Screen issues on SGSII

For anyone who is still monitoring this thread, I just saw this post tonight and read it from the O.P. that Cheema wrote . I ran the test and my screen was a very greenish color,the lines were barely noticeable but, they were present. I then ran the test on my Captivate, because I have always thought that the Cappy screen had better color, from the day that I got my SGSII. Which at the time seemed strange to me, although I just shrugged it off. So, when I did the test a second time I did both phones side by side and the difference was absolutely astonishing. The Cappy was as black as black could be and no lines or blobs. The T989 was a shade of army/olive green that sort of glowed in the dark. I think I will go to TMO and show them the two compared to one another and see the obvious difference. Considering they have basically the same screen it should be a no brainer to accept my wanting a replacement. I don't know if what I did matters or if anybody even cares but, I thought I would share the info.
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
Good luck, they just pretend not to notice it.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Going to a Tmobile store and comparing two totally different phones will be pointless....Now going over there and comparing two of the same phones with one having a better screen will be saying something.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] novanosis85:
I just received a replacement with not one blemish. Both were made in china.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
If you look very closely, the spots will be there, it just seems they color calibrated the screens much better.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] novanosis85:
Im sorry but I don't see anything. It really is flawless. :-)
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Don't be sorry, it's great that you don't. :D

I'm just sayin!

Called Samsung on Friday evening and set up an RMA to send the phone in and get it worked on. Today (Monday) they called me and said that if I haven't shipped the phone yet, I could come into their location and get it worked on - new program they are trying out. Since I didn't ship it yet, I made an appointment to go into their location in Dallas to get the phone repaired. The staff was very nice and helpful and I got to play with couple of their tablets while they repaired the phone in front of me - open window you can look into while they change out the screen or whatever work they are doing. Also got a free car charger for waiting/taking the survey. Overall great experience and cool program they have going.

Just an FYI for anyone that might live close to a repair center that is also running this new program. Better than waiting 6+ days to get your phone back.

I usually don't post much and just lurk, but was really impressed that I had to share with yall.

oh yeah and most importantly, my screen seems flawless now!
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
That's mad cool!

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
Where can I find a list of the repair centers?
[T-Mobile Samsung Galaxy S II SGH-T989] sleeptomorrow:
samsung repair center

you can find them this way:

1) google "Samsung repair center"

2) Click on the first link "Service Locations - Samsung"

***would have given you the direct link but i'm new... and apparently not allowed to post outside links.
[T-Mobile Samsung Galaxy S II SGH-T989] vim0314:
just make sure that the repair center has the walk in program. I didn't know about it till the actual repair center called me saying I can walk in rather than shipping it in. You could probably call Samsung and they should have a list of the walk in repair centers.
[T-Mobile Samsung Galaxy S II SGH-T989] ZetaiZetsubou:
I got my SGSII some time last year. (December?)

It was made in Korea.

The lines bothered me so I didn't use the phone for the last 4 months.

Finally felt like calling in and complained about it. Exchanged it for 20usd (service fee). The customer care representative was trying to deter me from doing this saying that IF they found any damage they would charge me.

Anyways, I got the new SGSII without this defect yesterday and it doesn't have this screen problem (It was a Made in China one).

Much better quality pictures, no lines and blobs easily noticeable at minimum brightness in dark room.

The colors are better too, plain blank pages like google don't give off a bluish tinge anymore.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
More and more success stories are surfacing up. That's good. It shows that Samsung are discretely fixing the problem.
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
Of course, this doesn't affect those of us who had this problem for months now.

