Super AMOLED screen "Burn-in" problem observed

I own both Samsung Captivate and Focus, both devices have SUPER AMOLED screen. Both devices have burn-in problem after months of usage.
Captivate:
I could see the notification bar on top of the screen with the fuzzy clock and battery indicator burn-in to the screen with very pale color especially very noticeable with a white screen! I also saw AT&T stores had these demo units experiencing the exact problem! I then called up Samsung to replace the Super AMOLED screen. Now it's fine but very annoying.
Samsung Focus:
I just got mine in Dec and didn't use a lot on that device. There is a very good reason why WP7 has to hide those status indicators on top to prevent Super AMOLED screen burn-in problem. I also checked out the demo units in AT&T stores, all of the Focus had Windows Phone 7 logo burn-in to the screen at the top left corner due to the static logo constantly playing on the demo mode.
In conclusion:
SUPER AMOLED screen's quality life-time is still short compare to LCDs. Given about 2 months of usage, 8 hours a day with static image such as notification bars for example, burn-in issue is inevitable! In real-life daily usage, give it about 2.6 hrs a day, your screen will be burnt after 6 months.
NEVER USE SUPER AMOLED SCREEN WITH STATIC IMAGE!

On my phone the screen isn't on for very long periods. Even when I am talking on it if near my face the screen is off.
How does this compare to your experience?
Does a phone in demo mode have the screen on constantly?

The only reson OLED isn't so widely used is because of its limited life span (especially on blue color). From what I read in the past, it is very difficult to get blue channel pixels pass 2,000 hours of life span. Not sure if AMOLED or SAMOLED made any advancement in this area. So, the precautions should always be taken. Let your phone screen on 8-hour a day is not a good approach. That's why there is a setting to let phone go into sleep and turn off the display.
My Captivate has been working flawless since August 2010 with zero image retention or burn in.

How many hours per day do you keep your screen turned on? I would give that minimum 480 hrs with static image to experience burn-in. No need to wait 2000 hrs of life-time in Blue Channel in AMOLED.
The life-time of the entire Super AMOLED is here and I'm also being conservative: 480Hrs to start to get burn-in issue using AT&T store demo units as reference.

I use skype and bluetooth headsets alot, so screen shut down may not happen at all until i manually shut off the screen. Moreover, using GPS navigation will definitely cause burn-in problem with static images such as the miles, eta, notification bar, clock, battery indicator, etc.
Android is just not a good OS for Super AMOLED. WP7 on the other hand is for Super AMOLED.

I'd estimate less than 30 minutes total per day (only counts screen on time). So, 480 hrs should let me use my phone for 960 days, or way beyond my tolerance for an *old* phone.
If I'm sitting in a meeting broswing internet or reading news using some apps, almost all of them are full screen and won't necessary have static images on the fixed locations.
Turn the brightness down (I use auto brightness setting) and don't let the screen on for extended period. You will be fine.

I have to agree. The metro color schem (black in most of the screen) is the best way to reduce AMOLED battery usage and lower the potential burn-in risk.

I have both devices and neither or them display image retention. What method or program are you using to test this?
I downloaded a flashlight app on the captivate and on the Focus so I could turn the whole screen white. I also adjusted it to other color,s still see no burned in images.
I've had my Captivate and Focus since day one when they were first released by AT&T.

Go to any AT&T cooperate stores to check out all the burn-in screens. For captivate I use screen test. It cycles from white, black, green, red, blue, and other pallets. I can garauntee you that all Super AMOLED screens are the same given static images and keep the screen turned on such as notification bar, full battery notification, GPS app.
If you don't have any burn-in problems that means you haven't used the screen long enough even you got your devices since launch.

The key here is to keep the screen-on time as short as possible. For normal usage, it will be fine. Will it have burn in 2 or 3 years down the road? Sure, but I probably have to dig it out from the bottom of my drawer to check it out by then. I'd rather enjoy my sharp crispy and colorful SAMOLED for 2 years than worry about burn-in and settle for murky, low contrast and washed out color of the LCD screen for 2 years.
Store demos are the worse case senario.

Very true! But still people really need to beware of their SUPER AMOLED screen. But for gamers...... make sure don't allow a static screen staying on for too long.

