Hi,
Ok first of all i know that there are other threads related to this thing, those threads defined the problem and many posts were speculations and wondering wither its hardware/software/glitch .... etc
As i was searching about this and saw the other members conclusions I wanted to start a new thread so any new member comes and read this and know exactly why is this happening to him/her, and wither its a real problem or not.
Desire's AMOLED displays have a big resolution 480*800 pixels,and have different sub-pixels arrangement in it, each pixel have "RedGreen" and the one after it is "BlueGreen" .... RG BG RG BG, .. etc, that is PenTile Matrix, while other LCD and "normal" displays have RGB RGB RGB, ... etc
for more info about this, click here
the pentile matrix looks exactly like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now the effect of this matrix is double edged, instead of having 3 sub-pixels in each pixel, we have 2 sub-pixels in each pixel, this saves power, precious battery power, but also this arrangement of sub pixels contributes to the issue somehow because the colors will not "look" exactly the way they are (the way the RGB matrix show it, which is used in most of our displays like TV, PC, LAPTOP, ... etc), there will be slight difference due to the screen "approximation", and that difference is NOT noticeable in most cases, only in few cases where the solid colors intersects with each other.
see the posted screenshot of Gmail app with the gradient color near it
see how the color picker identified the gray color, .. and how close it is to the pink, the pink showed due to the display approximation of the color.
and most importantly see how "photohop" saw the color as "not a web safe color" and see how it showed in the small square the pink color!
photoshop detects this because it knows that if an "approximation" happens than this will be displayed as pink.
And not only that, photoshop suggests that you put a "safe" color, and it shows "pink" instead of the gray as a suggestion!! why is that?
To find the answer, look at the circle in the color gradient board, you will see that this "gray" is nearer to the pink than it is to the actual gray!!!
and here we are seeing it pink on the Desire's AMOLED devices, what a surprise!
Now notice how the upper bar is dead gray, and does not have any pink in it, that is because its "GRAY" is not close or near any other visually-different color. and of course photoshop identified it as "SAFE for web", and that even if an approximation happens, this will still be rendered as gray
the good news is, it will NOT be noticeable in most of the cases, because most of the colors are not gray scaled and not "visually close to the human eye" to other colors, as you can see from the gradient color posted there are many "safe" grays out there, ... but google had to choose that gray that is near the pink
Now the bad news is, that this is NOT an android software problem, it is a hardware (display/calibration) issue.
but does that mean it cannot be solved "indirectly" by software? .... not sure, am thinking of what if Android created a layer where it picks each color and see wither its safe or not, .. if its not safe than do an OS approximation for that color, if its "gray near pink" change it to "gray" and pass it to the AMOLED as "safe color". not sure how that would be implemented or what is the weight and impact.
but as i mentioned before, if apps stick to "safe" colors, this will insure that even if an approximation happened, nothing will be noticeable
------------
UPDATE For people who think that the issue is from the browser and not from the AMOLED display that has PenTile matrix.
here is a screenshot from Android SDK emulator with the same browser as in Desire (WebKit)
here is a screen shot of the original website from the PC, using Google Chrome browser
and here is a screenshot of the site taken directly from HTC Desire (the site has been visited from the HTC Desire and a screenshot was taken and transfered)
Its pretty clear that the browser is not the real issue (even though it has some slight very slight pinkish hue), the pinkish is alot worst in the desire than what is the emulator and the screenshots show
-------------
UPDATE
After seeing the below pictures (thanx onkolog for posting those pics!), one can conclude that this "gray shades to strong pinkishness" issue is definitly not a general AMOLED issue.
People reported that in Samsung Galaxy, and Legend (Both AMOLED but not PenTile matrix) have slight pink viewing the htc.com site, but it is nowhere as pink as found in the HTC Desire
HTC Desire:
HTC Legend
as the pictures shows clearly that the legend (which has AMOLED display with normal RGB implementation) shows the Gray as pretty Gray (not as pink as the Desire).
here is a pic of the Desire & Legend side-by-side with the HTC website shown
(thank you ohyeahar for this shoot). the Desire has more pinkishness than the legend, the legend seems fine but some people said that it also has some slight pink (not as desire though)
as you can from the photo and as ohyeahar stated (having both devices, legend and desire) that its not a real issue, but its there if you really look for troubles you will find it, otherwise normally you wouldnt be annoyed from it
EDIT: some people have pink hue all over the screen, not only particular apps/colors, .. IMO this just your device, and you should replace your device
EDIT: I used web-safe colours as a technique to show how the colours might look different due to screen approximation the web-safe colours is not designed to detect the approximation of the Desire's AMOLED accurately, it is designed for web approximation due to compression, but they are similar some how, in terms of that colours are getting approximated and changed sometimes to the nearest possible colour thats why i used it.
the "web-safe" approximation only appears when an image is compressed for web standards (or approximated in case of the Desire's AMOLED), .. some images are not compressed for web use, you see the the HTC.com page gray on your monitor, and i see it gray on my nokia e75, but it looks pink in the Desire's AMOLED because the display of the desire (and i suspect android too) approximate the colour, and i used the web-safe colour technique to detect that (even though that this technique is not dedicated to identify the Desire's AMOLED approximation)
Thanks irkan for that. That goes a long way to explaining why we're getting this pink tint in the same screen when we can also see pure grey.
So, now, what can I/we do ... should we replace our Desires for new ones or not? I suppose there is no harm, just the inconvenience of setting it up again ...

