Already onto my 2nd Hero. Dead pixels et al

Folks,
After complaining to T-mobile UK about the gap at the top of my G2's screen and a couple of dead pixels (see thread: http://forum.xda-developers.com/showthread.php?t=542534) they kindly sent me another within 3 days. Unfortunately though this one has no gap (thanks) there are now 3 noticable dead pixels on the screen (most noticable on startup at t-mobile splash screen).
I just want to know if anyone else has had this problem and get a bead on what others are doing about it. Problem is now I have already had a swap out these guys are now saying the policy is to bring the phone into a t-mobile store and have it sent off to be checked which to me is TOTALLY unreasonable as the handset is supposed to be brand new.. ARRRGGGHH!!! Am I just being REALLY over the top? Should I just have to put up with the dead pixels??

i suppose it really does just depend on how bad they are.
I know you would just be on the edge of HTC's policy on pixels...they usually won't touch anything under four unless they're really obvious

Hmm.. Well there is one which is REALLY noticable during the startup and less so during operation. The other two are not quite as obvious during startup and practically invisible during normal ops. Thing I really want to know is whether or not this is common among users of this phone and they are just living with it as it doesn't really affect the use of the phone or is it just me that this is happening with?

People. If any of you are out there especially if you are on a UK t-mobile contract could you please try switching off your phone then switching it on and check you screen while the splash screen loads and see if you notice any dead pixels or see if you can get a black background and check.
I would be reluctant but prepared to put up with this if it were something which was the norm for the majority of new G2 handsets and really dont want to keep swapping my phone only for the dead pixels to be more noticable on the replacement. I guess it's just a peace of mind in numbers thing.

with current LCD technology, the odd dead pixel here and there is fairly normal, but thankfully not as wide spread as it used to be.
I've not seen any on the ones i have seen, and never had a dead pixel on the HTC built devices i have personally owned (going back to 2003/4), although my one and only PSP, which i bought the day it was released, had a crap load of them and was sold very soon afterwards!
I don't think it is particularly widespread to be honest, but there will always be one or two devices in a run that get a dodgy pixel or two.
have you checked the market to see if there is a pixel conditioning app? I'm sure i saw one somewhere. They don't always work, but it cant hurt to try...sometimes they come unstuck after a while.
oh, and i also have a t-mobile one. None on mine.

Dude.. Fortunately the only guy responding to this post is a guy who is being as helpful as you I can;t say I am even aware that pixel conditioning apps exist.. I'll have a look.

be lucky, i'm actually in a good mood at the moment! i guess it's the prescription painkillers i'm on (legitimately i might add...i'm not some sort of addict) overriding my natural hatred and grumpiness of being at work on a weekend....god bless opiates!
i've already pissed someone here off this morning before they kicked in!!

I bought a sim free Hero from Mobilefun. I'm now on my THIRD Hero due to replacing the last 2. The current one and first didn't have any screen issues but the second one did. As soon as i swithced it on, big bright spots. Sent it back straight away of course, as this is unacceptable.
The current one has a minor cosmetic flaw but I'm keeping it this time
Don't worry about being OTT about this. You pay a lot of money, you want something top notch.
Edit: Incidentally, Mobilefun customer service is the best I've experienced. Both handsets were replaced and in the palm of my hand again within 48 hours!

I have a t-mobile contract hero, I can't see any dead pixels on the splash screen.
There is a tiny gap at the top (ie you can see some copper if you hold it at the right angle to a bright light, but It seems to be the same as all around the rest of the screen and so it doesn't really worry me.

Dude.. As far as the gap in the screen goes there SHOULDN'T be one. I had one on the last handset and changed mine. As I explained this one has some dead pixels but the gap is gone. I repeat it should NOT be there. All manner of dust and debri will eventually get stuck in there and on the underside of the display I am sure. If you can change it I certainly would. I think I will be attempting to change mine again (sigh)

definitely should not be a gap.
my first one does not have one, i'm waiting to see what the state of the second one is when i get home this afternoon. i hope it's ok.