And really, who's gonna buy a SGS2 now anyway? Wait for the HD version or the SGS3.
[T-Mobile Samsung Galaxy S II SGH-T989] monkeypaws:
Have any of you had this problem: in the last two days when I would switch back to home or web for example, if the screen was white, I would see these black/greyish blobs in the center of the screen. If I hit home or lock/unlock, they would go away. I tried to reproduce and take screen shot but I can't get it to happen. I was on juggernaut rom. A few weeks ago I got a one time issue where the screen flickered all rainbow colors, somewhat distorted butbit hasn't happened since. It does have minimal blobs and lines. You think I should exchange. Other than that I haven't had any issues whatsoever.
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
That sounds more like a software problem. The blobs/lines we're talking about are a hardware problem so they can't "go away."

I don't know whether they'll let you return it.
[T-Mobile Samsung Galaxy S II SGH-T989] monkeypaws:
If you were qouting me thabks for replying. I know what this thread is about. I thoufht it would fit. It hasnt happened again since then, but i thijk they should let me exchange it since it would be a manufacturing problem not abything ive done. I wonder if it was sone screen burn in. Anyway thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] sleeptomorrow:
in case anyone's interested in contacting Samsung directly about this for warranty repair or exchanges, I found out there is a dedicated Galaxy S-series phone support: 1-877-EZ2GALAXY (1-877-392-4252). 24/7. This is different from the general support number that is posted on Samsung's website.

*sorry if someone's already posted the info.
[T-Mobile Samsung Galaxy S II SGH-T989] keenerb:
Got a warranty refurb Galaxy S2 last week.

It has a much better screen than my old one.

I can't actually see any lines or blobs under any circumstances, and they were pretty easy to see on my previous one.
[T-Mobile Samsung Galaxy S II SGH-T989] funziebear:
So i came back after i used a note for a montn and half and i have to say big diffwrence on the newer devices screen wise i have non of the old issues
[T-Mobile Samsung Galaxy S II SGH-T989] JohnnyCrash:
Just tried this out on my Telus SGSII, in a pitch black room, i see no lines or spots with the blobs.jpg

I do sometimes see some streaking on a grey background, but i havnt seen it since i went to the ICS leak, thinking this may be software.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Hmmm, here's something very interesting. Today I bought the playstation vita and the newly released mortal kombat game today. It's about 11:38 pm and I just got a chance to open the vita and pop MK in. I'm in my room with the TV on and lights off. While completing an action in MK, the screen briefly transition to a blob.jpg color screen while changing to the next screen, Lo' and behold, I see a colony of blobs and streaks that are the exact same characteristics of the ones our sgs2 suffers from, in that brief moment of transitioning. and i mean I didn't even have to look hard at all to see them. It was like they slapped me in the face and said "I'm back biyyotch" lol.
[T-Mobile Samsung Galaxy S II SGH-T989] monkeypaws:
Does samsung make that screen?.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
I think the PS vita does use amoled as I think about it.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Just did my G search, and yep it uses Samsung's amoled......This just confirms that these spots are a natural process of amoled screens.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] :
Well it probably on all the screens. Just all screens are calibrated differently.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Yep, I think so.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] kCelsius:
I don't see why people make such a big deal out of this. I mean it does get pretty annoying when you're looking at your screen in a dark space but under most circumstances you aren't so it's fine.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
To each their own!

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] arrow123:
I just received a phone that was manufactured in April of 2012 and I do not see any blotches out lines on the screen.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Is it Korea or china?

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] :
I got a replacment yesterday no lines or blobs colors are more accurate and it is way brighter than my previous phone. Even at lowest brightness it hurts my eyes. I dont even bother using auto i set it down to the lowest brightness at all times.
[T-Mobile Samsung Galaxy S II SGH-T989] bkhc:
I have the best of luck with my International Galaxy S2 =(.

The original phone had the yellow tint on the left side, two vertical burn in lines across the middle of the screen, and blotches when viewing certain greys in the dark.

My first replacement didn't have the issues mentioned above. It passed the blotch test flawlessly, but it introduced new problems. It had horrendous viewing angles, where the screen would tint completely blue when viewing the screen 3+ degrees off centre. Also, the screen itself exhibited a very grainy texture when viewing grey coloured backgrounds from low-medium brightness.

