While my E4GT isn't quite as bad as the Tmo screenshots, it is significantly worse than the Sprint shots in the original post.

Hope Sammy gives us a calibration app, or some quick fix. I love using auto-brightness and using this phone at night on high brightness is screwing up my rods and cones!
[T-Mobile Samsung Galaxy S II SGH-T989] amir88:
I have the Telus version as well and I'm going to the store where I bought the phone for an exchange. They better do it for me !!
[T-Mobile Samsung Galaxy S II SGH-T989] X-Rayden:
if a canadian get a working "calibrated" sgh-t989d, please tell us.

Mine is not calibrated, i've notice it the first day while playing a dark video!
[T-Mobile Samsung Galaxy S II SGH-T989] killer_roach:
I've noticed some minor screen issues on mine, but it's not as bad as either T-Mobile phone in the examples. Doesn't look like the Sprint phones, though... but it's a bit more uniform. Not really stressing much over it at present.
[T-Mobile Samsung Galaxy S II SGH-T989] Trevnerdio:
Then you don't have a defective screen lol that's good. I love my screen, but during normal usage I notice it. Watching videos in the dark, turning off the phone, plugging the phone in while it's off, and when I open the Bible app, wow the black splash screen looks horrendous on my phone! That's where I notice it the most.

---------- Post added at 05:20 PM ---------- Previous post was at 05:19 PM ----------

And I didn't notice how bad the front camera looked...is that a separate issue, or part of the screen issue as well?
[T-Mobile Samsung Galaxy S II SGH-T989] M49MuM.357:
I have that too. I had my first unit replaced, and now I have it again on a new one. It's sooooo annoying

This tread is on Tmo news now! Good job OP.

This phone is a BEAST!

How are you guys getting them to exchange the phone for free?? They want to charge me $20
[T-Mobile Samsung Galaxy S II SGH-T989] amir88:
well I think before getting a new phone, make sure the screen for the new phone is fine, then I guess it worth the $20 !
[T-Mobile Samsung Galaxy S II SGH-T989] aleks_:
I did this with a different black picture and it's not a problem but with the blobs jpg it shows all these ****in lines and blobs. I'm pissed
[T-Mobile Samsung Galaxy S II SGH-T989] tiguy99:
buy it from the local Tmobile store directly. That way you have 14 days to exchange it.

They exchange defects for free...any other reason = 50.00 restocking fee

I've exchanged 2 already....phone #3 is perfect
[T-Mobile Samsung Galaxy S II SGH-T989] synenergy52:
Keep this thread alive guys! We need as much media attention on this as possible as it seems T-Mobile and Samsung are ignoring us. I believe i was one of the first persons on this planet to notice the issue on launch day. I posted youtube videos, wrote gizmodo and engadget. I was looked at funny when I told the T-Mobile store about my phone problem. They replaced it with the attitude that I'm seeing things. This needs worldwide attention.

There's no way a $550 phone should be doing this!!!
[T-Mobile Samsung Galaxy S II SGH-T989] SiFuDROID:
Finally aquired a phone with fairly unnoticeable lines after the 4th exchange.
[T-Mobile Samsung Galaxy S II SGH-T989] DJ Yoshiman:
I've got to say, it looks like my phone has that screen display problem, but it's not hindering anything for me. My phone display looks fine and way better than the previous phone I had.
[T-Mobile Samsung Galaxy S II SGH-T989] tiguy99:
I went to two different stores and dealt with 611 before I got my third perfectly working Galaxy S2...

Here's my story

Bought on 10/29 @ TMO store near my house....perfect screen but dropped calls like crazy.

Exchanged it on 11/4 for phone #2 at TMO store near my job 1,5 hours /away

that phone had bad screen issue but perfect radio...never dropped calls etc.

Took it back on 11/5 to store #1 by my house only to be told I by a rep there I cannot keep exchanging phones unless I want to pay 50.00 restocking fee.

I said crap. bring me your manager you guys sold me a defective phone, no way I'm forking over 50.00 when I'm still within my 14 days. You guys are going to exchange it for me...here's my receipt

Rep tells me his boss comes in a few mins and to wait because he has the override code to not charge me the restock fee

Long story short...other guy comes in says he's low on totum pole and gives me the run around about having to come back on Monday 11/7 to exchange the phone when his boss comes into work.

I lost it...went off on them both and called 611

They offered to exhange my phone by sending me a new one in the box but I'd have to wait 4 days since it was the weekend, then return the defective one back to the store with the idiots I mentioned above....

To end the story, I went back to store #2 1.5 hours away near my job on Monday 11/7 and got my phone swapped out no problem. I showed the manager there my phone and had her cup her hands over the screen to see the problem.

I had the worst lines of all. Even the contrast and colors were off. ITs a shame I didnt' catch it or saw this thread before I swapped my first phone otherwise I would have caught the issue...

