Yesterday i bought a HTC Hero (my first one). When i turned it on and toke a good look at the starting screen (the one that says Hero, and HTC), i found a white pixel, probably dead or something. I went back to the store to get a new phone. This was not a problem at all and i got a new Hero. Now again, when i turned on the phone and toke a good look at the black screen, i also found 2 pixels with a other wierd problem:
The pixels also turned out white when i looked at them in a specifica angle. Just to be clear, i am watching on a black screen (starting screen). If you look at the screen and not in a specific angle i cant spot the pixels directly, but when i tilt over the phone slightly they show up and are 2 little white dots.
After i found out i downloaded the Detect Dead Pixel app. This app can create a black screen, the same screen as the home screen. When i use this app to spot the pixels again they are way less visible than on the home screen... I can spot 1 of them a little bit if i look at the screen in a certain angle and i can see a little dot, but i cant see them that good as on the home screen. They are not visible on other colors, only black.
I really dont know what to do with the phone now ... does anyone know what this is? im a bit concerned. Thanks!
After a bit more research on my phone i firugred that the dots really arent that visible. Maybe its just dust under the screen? When i put on a black screen using some kind of Android app i can not spot them. If the pixel is lazy or dead it should be clearly visible on a black screen right? for the lazy one then.
Anyway, i spotted a other problem on a black screen:
A brighter spot on the top part of the screen (like someone is pressing on it a little bit). Is this a problem ? im deciding if i should return the phone again..
Well its entirely upto you mate - i dont know what contract you've taken out but you may have that phone for 2 years. If your not entirely happy with it i'd take it back while you still can.
Issues with the screens rarely correct themselves.
My first Hero had around 10 dead pixels and i got it replaced as i wasn't happy with it. I now have one with a perfect screen and i'm really happy with it!
Well i just returned to the store and got another phone. This is the 3th one, and it still has problems, even more then the previous ones ....
On the boot screen there are about 10 very very tiny white wierd points visible ... im getting a bit frustrated here. What is this with all the screen problems ? :S
looks like they got a bad batch in your shop... have you considered powering up the phone while you are still in the store? might save you same time and way...

I have done that, but as i said, its only really visible in a dark room with screen brightness on 100%. I have checked the phone in the store and it just wasnt visible. When i checked the screen in a complete dark room i spotted the little things again. Looks more like dust to me =\
If your brightness is 100% you should see that one single pixel immediately.
Try making an image in paint (480*320) with a black background and a single white pixel. Open that image on your phone. The dead/lazy pixel should be just as bright as the one you drew.
Also the brighter spot is normal. It's called "backlight bleeding". Every lcd screen has this 'problem'.
They are not clearly visible, i think they are smaller then pixels, but they are countable on the bootup screen. When i tilt the screen them seem to change color (might just be dust). Green etc. I dont know what to think of it, come on. A wrong batch shouldn't be the problem if its dust, then its just a assamblation error. But 3 in a row?
I'm getting a bit pissed
It's dust or a fingerprint blocking a very small subpixel. Can't you just wipe it off? But I suspect very tiny scratches.
idk whether this is possible, but it might be dead subpixels. that would explain why they are smaller than a full pixel...
Does anyone know if that is possible? it sounds like a good explaination. Dead sub pixels could be the problem. They are smaller then pixels, but beg enough to be counted (i can count over 13). Little white dots on a 100% brightness black screen.
It must be dust, its a common question among hero owners. Most of the time the things they see is dust. It would be crazy if all new hero's have up to 10 or 13 dead pixels.
Ok well, here's what happened next:
I returned my phone again, god my cash back, bought a new one at a other store, SAME problem. Swapped it for a new one again, same problem!
Got my money back and i completely changed my mind of buying a Hero.
It is not dust. Its a perfect white dot, and definately some kind of pixel issue.
To bad..
Are you sure you're not being pixel-paranoid?
When reading all of this it sounds mostly like small dust particles under the screen. And looking at the number of phones you have tried, chances are you also got one with a real dead pixel (hot pixel, always on).
But I also think you are obsessed about it. My phone also have one dust thingy somewhere which I found just like you did (pixel tester, black screen). Smaller than pixel and less bright though.
I never notice the thing under normal use, unless I really go searching for it with a black background.
So you might make it bigger than it really is and miss out on a really nice phone.
Then again, we all have our own quality standards and its good yours is a high one!
I have had a tiny dead pizel since I bought my phone. Only really see it on the bootscreen.
I was always more bother by the light you can see coming from under the keys at the bottom and near where the lcd meets the keys.
I also have 3 dead pixels but they aren't that irritating.
I also discovered them when booting up the phone, but for me, they are sea blue (all three)
Maybe it is 2nd hand stuff HTC uses on their phones?
i have about 7 or 8 dead pixels too. it doesn't bother me too much anymore... only notice it in a completly dark room on the boot up screen... probably a common problem with the lcd screen the hero uses
All Hero's have this, or will have it inevitably:
The screen does not connect fully; there is a rubber-border between the glass and the metal frame surrounding the screen.
Look from the right angle, and you can see that there is a small 1/10th mm opening. Dust will come through here, and it will get on the screen.
HTC will wipe it off free of charge of course.
It is NOT a dead pixel; these can be seen from any angle, although the color changes a little but because of the viewing angle.
Call HTC and say you have dust under your screen, they will fix it for you, free of charge.
My wife broke her screen on Friday and we went to a local shop to get the screen fixed yesterday.
This morning she mentioned that she thought the color on the new screen was different. She also pointed out that the buttons at the bottom didn't light up the same.
They practically don't light up at all.
The screen seems a bit dimmer as well. Not as bright and clear.
Is there any way that I can find out what kind of screen they put in her phone short of threatening to bulldoze the shop unless they put the right screen in?
I'm more than capable of dissasembling the phone without killing it and now wish I had but wifey wanted a working phone *today*
Can anyone help out? Are there any part numbers I can use to see what she's got now?
can you take a picture of the phone from upwards, and from sideways (to see if the screen is thicker than it should be)
sounds like it's a regular LCD screen