My second (current) replacement gave me high hopes of almost being acceptable. I am still debating whether to keep it or to send it back for repair once more. The current replacement does not have the yellow tint, the burn in lines or the grainy textures. Viewing angles are still slightly tinted blue, but it is much less extreme and more acceptable than my first replacement. Unfortunately, it failed the blotch test miserably. The test revealed minor blotches on the edges of the screen which I find acceptable, but it also revealed a series of large scribble lines that covers 1/4 of the screen! I've read about the 'mura' affect as the resultant manufacturing process of OLED screens, but I've never encountered a 'mura' effect as extreme as mine. I will try to update my post with images later on.
[T-Mobile Samsung Galaxy S II SGH-T989] noah1017:
I don't know if this will help or if its been said but;

My first t989 was purchased in Oct.

It had lines and splotches like crazy.

I brought it to a kiosk and ordered a warranty replacement I received mid Nov.

The replacement had a better but not perfect screen but I kept my origional because the new one rebooted and failed every time it overclocked.

I just got my third t989 via warranty and its AWESOME

The screen is perfect, passes every test.

What I'm wondering is:

Is my replacement so much better because it was made latter?

It does not seem like a refurb, I'd know.

The biggest external difference is the qualcomm sticker on the top.

My original was in the right/middle and it said qualcomm snapdragon S3.

My new one has a sticker on the top left that says Qualcomm 4g

Anyone else have similar experience?
[T-Mobile Samsung Galaxy S II SGH-T989] drzplaya1121:
i received a replacement unit today with the colors much darker than my previous phone. When I had a nexus one the forum had an app to calibrate the rgb values on the screen to fix it to your liking.

Is there nothing like this for this phone? I apologize if this has been asked before but I skimmed through a few pages and saw nothing and i'm not reading all these pages word for word lol
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
well, awhile ago a member by the name of supercurio received a donated t989 from a bounty raise so that he can create this color calibration app. Last I read he was working on it, but nothing ever came of it. Maybe you can contact him and see if it still on his to do list loll.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] arrow123:
Phone made in China.

Date: 04/23/2012
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
I'm 98% sure this is the reason why your screen is appears good...... The korea's are the bad looking ones..... I've done about 4 warranties, and all 3 korea's had terrible screen issues. As soon as I received the china, I noticed the difference right off.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] ThC23:
So whatever happened with Supercurio and his so called screen fix??
[T-Mobile Samsung Galaxy S II SGH-T989] Nugenrules:
Do you guys think I should get mine replaced? I want it the best it can be, but is it worth the hassle?
[T-Mobile Samsung Galaxy S II SGH-T989] :
Gone. He never did anting as far as I know.

Deebo took your bike too?!
[T-Mobile Samsung Galaxy S II SGH-T989] :
I just got my Replacement refurbished today from TMobile and the screen is of much better quality. No blobs at all and the screen is darker when viewing a dark picture in a dark room.

Deebo took your bike too?!
[T-Mobile Samsung Galaxy S II SGH-T989] ThC23:
Ha, glad I didn't donate. He probably sold it and used the money to buy the SGS3 which he is working on....

Powered by the SGS2
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Maybe they can use it in a line while mackn' a girl down like " hey baby your cute,.... You know my t mobile sgs2 is gonna be 1st to get ics on 6/11, so hey I just met you and this is crazy, and here's my number, so call me maybe" lol

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Something went wrong because that reply wasn't supposed to be in this thread!?!

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] shnn2011:
Just bought 4 more t989s thought the problem was fixed. I got two Chinese black ones and two Korean white ones.

The Chinese ones are a bit better, and over all they are all a bit better than the old ones in general.

One trick that they apparently tried to pull is to turn up the overall brightness up.

The screens nearly all still suck.

