Hello,
Never had a phone with Always on feature so I would like to ask if is a normal behavior to see for a few seconds a clock image retention from AOD when the phone is unlocked.
I have LG V30 H930 EU unlocked model.
Been using a H932 with AOD since day one and have never seen any image retention issues from it's use.
It's not very visible, you have to look very closely and perhaps also have some specific colored wallpaper. It lasts only 2-3secs and then slowly disappears. AOD needs to be on a screen for at least 30-60mins I think.

But the AOD constantly moves.
As previously stated, the AOD on the V30 is not a static image, but a dynamic image, (it rotates to several locations on the screen at a certain interval). That should preclude it from issues involving image burn-in or retention.
Having said this, there is an app on the Play Store that Samsung owners use to combat burn-in on their OLED equipped phones. I don't remember what it's called, but you should be able to do a search by topic. The other thing I would recommend is avoiding having the AOD on it's bright setting. Its a bit too much, even in bright daylight, and it does increase the chance of image retention, IMO.
Bright setting is off, but the brightness of AOD at least on my end is dynamic and depends on the light sensor. This "bright setting" to my eyes do almost nothing.
Ok nevermind, probably I'm just nitpicking... I appears to be "visible" only on a pinkish part of the wallpaper. It's one of the default.
I have (what I consider) an annoying slow, fade to black when I turn off the screen. Perhaps your "retention" is the same, slow change of state for the screen?
Maybe we can call it this way. I'm coming from LG G4 IPS screen which is changing such things instantly obviously and I don't know what is "normal" for OLEDs. As i said, clock number from AOD after unlocking has its footprint for a moment on a wallpaper, slowly disappears.
The screen is otherwise pretty good if I cosider some horrible issues reported here or on reddit.
But still apart from this "retention" issue I found 2 more, but basically small issues described here:
https://forum.xda-developers.com/showpost.php?p=75657168&postcount=670
so don't know what to do.
I'm still within 14 days return/replace period, but I'm worried about worse screen since this is still a lottery.
Not sure what is your issue. Turning off the screen is doing fine. Just one quick "animation" and everything is off.

I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?
OK, I have seen several threads here, concerning image retention problem, sometimes marked as screen burn. So I thought we could collapse into one general thread on this subject.
So, LCD screen does not have image burn problems. Image burn is name for persistent effect. What we have with our Primes is image retention. This effect is caused becouse liquid crystals in LCD gets used to its certain possition...
For example, if you have some bright background, and you leave it unchanged for about 10-15 minutes, than run some grey screen picture, you will see "ghost" of the background image in the app.
This effect can be seen in many screen technologies. S-IPS and AMOLED are widely used ones on tablets and mobile devices. They both suffer from this effect.
There is actualy big chance you won´t even notice that. Prime turns it screen off after some time, and when you use your device you are probably actually doing something, meaning you are dynamically changing the screen, so image retention has no time to take place.
In everyday use, problems could occur when you use SW keyboard for a long time, or for example game menu controls, etc.
The most important thing is, this is NOT PERSISTENT. Image retention of this type should dissapear after while, you can speed it up by either turning screen off or displaying plain white image for a while.
I believe none of our tablet displays are immune to this. In fact, even glory iPad 1&2 displays are not immune. Neither was my HTC Diamond screen. (Yes, pretty old, but it has nice VGA screen). Sometimes I get navigation cursors retained after reset, even for few minutes (on my HTC Diamond)... So I believe we just need to live with this effect. Most of the time, you won´t even notice it.
But we can share our experience. I have not notice any image retention untill today, when I needed to discharge my Prime more quickly, so I maxed brighteness (IPS+ on) and leave it in home screen on for about 15 minutes. Than I started YouTube app, and on its grey load screen, I clearly seen ghost of my homescreen background. I immediatelly retried lauchning YouTube app, but it was all gone. If curious, or if you want to replicate this, my homescreen image is the default with tree, most yellow-ish like I believe autumn sunset version

Think that is the root of your ghosting issue there, would not call that normal operation at all to leave it maxed out for 15mins. The display is super bright and I dont think even outdoors you need max IPS+ to adequately use the tab.
Well, if I am right, it sould have nothing to do with brighteness level. Like I said, it is different effect, it is not burned. But maye thrucomming light intensity has some effect on the crystal polarisation...
Thanks for the post, I get this effect with my Nexus One as well. The notification bar from having the phone in portrait mode shows itself at times in landscape.

