Screen Burn on Omnia 7 :/

The bottom application bar, i can vaguely see the icons on the screen, especially when the screen is white and there is also a little dark blob just above the windows button on the screen
is this a common issue? any way to fix?
update: Uploaded pics, its like this weird dark oval in the bottom of the screen!!

It would help if you could provide us with some pictures of your phone.

I think it's a common issue with SuperAMOLED. I had a screen burned with Galaxy S top bar, where the battery icon was. You just have to live with it...

took some pics but its not very obvious on camera - guess i'll just live with it didnt realise it was a problem with super amoled screens tho!

I would return the phone to get a warranty-replacement.
Never heard of screen burn with AMOLED-screens before. I have my Omnia7 since November and there isn't the slightest hint of a screen-burn yet.

Go to Samsung Galaxy S i-9000 area and Search "Screen burn". Theres plenty of threads and posts about screen burn. Also Wikipedia confirms OLED displays burn in: http://en.wikipedia.org/wiki/Screen_burn-in#Plasma_.26_LCD_.26_OLED
You can always try to replace it, but doubt it they will...

Oh...I just knew that blue colour will fade with time, not that it can burn in. But this happens when something like a logo is displayed for hours every day. I doubt that this effect is meant to happen with a phone display that is off most of the time and when it's switched on it displays a lot of different pictures and apps.
Hmm...I would definitely try to get a replacement -I won't accept a burned in screen.

Blimey this is like Plasma Display burn-in all over again....
Glad I have an HD7 then

Returning a phone for repair is so much hassle tho it can takes aggess and may even lose all my data on the phone (hmm unless latest update has that backup thingy) i'll leave it for now see if it gets anyworse! Other super amoled people beware!

Bought my Omnia 7 in germany and have also experienced a small form of burn in when I am surfing the web.
The 2 circles leave a burn in when I slide up the IE options bar. This fades away over time and is the same type of behaviour as on plasma TVs.
I wouldnt worry much about it if it fades away. Turn off your phone and check if the marks are still there! I am certain that they wont be!
But if they are ... get it fixed.

Hi, just a suggestion... Try to enter LCD test via samsung codes.. Search on this forum for samsung codes..

Yes, screen burn in is common with Super AMOLED screens. However, you shouldn't have a problem unless you leave your phone on (set to the highest brightness with a static image visible) for hours on end.
I've seen a large number of Galaxy S screens with imprinted icons on them, and the reason for that was because they were left on for hours.

I see you are on orange. Any warranty claim i have had with orange has resulted in a new handset being at my door the following morning. Pretty quick service.

I saw this on the Display Focus at my local AT&T. they have the demo mode going, so when it's not being payed with on top it always says Windows Phone and it got burned on.

Burn-in is actually the end results of some pixels faded more than others. So, yeah, blue color will easily have burn-in effect since it only lasts about 2000 hours.

I know that retuning the phone for repair will cause you wait for ages but there is not another way for it..So you should copy your private data in your laptop or any other storage device .So it will be kept safe with you...

Well i had the worst combination then because i had the blue theme setting and i decided to keep my brightness on full! so thats what caused it then!

Exactly. On my Captivate (Android), I found most of the wall papers on Android are blue themed. In early days of Nexus One, it was reported that using a red theme not only saves your blue pixels but also saves battery.
In comparison (2,000 hrs of Blue pixel life), modern plasma TVs typically has 80,000 to 100,000 hours of phospher life. So, AMOLED/OLED screen is way to easy to get burn in. The only saving grace is most ppl already move on to new phones well before all these panel life span issues show up.

I've uploaded some pics! One is not much use, i was amazed how microscopic my cheap webcam was!!!! but still it woulds seem the dark patch is growing and hmm i didnt know that about the blue pixels! wont be using that again!

AMOLED and Themes - important note

Important to all theme developers and users to read before making/downloading themes.
http://www.scribd.com/doc/42669045/4D-AMOLED-Presentation
Green is the best at 40K hours, Red is 25K and Blue is 12K hours = Conclusion that green themes is best of the best for AMOLED like Jumba's NeonGT was. Someone should save Jumbas theme who has skills to rebuild neonGT because it was almost complete green and very easy to eyes.