Anyway, she gave me a brand new 10/1 batch phone and had me on my way in < 5 mins.

I love that store. They are GOOD! Tmobile on Elston/Diversey in Chicago, IL has earned my business forever.

I LOVE my 3rd Galaxy S2. Its perfect & the screen doesn't have the line issue. Was it worth all this trouble to get to this point...YES.

If you are within your 14 day return periods, I suggest you all exchange your phones and make sure you check for lines & other problems before you leave the store.

Make the Tmobile employees work because that is what they are paid to do...help serve us the customer & make sure we're feeling good. DO NOT take no for an answer
[T-Mobile Samsung Galaxy S II SGH-T989] :
I made a bad choice in choosing a different store than I had been to before. We have like 3 in a 10 mile radius. I first had an amaze which I loved but then found out the soft key light bled into the screen. Exchanged it because it dropped calls and they totally took me for a fool. They called their land line and just because it sounded great they did not exchange it. I finally exchanged it 2 days later because it still dropped calls. Had to pay for $50 dollar restocking fee to get the SGS2 which I love btw. First one had horrible lines and blobs that i did not see until i found this thread. Went into exchange it and no one wants to help me. They question that I am returning phones for no reason. I finally tell the guy some bs about the phone rebooting because he doesnt believe or doesnt care about the line/blob issue. He takes 30 minutes to go into the back and get me another phone. That store here on Lancaster Road in Salem, Oregon is the worst. The manager completely ignored me and then the guy goes and tells me that this is the last exchange in the store and that I would have to call 611 for future ones. I question him on that because I thought i still had 8 days left of my buyer's remorse period. He states that because I exchange Amaze 4g for sgs2, that it uses the same period. What crack!! I am just glad that I went in when i did, or i would have had to call in.
[T-Mobile Samsung Galaxy S II SGH-T989] tiguy99:
Call 611 and complain about it. Have them document it. That's what I did :D Trust me it'll all come in handy in the near future. They're supposed to exchange your phone for you no charge if its defective & you're within your 14 day return period....
[T-Mobile Samsung Galaxy S II SGH-T989] kabuk1:
You're definitely onto something here. I just did this same test & noticed the blobs/lines only on blue & salmon.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
I went the hard way...

Since I bought it online I couldn't exchange it at the store.

I called 611 and after going through all the tech BS they said they are not allowed to exchange the phone due to the vertical lines issues.

They asked me to call Samsung, so I called them, went through the tech BS again and finally shipped them my phone.

I will let you know, when I get it back, if they fixed it or not.
[T-Mobile Samsung Galaxy S II SGH-T989] X-Rayden:

this is my SGH-T989D (telus) bought on lunch day.

[T-Mobile Samsung Galaxy S II SGH-T989] 1buprofen:
Are you still within 14 days? I also ordered online but just returned using the grace period and am going into a local store tomorrow. Btw those looking for a replacement may have better luck at a non t-mobile store. I talked to a guy at target who is on commission so he's willing to work with me to get the sale and I can look at all of his phones until I find a good one. Plus the phone is $100 less than what I originally paid for it right now with no rebates to deal with :)

Edit: just reread your post and see you sent yours off to Samsung. Hopefully they help.
[T-Mobile Samsung Galaxy S II SGH-T989] amir88:
To Telus Customers:

I went today to the shop that I bought my phone and stated the problem and exchanged for a new one right away (30-Days exchange policy).

My new phone has NO lines or blobs at all but still when I see that black picture, its still greenish and not fully black.

So for now I am happy.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
Yeah, I was still within the 14 days but honestly I wanted to avoid all the yelling at the guys on the phone (just this time) and see what Samsung can do about it.

If this works, it's probably a better option than searching through many phones until I find a good one. If not, I get to yell at Samsung LOL
[T-Mobile Samsung Galaxy S II SGH-T989] :
Glad to see the op changed the title to reflect reality instead of hysteria.
[T-Mobile Samsung Galaxy S II SGH-T989] jonathan3579:
I used the image from the OP and it showed gray but when I found a solid black image from Google it showed up solid black. I'm not sure what to make of this...
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
black should be true black, you can easily test that with "screen test" from market

but anything grey or white, at low power, it will show those marks some phones are getting

not all phones are affected, as the power level for each screen is slightly different
[T-Mobile Samsung Galaxy S II SGH-T989] jonathan3579:

[T-Mobile Samsung Galaxy S II SGH-T989] ThC23:
Unfortunately the grace period doesn't start over if you exchange the phone for a complete different phone.

I learned this back in my Vibrant days.

I had purchased the Mytouch Slide and then exchanged it for the Vibrant. I thought I had a new 14 day grace period, only to find out the day I went was the last day.

