Galaxy nexus washed out screen

Hi. I ordered a galaxy nexus for my brother from expansys and received it today. The screen on it is not nearly as good as the one on my own device. The colors are really washed out and the greys are green. It seems like the gamma is really turned up. I rooted and flashed aokp and tried adjusting the colors and gamma but if you try lowering the green gamma settings, the whole screen turns green. Is there anything I can do? If not, Does anyone have any experience doing exchanges with expansys? I'll unroot and relock the phone of course. Any help would be appreciated

Thanks for the replies. I'll contact them. Did any of you buy one from expansys? Just want to know how they are with this stuff

i would definitely try to exchange it, if you can't then use a kernel with gamma control such as leankernel or glados (which i'm currently using), adjustable by editing sys/devices/platform/omapdss/manager0/gamma
mine has the washed out screen issue and editing gamma to 7 or higher makes it much better looking, but not perfect (still a lot of purple at low brightness)

Please refer to the defective screen sticky in the Q&A section, that can be found here, or one of the other threads in the General section already discussing screen defects.

Whoa, what's this about screen burn-in?

I saw the other thread about it....I know it's normal, but is it eventually going to be a problem as far as like watching movies goes? It kind of seemed like the burn-ins were only visible when the background was all a solid color, via a pixel tested app....?

If it gets bad, you'll have a ghost image that you're going to notice all the time, especially since you're now paranoid about it. Basic preventative measures will keep you straight, though, it's not as though it's a recall worthy issue. Max out your brightness and full screen a solid white screen for a couple minutes now and then, hell I'm pretty sure there's actually an app that'll even invert your nav bar, and notification bar for safe measure. Nothing to sweat over, enjoy your phone
I777 gets it done, gnex just for fun

Screen burn ins do not go away over time. That is why it is called burn in. The image is "burned" onto the screen leaving a ghost of what was there.

Well the images could be burned in because they're still being displayed a lot, like the navbar or the keyboard. Like a sunburn, it stays if you stay in the sun, but goes away if you get out of the sun for a week or so.
That's where my reasoning came from... Ah well, millions of people have this "problem", I guess it's really not a big deal.
Thanks for the replies!

Here's the app that fixes it.

It was just said that burn in is permanent....

Some isn't you can fix some by displaying only white color or things like that

I got my GNex yesterday and am already seeing some minor screen burn in. It looks like a bunch of rectangles along the lower half of the phone. I have 14 days to return it for another one. Should I do it now or wait as long as I can before starting the process?

It's NOT technically the burn in of the lcd days where an image was truly burned in. It's kinda like reverse led fatigue. Take the navbar for example, the leds have much less less usage time on them. So when the full screen is used the leds that are part of the navbar will burn brighter giving the appearance of burn in.
good day.

I see, so the burn in spots are actually less worn than the rest of the display?

Burned in images of stock arangment of apps?

So i just bought a used galaxy nexus and have been using for a little while and i keep noticing that it looks the stock arrangement of apps on the home screen are liked burned into the screen. Like i can see them everywhere i can go and more depending on what color the screen is at. Its not software because i booted into CWM and i could seem them. Is this a defect? Or just the nature of the phone? I have tried to take some pictures but they didn't turn out to great......
Here is a link to the high quality version of the picture https://www.box.com/s/bv84z7gu0dsltgzorevi

Normal good sir.
Pretty much any used Galaxy Nexus will have some burn-in, as the display is AMOLED. Happens with all of our Galaxy Nexuses, I guess we kind of just accept it though. lol
The way the Nav Bar sits, we all will probably have it burned in sooner or later, many already have it...
Just as well, look at a black background with the display on and you'll see blotches on the screen, also normal. There's actually a sticky here about what's normal and what's not.

Hmm not experiencing that. Its just as responsive when I'm not holding it.
Sent from my Galaxy Nexus using xda premium

Maybe when you are holding your phone or putting it down, different parts of your fingers are touching the screen, and the sensor responds differently to them.

Don't know but I can for sure feel the difference... sometimes I need to press 4 or 5 times before the phone recognizes the input

Same here except mines doesn't matter how it's being held. I also have to apply force on the bottom section of my screen all the Damn time to apply a touch.

Do you guys have screen protectors applied? There was one brand in particular where the screen protector would cause the screen to become quite unresponsive especially at the bottom of the screen. If that's the case you might want to change screen protectors or just go commando.

I have had my gnex since release day with no screen protector and not a single scratch to this day. As long as you are somewhat careful as to how you handle your phone you will be fine. To me the screen protectors on the galaxy nexus seem awful and huge finger print magnets from the pics I have seen, and that would drive me nuts.

The nexus one had an issue with this and it had to do with grounding when the device was held which would allow the touchscreen to work well. As soon as your not holding it touch response goes to s***

I don't think a phone with an all-plastic body like a Galaxy Nexus would have a problem with grounding?

When the screen protector was off, did you try using the phone and see if the sensitivity improved? If it didn't at least you could rule out that the screen protector is the problem.

I've known a few good people with this problem, but most of them have hands that become moist easily. Perhaps this is causing it, no?

I have the same problem. When I put it on the holder at my work and start watching YouTube my back button I have to press 100 times it losses sensitivity

I don't get that at all. I have ****e reception here, so when I text and stuff I put my phone down on the speaker by the window. It always seems to work just fine with me pecking away.

now i'm starting to have issue were screen is totally unresponsive and battery pull is the solution
this is not normal

4.2 Daydream and it's effect on battery

Daydream sounds awesome. I have it displaying the clock while it's charging. My questions is, how much drainage is it doing to the battery while the screen is on?
For instance, if i had the screen completely off, I would have reached 100% in 1 hour rather than 1.5 hours since I have day dream working...?
So how much drainage?

For me it charges at the same rate with daydream on(of the wall)

What concerns me more than charging rate is screen degradation, AMOLED screens degrade over time so I wouldn't keep my screen on if I wasn't using it

Are any of the daydreams even static? I assumed that the reason the clock bounces around is to avoid things like burn-in.

The standard one is static, some of the third party ones are not. I really wouldn't worry it too much.

Check again, the standard daydream clock is not static, at least the digital one isn't.

Sent from my Galaxy Nexus using Tapatalk 2

it isn't just about burn in... amoled pixels do degrade over time like another user said,and this is a dangerous way to screw up your screen much quicker.
not a good feature to use on our phone imo

It takes a long time for that to happen there are plenty of people still rocking a Galaxy S1 and the screen is fine but I'm not saying there's no one with problems but I doubt it would mess up by using daydream
Sent from my Galaxy Nexus using xda app-developers app

Ya, the digital clock is not static. However, I would worry more about the navigation bar because that thing is gonna stay in landscape mode and I already got a nav bar burn-in in portrait.

depends, is it on overnight? Say you sleep 8 hours that's 8 hours extra the pixels are on per day.
Do the math, it would add up quickly

burn in only occurs when you have an static image in the same place all the time.. daydream move the clock around the screen every few seconds, and with the black background most of the pixels of the screen are off anyway.
so no, there is no danger using daydream.

I'm not talking about burn in....
do you not know about the degradation of amoled pixels over time?
you could end up with dead/stuck pixels a lot earlier than expected.
