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!

Huawei Screen Red Tint Issue

Several /r/hwatch users are reporting a red tint on the screen even when it's supposed to be off (completely black pixels). Support tickets have been open but unfortunately there's no line to actually reach Huawei for support, only 3rd party call center (Knoah).
Are any of you experiencing this? Currently it seems to affect ALL Huawei Watches. See below for details.
http://www.reddit.com/r/hwatch/comments/3mcsdf/_/

Yup, did the test with a black watch face I did on Pujie, and I could indeed see a red cast when I went in a dark room. What would be the impact of this? It doesn't seem noticable except when you put on a completely black screen. When the watch face times out.. then it is completely black....

1. Ambient mode drains more battery than it should.
2. Risk of red pixel burn-in.
3. All images and watch faces are slightly more reddish than they are supposed to be causing it to look bad.
4. Dim faces on black backgrounds will have much lower contrast than they should making it difficult to read (like Wear Charge Widget)
5. For many, the Watch is their first Huawei device and first exposure to Huawei support which so far is proving to be pretty terrible. They have a 3rd party call center in the US (Knoah in Vegas) and no way to contact a Huawei employee directly to report the issue or understand what is causing it (is it hardware or software). What/if there is a fix. They have suggested swapping out the watch but so far all watches seem to be affected.

I bet most don't notice it. I knew something wasn't quite right as soon as I turned it on. I might not have noticed it if I didn't have an urbane.

Same. I knew something wasn't right when I turned it on. Hangout contact images looked terribly over saturated and unnatural. And even in ambient mode, I could tell blacks weren't black like an OLED should be, putting out more light in a dark room watching TV. Huawei said it was only affecting a few devices and they'd swap it out but never did. So I bought another one overnight from Amazon and same issue.
Trying to raise awareness so Huawei will take it seriously because right now I think they are shrugging it off since they are the best reviewed smart watch.

Color saturation & accuracy

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the Honor 8's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!

Accurate? Nop. The display is way to cold by default. Even on the warm mode I can see a bit bluish. The display need some tweaking. Get it right honor!asap!

well saturated display, wish it was amoled

I haven't received mine yet, but the Anandtech review highlights the display as one of the weakest areas:
CCT: 8919K (should be 6500K, far too blue)
Average ΔE2000 greyscale: 8.82 (this is colour accuracy, and lower is better - this is one of the worst of any phone)
The red and green points are wide gamut, but the blue is short of sRGB.
They have more numbers, but needless to say the LCD panel is extremely poorly calibrated, and they claim that none of the colour calibration settings make anything better. I'm hoping in real life, it isn't as bothersome as in theory.
Can anyone who has theirs comment as to these specific concerns, because they're what's worrying me most...

It's rubbish really. Good contrast but nothing about it is correct.
*Gamma ranges from 1.2 in the midtones to 1.8 in the shadows, and just today I noticed it gets even worse if the ambient light sensor detects very bright conditions (gamma is made even worse to increase midtone brightness).
*Black level is 7 or 8 RGB levels too low.
*Color temperature is very blue and the color temperature setting provided does almost nothing, the range is too small.
No way to correct any of the above. Photographers and graphic artists should stay away from this phone.

This has me concerned, I was seeing the Honor 8 as my move back to Android (on an iPhone SE now bought in anger at the Nexus 5X's unbearable slowness), but it may not be. I couldn't resist $260... I won't actually get it until just before Christmas as I'm not in the US, it's being shipped to a friend.
Are there any third party tools that could fix this, or any hope of better calibration coming in EMUI 5? It seems like the LCD should be good, and it is a purely software issue...

Waiting to receive mine so I can rate in all of this threads.

I really like this phone. Is there any way to recalibrate the screen?

32 vs 64GB
Colors seems to be dependent on what device u have. Or maybe on what type of display is build in.
Actually i own two Honor 8, first one in blue with 32GB (since September) and the Premium version with 64GB in gold.
The 32 GB has a dark screen with blueish tint while the 64GB Premium version is the one that deserves his name. Rich colors with a nice touch of almost good balance in saturation. Should not be but it is so.

thats weired, so they are giving different lcd panels for different storage models??

I haven't heard anyone else mention it, so it could be a one off? I have heard of lines of phones shipping with the screens all calibrated (or not calibrated I guess) so that some ship with definite shifts in color so some units arrive with yellow, blue, pink, or green tinges to the screen.
In any case I would like it if Huawei had an sRGB mode option available.

This would be hard to provide given it doesn't sound like any calibration has taken place (given the reports of different panels). Reminds me of the Nexus 5... had three different Nexus 5s with different colour balance - one VERY different (warm and almost incandescent like, vs the very cool of the other two - one greenish and one purpleish).
You can't take a phone that hasn't been calibrated and go back and offer calibration... the screens need calibrated before they leave the factory, then you can offer calibrated modes. The best Huawei could offer us, really, is a gamut restriction (since the gamut is more or less a known) and RGB adjustment sliders.
They should offer at least the latter...

Agree

Here´s a (quick) comparison of my both Honor 8 (Gold = 64GB / Blue = 32GB).
Both set to Auto Brightness and both with same color temp.