as i mentioned in the last line, if you see those damn pink tints every where, than most probably your device is faulty, but if you only see them in GMail app and some few other occasions, than its just the display.
but you know what, if you still feel unsatisfied just go and replace it, setting up a new phone is a pleasure with the desire
It is quite disappointed ... I meant, the AMOLED and Pentile Matrix are suppose to improve battery life, but in fact the HTC Desire battery life is not that good.
Sure, it is not terrible. However, it is not satisfactory when you read from users testimony here:

And I hate seeing that pinkish color
Oh well, my first Android device ...
The battery drain from the screen is somewhat dependant on what you are watching. If you are displaying an image with lots of different colors, areas with black and so on, the screen will not use as much power as an LCD-screen. But if you for instance use a spreadsheat in excel or word-doc. where most of the screen is bright white, then the screen will use more power than an LCD, since it has to light up all pixels, whereas the LCD only has a few backlights.
As an exampel from a QVGA screen; black text on a white background would eat up 3W, white text on a black background would only use 0,7W.
So in real life, there might not be that much gain in powersaving.
Given that the HD2 has a 12% smaller battery and 35% more screen area than the Desire but similar battery life, I don't understand why the Desire needs an AMOLED screen that can't accurately reproduce some colours and doesn't have a true 800 x 480 resolution (more like 392*653 if you read the article linked in the first post).
seriously am i the only one that doesnt see a big difference here? i can hardly see the pink tinting. maybe if i look dead close to it i may see it but as long as its not soo obvious i wont be replacing my device.
nip picking springs to mind but anyways OP thanks for the information though.
I've just canceled my pre-order, no way I'm getting a device with a screen that distorts the colors.
This reminded me of the nexus one screen analysis made by Display Mate.

Have you tried visiting for example the htc.com homepage. As said in another post it looks like a totally different site.. Everything on it is pretty much pink! lol.

Yes i tried and it looks better on my desire actually. the colours are more warmer and sharper then on my TN dell pc monitor.
it is a tiny bit pink on the desire but its hard to tell because generaly TN panels are NOT accurate reproduction of the true colours.
matter of fact, OP did you try viewing that screen shot on a IPS panel monitor?
You guys do know TN panels do not reproduce accurate colours right lads? compare it to a ips panel and i bet you it is the same colour reproduction as the desire.
before slagging off the desire for having tinting issues, check it first. go to a apple store and use there mac to browse the htc website and see for yourselfs
Not slagging off.. Just want to make sure it is correct before I except it.. When i say it is pink i mean not far off the pink of this smilie . It isnt a faint pink which you can just pick out... It is pink.

yes it does, ... if you had TFT screen instead of AMOLED the battery life would have been ALOT worst!
and all those people you are talking about had their handsets for less than a week, ... they have to play with it every god damn minute because its a new toy, .. after the novelty effects wears out, .... am sure the Desire will last more than one day easily ..
I got a GPad yesterday and noticed a thin blue line that appears on the right side of the screen when I have been using it for a while (about 20-30 minutes or so). I returned the first and got another one today and it is the same line in same place after using it for the same amount of time. It does go away if I turn the tablet off for a few minutes. I really like the GPad and don't want to keep returning if it is a common issue. Is anyone else experiencing this?
We have two G Pad's in our house and they both have the blue line. Other than that though, the screens have excellent uniformity and color.