not without taking it apart first
You can tell if its LCD by how deep the blacks are.

definitely got shafted. you got an LCD screen. i'm pretty sure the local shop orders their parts from eBay or some chinese supplier. those screens are usually LCD even tho some may claim its amoled. the only way to get a genuine Super AMOLED screen is to contact samsung to replace it. i remember reading somewhere than samsung is not distributing their Super AMOLED screens to 3rd parties

I used to be a cellphone technician for a short time and I can tell you that we fixed screens on a lot of touch screen phones... but all the parts are dirt cheap chinese knockoffs!!! There is NO local shop that uses original OEM parts!!! unless u send it back to tmobile or etc!
to answer short and accurate u didnt get the same screen ur vibrant came with!
^$%#
Now I really feel like a total idiot
Two small pinpoints of white light on the screen. Are these dead pixels? Stuck Pixels?
I'm guessing that either way I should exchange it. So, apparently Asus is going to be having quality issues?

let it load
select "fix my screen"
if it doesnt go away after it runs... if it doesnt auto close after a minute, just close it
its a dead pixel
return son!
No dice. Thanks anyway.
Guess this bad boy is going back...
I got a replacement Prime yesterday and thought everything was perfect until I opened my web browser to google, which is pretty much all white and noticed a bright spot like you are describing in the title. Mine are definitely NOT stuck/dead pixels. I know because I returned my first one in part because of stuck pixels. It's almost like these pixel(s) allow slightly more light through than the adjacent pixels. Sort of like light bleed but not at the edge of the screen. I can only see it on white or very, very light backgrounds. It disappears entirely on darker colors.
It is unfortunate but I will not replace this again for a third time. It goes away unless my Prime is charging or docked (which I assume is because it is similar to the tablet being plugged in) and can only be seen on an all white background. I will never use my tablet plugged in, I charge it at night when I sleep, and the limited amount I have it docked is not an issue since it only shows up on an all white background and seems less noticeable than a dead/stuck pixel. Honestly, a smudged screen is more noticeable/annoying. Since I don't use my dock much it will probably end up having a dead battery anyway which means I really wouldn't see it much, unless the battery in the dock is required for it to function while attached, I'm not sure but will find out. Thinking about it I guess it probably does need to be charged for the ports and everything to work unless it leaches off the tablet. Who knows...I'll test it at some point.
It is kind of strange though and I really dislike trying to justify a flaw to keep a $500 device but whatever. IPS screens have some nice benefits but they seem to have a lot of flaws too like bright spots, pretty bad light bleed and more stuck pixels than I am used too. I went back and forth in my OCD head so many times about how many times I would exchange or return this device before I get one that is pristine but if I return it there is nothing else that interests me.
Asus had quality issues with their past Transformer and to think the 1080p tablet will be any different is ignorant.
Anyway, end blog. Since that's what XDA is now
Where did you guys get yours from?

