Hardware fault

Hi all,
Wished that, for a first post in this forum, I would post something useful. But no, what I'm posting is probably the first user having a screen gone bad.
In the beginning, it happened when the battery went below around 50% and the brightness started going higher and higher to the point where the screen was completely white washed. Recently, the screen went to some kind of green colour taking over the whole screen (see pic attached).
The other phone functions work fine: sound, buttons, happtic feedback. Only the screen decided to die on me.
After multiple FW restores using different versions and only getting worse, I finally decided to call it a day and I will send it to Samsung Belgium for repair.
Hope that I just caught a bad one and that the Super AMOLED technology can survive time.

that is a weird problem, from the first description it sounded like if it got wet and it got damaged by the moisture trapped inside.
but it could simply be a defective screen.
when the screen is off, does it goes back to full BLACK?
or does it stays in that LCD like green/greyish colour?

Phone never went near water or humidity.
Yes, it goes to full black when off and the more it's off, the longer the screen hangs to its original "colours". Well, it used to but now it's worse.

Hi There,
I have problem with the i9000 screen too. Yesterday the screen brigtness suddenly gone up and the main problem is a lot of obvious color banding where things should gradient out smoothly. It looks like it is not having enough color depth, just like lowering your graphic card setting in Windows to 8 bit color or something.
Searching for stock ROM to flash back before I take it for replacement. Don't have much luck with the ROM so far.
Good luck with yours by the way.
Cheers,

It seems that you have the same symptoms that I have.
The only problem I'm having now is that the phone went back to normal after not using it for the last few days. Let's see how Samsung deals with this...

I've had a similar problem and sent it back for repair, as it became permanent after 2 weeks from the time I first noticed it.
Please look at my post here: http://forum.xda-developers.com/showpost.php?p=7652167&postcount=8
and see if it is similar to your issue.
It's now in samsung's lab or something, so in the coming days they should tell me what's the matter with it and how it should be fixed.

Sent mine to Samsung a couple of days ago for repair.
Any news on yours?

So I finally received my phone back from the repair shop and after glancing over the repair report, I came to the conclusion that I had lost the first fight with warranty claims: they did a firmware upgrade !! They upgraded my "old" firmware to a mind-blowing future one: JM2 !!!
After two days, the phone decided to act up again showing the same symptoms as before. In order not to loose the second fight, I decided to go there myself instead of sending it through mail. Being a 45 minutes car hike, I decided first to make sure that the phone was indeed showing the problems initially reported. After some minutes playing with it in front of the desk clerk, he finally admitted that it had to be a hardware problem.
So now the waiting game begins...In the meanwhile, I'm using a Nokia E71 which, while competent enough for my basic needs, it is NOT a Galaxy S. Crap !

To finally close this chapter I received my phone 2 days ago and after a Lcd screen replacement it seems now that the problem is finally solved.

glad to hear everything checked out correctly, I presume everything fell under your warranty?, i got the same outlines around the circle but they are very very faint as I can only see them when i hold the device in direct sunlight at a certain angle so I suppose you're not the only one.

When you say LCD screen are you merely making a mistake or did they actually replace your AMOLED screen with an LCD?
If they actually did that, it doesn't seem like a very good deal...

Just took the Dutch description on the repair report. To my knowledge, Galaxy S phones only come with AMOLED 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.
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)

[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.

does z2 has touch problems?

im now on z1... and i have that problem when touch screen takes life of its on and starts to go around -.-
same thing is on z1s and z2 tablet...
how about z2 the phone?
so far so good?

Any liquid on screen creates this problem for me with th Z2. It does not matter if its moister, sweat or rain drops they make the screen cray cray only way out is to wipe the screen.

Not only..when i chat more than 20 minutes some of my finger touches are not recognized and i must to touch the screen with my other hand to rec.it.. its strange.. .314.. hope Sony will fix it. (hope its not something with the metal frame and sensor confusion).

This is true of every capacitive touch screen I have ever used.

I owned Z2 and Z2 Tab. If you leave so munch oil or finger-print on your screen it will cause touch problem, wipe out and everything is fine.
You may try tempered glass or mate screen protector to reduce this problem.

