I wonder it this burn in is reversible because I know it is for plasma tv.

I just checked my screen with a flashlight app and thankfully I do NOT have any burn-in. I'd like to replace the title bar with a black one while I still have a chance to avoid burn-in. I haven't rooted yet; does anyone know of a way for black title bar without rooting?
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
I think the only way is to root. wish I could switch mine to black as well. but even still, then you will get burn in of the white letters rather than the dark bar. seems like no matter what it may happen.

for example the time in the top right corner, the M is always in the same spot whether its am or pm, and I can faintly see an M on my burn in.
[Nexus One Q&A, Help & Troubleshooting] NexusDro:
Unless someone program the notification bar to alternate between black and white periodically on its own.

I read it somewhere while I was doing some research on Plasma TV's vs. LCD TV's. They say that if you keep changing the color of the display, the burn-in will go away after a while.

Can someone make an app that can continuously change the colour of the screen where the notification bar is?
[Nexus One Q&A, Help & Troubleshooting] maxh:
Periodically altering the status bar color scheme between black and white is an excellent idea! I bet the program "tasker" could be used to do it (once rooted.)
[Nexus One Q&A, Help & Troubleshooting] liam.lah:
Small amount of burn in, tiny bit of banding on the top, nothing bad though.

May be from the times i had screen left on on charge. Then hit the trackball when i was asleep or something.
[Nexus One Q&A, Help & Troubleshooting] Old MuckenMire:
I too would love an app that changes the color of the notification bar without rooting. I'd pay for it. I wish Google would add this function in the OS menu. Choice is good.:)
[Nexus One Q&A, Help & Troubleshooting] musashiken:
Great... now I got slight burn in on mine as well... :(

Oh well, guess I'll turn on full screen with HelixLauncher 2 and leave it there with a dark background for another couple of months.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
I don't know if this will help, but I now just rotate the display to landscape every few minutes. I don't know if this will help from here on out, but worth a shot.

is this issue from using those pixels much more than others, or is it from having the screen on for long periods of time?
[Nexus One Q&A, Help & Troubleshooting] Old MuckenMire:
I don't know how I missed it but thanks for the helixlauncher mention.
[Nexus One Q&A, Help & Troubleshooting] musashiken:
Unfortunately it only works for the home screens. Once you enter settings or an app that doesn't have full screen, the notification bar will be back. At least it does help.

I'm using skyfire for my browser now as it can turn on full screen mode too. So I try to surf the web more often too :p
[Nexus One Q&A, Help & Troubleshooting] trinode:
So do we think it's pixel ageing and not screen burn as such?

I'm thinking ageing the whole screen may reduce it (though I'd have thought this should be done in the factory...)? (by ageing it I mean full brightness white screen for a long time).

If I squint really hard, I can just about see where my signal and battery indicator would be, but it's no biggie for me...
[Nexus One Q&A, Help & Troubleshooting] yongwk:
i have screen burns too... i only notice it after reading this thread...
[Nexus One Q&A, Help & Troubleshooting] Old MuckenMire:
somebody needs to add a disclaimer about reading this thread in the first post :D

On a side not: I contacted the developer of openhome and asked if he could add an option to remove the notification bar. I use openhome quite a lot and would love to get rid of that bar just for aesthetics sake as well as the burn in issue.

I much prefer openhome to helixlauncher and if he'll add this option I'll be golden.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
i have the burn in and never set my screen brightness to maximum. its been on auto the entire time. so i dont know if that's the cause.

i too wonder if this is pixel aging, or just burn in. is it something that could have been prevented during the "break in" period of the phone? or is this happening no matter what we do simply because those pixels are used much more?
[Nexus One Q&A, Help & Troubleshooting] jacka$$1:
I'm willing to bet that every single phone out there have burn-in issues. It's so infinitesimal that it's a non-issue. N1's just getting more attention because it's currently in the lime light.

Food for thought: Aiming for "perfection" is no fun at parties. Don't be that guy.
[Nexus One Q&A, Help & Troubleshooting] trinode:
never had it on a phone before, and I *would* notice.

I've had my phone on full brightness entirely white screen for over 4 hours now, and it seems to be less noticable, now I just have to work out if I'm imagining that....
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
haha keep us posted, that's a good idea. there is an app called stuck pixel fix or something that might be worth a shot if you're gonna test it for hours. its free in the market. actually its called JscreenFix.
[Nexus One Q&A, Help & Troubleshooting] cornwall:
Same thing here... :mad:

Noticed that today, on my three months old N1, notification bar...

Nothing to worry about though, as the bar strays on all the time. But when I drive, I use a navigation app and speed camera software (here in France, it's called "Eklaireur"), full brightness, and the notif bar stays on all the time... I guess everything came from that.

