Screen discoloration? - Sprint HTC EVO 4G LTE

Does anyone else have screen discoloration near the bottom by the capacitive keys? Its only visible on lighter pages, ie white or off white colors such as web pages and the xda app...not sure what to do about it and if its normal
Edit: seems to be the glue related yellow tint?

Yes, at the very bottom. It is slight but there on white pages. Not as concerned about that as I am about the LCD flex issue.
This screen is beautiful but the manufacturing process and lamination of this screen currently has issues!

I know, it's such an amazing screen. Not sure what to do about the discoloration. Do you think it will go away with time if it's the glue?

I have the same issue. The whole screen has a warm tone but on a white screen you can certainly see a shift towards yellow on the very bottom portion of the screen. I personally think it's from the buttons.

[Q] Light bleeding into screen from capacative buttons?

Just wondering if anyone else has noticed this on their RAZR. While in landscape mode (I first noticed this while watching Netflix). In the corner near the search capacitive button I noticed the lighting for the capacitive button seeps out a little, like a very small amount. It doesn't overwhelm the screen or anything. When holding my phone upright and looking down towards the capacitive buttons, I do notice some light coming out from the left and right corners. Just wondering if this is because of the design and is normal? Or is it a flaw in the phone? Thanks!
I have noticed this as well on my unit. I have also noticed black blotches on the screen that can be seen when the screen is completely black.

Hmm. It is somewhat hard to notice, I'm still wondering if it is a design thing or flaw.
I have exchanged my Razr and there is still light bleeding from the capacitive button (search). Also the black blotches remain when the screen is black and the backlight is on.

Thanks for confirming this.
droid razr
My screen also has the blotches when the screen is black and in low light conditions.my capacitive buttons also bleed into the screen in the corner but its not something i notice only when i really scrutinise the device.
I have a small streak or two of the blotches but they're only noticeable during the black boot up screen, not when using Netflix or YouTube.
There's absolutely no leaking from the white light of buttons though..
I also have the black bloches, it's like the screen isn't AMOLED; the black's aren't completely black, i compared it to the Galaxy S 2 and on the Galaxy you can hardly see where the edge of the screen is because it is completely black but on the RAZR it's as if the screen is more greenish where the Galaxy would be completely black.
The black's look better on the first Galaxy S than they do on the RAZR
I first noticed when i started using NOLED, i like it better than the led notification light on the RAZR
In any case, quite dissapointing
BTW i don't have light bleeding from the capacative buttons
Hmm. So some units have it and some don't? I do confirm the black blotches when watching netflix and the screen goes black you notice it. The light bleeding i noticed while watching a full HD movie and I was like eh.. What's this tiny flash moving in the corner. That's when I noticed the light bleed, and it occurs only when the capacative buttons are on. Another member stated that he exchanged his RAZR and his replacement one has the same issue as well. I've looked around and it seems other devices also have this issue as well. Not sure if it's just a design flaw or defect.
@Dusanzk you might actually have a defective unit if that's the case, cause some people were complaining about a green tint on the phone. My blacks and black, why whites are white, I have no problem with colors at all. Just that bleeding ;(.
It's quite hard to notice at first, i only notice in the dark and when the screen is completely black.
I downloaded an app called Burn In Tester, you can adjust the colours on your screen to see what they look like and when i choose black that's when i notice it.
Regarding the green tint, i'm not sure that's the problem i'm having because it's only a problem when something black is showing on screen and it's dark, in all other situations the screen looks amazing, like my Galaxy S 2

[Q] screen color issue

Hi. I noticed that the colors of the screen of my i9300 is not uniform. For istance, when I load a full white page, the top of the screen is lightly blueish/greenish than the bottom. Do you have the same issue? Is it normal? It is not the angle of view. Thanks
I do seem to have a very mild case of this, but only noticable on a white screen. The top of mine is very slightly yellower than the bottom.

Light bleed through

So I just picked up the DNA today. Loving it! However, I just noticed that I'm seeing light bleed through on the bottom, just below the capacitive buttons when they're lit up. Anyone have this?? Really disliking this!
Yeah. Pretty common.
It is really easy to fix though and you can do it yourself. Unless you want to keep exchanging them and hoping you find one, this would be a better way.
Go to your local auto parts store and pick up this:
http://www.apmengineparts.com/82180.html?productid=82180&channelid=FROOG
Get the smallest one you can because you are only using a bit.
Take a toothpick and apply it to the bottom of the glass where it meets the plastic. Try to push it into the crack, if possible. Let it sit for a few seconds and then take a paper towel and wipe it off along the crack. DON'T get it into the usb port!
Let it dry for a few hours and you are good as gold. It also has the bonus of increasing water resistance and keeping dust out.
Mine didn't have that at all. I guess I got lucky. I do have a small spot almost dead center on the screen that looks like a bluish smudge though. You can only notice it on a white background. It's musky annoying but faint enough to live with.

Mine does, I hate too, at least I'm not the only one with it. Still debating if I should exchange it or not....

