Hue Changes When Screen is Tapped

Hi all, I was wondering if anyone else is having the same issues as I am with my new 6800. I have noticed that on occasion the screen will change to a very light greenish hue when I press on the screen with the stylus. The screen immediately changes back to normal once I pull off the screen. This seems to happens several times throughout the day. Is this normal? Any possible fix? or return it? Thanks for your help!
Great forum BTW...

Yes, sometimes I do notice the hue change, but it doesn't happen very often. I don't believe it's a defect since I've seen it in more than one Mougls (though one had it worse than the other; the hue alternates with every tap or key press). Some expert opinion on this would be nice.

Not normal~! The first batch of Moguls did not have this issue and they came with a harder screen to the touch. the HTC replaced the screen to a inferior quality resulting to this issue. I am a witness to this. We have to live with it or nag enough about it. I personally made Sprint and HTC replace my Mogul4 time for this and every replacement had this issue. So to prevent myself from being dropped from, the service I will just suck it up. Sad indeed. But i least I gave them hell for it.

If what you're saying is true, then perhaps the three bright spots on my screen (from pressure against the carrying case) is also a result of this inferior screen. Curse HTC for their cheap antics!

I guess I'm going to go ahead and just live with it. I really don't want to go through the hassle of returning it just to get another that has the same issue or possibly something worse. Thanks all for your input.

WRONG.
not a hardware issue, really.
You'll notice the scroll wheel also sometimes causes it.
Its a driver issue... when any input is received (screen tap, hardware button, etc...), the screen hue shifts every so slightly. Most don't notice it.
Some people on ppcgeeks have reported that depending on the rom you use, sometimes it goes away.

Sorry, But I already went thru issue with HTC and SPrint. Neither both know why but they call it a defective unit. Reason why I state that the screen is different because I am furtunate to have bought 2 Mogul on the first day it was released. One for me and one for my GF. Then my Mogul ended up breaking its Stylus clip form the housing of the phone so like a moron I went over to have it replaced my Sprint thru the manufacture warranty. Spring decided to give me a onetime replacement thru the warranty. So when the phone got here first thing I noticed was a yellow color hue to the backlight and the screen kept changing from somewhat bluish tint to yellowish tint using any buttons including the scroll wheel and taping the screen. Immidietly I called Sprint and explained y frustration with this new usnit. They concluded that it was a defect. So the next mogul shipped had the same issue exept this one had a back backlight that kept shutting off. Again I sent it back and the forth mogul that I received had AGAIn a yellow look to it and dimmer backlight. I called Sprint and they said again that it was defective and to send it back. Now i finally got my 5th Mogul and this time the backlight was not yellow but more of a cold bluish color but more acceptable. It was not as brite as my first mogul but I just gave up on getting mogul after mogul and just decided to keep this one because I am sure If I send it back then Sprint will send me another yellow colored hue backlight again. How do I know that all my backlight on all those Moguls were kinda funny? Because I had my GF mogul in which was one of the first moguls sold. And comparing all the moguls to hers you can definately tell they are different. Also I must note that her screen is harder than all the new Moguls that i got. ALl my replacements including my current Mogul have a softer screen. Very noticable. That why I know for a fact that they changed screens to a inferior quality to cut cost. I must recommend everyone with this same issue to have them call Sprint and have them replace your unit. This way they can force HTS from replacing screens int he near future. Here is a pic of a mogul with a yellow hue backlight that flikers different colors when tapped or using the scroll wheel. You can see how the Mogul on the right is soo much whiter like it should be, this is my GF mogul. Her manufacture date is May 3 2007. One of the first batch of good moguls. Now you can see that my story is real and I am not lying or making up anything about the screen being different. So its not a driver issue. Its a DIFFERENT SCREEN all together. Remember when you break you mogul and have it replace.. compare both screen before you decide to stay with your replacement.
PS. My GF screen is very White and Bright and never flickers different colors when tapped. Its rock solid. And also if I tap it normaly I can really feel a different in how much harder her screen feel. Im 100% this is a very superior screen ALL moguls should come with. But we are not HTC and cant forced them to switch back

Wow from reading people's comments I didn't think it was that bad. After seeing your picture though, that is completely unacceptable. Send a letter to HTC along with the photo and demand they send a replacement!

