Problem with Yellowish Screen, contrast theory

My theory is that HTC has sourced a different manufacturer for their LCD screens on the the TD,but the roms/driver (not sure which it is) they release have the same contrast values set for the old LCD's thus making the new LCDS, to look washed out.
The only way around this I can see is that HTC should fix these levels for the new LCD's in their rom's/drivers or someone with the skills to reverse engineer them and alter the values.
What made me think of this therory was that someone took a screen shot and altered the contrast in a paint app on the TD making it look vibrant and thus getting rid of the yellow tint and dull look, proving that the new display is capable of showing true blacks and not washed out greys..
Makes total sense to me..

Link ... Shown the old and new LCD's (new LCD with wash out, yellowish tint - is the one on the right)
http://www.youtube.com/watch?v=7cVGORLm-Qc

Yes it's indeed possible to have good contrast & vibrant colors on the yellowish washed out lcd's, I use resco photoviewer all the time to adjust the photos / images to look great on the screen. If we only could adjust the contrast on the screen itself so it would look good troughout the whole ui would be amazing...

i read somwhere the phones manufactured in china are the ones whith nice white vibrant screen and the phones manufactured in taiwan have the yellow tint or is it the other way around!. mine was manufactured in taiwan or so the sticker says. it has a white display. i feel sorry for anyone who has a device with the yellow tint it looks horrible.

argh. Mine was in glorious white, until I sent my Diamond in to have the touch screen replaced. It's yellow now!

I think a majority of the Diamonds have the yellow tint displays, it's a new one (probably cheaper) HTC have started using...
I also believe the Touch HD are having the same yellowish displays, but with the higher resolution of course.
Actually they're pretty good displays but if compared to the whiteish ones they'll look bad of course.

I bought a European Diamond back in September 2008 with superb lcd quality. Now I got it replaced under warranty, but the new one has awful contrast, especially when you look at it from an angle (45 degrease or more), it’s just horrible.
I actually managed to talk to the technician who worked at my phone. He said that all phones manufactured in the beginning had the bright screens, but HTC switch to this, probably cheaper yellowish screen soon after, and all replacement screens he gets from HTC in England are this low quality version. He even shown me a new phone whit this same yellowish screen, so I don’t think is country specific.
I am going to send HTC technical support an email, but I am not getting my hopes high yet. Overall I am greatly disappointed in HTC quality products, as this is not my first big issue whit this phone. Five days after I’ve purchased it, the mother board died and the replacement one worked … one day until it died also.
So if you have the bright lcd version, think twice before replacing it. If I known this would happen, I would have stuck with the original one, even though it had some issues.

I got mine a couple of weeks ago,came from hong kong,and had russian cd and booklet's!!
Had official 2.03.456 rom WWE installed.
My screen has very white white's and black black's,great contrast,easily the best quality pda phone screen I've owned colour/contrast wise,glad of this because this was the only reason I chose it over the HD which from the video comparison's between the two show the HD has grey black's and yellow white's,look's washed out.
Hope I don't have to get my diamond screen changed otherwise it's best feature will be gone looking at the picture's above......I feel lucky.
Just a pity the screen require's soo much stylus pressure to use.

It mite of been me that made that point in an old thread months n months ago, i work in the online returns department for o2, there was talk of us stocking the diamond, but the suits decided not 2 after vodafone stopped stocking the handset after it was said that atleast 40% of the screens produced in 2008 were made in china for just a portion of the price of the other screens that was made in taiwan they seem to be the ones with the yellow tint issue!

If you cause enough trouble they will replace it, customers like you need to let htc know that ur not gunna put up with such low quality components! not for the price htc expect you to pay amnyway! i wish you good look in your quest

Install Advanced Config and set Pressure Threshold and Finger Pressure under section HTC TouchFLO at 80866, and touchscreen is super sensitive.

Yes have messed around with advanced config,although I didn't change the value's as much as you suggested,still is the least sensitive winmo device screen I've used,it's fine with finger use,with the stylus it's annoying and a lot of non registering for me,and watching a lot of youtube video's on it before I bought it,noticed a lot of missed tap's from the reviewer's also.
Still,it's a pretty screen to look at though.