Thanks for your quick response Warp11. I did not want to keep returning it if others have the same issue. It isn't necessarily bothersome and turing off the pad is a quick fix.
Same issue here. It's actually to the point that I can't see it or it fixed itself.
Same issue over here,
get blue line on the right side of the screen, but it seem's to appear only when it's hot.
and also some white light bleeding on te bottom, but that's not really a problem
Contacted LG to ask if that's a known issue, but no feedback yet.
Same here, blue line on the right side when tablet in load (gaming and stuff), and mild light bleeding in the upper left corner, visible only on black background at low backlight.
has anyone who has had the tablet for a while NEVER seen the blue line? I wonder if this is a problem with 100% of the units.

I tried two from Best Buy the 2nd also had the blue line also after about 20 minutes of use. I also wonder if they all have this issue? I only notice it on mine when I play a movie with the video player app.
Hello guys...
I did some tests and I have also the blue line thing after 23 minutes watching full HD video from YouTube.
Then something else came in my mind. A simple but hard to think, to take a screenshot at the time was playing the video in portrait mode.
And guess what. The blue line doesn't appear in the screenshot (try it for yourself by taking a screenshot at the time you notice the blue line, transfer the screenshot to your pc and zoom in as much as you want - the blue line isn't there). This prooves to me that the problem of the blue line is just OUTSIDE the screen and NOT on the screen.
So if something happens it happens at point the display ends and OUTSIDE of it.
I don't know if this issue will cause problems in screen itself in the near future, but I think is a step now we know the blue screen isn't on the screen.

Has anyone else here written LG and gotten a response?
lol this just goes to show how much LG cares about this device. Sounds like every unit has this issue with the screen and they say it's "not a known issue". Sounds like people with the G Pad either need to live with the blue line or take it back b/c I doubt they can fix it. I know the line itself is really thin and hard to see, but I wouldn't be able to live with it and it also makes me concerned that there could be other issues related to heat over time.
LG G pad
Well, hello everybody! I own a g pad too and i finally figured out how to expose this hidden "ability: of the device..
I run icestorm benchmark about 5 time on a row and then i took a screenshot with my note 3 in a 90% dark room...Tomorrow i am going to contact LG for this issue too...Feel free to use the photos as you want.

Its most likely a design issue. Which I don't think they can fix it without recalling every LG G Pad.
Its not REALLY that bad, slightly noticeable when watching a video in letter box (when the background is black), but it isn't super bright so it won't really annoy you.
If you play games most of the time, you won't even notice it because as long as there is some color going through those pixels, you don't see the blue line.
The blue line is super thin, its like a line of pixels at around 1 inch long. And since this screen is super high res, the line is super thin.

Guys i took the black version after DOA (the white one)..The problem is worse! The blue line is across the whole screen even if my tablet is cold...If i push it the blue line becomes brighter and guess what...I cannt put the brightness at 100% bacause "the device is overheated"...I have to get this for DOA again cause today is the last day of 7...
Lg hellas told me to get it for DOA but they didnt have ane other issue like this before..I send them the pictures and they couldn't believe their eyes..
Anyway, sorry for my bad english..i hope LG will do something asap..and for me?? I ia gonna try to take refund and not another pad again..When the new revision come out i see what i'll do because this tablet is the best VFM out there...High end with mid end price.
Guys if you remember the heating problem is Qualcomm 600's issue. F.e. galaxy s4 also had it and it fixed through software update.
Mine doesn't overheated at all after 40 minutes watching full HD mkv movie, or after 1 hour browsing. But I also have the blue line. I have the blue line without freaking any heat in back. So I think blue line thing is in all devices, but some users just haven't noticed.
The overheating think, I believe it's only in some devices and not to all.

So for the people in here who have noticed the blue line, are you keeping your GPad? I really enjoy mine but would like some input from others to see what you all are doing/planning to do as far as return, exchange or keep.