Will do the dead pix locator thingie a try. Hopefully it should help !
[Nexus One Q&A, Help & Troubleshooting] SirLegolas:
Someone take a darn picture of his burned phone already!!!!!!!!! I want to see what are you talking about :/
[Nexus One Q&A, Help & Troubleshooting] SBS_:
Think it would be pretty hard to get a picture of it, at least the way it's showing on my phone. Have to have the phone literally an inch from my face and hold it at an angle, so quite impossible to take a picture of.
[Nexus One Q&A, Help & Troubleshooting] bengrulz:
You can barely see there are two different shades of white when looking at where the notification bar was while using the phone in landscape mode.. It's more visible by eye, but not by much.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
Yes I'm almost positive that every nexus one has to have this issue in some varying degree. It makes no sense not to unless people really never have their screen on at all.
[Nexus One Q&A, Help & Troubleshooting] freeborock:
Well was on the phone with customer care (nexus one) and it should be fixed with the froyo update. Hope its not the update that's going around cause that didn't fix it!
[Nexus One Q&A, Help & Troubleshooting] bengrulz:
I really really really doubt that a software update could do anything to fix this. I think they just wanted to get you off the phone to be honest..
[Nexus One Q&A, Help & Troubleshooting] coolbho3000:

I'm on my 2nd nexus one with the same issue (only a week old). Guess it's time four a 3rd one!
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
Wait, your week old phone has this issue? That might change things as there is no way the pixels could be worn that quickly. Perhaps these phones are coming from the factory like this with burnt pixels already?
[Nexus One Q&A, Help & Troubleshooting] freeborock:
Thing is when I got my 2nd phone I hardly couldn't notice it until I installed 2.2. And its more noticeable now then the 1st one I had.
[Nexus One Q&A, Help & Troubleshooting] prophetjinn:
I can understand if the screen was brighter, but other than that i highly doubt that the software caused the issue that you're seeing. It's highly unlikely.
[Nexus One Q&A, Help & Troubleshooting] dogiedogie:
Quoted from http://www.oledbuyingguide.com/oled-tv-articles/oled-tv-vs-plasma-tv.html

"OLED TVs and monitors will have the advantage of no screen burn in."

But when I turn my screen to minimum [better], go on a white backgrounded page, indeed there is a burn in. The ONLY explanation we have been able to come up with is the power management of these top pixels, they are so used to being not at their maximum setting that they have become INCAPABLE of dispalying as brightly as the others.

EDIT: After checking my brothers 2 month old [compared to my 4-5], which also suffers the same problem, ive contacted HTC.

I will update you guys with their response.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
It's called image sticking and I guess I didn't link the pdf article but it talks all about it specific to amoled screens and how to design UI to avoid this happening. It's definitely real and definitely permanent.

Read this link starting on page 20.

http://data.4dsystems.com.au/downloads/micro-OLED/Docs/4D_AMOLED_Presentation.pdf

And ironically the notification bar has enough blue color in it which accelerates this issue since that color goes dead the fastest. Obviously many of us are indeed having this issue, even a pic was posted showing it. So in fact amoled seems to be WORSE than standard lcd screens.
[Nexus One Q&A, Help & Troubleshooting] PrawnPoBoy:
Yup. It's very faint but I also have some dimming/burn from the status bar. Its barely noticeable right now, but the phone is only just over a month and a half old. What happens in 6 months, one year, two years? Seems like it could become a real issue.
[Nexus One Q&A, Help & Troubleshooting] iodaed:
same problem here...
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
OK guys i am about to root my phone finally. all the youtube videos look too fun. so i called google support to just ask about my screen burn in, which they said they have never heard of before. no problem, i'm not really too worried about it. worst case i can send it in for a new screen BEFORE i root, then start using a black notification bar theme so the new screen will not get burnt in. but do you think its worth going thru all that trouble before i root while i'm still under full warranty?

i kinda think i should just root and say screw it. maybe at a later time i could even pay to replace my screen. or by that time a new better phone might be out. anyone have any advice?
[Nexus One Q&A, Help & Troubleshooting] JHaste:
I have had mine since the release day and there is an EXTREMELY SLIGHT burn in of the top bar... just turned on a flashlight app for white screen with full brightness and there was a very faint shadow at the top... hmm...

now i am wondering if a white notification bar is better because i have had black just about everyday since manup dropped his black bar back in Jan
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
So you've used black color the whole time and have this issue? Hmmm could you take a pic so we could see if it makes any difference compared to not using black color? If true then color might not matter at all, and its just the static image wearing out the pixels no matter what.

