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.
Hi,
Today I've noticed a little white spot only visible under white/light colors background.
This picture isn't very clear (it is much more visibile than it seems) but I think it gives an idea.
Any one with the same problem? My phone never fell, doesn't have a single scratch and I always carry it inside the leather case.
Since I bought it through expansys do I have to send it back to them or can I go directly to an official repair center here in Portugal ?
I have the same, in similar(or the same) place. It is just slightly brighter spot.
Also ordered it from Expansys, but I am not going to send it back for replacement now. Do not want to loose my Leo for few weeks, I just love this phone
I have a similar white spot on my screen too. It wasn't present when I bought it. I can't understand what generated it.
I Too
I had the same problem. I bring my phone to service. They replace touch display with new one (I have 2 year warranty ).
I have the same problem. Sent it back to seller and now waiting for almost 4 weeks for repairs.
fortunately i have no that white spot...
Same problem here, sent it direct to HTC and they replaced the screen.
it also happened to me.
i had that problem, the only difference is i know where i got it from. i was sitting on a seat and the phone was put under some pressure and the screen stuck to itself thats the only way i can describe it. then it poped back out and left that strange white mark where it had stuck to itself, so thats a lesson to me (and you) do not under any circumstances have your phone in your pocket when sitting down. i had it repaired under warrenty and every things ok now, i make sure i dont pressure the screen at all now!!
Have a look at this thread (in which there is another as well):
http://forum.xda-developers.com/showthread.php?p=5668097
i had the same problem. just got it back after i brought it in and they replaced the screen. i didn't even begin to try anything myself. now it'd perfect again.
good luck!
cheers, ftrippie
I have a white spot to, right in the middle of the screen, and its the backlight that comes thru a lite more. Nothing that bothers me though since it's not really a defect - unless you don't want it to be, of course.
I sent my HD2 to the service because of the white spot....They told me it will take between 3-10days (I suppose it is the standard response).
Now let's wait....
I had a thread about this too. Very annoying so I emailed HTC and they told me to send it to a service centre for repair.
The problem is that I bought mine on Ebay and after they have the serial number they've told me it was bought in Czech republic so it has to be sent there.
I don't fancy doing that really - what bloody difference does it make which centre it goes to? ALL of these phones are still under warrantee so it shouldn't matter!!
Mine was assembled in Czech republic too but this is happening for all HD2 sold here. I will call Monday to check if they should replace the screen here or they have to send it there.
Today I've got back my HD2 from service after 12days.
They changed the screen and made me a rom update to 1.66.479.2.
Im having the same problem, the CPU is causing it. when you have "overheated" your phone, you can see it. I'm having a very cleary seeable rectangle in the screen. currently im E-mailing with HTC Support for Replacing the screen, or the whole phone!
This is exactly the issue I has, white blurry patches started appearing on my screen, with one in particular very prominent. I re-flashed the network firmware off the memory card, removing the HSPL and returned it to O2 for repair. I got it back 8 days later with a brand new screen.

You clearly have a different issue if you think that.
I had my screen replaced due to this problem & now only 2 months after I have the same problem and getting progressivly worse. Not Happy.
I am lost without my phone, it was hard enough the first time, waiting ages as they didn't have any screens in stock!! nevermind the thought of having to send it off again for a second time!!!
Really bloody annoying but my new screen is starting to develop the same issue. As I said above I had my previous screen replaced because of this a few months back and now I can see some more appearing. I can only assume HTC use bad quality LCDs because I have a 2g iPhone which is nearly 3 years old and it has never suffered with this and hasn't been treated any different than my Leo.
I'm not amused but I will send it back again to be repaired, using sub-standard components will cost them more than me.
White Spot visible on light backgrounds
Same here - refer attached.
Have made background darker to highlight this white spot.
The white spot resembles a 'feathered effect' as opposed to a 'solid spot'.
Red circle shows actual white spot on screen (may not be visible when viewing from a monitor / notebook), hence my attached image with darkened area.
It is only visible on light backgrounds.
Just to mention, I sent in my HD2 to LEAF South Africa yesterday May 13 2010, who completed the repair the same day!!!
LEAF really are superb in South Africa and a credit to HTC.
Thank you Wayne Parkinson of LEAF SA who took care of the details (as always), and their dedicated Support/Repair Team who did the rest.
Beat that HTC Worldwide
My sympathies to those experiencing delays.
Just bring your device to South Africa.
(No wonder the FIFA World Cup was awarded to our neck of the woods!)
I have a similar issue only that its only visible when viewing a bright screen and at a wide angle I see some light spot, its impossible to see it when viewing the screen directly. Can you tell me if it a spot on the screen or below it, or some deffect on the lcd. If its on the surface of the screen how do I safely try to remove it.
My Prime has developed a small bright spot in the center of the screen. It's only visible on white or light pages. I didn't drop the tablet or anything, it just appeared. Anyone else experience this?
EDIT: Here's a link showing a laptop with similar looking spots. The one on my Prime is much smaller than any of these, but it's a similar looking mark. I tried getting a picture of mine, but had trouble doing so.