Well, I was reading an email yesterday on my focus and noticed that the smiley message icon was like a little ghost in the background. I also noticed the circle/arrow icon. I use orange on black mainly. I moved the tiles around a bit, we'll see if it goes away.

No, it did not go away. It's only visible on white screens, but it is definitely there. I guess I'm going to drop by the at&t store to see if it's a warranty issue, but I highly doubt it. My guess is I'm stuck with it. Since I use the black theme it's not a huge issue, but when I switch to the white theme it looks pretty awful.

Why beware? Image Persistance can happen on any screen that is left running static for long periods of time. In most of the AT&T stores that I have been in the demo units are set to stay up and running for which I can only assume is to attract people. This will cause the image persistance that you are talking about. These phones screens also get used a lot more than your personal cell will.
Use your phone and don't worry about something that may or may not happen. In two years or less you will likely have a new one anyway.

Hilarious!
This reminds me of the times where projector tvs and lately plasma tvs exhibit the same not-suitable-for-gaming problem! LOL
That's one of the reasons I got the Motorola Atrix with its LCD screen!
My previous smartphone was a Nexus One and even though it didn't exhibit ghosting problems, I always tried to use it as little as possible and used the screen on its dimmest setting.
Now I can leave the screen on at full brightness for hours (like for GPS driving for instance) without any remorse!

I have the the imprint of Internet Explorer Mobile's chome burned onto my screen.

They have been trying very hard in the past decade or so. The main problem is the blue channel pixels' life span. Most companies have ditched their effort and move to other technologies. That's the main reason why there is no consumer TVs made of the OLED screens other than the $4000 Sony 14" OLED tv.
Unless there is a scientific breakthrough, this situation will remain for years to come.

Has anyone dealt with Samsung Tech support on this issue I just got off the phone with them and they wanted me to do a Hard reset. I tried to explain that this was a physical issue, but they still wanted to follow their script.
Now they have sent me a label to send it off but want me to remove my SD card. It ismy understanding that this card is bonded to the phone and cannot be used in a replacement phone if they send me one. I am going to call them back ut based on my previous conversation I am not holding out hope that anyone there will know what I am talking about.

Nexus 4 annoying visible IPS sensors

Hey guys,
I've had my nexus 4 for a week now and I am super pleased by it. The phone runs like a dream.
The only issue I seem to be having is that I can see the IPS sensors even with the screen on!.
I'm talking about the little transparent-gray squares all over it, not about the super awesome dots that you can see with direct sunlight.
This is flipping me out!
Is anybody else having this problem with it?
I can't appreciate the beautiful screen because of this.
Also, when displaying single color frames specially dark ones, like on the clock app , the colors are not really solid.
I get this vertical stripes that are approximate to the color but not quite it.
Im posting a screenshot but I don't think that youll be able to notice it since it may be a hardware problem.
Sent from my Nexus 4 using xda app-developers app

That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Question to the OP. Do YOU see anything wrong with those images, or is it a hardware problem? I can't see any difference between your screen shots and my phone.

Damn it man, now i see them too -.-
I went to the clock app, and i can see some stripes on the left but mine are vertical.

Haha Dude that's the digitizer. Don't worry. It's all cool.

Chill out people.. Its just the digitizer that you can see, so close to the screen for better touchscreen responsiveness. The most likely reason you can still see it with your device screen on is that you have your brightness too low.. Put it up

even amoled screen are also the same

When I first got my Nexus4 the weird screen was the first thing that popped out at me. Between the visible digitizer matrix that glints when it catches the sun wrong, to the odd rectangles that can be seen behind the screen I was initially bummed and thought about returning the phone. It doesn't even bother me anymore
This is my 8th android device and the first one that has a funky screen like this, but it really isnt a big deal. Under 95 percent of conditions it looks really nice

I have been able to see the digitizer on every single capacitive screen i have ever owned.