This is my experience as well mine does not get hot at all but I do get the blue line.
I just received my LG G Pad 8.3 from Newegg last night. So far, it's been a great experience. Looks good. I bought a Tab 3 8.0 during a sale at Staples last week, but when I saw the Cyber Monday deal on new egg, I jumped on it.
My question is this : After running a few processor oriented programs ( Antutu stability, etc ) , when I open up a browser tab ( white background or something similar ) I notice a yellow thin line (not a single line, however.. its a little thick) at the top end of the screen ( towards the front camera ). It is much more visible when I use the tablet in landscape mode ( when the screen rotates - and the tint shows up on the left hand side of the tablet ).
Is this normal? I can feel the heat under the screen (it is warm under the tint area) but, the tint is visible and its noticeably yellow. I do not see the blue line as some of you have mentioned on the forums.
I am not sure if this is much of an issue, to require a return. But, I just want to make sure I don't have a tablet which has a screen issue. I noticed it last night while using it after an hour of use, so I think it's visible for the most part (because someone else did not mention it to me )
Does anybody else have this issue ?
Also, compared to the Tab 3 screen, the screen has almost a 30% decrease in brightness. E.g The tab 3 at 50% is equal to the screen brightness of the LG pad at 80%. Lastly, the screen does seem to be pretty warm (color K) in comparison to the Tab 3. I don't know if that is necessarily a bad thing, but I did notice that while doing a side by side comparison of the two tablets.
Any info on the above issue would be greatly appreciated :laugh:

Unfortunately, due to my account being new, xda does not allow me to upload links or images. I've searched around the internet and I've read a couple of posts where people say that once the adhesive or "some other material " eases out on the screen, the tint slowly goes away (possibly a week or so) It is noticeably yellowish (color wise) in comparison to my Galaxy Tab 3. I'll keep on using it for the next week or so and see if the problem persists or declines.
I'll post pictures once my account reaches the link-free level. :good:

I don't see it either.
RMA'ed the device through NewEgg for a replacement. The screen looked very yellowish in comparison to some review videos (posted on youtube). In addition, I wasn't able to ignore the yellow line on the screen while viewing it on white backgrounds.
I'm disappointed with the brightness and color reproduction compared to my Tab 3 8.0, but since I paid a fair price for it (249),I'm keeping the device. I'm hoping the replacement device will be better than the first unit I received through NewEgg. I've read several varying posts on the screen. It seems to me that there are units with an overall yellowish tint on them, whereas others do not have this issue. My desktop monitor (HP zr24w) has pretty good color reproduction, and in comparing my unit to the unit being reviewed on screen, my device had a much much warmer screen overall.
It was very similar to running Flux on my desktop at 3800k. None of the reviews not mention anything about the screen being so warm. Once I receive a replacement, I'll update the thread. If the problem is isolated to certain devices, I'd advise a replacement or return.
Looks like I have the same problem with my G Pad. I have a yellow patch at the top left of the screen and bottom right also.
Seems to come and go depending on usage, so I assume it's heat related?

The photo makes things look vastly worse than the way the human eye perceives the difference, but there is no denying that the cast is significant.

I only had a quick glance at this thread but I too get a yellow tint in the top part of the screen when the tab gets a bit warmer.
Within ten minutes of watching full hd mkv the brightness also throttles down.

Appears to be quite a common issue. Returned my 4th lg pad today for this reason.
Will be gunning for the sammy 8.4...
Great idea by LG, very poor execution
4th one?????
That's just crazy and a shame because else the tab is really nice.
Ok...
I think the "yellow tint" may have something to do with the adhesive. Quite sure the Display is glued to the digitizer. I had may tab on and stressed for a few hours. You can see the discoloration on almost any background. Even black, just couldn't capture it in a photo.
Has anyone had the tint go away after some time?
This is the same tab after sitting in the fridge for around 5 minutes...
I would hence say it is a hardware issue and not software or kernel related as some suggest.

In your experience, does it go away with time?
I really loved the tab save for that bit...But if it stays like that forever, well...
It definately seems temperature related. As soon as the tab gets warmer the blotch/tint appears. When the tab cools down it goes away.
I don't know if it is some residual adhesive that has not dried/hardened out during manufacturing.
I still have a few days where I can just give it back, so I will be looking into it.

