Just because the name isn't saying what you want doesn't mean that it won't help with the issue you are having. Have you even tried it? It displays full screens of the different colors (including pure black). It is good for comparing the color saturation and pure blacks between devices.

There are other threads that cover this. But no, you can't bring it back for an in store exchange if you bought it online or over the phone. You have to mail it back in.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
I expect my phone to have correct color and saturation, like the equivalent Sprint phone. I think this is a reasonable expectation.

I personally do not know what is causing the screen issue. If I had to guess, I would say it has nothing to do with lack of availability of drivers. But more to do with incorrect display settings. The lines are there on all Super Amoled displays. However we don't see them on the Sprint unit, under normal circumstances because the displays are setup with correct color and saturation values.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
I am trying to hard to understand your logic. The issue we are having is staring us in the face, literally. See the picture in the OP.

How exactly is the dead pixel detect app going to help solve this problem?
[T-Mobile Samsung Galaxy S II SGH-T989] :
Qualcomm processor doesn't have specific drivers for this device. As stated by supercurio http://j.mp/vzq10t. He also stated that are chip is emulating a chip in the original galaxy s2 http://j.mp/uW3Rlx. It may be able to get fixed but it is very unlikely due to tmobile changing the hardware in this device we have little to nothing in common with the galaxy s2 variations. In order to fix what you want Samsung would have to fix drivers that don't exist due to the

Qualcomm cpu/gpu combo.

Samsung would have to make a driver from scratch with little support from Qualcomm. Your problem will most likely will not be fixed.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
Hopefully this issue is corrected with the Telus Galaxy S 2 that is released tomorrow and we can use their drivers.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
This is what I am waiting on also. We can only hope. Don't know if it will help but it's worth a try for sure.
[T-Mobile Samsung Galaxy S II SGH-T989] :
I seriously highly doubt it. Emulation can only do so much compared to the real thing. We don't have the same internals as our variants. If they do fix it its going to

have a hell of a toll on performance and battery life. Our hardware would have to be pushed to its limit to do so. How capable is this processor really? When it has to emulate a chip we don't have every time the screen is on. It is mostly on the hardware side of things. Which most likely won't be fixed. Samsung would most likely going to overclock the gpu 2-3 times. They would have to code better software emulation to get exact results.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
The emulation is being caused because the gpu drivers are not optimized for this phone so if the Telus version has an optimized gpu driver than hopefully we can use it since it will be the exact same phone as ours.
[T-Mobile Samsung Galaxy S II SGH-T989] mu0p:
I don't get it, do you always bend over to corporations who screw you over? No matter who is at fault, we ALL paid money for this phone, and no where does it say "Oh the screen will look sub par to what it actually should look like" And no, NO ONE went looking for this problem, if you see the OPs original thread stating he was seeing lines BEFORE posting this pic, this pic is just to show how obvious the problem is. I noticed on my phone as well before this thread, when using the camera especially. I'm sick of bratty people who can afford to have a purchase be such a flop saying "whatever, whos going to fix it??" THE COMPANIES THAT BUILT AND RELEASED THE PHONE WILL. THEY SHOULD be held responsible, it makes no sense for a company to get away with things like such, this is no different then the vibrants annoying gps issue, I was on the phone with tmobile for weeks before they finally sent me a free mytouch4g. And looks like I will be on the phone for weeks on again. If this is the fault of tmobile, then why did they release the phone. Same things goes for samsung. This will NEVER be recalled, because it would KILL the company and cost them millions. But in reality, they should be forced to recall the item, and left to burn for their mistake, overall, thats how true capitalism works. I'm praying this is just a driver/software issue.
[T-Mobile Samsung Galaxy S II SGH-T989] :
We have more of a change to update as the ota update for Wifi calling might bring fixes. The telus version might be worst off then us.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Silly. You draw this all encompassing conclusion from testing one phone? Meh. I can assure you I have no such issues.

[T-Mobile Samsung Galaxy S II SGH-T989] :
Oh boy oh boy. 2 phones! That makes a whole lot of difference. Lol! :) Okay, drunk and all those interested. We should not make such sweeping generalizations as the OP has done on the basis of so small a sample. This is especially true when you have contradictory evidence. That's why the grandiose notion of "detailed testing" with the concomitant conclusion that "Tmobile phones..." is rather silly.
[T-Mobile Samsung Galaxy S II SGH-T989] vinterchaos:
have you failed to notice the 100s of other posts about the screen in other threads and whatnot?