EDIT2: I've learned that the defect I'm talking about is called "mura," or "clouding."

I have 4 of those spots.. three are within one inch and one of them is at least 3 pixels. I also have poor wifi, so I want to kill two birds with one stone. as soon Asus has a fix for the wifi I will rma..
I have the exact same "brighter" spot at lower center of the screen, don't remember it being there when I first got it... it's very annoying, I think I will send it back for repair.
My friend's first prime had that on his screen (2 white dots) when he bought it only visible on a white screen. He returned it for a new one. Thats why its important to check for those too when you first get your prime and put it through inspection, Just open up the notepad like app, that one has a white screen.
got one too. need to send it back for repair, just been too lazy to do it...
Read somewhere that those are stuck pixels. There's an app in the market that's suppose to fix stuck pixels as well.

I'm 100% certain the spot wasn't there when I first got the tablet, as I did a very close inspection of it. Actually, I was reading through a thread in an iPad forum and there were reports of spots like this showing up on some iPads after a while.

Thanks, but this is different than a stuck pixel, which I also have (I found the stuck pixel when I first got the tablet, but it's so unnoticeable 99% of the time that it doesn't bother me). The link below shows similar looking bright spots on a laptop (the spot I have is much smaller than any of these, but it's the same type of spot).
http://pics.livejournal.com/laptop_mechanic/pic/000p062e
same story here. my prime has 5 bright spots (hot pixel) as well. i did not notice them when i got prime last year. pixel fixer can't fix these either. i can live with these spots though.

I have the same problem, 1 bright pixel just below the home screen indicator.
It doesnt bother me that much, its the only problem i have with my prime and knowing theres lots of people with more problems im not gonna return it for a new one, having the chance to get one worse than i had...
My phone had the same thing when I first received it (still does), but it was my understanding it was a "hot spot" created by adhesive or undue pressure in manufacturing. It's not stuck/dead pixels, in my case at least, and my Prime has no such spots.
I however don't know what would cause something like this over time. Seems to me something in the screen is poorly manufactured and overheating...
Sent mine back and was told by Asus that the white spot is a kind of light bleed that caused by pressure at the area, they will replace the panel for me.
I've noticed that mine has a few white spots similar to who you guys are describing. Mine has two about an inch apart from each other near the lower left-middle of the screen, and another near the right hand side of the screen. I don't notice it when other colours are present, but on a white/light surface, it can get very annoying. I'm thinking I might call ASUS and see if I can get it RMA'd since it has other problems as well. The WiFI is actually pretty ok, but GPS is a total bust. I don't really care about the GPS that much, but it might be what I need to send this in. I'm just worried the white spots will get worse with time.
After reading up on this a little more, the name for the white spots we're talking about is "mura" (google "LCD mura" and you'll get some hits). It looks like it's somewhat common on cheaper displays.
Also have this appearing on mine and also didn't have it before.
I have only noticed it in the last week since I installed the latest update.
I only really notice it on the XDA site.
In my case it's definitely not mura (clouding), but more like pressure spots or pinpoints (usually 2-3 pixels in size.) They are more distinctive in shape than clouding. Either way, sucks for any of us to get these kind of issues. I've actually got an RMA # for mine and will be sending it out either tonight or tomorrow whenever I get a chance.
this can be mura, spots, poinpoints or w/e
i can tell you another one..... so i was working very hard on many several things on my tfp.... sending emails, writing proposals, getting images, working on ideas ect.
I started to get annoyed on how fast the tfp goes to sleep, so i decided to put it to Never. So it never went to sleep and it was awesome because my concentration kept going and i was jumping from my laptop to my tfp back to my laptop ect.
THEN.... i decided to go to sleep and i left my tfp opened connected while it was charging. I completely FORGOT that i had disabled tfp from sleeping. So it sat on the Home screen of my launcher.
When i woke up several hours later, i started to use my tfp and i noticed there was a white area that on every screen it was still there.
It was the outline of the icons! This is the reason why screensavers we're created so this wouldnt happen. This is an excerpt from our trusty wikipedia: (btw, apparently this isnt suppose to happen in lcd's but i assure you it happened to me on my tfp, its not that bad though, as i barely see it sometimes)
Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.
Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity.

