This is why your Galaxy S8 display may be tinting red, software update to the rescue

0. phoneArena posted on 21 Apr 2017, 03:04

Experts attribute the possible reasons to a glitch in the voltage current that drives the red pixels way too high, or to crosstalk of the various subpixel colors that seeps into the reddish side of the spectrum. One former factory employee at Samsung has commented that it will be difficult to address the discoloration with a software update if it is a mishap during panel sheet production, though other experts counter that, depending on the issue, "a software update would be enough to balance out the reddish display to the extent that consumers are satisfied..."

Sure, keep giving excuses as if THAT's gonna help, greedy bastards!

Yup, at $1000 you want your device to be glitch proof. Wants the point of being premium right? When at day one you'll be greeting yourself with faults.

Except the fact that almost all screens are way too blue out of the box and no one complains. LG, HTC as well as Sony screens are often above 8500k, when it should be 6504k.

This is blown out of proportion. Now, I'm not a fan of the s8, but the screen is fine. If you get a faulty unit, fix it or get it fixed/replaced at the store.

Never saw display faults reported for LG, HTC, or Sony. IPS is too reliable to have faults.

You've probably not heard of it because display calibration and color temperature is typically not considered a fault. It's really common. Most people won't notice it unless you're looking at them side by side.

Samsung just announced that it will patch and fix the red tint problem. And still fanboys are still in denial. Smh

That actually makes your claim false. If it can be patched via software, it's not a faulty unit.

It's just a color calibration error, which is very common on displays. Samsung is getting flak for it, hence they are fixing it. If LG or Sony gets the same, they will fix it too.

Patches are meant to be fixes. Why patch something and fix it when theres nothing to mend or repair?
You've said it, they're fixing it which actually means the device is faulty.

Faulty device means the hardware is faulty. In this case, the hardware is not faulty; the calibration is.

I never said the display is perfect. It's not, since the calibration is off. But it's by no means faulty. It's just a software issue.

Bad calibration is not considered under faulty display. If it was the case, all LG, HTC and Sony devices are faulty since their color accuracy is garbage.

This is a white balance issue and hence can be fixed via software update. If it was a panel issue like dead pixels, or ghosting, the panel or device would need to be replaced.

Faulty can be software and/or hardware hence a software update is issued. And why you keep repeating mentioning other OEMs? Don't try to find fault in others to compensate for your shortfall.

Sorry "settings" but you 100% wrong about any problems with the s8 over other s phones calibration problem you get ┼Áith all phones, but why it's more clear this time is Samsung added a new setting to there software And that the red and blue and green setting edit, but they added it without an turn on or off I.e. It's just live on a setting that auto changes the image, so sometimes it's making it to red due to the calibration of the display, I.e. The update will turn them off so it will work like the s7 out of the box and you can then turn it back on if you like

I.e. The setting is used to auto make thing look good "active display"

Isn't it called "Adaptive Display" ?

Since the software doesn't know if yours has a red tint, it can't help. All software can do is alter the color balance and reduce the red. But if they do it on all the phones, some phones that are already perfect will become too blue, and this will cause the opposite issue.

The best solution is to go in settings and adjust the white balance yourselves. It isn't a defect, it's just screen calibration.

In short, Samsung Quality Control failed again. Adjusting white balance just won't do it. You'll get false color representation and reduced screen brightness, opposite from Samsung's marketing of the "infinity display".

How will fixing white balance give false color representation. This is pure BS.

Also, increasing color temperature usually increases brightness, not decreases it. Learn how displays work before spewing BS around.

Companies who learn from their mistakes like Samsung and Oneplus fix their issues, while dying companies like HTC, Sony or LG don't even add an sRGB mode in display profile.

Remember how Oneplus added sRGB mode via an update. Come back to me when you see LG or Sony do it.

RGB sliders are maxed by default, to remove the reddish tint all you can do is adjust the slider to the left therefore decreasing the screen brightness.
Want proof?

And it still doesn't change the brightness as you can see in the video.

This is not how AMOLED brightness works. The brightness depends on the PWM and the APL of the display. You are just changing the white balance, not turning off red light by doing that.

Most of the brightness comes from the high energy blue LED. Red barely has an effect on brightness. If you calibrate other OEMs displays, they will lose a lot more brightness since they will have to turn down blue light.

In fact, there was a video by Erica griffin of some Xperia phone a couple years ago. She demonstrated that fixing the white balance reduced the brightness from 600+ to 400 nits, since it was so much more blue.

The S8 amoled is different from the previous ones. Samsung claim it has Deep Red so that explains it. It's all over in XDA. Users reported adjusting RGB sliders minimally solves the problem so there's really wrong with the new amoled.

It's not defective. It just means some units have higher red than G or B and they are not calibrated for the voltage levels.

Honestly, I can't believe you still don't understand. It's an issue with the calibration, not the display.

You wrong it's because they added the red setting page without an on and off, the s7 will have been the same, but there is no setting

If they are maxed and at max everything it produces too much red, then reducing the red down by the amount that is too much will give proper colour representation.
You aren't adjusting RGB values when you do these things, you are adjusting how much voltage goes to said red led's.

So full 255 Red will still be 255 red.

This is equivalent to buying a new car and having a tire with low pressure or a slow leak. Put some air in it and deal with it or replace it. No biggie.

Hope Apple and LG not shifiting to carrpy Amoled, Super Amoled or OLED soon and stuck to IPS LCD for a while.

More gripe from picky consumers! If they say they're gonna fix or replace it be happy! I got a $150 pair of Nike that the sole came out 2 days later and couldn't return because I wore them outside! Now that's a reason to be peeved!