And every one of the many i have bought (about 9 so far excluding replacements) ses to show colors diffrently. (crappy calibration?)
[T-Mobile Samsung Galaxy S II SGH-T989] kibosh1981:
I was wondering what the hell was wrong with my phone. When I first boot it, between the Samsung screen and the aokp boot when it is just blank, it almost looks like my screen has raindrops all over it. I was scared it was wearing out already or something. Although under regular use (like right now) the screen looks perfect. I'm running a telus t989D by the way
[T-Mobile Samsung Galaxy S II SGH-T989] fuse1820:
Mods: please delete post
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
Still no fix for this issue? Guess we're stuck then, now that all attention is focused on the S3 (which I will definitely not be buying because it has the same screen issues).
[T-Mobile Samsung Galaxy S II SGH-T989] richardlibeau:
All you guys are trippin. This phone is great the best I have ever had. Ain't nothing wrong with this phone. Mine works as it should. Don't like the shade issue try different theme maybe that will help some of you guys out.
[T-Mobile Samsung Galaxy S II SGH-T989] shadow_cruiser:
Can someone post the blobs.jpg please?. Link is dead in OP
[T-Mobile Samsung Galaxy S II SGH-T989] cpnfantstk:
My warranty is almost up. Doesn't seem worth the exchange from what has been described by some users. Some may have be lucky with a perfect screen but I never really believed the newer ones had the screen issue resolved. Last thing I want is to end up with a crappy refurb.
[T-Mobile Samsung Galaxy S II SGH-T989] panfist:
I'm also looking for blobs.jpg if anyone has it, please post. Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] mr_malina:
Its attached to the first post on page 1.
[T-Mobile Samsung Galaxy S II SGH-T989] demoncamber:
Lol... lucky me. I found out about this the hard way, after already buying a near mint phone, only to see the display has the line issue.

Was this ever addressed by samsung? Is there an update to fix it? Has anyone bought one of the $135 amoled screen replacements off ebay and has it fixed the issue?

Could someone please catch me up to speed here?
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
No they never addressed this issue. And now that this phone is two generations old I doubt they ever will.

No update to fix this as it's a hardware issue.

There is a chance the replacement screen is defective too, it would just be like getting a replacement phone.
[T-Mobile Samsung Galaxy S II SGH-T989] :
I find it funny mines is fine and some people never seen it till this thread. Why would you purposely look for fault in your phone. I can understand op his looks horrible. Everyone else I don't get it.
[T-Mobile Samsung Galaxy S II SGH-T989] landrian18:
I've just got my gs2 return.. the good thing is they wave the $50.00 restocking fee and since I pay in cash they also give the $318 that I pay... now ill be just patiently waiting for nexus prime....
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Same file displays fine on the Sprint SGSII. See the photos in the OP (T-Mobile unit is on the left). Both phones are setup identically and are sitting in a dark room.

If I view different content, it might hide the defects in the T-Mobile unit. That is correct. This is what is happening with many T-Mobile users. They are using their phones in such a way that the defects do not show most of the time. And that is probably why the phones passed QA testing.

Unfortunately for some of us, we use our phones in ways that do not hide the defects.

In the end, it is not too much to ask that the display in T-Mobile units behave similarly to the display in Sprint units. After all these are identical screens.
[T-Mobile Samsung Galaxy S II SGH-T989] mu0p:
Nothing "hides" the effect, the same lines are there no matter what image is on screen, it's just harder to see with lighter backgrounds. It's not just present with blobs.jpg. Load any other pic and you will notice it, mine looks identical to the one in the pic op posted, I noticed the lines before especially when using the cam in low light, no one here should be criticized for "trying to find" the issue here, we all payed over 500 and deserve a product that does what it says. I would just like to know if it's software or hardware, if it's hardware I'm over it, I gave Samsung one more chance after their horrid gps issue on the vibrant, which im amazed that was never recalled, so I doubt this one ever will be.
[T-Mobile Samsung Galaxy S II SGH-T989] :
First of all almost no one does this. This is purposely looking for an issue. . Go to Home->Settings->Display->Brightness. Turn off automatic brightness and dial down the brightness all the way to make it as dark as possible. 3. Open up the "Gallery" application and locate the blobs.jpg in the download folder and view it in a mostly dark room.

