[Q] Strange ring on the gray background

I find a strange ring on the gray background, such as the background of the notification interface.
The ring can only be seen in dark circumstance and it won't appear on the backgound in any other color. I've run some screen test software to ensure this strange problem.
Is there anyone else found this problem? How does it comes?
You can see the ring in the pic. I turned the light off when took the pic

Is it possibly burn in? Many amoled screen owners have burn in, including me and hundreds of other nexus one owners. Is there something circular that stays in that location on your screen all the time?

It could be the wallpaper?

Yes if your wall paper has a circle in that location, that guaranteed that's it. These amoled screens do not like static images in one location, burn in is very common.

I'm sure that it is not cause by burn in, becasue I only use the nexus default live wall paper and none of my apps have a circle in that place.
Like I said, the most strange thing is I can't see this circle in any other background except the gray one.

I have the very same ring here, also only visible in dark environments. Looks like they are using vacuum cups to handle the display glass ...

ja, I also guess that is caused by the way of handle the screen.
BTW, your Nexus S is i9020 or i9023? It seems that the Nexus S sold in Germany is i9023.
If your device is i9023, than it will prove that the problem can be found in both Super Clear LED and Super AMOLED (my device is Super AMOLED).

I have that to.
But I only see it in the notification bar. I think its suppose to be there....

It's a i9020 imported from UK.

Did you ever figure this out? I have the exact same problem, my ring is the same size, but a different location

so how do we get rid of it???

Skyrocket camera reddish tint in middle of scene.

I've noticed that when using my Skyrocket camera indoors, especially during the day, that there seems to be a slightly reddish hue around the center of the photo. This is noticeable in the display while I'm viewing the scene, and in the final photo. I am using auto white balance. I also notice that when I view a scene under incandescent lights using auto or incandescent w/b, the center has a greenish tint while the surrounding area is slightly reddish.
The following photo of the off white wall was taken in the early afternoon with ambient daylight. I was wondering if others with a Skyrocket have noticed the same thing. I just want to try to figure out if this is a normal condition with this phone before I go back to the AT&T store to demand an exchange. Thanks.

That wasn't Kool-Aid, that was wine. Lol.
After doing some experimentation, I have discovered that the light pollution from my LCD TV and my PC monitor in a room with ambient daylight seems to be the culprit here. I am somewhat of a photography buff and understand the effect of different types of light on digital photography, so I tried turning my monitor and TV off, and the reddish tint disappeared. My real cameras don't have this problem, but I guess the camera on this phone isn't quite up to the task of properly adjusting to different light sources at the same time. Anyway, I'll just have to be aware of this whenever I take photos indoors.
I'm still interested in hearing about your results, though. Thanks.

Oops, spoke too soon. I tried it again this morning and got the same red splotch. Maybe the lighting was different earlier. Anyway, I did some more searching leaving "Skyrocket" out and came up with several threads about this in the Galaxy S2, and other forums. Seems to be a common problem with the white balance in a lot of phone cameras, so I guess I'll just live with it.

reddish hue in middle of scene in camera
Sorry to bring up an old post, but I recently purchsed this S2 Skyrocket and have seen the same issues. I was about to call AT&T for an exchange, but could I be safe to say, i just need to adjust white balance?
There has been no other replies so either you and I are the only ones and need an exchange or others are just not replying.
Hope others can chime in.
Thanks!

Video camera and auto focus

So we all know how great the camera is on this phone... However I recently went to a "rave" and was taking some video. I noticed that whenever a light would pass the lense the auto focus would try and do its thing and kept trying. Is there a way to turn autofocus off or adjust something to have this not happen??

Cant turn off Auto Focus, but what you can do is tap the screen in a spot you want to focus on, and it will re-focus on that spot.
But here's the trick. When its dark this is especially important. Dont tap on a spot to focus that has all dark colors, your best bet is to tab a spot where two very different colors come togeteher. For example. If somebody is wearing a striped shirt, say black and white stripes. As long as they arent running by or anything drastic like that, their shirt would be a good place to tap to focus, because the camera has the ability to focus until the connecting points (where the white meets the black) is sharp and crisp, not blurry. If you tap on a light, or on somebodies blue pants or white shirt, or tap on a wall or something where in the little box that comes up to focus, if there's no drastic range of colors, it wont focus very well. Look at the picture below:

}
The top right area is all black, tapping there, the camera has nothing to focus on. It needs to see the edge of something, make it blurry, then adjust until its crisp and clear. As its moving through its focus range, it will see those areas getting clearer and sharper, but once it starts getting blurry again, it knows its past the sweet spot and goes back to it.
Right in the middle of the picture is some person wearing glasses with their hands up and they are lit up like a light is shining on them. Tapping on this persons face where the glasses are is a prime spot, because there's a clear difference between the black glasses and the pink skin, in other words, there's a high contrast where as the blonde girl below her who's wearing a dark colored jacket, tapping on her chest where there's a flap of some sort hanging down, there's very low contrast, because the color of the flap and the color of the jacket are the same, its hard for a computer/phone to distinguish the difference on low contrast targets. The higher the contrast, the quicker and better the focus will be. Best spots to tap on are the lines that intersect the contrasting colors, such as the edge of the glasses where the color of the image changes from black (glasses) to pink (face).

I noticed this too. Tested out the video at a few raves and I constantly had to refocus. My Galaxy Note kept the focus without any issues. But this takes better stills and has the battery I need for 8-12 hours of raving.
Side note: Can't wait for Electric Daisy Carnival this year! 300,000 people and 118 DJs last I checked. I'll be out of control all 3 days.

I noticed it this weekend at a music festival. Every time a light hit it (or strobe lights went off) the phone lost focus and had to refocus. My Atrix was amazing at low light electronic festival videos, so it may be going with me to EDC while my One X stays at home.
Wish there was a solution.

Horizontal lines in blue and gray areas

Hi,
Two weeks ago, I bought the Moto G. It is a great device. However I made a strange discovery.
When the brightness is high, there seem to be horizontal lines in blue and gray colors like the
facebook icon. You need to look very close to see them. When I looked at the display with a
magnifieng glass, every second line of pixels where in a lighter colour as the others.
All images are very sharp.but still the pixel-lines can be made out. If this is normal, then I will
live with this.
Thanks for any information

That doesn't sound normal. Could you take a close up picture of the affected area? Anyways I would definitely request a replacement.

I just found a thread including a picture which exactly describes the issue.https://www.google.com/url?q=http:/...ds-cse&usg=AFQjCNGaI4cLfsNaFK0vygdf_32mc49XyA

I tried to reproduce that image for you on my moto g with the Facebook icon and this is what it looks like

As you can see it doesn't very similar to the picture that user you linked posted, so I do think there's a defect in your screen.

Thanks for the fast reply. My picture however is only an example for the effect. When I zoom into your picture, I can also see the horizontal lines in the screen. Especially in the right sie oft the Google search bar and in the battery Symbol. The whole screen is made out of horizontal pixel lines. So I presume that all moto g will be like that. But I am suprised that I can See the lines with my bare eye in a HD screen.

Hi,
today I received my cristal clear screen protector. As soon as it was on the screen, the issue with the horizontal lines nearly vanished.
I don`t know why that happend but a screen protector solved it for me.

I've noticed the exact same issue on my MOTO G.
And i'm very surpised to see horizontal lines on an HD screen. I have also a Sony Xperia Neo V with much lower pixel density (265 i think) and it's very crisp and smooth with no lines at all..
My wife has also the same issue on her MOTO G.
It's present only horizontally and when you look the screen in a slight angle upwards..No downwards. When i change screen orientation to landscape the 'lines' are always there.. but now vertical.
They are present in the 1280 side and not in the 720. i think that every second pixel line is white.. Like i have 640 pixels only. That's happening in solid colors background and especially in grey, blue and green colors (like in the green message icon, or most noticabely in the grey keyboard buttons and in the battery icon on the status bar).
That's very strange and i don't know if i'm going my phone to the service because maybe they think that i'm too weird looking for such small things with a very nice handset by any other means..
Thank you very much and sorry for my bad english

Can't see the picture but I might know what you talking about.
My F2 has also vertical "spots" in low light/dark conditions when there also dark content displayed on the screen.
I think it is normal for OLED Screens, although I must say it is quite visible on the Poco f2.

Yes it appears in dark condition specialy on grey, dark grey color and a lot of apps using it in dark mode so it's normal no need to change the phone

Yes exactly. I must admit it is quite irritating seeing those at first; these "shadow lines" are especially more prominent when the DC dimming feature is activated.
I had those on every phone with OLED Screens (Galaxy S, S2, S3 etc. you name it) and also on the OnePlus 6.
I assume OLED Screens are not perfectly balanced out regarding their illumination strength or there are slight impurities/imperfections in the panel, since these are organic light emitting diodes. But I don't really know why these lines appear especially in low light conditions.
Other than that it does not bug me much (anymore) since in most use cases the lines/shadows are not visible.