I have a dead pixel as well in the top left corner but it's only noticeable on the startup screen so I don't mind. It's actually quite common with LCDs, my girlfriends iPhone has a couple and I've had phones in the past with some. You can google nearly any phone and find people dead pixels..palm pre, iphone 3gs, blackberry etc. You can return it but then you run the risk of getting a phone with other issues or more dead pixels.

my HTC Hero has 3 dead pixels but they dont bother me at all .

You know i thought i had dead pixels at startup under the hero word, but when i loaded a pixel fixer app to check the dead pixes by cycleing different colours on the screen nothing showed im convinced the start up animation is glitched and makes it look like dead pixels!! get the app and check!!

I have a dead pixel too and mailed to the company from where i bought it. I mean, did pay a lot of money for it, 440€, so i expect a device wich has no dead pixels or gaps at all!! .
Let you know how things go.
cheers

I have 3 dead pixels on the startup screen one in the very top right. I don't notice them when the phone is in normal operation. if I get anymore I will be tempted to send. it back.

Sorry, now back to the topic....
second g2 arrived and no gap or dead pixels on that one either.

Right, I've decided to ring T mobile about replacing my Hero due to the gap. Will it be an issue that it's more than 7 days since I recieved my phone?

T-Mobile will usually try and be funny with anyone requesting the return of a handset after 7 days but just stick to your guns.. The item is faulty but not instantly noticable. If you catch the rigt person you will be ok.. Just try calling back a few times if necessary. I think half the time I get stuff from them I because i hassle them so much.
By the way.. Can anyone recommend a good pixel testing/fixing app??

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.
Sent from my GT-I9300

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)

Nexus 10 defects

Hello guys ! I'm trying to compile a list with all issues found so far in this tablet. My aim is to make a quick-check guide for people, like me, who will buy it from a local retail store and need to know what to look when checking the device in the store in order to avoid returning it later and for all other future buyers. I'm also curious if, statistically, defects are more or less rare than Nexus 7's (I exchanged two before finally giving up and waiting for this tablet).
So, vote in the poll and, if you please, describe the issues you encountered or just add a quick comment.
Thank you
[EDIT]
List of things to check when buying your brand new Nexus 10 :
Backlight bleeding - check it on 100% and 50% brightness on a black screen and see if it's acceptable to you
Dead/stuck pixels - check it in a dark environment, using 100% brightness and solid color backgrounds (use specialized apps like Dead Pixel Check, a ~100kb download)

Well, I I received my Nexus 10 on Friday and rooted it on Saturday morning, bueno now I have to send it back! Nfc does not work and the light sensor works when it wants to

Have you tried something like AndroSensor for the light sensor ? It reads all the sensors from your device and outputs their values. You can check for erratic behaviour with it. How does this defect manifest itself anyway ? Unwarranted changes in backlight intensity ?

After a quick scan of this forum it seems that backlight bleeding is a common problem. So I'll add it to the first post on the quick-check-before-buying-list. Dead pixels could be an issue but the chances of noticing 1 dead pixel on a 300 ppi display are really slim, unless viewing the screen in a dark room with a specialised app ... and having Superman vision.

On my first Google nexus, Google gave to me... 1 dead pixel and some light bleed.
On my second Google nexus, Google gave to me... dust under the screen and worse light bleed.
On my thirds Google nexus, Google gave to me... nasty yellow light bleed and a stuck grey pixel. Oh and the seals were broken on the box, nice..
I've still not had a single return postage label yet either! Right now I have 3 defective Nexus 10's in my living room, wtf!!!!
That's it, nuff's enought, I've asked for a refund this time.
I'll see how they are in a few months when the stores start selling them.
Nice device but im not paying £400 for a defective unit. I really hope they iron out the defects as nothing else tablet wise appeals to me now.

So right now you have 1200 British pounds invested in Nexus and a healthy stock of 3 (not-so-healthy units). Not bad. Anyway, updated info in first post with dead pixels.

Received my nexus 10 two days ago and i think i might be on the same roll as you! I videotaped the unpacking and posted on my blog. Can't post link but you'll find it on the first page if you google search 'seanxz nexus 10'.
I wouldn't be surprised of a massive recall by google in the next few months or so. This is garbage QA!

My nexus box had both seals in tact and I had a couple dust particles trapped under the protective film.

