Okay, so I got my 5th phone on tuesday. this has a date of 1/12/2012 (jan) and same problems as the last phones. crack on left bottom- light leaking through. this time, the buttons have dirt built into it lol! again, you can only see these if the key lights are on. I GIVE UP!!! I am sending it back to tmobile and fighting the urge to get another in hopes of a almost perfect replacement. Thing is, why are the newer batches having physical defects? the screens on them are better than the one I have originally but I am not willing to part with it.

oh yeah, something was wrong with the battery on the last phone.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Instead of continiously getting refurbs why not speak with retention. Tell them that you are on your fifth and almost sixthbhandset. You are very dissapointed andbhave them sebd you a brand new one or credit you to get a nrw one at the store. They are just wasting your time and arent getting good results. Idk why you are hetting faulty equip man. All my warranty phones ive ever had have been close to new quality and performance.
[T-Mobile Samsung Galaxy S II SGH-T989] han-shinbi:
They are all brand new in box. I am within my remorse period and these are the new batches. I have to call retentions everytime so whatever their warehouse has, that's what I'm getting. Now that I think about it, I can't recall a time I ever got a good handset from them.:confused:

Got a SGS II last week and had the spots and a couple of lines, not too many. The lcd failed and produced a bright green screen no matter what I did so I had it replaced for a brand new one today and I'm sorry to say guys but its flawless. and by flawless I mean it has less flaws than a broken iphone 4s 3 miles deep into the pacific ocean next to the ring of fire.
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
Lucky you, I wish my phone would produce a bright green screen so I can get it returned.

Pop it open and cut the traces supplying the Red and Blue pixels color. LOL its using standard Philips screws. I know of at least one person who popped one open then returned it for warranty.

Pretty much it's a give or take issue. Either you have bad lines with no blobs, bad blobs without lines, or medium lines with medium blobs lol! No perfect screen exist to date!

ya I noticed this when i first booted up my phone. There are like black dots and lines all over the screen.

I thought it was just my phone, i was going to sell it and get another one but i guess that wouldnt help

No problems here and I'm extremely picky! Phone was purchased this weekend. ZERO light bleed, no issues with camera images. I originally though the display was a little "bluish" but you have to crank it down ALL THE WAY to get it that way. In super bright light a little even with full brightness but I looked at a Galaxy Nexus by Verizon and the SG2 is significantly brighter and clearer. Don't have the blob or line issues. I did inspect the phone before I bought it and the first one had some screen alighnment issues where there was a bigger gap at the right vs the left (like a piece of paper width) so I asked for another which was fine. The screen is not an IPS or PVA for gods sake and image quality should be better than decent but not perfect.
[T-Mobile Samsung Galaxy S II SGH-T989] I'mDan2:
Finally, a good screen!

4th phone. Kind of a pain shipping phones back... got to know the UPS store folks well. But I'm really picky and wanted this phone to live up to my expectations. This one shows mfg. date of January 20th. No lines, no blobs, no yellow tint. I'm thrilled! Don't know what to say to folks having problems except that there are good ones out there. I'm wondering if they sorted out some mfg. problems and that the more recent units might be better. I don't think any software tweak would have fixed my earlier units. Pretty certain it's hardware/mfg. issues. Don't know for sure, but I'm finally a satisfied customer.
[T-Mobile Samsung Galaxy S II SGH-T989] jtroye32:
Darn, mine has a MFG date of 1/13/2012.. I might have missed a good batch by a week. I'll contact Amazon Wireless and tell them not to ship me a new one until the MFG date is at least 1/20.

And the burn-in issues.
[T-Mobile Samsung Galaxy S II SGH-T989] I'mDan2:
My bill looked like that. Took awhile for the credits to apply. Call them, you should be able to just pay your normal bill until the returns are credited. Do they show them received back? It still takes 2 to 3 weeks after that before they're considered credited to your account.
[T-Mobile Samsung Galaxy S II SGH-T989] han-shinbi:
Yeah, I just contacted them. They're gonna do a handset research for each of the returned phones. That, plus my corporate discount 10% is getting less than for some reason. This is the last time I'm ordering from them-will just go in store now.

Third Warranty to Samsung...

(CHAPTER 1)

I called Samsung many times, starting in December 2011 (When I first got my phone and noticed the "lines"). Finally, last month I got them to recognize this defect, at least I thought so, so I set up a Warranty.

They claimed the SGSII has a special turn-around time of 6 days, 2 days to get there, 2 days to "fix" it and 2 days to get it back into your hands.

They'll send you a UPS Label (Prepaid) 2nd Day Air.

I got it back, pretty much in the 6 days, but nothing changed, they updated my software (GEE THANKS, just what I was hoping for, lol). NOT FIXED!! NOT EVEN ADDRESSED!!