@David_Azar I have to agree.. initially I was disgusted by how prominent the digitzer pattern was, I've never had ANY screen show it as much as the Nexus 4 does.
However, the vertical stripes you're referencing is commonly referred to as "banding". I have this on my Nexus 4 as well, most visible on grays (especially darker grays).
I have been doing some research and I believe the banding issue will reduce over time. If you check your screen when displaying a white background at max brightness, such as gmail or chrome browser, you should see a slight yellowing of the whites. It appears this can be due to the adhesive they used to glue the digitizer to the screen not curing completely. After several weeks of use, the heat from the processor will help cure the adhesive causing the yellow to disappear after a while.
I cannot say for certain that it will completely resolve the banding issue, but I have noticed that the worst banding is in the areas where the yellow tint is most prominent. I have also been testing my display every day to monitor any changes, and I am happy to report I do see a minor reduction in both the yellowing and banding (I've only had my Nexus 4 for five days so far).
Give it a couple of weeks, run some intensive games to get the processor to heat up every day. Keep brightness at max for the next few weeks and let us know if you see any improvements.
As for the pattern of the digitizer in the glass.. it's not going anywhere so get used to it. I don't like it much either but it seems to be less prominent once you start becoming used to it.
Good luck, let us know how it goes

Hey man,
Curiously enough I've never had the yellow tints everybody's complaining about. I'm used to The digitizer matrix ( rectangles) buy at first it was really weird. I was coming from a non HD display ( a RAZR Maxx) so naturally, I expected that my N4 would have a perfect screen.
I've had my N4 for almost two months now and the banding has not reduced. I made some research over the last month and I found that with some kernel settings for saturation the banding is reduced. I'm not sure if it is really reduced or the clear gray tones that have the banding just don't appear anymore because of the saturation.
The Trinity kernel reduces this a bit but like I said, your screen will look life a f*** ing AMOLED.
Right now I'm using the kernel provided by the 123 FAUX CLOCK project. I'm using the LG factory presets and for the most part I'm really happy with the screen. If you or anybody else comes up with a different solution, let others know on this thread.
Peace brothers.
Sent from my Nexus 4 using xda app-developers app

Just for kicks, if you stop by a T-mobile location compare your screen with the display model and see if you can spot the yellow tint on either screen (on a white background)
I will update this thread with my phone's progress (or lack thereof if it stops improving).

I get banding issues also, more noticeable in grey backgrounds; but I can I see them in other colors if I look hard enough
I use a dark black theme to avoid looking at those bands

I can say this. I've had a ton of devices..latest was s3 and I'll just say I'm stoked to have IPS over pen tile. Just knowing HD was plagued by this alone was enough for me to ditch Sammy all together especially after seeing rgb on note 2 was no better. This is my opinion of Samsung's design ...I know why they chose it but I can't and won't buy another amoled until they get another tech in order. So now I say kudos on IPS but I'm surely a screen purest and I found these hardware screen/digitizer artifacts you speak of and to me its so much less noticeable. Your not alone. You just like good clean HD like me. Lol HTC one should be a nice one to check out...
Sent from my Nexus 4 using xda premium

That would be a little like kicking myself in the nuts. Nothing good can come out of that.
If I spot the yellow tints once, then I will always look for it. I hate doing that with the banding but it's an automatic thing.
I dunno why but it really bums me out whenever I have a problem with my phone.
Let's keep posting of someone finds a solution or something .

I've got the quite visible digitizer rectangles too. In anything less than a dark room if the phone is not on a perfect angle they are visible.
I can't really tell if "everyone's" is like that, or just some are "worse" than others.

Here's an image with them visible with the screen on (and at an angle) - difficult to take a photo of - but much easier to see with the naked eye.

Went and checked out an Optimus G today (Nexus 4 isn't actually released in Japan). Given that a Nexus 4 is just a remodeled Optimus G I thought it'd be worth comparing screens. The digitizer matrix is barely visible on the G I was looking at with the screen OFF. With it on you could almost see it at some angles. It is much more visible on my Nexus 4 which you can almost always see with the screen off and at an angle and often with the screen on.
I'm leaning towards my phone being "less than a perfect example of a Nexus 4" and not the "norm" at the moment.

they are much more noticeable in Rev 11 devices and they where barely visible in Rev 10, i am sure that there is a technical reason behind it

See that explains it a little more. Not sure I see the logic in putting a screen with pretty decent viewing angles on a device and then sticking a really visible digitizer on it though.
I've contacted the seller and I guess I'll wait and see what they say in regard to it.

