Pink screen syndrome

I have two HTC Desire's. One has the nicest, crispest, contrasty screen you could hope for with beautiful colours, blacks and whites.
The other has a pink cast to everything which is very noticeable when they are side by side, but still quite noticeable when viewing individually. It really detracts from the experience.
I'm thinking of returning it for a swap-out.
Has anyone else experienced this?

Could you take a picture of them side by side showing the issue? I'm getting a Desire soon probably and would be nice to know if my device will have this issue or not.
Also maybe people with just one device can relate to a picture more, because most people probably just have one Desire ;-)

I could take a picture, but I couldn't show it to you as I am a junior member here and not allowed to post urls.
The cast is only 'annoying' if you are swapping from one phone to another, as I was doing repeatedly as I set them up. In use, I am now finding that the eye adjusts well enough that the cast isnt actually a problem, soI am going to stick with these phones and not swap - I could end up with a worse one!
Colour is very subjective, and it could be that my other phone is actually slightly blue in cast, exaggerating the difference.

yes, post a pic if possible,
and make sure the brightness of both screens are the same, because sometimes if the brightness was low on the AMOLED display could generate a slight pinkish hue to the screen

no need to upload them to other sites, ... you can "attach" pictures directly from your PC to here!

Something else is going on here. The screens seem to drift in colour SLIGHTLY over time. Both are on auto-brightness, and the one which was lightly pink is now fine, and the one which was fine is now slightly blue.
Like I say, dont all overreact to this. It is slight, and you would never spot it unless you had the two machines side-by-side as I have.
It is not an issue; more of an observation. They both make my Kaiser look SO old and lacking in the screen department.

Hi,

I've posted up a pic.

Replacement HTC Desire has a washed out screen :(

The phone also feels tangibly heavier.
Think it may be a Super LCD screen rather than AMOLED (how can I check?). Overall, the screen just looks grey. I want my old AMOLED one back?!

Some things to try:
- look at the screen through a circular polarisation filter, eg. RealD glasses (no idea if this works with SLCD...)
- set brightness to maximum and display a black image in a dark room
- look really closely at the screen with a magnifier (or someone with good eyesight) to see if it's Pentile (I guess an LCD screen could be Pentile too...)
- weigh the phone on some good scales to see if it really is any heavier

I've weighed it - and it's just a bit higher than 135 grams. Even though it matches the spec listed on HTC's website, I still think my previous phone was lighter. Now to test the AMOLED screen. Hmm..

the backlight is apparent then. when i switch the phone off, it goes completely black, otherwise it's a grey colour. does that mean it is not AMOLED?

It certainly sounds like that may be the case
Would you be able to post pictures? This is bad news for anyone wanting a replacement. AMOLED was a big selling point for me.

However,
Can you read it in daylight outdoors?

If it's LCD, can I have your Desire then? I hate the Pen-Tile pixel layout...

Seems the black wallpaper in the dark test isn't a valid avenue to test if it's AMOLED (see: http://forum.xda-developers.com/showthread.php?t=725656).
Think it may be either me just imagining things - or a defective AMOLED screen.

I'm sending my Desire for repair as I have dust under my screen, I contacted HTC support worried if I may get an LCD screen and they asured me they are currently still using AMOLED displays only

tell me if my screen looks washed out to you. I'm sure my last desire, the colours were a lot more vivid.

Can't really tell if it looks washed out in a photo with nothing to compare it to, but it's definitely a Pentile matrix...

Yes, definitely Pentile. Damn.

Well to me it looks ok and very much the same as mine. I have never returned my Desire to be fixed.
My colors are very vibrant and i can see the screen on daylight (using auto-brightness).
I have noticed one thing on your photos though: your Internet icon is different from mine. Yours seems an older icon, really washed out, being gray and having the home icon. Mine looks more recent, it's a earth icon in blue (same blue as the mail or message icons) with some orbits rotating around the world...
Could this be it?

The internet icon i think is Orange's reworking (notice the orange door to the house).

I just wanted to mention, I 've had 5x different Desires and some have had a more vibrant screen to others.
Through the range of brightness from minimal to maximum I've definitely been able to see that some of the handsets are bright but seem to have very slightly less clarity, whilst others have a sharper image but loose some vividness.
I prefer the brighter / more colourful one I have now.