You know... im sick of having to wait a week for replacement AFTER REPLACEMENT from sprint and the same bad screen i get. But i will emal HTC and see what they say.

evo screen issue, anyone else?

i noticed today that my evo's screen has some sort of light warping near the bottom left corner. i don't have a picture to show, but i'd like to know if anyone else notice something like this. it's most noticeable when the whole screen is white (like a webpage) and then hold the screen in front of you with the top tilted slightly toward you like 20 degrees. i get a little diagonal light warping near the bottom left corner, pretty noticable.
i'm not flipping out too hard because it's not noticable except from this angle. looking at it directly straight on looks perfectly normal. but i want my evo to be perfect!

That is normal the EVO is equipped with a backlight so when you tilt it it will show
its not a hardware issue its normal dont worry..also were did u get ur evo???????
also im the first teen to play with EVO...LOL

i took some pictures, see the diagonal line near the bottom left. that really doesn't strike me as normal!

That's just imperfections with the backlighting for the screen, it happens.

I can see the lights at a angle but I have to turn it completly flat to see the lights. Yours looks like its lighting your screen. My evo does not do that.

damn

I would definitely take that back to the store I got it from if mine did that. Since it's a gift, you might be SOL, unless you go through HTC? Not familiar with warranty stuff like that...

I'd be pissed if that happened to me again. It happened with my Touch Pro and as much as I tried, I couldn't get a replacement or repair. No one would even acknowledge that anything was wrong.
On a very related note, I think it sucks that there is backlight leakage at the bottom of the phone casing. I hope this varies from unit to unit.

My Evo does have this as well.

All EVOs have that light bleed on the bottom. Almost every review has commented on it. They've also said it really isn't a deal killer.
Guess some folks are pickier than others.

It just happens, design flaws. I'm tempted to wait and get a later revision EVO.

I did read about the light bleed before buying. I do not mind the light bleed. Its not that bad on my Evo. I am very happy with overall build. Cant find anything wrong with the manufacturing process on my phone.

Take it back. That is definitely not normal.

mine have that as well

the LED leak from the buttons is normal, the bent TFT LCD screen is not. The display should not look like that.

They probably gave out blems at the Google I/O. just kidding.

Funny enuf mine doesn't have the button light bleed at the bottom. I guess I should be happy about that

My EVO does not have any light leakage whatsoever.

I guess you could chalk it up to the Google I/O batch being the first batch of Evos ever produced. After all, aren't they Developer models? I'd imagine the final version meant for consumers would be free of problems such as the light leakage.

Just swapped out my EVO and got the replacement. Two new things on the EVO.

I just wanted to say that I got my EVO replacement due to the screen separation issue. Anyway, as soon as I got the replacement phone I noticed two things that were different from my first EVO.
1. The back cover: The back cover on this EVO is a little darker than my original and seems to be made of that scratch resistant rubber plastic on phones like the Palm Pixi. It's not as rubbery as the Pixi but it's there and it's definitely different from my first phone.
2. Screen Brightness: The screen on the replacement is much brighter than my first EVO. Even at the highest setting on my original I was a bit disappointed coming from the Nexus One. This second phone is easily as bright as the N1.
Could the phone really be a little different this early on in production?

Whats the hardware version?

It says 0003. I never checked my first EVO though.

I received an 0003 on launch day. It does not have any of the issues so far that people have been plagued with.. I have noticed that the light from the buttons bleeds through to the lcd screen which is annoying and is more obvious depending on what is being displayed on the screen. There is not screen seperation or light gap between the frame though.

I have one of the first batch EVOs and mine says version 0003 as well. Maybe they didn't bother changing that information?
I wish there was a way to compare. Either way, I'll probably wait and see if my EVO gets any worse within my 30 days before I ask them to swap it out for a newer version. But I also don't have too many issues with it. My touch screen works properly (not sure if there's an issue or not because I tried it on my pillow again this afternoon and it worked fine) and my screen has not separated yet (though the light does still leak through a teeny bit).

I have version 2 and I haven't had any of the issues people are mentioning. Hopefully I don't have to swap mine out.

I've got a v2 and no issues except for the ground one which I don't really give a crap about.