Nice info
It would be really useful for Theme developers/moders
Sent from my JVH_DeOdex~®Voodoo--I9000 using Tapa

Ok, the blue pixels have"only" 12k hours until the brightness will decrease to a certain value. Did you even took the time to calculate what 12k hours means for a phone with an average of 4 hours of screen on per day? ... The answer is .... about 10 years. I wonder how many amoled displays from today will still exists then.
Later edit: not to mention that the respective document is from 2008.

i'd say black is even better

Jossilint is right. I had a samsung wave before i bought galaxy s. Most icons were blue and white in top bar. After a couple of months you could see the shape of the icons in fullscreen mode, especially on blue or grey backgrounds.
So you can notice when blue led's are getting older.

AMOLEDs have improved a lot since that article was posted. Infact, the rated lifetime of the AMOLED pixels actually indicates the time after which the intensity of the light emitted will be degraded, but not totally gone dead. We know that Blue degrades faster, so if you happen to see the screen showing more of Green and Red and comparatively lesser blue, it would be a good time to get your screen replaced.
And coming to my personal preference, If I manage to use my phone for around 2 years or more and start seeing these issues, I would definitely pay for a new screen. Just because I love the screen..

i think most people will never notice decreased brightness of blue oleds. only in top bar, when you use the same blue or white icons at same position over months. even then it is only slightly visible, but it is.
i'm not the only one reporting it. i've seen a couple of wave users in forums with similar effects. and wave is using exactly the same display, only size is smaller.

Nice info !
Thanks for sharing

Yes but not with greywhite text (rgb all in use) but with green or red green mixed. I have readed lot of xda SGS burn in horror stories even after couple month(i assume max brightness used) and i am sure that this degraded light was blue.

I think you guys are overreacting. You'll end by NOT using your phone because you will always look not to burn the display. You'll NOT enjoy the beautiful colors and teh extraordinary contrast because of the same reason.
WTF? ... we are talking about a device that was built to entertain us, not to spend neurons in figuring out how not to do things with it.
Just my 2 cents.

You can enjoy, just change habits a bit like not giving max brightness in sun(just use better angle and medium is ok). SGS is not meant for hours of navigation in car this will kill most fastest, use TomTom or some other lcd based phone, SGS is good for quick navigation. SGS is perfect for darkness because AMOLED has no light leak like lcd and has best colors.

SGS is good to be used with whatever application you want and in any way you want. To change habits because I have an AMOLED display will mean to change habits because of a device instead of changing a device because of my habits.
Is like the old saying: "are you living to eat or are you eating to live?" Everything is a matter of perspective.
I consider myself more important than a device ... so I'll use that device to my satisfaction, not the other way around.
So please ... use the SGS to enjoy what you're doing. When the SGS will die (no matter if is the screen, the battery or whatever) you can always get a new one .

[Q] Would this qualify as defective?

My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.

unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that

All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.

Yellowish tint on screen?

Might be being paranoid due to 2 XL screen issues but has anyone notice a yellowish tint to the screen? It almost seems like off axis is more pure white and looking directly on is a warmer white if that makes sense. Might try to take pics but not sure I can capture it.

I haven't noticed any hardware problems with the display yet, although I do have black clipping in movies.

Instead of starting a new thread I decided to post my issue here because it's screen related. I don't have any yellow hue with my screen. I unfortunately have a pinkish hue on the right side of my phone. I saw it immediately after powering up for the first time. Kinda reminds me of the S8+ fiasco. It's just in the right side and starts about the middle of the screen and heads up to the top. I called Google and they took my issue very seriously. They wanted pictures and it's a very hard thing to capture with a video or pic but they said they could see it in one of the pics I sent. They have me play some white screen YouTube video and wanted a picture while that was playing. Anyways, they took my info about the issue to some higher ups and called me back about an hour and a half later. The person I dealt with was nice but a bit pushy with getting pic results. He was concerned about some widespread issue because the phone was just released. So he said that these panels have some color shifting (ok? Already went over that) but offered to send out a new replacement. That is me basically buying another and not getting charged unless my original phone isn't returned on time. I'm very disappointed with the screen having this issue. I went through the whole blue screen last year. I had to get two replacements until I received a "good one." Anyone else having screen issues with color?
Sorry to hear about your yellowish screen issue. If you aren't happy with it I'd return it. There are a few friends of mine that have great screens

Here is what I'm noticing. Maybe that's just the way it is and it's something I've never noticed before. The funny thing is I have a Xs Max and the Pixel looks better. Interestingly enough the second picture (pure white) looks similar to the Xs max if true tone is turned off.