If it's only 2 pixels and they are not directly adjacent, it's unlikely that they will take it back as that is deemed an acceptable tolerance for dead/stuck pixels. I think you need to have 5 or more total or 2 directly adjacent.
Pretty much all manufacturers use this guideline I believe. I hope I am wrong and you do get to exchange it.

I had one dead pixel on my Xoom and Best Buy replaced it without even turning it on to verify
I had two stuck pixels when I first got my Prime. Running pixel fixer apps didn't fix the problem. However, both of them have "unstuck" themselves after a few days of use. If you have some time before you have to return it, you may want to wait a little.
EDIT: Check that. I just ran a dead pixel test and only one of the two unstuck itself. The other one is so unnoticeable to me that I haven't seen it.

Same issue here, bottom right of the screen, small patch of white light in the browser window about an inch from the corner..
Not sure whether to return, the rest of the tablet is awesome!!
I just got another one and about 7 dead pixels the kind you can see on
Black screens and also slightly a bit of light bleed where the headphone jack is

Some time ago I noticed that, in some very special situations, like under direct and strong artificial/sun light and a particular angle, I'm able to see a couple of small, very faint spots, kinda similar to those left by dried moisture (like a drop of water) underneath the screen. At first I though it was my bad for putting on a wet screen protector, but just the other day I had a look at the device of a friend of mine (no protector wahtsoever), and looking closely I found similar spots, just not two but a single and bigger one. This got me a bit puzzled, so I decided to take a look at a third device, this time a demo unit in a shop, and guess what? Also that one had a similar mark right in the middle of the screen.
Now, not that this bothers me much, since you can't actually see it unless you really try (I can't even catch it with a camera), but I'd love to know from you guys if this is a common "flaw" or I just happened to grab a "flawed" handful of devices...
Yup, I have these dark patches. You can see them sometimes if you look at a particular angle when the phone is booting up. I can't see them any other time though
I can see dark patches when the screen is dimmed, especially at night, I can't see it any other times, Nokia returned it to me because they couldn't see it. So they asked to send it in again, it took them ten days to just flash a ROM....I was pissed as it is.
When the Display is off I can sometimes see some "blacker" areas on the screen. According to Nokia These are splices where the glass is somehow glued to the display.
Thank you guys, at least I feel a little better about it now...anyway it still puzzles me how this is the first device I own in years with this kind of issue, and I really had many, both resistive and capacitive, with or without gorilla and even made of plastic. I mean this isn't really a flaw, but knowing it's there annoys me. Damn, maybe I should really just stop being so OCD with my devices, it hurts

I still would class it as a fault, it makes my eyes burn.
Are you speaking about the spots which are visible in the dark if the screen is black?
I saw them when I did my screen black in diagnostics app - lcd test.
So I took a picture of "black" screen with long exposure (iso 400, 30 seconds exposure) and show it in nokia care service. Week after I got new display

Actually those aren't really "spots", it's some sort of light leak that all amoled devices have when displaying plain black: even if all the leds are supposed to be off there's still some electricity going through them. I had that on all of my amoled devices, on my Desire, on my SGS2 and on my Omnia W as well, it doesn't look that great but it's fine I guess. Weird that you still managed to get the screen replaced, maybe your unit actually had some excessive light leak.
Here I'm talking about a different thing, given that you have them you should be able to see those spots I described even with the device completely off if you keep it under a strong light and at the right angle.

Can't reproduce that. I look closely but see nothing special.
Though, as Russian proverb says - the less you know the stronger you sleep
Here is a picture of screen with the spots I was posting about.
So, if anyone have scratched screen as I had, it is a good reason to get repair
PS note that picture was taken with long exposure. Actually my eyes need to get used to darkness to see glow.

Yeah that's it, the good old light leak
Anyway the picture you took being overexposed gives the impression of a huge issue, so I guess they replaced the screen right after looking at that, even tho in normal darkness conditions it's definitely not so annoying. Good for you that you managed to get it replaced anyway
lol a 30 second exposure will bring out the worst of the display. I can understand they replaced it after showing that image that sort of tricks them because it will never be even close to that visible to the naked eye.
Completely normal for AMOLED displays.
Hi guys have you guys ever seen something like this before?
Yeah, happened on my LG G2 and G3 too.
Its when the phone gets hot over multiple times for extended periods this happens and is visible when the phone gets hot. Apparently its the glue between the screen and digitizer (if I remember correctly).
The only fix is to have the screen replaced
I thought it was a LCD defect and not AMOLED, guess I was wrong :-/

I guess I'm just worried theres an element of human error with something like the edge
