SGS and burn-in?

Does the SGS screen suffer from burn-in? And if so, is it permanent?

Yes and yes. Its most likely to happen to the status bar since it is almost always displayed. You can help prevent it by using a launcher that allows you to hide the status bar.
http://en.wikipedia.org/wiki/Screen_burn-in#Plasma_.26_LCD_.26_OLED

wow thnx for the heads up on this garbage! this peeves me, it betta come with warnings like plasma tvs

The problem really isn't that bad.
Tilting the device sideways sometimes to move the status bar around is plenty to prevent burn in of the status bar.

I've been using a Cowon S9 (AMOLED) everyday since Feb '09 that has static images displayed on it a lot when playing music, and it has absolutely no signs of burn-in.

I've always been under the impression that only CRT can suffer permanent burn-in. On LCD/LED you can get residual image sometimes but it will not be permanent.

I thought the answer to this question would get yes and no answers just like every other SGS issue gets a batch of yes and no's here.
So these dang screens suffer the same as plasma screens of yesterday?! Having to use the SGS differently than other types of devices sounds like another real letdown. The iPhone doesn't have much of a status bar and it's annoying compared to the pulldown status bar of the Evo/Android. In other words, am I the only one who thinks it's no good to have to hide the status bar or any other feature that would be fine on other devices? Not asking for perfection but the SGS does some things better than other devices. It would be nice if it also did all of the other basic things all the other superphones can do like have a status bar always on (without causing damage to the display) because....well......it's a status bar.

There really is no evidence that OLED has burn-in issues and with so many OLED devices out now I've not heard of one instance of it; even the wikipedia article posted here doesn't cite it's sources.

I first thought of this after watching a pocketnow.com video in which they said it has happened and that one could just hide the status bar to help prevent this from happening. I don't know why this bothers me, due to the fact that I seem to get knew phones often. Regardless! I would be none too happy if after just a few months I too end up seeing a shadow of the status bar showing up during the boot screens. I'll try to locate that pocket now video.......

The siaplay uses a pentile matrix to reduce the powwibility of burn in. Samsung has already considered this and found ways around it, you dint need to treat the phone any differently.

Well that sounds good to me, let's hope it works out that way.

There's no chance of getting screen burn on a modern mobile phone display, I really don't know why people start rumours like this?
Screen burn is only ever likely to occur on a crt, plasma display or really old lcds. A modern lcd / tft or oled will have no such problems. Even if there was, it would hardly be unique to the sgs...

Again this is what they said about the Nexus One. They say they could see the status bar ghost/shadow on the boot screen. I've done a little research now and I do not see any clear answer to this as some say as you do and others say it does happen.

That would be contradictory to the way an AMOLED screen works. The term 'burn-in' is actually incorrect for AMOLED screens and is unrelated to the effect seen on plasmas. The problem with AMOLED is the organic nature of the dyes used to create the colours as they fade over time. The blue channel is the worst, but with the latest version they have a life-span of 10-20 years during which they degrade down to about 60-70% of their original intensity.
That's much longer than the typical lifespan of the phone.
Now with a Super AMOLED screen, if the pixel isnt coloured, it isnt lit and powered. So if it has faded and its not enabled, you cant see that its faded. If it is enabled but faded, you'd be very hard pressed to even notice it, because its still showing the right colour.
What you might see after several years of having the screen on all the time is some yellow-ing around the battery and 3G icons on a pure white screen. But thats several years with the screen on in excess of 12 hours a day, with the status bar showing. But I think it's pretty much common sense not to do that.
Oh course, we rely on the technology manufacturers to be honest about their lifespan claims, so only time will tell for sure.

The pentile matrix fixes this issue, if I understand it correctly.

It doesn't stop the dyes from degrading over time, but it might soften the edges of any fading making them less noticeable. Unless there's some other technology associated with the pentile matrix I'm not aware of. ( I design graphics chips, not displays, so I'm just guessing )

I thought I had a "burn in" problem with my 24" iMac but it turns out it's kind of normal, but reversable. It's something to do with exercising the screen elements, and burn-in is more likely to occur on a young screen with least exercised elements. As the screen ages the elements equalise (same amount of exercise on average) and burn-in is less likely, less noticable, and entirely reversable by powering the screen off for a length of time (my iMac's "burn-in" would disappear after being powered down overnight - before which I had not powered it off for weeks).
Anyway, I could be talking out of my proverbial, but that's how I understand it with modern screens.

miker71, your iMac's LCD screen is a very different technology from the OLED screens on the Galaxy S.