Display Ghosting

I am noticing quite a bit of ghosting on the display. Especially white text on dark background smears all over the place during fast scrolling. Black text on white turns grey in a similar situation. The blurbusters ufo test ( https://www.testufo.com/ ) looks really bad compared to a 120 Hz amoled. Is this how the display was supposed to be?

When you buy cheap this is what you get. Mine has a red tint all over the screen at low brightness ... Very annoying.

Fortunately, I have no such issues. The screen is perfectly white on any brightness.

Same, my screen also looks good. Xiaomi is not OnePlus. Just send the phone in under warranty.

Just got my Mi 10T Pro and there IS screen ghosting
WTF xiaomi isn't this flagship phone???
Changing refresh rate to 90Hz is little better but still my eyes are bleeding
Except screen ghosting this phone is amazing
Hope they somehow update display firmware for faster GTG response

when scrolling on text it seems as if the text blurs and greys out until you stop and then it becomes the normal black again. It's really annoying when trying to scroll and read at any sort of speed. Anyone else had this issue /fixed it? I've tried pretty much every setting now and nothing really seems to help..

Obviously none of the reviewers mention this, but the amount of ghosting is disgusting. The 144 Hz is just there for marketing, and is pointless with the amount of ghosting this panel has.

My Mi 10t pro is perfectly fine, i am not experiencing any ghosting. Mine is EEA model

I had a OnePlus 8T and sent it back because of green tint. I regret doing that... It is a much better phone that the Mi 10T Pro in my opinion. Way faster/smoother and the 120 Hz oled display is far better than this 144 Hz IPS. If only it had a better camera it would be perfect. Not saying that the Mi 10T Pro is a bad phone, but the OnePlus was just a joy to use, whereas this feels clunky at times.

Well, I can do a slow-motion video, but taking pictures is the pretty much only accurate way to show ghosting I think. What else can you do to show ghosting?
Of course, taking pictures with a better camera will bee.. well better
I don't mind this type of ghosting, it's minimal in my opinion.

I'm not sure what else could be done... Slow motion would probably be better, but there is no need for it.
Honestly, I don't mind it either, it is just a minor annoyance in apps with white text on gray background.

Question edge bleeding at low brightness

Hello, tonight i was configuring my youtube app and i noticed very bad colors at the edge of the display, when the background is grey. I was in a complete dark room, the problem is most noticable when brightness is about 15%. And no, its not only the app. The bad colors are visible at a brightness from 0% to 50%.
Do you guys also have this problem?

The Mi 8 has it also, that is screen uniformity. It is hardware and it seems very common the last few years. I don't have it on my Oneplus 7 pro but it is also present on the Oneplus 8, Xiaomi Mi 9 etc.
Some folks say it is normal on oled but it isn't.
Why are the no problems with oled on Oneplus 7 pro, Samsung s10+?

I have same in low brightness don't worry.

so your unit doesnt have this issue?

i have the same problem,always visible when you have a dark(not black) background,note i had before 1 samsung s2,s4,a5 (the a5 when i was watching a movie in dark scene i could see a yellow brightness in one corner,it was awfull)and a tablet from the same manufacturer and all had the same probleme but at different level,my last Mi9t was parfect and screen didnt show that but my new F3 has it ,one side is clearer than the other one

As far as I know it is because of the AMOLED manufacturing tolerances, it seems to be really hard to get a perfect uniform display.
It shows at low brightness with grey screen especially.
Discussion also happend with the Mi 8 here:

Lol, I was just about to start a topic about this when I saw yours. Only dark gray backgrounds and top left is brighter then bottom right. Disappears at about 25% brightness. On the photo it seems green but not to the eye...
So if I send the phone back I'll most likely receive a new one with the same issue?

you have a chance to get another F3 with same issue or less visible or worse

Lol, as u can see, my issue is in the same area, but mirrored.
I think, if u send the phone back, maybe u will get one with the same issue on diffrent corners. Only if u r lucky, u will get a good screen but then maybe the vibration motor starts crackling xD
I will keep my phone, cuz everything is fine for now

Well, yes, I'm a nitpicker really and there's always a small problem with a device it seems. I can't find anything else so I guess I'll settle for a small uniformaty of the screen. After all it's only with gray and in a dark surrounding. When watching a dark scene in a movie in inperceptable and maybe I can switch more elements to black using a custom rom (hope lineageOS will show up).
And maybe when there's a way to do DC dinning and not PWM it'll be better....

It is in general really hard to get a perfect display, be it on phones or on PC monitors.
Also TN and IPS panels show their weaknesses at "grey" colors, it makes the uniformity visible to the human eye.
Additionally trails and overshoot of moving objects on a grey background are most noticeable.
Not sure why "grey" is so devastating

I don't know. I'm from NL and here we have a lot of "grey areas" so guess I'll have to get used to it

Mine has a similar grey gradient visible at low brightness and solid colors, but it doesn't seem to be discernible in anything but settings. My old phone has a "perfect" oled though, so it's definitely possible.

Solid colors seems fine, or my eyes don't perceive it...
Probably the same case as processor cores: bins. Maybe they pay less for getting screens that are not 100% uniform?