Note4 AMOLED Screen Quality *updated 11-11 reply from displaymate*

As some of the Note3 members may remember, I made a big thread in Note3 General Forum in regard to the display quality of the Note3,
you can find it here: http://forum.xda-developers.com/showthread.php?t=2463786
Also, I made similar ones on note2 and generally about AMOLED development over time.
So, as I got my new Note4 (Snapdragon) yesterday (from Amazon Germany), it's time to take a closer look on the AMOLED of this brand
new device.
My first impressions are:
The display is overall way better in terms of color shift when tilting the screen, but:
At least on my first device there is a noticable shift in brightness on the right side of the screen, especially on the lower half of the screen.
On dark grey backgrounds (as for example the XDA app with the dark theme has) you can see a contrast or brightness loss on the lower
right corner.
But my unit has an other, more dramatic flaw: On the left side of the screen, just where the lower end of the volume rocker is located, there
is a 0,5mm area of the screen, where it seems like there is something between the screen and the glass, but there is nothing! on light backgrounds
the spot gets darker, on dark backgrounds the spot gets brighter > very annoying!!
But I guess this is a non common flaw, which is really bad luck and has nothing to do with the uneveness mentioned above.
The funny thing is, this time I really thought I wouldn't have to switch devices, because the screen is otherwise really fine, but the spot-flaw
ruins it for me...
So I ordered a replacement today at amazon, as soon as I have this second device I can compare the two in regard to the AMOLED quality,
and then I will update this post!
What are your first experiences with the screen?
Regards,
Markus
Update 19.10.2014
Got my second device on Friday, and I've seen a third device from a friend:
My second device has a better screen in regard to uniformity (no darker right side of the screen), but: it is darker and has a slightly red tint when
viewed from the center. Also, the color shift is worse when tilting the device.
When I lay my three devices (note3, 2xnote4) side by side, enter *#0*# and compare the screens (walking around, looking from different angles),
then my hand-selected note3 has FAR the best performance in terms of neutral white, and tilting color shift is much less then on both note4.
the device from my friend has a worser red tint when looking straight on, but again tilting performance is better then my second device (although
not as good as on my note3)
conclusio so far:
.) note4 has worser tilting performance (color shift when tilting the device) as note3 (maybe due to higher PPI)
.) again, there are huge differences between different devices >> display lottery is back once again!
Update 02.11.2014:
After seeing a lot more of Note4 devices I'm now finally sure that on Note4 the displays vary a lot. "Perfect screens" are very rare, the best one
I've seen so far was on display in a "MediaMarkt" Store in VIenna. It was a display unit (without radio module), but the screen was a lot better then
on my current Note4. White was much more stable when tilting the device...
Today I had the idea of writing to "DisplayMate", because they tested a lot of Samsung AMOLED devices and their reviews always praise this screens
very much. Would be interesting what they would say to our issues:
Here is the mail I wrote them:

Betreff: Samsung Note4 Display Quality (XDA)
Wichtigkeit: Hoch
Dear ladies and gentlemen,
I’m writing to you because you compare and evaluate display devices and rate their screens.
I know your evaluations since years, and I like your scientific approach.
Let me give you a short description of myself:
I’m a consumer electronics freak with a plethora of devices, mostly from Samsung (I do not like
Apples overestimated marketing crap) and I’m especially a freak when it comes to displays. I
owned several AMOLED devices so far (Galaxy S1, S2, S3, Note1-4, Tab7-7, Tab-S(both)) and with
ALL of them I have to exchange them 2-8 (!) times to get one with a decent screen. Trust me, the
devices you get are cherry-picked from Samsung, or if you bought them randomly you must have
been VERY lucky!
I’ve a MSc in engineering and I hold product development lectures at university, so I know what
I’m talking about tech und manufacturing. Believe me, Samsung has big issues when it comes to
display quality. Their luck is that most people do not compare identical devices, therefore most
people would think their screen is ok and not bother.
So, what is the problem:
As you can see here on XDA developers:
http://forum.xda-developers.com/note-4/help/2-white-tones-screen-t2926527
http://forum.xda-developers.com/note-4/general/colour-tint-screen-t2909552
There are some threads in regard to this problem, as well as pictures.
I for myself created one huge thread for Note4:http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
And for Note3 as well: http://forum.xda-developers.com/showthread.php?t=2463786
If you search you would find a lot of other threads in regard to Samsung’s AMOLED screens.
In short: The displays of otherwise identical units differ A LOT in terms of display quality. If you
buy 10 Note4 devices you will get perhaps 1-2 with a perfect screen, all other devices would
suffer from bad viewing angles (HUGE discoloration when tilting), uneven brightness distribution
(yellow corners, especially right side of the screen and lower half), or very different white tone
when straight viewing on. I did this since note2 this way: Purchase a few devices, select the one
with the best screen and return the others.
I think this has mainly two manufacturing reasons:
1) The panels are cut out of a wafer. Screens from the center of the wafer are perfect, screens
from the side regions suffer from uneven color and/or brightness distribution depending from
where of the wafer they have been cut
2) Uneven or otherwise not proper coating of the screen. A too thick layer perhaps could cause color
problems.
Nevertheless, what bothers me a little bit is that you do not mention any of this in your reviews, and
people think they have a perfect screen. It would be nice if you response to this issues and at least tell
us what your opinion about the reason for such huge quality issues is.
I will post this mail also on XDA, if you want to you can reply directly there.
Thank you for your otherwise brilliant work!
Best regards,
Markus