It does, actually. The whole reason why they use pentile is so they can extend the life of the blue pixels. We have seen that t has some negative effect on readability, so obviously the main concern has to be lifetime.
So how about some red colored status bar icons? Is that too hard to do? Not only does it protect the blue pixels, it also reduces power consumption.

lol yea i remember reading that about the red. still these posts have assuaged my fears a bit.

Light bleed !!

Im very picky so first I notice a tiny chip in the surrounding metal and I can feel it by hand, but I thought oh well this is ok if the screen is perfect. but then when I turned the brightness to max, I noticed light bleed at the upper corner. It's also noticeable at 50%. RMA asap.. shame I just got it today, the replacement could take up to 3-5 weeks. Actually I ordered this for my bro who is oversea so I need to get the replacement before the last week of january for my uncle to bring it oversea to him, and this makes me worried if it takes till february. I don't wanna send a defected one to my bro and he's really looking forward to this.

This is the extent of my light bleed (pic below).
I've decided to keep it regardless; I don't invest much time looking at a blank screen when using my phone but if your brother does, godspeed and good luck.

Turn any LCD to full brightness and you get it, the only reason you don't see it from the media is they all have auto brightness on which solely exists to hide this IMO..
If it bothers you then use OLED.
The so called amazing Retina screens Apple have used have the same issue when you turn it up full brightness....

Wao... actually mine is better than this (only 1 at the top right corner). But consider this is a phone ..light bleed is not acceptable whatsoever. On a tablet it might be ok. I can keep this N4 till I het the replacement. Hopefully the replacement will be better.

You might be right... I have a S3 and there's zero light bleed on every unit ive seen (3 total) since its amoled. Ive never owned a lcd phone so I dont know. But if this is a common issue for lcd screen then im ok with that. I just dont wanna buy a defected one.

Auto brightness exists to save battery and increase brightness only when necessary, not hide light bleed

I find auto brightness to be perfectly acceptable on my nexus 4 (way better than gnex) and notice no light bleed . only time I notice it is on the boot screen

I have similar light bleed on my screen but I never have my phone on full brightness and at auto I notice no light bleed so I am content with that. No other issues with the phone so will not be RMA it just incase I get a phone back with other problems.

lol.. will lg ever learn? this happened on the g2x (but worse).

I have a little on the top right of my screen. I do notice it, especially since I'm coming from an AMOLED screen. This phone is easy better, and I don't want to RMA it and chance getting one with a big problem. But my Nexus 7 uses an LCD a well, and there is absolutely no light bleed. My HTC ReZound had no light bleed, and neither did my LG Spectrum... both of which use 720p LCD panels, though slightly smaller ones. So, I'm a little frustrated. But, it's still the best phone I've ever used

any amoled cannot have light bleeding because the technology works differently.
LCD screens have a light behind a liquid display the display cannot emit light and requires an alternative light source to be behind it to shine through so think of it as a sandwich (backlight) / LCD / (glass)
ideally there should be material that prevents most of the light from escaping around the LCD itself however its not a 100% seal hence you get light on the edges; small devices like phones its more noticeable cause the light does not need to travel as far making the issue seem worse. generally this is a normal part of LCD technology however if it is EXTREME you should RMA some light bleeding is normal extreme light bleed is not.
AMOLED Does not have a back light so there is no external light source that can leak out around the screen itself instead the individual pixels emit the light hence AMOLED will never have light bleeding.
so if you have a little light bleed dont RMA you might get something worse and yours is most likely fine; your just complaining about a normal and acceptable flaw in LCD tech.

I've owned 3 different n4's and they all had light bleed. Noticed all had them in the right top corner, with one unit having more bleed at the bottom left. Don't rma it unless it's pretty bad

Nexus4: Bright Pixels

Hey guys,
I already mentioned this in the German thread, however it may concern a couple of more people.
I just received my replacement. The reason I ordered one was I got 2-3 tiny little bright spots close to the top right corner on the display. Exactly they are located on the opposite side of the back camera. These pixels are brighter than all others. Though the spots are very tiny you can notice them e.g. if I look closely at the Google search bar on your home screen. It's not that they are disturbing me but I feel on a new device there should not be such issues. You never know how far this is going to get.
So, the today's device is made in Jan 2013 and it has the same spots. I want to ask if anyone of you has the same issue. Just download a pixel test app ( e.g. Dead Pixel Test by Ossibus Software) and look at that area at different angles and colors. I attached a picture to get a better feeling of what I mean.

