Honestly I think that this is just an issue taht can be resolved with voodoo color once supercurios gets his new phone. When I turn the brightness all the way down, the blue menu loses its blueness and looks all gray and nasty....however if I turn the brightness just one notch up, the blue color is back and the lines are less visible. I have a strong feeling that its just bad screen calibration and not a hardware issue.....after all, we are the only galaxy s 2 with a different chipset....
[T-Mobile Samsung Galaxy S II SGH-T989] ninjikiran:
my screen has a bit of a tint to it on all brightness levels, the viewing angles are atrocious, just reading a book results in maybe half the screen showing a darker tint unless viewed straight on.

My T-Mobile G2 never had these problems.

Its time for me to play phone swap with t-mobile~ which kinda annoys me. Its the only thing preventing me from really enjoying the phone.

The bloatware doesn't bother me much, although I am not a fan of touchwiz, that will be remedied when I root the phone(which I don't really like to do, but don't give me options and I have no freaken choice). Not that touchwiz is bad but the lock screen doesn't do what I need it to do. Sure it looks fancy but it doesn't show my alarm time(I use alarm clock xtreme) Removing the lockscreen feels like a cheap windows 95 program(Dragging around a static image with seemingly static numbers on it). They couldn't add a damn slider like every other phone? or even their sexy tablets.
[T-Mobile Samsung Galaxy S II SGH-T989] baluchsaab:
I have these lines on my GS2, but I've gotten use to it ;/. I must say they are not visible at all when I'm watching a HD Video, but if I watch any online streamed movies, lines are clearly visible.

Anyhow, I bought mines through Ebay, so I can't really look any where to replace it. And I'm using it on Simple Mobile.
[T-Mobile Samsung Galaxy S II SGH-T989] faifai9394:
Man I hate it, I got my first one, I can hardly see line on it. The only problem is that there is a bad/defect pixel which cannot display any red or orange. So I exchange it and now I got one with visible lines but no dead pixels...... and I did it through Retension...... so its count as phone order, I cannot go to store to change it.... Hopefully Supercurio can really help on this one.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
Alright! Finally my phone made it through the entire Samsung chain and it's being shipped back to me.

The problems they said they found (according to the repair status) don't even make sense but... (and I will confirm once the phone lands back in my hands) they listed the fix as S/W update.

Original Problem:

TECHNICAL INQUIRY - LCD / TOUCH PANEL / LED - LCD SEGMENT/LINE MISSING

Problem found:

LOCK UP DURING OPERATION (SW)

Solution:

S/W UPDATED - WAP RESET
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Reads like a factory reset to me lol.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
I have no high hopes, but at least I will have an excuse to yell at Samsung a little louder :)
[T-Mobile Samsung Galaxy S II SGH-T989] STi489:
This display issue with 0 Brightness...Could it just possibly be that at 0 brightness there is not enough voltage to power the display correctly...thus only when brightness is at 0 and not nice and bright? Dunno just a thought.
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
Everybody! We have a solution, Supercurio which develops Voodoo color for most Super Amoled screen is willing to fix our problem, there is a bouty thread for him, please read through it, & help get him a device so he can fix these horrible

issues, $5 would be good, heck even a dollar, thanks in advance.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Just keep in mind folks, this will color calibrate the device. This will more likely "Not" fix the blobs and vertical brushed looking lines that most of us see.

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
he is the master of screens, im sure he will find a way to make our screan clear & beautiful as the sprint variant.
[T-Mobile Samsung Galaxy S II SGH-T989] ninjikiran:
only bad thing is we would probably hafta root the phone, or does voodoo color work w/o root.
[T-Mobile Samsung Galaxy S II SGH-T989] shehrammajid:
99% sure that root is required...
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
No root required :)
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
he will have a free app on the market and it will do everything for us
[T-Mobile Samsung Galaxy S II SGH-T989] eight_heads:
I bought a SGSII at the sale yesterday and just tried all three test above and my screen looks fine. I don't see any lines or blobs at all. Good luck to you guys that are having problems.
[T-Mobile Samsung Galaxy S II SGH-T989] supercurio:
good to know, thanks (but please share in the dedicated HOWTO thread)
[T-Mobile Samsung Galaxy S II SGH-T989] lookitzjohnny:
whats the manufacture date on the back of the GSII box?
[T-Mobile Samsung Galaxy S II SGH-T989] X-Rayden:
on my box there is no date, only a stamp with the SGH-T989D UPC/Serial, where is the date ?