Betreff: Re: Samsung Note4 Display Quality (XDA)
Thanks for your Email. Feel free to post this.
We get many Emails like yours with every display review article that we publish, with readers sending in comments and sometimes screen shots of their display, or even multiple displays side-by-side to accentuate the differences.
For our public article series we publish the results that we obtain. There is no question that there are always some defective units, substandard calibrations, variations between production lots and within production lots, variations in display performance, variations between displays from multiple suppliers and manufactured in different factories. We have no way to evaluate the scale, frequency, and validity of these issues based on reader Emails so we don't discuss them. All products, from displays to cars, have quality control and variation issues - consumers know this. We simply tell people that if the display is unsatisfactory then return it for exchange or refund.
For LCDs, a well known issue is the variation in the White LEDs used in the backlight - their color, brightness, and power efficiency all vary significantly. Manufacturers pay varying premiums to have the White LEDs pre-sorted into similar performance classes for their products.
We get many more Emails from unhappy iPhone and iPad customers than any other manufacturer. One possible source is that Apple uses many different suppliers for their displays. However, over a one year product cycle we may test a dozen iPhone and iPad units that are sent to us from multiple sources (including Apple competitors), and over many years we have never found any significant variations in display performance in our lab tests. I don't doubt that there are always some quality control and performance variations, but we have never seen any in the large number of Apple products that we have tested.
We don't get many Emails regarding Samsung OLED displays. Most seem to be the result of the sender leaving it in one of the default Vivid modes instead of the accurate (Cinema, Movie or Basic) mode that we use in our tests. Samsung is a single source manufacturer so that is not an issue. We also test many Samsung OLED devices (including many supplied by Samsung competitors) and have never seen any significant display performance variations within a given model. Again, I don't doubt that there are always some quality control and performance variations, but we have never seen any in the large number of Samsung OLED products that we have tested.
In any case, for our public article series we publish the display results that we obtain in our lab.
While it is difficult to get an objective statistical measure of the frequency and size of display performance variations, I highly encourage you to publicize this issue, perhaps via a youtube channel that can act as a central clearing house for this display issue.

@TML1504, Hey! I do remember your thread at the note 3's forum, was pretty awesome buddy made me change 4 n3's of mine to get a decent display due that that xD 1 thing I'd like to know is does the red still changes to orange even by tilting it a lil bit like on the N3, Ty.

Yes it is. For me it almost detracts from all the good points about the screen; no point harping on about perfect colour accuracy if you can only see that when viewing the screen from exactly 90 degrees.
Sent from my SM-N910U using XDA Free mobile app

Yeah..it happen to me also..seem like at the right bottom the screen turn into pink white a bit at white background color..but it much better than my note 3..

Id suppose the same screen issues are on the Note 4 as well, lottery time.. I really like the note 4 due to the design but the lottery makes me think twice but maybe ill get it at a later date I wonder though how good are the dark greys on the Note 4, on the note 3 its terrible.

The screen on my device is flawless, I've loaded up that picture of all the wool and everything stands out clearly and vividly. Red is red and Orange is Orange etc.. if I tilt the screen any direction nothing changes, it's perfect.