------------------------------------------------------------------

(CHAPTER 2)

SO, I called right back and sent it right back to them, they promised to fix it and next day air it back to me. They told me to make it attention to "Repait Manager" (There is a special Galaxy SII Department - Ask for it, they might play dumb at first but ask for a Supervisor and they'll suddenly remember )

Here's the info from my Repair Ticket (online at Sammy's Website):

*02/01/2012//20:06:36//***********//Telephone//ASC*

2/1/2012 7:05 PM-JK: The unit has left the technician. SOLUTION: Replaced LCD - Replaced Touchpanel

------------------------------------------------------------------

(CHAPTER 3)

When I got it back that time, I popped it open, slid in my battery, clamped on the back, booted up and saw... the lines/streaks or course; a little worse this time, I feel.

(A nice grey splotchy line across the top as an added bonus)

I immedietly called Sammy back and asked for the "Galaxy Dept".

I got him up to speed on the whole story, and told him it still wasn't fixed, in fact a little worse this time. He told me to RMA it again, and make it Attention to him "Ellison"; he will call me when he has it in his hands and walk it over to the engineering dept (Supposedly).

I cleared all the stock shortcuts and widgets, set it to lowest brightness (Auto Brightness Off) and picked the wallpaper that showed the "Defect" the best. This is the second time I've gotten it back and had to immedietly box it back up and send it right back to Samsung.

Taking their sweet ole' time, as always. I know they received it last Friday morning. I call them almost everyday to harrass them, I think they are starting to "know" me, lol. (Which is good ;-)

I got a better # 18773924252 (1877EZ2GALAXY) direct to Galaxt Dept. (you still have to ask for "ECR" Executive Customer Relations)

I actually got Ellison on the phone again, he said he sent it over to the "Engineering Dept" to check out and will call me when he gets it back.

(But, he also mentioned that "He didn't notice anything, when he had a peep at it) - well, that sounds promising doesn't it, lol...

I called a few more times and got an email address to the "ECR DEPT.", I sent over some great images/pictures, that show the "Defect" perfectly, so we'll see what happenes now.

Getting really pissed off, over a month without a phone and counting, so far...
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Chaos,

Thanks for updating us on the saga. If enough people raise a stink, somebody at Samsung will eventually wake up and pay attention to the display issue we have all been screaming about for months.
[T-Mobile Samsung Galaxy S II SGH-T989] Naldonnis:
Yeah they were doing the same thing to me. You have to call them amd stay on them other wise they will say that you owe that much. Mine was up to $2100 and by the time I got done it was down to $143.
[T-Mobile Samsung Galaxy S II SGH-T989] darkphantom:
I'll tell you how to reproduce the screen issue, go into any tmo store and buy a new SGS2.

Ordered a white GS2 with an Amaze 4g, the GS2 had the same issues w/ the screen. Boxed it back up, selling it off.

Keeping the amaze - just so much better build quality!
[T-Mobile Samsung Galaxy S II SGH-T989] Oliv3:

I am the OP of this thread. I have finally given up all hope of this issue being resolved through any reasonable means. I have sold my T989 and bought a Samsung Galaxy Note (International version). Screen on the Galaxy Note is flawless.

My wife still carries the T989. The poor quality screen does not bother her.

I think they're fixing the issue now, I would advise those with the issue to warranty exchange at this time. Not only does not the spots and lines show at any brightness setting, the colors are also much richer with this unit. Crisp and clarity looks like the sprint version.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
International Samsung Galaxy Note does not support T-Mobile HSPA+. I believe the best it can do is Edge on T-Mobile. Not recommended. It does work great on AT&T and that is where I am currently using it.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
It is very possible that the units have fixed this issue. The only solid way to verify this is to follow the steps in the original post and put it next to a Sprint version.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Recieving this unit has given me validity that your theory is more on the money cheema. Looking closely at my new unit, I can still see the spots and a horizontal line streaking across "BUT" this time it's different. This time, I really, really, really have to strain to see during the blob.jpg test. This leads me to believe that the spots are normal, but the screens were not color calibrated correctly. Even the screen is a different color while performing the test. The screen color looks similar to the sprint units you were testing in your previous posts. During normal usage, even in the darkest environments, with brightness set to either highest or lowest, while watching netflix or youtube, the spots and lines cannot be seen at all, my colors are much vivid and richer than any of the previous exchanges I've received! I highly urge those with the problem screens to warranty exchange your unit.
[T-Mobile Samsung Galaxy S II SGH-T989] jtroye32:
I might warranty mine if more can confirm they are actually fixing/improving the issue. Mine isn't bad but it's not good either.
[T-Mobile Samsung Galaxy S II SGH-T989] sfsilicon:

Guys this issue is not new. Had it on both of my Vibrants and on my Captivate but worse. Discovered it by accident once when I had soft bricked one of my Vibes. Now I have a GSII with same problem but not as bad so idk if I'll even worry with it. It is only noticeable under specific situations. No two screens are alike and if you get one that is perfect you really lucked out. I say unless yours is very bad I wouldn't even worry with it. I can live with the blobs if my screen has good color reproduction and contrast which it does. Cheers.
[T-Mobile Samsung Galaxy S II SGH-T989] Enzopreme:
i really dont see how this can be a GPU related issue, considering the fact that the lines and blobs dont move with the image, i think its clearly a screen hardware issue, so, unfortunately for us, an update or software fix is probably not in the future for us. But i dont think I or anyone else is gonna use blobs.jpg as a wallpaper, and i cant notice it on any other images, so is it really that big of a deal?