So the rep was telling the truth.

#Havingablast w/ my SGS2
[T-Mobile Samsung Galaxy S II SGH-T989] supercurio:
The lead I had doesn't work.

However, I'm interested by the result of the result of this command on your phone:

adb shell cat /sys/devices/virtual/pwm-backlight/device/*lcdtype

Please note if your screen looks alright to you or not according to the OP test, thanks :)

(I'll package it later in my screen tuning app for easier usage) − root not needed.

SMD_AMS452GP08
OCTA : M3

only 2 very faint lines at Zero brightness, otherwise it's not noticeable at all under normal usage

no blops or whatever the other guys reported

some minor colour banding, but that's due the low density, if i change to higher resolution (high density) then it goes away

they are definitely wasting the screen real state, the pixels are too far apart on the stock resolution
[T-Mobile Samsung Galaxy S II SGH-T989] tiguy99:

As explained on twitter: after some more study I believe I can fix it + allow color rendering customization, but cannot write the required driver without having a development device.

[T-Mobile Samsung Galaxy S II SGH-T989] astrolux44:
I had the noisey grainy lines really bad on my first GS2 (10/6 build) and still have them on my second (9/28 build). The 2nd isn't as bad as the first, and the noisey lines kinda give any dark color on the screen a weird brushed metal look. BUT, when you compare a dark Netflix video (Louie C.K. Standup) on the Tmo GS2 with the same video on the iPad 2 the GS2 looks TERRIBLE! The blacks in the video on the GS2 look very grey with a faint green tint. And, the video very clearly has the brushed metal effect with hundreds of long faint lines stretching across the screen.

Do I make another exchange, just deal with it, or get the Amaze 4G?

I love the phone but it's so hard to ignore screen issues, because you know, you have to look at the screen!

Terrible GPS on the GS1 that I had to wait months for them to address (not truly fixed though) and now this with the GS2? Samsung just looks like a flakey company right now. dissapointed

Supercurio you'r the best ! u really care about people who got a Samsung , and your screen tuning apps are the best . can't tell same about people who work in SAMSUNG....

i think Samsung need to pay you a Lot for your great work , and should get you in their business. they need to have a professional guy like you!
[T-Mobile Samsung Galaxy S II SGH-T989] droidsrus:
Yeah. I agree. We need a bounty thread for this man. I will def donate some doe. With all the exposure this issue has gotten its a fact that Alot of people are disappointed with this and im sure the donations would just pour in. My screen isnt as bad as others.but when it comes to greys it def shows blobs n some lines. N honestly if i drop my phone again and it breaks or for any reason i need a replacement. It would suck if the phone i get is worst with the lines and blobs than the one i have now. I sure will try to buy a different phone and it would be sad cuz i like everything else about the sgs2. Having a fix for this would def keep me with the sgs2 instead of buying a different phone. Im sure it will save people the trouble and money for anyone else having the same thoughts as me.
[T-Mobile Samsung Galaxy S II SGH-T989] mushlafa:
I'm up in Canada. I just picked up a Skyrocket last week, and started noticing this issue a day or two after I got the phone. After doing the test in the OP I realized just how bad the problem was. There is A LOT of grainyness and it almost looks green.

I'm really frustrated because the reason I chose this phone was because a buddy of mine has the Bell version (non-lte sprint version), and he let me play around with it, and I was so impressed with the screen. I heard it was coming to rogers and knew that I would pick it up. I chose the phone because I was under the impression I would be getting a phone that has a really awesome screen. Now I'm stuck with a phone that makes grays looks green.

I saw my buddy last night and ran the test with him and I was completely shocked at how much better his screen displayed the test image.

THe problem is apparent all of the time. What can I do? I feel like I've been completely tricked by Samsung who thought it would be OK to put a crappy display in my version of the S2.

I wish I could have taken some pics last night. If I see my buddy again I will definitley upload some pics.

Is there any other way to check that? im currently at work and have no access to sdk or adb.

and just to add on that with my brightness turned all the way down. with blobs.jpg loaded, my screen looked nearly black.

it was an exchange from tmobile, but underneath the battery on the tag in the SN line it has 11.09 seperated from the serial number , that could be the date but im just guessing ,all i know is i tried my hardet to test it and couldnt see anything
[T-Mobile Samsung Galaxy S II SGH-T989] lookitzjohnny:
hmmm i have 11.09 on the back of my phone too, and that's not the manufacture date. i guess the only way to tell when it was manufactured is to look on the box you do not have.. thanks anyways!

Don't know if this helps but my LED screen has a purple tint to it when its off. You can see it in certain angles of light.

Also another way to spot the screen's imperfection is by downloading a free app on market called "screen filter" set brightness to 12.5% bring up the blob jpg and check. This method doesn't require you to be an a completely dark environment.
