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

I'm actually starting to get ghosting when I hide the keyboard

Does it go away over time just as it appears at least?

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.

S3 Screen

I don't know much about differences in screen besides what DPI and resolution is, but yesterday I was looking at some pictures and icons on my S3 and iPod 4gen and I noticed that the iPod screen was much much brighter than the S3. And because of that I was able to distinguish gradients and textures better.
So my question is, is the screen on the S3 dimmer than on purpose or is my screen defective.
-- just in case anyone was wondering I had both devices on full brightness.
--something I noticed was that if I put the iPod at half brightness, then that would be about as bright as my S3 on FULL brightness.

Did you try turning the brightness on your s3 up?
Edit: oops I see that you did. I dunno take it to a store and compare your screen to another s3.

Yes. The screen is dimmer. Samsung cut the maximum display power to 1.3 watts allowing for a longer battery life because of how big the screen is. Also has to do with the candelas per sq inch on a screen.

Ah I see. Is there a way to maybe to make the screen brighter some how by increasing the voltage or something.

You are comparing apples to oranges. The S3 uses samoled+, which presents blacks much deeper and whites so so. This makes for brighter whites and not so deep whites on the crapples devices giving the illusion of brighter screens. Just like comparing a plasma to an LCD. Yes there is an app to make the screen brighter, and you must be rooted. Just install the app and run it, must be clicked once per boot to work as it runs a command in the interactive shell.

Thread cleaned a bit.
Always fond of this saying: "Work the problem, not each other."

Has anybody else used that apk? Does it work? I don't want to mess up my brightness levels using it. I should be able to reboot and go back to normal but still cautious about trying it.

I just installed it and ran it. I granted it permission but I don't see any difference.
Thanks for the info on the screen by the way

You have to have autobrightness disabled and turn the brightness all the way down before running it. I am using it and the results are blinding !

Lol why do you need it brighter? It blinds me on full brightness. I always keep my half way and it's perfect.
Sent from my SGH-T999 using xda app-developers app

I still can't get it to work. I turn off automatic brightness, then lower it all down and run the app, then increase the brightness back up and still the same.

Black lines on screen in dark colors.

Guys everyone test ur phones do its a dim light or a room... now open a fully black photo or a video.. a lot of smiled screens have these strong spots or lights when ur looking at ur screen in the dark.
Or download an LCD test and perform it in a dim/dark room...
I want to know how many of ur screens are effected because a lot of people are reporting this issue and when they exchange their phones they still get the same problem.
For me its an issue since I payed $600 for it and would expect a flawless screen.
Sent from my SGH-T999 using xda app-developers app

I've noticed two very tiny spots that are darker than others when brightness is down and the only thing on my screen is backlight (such as when a game/youtube is loading) but no bars or anything that has really caused me undue annoyance.

Good luck that is a Samsung trademark. Dealt with it with the S2 now the S3. For everything else the phone does I don't even worry about it. But I also go my phone from Tmobile free so I am not too worried as long as it works

So should I get it replaced I bought it for 600 from a tmobile store just a few says ago.. or is it likely I will get the same thing again.. (those black spots/lines)

Just keep it and enjoy it. Most if not all have this problem.

Most super amloed screens have this problem. I knoticed it too when I first got my phone but I learned to accept it because it really isn't visible unless you do what you mentioned above.
Sent from my SGH-T999 using xda app-developers app

Ok I understand but mine doesn't have a little. It has 2 big lines down the screen and a bunch of stains all around... is this considered too much of a flaw with amoled?
Sent from my SGH-T999 using xda app-developers app

Do you see it during normal use or just when you put it in those conditions? Because, I'm sure 90% of the phones will have it with those conditions. If you only have it under those conditions, then ignore it, because, as I said, 90% of S3 owners (AMOLED owners) will have it. If you see it during normal use, then replace the phone.

defective led notification?

I don't know if mine is defective or not. But the color isn't pure white from what I see on the nexus 4 in videos. I think it should be the same right?
Its more of a yellowish tint?

There is no spec on the color of the light, and what the nexus 4 does is irrelevant. If it lights up at the right time it is fine.

People are honestly finding every last thing that they can to complain about this tablet. Did you buy the tablet to look at the notification light, or to actually use the tablet?

I kinda agree with what you say, except that when you buy something "expensive", your expectations are high and you want something perfect (i don't own the nexus 7 so i don't know how should it be) but if the led isn't showing the right color, it's something to care about, though it's a small defect..

I also see what you're saying, but like the poster above me said, there is no specification on the notification light, so there isn't much you can do. Some people have notification LEDs that don't even work apparently. Since the reality is that this generation seems to be having many build quality issues, it doesn't seem like it's worth taking the chance to return it, even though OP probably can't over this issue anyway.

Mine is more eggshell white but remember its only a ~$200 tablet and LG probably uses different LEDs that may be tuned to a more brilliant white
Sent from my Nexus 7 using xda app-developers app

It's funny I didn't even know I had a notification light until one day I left my tablet sitting there and got a notification while the screen was off. So I believe it only works when when screen is off it's the only time I've seen it go off.... It's on the bottom of the screen right under the button bar (back, home, and recents button). I have been flashing ROMs, kernels, modifying my system to my liking, and trying different things so I never even noticed the light lol.
