[Q] White Balance of HD2 Display not Camera - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

I purchased my second HD2 and realised the display has a "Blue/Red" tint, in contrast to the former which has more of a "Green" tint.
The display on the new HD2 looks very murky compared to the old one.
My 80 year old mother with poor vision could see. The difference is evident.
If you check the color spectrum on wikipedia . org/wiki/Color
Red is between 700–635 nm and Blue is between 490–450 nm
Hence these two colors fall on the outer spectrum of the midrange unlike Green and Yellow
The midrange colors: Yellow 590–560 nm and Green 560–490 nm are closer to white, which explains why the older HD2 with a Green tint, in contrdisdinction to the new HD2 looks more brighter.
Is there anyway to adjust the white balance on the HD2 without me having to resort to the repair centre.?
If I take it to the repair centre, does this mean they will need to open the unit for tuning???

Same concern here~

Theme Background - White or Black??? [Poll + Discussion]

So, I'm curious to know, which you guys prefer - the white theme background, or the black? My first Windows Phone, the Sammy Focus, had that beautiful Super AMOLED screen, with the most awesome blacks, so there was no question. My HD7, well, it had an awful screen, but I still liked the black.
Now, with a proper white phone (really, the only solid white smartphone other than the iPhone 4/4S), I'm torn on using the white theme, or the black theme.
I'm much more fond of the black theme, because I'm used to it. Although, obviously, the white one not only suits the color scheme of the phone, but looks quite unique.
On the other hand, what about the battery? I believe the Radar has an SLCD screen, but at the expense of sounding lazy (which I am), I have done no research into the actual screen type, and whether using a black background will save battery burn.
So, which is it folks? White or black? For preference, and for battery life?
T me, I d prefer the white background. I would like to tea the batter life but so far I am pretty happy with it, specially coming from an HD2.

Black background is eating much less juice than white
White background uses less battery than black on an lcd, although the difference is negligible.
Black backgrounds use less on AMOLED whereas a white background uses considerably more.
So for you, both backgrounds will have negligible impact, but a white one technically uses less power.
I'm suing white theme for Radar 4G but I used to have black theme for my Dell Venue Pro. I like the white better than the black theme with bright neon colored case.
As for the battery consumption for SLCD which Radar 4G has, there's no difference between white and black.
For Amoled screens like on Focus or Dell Venue Pro, black drains less power because Amoled technology doesn't illuminate as much on darker colors than birght colors. Meaning very little light is emitted from the screen for darker colors, so less battery is used and shows deeper blacks and sharper contrasts.
For LCD screens, it illuminates the screen regardless of the colors being displayed. Meaning the battery consumption is the same for both black and white themed and as a result blacks look bit washed out and grey-ish because of the light compared to Amoled screens but colors are brighter and more realistic.
But really, even on Amoled screens, the difference is very little unless you have the brightness setting on max.
I use the white theme during the day and the black at night

[Q] Does your backlit buttons have yellow/green tint?

Hello all,
opened my white 920 today and I fiddled around with it for abit. I just noticed however that the backlit buttons have a very obvious yellow/green tint to it. When I compare it with full brightness white on the screen (as the buttons arent affected by it), it is very obvious.
Do you guys have something similar issue, or does your backlit buttons appear as crispy white as when you have full brightness on your screen?
yeah, i have the grey 920. the buttons are really yellow... im trying to ignore it, but if other people have pure white backlit keys, i will send it back i guess.

The only "positive" I can see about this is if you're watching the phone with tired eyes (when waking up in the morning in the dark or something) and you have low brightness but the 3 buttons are shining with the full crispy white and might hurt/annoy your eyes (unless the light can be completely turned off somehow). Yellow tint is after all more "calm" to the eyes. But other than that I guess it should be considered a defective unit.
Read though from a different user that his keys starting becoming more white after his 3 days of ownership. How long have you had the phone?
Compared full brightness to my old Desire HD, and the DHD white appears way more crisp and whiter. DHD uses super LCD. I thought this was supposed to be a top device, dafuq is this????
My black 920 does not have tinted buttons, my yellow one does. Might be an idea to add the color you are seeing this on to your posts, I am assuming the non-black versions have this ?
this'll be my second week with it. i played with a black one in store at JB, the buttons seemed pretty white. havent seen a grey one like mine in store though, so nothing to compare it to. might send an email off to nokia about it actually.

talking to a Romel via Nokia Chat right now, he has so far said there is nothing defective with my phone. but he did just ask if changing the brightness settings on the phone also changes the brightness of the capacitive buttons. for me, i actually dont see any change. how about you guys?

