[T-Mobile Samsung Galaxy S II SGH-T989] :
Colors , Saturation and contrast are off. Tmobile version galaxy s2 contrast is higher or lower than the other variants.The gpu is not processing the screen images correctly.Some models have almost no saturation at all some have to much. Certain colors produce incorrect colors though this is just a samsung's problem with saturation. I think samsung got lazy with the emulation processing for the screen. They all could be calibrated the same though. This can also be a manufacturer error when samsung seals their displays. I doubt it though. I have no idea how the MDNIe chip process images for the screen or do i know what they did to emulate the process with the qualcomm chip.

Going to call up Samsung Canada and see what they have to say about it. Probably isn't as widespread an issue(yet) seeing as the phone just got released yesterday. My fear is that I return the phone and get another one, but it might be even worse, it's like russian roulette! :eek:
[T-Mobile Samsung Galaxy S II SGH-T989] ArcticWolf91:
I posted this in the other thread about this, but since you have both OP, maybe you can try this:

I have an idea to see if this is hardware or software related.

You can use an app called terminal emulator and run the command "dmesg" (without the quotes). This will give you a long list and there you can find the panel type.

You guys can do this to both the T-Mobile and Sprint versions and check whether they have the same panel. If they do, then it's probably software, if they don't then its probably hardware.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Exactly! These are the steps needed to be taken before we jump to random conclusions. I'm hoping that this is something that an update can fix, but realistically, judging how the lines react to on-screen movement, I believe it's all hardware!
[T-Mobile Samsung Galaxy S II SGH-T989] huggosz:
i followed the instructions to the T and I had no issues the screen looks just like the sprint one, I've been reading a lot about ppl having issues with their phone's screens on here so I took my phone to a sprint store and compared them side by side and i gotta tell you the screens look exactly the same! bright colors and dark blacks! on a side note I got to play with the sprint sgs2 and just going through the menus it was lagging considerably, and it force closed a couple of apps, so in my experience our version of the sgs2 is faster, I haven't noticed any lag, even playing games like Dead space or PES2011, the phone performs like a champ.
[T-Mobile Samsung Galaxy S II SGH-T989] SAlmighty:
When you all say the screen is not properly calibrated, you mean this is software-related? :confused:
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
I have been posting this bug to this link numerous times:

https://docs.google.com/spreadsheet/...lvZ2c6MQ#gid=0

I hope everybody does the same so that Samsung realizes this problem faster.
[T-Mobile Samsung Galaxy S II SGH-T989] :
All I've been asking for is a systematic approach and means to catalog the problem. If it exists for some, it needs to be addressed but painting with such a broad brush does NOT help the situation, especially since, contrary to the OP, not all of us have this problem.

At Bestbuy this weekend I compared my screen to both the ATT and Sprint versions. While the ATT version was sharper because of its smaller size, I found that my T-Mobile version was just as colorful and well-contrasted. In fact, my screen looked better than the Sprint version. Moreover, the difference in sharpness between my phone and the ATT version was not that great and more than made up for by the T-Mobile's size.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
When you find better research into this topic than the OP, then be sure to let us know.

I'll believe it when presented with some evidence. So far all the evidence appears to support my assertion that all T-Mobile (and now it appears Telus) phones suffer from a display problem.

Based on my research so far, I find that extremely difficult to believe. Also, it is well known fact that in a brightly lit room (for example Best Buy) it would be difficult to see the display problems.

I hope you understand that it is difficult to believe the claims from your subjective testing. Anybody can come here and claim anything. If you repeat the steps listed in the original post and take pictures and share the result then you at least have something to support your claims.
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
just for reference

this is not a unique problem of the Tmo version

the international version has the problem too, but it was just identified better http://xdaforums.com/showthread.php?t=1087236 and http://xdaforums.com/showthread.php?t=1139123

there was another topic with a much more lengthy explanation as to why, and there was picture of the SGS2 taken apart to show why.

but i forgot the title of that topic at the moment

it basically those blobs and lines that you guys see ends up being the internal components of the phone

the screen is just too thin, so you are basically seeing through it, and the shadow of the stuff behind it
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Do all Super Amoled plus displays have lines and blobs? It appears so. As I mentioned in the original post, the Sprint version has the lines and the blobs too, just like the T-Mobile version. And they are visible in the slow shutter shot. But people do not see them with their naked eye, because Sprint screens are calibrated correctly with good contrast, saturation and color temperature values.