I've seen six Note 4 phones in various Best Buy stores. All of them had noticeable shifting of colors when tilting the phone left or right, and it did not take much tilting to notice. I've played the screen lottery too many times with Apple products, and the thought of doing it ever again with any product doesn't make me happy.
I'm currently out of contract and was 100% sure that the Note 4 was my next phone. Now I'm not so sure. I have a lot of tolerance for issues that can come up with this technology, but screen quality is not one of those issues.
Disappointing.
The thing is, when looking at any new device, one of the top complaints seems to be screen quality. If I rule out every device because of screen quality, I'll just be stuck on my S3 forever.
I guess I'm on the fence.

Maybe my eyesight is not so good :laugh:

I had the exact same problem with my first N3 that I got. I took it in to at&t and showed them and they replaced it. You couldn't see it on every "screen" but once you could it was evident that something wasn't right.

I too have this problem with colour shift on my Note 4, Can this issue be fixed with a software update?
I never had this problem on the Note 3

[Q] Does your screen have uniform color (or color temp?)

So we were discussing this on the other forum--google "uniform screen color" on android central for the thread. Someone posted that their screen color wasn't uniform, and so I shared my experience below.
I had to return my turbo because there was clear but subtle color difference depending on the area of the screen--almost like the color temp was getting warmer in the lower right corner, or like someone described, like there was too much brightness in one area vs another. It got more obvious to me as i used the phone, especially for reading ebooks.
When using the app "display test" from the play store, and the "viewing angle test" graphic, it was obvious that contrast, color, and white balance was different in the lower right corner.
I returned it, argued forever (2 hrs) with the manager at verizon who couldn't see it...until I showed him the test graphic, and he looked at the various parts of the screen with a jewelers loupe (magnifier.) They replaced it as a defect, but said it was so subtle they were basically doing me a favor. I disagree, but whatever, time will tell on these displays.
The new one, while MUCH better....still does not provide uniform color temp and brightness. It's disappointing, given how great this display was supposed to be.
I'd love if anyone else could look at the test graphics and see for yourselves...but be forewarned, as I said in the other forum, once you see it you can never unsee it......
And yes I took the plastic off of the screen.

Sadly I see the same on mine. Originally had a ballistic nylon model which had the issue and have since switched to the standard with the same. Mine is almost more of a banding horizontally across the screen almost like it heats up and cools down a few times through the height of the screen.

It's very, very slight on mine. Can't decide if its a swap issue for me yet.
Shame we don't have a way to back these up for issues, I just got it where I wanted it!

Huh? Its AMOLED RGBG, possibly the WORST display technology ever invented. How can you have expected it to be "great"?

I'm in the same boat. It's more noticeable on a white background. Any chance it can improve over time? I recall iphones having similar issues a couple years ago and people saying there was a "break in" period.

No idea. Decided to live with mine last high and today considering a return this afternoon, lol.

I definitely have an incredibly noticeable pinkish tint at the top of my screen. This is quite infuriating.
Sent from my XT1254

Are you going to exchange it? I thought about doing this, but I'm afraid the replacement might be just as bad or worse. I have the pinkish tint on the bottom half of the screen.

I'm curious as to how open Verizon will be to exchanging it for such a "minor" issue. I just got a replacement because calls wouldn't work on my first one, so I was able to get some pretty good comparison photos (both phones at max brightness viewing the same images in QuickPic with no ambient light photographed with my 5D): New phone is on the left.

I thought it did until I read this. There is a redish blob about an inch up from the bottom. Now I cant unsee it. I will wait a few months and the use motos guarantee let them work out the manufacturing issues first.

I think I am going to do the same.
My 3rd Turbo, after 2 14-day exchanges, only has a small line of pink about an inch up from the bottom. However, it also goes away depending on viewing angle (it shifts up once I view it past like 45 degrees tilting the top away from me). So who knows.

I know this is an old thread but I got my Moto Maxx today and it has this same issue towards the top part of the phone. I got it from swappa from a store in PR so I'm wondering if I should see if they will swap it out for me but it seems like all of them have it to some degree or another? I have also seen similar posts about the nexus 6 (not low brightness pink hue issue but like this, uneven temp) I'm wondering if I should go through the trouble if the next one will be the same

Just got my turbo last week and noticed pink discoloration about an inch down from the top and half an inch up from the bottom, full width of the screen. To those who have had this device for several months, does the pink go away? Anybody out there manage to get a non pink one? Contemplating taking it back after flashing back to stock image. Thanks!
Edit: Here is a pic of the screen at full brightness taken with my LG G2. Oops, there is some pocket fuzz on glass, don't mind that. The right side of the pic is the top of my Turbo screen and has about twice as much pink as the bottom of the screen.