Sometimes it is better not to go looking for these tiny flaws as often we find them.
LCD panels do have flaws, and a certain number will leave the factory with some broken pixels, some good information here http://en.wikipedia.org/wiki/Defective_pixel
Some applications claim to fix these pixels by flashing the screen with lots of colours, and they seem to work for some people, typically however the pixels are intermittently broken and would have probably just started working anyway!
Manufacturers of LCD panels let a certain amount of screens through with broken pixels simply because otherwise they would be throwing too many away and so their cost would be considerably higher.
I'm not sure if yours are broken pixels however. How are you seeing these? If you are cranking the brightness up to full and viewing a dark colour you can often see tiny pin holes of light, and this is just tiny flaws in the filters which are so thinly applied tiny breaks happen, which you wouldn't see in typical use. You'll never find a screen 100% perfect if it is this you are seeing.
What do you see if you have a dark black background and the phone on normal brightness? Pixels stuck in the "on" position would be very clearly visible. On a white background stuck "off" pixels would be clearly visible, either by showing a tiny black dot, or typically a dot of a different colour.
If you can't notice them in typical use, just don't go looking for them :good:
If they are stuck pixels you have been unlucky, and the only option is another RMA.
Regards
Phil

Had a "hot pixel" almost in the same place as yours when I got the phone is December. RMAed it and the replacement is looking good now.

This is good advice. My last 4 phones (captivate, atrix, gnex and N4) all had some kind of defect with the screen. Captivate had slight burn in, atrix and gnex had black spots that can be seen with brightness on lowest in dark room and my N4 has minor screen bleed under the camera.
Its not hard to find problems with LCDs if you look close enough but none of the defects i had could be seen with normal usage so i didnt bother to return them. There is a chance that you will get a replacement with worst defects not to mention all the hassle of having to do a rma. But then again this is xda where people freak out when they see a scratch on the screen.

Thanks, mate.
When it's black I only see light bleeding from the top. Therefore, they are not dead. I believe, during the manufacturing process a layer behind the the pixel gets damaged. I filed for another replacement. However, I don't think it'll get better.

light bleed

Are you guys experiencing light bleed from the edges of your Note 8 screen. I just got my Tmobile Note 8 yesterday.

Wow...
I was hoping to god this wasn't gonna happen again.. I hated this so much with the Note 7 -_-
It isn't bad at all when the brightness is lowered, but looks absolutely disgusting when using the phone for GPS at night.
Last thing I want is for a $1500 phone to look cheap.
Apparently this is "natural" because of the glass and how it reflects light, BUT... all they had to do was wrap the black around it to block that reflective exit alone the edges.. But they didnt.
I may just take my note 8 back over this. I couldn't stand this on my note 7
OP, you should max the brightness, show a white image, and put a credit card on top of the screen and then take a picture.

Wow! I probably would have never noticed, but I do now. Thanks! I have a VZW but it doesn't seem near as bad as yours. Luckily my case covers it so I won't OCD over it, like the bubble I have in the bottom of my screen protector, going back to geek squad tomorrow. On my s7 edge I made them change it out 3 times. :angel:

You probably aren't noticing it because it takes a relatively bright image closer to the edge for it to appear.
View a white image with maxed brightness while covering the majority of the screen, and you will literally see a white ring around the edge of the phone.
Super damn annoying -_-

If it makes you feel better, its only noticeable when the brightness is at a decent level. Plus using a case will get rid of it entirely.
I'll probably whip out the microscope and apply a fine line of black paint along the edge of the glass lol.

I wonder when they're going to get rid of light bleed. I've literally had it on every device with a screen that I've ever owned.
I thought that OLED devices weren't backlit. Blah blah blah individual pixels lit. Isn't that supposed to be a selling point of OLED screens? Where does the light bleed come from?

It happens because the glass is still thick enough to allow light to travel along the inside and exit throughout the edges.
This is such an easy fix too, which is why I don't understand why this hasn't been fixed. All they have to do is literally wrap the glass around the edges with the same material they're using the the top and sides anyway..

