Epic Display Freak Out - Any Others Experience This?

I had only owned my Epic a week and this is what happened to the screen! I thought I was seeing things at first, then it got BAD. My wife captured this short video with her Evo before I took it in and traded it for a new unit.
I'm keeping my fingers crossed. I'm almost 2 weeks into my replacement unit and everything's fine so far.

That screen seems faulty to me.
Edit:
Or maybe even a loose wire?

Looks like a connector to the screen may have been loose :/..

I had it happen. Took it back and exchanged it even though after rebooting it appeared fine. I believe it was an overheating graphics processor (I've had similar happen on a computer).

At first, the guy at Best Buy was hesitant to replace it. I told him I didn't mind if he did a hard reset on it so he could rule out a software conflict (personally, I was confident it was hardware-related). Less than 3 minutes after being reset it was doing it again.
Now, I'll probably root it have some real fun!

I am having that issue right now! Anytime I even slide the keyboard out a little bit, my colors go all sorry and my wallpaper looks like old PC's with 256 colors! Lol or safe mode! I am 5 months into this phone, but hopefully it's still covered under some kind of warranty so I don't have to turn it on an insurance claim. Lol.

Wow! Seems to be a manufacturing defect in the latest round of shipments... Hope getting it swapped with a replacement was simple. Too much money to lay out to start with a defective unit like that, but as with anything, sh*t happens...just not cool when it happens to you!

With the amount of phones sold there are going to occasionally be defective ones.

I've had a similar issue, except much more subtle. Best way I can describe it: There will be random changing horizontal color bars that overlay on top of what is on the screen at about 90% transparency. It looks like something is interfering with the video output to the AMOLED. This only happens when the phone appears to be processing something like the loading screen for the Android Market or during the melody test in the *#0*# menu. It also appears to be related somehow to the battery charge level. The lower the charge, the more the effect. I'm just noting this issue here, and kind of wondering if anyone else has this issue. It doesn't really bother me at all, to be honest.

Getting it swapped was simple & quick once the Best Buy Mobile rep hard reset the unit and saw that the problem continued. As I said in the OP, my replacement is doing great so far.

I think I was having the same problem.
It only seemed to happen when the battery was nearly depleted, and even then only when the screen was on high brightness and displaying nearly all white.
Seems to me like at low charge levels the battery can't supply enough power to keep most of the pixels white at high brightness, so it starts getting distorted.

Go to sprint service and repair store and open a ticket. They will either charge you $35 or it will be free if you're under tep, so long that you have no liquid on the device and it's not rooted. I'm a tech at one of the stores.

[i9023] SLCD screen bends under glass -> yellow stain

last night i was surfing some pages, when i noticed a yellow stain/spot at the right side, near to the top of my screen.
this morning when i looked at it again, i frist thought it was gone, but after some usage, it came back.
taking a closer look, i saw, that the slcd foil(?) under the glass has bend a little bit, what seems to be the reason for this yellow stain. i think it might be a heat problem, since it was gone this morning, but came back after some usage.
i also think it might have to do with using navigation, since my nexus really gets hot while using that.
anyway i will bring it to the shop, but i'd like to know if there were others experiencing this..
here two pics attached (the stain can't be seen that good on a picture).

You sure it wasn't dropped?

yeah, in all those 6 months, that i have it, i never dropped it.

I've also 2 yellow stains,on the left and the right of the lcd on my slcd i9023.I guess it has something to do with heat,because in winter when I've bought it ,it was ok,now in summer the yellow stains appeared.Next week I;ll send the phone to Vodafone service in my country,and I hope it will be exchanged.
Best Regards

That sucks. I hate dealing with hardware issues. Good luck getting it fixed.

After 1 week in service,today I've received back my Nexus S i9023 with a new slcd fitted.No more yellow staints,I hope it will remain the same a few month at least.
Cheers

hello, I am also having the same problem, the same yellow stain has appeared on my right side but i don't have the "warped" lcd as in the first photo... It is definitively a heat problem because i noticed the "stain" when i was downloading on wifi while plugged in and that part of the screen was far hotter then the rest of the screen...maybe some chip under it running hot.
The thing is i got the phone new 6 months ago from ebay so no warranty and my concern is, what guarantee do i have that after i change the screen, that the problem won't appear again? Does anybody know if there is a fix eighter for the screen now or something to prevent it from happening again to my new screen? Could it be a manufacturing problem of the screen itself?
It doesn't seem that this issue is common..Also does the spot spread?
Thanks for taking the patience to read and for any answers.