Actually LCD panels can get screen burn, I have had two LCD HDTV s that had it. But those were first gen LCD HDTV s.
You shouldn't see anything like it on LCD screens of today. If what your saying is true then why isn't the status bar in ICS (or honeycomb) ghosting for everyone?
I've done some tests recently after finding this issue on my Galaxy Tab 7.0 Plus. It was VERY dramatic on that tab. Only a few seconds on one screen, change to a screen that is mostly gray and the image persistence was there for quite a while. And it was a strong persistence. Not just a faint image. You could easily read text and see images. The pictures in the following thread show it.
http://forum.xda-developers.com/showthread.php?t=1437445
But after having this issue, I ended up testing some other tabs I have. I've seen the issue on my Kindle Fire's (I have 3 of them). I have a Lenovo Thinkpad Tablet and have not seen the issue there. I also have a Transformer Prime and I do see it faintly on the prime, generally on the right side of the tab when holding in landscape (with power button on top). I also see it sometimes on my 30" Dell IPS monitor.
I guess the point is, it is more common than you think. But some screens may exhibit the problem more than others. That Galaxy Tab 7.0 Plus (that specific one) exhibited it far worse than anything else I've seen.
I've decided not to worry about it. If it's happening to yours and it happens very quickly and doesn't go away quickly, perhaps your display is worse than the norm. But I would expect all of these displays to show some level of image persistence. Return it if it bugs you, but accept the fact that they all may have this issue to some degree.
Thanks to the OP for this post.
There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.
Use "screen adjuster" from the market and set contrast to -60
i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..
I have this. Noticed it one night when my phone was switched off and charging.
Sent from my GT-I9100 using XDA App
I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone

Thanks for the feedback already.
@elmerendeiro: I have also noticed some 'interference' lines on my phone from time to time. I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?
Hey some days ago i downloaded an app called Dock Clock. You can check out the app here . In short, what does that app do is displaying a full screen clock and preventing the screen from going off while docked.
it looks like this...
I've also enabled a setting used to avoid possible burn in which moves the clock around the screen in small "steps" every few seconds, but i am not still quite sure if its safe in the long run to use it as a desk clock 4-5 hours a day while charging...
I am not quite informed with the burn in effect so i need your help here.. What do you believe? Will it cause burn-in problems in the long run or its me just being hyperbolic?
Τhanks in advance and sorry for any english mistakes on the post
That app hasn't caused any effects on my S1 afters months of usage. It was in horizontal position so the app couldn't really move the digits but still no issue.
And I do tend to sleep a little longer than only 5 hours
thanks for your helpfull response :good:
You should be more worried about the notification bar because the icons never move and often abuse burn in.
I have yet to see any significant burn-in on the notification bar either across all AMOLED phones I've seen to date.
It's very faint but for most people even hard to spot on an unfirm singlecolored background.
What most people mistakingly report as burn-in is what's called "lazy pixel" where, due to it not being used very often, it's slower and another luminosity than the rest of the screen. Letting the phone cycle a Dead Pixel fixer app for 30-60 minutes whenever it's noticeable will usually get rid of the problem.
I'm not saying burn-in does not exist but usually either the screen has issues or it's been very,very,very abused to be disturbing.

I see... i'll take the chance and ask you something else... 2 weeks ago i realised that on the midle of the right side of my screen there is a small area that appears green on pure white background... you can also notice it on blue-rgb and on red-rgb... the color of that area is nearly the same as green-rgb... its shape is curved like a nail and its like 2mm or 3mm long... any ideas? i read that dead pixels (although the area is by no means a single pixel) appear black on white background and everything else its not dead... can it be fixed or at least do you know how is this "symptom" called?
It's not really a dead pixel in the terms of the pixel not giving any luminescence, thats true.
However several people already reported that their phone had pixels which were incorrectly controlled (e.g. some blue pixels lighting up on red, ...)
which is usually due to a manufacturing fault which shortens the power-pin of several sub-pixels.
With such hgh pixel densities as the S3's screen has, that is to be expected but quality control should get rid of them.
I'd recommend taking a long-exposure photo if available, enhance it, print it out and go back to the seller. The photo should be sufficient in case they are unable to see it for themselves in a store-environment.
You should however first try a Dead Pixel app even if I don't believe it will fix the issue.
Hello, I own a i9100 and I have some burn-ins at the top of the screen that replicate some buttons of a browser or something, and some burn-ins at the bottom as well. I have read that leaving overnight an app that's constantly switching colours, with full brightness, could help a bit on that. I also read that leaving a blank screen (white image) on the same conditions (overnight, full brightness) would help as well. My question is, how true these both things are? I don't want to end with a bigger problem than the one I currently have. The burn-ins are most viewable at Blue, Red, and Black screen colors.(like if I put a background with one of those colors on it)
Never had any of these on my S2,but from my experience with the galaxy s plus,these tricks won't work.None will to be honest.It's permanent.This shows how immature amoled technology is.Learn to live with it or replace the screen if that bothers you much.
what a sign you got there...
Lucky you. Mine is not THAT noticeable if you're using it normally, but as soon as you open something with a plain color on it, the burn in shows itself on all its glory. So right now you can't tell if leaving the white image all the night or the thing switching colors will damage my screen more?
mwehehe
Well,back then when I tried every method you described above on my i9001,I didn't noticed any improvement nor any further damage.Even after running those for 10h+.So I assume it's safe.Can't say the same for the S2 though,have no problems with it.