This is exactly why I never wanted to give up my slide out keyboard phone. I wish more people were like me, I kept holding out for someone to make a respectable keyboard phone but I guess there's no market. I am not a fan of using the touch screen for entering text and numbers. Today was a prime example, my morning was rushed and I am fumbling to try an enter a new hires phone number. So frustrating, I swear it was the 15th try that I finally got it! Here I am fumbling with a phone while trying to direct workers to their tasks and deal with production and management at the same time.

still holding ontu my n900 and n950... my z1 died and got new under warranty... wanna sell it and go for z2 if it doesnt have touch problems like z1...
rocking n950 for now...

yes it does
thats my z2 has ghost touch i dunno what to do to fix it yet

old firmwares seem to bring up alot of ghost touches
i had very little on 314 firmware
also on my older units, i had them regardless of the firmware

I remember back when I had .55 the screen sensitivity was pretty bad, especially during phone calls when it suddenly turns on when it shouldn't, also double tap to wake wasn't as responsive. After upgrading to .314 it seemed to fix those problems

I had this problem with my Z2, too.
Then, after an unlucky drop, my screen was broken, so I got the screen repaired. After approx. a week my screen got more and more its own life. At the end the phone was totally unuseable. The repair shop replaced the screen again, since then it just apperars from time to time like before.
I think Sony has some issues with these screens. My S2 which I had before the Sony had never such issues, even if the screen was quite dirty. Maybe thats why they introduced the Z3 so fast?
Here you can see the "amok screen". I enabled "Show touch" in the developer options.

by the way, just for curiosity, how much have you paid for repair and where have you done it?

Paid for repair 225€ at a shop in Berlin. No official repair shop, in this case it would have been about 350€. However, it is no longer waterproof.
But they replaced the defective (ghost operated) screen without any questions at no cost.

Kinda too much, but then again Sony in Serbia replaced my back cover for 50e, but when I come to think about it, it's probably because the average salary here is around 300e

Screen Burn-In

Wow. I didn't notice until today but the status bar icons and time are showing signs of screen burn-in. I didn't even know this was possible with LCD screens. I can clearly see them with a dark blue full screen wallpaper. This is absolutely horrible.
Check yours too, people!

Not many believe so, but there's no problem getting burn-in on LCD. It's harder than OLED of course. Just look at the commercial LCD screens all over town and you'll see a lot of burn-in's...
The thing im baffeled over is that you managed to get burn-in on your phone. That means you have your screen on A LOT...

Yeah, it's been ten hours guys. My phone's screen has been off for 9.5+ hours during this whole time. I can still see it.
It's also easy to spot when I pull the notification shade down. That's just... Horrible. I bought mine online so sending it for a replacement is out of the question. I can't live without a smartphone for a couple of weeks (minimum time with such grievances).

AFAIK lcd's don't truly get burn in but they persistence which should eventually fade. I'd imagine a defective screen is something acompletely different though.

It's usually ghosting on LCD. It should be reversible. Maybe play some movies or something.

This is kind of concerning and sad to hear. I traded my Nexus 6 for a G4 because I didn't want to deal with burn-in anymore (Moto X 2013 user). I hope I don't ever run into that problem or that the warranty covers it.

Same problem here... I just bought my G4 3 months ago...

i had sadly the same problem and made a tread http://forum.xda-developers.com/g4/help/screenburn-t3152109/post63428991#post63428991
Solved just by sending it back 2 my provider
(i had the device for 2 a 3 weeks) so i got i new one

Got to say, I've had my G4 since May 2015 and have no screen problems.

Just picked up a used LG G4 off Craigslist yesterday, guy had it for a month and was proven from Sprint themselves. Have been noticing screen burn or whatever you want to call it. Can notice it when you pull the notification panel down, and you can see a red tint.
This sucks lol! I'm trying to screen-burn tool off the playstore and will try it for the full 8 hours it says tonight and report back.

Bought my G4 June 05 of 2015. Keep the brightness at a steady 80%. No sign of burn in at all.
It bootlooped to Hell but no burn in.

SAME HERE!!!
It is possible with LCD though , I have SOny Xperia z2 before , but it never have such issue , so when i got my g4 and got this issue at first i thought it was a defective unit. So , i replace a panel under warranty , but then the problem appears again then i realized its the quality of the panel lg used. Lg need to fixed their panel really seriously as it happened since G3 .Now with the LG G5 having the always-on features i believe that the problem would be more serious as with 30 minutes non-stop screen on time with current G4 already appeared such issue, imagine always-on for G5.......

If you turn the phone off can you still see anything? If so it's definitely burn in or something like it. This is news to me, I thought LCDs were immune.

I got sensitive touchscreen problem, ghost touches, burn-in and now bootloop. Now to sent it repair, buy a new smartphone to wait it come back, get it back, see it's still not totally fixed, send it back again. This phone is **** ?
