Yes those are dead pixels and they will exchange the phone no problem, you have quite a few also. You should be happy with a new phone.

Those are actually stuck pixels, not really dead pixels, but since they don't change they're useless and could be considered "dead". But you should get your phone exchanged for a new one as pixel issues in this day and age of display technology should never be seen. I once bought an LCD monitor that had about 15 stuck pixels in about 6 groups of 2 or 3 pixels. The "policy" of the store was not to exchange monitors with less than 20. But I looked at a display model which was 100%, and then opened another box and insisted he check that one and it was 100% too, so I asked him why should I be stuck with a less than 100% monitor? He reluctantly exchanged it and I still have that monitor 5 years later and it's still 100%. Since then I've never had another display (TV, computer, cell) that was less than 100%, so I would complain if even a single pixel was dead/stuck.
For the record, my Nexus S is 100%. My wife's HTC Desire (nee mine) is still 100%, and my daughter's HTC Legend is also 100% still. Don't hesitate or let them bully you - get it exchanged ASAP.

The first thing I do when I get a new phone is check for dead pixels. I can live with a couple on a large monitor or TV, but not on a small screen like a cell phone.

This is a problem! Also, if it has this and it is new, chances are things will get worse along the lifespan of the device. Get it replaced asap.

I will get it replaced tomorrow, I hope they'll accept to exchange it...

Shocking! Think you may have broken a world record. With that amount of dead pixels they cannot argue.

Dead pixels on a samoled screen is not very common. One of the reasons I love the screens. However, I did have one on my last replacement Epic. LCD's like Evo's are more prone to dead pixels and they are pretty common. I had at least one or two in the couple I had.

Dead Pixels.... :-(

So I've had 3 Xoom's now, all have developed dead pixels within 3-4 days of use (the last one had a blotch of about 40 odd dead pixels straight out of the box)..
Anyone else with the MZ601 version having issues like this??
I'm now having to wait a week for my 4th Xoom as Optus do not have swappable stock, and worried I'm going to get yet another one with dead pixels..

Got mine launch day, first 2 had dead pixels and 3rd one had a small speck of dust under the screen. I gave up, stopped noticing it after a few days.. just remembered about it now.

I think I could deal with dust, just not defective LCD panels... Its a shame really, but I guess all of these just go into a pool of manufacturer refurbished units for resale...

Lol. This was day one of the US release that I these problems, heh. Never been so unlucky in my life with dead pixels on "new" screens.

Couldnt find a GS3 without stuck pixels

Hey guys, about 3 weeks ago I bought a Galaxy S3 (after waiting for MONTHS to get one, by the way) at first I was delighted with the performance and looks, but after 3 days I noticed I had a stuck pixel (it was black, on a blue screen) using the *#0*# test
Okay, I got a bit sad and went to the store to get it replaced, and so I did, second one......noticed the same problem some time later
Tried AGAIN, went to the store, this time they let me open as many units as I wanted to , to find a perfect one, I went through SEVEN , ALL OF THEM with stuck pixels in some color (green, red, blue) after more than an hour looking I TOUGHT I found a flawless one.....went home with it to apply a screen protector, while I was doing that I found another stuck pixel, couldnt believe what I was seeing
Went to the store ONE MORE TIME to get ANOTHER replacement, the LAST one.....took it out of the box, and there it was, a black pixel on the green screen, just gave up and got my money back
What the hell is going on with samsung? I just wanted a flawless screen, afte all, its a state of the art device, should be flawless!!!
By the way Im from Brazil and the phones were all unbranded

Might be the imported batch .
Mine is flawless .
jje

Must be the batch, mine is flawless on the LCD test.

No stuck pixels here.

Perfect here too haha. Wait two weeks then go back and try again.

Tested a few and no stuck pixels on any colour background. Bad batch for sure.

Perfect screen here too. Honestly, I have yet to buy a device with dead pixels or similiar flaws, lol. Guess I'm lucky.