Good luck mate
Such a beautiful device giving us so many problems...4 LGs. I don't think I have it in me to go for a 5th one..
Such a nice tab ruined by the screen. Never ever LG again. Unfortunately bought of private seller who didn't keep receipt (new and sealed) and lg doesn't stand behind their product.
From my experience: HTC - yes, Apple - yes, Samsung - yes, LG - warranty not transferable.
Avoid like a plague.

There is somebody working on that fix for your version now. Probably know something more in a week or so.
That would be nice but still won't be buying LG product again if they don't change their policy of transferring warranty to another end - user as other companies does.
As it looks like a batch of defective units they should respect warranty repair of product that has just been introduced and is well within 2 years warranty

Mine also has that line. Its not as noticeable as your picture. I did return another one due to the same line. The previous tab had once turned on. It didn't have to be running foe a long time.

There is a small spot in my G pad's screen where it's always bright. It's visible when the tablet is tilted on a certain angle. I've read several complaints regarding the G Pad's screen -- yellowish tint, thin blue line. Are you guys also experiencing the same problem?

No, but I have the really yellowish screen issue like most people here. It's really bad. Look at your whites and you'll see it.

Looks kinda like a "stuck" pixel (as opposed to a dead one, which would be black)
Yeah mine is yellowish too. It's really disappointing. I love the G pad tablet but the screen quality is just horrible.

It is really odd because it seems to be a software issue and not hardware... Mine is fixed with a quick tweak and it now looks fantastic. I wonder if I flash your kernel on my G pad if it will be fixed? Maybe they have multiple models or something... The tweak causes a lot of lag so it would be nice to have it stock. I don't want to go through the process of returning my G pad for a software issue.
Could you take a photo of your whites compared to another phone or tab like the G2. I want to make sure it is not a personal preference issue. For example I may see white as cool(more blueish than yellow) so if it is too warm I hate it, and you may like it warm but hate cool. Btw the app I use is called color test, just swipe until the white test)

I never had the blue line issue until i switched to the non-LG ROMs. I also seem to have lost the yellow tint since I switched.
It's quite hit an miss, indeed!

I have it as well, little imperfection. Must be common?

I had the same bright spot on my first one, took it back to BB and got another, it was fine. Someone told me it was caused by pressure on the back of the display.

I have a bright spot just like that on my GPad as well. The spot on mine is in the bottom left though. I also have the blue line issue many people are talking about. It shows up at higher brightness more easily and begins after 20-30 mins of use. I could live with the blue line, but this bright spot may be more than I can take. I feel like for this kind of money a product shouldn't have any defects. And I've already RMA'd the tablet once to NewEgg because I thought it was defective the sound quality on the speakers was so bad. The new one sounds even worse, I think the speakers are just rubbish. Now I'm thinking about just returning the tablet for a refund. It's a shame because it really is the best non 10" tablet right now. 7" is too small to be usable. It's fast, its the perfect size, and I like some of the LG customizations, apps, and keyboard. I also liked the price ($250 during NewEgg cyber monday). LG seems to have a serious quality control issue on these tablets. The bright spot is unacceptable and appears to only affect some units. The blue line seems to affect all of them. If I was one of the lucky SOBs who scored it for NewEgg's thanksgiving night sale for $175 I might just live with the defects. But these issues at the price I paid make me want to return it. I may wait for a next generation Note 8.

I got my g pad today and can unfortunately confirm most screen issues.
The yellow tint shows up as soon as the tab warms up. Just for fun I put the tab in the fridge for a few minutes and the yellow tint disappeared.
Could it be some adhesive that didn't have enough time to dry out?

The yellow tint can be removed when using screen adjuster. Just turn up blue colour and the tint is more or less gone. App has to run the whole time though. Still waiting for a kernel to support gamma correction....
I don't think it can be removed and believe it is a hardware issue.
Take a look here http://forum.xda-developers.com/showthread.php?t=2556691&page=2
The warmer my tab gets, the bigger the blotch gets. With software you are probably just adjusting some settings to make it less visible. I think apple had a similar issue once.
Edit:
I just had the tab in the fridge for 5 minutes and the tint is gone. So it is definately a hardware issue. The screen is back to normal.
Hi, I've noticed that my screen seems to have a warmer color tone to it, along with an slight overall yellow tint. You can see it best on light gray colors. I also had an AT&T model for a few days (returned) and that phone had a cooler, overall blue tint to it. You could really see the difference with the phones side by side. I've talked to friends with a AT&T and a Verizon version, they said their screens have the cooler toned blue tint.
So what tint is your screen, if any?
I'm wondering, maybe Tmobile just calibrates their screens for the warmer look... or is there something wrong with mine? Thanks.