And I am of the opinion that the T-Mobile phones can be fixed by doing the same. I do not know if this can be done with a software update. I worry that each display might unique calibration values. If true then a single software update cannot fix everybody's displays. In that case, Samsung may have to release a tool that allows each user to calibrate their own display.
[T-Mobile Samsung Galaxy S II SGH-T989] manekineko:
Is it just that the T-Mobile variant is lacking the settings under Settings => Display => Display Mode?

I seem to recall that someone mentioned T-Mobile was missing the configuration app.

The difference between Standard and Movie under Display Mode on my Sprint GS2 is a pretty significant change in contrast levels.
[T-Mobile Samsung Galaxy S II SGH-T989] :
We don't have that mode due to lacking the MDNie. So Samsung emulated the process using the Qualcomm Mdp.
[T-Mobile Samsung Galaxy S II SGH-T989] SAlmighty:
THAT'S IMPOSSIBLE, BECAUSE I SAW TWO INTERNATIONAL S2'S THE OTHER DAY (MAY-JUNE BATCH) AND THEY DON'T HAVE WHAT WE ARE SEEING. IN DARK, THE SCREEN IS SHOWING NO LINES AND BLOTCHES. THIS IS PURELY A MANUFACTURING DEFECT. SEEING INTERNAL PARTS ARE JUST EXCUSES TO MISLEAD CUSTOMERS AWAY. A CLASS-ACTION LAWSUIT AGAINST SAMSUNG IS NECESSARY IN THIS CASE. PARDON THE CAPS-LOCK. I'M SURE MANY S2 OWNERS ARE AS PISSED OFF AS ME, LOL. NOW THE THE NEWER INTERNATIONAL STOCKS ARE GETTING MORE DISPLAY DEFECTS. THIS SUCKS :mad:
[T-Mobile Samsung Galaxy S II SGH-T989] kabuk1:
This makes sense, actually. I've taken apart an international SGSII at work & I seem to remember the LCD being partially transparent.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
This is not a good excuse. We know that Sprint Galaxy S II phones do not suffer from this problem.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Dude are you not trying to research some of the valid points I brought up? ..... Or have you tried the terminal emulator test that someone else suggested??? Have you tried writing samsung a registered letter requesting an explanation to this issue???
[T-Mobile Samsung Galaxy S II SGH-T989] kabuk1:
I did the terminal emulator trick but didn't see anything related to screen type. I can post the data if you want.
[T-Mobile Samsung Galaxy S II SGH-T989] tackleberry:
I'm not impressed with this phones screen. Maybe its the hype that set my standards high kinda like how ****ty iPhones are as a whole but they are so hyped up people must have it...

Size of the sg2 screen is great, but notjing else. Its not terrible but I thought my G2x was much better for whites and outdoors the g2x was great.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
The answer is No. To all of your questions. Because I consider these to be utter waste of time.

If there was any value in this work, then you or someone else would have done just that and come back to us with some useful information.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
1. When someone asks you to perform some work and are not willing to do it themselves, take it with a grain of salt. And understand that they might be sending you on a wild goose chase.

2. If you did find the display model ID in the dmesg output, it would not bring us any closer to getting our problem solved. It does not matter if the screens are different or identical. It is pretty clear that one is incorrectly calibrated.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
Correctly calibrated Super Amoled Plus screens (as seen in Sprint and AT&T phones) are actually very good.

If you have a T-Mobile/Telus Samsung Galaxy S II phone then you are likely suffering from display related calibration problems.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
Looks like AT&T is getting the Galaxy S2 Skyrocket this sunday. It has our screen and processor. Lets see if it has the same screen issue as our phone does.

Basically your saying the lines only appear on the actual device not on the computer am i right?

I'm saying that gray box only appears on my phone and not anywhere else, it's present in the actual video output as I was able to get a screenshot of it and, the rest of the unshaded video did NOT have that shade or the lines.

[T-Mobile Samsung Galaxy S II SGH-T989] ArcticWolf91:
Just so you know, the command will give you A LOT of info back, so it's hard to find the line you're looking for. You're going to want to look for a line that says "Panel Type = PANEL_ID_PYD_??????"