5 Desires. I've been through 3 so far. The first two were very similar (although the second one for some reason just felt so much lighter). This one is washed out. Going to try and phone Orange and try and see if I can have another one sent. :/

[Q] LCD Bakclight Glow

Hi
I've bought yesterday my Desire and I've noticed that in the upper middle screen part there is a small yellowish backlight glow only seen on black background. Can You tell me if there should be one or I should take it back to the shop ? This is probably the new SLCD version. I don't know is this a flaw or all of the sceens have some little glow on the black.
Thanks in advance

yellowish backlight?
is it in a dot size?
have you try different background color (red, green, blue)?

It is some kind of LCD bleeding. It looks similar to the picture attached below.
Mine is just slightly visible compared to this photo (copied from androidforums.com) but still it's the same issue. I just wanted to confirm from a SLCD Desire user if this is a typical for those diplays, or if I should take it back to the shop.

Most LCD screens bleed light to some degree, but that looks totally unacceptable to me. I'd take it back.
EDIT: Oops, should have read the full post. Well that one above is really bad, any chance of getting a picture of yours?

Yeah, I finally managed to do some photos.
The second one is with other light source (a 20W lamp). The first and third are without any lamp, high iso photos, but the first one has added brigthness in Photoshop, and third is on default. Remember these photos are on full display brightness, just to show how the screen behaves on dark, black background.

It is a slcd because it doesn't say it's amoled on the back. I just wanted to know if all slcds in Desire have this problem. I don't want to take it back just to get another device that has the same problem or even worse.

Well that's definitely SLCD... OLED (like my phone) will be pitch black when it's on a black screen, as there is no backlight on them.
Yes that is definitely a flaw. I would definitely take it back. It's unlikely you'd get another one that bad.

I've found a film on YouTube:
So it's just probably the thing with all SLCD's. Still I love the phone and since I know that I won't get a AMOLED version I'll probably keep this and just have fun with it. Thank You all for Your replies

[Q] Screen Banding and Notification LED ##With solution to notification issue##

I got my Galaxy Nexus yesterday and I love it. There's just a couple of things bugging me and wanted to see if anyone else was having the same problems and of course if anyone knew of any solutions.
1- Screen. The resolution is fantastic but i've noticed some banding in flat colours. It's most noticeable in light and mid greys. There is a strip that runs up the middle of the screen that is noticeably lighter that the rest of the display. This goes away on high screen brightness but is really quite hard to ignore at other times.
2- Notification LED. Why is there no native support for customising this in ICS!? Either I've missed it or Google have missed a trick. I got it working with an app from the market but it only worked while the apple was running in the background, if I dismissed the apple from the new task switcher... No more custom notification lights.
Anybody else having these issues?

To get the most out of your multicoloured LED you can use the Lightflow app which is available free from the market, to get this working properly on the Galaxy Nexus enable "Run in Foreground" in the general settings menu.
Thanks to jabok for spotting this setting.

Sorry to bump but I'd really like the opinion of a few other Galaxy Nexus owners, especially about the screen.
I love this phone but I am considering taking it back because of the banding on the screen, it's not noticeable until there is a flat grey in an app and then it's quite visible as a lighter band up the centre of the screen.
Is this a fault or is it to be expected on sAMOLED screens? I've only had LCD before.

Does it look anything like this or something different? http://forum.xda-developers.com/showthread.php?t=1320942
Either way there are issues with SAMOLED+ screens, there are people with the Galaxy S II and Droid Razr with screen issues too.

as far as I know, it is a common trait with Super AMOLED screens - had the same issue with my Nexus S, and with my friend's phones that have Super AMOLED screens.
The banding disappears if you have the screen at a higher brightness, so it does seem to be an issue inherent with changing the brightness/colour temp of the screen.
Also, AMOLED screens are susceptible to screen burn, which is why if you leave the screen on some white text on a black background, if you then switch to a screen with mostly grey elements you'll see a ghosted image of that text.

Seeing similar on my screen but it's not really noticeable unless the phone is on auto brightness or the lowest manual setting.
From reading other threads, sounds like the GSII has a similar problem. Looks like some people have been through a few phones before getting a "band free" unit.
You could try taking it back to a (willing) store for a swap - given the current stock levels you may have a few issues though and you may not get a unit without the banding anyway.
In terms of notification LED, wait a bit for some better third party apps to arrive. Not many (existing) phones use RGB coloured LED's or similar for notifications (Nexus One and Galaxy Nexus are the only two that quickly spring to mind) so it's possible Google didn't add support because of the limited use. ICS is in it's infancy and there's a lot of development to come (both from Google and third party dev's).

Thanks for your responses!
In some ways it's good to know it's a know issue, and in others it's a bit disappointing.
I've attached an image for you to look at, you think it's worth sending back?

