No this is incorrect, it's just two different screen that existed in SGS2. And it's also ridiculous to make it display blue stronger as this will only speed up the degration. 

888kb24, you can see one thing, it's true that yours is slightly yellowish that it should, but your fren one is also at the same time slightly blueish than it should(which is what most of us own). And you can compare a 2nd thing. With your fren unit, when u turn the unit even ever so slightly off angle, the whole screen will get even bluer, a strong blue tint will cover the whole screen while viewing off a straight angle. While with your yellowish screen, you should be able to off angle your unit quite some degree to get the screen to turn blue slightly only. I'm still not 100% sure so u might be able to test it out.

If it's like what I said, then it's up to u whether u want a blueish screen with serious viewing angle issue, or a slightly yellowish screen with pretty much no viewing angle issue.  The sad thing is none are perfect though

    * Lifespan: The biggest technical problem for OLEDs was the limited lifetime of the organic materials.[56]  In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology—each currently rated for about 25,000 – 40,000 hours to half brightness, depending on manufacturer and model.[57][58]  However, some manufacturers' displays aim to increase the lifespan of OLED displays, pushing their expected life past that of LCD displays by improving light outcoupling, thus achieving the same brightness at a lower drive current.[59][60] In 2007, experimental OLEDs were created which can sustain 400 cd/m2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs.[61]

    * Color balance issues: Additionally, as the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light. This differential color output change will change the color balance of the display and is much more noticeable than a decrease in overall luminance.[62] This can be partially avoided by adjusting colour balance but this may require advanced control circuits and interaction with the user, which is unacceptable for some users. In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors. More commonly, though, manufacturers optimize the size of the R, G and B subpixels to reduce the current density through the subpixel in order to equalize lifetime at full luminance. For example, a blue subpixel may be 100% larger than the green subpixel. The red subpixel may be 10% smaller than the green.

I love Go Launcher EX.
Anyone second this?

nice explaination there... are u sure of that?
but to me, my fren's looks much better, screen brighter... anybody faces the same prob?

I thought KG7 is for Brasil and maybe some countries in South America. Brasil can receive TV reception so most probably not suited to us.
You can upgrade the official KG5 or the leaked KG6

Added on August 6, 2011, 8:59 amGuys., i got some serious questions to ask. Hope somebody can help me here.
1) Still haven't receive sms from SME regarding ewarranty
    although it's more than one month already since i
    bought this phone.
2) When i checked my warranty card, it's totally blank with
    no shop stamp and no imei sticker on it.
3) I can't find the imei sticker inside the box. Most
    probably the sales person at the shop keep it. And this
    made me wonder is it normal, the shop keep the imei
    sticker and leave the ewarranty totally blank.

So is there anything that i should worried about.?

Thanks.

please get your facts right, in an amoled display the blue o-led will degrade the fastest among the other colours(you can easily google or wiki it). Which is why all oled screens are bluer than normal, so that when it degrades the loss in blue isnt so obvious, common sense, blue fastest, make blue more, so you will get more or less the same colour tones later on, and not yellow-->yellower-->dam yellow the loss of blue o-led's brightness also contributes to his loss of brightness

sure you can say u have a yellower oled unit but when the time comes and your blue oleds brightness goes down alot you'll see the big problem, its up to ur choice tho, not many ppl even know about these, but if i were u i would have exchanged it, everyone blue and ur yellow? doesnt sound right to me

Please read carefully. "In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original Please read carefully.

It's true what you said, but that is a few years ago. And actually with the life span of todays OLED it's safe to ignore the lifespan problem especially for handheld portable devices. smile.gif For example lets say OLED has stopped improving since 2007 and for our OLED nowadays we only have 62k hrs until it dies out. Lets say the OLED degration starts to get serious at around 31k hrs, you'll still have to on the screen non stop for 4 years. smile.gif

Personally I have 3 devices that are using OLED and only samsung is the one having this blueish issue despite it is the newest device. And our unit shows blue because it's adjusted like that, as for the bluetint while off angle. Im guessing it's very likely caused by the glass or coating. smile.gif

did you read the second disadvantage? read my previous post i even bold it for you  that doesnt change the fact that blue o-leds still degrades the fastest and is still the current problem. Our unit shows bluer is bcoz samsung made the s-amoled screens like that, not bcoz it's adjusted in the settings or what, it's made that way, what is shown is just an experimental oled, you actually think it's accurate? what more, we're using s-amoled+ not an experimental o-led i doubt it will have 62 hours of lifetime, if so, then samsung can go bankrupt ad  screens lightbulbds are all made to last a specific time, if light bulbs can last 100yrs then philips will go bankrupt also, there is a record where a lightbulb managed to last 82 years, then why our lightbulb half a year kong ad? samsung must have its reasond . the blue tint while off angle i also cant confirm la, its oled or its the glass la...

anyways, what i'm concern is, you shouldnt advice the dude to be happy with a yellow device, he said bought same time, maybe his unit's flawed? maybe his unit's blue oled degrades dam fast? how? ask him be happy, no way right?

Because there can be alot of other things in a light bulb that cant last 82 years. And even there is one you'll probably dont want to pay for it too.

Did you see that I advice him to be happy? I'm only suggesting he can go for either one he wants Some are happy with the yellow one while some are happy with the blue, NEITHER is defective. (Of course quality wise it's defective in both of them  ) Cheers 

hahas okok maybe i read wrong, so he shud go either one, well to me the blue is what it should be and the yellow is defective, up to him to decide ba, my assumption was, (low brightness+yelllow)=blue oled degrading a whole lot faster than normal 

Cheers, personally I've owned both units before, the yellowish does bother me, after exchange it was a blueish unit. But now the off angle annoys the hell out of me too. it's like a screen with only 5 degrees of viewing angle 

Random restart.

I never flash all is stock out of the box.

App i have :

Dolphin HD browser
Adobe Reader / Flash Player
Mega Jump
Inotia3
Angry Bird Rio

I was scrolling around the apps on the 'Application' section
Suddenly restart itself this morning and afternoon.
Im using GO Launcher Ex original launcher never downloaded others.
Tell me what wrong?
Buy RM2k for this kind of issues mcb, getting fade. RM300+ phone also this issues thats why i dump it after 2 years.
I rarely play games in a day maybe 30mins. Surfing around 1hours + round up in a day.
Tell me what happen ? otherwise i gonna send to samsung service center and kick their balls up
Previously i was using the same launcher never have such issues. Today start this problem random restart during browsing through apps and when using camera to take photo

yea mine also 5 degrees but can only notice if you're in a pure white background if not it's hard to notice unless you tilt alot la, budden the viewing angle 

after try Litening 5.0, 4.2, finally shifted to 3.2 and the battery seems good!

i've checked with my fren's blueish unit, there's no viewing angle problem... exactly like mine, just the screen better and brighter

flash back from litening 5.0 to 4.2 causing me to go to bootloop..sigh...trying to reflash again 4.2...

Or you can keep the yellower screen with wide viewing angle and use CF3D's nightmode settings to tune colour to whatever side of the spectrum you want.

Sure, if you're yellowish it means that your bluesubpixes are dying, and tuning the display blue will just make it die off faster (lol), but at least you can if you wanted to.

those were the apps previously installed b4 this kind of restart happen.

so far till now no add in new apps

Most likely it's one of your three games is the culprit.
Try uninstall all the games apps and see if the problem recurring. If everything okay, then install one game app at a time. Try playing with it. If okay then add another game app and again play it then play the new game. And so on..
But i suspect it's your Mega Jump that make havoc in your phone. :-P