So you suspect that your Nexus has been refurbished or something like that ? It is possible for particles to be trapped when factory applying the protective film. I see that all the time on cheaper chinese LCD products.

The back cover is now creeking, seems like there is a gap of a fraction if a mm. ARGHHHH!!

No, it was completely sealed.
They don't package electronics in clean rooms. ?

[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.

Fix your dead pixel :)

i was really skeptical at first but then i decided to just try this on my old htc evo 3d and it friggin worked :highfive: (took about 40mins though)

You cannot fix a hardware problem with some app. The pixel is dead meaning you can consider it faulty screen. You really believe that app fixes it for real lol? If so alright good for you, but the rest of people that value the money they spent on this phone, I would recommend doing rma if they have dead pixels because they can increase in number as time passes. Do not feel sorry for lg and google. They make bellions. Keep rma till you feel you get a good unit. People pay premium prices and so should be what they get in return.

the only downside to rma with the nexus 5 is google makes you pay for a new phone, get that new phone and ship it back in the box they send you. not everyone has another $450 to drop on another 32gb model nexus 5

I have a stuck pixel that needs to be fixed. I'll run the app for 30 mins and post up the results in a bit

I ran it for an hour and it did not fix it... it did make it less noticeable though

Just ran it twice, 30mins each time but unfortunately it had no effect on the 1 stuck pixel I have. I'll try it with a few other apps and post up results if anything is successful

Hi
Dead or stuck pixels are faulty pixels. Flashing colours does not fix them, it is snake oil.
What usually happens is the process of running these apps for 30 minutes or so just heats up the display and some faulty pixels have connection faults that fix themselves with the stresses caused by expansion due to the heat. It is the same process that means gentle pressure can sometimes "fix" a faulty pixel if the fault is of a certain type on an LCD monitor. Pressure on mobile phones doesn't work as well as the front glass and display is designed not to flex under the pressure of a finger for obvious reasons.
If you are lucky, a pixel that starts working may continue to work, usually however it will just fail again at some point in the future. These faulty pixels that work for a while are the same ones that appear after an hour, a day or a week of using the phone after you thought you had a perfect screen. The fault was always there.
The best thing if you don't want faulty pixels and find them, is not to try and fix them, but to exchange the phone. Better to exchange it sooner rather than later.

Dead or stuck pixels are faulty pixels. Flashing colours does not fix them, it is snake oil.

Than you for this post. I have a very very small dead pixel in the center of my screen and it really doesn't bother me. I have to adjust my eyes and have a white background to see it.. Would this damage the screen further or do you think it would be fine? I don't want to have to get a replacement lol

Just ran it twice, 30mins each time but unfortunately it had no effect on the 1 stuck pixel I have. I'll try it with a few other apps and post up results if anything is successful

Exchange it if it bothers you when you have a dead pixel, as your display should be as good as the money you paid imo

It is very unlikely to become any worse, so if you are okay with it no problem, you do not need to worried about more failing.
Generally LCD displays have an allowable number of dead/stuck pixels anyway. This is because otherwise the yield would be much lower as displays would be thrown out putting the price very high. http://en.wikipedia.org/wiki/Defective_pixel

Thanks!! This helped with 3-4 stuck pixels i had. Eventually i'll do an RMA but for the time being it helped.

Regardless of the allowance, Google will RMA a phone with a single dead pixel, no questions asked.

The OP mistaken "stuck pixel" with "dead pixel"
You can fix stuck pixels..
btw this app is a lot better to detect dead or stuck pixels.

Than app is quite good indeed, but unfortunately it doesn't support yet the full screen...
So it can't be used to detect dead-pixels which are located at the bottom of the screen.
I suggest you using this one, instead, which supports full-screen and can be used to detect dead-pixels and fix stuck-pixels:
search Perfect Pixel Checker on Google Play, because the board doesn't let me post links yet.

Yes it does. It absolutely will render on the entire screen. You just have to touch the screen & the status & nav bars will hide.

FWIW I did something similar to my 6 year old Apple Cinema HD display and it worked wonders ironing out stuck & burned pixels.

ran for over 12 hours and didn't fix any of the stuck pixels on both the devices I received that were faulty. RMA'ed first, and now waiting for replacement for my other one. Hopefully 3rd time is a charm.
