default). What rom are you using?
I'm using CM9, which nominally allows me to have notifications in different colours for different apps. I find when I pick colours from the chooser, though I'm meant to have complete control over the colour, in reality I can get white, red, blue, green, and different rotations of rainbows.
Clarification: when I say I can get 'red, blue, and green', I mean properly: I get a solid circle of whichever one of those colours I'm aiming for. But anything else (e.g. yellow, orange, cyan, magenta, lilac, etc.) will be a the chosen colour in a small part of the circle, and an array of all the other colours elsewhere in the rest of the circle.
i can get all those colors too... but only on a portion of the window. white will show green, blue and pink on the side.. but not just around the edges. I think this is what the OP was talking about. I honestly do not think its a software issue as i am running lightflow on both of my nexus's and one is has run cm9 and AOKP witht he same results. It has to be a hardware issue. So if any one can answer this, is the LED attached to the screen or the lower speaker daughter board?
Simple question guys: My phone only shows red or green for notifications - is there no orange on this bad boy? I came from G1/Wildfire so I'm used to there being an orange in between...

Well there are two led colors, red and green. I think when both are on orange happens
By default green is set for fully charged/90%+
orange is charging
red is low battery
I can't find an orange option in whatsapp so maybe you can't set orange for notifications. On trying colors other than green or red I still get red.
Orange isn't charging. There is only red and green
Red flashing - low battery
Red solid - charging
Green flashing - notification
Green solid - >90% battery on charge

Hi
It is a bi-colour LED which seems to be an after thought given it sits behind the ear piece grill and on the grey phones is just a tiny point of light you can only see looking head on to the phone.
There are two types of bi-colour LED, one has 2 connections, the other has 3. A bi-colour LED with 3 pins allows both LEDs to be lit independently, giving Red, Green and Red + Green for Orange. A 2 pin LED will light Red when the current flows one way, and Green when it flows the other, meaning you can only have Green or Red and no mixture. Given there is no orange in use now I suspect the LED is a simple 2 pin affair, so there will be no way it can ever display Orange.
Regards
Phil

Your LED has the same problem that my two returned grey ones had - the white model I have has a far more visible LED - I can see it clearly from a distance and also when it's at a near 90 degree angle.

That is because the white plastic allows more light through, but I don't want a white phone as it isn't my preference so I'm living with it, it isn't that big a deal for me personally, certainly not enough for me to sacrifice my preference for the grey phone.

I guess that makes sense - what a bad design flaw as the dark model just lights up the size of the tiny pinhole and the white one creates a light around the size of a circle drawn around four of the pinholes. If I'm spending over £400 I'd rather have one that I can see the notifications so glad my replacement is going to be a white one. Hopefully the wifi on this one will be ok.

I have a black model and mine is silimilar to what the other members white phone. I can see it at different angles and from a distance and in a darkened area it's bright with a quarter inch halo around it.
My black one doesn't show much light, just a pin prick. It's bright enough to be seen as long as it's not in sunlight though.
My Sensation's LED was easier to see, i dunno if it was a bigger LED, or the silver grille just allowed more through.

Orange - Charging
I'm now on my 3rd unlocked European One X for one reason or another - the white one's LED was just right - I could clearly see from a distance if it was charging or flashing. The two grey ones I've had both had barely visible LEDs, which I can't see when the phone isn't right in front of me or when it's at an angle. Is this a problem with some of the phones in gereral or is it just an issue with the grey model? Cheers.
Your 2 grey phones may have been defective, but in general white surfaces reflect more light than black/grey surfaces. This could have made it appear as though the lights were of differing brightnesses, or just that the white phone reflects more of the led's light.

My grey one is just the same regarding the LED, it's a pixel sized flash as it is shining through one of the "precision" drilled ear speaker holes, so you have to be almost looking directly down on it to see it, certainly in normal lighting conditions.
I expect the white is just a bit more translucent so you see a bigger area of light.
It is one of those silly design decisions that HTC seem to make sometimes! The LED should be behind the glass at the top right where the border is, in the same way the other sits the light sensor. I've always assumed it was last minute rushed job to add an LED, and as after thought they just had to place it where they could that didn't mean reworking the phones design.
Some phones don't have LEDs at all. I'm not sure why a notification LED has fallen out of fashion, I find it really useful, for example I leave my desk to make a drink or see someone or for a comfort break, then arrive back to my desk, a quick look down at my phone I know nothing arrived while I was away and it saves turning the screen on to check.

It must be a defect which happens to be on the 2 grey phones then because the difference is huge - one is barely visible and the other I can easily see from across the room (it's probably 30 or so times brighter). Hopefully my 4th One X, which is on its way, will be ok (the white one with the good LED has the wifi problem so that's going back).