No.

Personally, I'd just live with it - especially given that there's no guarantee you'd get a better model if you swapped it - hell you could end up with a worse screen!

I'm not sure it would be worth the hassle to send it back. This seems to be an issue to some degree in most SAMOLED screens. You might end up with a worse phone.
I seem to recall that many phone screens have artifacts at very low brightness settings.

This is exactly the same problem as I have. On low brightness it is visible but not on normal brightness.
I did have another nexus on order that I was going to compare it with but I decided to get an N9 instead as I don't need 2 nexus phones! I figure I can go try android beam in a phone shop lol
The question about sending it back is a tricky one - it's not visible With normal brightness so how can we be sure the replacement won't have the same problem? We can't.

yep. i have a vague banding when i look very closely.
solution ? keep my eyes more than 3 inches from the screen.
I hate it when people point out things that you have to look very hard at cos you then notice them forever more

can you confirm that with normal brigthness the problem is solved on every screen?

for the LED customisation get Light Flow from the market, works great for setting different colours for all sorts of things.

i just picked a random setting to prove/disprove the brightness thing. to be honest i REALLY have to look for these bands on auto-brightness .....
just tried 50% (still too bright in my opinion) and i still cant see banding. nor about 40%.
switched back to auto (which must be only about 20%) and they are there is i get really close and squint.
Seriously .... wouldnt let them worry you !

I have just completed a 3hr car trip using Google navigation and noticed the banding on auto resolution with it disappearing on bright vivid colours or dark/blacks. Thinking of asking phones4u to check out others for a possible swap.
When the phone was on charge i didn't notice any status light or none flashing when a txt was received. Should there be?

Tab S 8.4 Screen homogeneity issues

The reasons why I purchased a Tab S 8.4 were its awesome screen quality and high grade processor. For the later, the poor touchwiz optimization and the average gpu led to disappointing results. But well, the screen IS awesome !
Or is it ?
At first, I was truly impressed. But after some web browsing and reading e-books, something felt wrong with the colors homogeneity. On white backgrounds, the right part of the screen in portrait mode would tend towards a yellowish tone, while the left part would tend toward purple tones. Nothing obvious, but quite annoying when noticed.
After trying around with different backgrounds, it become more obvious with certain colors. The one used in settings background for example: The left side of the screen is deep blue, the right part is much lighter.. and greener.
Further investigating the issue, I figured it is most obvious when watched in the darkness and using dark colors: RBG such as R:0, G:10 , B: 20 or even R:20, G:10, B:0
Did anyone else notice similar issues ? Would you guys mind trying to create a R:0, G:10, B:20 (#000A14) background and check the result on your tab S in a low light environment ? On mine, it results in an obvious gradation from dark blue to green.

Attaching some pictures. The rendering is not the best especially in the darkness, but the issue remains clearly visible.

There is something very wrong with your screen. Return it.

I second that, that is not normal

I concur with the others, get it replaced.
AMOLED screens can fail for any number of reasons (pixel death is the main one) , if yours is showing problems get it replaced now rather than live with it and have a more serious problem later.

We've seen this yellow color issue reported by a few others. Looks like Samsung let a few diseased horses out of the barn. I concur with the others. Return it.

Thanks for your feedback, guys.
I'd like to highlight the fact this issue goes completely unnoticed in most scenarios. A friend I showed it on white background didn't notice it at all, in movies/games/pictures I don't see it at all. I only felt it while reading, and even then it was not obvious, just a persistant feeling that led me to further testing.
Only the extremely dark colors seem to be affected, and even then it's only noticeable in the darkness. I will go back to the store tomorow and exchange it for a new one, but I'm wondering if the issue isn't widespread and simply went under the radar as its effect is hardly noticeable in 99.9% of the situations.
Did anyone else check at an homogenous R:0, G:10, B:20 image in the darkness with their tab ?
I personnally used Moon+ Reader's background color settings for testing purpose, pretty easy to set up.

New Tab S, same issue
I changed my Tab S 8.4 today for a brand new one. Same test, same issue: the background is still not homogeneous. The issue is visible in the darkness on dark colors such as the one used for the settings menu, which seems naturally gradated from deep to lighter blue on my screen.
Could someone else test and reproduce the issue on their tab ?

I have tried to reproduce what you're seeing on my 10.5 and honestly I can't. I'm not going to say the white is always 100% pure white but it's close enough. At the same time I'm trying to avoid looking for something that's not there for my Tab.

