Screen Burn In !!!

edit: *Burn in may not be noticeable at the early stages unless you examine the screen, I used "Screen Test" app from market, please download this or something equivalent, and examine your screen closely before you vote."
So this may not apply to those who just purchased their phone, but for those of you who got your phone around launch time, examine your phone for burn in. Use "Screen Test" from the market, and go through each color, looking for burn in. Oh this is a new addition, I noticed my burn in his worse when the screen is set to the lowest brightness setting. So repeat the test after you dim your screen.
I've had my phone over 2 months, downloaded "screen test" and guess what. The AM/PM up in the notification bar has burned in!
When you download "Screen Test" app, you will notice two things about your screen. Do not be alarmed, the following is normal.
1) Very thin green vertical line along left side of screen
2)Thin gray-shady horizontal bar on top, this is not the notification bar burning in.
What is not normal....BURN IN!
Can't believe the AM/PM is burnt in after 2 months. Shame.
Samsung has to update this by having the time hop around the notification bar instead of staying stationary.
Maybe a dev can work on this?

Got mine on launch day. No burn in.

They really need to change the time and AM/PM stamp from being stationary, they need to make it hop around the notification bar, or something. This is horrible, 2 months and AM/PM is burning in!
I'm sure the signal bars, wifi, and other stuff in notification bar will start to burn in next.
I'm also worried about the battery full message that stays on all night, that will start to burn the screen too.

No burn in here. Got my phone the third week of August.

i always thought leds burned cooler so the idea of burn in never even occured to me on this phone or any other phone for that matter...i doubt a warranty calim would fix it because i think all these vibrants will eventually have burn in...it wouldnt be easy i think to have an animated notification bar, but CM6 does have an option to remove and modify stuff on the notification bar like time and signal, wifi etc.

For making me notice this, I hate you.
I don't always complain, but when I do, I #BlameWes

I have the green line on the left side and the gray bar up top, but no am/pm.
Do you guys leave the display on while it charges?
My display is only on while I use the phone, I got it around release date

Not totally for me, but I can see it faintly coming in. I have had this phone (my third one) for almost 2 months now.

I use beautiful widget works great had since day one in august screen is perfect

I'm kind of curious why an AMOLED screen would get burn-in. There's no backlight, so the only image we see is coming from emitting pixels. Is there a coating on the glass that burns in?

Good question. Could the following be a possibility?
LED's eventually start to die off. Could areas that are always lit, for example the AM/PM is always on, thus those LED's are dying, which makes that area unable to to fully brighten, giving the impression of burning in, since the surrounding LED's are still bright.
That's just a guess on my part.
Also, are you sure Amoled's don't burn in, or is that just a guess/opinion/question on your part?

I can't really vote since I've only had it for a month and a few days, but I don't have any burn in. It's probably because it never disabled orientation flip and I do watch a some kind of video on the phone daily.

Had mine since day one. No burn in. my phone barely makes it to the charger most nights and some it needs an afternoon charge so I definitely use the phone quite a bit.

Damn it. Did screen test. Area where signal bars and time would be are clearly suffering from burn in. Awesome! This, combined with the generally bad software is making me consider selling this and never buying a Samsung phone ever again. (Sad, because their TV's are the best of the bunch.) To be fair, it's only noticeable when you look for it during a white screen and only in that area. Still, really Samsung? I've had this phone for 2 and a half months.

Had my phone for about a month and a half now, ran screen test and am seeing burn in
.

Got my Vibrant the day it launched - July 15th - no burn in, I use it quite a bit, but have the screen timeout after 30 secs.

Surely is burning in. Barely see it, but it is visible.

True Black

So, I stumbled across something really cool (quite) a few minutes ago: apparently our devices really can power a few pixels selectively. In my accidental confirmation of Samsung's claim, I was able to get one of NoLED's notification icons to show on the screen without lighting up the rest of the black area for literally a split second.
Here's how:
1. You will need the app "NoLED" in order to continue. In the NoLED settings, make sure you have the icon for sms activated as well as the proximity sensor. My sms icon is set to a lime green, but I doubt that will affect this "test."
2. Send yourself a text message either from your own phone or from some other sms capable device. If sending it to yourself from your own phone, quickly lock the device using the power button after pushing send.
3. Allow NoLED to start flashing around the icon for sms. Wait roughly 5 seconds for the proximity sensor to activate.
4. For steps 4 and 5, it would be wise to be in a completely dark room to be able to more easily tell the difference between the true black and the lit black. With the proximity sensor now active, place your finger over it. The screen should turn off.
5. Now, upon removing your finger pay close attention to the icon that will appear. The icon will show up a couple of milliseconds before the rest of the screen activates.
6. Repeat steps 4 and 5 if needed to witness the true black.
This is proof that our SAMOLED screens can display true black.
I am not a developer so I have no idea how to act upon this find to, if possible, adjust settings in the our software to allow true black.
If you happen to know someone who is capable of modifying the kernels or ROMs for our devices to allow this behavior, then by all means have them follow the above steps to see the proof.
Though I hope this minor find can give someone the inspiration and/or start place needed to make these adjustments, I realize this is but a pebble in a world of boulders. Therefore, I remain skeptical and strongly advise others not to get your hopes up.
If anything, it is at least nice to see that Samsung wasn't just lying about the capabilities of SAMOLED screens, but also makes one wonder why they don't allow true black from the start.
Now, time to hit the hay.
Goodnight all.