Here is my Turbo next to a good one at Costco. Mine is on the right. Pretty easy to see how pink it is:
Funny story really...so I got a new Turbo after making sure the screen was good - no discernible pinkness from normal viewing angles. I took it back to work and set it on the wireless charger I got at Verizon a few days ago. When I set it on there, the phone apparently crashed and booted into Fastboot. I was surprised but thought maybe the case I put on it was pushing the volume and power buttons down, but nope it wasn't. OK, so I chose to Start from Fastboot, it rebooted right back into Fastboot...uh oh. I chose Factory and hit the button aaaaaaaand this Droid was never living again. It went black and doesn't do jack now. It charges still, so that part of it still functions, but nothing you push will cause it to display anything or vibrate, etc. Great.....back to Costco I go. This time the dude was all "You know...you fulfilled your early-upgrade requirements by sending in the Razr, you could probably swap your dead Turbo for any phone if you do Edge". Hmm, this was unexpected...welcome, but unexpected. I had the S6 staring me in the face and I know they got root on the Verizon version, so I got one of those, joining the sheep. I do miss the Turbo, but the S6 is nice, too. I don't know which one I like better yet, but I'm leaning towards the S6 without letting the 2 bad Turbo's sway my opinion. I did lose about $100 in screen protectors, cases, and Mofo with the Turbo experiment, but it was worth it to get upgraded 7 months before my upgrade date.
And ya the Verizon dude noticed the hash in the notification for the "SU binary update" or whatever, and SuperUser in the app drawer...and he just laughed. Glad I didn't waste my time restoring it back to the stock image.

Just got my turbo last week and noticed pink discoloration about an inch down from the top and half an inch up from the bottom, full width of the screen. To those who have had this device for several months, does the pink go away? Anybody out there manage to get a non pink one? Contemplating taking it back after flashing back to stock image. Thanks!
Edit: Here is a pic of the screen at full brightness taken with my LG G2. Oops, there is some pocket fuzz on glass, don't mind that. The right side of the pic is the top of my Turbo screen and has about twice as much pink as the bottom of the screen.

mine has a similar issue. the lower half of the screen has a pinkish hue. did yours get fixed?

Screen Defect in direct sunlight?

I picked up a T Mobile Note 5 today and noticed strange mark all the way up and down the right side of the display. It is only visible under direct sunlight or very strong lighting and most noticeable with white or light backgrounds. It looks like some sort of air gap or liquid between the glass and the display. I actually exchanged the phone and the new one had the same issue. Has anyone else noticed this?

I'm having the same issue. I posted my issue on Android Central and someone stated that this is a common issue with the S6 and Note 5.
I'm going to call Samsung support right now because T-Mobile stated "that's how it was designed" and that answer just doesn't work for me. Even if they are right.

Well I checked my phone in direct sunlight and I don't see the mark you're talking about. But I do notice that my screen / glass isn't clear... With the screen off and in the sun, looking at my screen at certain angles I can see horizontal marks on my whole screen. Does anyone else notice these marks?

I know exactly what you're talking about. Mine has the same thing. I was wondering if it might be the glass screen protector, but I wasn't about to remove it to find out. It doesn't really bother me, so I won't attempt to get it replaced unless it gets more pronounced.

I do not think I see the issue on my Verizon Note 5, however one thing I will say is this screen is amazingly bright, I can even use the camera outside in direct light and be able to see it perfectly.

I think you'd probably know if you did. It's really obvious on mine, but only in direct sunlight. In all other lighting conditions, it's completely undetectable. I'm going to try to get a picture.

I have it as well, and find it extremely annoying. This is also the 3rd unit I have had due to the bullsh#t pink hue on the other two. This one is being returned to the service center when I feel like making the drive, and I'm not leaving without a perfect display.

I have this issue as well not really that major It's only there in sunlight

Anyone found that this problem has been solved with a RMA or is thus just part of the way the phone's are?