while most of us are willing to overlook it, that doesn't change the fact that there is definitely a good percentage of us noticing the problems with the screen
[T-Mobile Samsung Galaxy S II SGH-T989] :
I've read almost the entire Tmobile Galaxy SII forum and have not seen "100s" report this issue. Frankly, it's this kind of overstatement and hyperbole that causes companies not to take our forums seriously. I remember a time not too long ago when XDA-developers was a place where real, objective work was done. I'm not suggesting that some phones don't have display issues. The fact is that with devices this complicated and screens this complex, you're bound to have a few duds or even a batch of duds. However, these blanket and poorly researched statements promote hysteria, kill our credibility (a la the boy who cried wolf), and fill our forums with clutter. Well, nuff said. Kthxbai.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
The original post is about the most real and objective work on the topic of T-Mobile SGSII screen. If you know of any other similarly researched piece of information on this topic here in this forum or elsewhere, please point it out to us so that we can know what you are talking about.

It would also be very interesting to see anybody come up with something more solid than "My phone looks OK to me" to discount the original post. While such statements are well and good for the individual, they are not scientific.
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
Just got mine with a 10/01/2011 date stamp. Confirmed that I do see this greenish lined thing.
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
be more specific

SAMOLED+ devices are known to have a hint of greenish or blue tint to some people eyes

usually green from the left and blue from the right
[T-Mobile Samsung Galaxy S II SGH-T989] :
This samsung galaxy s2 has it as well in this article http://samsunggalaxys2review.org/ho...msung-galaxy-s2-samoled-plus-screen-at-stake/

Ironically someone says you can fix this with the chainfire 3d app.

click Nightmode

tick the checkbox

then select COLOR and Choose custom at the last

in custom you will se three lines R,G,B

SET IT IN A WAY THAT THE LAST LINE IS

IS AT FULL

AND THE ABOVE TWO LINES ARE SAME AND LITTLE BEHIND THE LAST LINE…SUCH AS

I don't have the app to test it with? Seems your able to edit the colors with this app. It may or may not work for our variant of the device.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
I had the nexus S, and it had the same vertical lines as well. It was mostly noticeable when you pulled down the notification bar. I really don't think this is a defect.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
How do you explain the pictures in the original post? Specially the ones in the reading test? Why do the screens on the Sprint phones always look so much better?

We all wish your statement was true and there was some evidence to support it. If you find any such *evidence* let us know.
[T-Mobile Samsung Galaxy S II SGH-T989] laafiera:
Uhmm... I got my doubts after doing a test run on each individual of the primary colors my phone perform perfectly fine... You can try it yourself by dialing " *#0*# "
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Like I said in my original post, statements along the line of "My phone looks OK to me" are well and good for an individual user. However it absolutely does not prove that your phone has correct display settings.

Sure I can punch in *#0*# and ask the phone to show me color blue, for example. And it will show me blue. Any phone with bad contrast will do just that. You have to put your phone next to a phone with a good display (Sprint phone) to see what is going on. For example you can simply run the front camera on both phones, in less than ideal light, and look at yourself on the display of both phones. And then come back and tell us that your phone is performing "perfectly fine".
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
This will also make you possibly lose your lockscreen and shutdown option.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Shoot. It did just that to my T-Mobile SGSII. Lock screen is gone and so is the power menu. At first I was reluctant to punch a code in my phone that some stranger on a forum suggested. Specially one that appears to be a big believer in subjective testing. But I decided to gamble. And it appears, I lost.

Anyway, does anybody know the process to reverse this change caused by laafiera's suggested code?
[T-Mobile Samsung Galaxy S II SGH-T989] :
Try reboot or factory reset.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
Factory reset will work but I'm not sure of another way. For those that wanted to get rid of it, its a good thing LOL.

Resetting and battery pulls wont work. Check you screen timeout also because it resets that sometimes also.
[T-Mobile Samsung Galaxy S II SGH-T989] laafiera:
Wait a minute!... First you're Not changing any setting by entering the code. *#0*#, that's the official code used by samsung's tech support to test the hardware functionality of the phone.... So if something doesn't work on your phone now it probably didn't work before entering the code!
[T-Mobile Samsung Galaxy S II SGH-T989] matthenry87:
+1 I was showing my co-worker this app today and afterwards we couldn't figure out why his lockscreen and power menu were gone.

Doing the *#0*# triggered this bug. That's unfortunate because I was gonna use that test menu for troubleshooting phones but now I can't (at least on the SII)
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
So I just got the Telus version of the SGS 2! I love the phone, but it has the display issue (blobs.jpg) and I am not sure, but I might have the battery issue as well, but it looks to be stuck around 65%..

Has there been any fixes for the display issue as it seems to be affecting a lot of people.

