[Q] Ugly smudges on screen. Warranty return?

Hi everybody.
I bought my Nexus in December, and some time ago I noticed that screen looks ugly on certain backgrounds, mainly gray ones. So I did a little investigation and it turned out that I was right: picture looks mostly okay on primary colors, but grays shows terrible smudging. I took a photo of it. Do you think it qualifies for a warranty repair? Any of you noticed something like that?
I attach a photo, it's out of focus on purpose, because otherwise there would be a rainbow goo on screen.

The screen doesn't look good at lower light with certain colors that's just how it is..
The smudges look like someone wiped the screen with their thumb.

Screen was cleaned before taking photo. This rainbow effect is more or less visible on any background, but gray is especially bad. Even scrolling webpages is a bit annoying, because starting from top there is a pinkish stripe, then normal, then pinkish again... Yuck.

i have the exact same problem! Gray and white is the worst, and lower backlight is worse. But I realized this is mainly the glass top's fault, while i scroll a page, i can see those sumdges staying in the same spot!, don't know whether a protecting film will help or not.

joshdu1125 so I'm not alone then. I had a protective film on screen until yesterday and removed it because I hoped it was it's fault. Turned out it's not. Contacted Samsung via email, wonder what they will say.

Handtec said that some of the first phones (first batches) have worse displays than newer batches. I already sent my phone to them to be replaced.

screen issue
looks like its more or less same problem experienced by G.Note user, like myself..
G.Note Screen Problem Thread
try get "screen filter" from market and lower the intensity of color to let says 30%, check that same grey image, how does it look?..
My screen is much worse than urs if u wanna see... =.="
I am starting to think this problem is universal to all Samsung devices.. Zzzz

unfortunatey this is a problem with all samsung devices i suggest getting a kernel with color control such as francos or glados. its a lot better then the color control filter app and runs super smooth , francos kernel also pretty much doubled my battery life.

rey5757 you are right, less brightness = problem more exacerbated. I you have a photo of your screen, let us see it.
amcmearty I'm using Franco's kernel right now, but tried others too, to no avail.

just go to G.Note thread in my last post, at page 65. I don even have to take "out of focus" photo to see it.

This is a problem with the screen at lower brightness levels.. it happens to just about everyone that greys and whites look bad.

My phone also has the red stripe, and white is not uniform.

I doubt that Everyone is affected by this, some people claims they have perfect screen on the other thread.

The problem with this shadow thingy is that is varies greatly on difference screen.
The "Size", "Darkness", "Area" of shadow are INconsistent. Some screen have shadow on top area of screen, some have it at corners, some have it at lower bottom, some have it all over half or screen. Then some have it but barely visible(maybe this fall in perfect screen category), some have it but extremely obvious..
How is all these random quality screen fly out of Samsung?..

Not actually,
i want to know, something like very very less shaded area in white background,
i have in middle,
i have no problem about it, but u know its costly device, i m worried about it.
is that normal, its hard to see a shaded area,Its in middle, but when i see from far, then it is noticable,but hard again...
are all amoled not plain background?

yellow tint
I have that yellow tint that the link is describing due to the glue during the manufacturing process. I'm able to see it when looking directly to the screen. When the screen is slightly angled away, that yellow tint is gone. I hope it will be resolved on future updates.

So, is that Not issue? :cyclops:

it could be a screen burn in ...because of keeping the display on for a long period...like during navigation for long time
use app like display tester from play store to try resolve the burn in

No, i use my phone for calling and sometime gaming, but not much screen on..
is that,glue between the screen itself and the gorila glass?
someone told me that..

Can't say what's your problem without any pictures but yes, AMOLED displays differ from device to device, and it's still immature, unlike LCD displays.
And yes, mine has Yellowish tint too.

This can only be resolved with a color temperature change, up to now im still wondering why the color temperature on the Galaxy Note 2 devices vary so much from phone to phone and no its not the glue. From where I live this is valid with in the 7 days of replacement provided that the next unit they open up is not yellow. But if im in a pitch black room or no 'warm' light sources there are no traces of this warm color temp.

Mine has no yellow tint, mine looks like middle area of screen is grey shaded, I checked, protector is ok, but screen middle area is very slightly shaded. Very difficult to see, when we scroll fb or youtube(down to up) then its noticable... most in plane white background...
I hope someone understand my fail English. .

Thats obviously a defect, have it replaced.

so, thats a picture,
shows that middle area of screen is grey shaded,
is that Normal?

have it replaced.

Like I already said in another thread to your query, this is normal. If you can't distinguish this from the naked eye (during normal use), this is definitely normal. I'm sure you are keeping the display in low brightness; this brightness uniformity issue exists on virtually all AMOLED displays, and the Mura Effect does have some attribute to this as well. Rumors say that the Samsung's Flagship Devices this year (2013) might feature an SLCD3 instead of AMOLED. Might indicate that AMOLED displays still need further refinement. If the shade is not so prominent, you should not worry about it then. Every Note 2 has this, those that say they don't see the shade are not looking close enough. I call this AMOLED phenomena a Samsung-kind-of-thing for a reason.

HTC One M8 backlight bleeding problem?