Maybe you can go into Settings / Accessibility / Vision / Color Adjustments and see if your calibration is off. There is a test there where you arrange tiles by color gradation and it adjusts your screen. I am having none of the issues you mentioned, but my 10.5 Tab also passed that test with no color adjustments required. Give it a try.

Test completed successfully. The calibration is fine, and the issue is not noticeable during the test. The issue is actually not noticeable in most usages, I only see it on homogenous very dark color backgrounds (the 10% darkest colors), and while in a dark environment myself. In most common usages, the screen looks fantastic and flawless.
Unfortunately, I often use my toys in my bed in the darkness. AND I am concerned about a possible defect that would get worse over time.
That said, tests on similar colored backgrounds on other AMOLED screens (PS Vita, Galaxy SII) lead me to think this could be a global issue with AMOLED.

Dear Friend. Like you I am very sensible in that point. I have a lot behind me and I can tell you, that homogeneity is something we can not expect from all types of modern displays, except the pro ones with a special function that takes care about this issue. Any screen has such issues, the question is just what type of and the intensity differs. The lower the light in our environment the more sensible our eyes get. The longer we stare into the screen the better we see all color details. Worst case scenario is a totally darkened room. Your eyes won´t get more sensible than in such a situation. Especially AMOLED displays will show the strangest kind of irregularities you would never see normally. I remember the Tab 7.7 -- in a dark room the screen was over and over covered with black circles. Wow ! The Vita shows strange textures instead. It is horrible.
My advice to you would be to start trying to avoid using your tablet or any display in a dark room. Turn a light on, it will be nice for your brain and eyes and you will not see the described things. It´s just a matter of habit, nothing else. You will get used to it and probably feel very well with it. Anyway there will still be the green haze.... Not to talk about the yellowish etc. stuff.
I returned the Tab S for a MiPad and it´s much better, really nice homogeneity (compared to other actual devices).
I had 4-5 iPad Mini Retina and all of them have horrible yellowish/blueish tint.
I had 4 iPad Airs, 3 were horrible in a similar way, now the 4th one is okay, I finally had luck.
I had 2 Galaxy 12.2 - the first one yellowish in a quarter, the second has just a slight, short yellow stripe on the bottom border.
I had a Kindle Fire HD + HDX - both with bad, ugly green spots at borders and corners. Also partially yellowish.
Once I held a Galaxy Tab 3 in my hands that was actually flawless. I was shocked. It never happened again. Was from a classmate.
Today I guess it was a mistake since I could not test in in a home-at-night-environment.
I checked dozens of Tablets in big stores here - guess what I found ???
Look at the iMacs .... Horrible yellowish tint. Horrible. It´s a shame.

I use my Tab S 10.5 in a dark room with some regularity. I've never experienced any of these odd artifacts you guys are discussing. My black screen is just black. Colors look right. White is white. I think its a fallacy to claim that all amoled screens face these issues. The amoled screen on the Tab S is the best most advanced amoled screen ever created. Problems from older devices shouldn't apply here.
Please remember based upon other user input, Samsung did seem to have a run of defective screens on these tabs they put out.
Here's a quick video test taken in a pretty dark room (it's daytime here). As you can see the screen is just black. There is absolutely no reason to avoid viewing your Tab S in a dark room. If you are not seeing the solid black I have demonstrated in this video I suggest exchanging your possibly defective unit.

In my experience 100% of AMOLED displays exhibit this behaviour, i.e. both Tab S 8.4 I've had! The first one (exchanged because of unhappy whites) had it so obviously that it looked like a diagonal gradient fade to one corner. The second tablet shows it as a slightly patchy screen, see attached photo which looks worse than the reality.
This is only visible in a completely dark room with the display set to its darkest (or close to), displaying a very dark image (my photo is of the spec. you mentioned - hence blue/green colour). To show this I needed to use an exposure of about 1 second, if you use less the image will appear black, likewise (probably) if you try to capture it as a video using normal ISO values in camera, the camera won't pick up the background.

All I can say is that is seriously messed up. My screen looks nothing like that and just as pitch black as in my video. Considering black pixels in amoled screens are basically turned off, they should be utterly and completely black and devoid of light. Am I misunderstanding and your picture is of a blue background?
All other dark colors should be solid without strange light effects as well.

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).
Obviously under these circumstances an LCD would appear as a (relatively) bright grey !

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).

OK I'm a bit confused. The image you attached looks either black or very very dark gray on my screen. No color variation at all. Oh well

Same on my tab in daylight, it only appears patchy when in a very dark room with brightness turned right down. Maybe amongst the variations some will be perfect?