Also, does this display issue really turn people off to the phone? I really love the phone and don't want to return this amazing phone :(
[T-Mobile Samsung Galaxy S II SGH-T989] laafiera:
Crap!... I just realized that!
[T-Mobile Samsung Galaxy S II SGH-T989] lookitzjohnny:
Make a petition on change.org and demand Samsung to do something! Just a thought. We shouldn't have to pay $300+ dollars to get a half-assed phone compared to the other galaxy s II devices.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
Me myself I have the problem with the blobs but I like the phone so I live with it. I'm on my second phone and can't see going back and fourth changing out phones. I can't see it 90% of the time. Do I want a fix?? YES but not going to return the phone just for that. The other galaxy s II's have it but it's not as visible. Maybe Samsung will tweak our screen settings on a upcoming update and we won't see it as much.
[T-Mobile Samsung Galaxy S II SGH-T989] billydroid:
So this issue is also with the international sgsII, according to that article. It's a real issue, not nitpicking, as some keep saying.

My screen it's awful. Also, the chainfire3d nightmode does nothing, except slow your phone down.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
I can confirm that reboot/reset does not work. However factory reset does work.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
If it exists with the international version, it is not widespread. There are very few reports of this problem on the international version. And there are 0 reports of this problem on the Sprint version. And on the T-Mobile, there are too many reports of this problem.
[T-Mobile Samsung Galaxy S II SGH-T989] :
I think it is just super amoled in general. The only update I can seem them fixing it is ota update for wifi-calling. Both amaze 4g and sgs2 will most likely get bug fixes as well as wifi calling in the ota. Samsung fix might also be worst then what we have now as well. Just to keep that in mind.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
The performance of this phone in the reading test (see the pictures in OP) probably bothers me the most.

I see the lines when I am taking pictures in low light as well. But I can probably live with that. But if I cannot read something clearly that I can on other phones, that really bothers me.
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
Thanks! I'm just trying to be reassured that I don't have to replace the phone.. I had too many issues with the SGS Vibrant I don't want to relive this.

Do you own the Telus version or the T-Mobile version? What do you think of the display other than the blobs issue..?
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Has it ever been proven that each of the 3 sgs2 displays are made exactly by the same manufacturing plant???
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
i have the T-mobile version. I like the screen other than the defects that have been covered in this thread. I am coming from a long time with HTC phones so this screen is great compared to those washed out screens. My opinion but this screen has the best colors I have seen on a phone. Saturation could use a little tweaking but other than that it's great.
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
So even with the blobs, you are still going to keep the phone? Hope that there's an update that could fix something with it?
[T-Mobile Samsung Galaxy S II SGH-T989] billydroid:
Good question. When I had a mytouch4g, there were a Twain and chinese version. The former suffered from a horribly washed out screen.

I just chatted with Samsung mobile support. "Sophia" advice was to a factory reset. Of course.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
Yeah only because I got my phone for next to nothing. Some people paid $500 for it and some paid t-mobile prices. I got mine for $80.00. Blobs don't matter as much when you paid a small amount. Like I said it does bother me they are there but no reason to get rid of the phone over it. This is my first Samsung phone and I'm going to enjoy it till something better comes along or until we get word on ICS. Development seems great so far and this community is great. I'm good for now. I am a phone whore though, so we will see.
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
Haha, I bought the phone for $600 outright, so I am a bit stressed out now, seeing as there are blobs and lines on my Telus version.. For $80 it would still annoy me but it wouldn't freak me out as much as $600. :(
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
In the end it matters little if the displays were manufactured in different plants or the same plant. The fact remains, we have an issue with our displays.

I am of the opinion that the the physical displays in all of these 4 phones I tested are fine. But the T-Mobile ones are setup/calibrated incorrectly. I do not know if this is something that can be fixed with a firmware update.
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
I sure hope that it is just a calibration issue and it is only a small update :)
[T-Mobile Samsung Galaxy S II SGH-T989] ThC23:
Ok so I picked up my 2nd phone today, first one had shut down issues.

I don't have the lines, but I do have the black dots /blobs.

My question is-

Unless I'm looking at that grey wallpaper I can't see them anywhere else.

So what's the big deal with them?

Will they get worse?

I've looked at Pics, videos and different screens and nothing.

Are other people seeing them somewhere else?

Other than that I'm really happy with my second one, it runs smoother and its snappier. (Stock)

Don't think ima return just cuz of that.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Actually it does matter. If all 3 carrier sgs2 displays are manufactured at the same plant then yes it would be safe to say that this is a legitimate defect, based on the inconsistency. If each carrier sgs2 displays are from different plants, then how can you assume that the least pleasing (from your opinion) display is defective without knowing the facts of how the screen was made. Maybe subtle differences in material and processing can produce a slight difference in comparison to others, but doesn't necessarily mean it's defective because in your opinion the lines are ugly...... Hell I think the lines are beautiful, that's my opinion. But what are the facts???
[T-Mobile Samsung Galaxy S II SGH-T989] Splaktar:
Tried it. It did some cool things with colors on my screen, but nothing really helpful. It did not have an effect at all on the vertical lines. I didn't test the 'blobs' because I can't see them except on a pitch black screen in a pitch black room which isn't a use case that I care about.