I got my HTC One recently (last Friday) and it was a perfect phone! no problems whatsoever...
Yesterday i was playing with the phone with a colourful background wallpaper from HTC and i noticed light bleeding from the top (hold it in a angle and you can see a light bar shine through like this:
http://forums.androidcentral.com/at...een-issues-uploadfromtaptalk1367129491252.jpg
It isn't that big of a deal but for a phone that costs over 500 euro's here in my country.. you expect that it is build properly and backlight bleeding on a phone at this price!?
I compared 4 HTC's in the store and they all got the same problem

GPe dims the edges of the screen, so it's harder to notice if it's there. I haven't ran sense in a while so I can't tell either, but I can't notice this light bar effect on my phone either. So it may just be that batch of phones.

Got it in in my bottom right corner... very minimal though

Wow, that's massively anal lol.

mine was the whole top screen.. but it doesn't matter, that's just HTC right..? They're known for the screen bleeding, haha..

I've been having this issue on the bottom of the display. It makes the nav buttons look funny and full-screen content is washed out.

Here's mine. Italian H3g branded:

That light bleed above is probably a bit excessive bit you guys have to realize that all LCD screens are going to have some light bleed. You can usually make it less noticeable by using a lower brightness setting. If you are really anal about the slightest amount of bleed you should really be looking into phones with AMOLED displays. That said, if the light bleed is washing out the nav bar at reasonable brightness settings you should try to get it fixed or replaced.
My M8 has some bleed on the top left corner at normal brightness and I'll notice it across the entire top if I go full brightness in a dark room. At normal brightness it doesn't bother me at all.

Washed Out Screen Color?

I'm writing to see if anyone here might have the same issue I'm having with my Note 4.
When it's bright outside, sometimes, the screen not only amps up the brightness, but for some reason all the colors on the screen appear really washed out. Facebook's logo is now neon blue, Evernote is like a pale lime, etc. All the colors are horribly ugly. If I open an app, or the drawer, the screen goes back to normal color, still bright though.
This ONLY happens (thus far) when I've turned the phone on while being in direct sunlight.
If I manually turn my brightness level ALL the way up, the colors still appear fine, I can't make the screen wash the colors out like that manually (not with brightness levels or adaptive display modes).
This also doesn't happen every time I wake the phone up while in direct sunlight, but about 50% of the time.
So, anyone else have this problem? Is it normal, or should I try to get a replacement? Course, since I can't replicate it on demand that will be a PITA.
Thanks

Happens to me as well. I even went to far as to disable the "dynamic screen adjustment" or whatever it is, and it still happens. Just like you said, only in direct sunlight.

It's too make the screen more viewable in direct sunlight.

washing out the colors is normal in order for the phone to be bright enough to see in direct sunlight. I, for one, love that they did this because i can see the screen perfectly in bright sunlight.

I'm with you on this one, I think it's an awesome function. Heck when I found out it did I was showing everyone lol I have noticed that it's only sunlight cuz I tried using my note 3 flash light to do the same thing but to no avail.

Yes if you have your note 4 set to auto brightness, in direct sunlight the phones backlight will push the brightness all the way up to 750nits of brightness. It will wash out the colors, but it makes the screen very visible in direct sunlight. I personally love the feature, no need to cover your hand over your phone to see a text message or something else anymore. If you don't like, like myself, I manual adjust brightness myself. Half brightness is plenty bright for any other time of the day.

This happened to me yesterday and I thought my phone was going bad. It was a wtf moment for sure. Glad to know it's a feature and not an issue with the screen. I turned the screen off then on and it went away (might have been walking indoors).

I had this happen in the day time while I was in the car multiple times, so I just turned off the automatic brightness, solved my issue.

This is the first phone that has ever been bright enough for me to read books with in the noon day sun. So I'm loving this feature bigtime. I think the automatic feature could use some fine tuning because indoors it dims the brightness too much for me but otherwise... loving it.

Freaked me out the first time it did that to me outside, but quickly realized it was on purpose to make it more viewable since it was so bright outside. Love that feature tho

I love that they did this. 1st phone I've had that I can easily see the screen in direct bright sunlight. Good job Samsung.

I was shocked when I first saw it this morning... then did a google which led me here... thank God it aint faulty...

I think I have this issue but idk. Dark pictures on my screen show horrible and like blocky when there's blacks. The Samsung boot screen has a yellowish greenish tint to it. My colors look washed but it isn't horrible just the dark colors and blacks get to me

Question Hollow screen sound ok, but..

.. is the sound u get when tapping the screen also changing depending on where you tap the screen; meaning it sounds more low-pitched in the middle of the screen and more higher at the top and bottom?

Jup. As this point I'd call it common knowledge, we have talked about this on XDA for about 9512 times already^^
We even have dedicated threads, the search engine is your friend here.
It has to do with how the screen has been bonded to the edge of the frame and what lies underneath the screen. It's also present on quite the number of other phones, like the new IPhone 13s.

And the beat goes on

thanks guys!
so lets get on to another screen issue (since i cannot find a display thread here): do u also have a reddish tint as soon as u slightly tilt the phone?

Nope, not at all. I just checked most colors and tilted my phone in every direction, and for some odd reason I can't seem to find any sort of color tint. Even my white stays white in a ridiculous tilt, which never happened before with a pixel phone. All my previous pixel phones went a bit bluish when tilted. .Maybe my eyes have gone kaboom sh*t crazy, or I won the lottery ticket of this years display.
Some people here claimed / talked about a yellowish tint of their display, even though that was more of a general sort and also present when the phone was not tilted. I'm not able to reproduce that, so there is not much more to say.
Do you have a screen protector by chance? That one might be responsible for tint if tilted.