Once I noticed this issue it starts to get more noticeable as time goes on.
[Nexus One Q&A, Help & Troubleshooting] JHaste:
I took a picture but you could not see anything in it... like I said it is extremely faint, but it is there... it is more just the outline of the box... I can't see numbers or symbols or anything so actually I may be better off than other people are reporting...
[Nexus One Q&A, Help & Troubleshooting] PrawnPoBoy:
The "burn-in" that starts to occur really isn't burn-in at all. The problem with OLED screens is that each pixel will loose intensity over its lifespan and appear less bright. It's assumed that this dimming will occur evenly across the entire screen, but when you have a mostly white status bar always on screen in the exact same place, the wear isn't even. So what people are seeing on their phone isn't really the image stuck on the screen, but a set of pixels that are just not as bright as the rest of the screen. The same thing happens with an LED backlight of an LCD. It will look dimmer over time, but since it's a single light source for every pixel, it dims evenly across the entire screen.

The strange thing about all this is that even though this is known issue with OLED screens, it really shouldn't be happening this quickly. I read that DuPont had solved the short lifespan of OLED pixels and that they were able to get 38,000 hours before seeing half the amount of brightness, which is over 4 years of 24/7 use. People are seeing noticeable dimming on the N1 in only a month or two of maybe an hour or two of use a day at the most? Makes no sense to me.

Perhaps the OLED tech in these phones is a generation or two old (like the touch panel) and has a very short lifespan. It's a shame they didn't go with a nice IPS panel in these phones. OLED doesn't seem ready for primetime.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
Yeah its called image sticking and I linked the technical info earlier in the thread. It's very strange that it happens so quick on this screen. Maybe its a low quality screen.

I finally rooted last night and now run the black notification bar from desire ROM. Guess its too late to repair it, but can prevent it from getting worse.

[Nexus One Q&A, Help & Troubleshooting] JoshHart:
Weird, I actually do see what youre talking about, never would have noticed if you didnt say something, therefore I blame you. Haha, it is very very faint though and not something that ill be concerned about, Ive used a black bar for probably 90% of the time ive had the phone(since launch day).
[Nexus One Q&A, Help & Troubleshooting] tokyomonster:
I just noticed this on my phone the other day, and it didn't click that it was burn in. That explains why you don't notice it at all in portrait.

Oh well. It's slightly annoying, but only just. I can't imagine I'll be staring at solid white long enough for it to really be a problem.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
I feel so much better that I'm not alone so I don't have to worry about having a defect. In a strange way, if it happens to others then its "normal" and fixing it will just happen again.
[Nexus One Q&A, Help & Troubleshooting] NexusDro:
If it is really due to a low quality screen, then shame on Google and HTC for using such cheap material and charging us a premium price for the phone :(
[Nexus One Q&A, Help & Troubleshooting] dogiedogie:
I emailed HTC about it.

Lets just say they were rather insistent we talked on the phone..... even after I requested twice to do it via email.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
Well here's the thing. The screen in the nexus is the only 3. 7 inch amoled screen available on the market in mass production. It's made by Samsung and they manufacturer the only amoled screen of this size. And its only available with the pentile sub pixel layout. So its not like they had any choice to chose between a cheap quality vs a higher quality model. The only choice they had was amoled vs standard lcd. This tells me the amoled technology is just not quite there yet. Google obviously thought newer amoled would be the better choice for a cutting edge phone. Remember amoled is not cheaper to produce, its more expensive. If they wanted to cheap out on the screen they would have went with lcd.
[Nexus One Q&A, Help & Troubleshooting] maxh:
I still don't notice any burn in on mine. I average probably 1.5 hours of screen on time per day and have had it for ~2.5 months. I've checked with full screen red, green, and blue (and white) at medium and high brightness, with no noticeable burn in. Maybe I'm lucky? I'm still going to run a black notification bar in a week or two when I finally root.
[Nexus One Q&A, Help & Troubleshooting] k3vink3vin:
I will probably enable 360 rotation and start using my device upside down from now on :rolleyes:
[Nexus One Q&A, Help & Troubleshooting] codesplice:
The way I understand it, the color of the notification bar isn't nearly as important as the contrast between it and the rest of the screen. If you use a theme that has the notification bar, background, and menus using similar colors, then the wear on the pixels should be a bit more even.

I think a lot of people gravitate towards a darker background image, which would make the white notification bar wear out quicker. If you run a white (or light-colored) background, the "burn in" might be less noticeable. The same goes for a black bar and a dark background.