So, let me ask you this OP, did you by any chance leave your tfp on for a long time with something on the screen? and the glow that you have now resembles that image/icon/object you had on the tfp?
If that happened to anyone, hit the thanks

Nope. I can say with 100% confidence that I didn't leave anything displayed on the screen that could have caused this. The spot is very small, and is just a little random blotch that doesn't resemble any type of image/icon/object. I've tried taking a picture of it with the camera on my smartphone, but I get those vertical bars that you get when taking a picture of a computer monitor and it's hard to make anything out in the picture as a result. Would using a regular camera allow me to get a good picture? If so, I'll see if I can borrow one and post a pic.
Also, the spot wasn't there when I first got my Prime, and it appeared after about a month.
As of now, I've decided against RMAing it, as (1) I'm afraid of getting back another unit with one of the other myriad of TFP problems, and (2) I don't feel like being without my Prime for 4-6 weeks.

Add 1 to the of people with the pinpoint brightness issue, mine showed up after about a month of use.
I am also waiting to RMA or exchange at BestBuy once he seem to have all of the issues worked out since I have one of the relatively good ones now and don't want a broken one.
dead or stuck pixel
i have almost a half inch bar worth of dead or stuck pixels with more grey tint cloudy looking smugges..on the top portion of my screen..i can only see this when the screen has grey or anything in the grey family. i have not dropped, got it wet, or anythin to it..its been working great for me until about 4 days ago. how and what do i do about getting a rma. i have emailed asus but stilll not heard back..its realy starting to piss me off..this is going to be my 3 one..the other two i was still in my return time at best buy and game stop..this one i am not..any help will be great..would post pics but when i take the pics its hard to see or tell what i am talking about..
Hi all,
Today I dropped my S3...on my bedroom carpet and although there are visibly no cracks or scatches on the surface of the screen when I went to unlock it the touch screen wouldn't work and there is a small black area in the top right hand corner. Just now I tried to see if it would work but found that the colour of my screen has turned to a blue hue
All the buttons are still working fine
The phone is still under warranty so would going the samsung service centre be worth a try?
or would I have to get the screen replaced or something, what are my options?
Any estimates on approx costs too are appreciated!
Thanks
Photos if that helps...sorry for bad lighting x-x

The screen will need to be replaced, take it to samsung. it won't be covered by warranty though
Last night I had no problems with the display, but when I woke up this morning I could barely see anything on the screen due to it being mostly white (like a blur or shadow), and also full of black vertical lines. I haven't dropped or soaked my phone, so I can't think of any reason why this would happen so all of a sudden. I've taken out the battery once, and it seemed to improve a little bit. When the phone is locked and only the black background and the clock is visible I can see a single white line going along the middle, but when I'm using the homescreen it's covered in thin black lines and occasionly colors that look a little like northern lights (I can't find any better way to describe it). Then the screen will occasionally 'white out' and it's impossible to read anything. I've had the phone since March, and haven't had any problems like this previously.
I'm sure the warranty covers this, but I'm hoping there's a way to fix it without sending it in and being without my phone for several weeks. Any suggestions?

Of coarse you dont want to hear it,But I would warranty it The screens have retention problems but I dont think I have heard of one going that bad.
Try to boot to recovery or download mode and see if its the same and or phone off and charging. If so Its a total issue in device.And not just when OS is booted.