You can read more about it here.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Honestly its not that important to me to find out if the displays are different because the issue doesn't affect my everyday usage..... You on the other hand is very bothered by these lines, so I provided some suggestions that can help you dig a little deeper into finding out what it is. Which can help you determine correctly, based on facts, whether you feel it'll be worth keeping this phone. The test you merely did prove only that there's a inconsistency within the 3 different spec'd phones. However it doesn't prove that the one you don't like is defective because of "your" opinion. Through out the thread your asking why are your comparisons so different.... OK me and others are trying to help by throwing "possible" reasons to the inconsistencies, but I guess some of our suggestions are not tailored to what you want it to be so you don't bother....you state that the Tmo sgs2 are not properly color calibrated, which is causing the vertices ghost lines. May I ask how are you a 100% sure of this?????
[T-Mobile Samsung Galaxy S II SGH-T989] djy:
I just tested two SGH-989 phones. One you can barely make out the green stripes with no blobs, and the other clearly looks more green with varying size blobs. There is a significant difference between the two models, both dated the last week in September 2011.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
My personal experience is that some T-Mobile phones perform better than others. But I have not yet seen a T-Mobile phone that did not suffer from any of the problems identified in the tests. At the same time I have not seen any Sprint phone that did suffer from these problems.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
It is an opinion. I am not 100% sure about it.

The problems are worse on some phones. If a chip or a lack of chip was responsible, as some have suggested, then all T-Mobile phones would suffer equally. They do not. Hence my theory that it is a calibration issue.

When TVs are manufactured at a factory, one of the final process they go through, before getting shipped out, is calibration. Each individual TV has different calibration settings. This used to be much bigger deal with rear projection TVs.

Anyway, if the phone displays are manufactured and calibrated like the TVs, then it is very possible that the calibration process for T-Mobile phones was not setup correctly.
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
You are right. I tried ChainFire3D and used it to set night mode. It makes shifting screens very laggy, and even my live wallpapers have big lags in its movements.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
Ahh ok, and with that said, be careful with saying it "is" rather than saying it "possibly" may be the color calibration due to whatever findings you discover. There's people who come to xda for the best knowledge on there device. Many who are currently enjoying their sgs2 will come to this thread and be misled into thinking that something is wrong with their phone. Your analysis may be completely right, and I really would hope so because that means this issue is an easy fix. If it is what I think it might be, then it'll be to your benefit to jump ship quickly!...... Here's a link to engadget spotting your issue with nexus S http://m.engadget.com/default/artic...0/nexus-s-review/&category=classic&postPage=1 if you look closely at the picture where the editor points the issue out, you can also spot the ghost lines as well. Don't you find it baffling that samsung would continue to not color calibrate their flagship phones properly????
[T-Mobile Samsung Galaxy S II SGH-T989] Tanvirul:
you guys are not doing it right

OK you guys are DEFINITIVELY not doing this right, because i just checked with 5 different tmobile galaxy s 2, ALL OF THEM had this problem, and it may not be COMPLETELY noticable in everyday use, even tho on 2 of the devices i can clearly see some parts of the blobs, but when u see it in the darkness its kind of scary how messed up the screen actually is, it kind of looks like some residue is stuck to the other side of the screen, but yea this is actually a pretty big problem, on 4 out of the 5 galaxies i saw a ridiculous amount of these blobs......
[T-Mobile Samsung Galaxy S II SGH-T989] VICosPhi:
Wow this is so true! My wife and I have the SGS II for tmobile and my wife usually does not notice such things and she saw the vertical lines which she thought looked "pretty bad". I then downloaded that blob.jpg and compared both our SGS IIs and found 100% matching results to images uploaded by OP. This is scary to see such blobs and lines on your display, I hope Samung fixes this in ICS update.
[T-Mobile Samsung Galaxy S II SGH-T989] SAlmighty:
again, this is a hardware issue, not software,

samsung can get by with this problem and just release an update keeping all pixels on in a black screen, otherwise, if they just leave the way it is, the screen will always dim and you will see black blob sh!t and strings and lines attached. :mad:
[T-Mobile Samsung Galaxy S II SGH-T989] :
I agree that there must be some variance. Returned mine yesterday and got a new one with the same date 9/28. Tested as mentioned in op and the lines are minimal and very few blobs as compared to my other one. It's is not as visible on darker screens as my other one.
[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
I was wondering was i the only one that have a issue with the whites on the display, i get a dim greyish color.
[T-Mobile Samsung Galaxy S II SGH-T989] Monk4Life:
That's how whites look on a amoled Samsung screen.
[T-Mobile Samsung Galaxy S II SGH-T989] djy:
I am on my third phone in three days. All 3 were made 9/30 and this one has the worst display. Point your camera in a dark room at night with just a little light and the streaks and spots really stand out. Really looks like a byproduct of manufacturing or assembly and the pattern definitely varies between phones. It looks like someone cleaned or sanded one of the panels with a linear motion, and looks like a hair is trapped in there too. WTF are we seeing? How many exchanges has anyone gotten away with? :D