[Q] Image Retention

Hi i have the phone about 10 days, and noticed some image retention in grey background, the most in the nav bar keys.
I run this test
http://www.marco.org/rmbp-irtest.html
For 5 minutes with max bright and when i change to grey i noticed the image retention.
Any more have this problem or i need to change my cellphone ?

Any can test this please ?

It's the nature of the beast. Our LCD displays are immune to burn in caused by phosphor wear, but they are susceptible to image retention.
This applies to LCD televisions as well. AMOLED screens on the other hand (think Samsung) can suffer (and do) from phosphor wear leaving a permanent ghosted image behind. Luckily for us we can usually get rid of any image retention issues by turning the display off and leaving it off for 24-48 hours.
I have heard of extremely rare cases where the image was reportedly "retained" permanently but I've never witnessed this first hand.

So, this is normal ??? I dont see the image retention in normal use. Only if i put a grey background i can see the softkeys, but if i play a game or see a movie i see nothing.
Or i have a defective screen and i need to change in the warranty ???
Thank you !

I wouldn't consider it normal if it happens often with normal usage, but it's a common temporary issue for PLASMA and LCD displays/tvs.
For example, you could get the CNN crap at the bottom temporarily impregnated onto the TV display.
Now if the images doesn't fade away after the screen has been off for a while then no I wouldn't consider that normal.

Sounds like harmless transient image persistence. If I leave my display on the page you linked for a good amount of time the same happens to me.

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.

I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.

I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.

Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.

Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.

I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)

You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!
Good luck...

image retention?

So far this has been the best mobile device I have ever owned from Palm, to BlackBerry, Motorola, iPhone, Samsung, Nexus, Asus. This has also been the best OS I have used to date. No lag, no battery drain, no boot loop, and I get a removable battery.
Too many features others lack for the same price with less storage for the same money as the V20.
All that being said there is a problem with this phone that also ocurred with my V10. I keep the screen on at maximum brightness all the time since battery is not an issue with this phone (I have many spare batteries). About 7 months into my V10 I started noticing "ghosting" along the left and right edge of the screen. I use white icons which means I always have a dark wall paper. I could notice a very thin whitish smear along the edges. Its not bleed like you sometimes see on the second screen. What I notice goes away when you turn off the screen a while or you switch to a lighter colored background. Then I started noticing that icons for notifications were beginning to burn into the screen when using a dark background... Very odd because this is almost always an issue with OLED screens and not LCD displays like on the LG phones. Then the screen burn in started occurint on the main screen, typically when a bright image is on the screen for a long time and when switching to a screen image with a dark background the borders of the previous image are still visible on the new image. Once the phone is off for while, again, the retention issue goes away but comes back if the same image is on the screen for more more than 30 seconds or so.
Thankfully This does not affect video playback or video streaming. Its only with digital images, logos, or text.
For those not familiar with this problem its called image retention.
I placed a warranty claim on the V10 and a new phone was sent. I traded in the replacement phone immediatley for the V20. And now only 4 months into ownership the exact same problem is occurring... Grrrreat.
When I called LG about the V10 they had no idea what I was talking about. I pointed out that this issue has been discussed in the forums for the last year.
Are you also seeing this issue?

it will go away its not really screen burn in, lcd's have this issue and its common, turn screen off for 24 hours and let the lcd cool off and the ghosting will go away. The LCD's dont have the same screen burn in that the OLED screen would.. but latent images will occur if your keeping it on non stop and high brightness. IPS at its best.
also try and use the screen burn in app and let it spam the screen with the multi colors overnight, this will help cover the burn in like ghost images.

24 hours? Hmm... I will try 8 hours tops because of obligations I need to be available by phone all the time.
I have had IPS displays before that were on all the time and didnt see this issue before...and I run all my devices into the ground.
My Plasma TV has latency issues, my Samsung AMOLED displays have burn in, Samsung LCDs had vertical banding, this LG IPS display has latency...so which displays are immune from premature (in less than one 12 month) issues?

