Nexus software key burn in

[wtpanos]

Has anyone noticed residual imaging with the software keys at the bottom?

None at all. And my screen is on a lot, as I work 12 hour shifts and am always on the phone not working When I click on something in the app drawer I can see some shadows where the icons were, but it goes away pretty fast. Pretty much the only time my software keys are gone is when watching YouTube videos, and I've never seen any image retention where they were.

LED images will burn in after a long, long time; but burn-in of those nav buttons isn't going to be an issue over the expected life span of the phone.

I have an LED TV and have to be more careful: those stupid channel logos in the corner or a news channel ticker may burn in over a period of time, but an LED screen on a phone that will last me 2 or 3 years? No sweat.

Do you think your screen is already burnt in or something?

People see the "temperary" residual images from things and start freaking out calling it "burn in". None of your screens have any "burn in" unless you had your screen on for days on one steady bright ass image without it changing at max brightness.

Yes! I notice it all the time. Although, it's not the softkey icons it's the whole softkey bar. When watching a video that expands to fill the area normally occupied by the virtual keys, there is a very obvious section of the screen that doesn't match the rest of the display.

It's pretty annoying.

^This.

I see it all the time when the screen expands for video. I even see it around the softkey icons but it's not as pronounced. Very annoying indeed.

agreed. i see it as well but its not that bad. i have my screen on CONSTANTLY during my work day so i SHOULD see it the worst, and it doesn't bother me one bit while watching a full screen video.

i dont however, notice the actual buttons. its basically a section of the screen that is just slightly discolored

I tend to turn the phone upside when inside an app (like gmail), or counterclockwise so the buttons are near the earpiece quite a bit. Don't know if it helps, but figure it won't hurt.

What's causing the discoloration? Most of the navigation bar is black (off). So why is there such an obvious discoloration when that part of the screen actually gets used?

Not being able to see the screen, Barb: if you have burn-in, only the pixels where the nav buttons are would be visible all the time... even when playing a full-screen video, you would still be able to make out the ghosted shapes of the nav buttons. But that doesn't sound like the case here.

Could be a failing display. It sounds like a trip to a Verizon store is in order to me...

You could look at it as the rest of the screen burning in, and the nav-bar and notification bar being the only two parts that don't. Because the rest of the screen is actually being used, the blue OLEDs dim a little bit, whilst the unused ones in the nav-bar area are just about good as new. That means that the nav-bar area will be tinted blue because the blue OLEDs are healthier than in the rest of the screen.

I think there may be an 'initial drop-off' in the brightness of blue OLEDs, as well. So it starts at 100, and quickly drops off as you use the phone to a point where it decreases at a much slower rate from there on in.

That actually gives me an idea for an app which could fix this, which would show a blue image at the top and bottom over where the nav-bar and notification bar are, and then have the rest of the screen as pure black. If you left that on for long enough, perhaps you could dim the blue OLEDs in those areas enough to reduce the disparity between the different areas of the screen. Of course, if you do do that, and it somehow screws up your phone, we'll just pretend I didn't say this.

By the way, blue has the shortest lifespan of any OLED colour. Sort of funny, then, that Google would choose blue as their colour scheme from ICS going forward - though I suppose blue is the coolest colour (in every sense of the word).

Oh, and it isn't a screen fault. I have no idea how other people have managed to not have their screens burn in around the nav-bar (watching a hell of a lot of movies, perhaps?), but it's standard OLED behaviour and one of their most well-known drawbacks. It could be that I'm right about my initial drop-off idea, and they have just watched enough movies/full-screen stuff to have the blue OLEDs around the nav-bar go through that drop off as well.

Okay. I made a short video to test out the screen. Simple Color Test (R, G, B, Black, 50% Gray, White) - YouTube


With the screen at 100% the effect is still present, but not as noticeable. I sometimes watch videos at night before bed with the lights off (screen is dim). I guess this explains why I often notice the effect.

The effect is most dramatic when the screen is dim. I took pictures with the screen brightness at 10%. The pictures are (red, green, blue, 50% gray, and white).

The vertical bands on the red and blue shots are actually present, but I never noticed them until I took these pictures. The wavy lines are camera distortion.

I've observed it intermittently, but it has hasn't bothered me too much. Using the above YouTube video, I found it to be awfully noticeable with the blue screen...but it didn't show up with any of the other colors. Not on my phone at least.