My display is great. Beautiful. I'm grateful too because I went through 7 2 XL's before I found one with a display I could deal with.

Adaptive brightness, if on, will turn the screen yellowish in low light conditions.
Otherwise, I didn't notice anything since I received the phone today. I've been using it all day.

Nope, mine has been fantastic. Looks great.

Going to have to go check other devices in store. Can't tell if what I'm seeing is normal without another unit to compare.

No matter what phone you get an OLED screen is a lottery to how even the whites are or the degree of hues

+1 I've seen some "comparisons" saying the 3 was warmer than the 3XL they saw. I'm opposite here. Received a 3 before launch day. Nice, cool screen (which is my preference). Phone felt way too small for me so I picked up a 3XL at Best Buy yesterday. Quite a bit warmer than the 3. Returning that one today haha.

Haha If it's noticeable straight away and takes away the enjoyment of the screen then a swap is the best way. I've had devices from Samsung, Huawei, OnePlus, Google etc and I've had bad tints or uneven whites on them all..so part of the oled game

Question [CLOSED] Poco f3 green tint issue

Hello iam a new member on XDA,
I want to ask a question, can the green tint on the Poco F3 be minimized with just a software update?
and this green tint occurs when activating the screen in dark mode, 120hz, brightness is below 30%, in low light condission and occurs when displaying dark gray, will this get worse for long use or not?
I was worried because it was my first time buying a smartphone with an amoled screen
Thank you.

Someone tried hentai os and reported that there was no green tint in that rom, so it is probably a software issue. Lets hope it gets fixed in future updates.

Yeah lets hope its gets fixed in futurs update, thanks for your answer.

I'm still waiting on delivery for my phone, cannot comment on the issue right now.
However, I think a future software update can minimzie the effects of the issue.
I'm not sure if it can eliminate the issue altogether since it seems to be a prominent issue with all OLED panels.

Thats called (not uniform issue). It cant be fixed by software update. No matter what you do. Similar to Oneplus 7t/8t/8pro as well.

Don't think I'll ever use the brightness that low, but I'll check my unit once it arrives.
I was contemplating on getting the Blue color which I think is a newer batch, but I pulled the trigger on the Black on as soon as the seller on AliExpress allowed shipping to Canada (didn't want to wait to take a chance and have to wait longer).

Sorry to say this but this is a difect inherent to the production of amoled screens.
i had 2 poco f3, the first( wich had also this difect) and a second one that i'm using right now that does have a perfect screen.
Having a good display is just luck, returning it might not solve the problem ( they can send you another one with a "bad screen") and the green tint is not eligible for repair
Software can't do miracles either beacause they can't calibrate a screen solely in the area of the problem and if they reduce the overall "green" of the display they make your screen purple on the "good side".
Also different displays are affected to different degrees so they can't release an update that is good for everyone

Unfortunately, but it's true. Manifacturers doesn't see a partial green tint of the screen while displaying grey colours at low brightness levels as a defect.
Oneplus and Pixel Phones are also plagued by the same problem. you have to win the screen lottery to catch a good one

My K20 pro is oled screen and there is zero green tint in low brightness so it is not all oled screens. I think it shows more obviously on grey backgrounds so i will see if i use substratum black theme on apps when i get my phone that is if it fixes the issue.

you are right... its really obvious more when i have a OP7PRO next to it, the oneplus screen is perfectly uniform.
I will try take a photo with one next to each other.
This is the Poco F3 8 256gb Arctic White

Double post... idk why but xda gave me error.

I don't expect that. Do you really think that a software causing this?
Lower grade LED panel is the cause. Nothing new.
They can only try to "hide" the problem with some color profile management tweaks.

nop i don't think so, its sometimes less noticable depending on your screen colour settings but is always there .
During the day is hard to notice so is not that bad i guess?
But during night , man its impossible to don't see it .
Mine is like way too red on the sides and green in the middle.

I dont have strong background in electronics but this is my personal opinion. Please correct my terminologies.
I think, the quality of the Amoled display of Poco F3 is just too high. It looks like you are watching 144p video in a TV with 4k display to the fact that you can literally see the pixels. I think this is what happening here in Poco F3. The quality of UI esp. the grey is too low for the Amoled display.
What do you think?