I have a White model. I compared full brightness with my old Desire HD. The white colors on DHD is much, much more white (white as snow) when put next to the Lumia 920 that has a slight - yet obvious - tint to it. The buttons are even more tinted.

Changing brightness for screen does not change brightness on buttons. I could live with tinted buttons for when using phone in the dark since you cant turn buttons off or lower them. But as soon as I saw the whites (on screen) on my Desire HD were far superior, I called for a replacement.
I dont know if simply the DHD has a better display, but I dont wanna roll the risk when im gonna be having this phone for the next 2 years. DHD uses Super LCD while Lumia 920 uses IPS TFT, and as far as I know IPS is supposed to be better. Either way, im hoping the replacement will be different. If the screen (not buttons) is gonna be the same on replacement, im simply gonna assume its how its supposed to be. Just kinda sad though how my 2 year old DHD is showing better, more crisp colors than the brand new Lumia 920.
I have taken three pictures with a bad digital camera that might help people tell the difference.
(sry for blurry pic 2 and 3)
Picture 1 (lumia down most)
Picture 2 (lumia on right)
Picture 3 (lumia down most)
Try look at one screen, then quickly the other, then back to the first one... Keep jumping between the two screens quickly with your eyes and you will notice the very different kind of whites the displays are showing, you can tell the Lumia is not showing as "snow white" as DHD. Might not seem like a big deal on pictures, but it is very noticeable in person and a shame for such a high end device.
Nope.. My friend has it.. and they are completely white..
Waiting for replacement. Will receive either tomorrow or monday. I will then compare the current device with the new (since I have to use the same packaging im getting with the new, to ship in the other). Will update here when I did it all.
I have a white 920 and yellow tinted buttons. I thought it was just supposed to be that way...

I think it is. The 920 has the same chrome/silver over the soft keys as the Nokia and att labels. It's a common belief that the chrome alters the color of the white leds.

Since so many wrote that they have pure white backlit keys on their devices (including white devices) I simply didnt wanna deal with it. :laugh:
Should get replacement tomorrow and I will report back.
Replacement update:
After receiving my replacement I can confirm that if you have a phone with yellow tinted buttons, your device's screen will most likely also be affected. I currently have the faulty and new device at hand, and from putting the devices side by side with full brightness while viewing a blank white page, I can easily tell the new device has a much brighter screen, the white is... way more white, while the faulty device has what seems to be a blue tint over it, and a lower brightness overall. Because of this, all colors are affected. Not only do they not stand out as much, but some brighter colors (such as yellow), will with the blue tint appear darker.
Note though, this is all with two devices side by side. Even if you have none to compare with, I can tell you the difference is very noticeable. I will recommend anyone who believe they have yellow tinted buttons, are therefore might be affected on the screen aswell, to get a replacement!
To make yellow tinted buttons most obvious, put your device on full brightness and go to a white blank page! Now look at your buttons and compare its "whiteness" to whats on the screen!
Note: The buttons will never be as bright and white as the screen. A non-faulty device will have a dark-layered-white (or they would sting your eyes when you used low brightness), while a faulty will have a most obvious yellow tint to it!
If anyone has any questions or something they want comparing from the two devices I have (up to 4 more days), please let me know.
3 Buttons - 3 colors ...