Mine is flawless as well - no dead pixels at all. So you waited months? It was released at 29th of May, so in the worst case you waited about 1,5 months.
To be perfectly honest, I don't believe your story...

When I said "waited for months" I meant: I was going to buy the S2, after finding out the S3 was gonna come out I decided to wait, and in my country it was only released at the day I bought it (about 3 weeks ago) so yes, I waited for about 6 months just dreaming about it
If you dont believe me I have one good solution for you:
The big X on the upper right of your screen, click it and witness the magic
For everyone else I hope it was just a bad batch really, for christ sake I loved the device but I cant stand anything but perfection on a US$1000 handheld (its how much it costs here on Brazil)

So you waited months? It was released at 29th of May, so in the worst case you waited about 1,5 months.

He probably waited since it's announcement and possibly even before. But that's pointless to calculate, since one might say I've waited for years to get it... Which btw is true since I knew that more or less the 3.generation would be around roughly at the time my S1's 2year contract was over.
but after 3 days I noticed I had a stuck pixel

I'm very sure you've not found a single Samsung Galaxy i9X00 phone with a stuck pixel and you probably never will. AMOLED screens have no moving parts so the pixels cannot get stuck as with LCD but either die (dead pixel) or react too slow (lazy pixel). Factory-defects such as pixels lighting at the wrong time or shorting with others are of course also possible.
I went through SEVEN , ALL OF THEM with stuck pixels in some color

Have you actually tried apps designed for stuck pixel / dead pixel repair? Often enough the pixel can be revived regardless of whether it's an (O)LED or LCD screen.

My dear friend im sorry for using the wrong expression.....im used to LCD screens and I would call it a stuck pixel because it cant reproduce one especific color (for example the pixel which presents itself black on a blue screen)
Yes, I tried the "unstucking" apps, left them running for hours and hours, like 12 hours at least, it didnt make any difference
Guess I'll just have to wait 2 months and try again, lets hope Im luckier this time, since its not looking to be a general problem...

That was (very faint) humor, so don't take it too personal :silly:
I think everyone understood what you meant, you just used the wrong term for the technology in question
Hmm, that definitively sounds like a bad batch. However I'm surprised, since Samsung's quality control might let one or 2 units slip but ALL of them having defects? I dunno, but that kinda sounds strange...
Maybe your seller got duped into buying units which Samsung's quality control filtered out. Only a hypothesis but well...
On an interested side note: How hard or easy are the dead pixels to spot? Maybe some of us got them but are unable to notice.
The brain is very good at interpolating missing parts of an image or color. Also how bright was it in the room?
I've recently seen a darker splotch on the screen on the red color but can't find it anymore. (Maybe it was just dirt after all...)

Probably a bad batch, I also bought in Brazil and it is perfect.

i had to take my gs3 back to the shop because of a fault with the phone but that was my own fault. but ye the man behind the counter said the gs3 has never had a problem no one has brought one back apart from me to the store so the phones that you went throught must have been fake or something because these are the beat phones out and you dont get any problems with them.