Today I noticed the exact same problem in the same part of the screen, and I also noticed the foil being bent at that part of the screen. Its perfectly visible under a certain light angle. Being on the exact same spot as your problem, I suppose that it is some chip under that part of the screen causing the problem. I think I also has to do with the fact that the screen is curved... anyway, I cannot return mine for a new one, I hope people in the local service shops will be able to provide me with a fix. Too bad that such a cool phone like the Nexus S suffers from so much problems (I also had the proximity sensor problem that caused screen to remain black sometimes when the phone rings without a way to see who is calling). I will go for one of the new nokia handsets.

Another one here with the same problem on the upper right corner...
I have the phone 8 months now and I am sure that yellow stain wasn't there from the beggining but now it's quite visible especially with white font for ex. when browsing... Also in a specific angle the foil of the screen in that place is visible too...

Same problem on the right corner on top. If its in guarantee they will fix it for free?

now after having my display fixed last october for free, since it's a known issue, i actually got a new stain after a couple of months..
but this time, it's on the left side and much bigger.. time to send it in again, warranty till next february..

I have the same issue, I am planning on getting it fixed as well. Good to know that it's a known issue and it's covered.

Same here, upper left corner...
Disappointed to read replacement parts are defective too...

exactly the same issue on right top corner, I sent my phone to warranty repair currently...

Top left corner here. Just hope i can find my warranty or else Im screwed..

Unfortunately i have just seen the same thing that's happened on our nexus s on my friends galaxy nexus.. i was planning to get one after my nexus s developed the spot but now i'm not so sure anymore..

Center left... the same problem!

upper right corner here. Noticed it in some very hot days that are passing now in my country. should I send it to warranty?
My worries, I got the phone in a promotion (huge discount) afraid that if I returned it they will give my money back and I can't get any similar phone for the same money (I really like/need this device)... in the other hand, it might get worse than it is and unusable

Are you guys running custom kernels?

Nope

samsung build quality , same old same old

Well i have to say i really liked this phone its ui is butter smooth and the screen is super nice, however after recieving my second replacement this morning i cant help but feel this phone is plauged with build quality issues. Both phones had yellow tint same degree purple spot is real bad on replacement phone and it seems to have some crazy banding I also found a small transparant circle in the middle of the screen like burn or something.
Going to try a third and prey I get a working one , but im already thinking i should swap to sensation as i dont want to be swapping phones looking for that perfect one, shame becouse for me this phone dumps on sensation however the build quality at samsung really lets things down.
first build was korea finished china 08.11
second build was korea finished china 06.11

Sorry to hear that, I'm so lucky when it comes to Android devices I often forget that people get lemons.

My story
Hi there,
I bought the SGSII about 4 months ago. It didn't have the yellow tint, but i noticed (after reading a thread here) that the left side of the screen was darker than the right side. So, since i was on the DOA warranty, i decided to get my replacement.
After opening the 2nd device in front of the store's service team, we noticed the same issue. I thought "well ok, i 'll replace that one too." That's when my trouble started. Service team calls the store's manager, he arrives 30 mins later, and we head to his office. He calls samsung's service here in Greece asking if they heard any similar issues from other costumers, then he passes the phone to me. I was told that this issue isn't supposed to exist, and that he (as samsung) had to replace the phone for me a 2nd time.
I walk towards the phone department of the store, and to my surprise the employee there, told me that he didn't want to open his whole stock just for one client, if this issue keeps appearing. So in good faith, i decided to send it to samsung via the store, so they can replace it for me. I was told that this would take 7-8 days.
So, 1 month and 12 days later, after constant calling at samsung to check what happened, the device returned. Their reply till one hour before i receive it was "the phone is still under inspection". Probably an automated response, since there is no possibility that the phone traveled 504 km in 1 hour, and no it didn't arrive by plane. It took 12 days out of 42 just to reach samsung.
The phone arrived in a plastic bag, like the ones you keep food in the fridge. The case was still at the store. As a result, screen had a scratch on it. The best part was their inspection result. "We didn't notice any issues with the screen, but we did a full wipe on your device, just in case".
At this point i started entering rage mode. Not only i had in my hands written diagnosis from the store technicians that can see the issue, also i had a brand new scratch on my screen. The store's manager went defensive, and stated that if samsung's official response was that there is no issue, then there isn't one. No comment on that. (Note: i refused to sign the document that mentioned i received the device back from service)
At this point the store technicians kicked in. If it wasn't for those guys, i 'd still have a faulty device on my hands. After a whole day of making calls to samsung, the techs tried to explain to them that you don't have to be a technician to see a faulty screen. Yet all the replies they got where in the lines of "There is no issue, all SGS II are like that, its the screen's technology, and they shouldn't replace any of the phones" Exactly the opposite of what i was told.
So i decided to take one last action, to see if i could get my money back. I wrote a long email to the store's costumer support, explaining the above. As a result, i didn't get my money back, but i managed to replace the phone with anything else i wanted in that price. So with my 599 euro store credit, i got myself a Nvidia gtx580 and 8gigs of ram for my PC. Happy days.