A blast from the past. Identical thread in the Note 7 and nearly all other forums concerning the 'edge screen design'.
It is not technically "Light bleed" That term is reserved for a phenomena (problem-fault) often common with IPS panels.
What you are seeing is......how can one write.......light escaping NOT into the screen as light bleed but light escaping from the screen.....There is a gap between the body and where the display ends, this tiny tiny tiny space, in certain situations, can indeed shine light OUT but not into the screen and there is a difference but both can be annoying IF we become OCD about it. I guess this situation is part of the edge experience? As suggested by peers, a case will stop such micro reflections or light escaping.

It sounds like you might have to go through more than one replacement to get one that doesn't do it.
Just for fun, I always follow the release of the new iPhone on Macrumors each year, and there's always a huge light bleed thread. I know (now) that this is something completely different than what happens with these phones.. People over there go through numerous replacements to try and get a perfect screen. Many never get one.
I will have my phone in a case from day one, so I guess that I won't see this.

Mine's good... no light bleed at all.

I am getting no light bleed at all. Turned my screen all the way up on a white screen and no light bleed.

at least one guy on another forum has reported his light bleed and is getting a replacement in exchange.

So maybe some were built with more of a "gap" there than others.
The way my luck with electronic devices works, I'll definitely have it. Glad that it won't be noticeable when it's in a case. I won't even look for it, because then I'll know it's there for sure and it will bug me.

Display under UV light

Before I installed UV screen protector I noticed this stripe under UV lamp. Is that normal?

I saw that too, when installing the Whitestone Dome, and have not noticed any problems.

I noticed the same thing when installing my whitestone... assuming it's normal, my display is good under normal circumstances as far as I can tell

it's basically the same shape that shown on my screen whenever the screen display dark color contrasts (but not true blacks)...that seems to resemble a burn-in.

Hi everyone, I don't think this is anything to worry about. I found the same blob on my Huawei Mate 20 Pro whilst I was trying to cure my green screen.
I then checked my partners s9 and it also had the same blob so it's definitely not screen burn.

I was told it's the loca glue used in the manufacturing process. Same thing on the Pixel 3 XL's and Note 8's. I wouldn't worry about it.

Theres almost no way it's a burn in. I have this on my brand new unit that i noticed on the 1st day of use before installing my Whitestone. At this point the screen and only been on for about 20 mins. I know this because my phone as of now only has 31 charging cycles on it.

Yup normal. However I seen a user on here who had it discolor and could be seen under normal use.
Been looking into it why I'm at work. It is an optical adhesive and perfectly normal. However from what I'm guessing Samsung let a few out with bad adhesive and that's what causesd his what he thought was burn in.
But normal to see it under uv under certain wave length's. If you see it without UV light then that is an issue. Or if you have your display on and can see the outline of it.
Same Norland adhesive we use at my work on some of our optical stuff.
Just a heads up. The light they give you with the dome is not the right wavelength for the adhesive they use. Final cure you will wanna do 2 min total for each top and bottom. If not the adhesive will still be green "not fully cured" the adhesive they use is on the cheeper end of the spectrum but fine for what it is being used for. That much adhesive in a top of the line product would be around $30. But I used it on my. Did a final cure of 2 min top and bottom. Checked it out under a high power microscope and it was fully cured. No issues with it lifting.

So you've been meaning to say that if we see this without UV light (which I see in my device when I'm in a dim room and I let my phone show dark grey to dark green colors), then it's not normal? Then if it's Samsung fault, would they fix it in a repair center (hopefully free of charge)?
Im just quite pissed off for this since I came from S9+ and I havent had any issues with the screen. Couldn't they be at least consistent with things like this given the fact the display is one of the most selling point of this phone?
p.s. and oh, just to add, what's appearing on mine is not just some rectangular flat discoloration on my screen, it has dark polkadots lined in a grid inside just like many others have been complaining about.

Before I installed UV screen protector I noticed this stripe under UV lamp. Is that normal?

note 8 had that too.

I saw the same when installing my dome glass. No issues with the display.

My 3 month old Note 9
Can see green polka dot kind of burn in during normal use. Phone is only 3 months old. I take care of my phone religiously. Just noticed a few days ago and now it's all I see.