Yes, but what was the screen tone before you did that?
OK... no one here today? lol
So I just went to T-Mobile store to compare, side by side... The screens are their demo phones actually looked worse than mine, almost a green tone to them and not nearly as bright. One thing for sure, they did not have the blueish tint to them, was more of a green/yellow. I'm beginning to think that since every carrier seems to have messed around with the software so much, they probably also adjusted the screen calibrations as well. I'm going to check at the Verizon store and another T-Mobile just to verify
Mine is t-mobile and bright white.. The nexus 5 had the same issue, 2 different screen manufacturers one with a warmer almost yellow screen and the other blue cooler feel.. I've been lucky with both my nexus 5 and g3 both are bright white screens and no yellow. You could try swapping it and hope you get a better screen.
Why with every new phone release this topic comes up? We know every screen's not made the same, some is warm some are cool.

Because when people pay $600+ for a new phone that's main feature is the screen, they want to make sure nothing is wrong with theirs.
Long story short, went to my T-Mobile store to compare to display models and possibly do an exchange. Compared side by side, trying out different stock wallpapers at 100% brightness. The two display models they had were also yellowish, but noticeably much more dim. Compared to an employee's phone, his was also yellowish and very dim. My phone looked good compared to all those!
Stopped by a 3rd party T-Mobile store on way home to see their display model. Not yellow at all, it had the cooler blue tone, but also much dimmer than my phone. Decided to go to the store where I originally purchased mine and compare to those... Both display models had the blueish tone, as well as the manager's phone - however, mine was still much brighter than all. So was going to exchange and we opened the new box... That phone was even more yellowish than mine and also much dimmer. Opened another one, just as bad! Those were the last two they had in stock, so they arranged for me to go to another store and try again.
Got to the other store, they got a new phone out for me - same yellowish tone and dimmer than mine. I didn't want to make them open every phone again, so I kept my original phone and left. The manager thinks they may have gotten an "off" batch maybe, and if that were the case, then every store in the area would have phones from this batch. He suggested that I come back in about a week when they get a new shipment, perhaps from a different batch, and try again.
So... out of 10 T-Mobile phones that I saw today:
- 4 had cooler blueish tone screens
- 6 had warmer yellowish tone screens
- My phone was brighter than all of them!
Not sure what to make of all this, lol... cannot believe the differences in the displays on this phone. And why is mine so freakin' bright?? lol... Is it a freak accident or did I maybe somehow get like a 2nd revision screen on my phone? Not sure... What do you all make of this?
I've noticed no tint on mine and it's plenty bright. I keep it at 60% and it looks great

Mine is good and keep at 40 to extend battery just a bit. When rooted and I remove a lot of junk I will be ok for whole day.
I also noticed that (see my reply in "screen problem" thread).
http://forum.xda-developers.com/showpost.php?p=54262695&postcount=17
Open Google.com with Chrome (or stock browser) using desktop view to compare.
I used my Note 3 to compare (100% brightness).
The one has "reddish" tint seems to have more problem (dark screen, overly shaded fonts on standby screen) while "cool tint" one looks "normal". In addition, I found out cool tint one runs cool.
Nope no color tints

It's crazy how bad the differences are! There haven't been many reports of bad screens, but when there are, it's usually the T-Mobile version. No idea what's going on with their phones.

Some of the screens on the T-Mobile models vary wildly from phone to phone. If you have a good screen, then cool... but some of us do not and are trying to figure out what's going on.
ATT model I had was warm/yellow and also a little brighter. TMO one I bought yesterday is cool/blue but a little dimmer. I always prefer the cooler blue screens.

The reason not to buy warm tone screen one is such screen appears to have more problem (heating, overshadowing, and darker screen) than cool tone screen one.
Both were adjusted to same conditions (brightness, wallpaper) but the one on the left did not have data access.

I already set the brightness to max on both, and set no color adjustment on accessibility.
Even you may not be able to see the page, check out the soft buttons on the bottom.
In addition, I need to check the return policy if I get "warm" screen one because I mentioned above.