I have version 002 and I don't have any problems I hope. I do get the problem with my screen not mounted correctly so when it is on a table the screen is not working properly

All 3 of ours were 0002 from sprint.com on launch day; all 3 have the glass problem and mine has the blown speaker problem.
Hoping when they get them back in stock, the exchanges will be better.

Yeah, I also have a 002, most likely because I have a Google IO phone. It seems to have none of the problems that are being talked about—not even light leakage or touchscreen. Only problem out there is the 30FPS cap and that's established to be kernel/firmware. Seems like the first true production run of EVOs had some shoddy work...

Odd because my Evo is from launch day and has the rising screen issue but it also has the same back cover and very bright screen you seem to be describing on your replacement. I kept comparing my Evo to my HD2 and saying wow the Evo screen is so much nicer and brighter for some reason.

Have you tried pressing down on the glass just below the 4 touch buttons? I had the light leakage since day one but I had read about it in a few tech blogs who demoed the Evo before launch and said they noticed that so I figured it was just a flaw to live with on most if not all Evo's. But now that my screen raised up and can move up and down a bit, when I press down hard enough (which isn't very hard), the light leakage goes away until I remove my fingers or until the screen decides to pop back out later.

Guess I am not the only one noticing this:

Second EVO (replacement for first.
Im currently on the second EVO now and I too niticed a difference in the brightness from the first one. This one it brighter and the bottom 4 buttons are evenly lit on this EVO. The Hardware on this current EVO is 0003. I dont know what the first EVO was. I am currently waiting for sprint to get more in stock so they can send me a 3rd replacement. This model has the yellowish vertical lines in the screen,
Today I went to use the front facing camera and the phone froze, rebooted, and now uses the back cam no matter what setting I put it on. It seems like the front cam is nonexistent. I have done a factory reset and still nothing. I dont understand what happend to HTC's quality controll from Hero to EVO. The Hero I had had ZERO issues and now these phones are falling apart right out of the box. Way to go HTC!!!

I have 002, having the glass issue along with light bleed. Right now it's not that bad when I have a case on it. But I am going to get TEP and get a new phone a year lol.

Dark patch on screen

Has anybody else noticed a dark patch on the edge of their screen? Along the top side of my screen, I can see it going off white when browsing a website in portrait mode for example.
It's like the back light isn't working properly there or something. Anybody else got this, should I get a replacement?
It's not hugely visible but it's noticeable on a white screen at any brightness level

Idk, it's up to you. I have light bleed in my right hand corner that is always visible, unless your in a well lit room on 0% brightness. I can't decide whether or not I want to send mine back though because of how common these backlighting issues seem to be.

Yeah. Mine is flawless otherwise. Its so barely noticeable I think I'll just get used to it.

Same ha ha, other people can't even spot it when i point it out to them on auto-brightness.

Yes, I noticed mine right away, but like others have said, its hardly noticeable. It doesn't bother me at all...
Sent from my Nexus 10 baby!

Same thing here. Most noticeable on a solid white background. I'm starting to think it's not a lighting problem but something to do with the way the panel is manufactured. If I hold the tablet in landscape so it's perpendicular to my face with my eyes lined up with the camera, the brightness is even across the panel. As soon as I tilt the bottom towards me, the brightness falls along the top edge. Makes it seem more like a viewing angle issue related to the way the layers are assembled or maybe a difference in pressure on the panel along that edge.
I decided to live with it because it's very rare that I have an app running in full screen that puts a light background across that area.

Same issue for me as well

I had the same issue with my first unit, did RMA and got second one. Second one had the exact same issue. Finally decided to get refund. The play store customer support said that there were few people reporting it already. This might be a design issue as well- the way device is tapered differently at the edges(backlight might not be aligned properly), two strong magnets near camera etc. Just speculating.

Dark patch here too. RMA process underway. 1/3 of screen has yellow tint. Noticeable when reading on white background. Annoyance.

Keep us posted on the replacement device!