Not that it would matter, but has anyone tried discussing this with Samsung?
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
And you know this how?
[T-Mobile Samsung Galaxy S II SGH-T989] :
It seems like a problem in the way samsung seals displays in the other galaxy forums they have the lines as well it just isn't as visible as our screen. Which would make sense because like you said the lines vary from device to device. Some one also said the vibrant and nexus s as well had these lines. If you need to turn the brightness down on the device it would make sense that it would be a manufacturing error on their end. Since the factory/plant would most likely be in a bright room. The various testers wouldn't see the defect.
[T-Mobile Samsung Galaxy S II SGH-T989] princeasi:
The thing is, this may not be considered a defect in the eyes of samsung. Samsung may have decided to use cheaper or different material specifically for the Tmo sgs2 displays, that will always produce these lines and blob that we see. If this is the case, and cost played a big part of the decision making, then basically nothing will be done about this, as they will consider it doesn't affect the user experience under normal conditions.
[T-Mobile Samsung Galaxy S II SGH-T989] cheema:
The photos in the original post show the same things. Lines are there in Sprint handset as well. You just cannot seem them with a naked eye, unlike the T-Mobile units.

Sorry, but what you say does not add up as evidence of a hardware issue to me. How can you be certain that it is not a calibration issue that could be fixed with a software update?
[T-Mobile Samsung Galaxy S II SGH-T989] :
Well keep in mind were in still in the first batch of samsung galaxy s2 for t-mobile most likely to see a new batch would be 3-6 months depending on how fast the device is flying off shelves. Well we will know when the At&T version of our phone is released. Since its essentially our phone with lte. If It has worst or better vertical lines than our product.

Hi guys,

I am using 77.30P radio in Brazil and having problems with the signal, the carriers here are a mess, the same carrier uses from 850mhz to 2100mhz...

My question is, what basebandd (radio) can i flash which uses all those frequencies?

If someone can help me out by pointing the know frequencies for the most common radios available it would be of great help!

Thanks in advance
[Atrix 4G Q&A, Help & Troubleshooting] turl1:
All AT&T radios can use UMTS (3G) 850 and 2100 if I recall correctly.
[Atrix 4G Q&A, Help & Troubleshooting] luizffgarcia:
Do you know where can i find that information for sure?

If this issue is not related to baseband, i have to start looking somewhere else...
[Atrix 4G Q&A, Help & Troubleshooting] turl1:
Google what bands does AT&T use for 3G. But as I said, I think it's 850 and 2100.
[Atrix 4G Q&A, Help & Troubleshooting] matthew5025:
AT&T uses the 850 and 1900 bands for 3G. As for the radio version, use the one that came with your phone. The atrix supports W-CDMA 850/1900/2100 for the AT&T version but mine in addition to those listed above, supports the 900 band as printed on the box.

Pinch to zoom then double tap to fit text

without

the double tap, as Dolphin does)
[Android Apps and Games] jiyucn:
@Paul22000,

I tried both Boat(v2.3), Miren and Dolphin (v7.0). They all behave as the same. When zoom-in the page with fingers, the text will not auto-reflow. My cell phone is Android 2.3.5. It's the default design of Android.

The text will reflow when you use these browsers on Android 2.2/2.1.

Another choice, for example in Boat Browser, you can enable "Show pinch-zoom button" in preference. When zooming with the buttons, the text will reflow according to the web page scale.

Hope this could help you. :-)

SGH-T989 UVKID // Insecure

What does insecure mean?

By default, Samsung and T-Mobile have choosen to lock down the stock kernel on there Galaxy S II variant, but with this kernel you can reverse that affect.

Features

#
# ADDITIONAL_DEFAULT_PROPERTIES
#
ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.service.adb.enable=1

Once you flash this you will also gain the ability to root with Super One Click avoiding the flashing of ClockworkMod Recovery if that isn't what you want to do.

How does this benefit developers and themers?

With this modded kernel, developers, themers, and modders alike can all push to /system without having to boot into recovery meaning more time to test and less time spent rebooting.

Downloads

You can reference the second post on how to flash the kernel itself, but you can grab it from here.

This kernel was compiled with the fixed source, with a modded stock initramfs that insecured the kernel. The compression type is LZMA.

If you like my work..

and wish to donate you can buy me my very own T-Mobile Samsung Galaxy S II by using the details posted here.