I received my 920 last Saturday. My 920 looks fine. Right now i notice the color stuff - or the "maybe" color stuff ...
The arrow on the left looks nearly white.
The windows symbol in the middle looks white (a touch of light green/yellow?).
The magnifier on the right looks nearly white.
Any idea?
Thx, SP

What do you mean "nearly white"? A non-faulty device's buttons will be a darker tint of white (never as white and bright as on the screen). Do you know how cars sometimes has tinted windows you cant see through? Imagine the glass layer below over the buttons is tinted as such, making sure the light does not come through as strong, but remain white.
In regard to telling if it is faulty, all I can recommend is to turn brightness to full, make the theme white and then compare. Just keep looking back and forth on the screen and the buttons, you will indeed notice if they have a yellow tint to them, but im not sure with "nearly white".
Can you maybe go to a store and compare with a display model?
In the end its up to you if you wanna go for a replacement. If they're offering a free replacement you can take use of it, and if its the same, you can always ship the new device back (unless you're keen on the new one incase your current has scratches or whatever)
White seems not to be white...

Thanks for your reply! I compared with a display model and your right! White seems not to be white on my 920. My Lumia looks like there is dust in the display... It is pin sharp - but black is a bit grey - white is not full white. All the colors seems to be a bit "overlain by" a blue film...
I did not recognized it before - cos i did not compare the display with a different model...

Good to know you could compare and identify the issue. I hope you will get a replacement. Know though that I recieved 2 phones with this issue. Im not sure if Nokia shipped out a batch of faulty devices, or if they're using different suppliers for their screens. Either way, you shouldnt ship your first phone back until you get the second, so that you can compare them and make sure the new isnt faulty/"from-a-bad-batch".
Well for me the white on the screen is totally white, no worries there but on the touch keys I can see a shade of yellowish tint on them
I put the display on full brightness and checked this...I have white lumia 920 model RM-821
The screen brightness and white levels are unrelated to the yellow tint on the buttons. I have a flawless phone and yellow buttons.
All new batches are having tinted buttons ( yellowish~green ). It was done on purpose to avoid disturbance at night because they do not dim when the screen adjusts itself to a lower level of brightness and that could potentially annoy you when the screen is set to low brightness at night.
It's how the phone is supposed to work. Now please don't go exchange your device if you have the so called " perfectly white buttons " for a tinted one. There are other things to worry about in a phone.

If I only look at a faulty device, the white also appears... white. First when you have them side-by-side do you realize it. You would need to compare in a store like someone else did in this thread I believe, and he got a confirm on a faulty device.

No, I wont exchange. Like I mentioned I do not mind the yellow tinted buttons. I would prefer the white ones, but I cant go on exchanging every second/third day.
Thanks for the info though.

Anyone have a Yellow tint display?

I've noticed that my screen is rather yellow than my iPad or Xperia Z3C. Does anyone else have a yellow tint on their display?
In response to my dissatisfaction with the nexus 9's quality control (ie. light bleed issues) I've gone through 5-6 devices by means of in store exchanges, most of which have been 32 GB models. One device in specific, a 32GB White, i noted as having particularly noticeable yellow hue's. I had it for about 20 minutes before swapping, and compared it next to another device. Not only did the screen seem yellowed, but the displays output seemed to have diminished image quality when comparing to another N9 W32. I'm curious if this device has screen from multiple sources...

Several comments about this in the General thread. People are seeing with and without yellow tint.
EDIT:
I just tried my first N9 (white 32GB, October build) and yellow tint is on it--it looks "dull" next to my N7 FHD. It's going back due to a bent frame, but the tint would make me return it. I'll try one more.

[Q] S3 Yellow tint

I've bought new galaxy s3 and i have this problem. When looking straight on it has yellowish tint, when i tilt the phone just a little bit in any direction yellow becomes white and it looks normal. I never had amoled phone before so I don't know if this is normal.
I already saw phones with greenish tint
My mother's S III mini is like this...
It's the problem for AMOLED screens, you can end up buying one of them that lacks color accuracy and mostly it can be noticed on the tiles of android 4.1.2 from Samsung!!!

Display, dull colors and white=gray

Is this common?
The G5 I got the white is gray\yellow compare to a cheaper Chinese phone.
My LG G5 is on the right, to the left its a cheaper phone form China.
Is this normal or do I have to send it in for repair, I just got it.
Guys... real white feels yellow tinted to a "newbie" eye. I noticed it 3 years ago when i bought a < 1 gamma calibrated monitor for my computer. You may prefer lack of this yellow tint nevertheless it is the true white
