After

Oh, that looks great! Thanks for the pictures, it's easier to breath now

but there is still pink in the htc website so it is hard to say what is going on,
one HTC manager I talked to said that there is a known hardware issue, but could not be 100% sure as they would have to look at the handset,

I don't notice pink in the "after" pictures. Still, the color is much "real" (I cannot say if it's better) compared to the "before" pictures

Here is a grey background screen
so what do you think?

To me looks lovely, compared with the generic 2.1 ROM.
Can I have the background, just to compare how it looks on my phone?

Im not to sure how i can retrive the wallpaer from this phone

Hopefully a few more people could post the photo's of there unit, so we can compare with the photo's i have,
from what I can tell this might as well be a software issue, i have installed 4 diff roms, and 1 out of 4 showed they grey correctly, but with the web browser showing pink instead of grey, as well, with the display at 0 1out o4 showed grey while the rest showed purple,
hope that this helps, but if your phone always shows pink and purple hase then it is a hardware issue,

Update will soon happen

these screens remind of plasmas where the whites look grey,
i have downloaded some burn-in software to run on the desire, to see
if there is any change and i will post my findings, sometimes burn in help the colors with plasmas to but this is a AMOLED screen,

I wonder if it's not HTC implementation that cause this issue?? It would be nice to be able to disable HTC sense from a regular Rom and try it out....

that would be an idea, need to find a rom with out htc sense

I don't think it has to do with Sense, since the N1 also has this "pink tint" issue (and as we all know, it doesn't have Sense).

So then could we say it is a gpu issue or screen issue?

I would say that is something more of a driver issue...
It would be interesting to know if the people that claim almost zero pinkness are using a different driver for the display.
Wondering if it would be possible to grab the driver from those guys and put it in the general release

Can someone who does not have the pink hase please if you are able to attach your drivers

well boys this is my screen now after i installed a wallpaper

These tests are interesting. My Desire has a very slight pink tint on greys, noticeable on Gmail app for example.
It would be wonderful if it was a driver issue. Keep us posted!

Well after hours and days on the phone, HTC HeadOffice is willing to replace my unit with a new unit, Nice

[Q] Yellowish tint near bottom of the screen

I just picked up a 2013 Nexus 7 this weekend as an upgrade for my 2012 model. Seems like a solid upgrade so far but I'm bothered by one item and it's the yellowish gradient toward the bottom one or two inches of the screen. I need to tilt the device maybe 15 degrees away from me to get a more consistent color. If I rotate the device 90 degrees counter-clockwise (camera now on the left), I can still see the yellowish darkening on light screens on the right. My 2012 model has consistent color throughout. I found a number of posts regarding people complaining of about a warmer color to the 2013 screen but haven't seen anything describing the gradient I see. It's rather annoying when reading webpages or ebooks with a light background.
Anyone else see this on their Nexus? Did it improve with time?
I tried to take a couple of photos but my camera doesn't seem to be doing a good job of picking up the colors.

Common issue
I returned mine (because of it) and got a new one which had exactly the same thing.
I also checked out a friend's N7 and had the same thing.
So I guess it is a normal thing. It is hardly noticeable and only on white background.
(Most panels have some kind of uniformity issues. I checked an iPad 3 and had some other issues...)

Thanks for the feedback. This is actually driving me nuts and I'm going to take it back to see if I can get one with at least less of the effect. Mine seems to be worse than the display model in the store I saw today. If they can't give me something that's equivalent in color consistency to my 2012 Nexus 7 then I'll return it and just stick with that.

If I were you I wouldn't bother.
In the store there are other ambient factors that may trick you in believing the store's sample is batter. But it will not.
3 samples I checked are exactly the same...

My device have yellow tint to. How to fix? "Screen adjuster" and other not helped for me.

I don't believe that this is correctable with software. I ended up getting a different tablet altogether and even this 10" one has the same issue. Guessing these panels are all coming from the same manufacturer....

[Q] About those viewing angles...

Hi to all
I'm pretty new to the tablet market and I just bought the note 10.1 2014. I'm in my first 14 days where I can exchange/return my tablet and I want to make sure everything is ok with my stuff.
I've read countless online reviews before making my choice and, as you all know, one of the strongest aspect of the note 10.1 2014 is the display. Most if not everybody is praising the resolution, the colors, minimal color shifting, brightness and the viewing angles. Now, I want to make sure my understanding of lcd displays/viewing angles is good.
My tablet's display is gorgeous... when I look at it straight at it. I have the minimal light bleed on the edge which only shows on black and has 0 impact on colors which I'm ok with (all demos in stores are the same so...) As soon as I tilt the tablet though (vertically or horizontally), colors become very dull. Actually, colors do not shift but everything becomes dimmer/duller. Now, I suspect this is normal behavior from a backlit LCD but still, I keep reading reviews stating the display is gorgeous and bright even from an angle which is not 100% right for mine. I've tried to look at videos/pictures online but most people doing reviews actually setup a camera right in front of the tablet and barely move it once it's turned on so it's not helping me. So when you guys are saying the tablet's display stays vivid and colorful from every angle, are you getting the same kind of behavior my tablet has and are not talking about this because this is normal behavior for an LCD display or is my tablet's display defective?
Thank you very much in advance for your cooperation. If needed, I could take pictures.