Just kind of my thoughts on the issue.
[Nexus One Q&A, Help & Troubleshooting] paratox:
if you use the "dead pixel detect" app for proofing burn in, try the following:

when holding the phone in portrait position you see the shades on top where the status bar usually is.

now turn the phone into landscape position (rotate to left), you will see the shades disappear on the phones top position. new shades will fade in on the landscape top position.

there is some burn in left on the portrait top position, but it`s not so dramatically like when you hold the phone in portrait position.

i think this app is not the best solution to proof burn in, cause it will fade in some shades of the non existing status bar.

try this on your phone and report the results. i think most of the posters in this topic were scared cause this behavior of the "dead pixel detect" app.
[Nexus One Q&A, Help & Troubleshooting] keet:
I've noticed fading of the pixels on the 'absolute top' (where the top normally is when it's in portrait mode) of my Nexus One, no matter which program I'm using, whether it be the dead pixel detector, the market, the gallery, et cetera. They might be less noticeable, or barely noticeable at all in some situations, and in different lighting, but I am convinced that the problem is consistent. It's quite disappointing, considering that I've had other mobile devices that never had such problems as the Nexus One did, and they're practically obsolete now.
[Nexus One Q&A, Help & Troubleshooting] Tech_Boy:
Just ordered the Nexus yesterday, and I think this will prevent the problem for all rooted users. And is what I am going to do:

xdaforums.com/showthread.php?t=638659
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
Yes that would definitely fix it and you would avoid the problem. Or I use a completely pure black status bar, or the desire status bar in a pinch.
[Nexus One Q&A, Help & Troubleshooting] goTouch:
My screen has a slight screen burn on top, possible made by notification bar. When the screen is all white I can notice it. I took a picture with a Sony T10 with macro on. You can notice that the screen top is a little bit darker than the left side of the screen. (If you can't see, try to look at this picture 2 meter away from you monitor.)

In normal usage it doesn't bother me, but I'm afraid it gets worst.

If all amoled screen is like this, for me LCD is better. Amoled is just not ready yet. If I knew about this before, I would buy a phone with a LCD screen.

Just to complement: My phone is three months old. I don't want to imagine it with 1 year.

Found this: AMOLED GUIDE. See page 20

Congratulations to XDA. XDA Android application maximizes amoled displays lifetime.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
I know it kinda sucks. But remember its not happening to any other part of your screen. Only the white notification bar. If Google didn't make this a static image everywhere in the OS then this wouldn't happen. Something as simple as launcher pro, which beautifully hides the bar, eliminates this problem. Or if they used black instead of white.

For the improved color of amoled, its a trade off that I'll gladly take for now. The tech will improve too.
[Nexus One Q&A, Help & Troubleshooting] maxh:
That's not burn in. I think it is a fade effect there on purpose in the software. It's only 4 or 5 pixels; nowhere near the entire height of the notification bar, which it would be if it were burn in. With the full screen "flashlight" turned off and the notification bar back, the 4-5 pixel fade is gone, right, and the notification bar is uniform? Yeah, I'm pretty sure the 4-5 pixel fade at the top edge in full screen display is a software thing, as burn in would definitely be the same height as the notification bar with a sharp line.
[Nexus One Q&A, Help & Troubleshooting] hackm0d:
Just read through this, and I'm taking precautions.

I've installed the Desire black bar for minimum burn-in, and use a Strobe Light app with multiple colours flashing on the screen so that the pixels get some, well, exercise (to put it very loosely). :)

I've seen LCDs with dead pixels completely cured after madly cycling the entire screen through different colours for a few minutes or hours, depending on how bad it was. Don't think the same principle applies to AMOLED though, since - if I'm not mistaken - each subpixel is an individual LED.

+1

Not really. Even with a flashlight app on I can notice this little fading, and my phone isn't even a month old.
[Nexus One Q&A, Help & Troubleshooting] goTouch:
I made that picture using Dead Pixel Detect application. With Flashlight application I still get the fade effect at the top (burn in made by notification bar).
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
No its not gone. It's there permanently no matter what you do. It's not a software thing, the pixels are physically degraded at a faster rate than the rest of the screen because of the static image of the notification bar and It's white color.

You are thinking of lcd screens where you could fix it in a few hours by displaying a different image. Amoled is not like that. And this particular issue in this thread is a permanent thing.
[Nexus One Q&A, Help & Troubleshooting] maxh:
I still don't think that pic above is burn in. When I put my screen on full screen white or any other color, I get that same 5 pixel fade, and it's been like that since the phone was new. If it were burn in, it would be 40 pixels high and it would end in a sharp line, rather than fading. With the notification bar showing, the top 5 pixels are the same color as the rest of the notification bar, so you know the fade effect at the top edge when displaying full screen white has to be software, not burn in.

I can't help but wonder how many of the reports of burn in are actually misinterpretations of a software effect.