My SGS2X have the broken screen, and Best buy WOULD NOT let me exchange it, i tried to the 12th, i bouth it the 29 oct.

they say samsung need to recognise the problem
[T-Mobile Samsung Galaxy S II SGH-T989] firebane:
Telus Samsung Galaxy S2X phone.

Loaded the blobs.jpg onto my phone.. went into a pitch black room.. loaded the blobs.jpg on the darkest my phone would go and I see no blobs.. just faint vertical lines.
[T-Mobile Samsung Galaxy S II SGH-T989] naga1982:
mine has it.... :(

After reading this post, now I can see every line and blotches in a low light situation when I watch videos or browsing the web and encountering the website with grey backgrounds.... :(
[T-Mobile Samsung Galaxy S II SGH-T989] hyl4me:
do you have back your phone yet? Did they fix the vertical lines problem?
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
It's supposed to get here tomorrow. I will let you guys know if it was worth the hassle.

What I haven't mentioned before is that as part of the "repair" process, they listed a replacement (with new serial number) so I am not sure if it was replaced or just a software update. I guess, I'll know tomorrow.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
I can confirm that the phone was replaced and the lines are (thank God) gone. The serial number of the unit I received is different but I cannot confirm if the SW was also updated.

If you can handle being without your phone for 2 weeks (Samsung does it really quick but UPS 2-day service stinks) I would recommend you to deal with Samsung.:)
[T-Mobile Samsung Galaxy S II SGH-T989] :
Blobs gone too? Sorry, not sure if you had the blob issues.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
I had some "small blobs" (spots) and this one still has small blobs (I found 4 when using the screen test + front camera in a very dark room) butb absolutely no lines and as a bonus my WiFi Sharing works now (no need to freeze it or root) :)
[T-Mobile Samsung Galaxy S II SGH-T989] :
You said your phone was replaced, or was it just the screen?
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
The phone was replaced, the serial number is different.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Looks like all they did is some type of software upgrade if i'm correct sw=software

and hw would mean hardware. You can provide a dump if possible might fix all there problems wap reset has to do with the modem i believe.
[T-Mobile Samsung Galaxy S II SGH-T989] subr:
I haven't rooted the phone, as I don't want to risk it now that I am not sure what's running under the hood.

If you know a way to do it without rooting, I can give you a dump.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Open adb shell and type adb pull /system. I don't know what else you have to do. You might have to create a system folder to put that into. Someone with more k.d.lang can help please.
[T-Mobile Samsung Galaxy S II SGH-T989] :
You shouldn't need to root just need adb and usb debugging on.

install the android SDK (developers.android.com)

start CMD

type in "cd c:\PATH_TO_YOUR_SDK\tools (<-- so there's a tools folder inside the sdk folder)

on your phone: Setting -> Applications -> Developer -> USB Debug Mode (dunno how its spelled correctly)

connect your phone with your pc

let windows find your phone

back to cmd console: adb pull /system

the full system dump shall be in YOUR_SDK_FOLDER\tools\system
[T-Mobile Samsung Galaxy S II SGH-T989] :
Thanks for the assist.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Im pretty sure its the same lcd display but to be sure use supercurio previous command.

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

[T-Mobile Samsung Galaxy S II SGH-T989] :
The panels are all the same only software fix off the top of my head would be samsung either made newer updated display drivers or fixed the ones we have now.
[T-Mobile Samsung Galaxy S II SGH-T989] lookitzjohnny:
hmm. i hope t-mobile sends me a good one. I requested a warranty exchange earlier this week, and the phone is in the process of being delivered to me. if not I shall contact Samsung directly and get this problem fixed.
[T-Mobile Samsung Galaxy S II SGH-T989] :
The CsCV txt is the same with everyone if you would upload a system dump to multi upload etc.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
Interesting. I'm not familiar with this app? If it's just an apk, can't we pull it from one of those models? Or maybe it's exynos only?
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
Everyone keeps saying it's the screen, but maybe it's the fact that we have a different gpu compared to the rest of the galaxy s2 line so the gpu may be the issue not the screen.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
Just posted the same thought in the other thread. Seems like a definite possibility to me.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
I think this would explain why every tmobile galaxy s2 has this issue.
[T-Mobile Samsung Galaxy S II SGH-T989] eunkipark92:
For Contrast issue maybe when voodoo Is available for galaxy s 2 it will fix the contrast problem.for blob and vertical lines....