A pitch black room you would only be in one if in bed or at a party even then at a party you'll have some light. Under normal circumstances you wouldn't see it.

Why would you turn your brightness all the way down. Especially in the dark. 30% would be decent. This is purposely looking for it. In normal situations you wouldn't see it. Good luck to those getting the. Galaxy nexus because it might not have the drivers either and you'll be stuck in the same position as having a galaxy s2.

I put the jpg op posted on a different phone its not even really pure black?

The one i posted is pure black
[T-Mobile Samsung Galaxy S II SGH-T989] synenergy52:
I'm glad you posted this. I have posted videos on YouTube and have written Gizmodo about it complete with pics/video. This is an obvious glaring problem and it's sad that people need tests like these to see the problem--they must not have a detail-conscious mind or a detailed eye. The dark room/low brightness setting against dark backgrounds definitely exaggerates the problem with the noise/blotches/lines. The OP is 100% positively telling the truth. These displays are downright defective and I am in the same boat as you. I'm on my second T989 and it did the same thing my first one did. I am also convinced they're all like this.

Signed.

Sealed.

Confirmed.

OP you are 100% correct. I want this to turn into a 30,000 page thread. This needs to go BIG. NEWS BIG. This is not acceptable!

---------- Post added at 10:06 PM ---------- Previous post was at 10:02 PM ----------

You're missing the point. These tests aren't necessary to see the problem. Only necessary for people who have vision problems or who can't distinguish fine detail. Brightness doesn't need to be 0%. This is JUST FOR YOU GUYS who don't see what we're talking about.

Normal situation laying in bed watching youtube videos YOU WILL SEE IT. Going outside in the sun you WON'T see it. Or even in a brightly lit T-Mobile store. This is NOT looking for a problem, this is a problem staring you in the face... and laughing at you!
[T-Mobile Samsung Galaxy S II SGH-T989] :
Then take it back if you don't like it. Samsung can't do much with out drivers. Because the qualcomm chip doesn't support it normally they already had to hack and slash to emulate the drivers. If i have to do all these task to see a lines is it really worth it? You picked up the device looking for flaws in it once you know it didn't have the infamous original samsung processor. Thing is you can't even blame samsung you'll have to blame t-mobile for changing the processor. There is the amaze 4g as well and you know how many hardware problems that has? You expect a company to go out of their way to make drivers that don't even exist?:confused: You can fix it by providing better emulation for the drivers so that the gpu can render it better. But its only so much you can do when the gpu isn't even that powerful.
[T-Mobile Samsung Galaxy S II SGH-T989] Splaktar:
Better to just use the 'Dead Pixel Detect' app rather than some random .jpg that someone posted in a thread.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Did you read step 1 in OP?

You may want to re-read it.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Why would anybody use dead pixel detect app, when nobody has said anything about dead pixels here?

We have a problem with color and saturation. Not dead pixels.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
As someone else stated, the steps are listed here to show people who cannot see the defect. Some of us see the defects, almost all of the time without trying at all.

If the only way to see the defects was to follow the steps in OP, then we would all be very happy.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Samsung can't do anything about drivers we don't have. You do know our phone is not displaying properly because of that? Were emulating the drivers from the original galaxy s2.
[T-Mobile Samsung Galaxy S II SGH-T989] babymatteo:
So yah i think i have a bad display too...plus i also notice a black stripe running down the right side of the screen. It kinda looks like a dead pixel formed into a stripe. I bought my phone from Tmobile.com, you guys think i can bring it back to any store and request for an exchange there?
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
No offense, but you're not really making any sense.

If you're not bothered by this, great. No need to keep posting about how you're not bothered.