Lets just get one thing straight, a black pixel is considered as a dead pixel, other colours are considered as stuck or bright pixels, it's also normal for a screen to have upto 3-5 pixels problem according to the international standard, so you are luck the shop will allow you get a refund after all the unboxed you did, not that anyone will blame you if you get a dead or stuck pixels in the middle of the screen is quite annoying.
anyway here is my story with problems
1 st unit was a in store inspection, out of the box the power button was stuck.
2nd unit, instore inspection the phone had a few specks of dust in screen.
3rd unit seems fine, and thats the unit I took home until I made and received call, although calls made instore were fine, 99.8% of them, the calls will just cut off between 3 minutes and 7 minutes.
Next day
4th unit had more dust in the screen.
5th unit had a black dead pixel in blue screen.
6th unit with instore inspection seem ok, took this home and then I noticed there was a problem with the wifi.
Phone detects wifi but won't connect, just saves into the memory and sometimes it will connect.
Also my router has 3 ssid set, guest, 5ghz and 2.4ghz, most of the time it will just detect one of the 3 ssid while the other 2 will be detected about 5-7 minutes later.
I also have one of the air drive where i can stream music or video from a portable box, most of the time it won't even connect, but the phone detect the signal, if it connects, it won't stream.
If a wifi signal connects, just moving a meter or two away from the router will disconnect.
In all cases the wifi signal detected is very strong.
Next day
7th unit in store inspection found a dark grey stuck pixel in a dark grey background using pixel testers.
8th unit, the greyish silver side of the phone was made very bad.
Next day did not exchange phones
9th unit one tiny speck of dust right at the top of the right corner of the screen.
10th unit, there were two white spot on the bezel, one next to the ear piece and sensor and the other on the side near the volume, both on top next to the screen.
before I check the 9th and 10th phone I did say I will check 2 more unit and if unlucky I will return it to samsung and have the phone's wifi fixed instead, as I did have a good screen.
Well I took the 9th phone as the 1 speck of dust didn't stand out that much.
upto now the phone is working very well.
there you go, my short story.

It's interesting to see that there seem to be quality control issues with devices sold by Hong-Kong retailer and a brazilian retailer.
Both locations are known to have a lot of fake or "fell of the truck" electronic devices, so I stand by my earlier hypothesis that they might not be devices from a batch Samsung ever intended for sale.
(This does not mean the seller knew about it, any part of the delivery chain can be the cause)

[Q] Screen gap?

I found that my after leaving my Nexus 10 in a case for a day there is now a piece of dust under the screen. I have had this tablet for a few months and I'm 99 percent sure that this wasn't there even a week ago. It sort of looks like a small hair in the middle of the screen, which is the exact reason I exchanged the last one, so I made sure to look this one over several times. Any chance there is a gap between the glass and the display?

Not a chance. The screen is beyond sealed. It had to be there.

I can't quite make it out. Any chance it could be a series of dead pixels?

Also should I send it in to Samsung?

Yes the pixels could have died... Look for a stuck pixel app on the market... But this is very very rare.. I would deffently send it in. There is no reason you should live with that on there considering how much this device cost

The only reason I question sending it back in is due to the iffy samsung repair service. I am also worried I will get a screen with even worse light bleed.

Has anyone got a unit without dead pixels? O.o

I love the phone, but I'm onto my fourth replacement now because they've all had dead pixels. If this next one is still faulty I'll likely give up and settle for it, but I'm very surprised - I've not had this problem with any other manufacturer and it's weird that HTC has this issue.

On my first phone as well. Battery life sucks but screen's pretty good. No dead pixels even though my old GS2 is just as bright.

I went through 3 Dev editions. I got tired of playing this game and cancelled my entire order. Getting a black one from ATT on friday, lets see how this goes. Worst case scenario I take it to a store and they give me one right on the spot. (or get it in from somewhere).

Tested with some app I forget but all good- dev ed.

really don't understand the whole battery life thing, this is the longest last phone I'VE EVER HAD, i've come straight from a sensation where i was charging twice as often as this. I thought it had crashed the other day, every time i checked the phone it said 30%...... for hourrrs.... had to reboot just to check, 30% still lol

I'm on my second One, not a single dead pixel on either. Two completely different screens though.

No dead pixels here m8

On my first and none here either.

I haven't done any tests or anything, but I haven't seen any dead or stuck pixels.

I don't have any dead pixels either. I'm on my second one, neither had dead pixels. Only exchanged due to a weird light coming from the top of the screen, speaker crackling, heavier than usual and a gap in the screen.
My ATT store said they got a new shipment, went in and exchanged and my new One is perfect. =)

Maybe it's a faulty batch in the UK.. After the first 2 faulty ones, I started checking for them on purpose using an app. Oh well, hopefully my next replacement is perfect. I really want to start using this phone.