I have the same issue with my Note 5 I bought it recently and works perfectly.
The display quality is amazing in any light condition, also the content is very clealry seen in the sunlight, but on the right side of the screen under direct sunlight, especially when then brightness is at 100% an I use a white backgroud some spots are visible from the top of the screen to the bottom.
Are these some sort of Burn-ins?
As tech service noted itnis a common problem with S6 and Note 5, also it does mot affect content visibility, however when Samsung manufactures such premium phone they should avoid such manufacturing errors.

Amoled display technology hasn't fully matured yet

Go in a dark room, pick a black background and notice all those marks. Amoled has been like this since day 1.

I see, this is chronic problem of Note 5.
Solution is: Do brightness as %99, 95, 70, 50 etc. in direct sunlight. Don't do it %100.
Check my problem too (similiar problem) : http://forum.xda-developers.com/note5/help/display-problem-note-5-t3206480

Had this issue on my first note 5. sent it out for repair and waited for 5 days and found out that the replacement note5 has pinkish hue at the bottom of the screen. can wait another 5 days with out the note 5. going to drive to the nearest samsung service center with is 45 mins tomorrow. let me see if i can get it right this time.

Slightly on topic my N5 has issues under low lighting as per pics. Going to send it back as it's rather annoying in the spot it's in. On low brightness the smear like line is visible when you take it off low brightness the screen is fine. Weird.

Anyone notice the small gap between glass and bezel on note 5? annoying dust collecting, my is the black version from T-Mobile

Whitestone Dome Glass blocking blue light

I was planing to buy the Dome glass for Note 20 ultra. Then I notice the Dome glass for Note 20 Ultra having the blocking blue light feature. I used one of those blocking blue light glass protector before. It makes my screen looks yellowish. The color of picture and video are all looks in weird color. I am wondering about how's color look like after using the Dome glass for Note 20 ultra. Will it turn to yellow as well?
It seems only the glass for Note 20 and ultra are having blocking blue light feature. The glass for S20 does not have this feature.

Ridiculous.
If I wanted my screen to look that way I'd have a wolf piss all over it!

i just Installed AMfilm glass protector on my note 20 Ultra, no tint. loving it

Find my answer in Q&A session on Amazon. Someone said it changes the screen to a slight orange color.

It does not effect the colors on the screen at all. The WSD quality is not what it use to be though.

I use the same protector and love it! I actually have a couple codes I don't need because I bought several and they contacted me. Most of my family and friends have upgraded to the Note 20 ultra. So I recommend this glass and I get stuck installing them on everyone's phone. Lol

Goes back nearly 20 years ago when sampling Luxeon Star white LEDs. Some had a green-yellow tinge that we nicknamed "wolf piss green".
A lot of the IPS displays of Surface devices had that sickly green-yellow cast too. Fortunately, it could be nearly eliminated to tolerable levels by calibration. Of course backlight bleed was horrendous. Surface Pro 7 and Surface Laptop 3 screens seem to have fixed both (finally).
Personally, cannot wait for OLED to take over all displays.

I sent you a private message.

I didn't notice the change, looks fine to me, turning on blue light filter is MUCH oranger. Still, I wonder if this new "feature" is why the fingerprint sensor is having issues on the N2U glass.

Agreed.
The 20 U has a near perfect color/gamma correct rendering. One filter skews all that down the toilet. The blue wavelength is one of the visible spectrums the OLEDs are designed to emit. Simply dail it down on the software side if it upsets you.
The eye damage done by blue light is across a band of wavelengths in the blue range not one single wavelength.
Even if you could filtering out a specific* blue wavelength it wouldn't work unless you deliberately wanted to be blue color blind.
The damage is cause because it a more energetic wavelength and the eye isn't as sensitive to blue as green; takes far more blue light than green to be perceived.
The same is true with the red wavelengths but these aren't as energetic and cause far less damage.
UV is even worse than blue but is beyond the human visual range so it can safely be filtered out with no impact on color perception. Ordinary glass filters out shorter UV wavelengths, the most dangerous.
*even a notch filter deattenuates adjacent wavelengths

I placed the glass half over the screen and tested before installing and noticed no difference at all. It would have gone back had it looked like what the blue light filter setting does.

Can you provide a link to this

I saw NO visible change by holding it up with the screen on a white background. or by installing.
I am thinking it's more of a marketing ploy.

I can also say this isn't true. But...don't buy a glass screen protector for this phone if you want a fps that works well..