Most of the artifacts/defects that the test shows don't show up in day-to-day use for me; so although a bummer, it's not a dealbreaker. I still *love* my phone. :D

If you have to go through so many steps to realize your display is not up to your standards did you ever think that maybe you're nitpicking?
[T-Mobile Samsung Galaxy S II SGH-T989] derpatronic:
I notice it when lying in bed watching Netflix in the middle of the night. And it's not super noticeable.

Other than that, it's a non issue.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Anybody who does not see the issue should happily continue to use the phone. Different people use their phones in different manners. Some people will see the problem more often than the others, depending mostly on how they use their phone. The steps listed in the OP are there to prove beyond a shadow of doubt that the problem exists, for many of us. I do not have to follow the steps to see the problem. I see the lines, the washed out colors on photos all the time.

When I first got the phone, I immediately knew something was wrong. I was using the phone to read a document on a web site where the background color was not pure white but a subtle shade of gray. I was reading the same document earlier on the Sprint SGS2 earlier and there the experience was quite pleasant. On the T-Mobile phone, the contrast was quite bad. And the gray background accentuated the problem.

That is what made me look this problem up and noticed that others were having the same issue. And then I observed that the colors in photos were washed out too. (See my op for link to my photos).

I am hoping that by raising awareness of the issue, we can get T-Mobile/Samsung to take action and fix the problem.

I like the phone and do not plan to return it. However I would certainly be happier if the screen issues were fixed via a software update.

This. And after I turn my screen up to 10% or so it's not noticeable. I STILL think the screen is great. I'd rather deal with this minor annoyance and have the fantastic contrast in direct sunlight these screens have
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
This issue I noticed right off when I first bought the phone. For me, it showed when watching movies. I saw the vertical lines in certain scenes but at the time I didn't know exactly what I was looking at. It wasn't a big deal, but noticeable under "normal" condition.
[T-Mobile Samsung Galaxy S II SGH-T989] rodolfo7171:
Lol I didn't even notice it til I was in bed and I rebooted my phone I saw a couple blobs as if it was dropped in water but I could never notice it any other Time. even with the screen lit to max and all black screen.

I also compared it to my galaxy a vibrant and I could see that that one had it too but wasn't noticeable but could be clearly seen on the edges.

I say all these phones have that problem. I just don't think it's noticeable unless you,look for it
[T-Mobile Samsung Galaxy S II SGH-T989] :
Storm in a teacup?

I tried the OP's suggestion, and to be truthful, I did notice a very little splotching on a dark gray/green background, but the room had to be pitch black. This is certainly not the kind of thing I think the average user would see under normal conditions (based on my device, but ymmv).

I'm not sure, though, if this is a display fault or the fault of the rendering of the jpg file or of the file itself. Some jpg's can have artifacts that can only be seen under conditions. For example, a picture may appear fine using a lower quality screen, but show splotches and other distortions with others, even those of the same resolution. I've done enough desktop publishing and photo correction to know. (BTW, an anlagous thing happens with printers.) In the end, this may, contrary to the OP's view, be an indication of the quality of the display (in that it shows the faults of the jpg) and not its lack thereof.

But further, I also question whether the issue may be related to the calibration of the brightness function. It could well be that this is where the issue lies and the reason why is seems to show on some Tmobile variants, and, according to the OP (and I take his/her word for it, though I have not tried it myself) not on the Sprint version.

Finally, I just must address the rather silly claims that "T-mobile Units have bad contrast and "Colors in pictures are washed out." First, the OP hasn't tried them all, so he/she cannot know that for sure. Second, when I investigated my purchase of the SGSII, I looked at various variants. My conclusion was that I (with a very critical eye) really could not tell the differences between them with respect to screen quality. My unit has the best quality screen I have ever used on an android phone. Even at the lowest brightness setting, I can still usually see it in the sunlight. Of course, our sun seems to be not so bright in NW Ohio. (I recently moved from VA Beach and I'm still a bit bitter. :) )

To sum up, then, this appears to be a storm in a teacup! The fact that you have to go through these kinds of machinations to produce the problem suggests to me that something might be fishy. (Come on, how often would you really sit in a completely dark room and stare at a black jpg with the screen at its minimum brightness?!) But even if we grant with the OP that there are some minor artifacting issues with the rendering of a very miniscule amount of jpg's under specific circumstances, it sure beats the hell out of working this device on Sprint's pathetic data network!