It probably did at one point but since I changed kernels and boot animations trying to get rid of verizon crap that animation doesn't show up anymore, which sucks cause I actually liked that one.

When i power the device off in a dark room, at the end of the power off cycle I get a black screen that isn't black like the other black screens when the phone is on. It looks like it's glowing in the dark or some junk, and you can see a weird pattern like something smudged across the screen.
Is this the type of thing you're talking about? That our devices, when showing black, are actually working to show that black and not just "turning the pixel off" er whatever?

Yes, if I'm understanding you correctly that is what I'm talking about. That glowing, almost grey effect shouldn't need to occur in order to show black. I hope it is something that can be hacked, but I don't know.

I guess this makes me lucky to have 1 pixel stuck on blue. I can easily see the screen turn off in almost any lighting condition.

Couldn't it be that what you're seeing is some kind of residual charge left at power off or some pixels that change states at slightly different rates? I've seen it too and it seems to be a different pattern every time. Also, some of the forums regarding screen burn have talked about samoled break-in so maybe that has an impact as well. Can't factor out power supply leakage either, I guess.

It is true all of those things could be probable, but in order to prove that the pixels aren't turning off you could disable the lock and screen dimming functions with an app and display a black image. Then in low light conditions you could easily see the blacks are actually a very dark shade of grey. If the pixels were turning off the image would over time obtain deeper blacks as the residual charge runs out.
I, and many others, suspect the phones are programmed to not turn off the pixels. Only question is, why? The only thing this type of test wouldn't be able to prove or disprove is power supply leakage.

That sucks to have a stuck pixel! Have you tried having the phone replaced? I don't know for sure but a stuck pixel might fall in the manufacturer defect category, so you might be able to have the phone swapped for free?
Sent from my SCH-I500 using Tapatalk

Or you can go and download Screen Test and get to the black screen part of the test. It is so hard to notice, but blacks are ever so slightly lighter than if you were to turn the screen off, but it is really hard to catch. Either way, they trump any LCD black levels. They even make my Panny plasma look bad

Didn't know about that app but I'm sure it would work just as you say. And by the way that would be much easier to notice if you were in complete darkness. I'm completely satisfied with these amazing screens, but it would be awesome if we could obtain true black.

I HAVE tested it in darkness. It is just such a small difference most people's eyes probably couldn't even pick up on it. Blacks are pretty black on this.

It's only one and it's on the side, it does work sometimes. I use noled and it seams to come on at the exact same time as the notifications. Cover the proc sensor and it turns off.

Have you tried jscreenfix from the market? It's free and alot of feedback suggests it can work on stuck pixels.

Calm down man, was just a suggestion lol. But that's interesting, considering mine is extremely noticible in darkness even with the brightness turned all the way down. I suppose each phone would behave differently in this respect though.

Well I guess that isn't too bad, hopefully it isn't a sign of things to come. Back when I had my Storm 1, I had a red stuck pixel. It wasn't too bad either until it started spreading a few months later. That's okay though, I was one of the lucky ones who got a Storm 2 as a replacement from Verizon. If you havent, you should definitely try that app mentioned above though.

Yep I tried that app. I kind of like it now, maybe I will name it lol. I will save it for later, if I scratch the screen or something It will give me an excuse to get a new phone

[Q] Red light by the ear piece?

What is this for? I can't even figure out why it comes on exactly. It's not coming on as a notification light, not when docked with zune, seems like it only comes on sometimes when I plug in. It's around one of the sensors, and it's just bugging me that I can't figure out what it's for.

When you plug in what?

My charger, but I can't be certain. I know I've seen it light up, a red circle around the round sensor, but it's rare and random. No big deal, just curious ya' know?

Around what sensor
I haven't see any lights in my focus. Can you take a picture?