As is typical of the Samsung displays, the viewing angle stability is great. The colors remain stable regardless of the viewing angle and we did not note any great loss in brightness.

Thank you very much for your reply. Well, I guess my tablet's screen is pretty similar to the test unit provided in the review. My definition of stable brightness and colors is pretty different from the behavior of that display But to know my screen behaves normally compared to other tablets is good to know.

Just enjoy this tablet..Don't spend hours looking for problems that arent there. This tablet is wonderful , I have had mine since December with no issues at all. I'm rooted with tons of stuff on mine. Most of the problems I have been reading about are people with way too much time on their hands. Have a beer , and love your tablet!!

Don't get me wrong here, maybe I did put too much emphasis on the display and I'm sorry about this. I love my tablet too. I'm just discovering the power of the tablet and the S-Pen, the integration is pretty amazing.
Cheers

Possible screen issue with brand-new Galaxy S4 Mini

I recently (as in yesterday) got a brand new S4 Mini SGH-i257m. It was completely unopened, still sealed. Unfortunately, I may have some sort of issue with the screen .. but I'm not entirely sure. When I'm looking at a gray or dark gray screen, there appears to be a lot of discoloration and ditherting.
It's most noticeable when looking at a solid gray colored screen, such as the background in SD Maid. It doesn't look like a solid gray at all. Even pure white screens have a "dirty", dithered tinge to it. I know it's not burn-in. And I know I don't have a dirt and grease covered screen as I just got it yesterday. Even after wiping it down with a microfibre cloth, the effect is still there.
Is this normal? Do all S4 mini screens have this effect? Should I just get used to it (I probably can't unfortunately and will have to sell it), or try and get it repaired?

Yes it's normal for amoled screens...first i thought the same thing...?if you do a color test...you don't see them...you can see them only with grey colors
P.s sorry for my English

Whites can look yellow-ish. And as I've never used anything with a better screen I couldn't compare, but to me my screen doesn't seem as bad as yours. Everything is clear enough, no grease mark looking screen... Maybe watch a couple of YouTube videos of the s4 mini to compare yours. But it doesn't sound right to me... It may not be a 720p or 1080p screen but it's still clear enough.

Help!!! S4 mini screen white
Hi,
I have a Samsung galaxy s4 mini. it was working completely fine and all of a suddenly the screen just went white. I can interact with the screen and I can hear when I'm pressing things but the screen just stays white. I've tried taking the battery out and restarting it. after the start up logo appears the screen just turns white. I can get into download mode and I can see the screen.
'
what could be the issue.

It's normal, it's due to the non-standard subpixel layout:

That's really unfortunate, as I really like everything about the S4 mini, except for the way solid colors look like a dithered mess. Maybe I'll just get used to it ..

Follow-up for anyone who cares .. I got my hands on another S4 Mini, and the problem is still present on this one, but much less noticeable. It seems the new one I got has an especially bad problem with this issue. I will see if I can get it replaced with Samsung ..

Does the nougat update fix the youtube lip sync issue?

Also does nougat allow you to calibrate the color of the screen?

Yes it fixes the sync. No unfortunately no calibration of screen just the regular two modes. I also want color control as I want to make my screen a little cooler. We can just hope for a custom kernel in the future that allows this. ElementalX dev has stated he won't make anything for the P2.

If mine would had been just a tad warmer I would have thought about doing the same. But in "vibrance" mode it's good enough (barely). I can stand it as the eye gets a little used to it.
There are ways to make it a little cooler anyway. Check the app Screen Balance. It will mess with your blacks but not very much if you keep the opacity <50%. It's a tradeoff but it can help.

Actually that's what I've been using, it makes the black looks like dark blue...
The screen just isn't that good, not sure why so many people jump on the amoled bandwagon
LCD is more color accurate, no risk of burn in, the white looks so much better and the quality of LCD is always consistent unlike amoled which varies everytime.

I completely agree with you on every point. I'm an LCD person too for the same reasons.
Though I have to say I'm happy overall with this screen because of one reason, it's the most uniform screen I've ever had including all LCD phones I've had and they are a lot. My screen is pretty much perfect i never get this lucky certainly not with Amoled.

The sync issue is fixed and I don't have any problems with the screen. For many years everybody was loving the oversaturated amoled Samsung screens, but now there are opinions that some prefer lcd. Well it's a personal preference, lcd screens have bad black color and also drain more battery regardless what you're doing on your phone.