V10 , V20 , G5's displays ( maybe include G6) are quantum dot IPS so they all meet image retention . Other IPS displays never meet this problem

I noticed this issue on my v20. If the phone remains off for a bit the image goes away. It can be annoying but if it doesn't hurt the phone

The screen on the V20 isn't a regular IPS, it's a "quantum dot IPS" which may be more prone to some degree of image retention due to their form of illumination (I don't know a lot about it but it's a kind of atomic luminesence) which supposedly increases colour accuracy and range while lowering the power requirement for for the backlight.
It's possible this might be the root cause of the 'ghosting' but I'm mostly guessing.
Ironic though if QD displays are prone to ghosting, and LG knowingly equipped thier phone with an always-on second screen with that tech.

Yes. I'm on my 2nd replacement for the same issue. The phone I'm typing on is now having it. The screens last anywhere from 6 to 8 months before breaking down.

Glad to see that this isn't only happening to me, I find it super annoying, I never had this happen before on other devices, and it's an unacceptable occurrence that of course nothing will be done about it, I for one can't wait to get rid of the V20.

same thing started happening to my v20 recently, around 4-5 month old phone. it's an annoyance that should happen to a flagship phone, but it looks like we're SOL...

Tilted Pixel lines Problem.
I am also facing same problem with my 3 months old LG V20 Phone.
My phone have one more Problem.
I can see pixel lining (in whole screen) even though it is quad hd display. But the problem is that it is not horizontal, It is tilted 10 degree, and there is no vertical lines that I can recognize . And it is annoying to me.
If the screen is equally pixelated then I should have seen both vertical and horizontal lines of pixel equally like you can see in TV LCD Displays.

I encourage anyone whose 12 month warranty is about to expire to file a claim. And not use the phone at maximum brightness unless outdoors. Luckily I had some other issues with the phone like NFC and the speaker being somewhat distorted and the phone was replaced for those issues as well. If you see any deterioration in any other hardware aspect of your V20 you should definitely file a warranty claim.
I plan to keep this warranty replacement for another year as the only phone with the image quality I like is the Sony Experia XZ Premium which doesn't work with Verizon. Believe it or not I compared the V20 to virtually every new OLED flagship anr they all had a dingy yellowy color compared to the V20, including the new iPhone X. The Sony was the only phone that had both the color accuracy like and LCD but the deep color pop of an OLED. Best of both worlds with the only 4K screen and battery life better than my V20

It is my understanding that the V20 will get image retention, but not actually burn-in. Is this true?
Also, I have searched for solutions to the image retention problem. Most solutions advise the use of apps that cycle through colors or simply leaving the device off for awhile. I used a color cycle app, which helped, but the issue returns. And leaving my device off is, simply put, not an option. I did come across a post about replacing the thermal paste. Any truth to this method?
But I'm wondering, if I go through with taking my phone apart to apply paste, wouldn't it be beneficial to also replace the screen as well? Or am I missing some factor I haven't read about yet?

Once image retention sets in it will return once the screen is on for long enough. I ran those screen burn in apps overnight for months. Made no difference at all. The only option is to completely replace the display if you can get it cheap.

No need to do all that, install Night Screen by paper airplane dev team and set the slider at around 80%(make sure you're on the moon icon). Also let the screen cool off before you do this and set it up. You won't really notice the filter much and all the retention problems will be a thing of the pass.

@porscheoscar - No kidding lol Replacement LCD are not cheap. I'm gonna keep an eye on them cause I want to keep my V20 as long as possible. One of the last phones, that I'm aware of, I can carry an extra battery for. I love switching batteries while my friends with their latest, greatest phones watch their battery percentage like a hawk hehe
@salvichulo - Thanks for the tip ^_^ I installed it & am giving it a workout. I try not to be on my phone a lot, but I'm a gamer ;P Once phones became powerful enough to really game on, I killed my Xbox Live account & game exclusively on my phone. When I get the money I'm gonna look into getting an Android Emulator for my laptop.

A bunch of people are on here saying that they notice this ghosting problem after a few months, and that after that their phone's screen deteriorates rapidly. I just got this phone for Christmas, and I love it, but I noticed this annoying ghosting problem immediately. Should I be worried? I'm a little nervous it's getting worse.

why don't you root your phone? By rooting your phone you can change color setting by using custom kernel it help you with this problem .

I don't really know how to root my phone, it seems complicated, and wouldn't it void the warranty?

You can use app Nightly from Play Store, set to 75% and ghosting effect disappear