Same problem here. I received my Nexus 10 yesterday and notice dimming primarily (exclusively?) along the long edges. While reading a web page with a white background in portrait mode I found myself wondering if chrome was adding a gradient to the edges for some stylistic effect, but realized that made no sense. I observed the same problem with Firefox, and then I installed a screen testing app and observed the dimming with a solid white screen.
It sounds like this is probably a manufacturing/design error. Now I have to decide whether it's worth the rigmarole of exchanging the device, probably to no effect. I guess this is the risk you take when purchasing a device sight-unseen.

If you bought it from a store it would still be unseen, since it would be in the box. I had the same problem with the iPad 3. It took me three exchanges to get one with an acceptable screen. All of them had dark, blotchy, yellow patches. By all accounts it's due to the adhesive glue they use. We shall see what the replacement brings. Order is currently at the 'pending' stage.

I also have this on my screen. Right side when in portrait mode. You can't see it in landscape, which is weird. My wife and I have decided to keep it, though, as everything else about it is perfect. Plus, this defect, if you want to call it that, does not detract from our enjoyment and uses.

To clarify, I meant that I'd never had the opportunity to use *any* Nexus 10 in person. Had I done so, and noticed the dim edge, it would have at least raised the possibility that there was a design or manufacturing issue.
Speaking of which, I examined an in-store Nook HD+ display unit yesterday and what do you know: it had the same dim edge issue.
By the way, where did you hear about the adhesive glue explanation?

Mine has--I assume--the same dimness along the entire length starting about 1/4" from the bezel along the "top" camera edge. It is actually somewhat distracting when reading a book in portrait mode. If I flip the screen around so that the dimness is on the left edge, for some reason I find it much less annoying. Unsure if this is a warranty replacement issue though. I haven't found another Nexus10 to see in person yet.

It was all over the iPad forums when the iPad3 came out. Plenty of people with dodgy screens. Some reported success in leaving brightness turned up to max and plugged in for 24hrs etc to dry. But may have been placebo. It could also be an entirely different cause other than adhesive. After all, what do I know? In any case, mine's heading back, but the replacement is still stuck on 'pending'

I had a rare bit of luck. Somebody sat next to me on the bus yesterday evening and pulled out an oddly familiar black tablet. I explained the problem I was having and asked if I could examine his Nexus 10. His device had a perfect display, with no detectable dimming near the edges. So the issue appears to be a manufacturing defect, not a design flaw, and something that could in principle be solved with a replacement unit.
I called Google last night and have my RMA email. I'll ship it off this weekend.

[Q] Visible "cells" on screen even when the screen is ON

This is not about the tiny silver dots you can see in certain angles when there is glare on the screen. I sold my 8gb Nexus 4 and bought a 16Gb but the new phone that just arrived has a bunch of vertical lines with 3 small horizontal lines which I assume is the digitizer and it is a self capacitance circuit. The problem is that it is visible ALL the time, from every angle even in dark rooms and while the screen is on. My old 8Gb did not have this problem (just the silver dots), is this enough for an RMA? I'm trying to get used to it but it is really distracting. Here are some pictures:

I would RMA that, that shouldn't look like that.

Yeah, I'm going to call google and see what they say. Sucks though, the screen had great colors, FAST binned, and running stock got me a score of 19k in Antutu.

I can see that on mine too, it's the LCD matrix. Was similar on my One X as well before I sold it. Doesn't bother me one bit

It's the digitizer. Nothing to worry about.
However, i don't see them when the screen is on.

I can see it if its a dark sceen, like if I pull down the notifications bar. What kills me is that my old rev10 Nexus 4 doesn't have that.

I emailed Google the picures of the screen and they said that it was defective and setup an RMA. Just wanted to post the result in case anybody has something similar. Thanks everybody.

I have that too, but it doesn't bother me since I only see it on some angles with the screen off. Apparently, from what I understood, it is actually a sign that you have a newer type display without the 'washed out colors' issue.
Please post pics of your replacement N4 when you get it to see if it is any different (I'm somewhat sceptical), since I think many people have this issue.

The replacement hasn't shipped yet, will let you know when I get it but this is most certainly a defective screen, the two phones side by side in the first post are both rev11 301k and both arrived about a week apart in february. One has the digitizer marks that are barely visible, only from certain angles(doesnt even show up in the pictures) and when the screen is off, the other one I can see them from 4 feet away. I have to agree on the colors though, the 301k has much better colors compared to my old 211k.