It will fix your screen if you see it being too green/blue, but I do not see my AMOLED screen as being too green or blue. It did really seem to lag my device down when the Chainfire 3D drivers were installed. Swiping home screens and app screens had major delays and sluggishness.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Well I already lost 50$ for returning the amaze, and if exchanging it makes it worse. I'd rather not be out another $50 for returning this. Paid full price. I'm willing to live with it because the other 99% of this phone is worth it and if this issues will definitely not degrade my screen after a few months.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Its actually hard to see the black dots when the screen is using dominant colors. You can't see it as well if your brightness is around 30% or higher. On a lcd screen they would get worst but on a oled screen like ours they won't do anything.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
How do you explain the difference between the screen performance of a Sprint phone vs the T-Mobile phone (See the original post)? They are both 4.52" Super Amoled Plus displays with 800x480 resolution.
[T-Mobile Samsung Galaxy S II SGH-T989] SamsungVibrant:
Owning the original Galaxy S Vibrant I wanted to chime in a little.

When the original Vibrant came out and the respective variants on the different carriers, all the screens were different. Actually not just between carriers but between handsets. For example all the phones had different tints. Some had blue tints, some had green tints, some had grey tints, some had brown tints, and some had red tints. Meaning no true whites were visible, the phones had a tinted look. By nature Amoled displays will look more "blue" than other handsets.

You could open up a box of 20 different vibrants and they would all have different tints. I remember the Sprint Variant most of them had a brown tint.

Secondly, the vertical ghosts are normal. I have played with many Galaxy S phones from the Vibrant to Captivate, etc...and they all have the vertical ghosted bands. I have no clue what causes it.

3rd. Some of the issue is with calibration. Which is a software issue, and once you guys get custom kernels and stuff like that you will be able to calibrate your screen. This same issue plagued the original Galaxy S, didn't matter which carrier the phone came from. Finally a developer named "Supercurio" came out with "voodoo color" for all the original Galaxy S phones which allowed for screen calibration.

Please visit:

http://project-voodoo.org/color

You will see voodoo color in action and also the tint problem I was talking about.

I say keep the device, in a few weeks you won't even notice it. You are all only noticing it now because you are super analyzing your new

phone.

Edit:

I just read this that someone else posted, I don't know what supercurio means. Maybe the problem isn't software related:

http://xdaforums.com/showpost.php?p=18875566&postcount=439

"Um its not non sense supercurio said it himself.

"supercurio: T-Mobile #GalaxySII uses MSM "MDP" processor to emulate Samsung mDNIe chip and processing on its screen. No comment..."

--http://twitter.com/supercurio/status/129372251081551873

Qualcomm chip don't have drivers to process super amoled. So Samsung can simply fix it with software. If its just an emulation by making a better code. But then again that depends on power of our gpu."

Edit again:

The calibration issue I meant was about the tint, not the vertical ghosts.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Supercurio does development for voodoo sound and screen tuning. Obviously he can't do it because we don't have the drivers. Our variant of the galaxy s2 is only in name. Everything else we are a totally different device.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
As I've stated before, when I first got the nexus S, I saw the same ghost vertical lines as well. They weren't as pronounced, maybe do to the smaller display, but prevalent. I remember watching a tour of the nexus S on a major blog site before I bought it, and an editor had pointed out the same thing when pulling down the grayish notification bar. Only then were you able to see it. The editor simply pointed it out in questioning whether it was normal or not but didn't make a big deal of it. Look how long ago that was. Yet still samsung has continued to use these displays. With that being said, we should properly address whether samsung would really consider this a defect or are they just cheap quality displays used to help cut production cost?
[T-Mobile Samsung Galaxy S II SGH-T989] :
Emulation usually is not as good as the real thing. No matter how powerful your computer is if the emulation software is not coded good enough your going to have problems. Even if your code is lets say perfect you still would have problems since that hardware is not made for the software. The nexus S had the chip for processing images on super amoled be do not. This may be why our colors are different and why the vertical lines are more visible than on other super amoled devices.
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
Are you saying that the colors are off, or that they just aren't as vibrant as they should be? I find the colors to be very nice, but the vertical lines are visible on my background as well. Then again, I came from a Motorola Milestone, so any newer phone could have amazing colors compared to that :D