I'm holding off till this issue gets resolved..it looks really bad...
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
Would voodoo even work with our phones since its a different gpu? I am not sure it will if it gets created by supercurio.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
Ill be the first to say that I have no clue when it comes to gpu's and inner working of the phone. can someone explain how that would cause that?
[T-Mobile Samsung Galaxy S II SGH-T989] LP_sk8er:
Ok, I take it back. This time i went into a very dark room and i can see the issue. :eek:
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
The gpu controls the whole color field of the display. It seems to be certain colors only that show the issue. So it could be a driver issue that needs corrected on samsungs/gpu makers end.
[T-Mobile Samsung Galaxy S II SGH-T989] samomamo:
Try this
[T-Mobile Samsung Galaxy S II SGH-T989] droidsrus:
Yeah. But what i dont understand is If it isnt the screen. Wouldnt all the screens have the same look? Because some say they have a bunch of vertical lines which happened to my first gs2. But with this new one. i have none. I also noticed the colors on this one were brighter than the other. I did go thru these steps tho and noticed the blobs. But it isnt greenish tho it just looks dark gray but the blobs are there.my question is. Could these be two seperate issues? N its weird how i can only see the blobs with the grey pic. The pull down notification is grey too but i dont see any blobs.
[T-Mobile Samsung Galaxy S II SGH-T989] Jjday7:
Well in my situation I had the brushed metal look and blobs of black on the first phone. The new one is brighter but has a little bit of purple hue (this could be the way the first should have looked to begin with). The new one just has the black blobs but no brushed metal or vertical lines. Looks like the vertical lines might be getting corrected but the blobs still exist.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
No because out of the millions of the same gpus created you will not find 2 exactly alike. So each gpu will have a different output quality, but all will be very close.
[T-Mobile Samsung Galaxy S II SGH-T989] droidsrus:
Ok i see. Makes sense now. Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] talltexan:

My first gs2 has it (9/28/11) .. this morning I've replace it and just now I check it and its worse (10/04/11) ... I want to return mine and wait for a month or just get nexus s 4g but I'm thinking about the $50.00 restocking fee.... hayzzz...
[T-Mobile Samsung Galaxy S II SGH-T989] talltexan:
Call Tmo maybe they will wave the fee due to it being a faulty product.

Hehe.. I don't think so... t-mobile.. "THE T-MOBILE " I only have 2 more days... hayzzzz... I hope that they will wave the fee.

Heck I notice it with that picture even. The only thing that drives me crazy at times are those freaking ink blotches though. I hope it's gpu related and they can fix it soon.

[T-Mobile Samsung Galaxy S II SGH-T989] :
Sorry tired as hell right now Problem found:

LOCK UP DURING OPERATION (SW)

Solution:

S/W UPDATED - WAP RESET

Samsung stated here that it was a lock up during software operation most likely the drivers. Most likely like when windows freezes during an installation. Messed up the driver color calibration. Which is easy to mass produce by accident.

To be sure go into a dark room (pitch black preferably) and turn the brightness all the way down with auto adjust screen power turn off. Then use cheema blobs.jpg and upload a picture here a screen shot won't work any other phone or decent camera with flash will work.
[T-Mobile Samsung Galaxy S II SGH-T989] shehrammajid:
That is very interesting. ...do u think you can make a nandroid backup from a clean factory reset and upload it so everyone can try it out?
[T-Mobile Samsung Galaxy S II SGH-T989] :
That wouldn't work nandroid simple back up as a rom. Supercurio would probably know how to access the drivers. If he had the phone. I'm pretty sure clockwork has the display drivers still working or you wouldn't even be able to see what your choosing. when flashing. So that part wouldn't be dump in a nandroid.
[T-Mobile Samsung Galaxy S II SGH-T989] shehrammajid:
Oh yeah. ...so when u enter it in to Samsung g, what exactly did u say for the problem description? And how long was the turn around time?
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:

Hi guys what are you trying to do when dumping ROM? (/system)

The Super AMOLED Plus driver (including screen profiles) is in the Linux kernel only.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Say no more.