I have two spots on the botton too...never had this issue with LED screens. How likely is it not to have the light bleeds? If this is indeed a common problem for the DNA, I won't bother exchanging mine

Hmm I guess it isn't something to be concerned about then.
I checked mine again right now in the office restroom with lights off and the phone screening an entirely black image; it does not have any light leakages at its full brightness, but there are two centered light spots triggered by the capacitive buttons that are only visible at the lowest brightness level.
Therefore presumably, turning off the capacitive button lights will eliminate the seemingly light leakages, as they do not seem to be defects caused by the LCD panel itself. But if such a leakage is glowed anywhere else but about the two centered areas just above the capacitive buttons, such as any corners or left/right/upper edges, then it would indeed be a sign of a defective unit.

Well in case nobody noticed when the lights are on and you are in a dark room and you tilt the top of the device away from you, when you get to a certain angle you can actually see the light from the buttons because of how the glass is curved. This will appear on every DNA because of the glass. so if you have light coming from BELOW the buttons make sure its not this that you are seeing.
I only have light bleeding through at a certain angle. I may pick up some of that stuff though.

In my case, its coming from the seam between the curved glass and the trim.
Mine too, I can see it from any angle. There's two spots where it bleeds, the gaps between the captive buttons

Well, at least I'm not the only one. Might just try to ignore it...we'll see how that goes...
Yeah I'm still torn about what to do. Kinda want to relock/ruu and exhange but what if the new one has something different wrong with it. This one works great, the bleeding is just visual and only in a very dark room so might just do what adryn did and seal it with some gasket maker

I just sealed mine. Took 5 minutes tops, and only because I was being precise.
No more light bleed and increased resistance to dust and water.

You think that's really what they're seeing? You can't physically stop that without changing the shape of the glass. i prefer the continuous curve over a slight refraction you can't ever see.

I'm certain (in my case) that its the glass and the trim.
Nothing a little black silicone doesn't fix. The shape of the glass is not the problem. The problem lies near the capcitive keys where the glass meets the glossy trim. They are two different pieces.

Droid DNA Interior Photos

So I cracked the glass on my DNA So I decided to take the opportunity to show everyone the inside of the DNA
I still have all the parts, so if anyone wants specific shots let me know.
P.S. Do we think the yellow gasket and white goo = waterproofing?
Cool!!!

No LEDs.. It appears to be a strip of Electroluminescent Paper or a bit LCD back-lighting without the LCD-ness. My bet is on the latter.
(Sorry, by this point everything is glued to hell... so I had to move to destructive disassembly)
Hope this helped!
Cheers,
so cool, thanks!
i was triyng to look for that "soft spot" on the back right which if pushed, caused the LED discoloration..there appears to be A LOT between the actual screen and the back plate, and it's symmetrical...yet the left side didn't have hte same soft spot the right did.
that's what caused my blue dot issue..but judging from these pics, there's alot between the back and the screen..so man, even lightly pushing that spot showed the discoloration..
I thought I was the only one with the blue dot issue, I sent mine back to Wal-Mart & they sent me a new one thank goodness. My bluish blush spot was about 1/2" above the home button & a little off to the left.

That is exactly where the magnet for the rear speaker is.
I tore a part my evo lte when replacing the screen. The DNA looks like it was designed by brilliant engineers. The evo, in comparison, looks like it was designed by a carpenter.

There are LEDs, they just are not on the LCD assembly, they are on the front side of the speaker board on bottom. I took my DNA apart and posted pictures of it all a while ago on droidforums, i posted link bellow, you can see the LEDs (there is two of them) on the front side picture of the speaker board which goes on bottom.

Look at this photo.. the LCD covers up pretty much the whole area and would block anything coming from the speaker assembly. How would it shine through?

yes the first picture you linked is correct. Those two leds on bottom are the LEDs for the touch buttons. Trust me the light goes through lol, that bluish white film or whatever color it is, is tinted and light passes through it. Try holding a flash light behind it. They tint it so the light doesnt just shine right through and look ugly, this way it has a even spread and isnt blinding. Even though id rather have mine a little brighter.
I was able to adjust their brightness with this app..

Don't think they're maxed out with the default settings.

LoL. Neeevverrmiinnndd
is it possible to separate the lcd from glass without damaging it? my glass is shattered,but lcd is fine.
mine is also broken and i am just about to order the digitizer only, is it possible to replace only the digitizer?
Looking at these made me glance at my phone and I noticed.. My camera isn't centered on the back!! WHAT?!?! LoL
How hard is it to just remove and re attach the rear housing? my rear notification LED doesn't work and I want to fix it.

Backlight bleed or light leakage.

My Xperia Z Ultra has minor light leakage from the top of the screen. Visible at the top and also the top left and right.
Its not evident when the phone is held straight but becomes visible (these areas appear brighter at an angle and you can see a clear source of light) when the phone is held at an angle. I cant recollect whether I had this from day 1.
Its been about two months with this device.
Is this normal? I do know that minor backlight bleed or leakage is to be expected from an LCD screen but I thought that applied to bigger panels like monitors. But is this normal for a phone? All my previous android devices were Samsungs with AMOLED displays so I'm not sure whether I'm just getting worried over nothing.
To test this, take a pure white background at fullscreen and check the corners of the screen at different angles.
Kindly post your findings here.
Yup, I have it too. Not really noticeable unless I look for it though, so it doesn't bother me.

Is it at the top of the screen for you? Is it visible when you tilt the screen or when the phone is horizontal..like when placed on a table?
For me the top most area of the screen appears brighter with light shining through when I hold the phone vertically at a 45 degree angle or when the phone is on a table.
When I'm holding the phone straight on, directly facing it, it doesnt seem to show much.