Feel your pain there fella and wouldent wish that bad experiance for anyone, the fact you got a gtx580 and 8 gigs of ram kinda puts the price of the phone in perspective and why we shouldent be content with these faults.

well third phone arrived today still got yellow tint , also has transparent lines that run down screen and if you use screen side on there is also some weird banding taking place , this has purple spot as well.
Totally gutted with samsung 3 phones now all with same kind of faults marks on screen yellow tint and purple spot. I said i wouldent but will trying one more exchange tomorrow then giving up on this phone.
Shame samsungs build quality is so bad :/

i had a very similar spot (to your 2nd sgs2). it was even bigger (1-2cm) and it had a very low mic volume.
so i returned it.
my 2nd sgs2 has still a bit low mic volume but its acceptable and the screen is just fine.
at first i thought i can see a battery through the screen but then it seemed more to be a dried up drop or something to me.

Since we are talking about build quality can i ask your opinion on the home button. Mine feels as if its craking when being depressed.
Is this normal?

Well, I think I'm very lucky, because I've bought my phone on eBay (no warranty) in the first month that it was launched (probably one of the first batches), and I have no issues at all. I'm extremely pleased with my device in all its aspects. Nevertheless, if I had experienced such issues (specially the customer service in Greece) I would be very disappointed also.

Likewise first batch no problems .
jje

No problem with mine. Although maybe on a very white image or screen the very left of my screen might be very very very slightly tiny bit darker. Could be me seeing things. Only started looking after reading threads like this though.
Doesn't bother me if it is because I can't really notice it.

My s2 was warped (crooked) right out of the box, low headset volume (even maxed via secret code) low mic volume and poor wifi.
I sent it in through bell for warranty and am still waiting to get it back. If my issues are not fixed I am selling it and never buying Samsung again. My sample should have never left the factory in that condition. At this price point, it's unacceptable.

Only problem with mine is a dead pixel and some overheating when playing heavy games. Its so amazing otherwise though

Got mine under the authorized dealer last month.
I have an issue with the speaker (Near my ear). When I max up the volume I hear a little cracking noise like what you hear when there is a small hole in the speaker.
It is not easy to notice but it bothered me.
And to no surprise, I take it to the service center , the did I firmware upgrade and told me there its nothing wrong with the speaker.
I took the phone and waiting till it worsens so it can be notable by the semi deaf technician.
love the phone and there is no alternative :-(

alarming amount of a complains for this phone.
i havent heard of any other phone having even 1\10th of the problems seen on this single hand set.
its is easily one of the most defective phones of 2011
not a recommended buy

Wow so many issues. I never imagined. Well my device was perfect from the start. Without a doubt the best phone I have ever had. It drives circles around my retired iPhone 4. Which to be honest I'm on my 4th iPhone 4. The first had a defective battery. The second the screen died on me. The third had a faulty home button after about 3 months. So now I am on number 4. Every time I got a new device, not refurbed.

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.
Sent from my GT-I9300 using xda premium

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
Click to expand...

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
Click to expand...

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.

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)

A mysterious screen problem.

Hello,
a few times I had a problem with the screen of my nexus and the so after 1 time display off and on it was always gone after.
This time I didn't turn off ​​the display and it took longer until it was gone. I had this when he Nexus was in stock condition, rooted and unrooted. Does anybody have an idea what it is?

If it was happening right when you got the device, then you couldn't have dine anything wrong. It kind if looks like A LOT of water got under the screen. Ad you said, your only options seems to be to RMA it.
Sent from my Nexus 4 using xda premium

This phenomenon appeared a week or two after the device was in use. No water, no crashes, no dust, or sth. else. I already mailed google for replacement.

Looks like water under the screen, there may be a way you can sort it. Suck on the headphone jack (genuinely), this worked on an old iPod touch of my girlfriends when she got droplets under the screen. Might be a bit too much in your case though.

I doubt that the source of the problem is water. As I said, the phone is in a perfect condition(no water contact) depending on being used by myself. Even the guy from the google support couldn't say anything about it Anyway thank you for your reply.