Read the top of the first post. It has had this information on there for the past couple of weeks.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Sorry i would need subr to extract the boot.img So I can get boot.img-ramdisk.gz and boot.img-kernel. Then i would unpackage it to see if it edited or changed anyway from original samsung source. I would think a massive hardware defect wouldn't go unnoticed. So it should be like cheema said. I have no idea if the tegra 2 version which exist are affected as well either. I'm a way from a computer now for a couple of weeks now.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Thanks for the heads up! My bad for the repetitive info!

I'm just sayin!
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
This might have been commented already, but if not here it goes... :p

So i was reading over at the Galaxy Nexus forum, and people that already have the phone are complaining about the same problem we are facing, and many people have been linking back to the BOUNTY for SC to get the problem fixed.

IMO i'm starting to guess these new SAMOLED screens being pump out, might be from the new factory they made, and those assembly lines are not calibrating the screens as well as the old factory did

just my personal opinion
[T-Mobile Samsung Galaxy S II SGH-T989] supercurio:
@AllGamer I was hoping Google did a better job with their new generation SAMOLED driver, especially since early feedback I got was quite very good!

Thanks for the pointer, I'll look over Galaxy Nexus forums as well.

Unfortunately calibrations issues are nothing new here. On first gen Super AMOLED on Galaxy S, there were already very large color response gap, some (most) with a strong "blue" balance, but also other quite red.

Nexus S were/are really terrible on calibration IMHO, especially after 2.3.4 OTA. The screen on my device can only be qualified as greenish and providing ugly color reproduction.

So.. yes there's a lot of work needing to be done here ^^
[T-Mobile Samsung Galaxy S II SGH-T989] SpydaPig:
I've gone through 4 GS2 in under 2 Weeks and I have yet to find any without the blotches and lines. This fourth one I just got today is a little better than the last 3. There are still some noticible lines but not as bad as the other ones i've got. I think I can live with it but i'm still a little disappointed on how this phone turned out. Everything had been perfect about this phone but its the lines that has been getting to me
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
In my opinion, none of those phones have decent screens, though I would probably take the Sprints over the T-mobiles.

I have an At&T Skyrocket and I have this problem, but I'm having trouble gauging as to how widespread this problem is. I'm very strongly considering exchanging my phone for an original Exynos Galaxy S2, but I found out that those phones have screen problems too (yellow line on screen, circle from suction cup).

For anyone with experience with At&T returns, tell me, is it possible to return a phone I ordered online to an authorized At&T brick and mortar store? Also, how likely are they to accept my return (I'm at less than 30 days btw)? I'm afraid that the employees will just deny the problem or say that it is normal. I wish I knew someone with a non-defective Skyrocket, as that would be solid evidence. The best I could do is show them pictures of the defective vs. non-defective model. Although for some reason, I have yet to see a picture of a non-defective screen. One person has posted one of the screen but left out the phone itself so you can't prove it's a Skyrocket.
[T-Mobile Samsung Galaxy S II SGH-T989] raizaM:
I have the very same problem.

I raised the issue to a Sales manager in T-Mobile and he double checked it with another phone in the store. Both had this most annoying and frustrating issue. However, he said that this is how this phone has been built and it is not an issue! As I asked for return of the phone (2nd day after my purchase), he refused to take it back and said there will be a $50 restocking fee.

While T-Mobile does not seem to be responsible, I wonder what can be done...

I had SGS I for 2 years and loved its screen every single day. I was so happy that I am getting SuperAMPLED "PLUS" with SGS II, but... I'm just so upset...
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
That's too bad, same thing with AT&T. They will either pretend not to see it, or say it's normal then refuse to give you a refund. I think the only thing that could be done is to start a class-action lawsuit against Samsung.

i think its a manufacturing problem really samsung have the best screens ever

[T-Mobile Samsung Galaxy S II SGH-T989] DinkinFlicka:
I've also got the same problem with a unit purchased from the T-Mobile website around November 15th. Has there been any reports of a software update fixing this?
[T-Mobile Samsung Galaxy S II SGH-T989] demonwind:
No, there haven't been any notable official updates to this phone yet. However, someone is working on an unofficial fix/workaround for this issue.