I think you are talking about the proximity sensor

yeah I believe it's the proximity sensor. It's whatever one is closest to the speaker. I can try to take a picture, I just don't know exactly what triggers it so it'll be kinda hard. It's a ring around the sensor, lights up red. I was really hoping it was a notification light, but alas, MS did not give us one.

Ha ha...too funny. We have all been lobbying for years to have LED's taken off of phones as battery drains and sure enough once somebody does, the complaints come in "Where is my red LED?"
I suppose that the only option is to make the phones with the LED's and then have a setting to turn LED notifications off. Those never seem to really work though.

now that you mention it....back in my nextel days, I sure hated that little blinking light. Especially at night in the car. hmmmmmmm...

Flash LED, Use carefully

Just experienced this weird thing so.wanted to let you guys know.
I am sure many of u will be using countless torch and heart rate monitor apps out there.
Today I was using heart rate monitor app for first time on this phone and the damn thing got so hot so quickly that out almost burned my finger tip after just 20 odd seconds.
Expecting something.might be wrong with the app, I started torch app, and same thing. It got hot.enough.to cause burn.
So just a friendly advice, dont use it for long period. Its getting too hot for my.comfort to even use it as video flash or torch for more than few seconds
Sent magically from Samsung Galaxy S 2.

tried "flashlight" and did not experienced the problems you mentioned. switched the LED on for 30secs, after that the LED wasn't even warm...

I just ran a flashlight app for a good few minutes didn't even get remotely warm. Was just as cool as it was without running the LED. So no issues (bar accidently blinding myself, christ that things bright)

Its more severe with heart rate monitor apps when your finger needs to be touching LED and camera lens.
None of the phones before this caused any discomfort using this app. But you cant keep your finger next to the LED of this phone.
Try it even with torch app, put your finger steady on the led and wait for 30 seconds.

I didn't even know LEDs could cause that much heat

OP - yes this LED heats quite well especially when you cover it with your finger to prevent heat dissipating.
Guys who claim your LEDs do not heat up - "you are doing it wrong" , all LEDs heat up, it is a physical process. Your battery heats up too when being charged or discharged rapidly. Your Amoled screen heats up too. Electronics - no current will pass through it without heating it up. How much is another question.

Exactly, this one heats up lot more when you cover it for apps like heart rate monitor compared to say DHD or Nexus S or any other phone I have used recently.
DHD will feel luke worm and stay that way regardless how long you use it.
This one gets toasty way too quickly.

You got it completely wrong, it's not a bug, it's a FEATURE. When you take the pulse of the unconscious person (surely after consulting the CPR app), the blistering heat of the phone LED will restart their heart!
2 FEATURES FOR THE PRICE OF ONE!
That's value if I ever saw it.

You got it wrong. You measure your heart rate, make sure you are still healthy, and then light up a cigarette with the LED lens.

What app is it to turn the led on ?

and there i was thinking i was the only one who couldn't handle the heat using the heart rate monitor apps, definitely gets much hotter than my desire ever did

There is many flashlight apps on the market. A light one I am using - Search Light
Also try out the Heart Rate Monitor mentioned by the OP in this thread - this is the app where you hold your finger to the camera covering the LED light.

Have you thought about sending the Dev of the heart-rate app a request for them to add a bit of functionalitly to adjust the light output of the LED ?
I suspect that the LED is a much, much higher rater Lumen output unit compared to all other phones. This provides all of us with better 'flashes' when taking photos. The heart rate monitor apps will not need all that light to just shine into the skin to detect the color changes as blood pulses through the capilaries. I bet you that the heart-rate monitor app developers never considered that they'd have an LED that bright to use. So a simple way to fix it would be to have a setting in the app that you adjust to get the LED only as bright as absolutely necessary. You then save the setting, and from then on the app only turns the LED on to that brightness. This would then stop the LED from heating up so quickly.
The only flaw in my above plan / suggestion is that I don't know if the LED brightness can be adjusted.

This is a good idea, bu I bet hard to implement. Agree on your last point. According to comments on that particular app that I linked above, the dev has problems switching ON the LED on the huge number of Androphones out there. Every phone would have a proprietary LED with its own driver, and I am guessing limited Android API directly for the LED? I am not a dev though , can't speak to this with authority.

turned on the led with flashlight app but after 2min i got bored. Im not sure if the led warmed up or my bodyheat warmed up the led but in any case it was still far far from hot.

Covering a bright light source with your fingertip generates heat? You don't say!
Come on guys, where do you think all the light energy goes to if it can't escape your finger? Conservation of energy, anyone? First law of thermodynamics?

Not getting hot when o use it either

Light energy need not always be converted to heat energy.
the blood circulation actually helps to take heat away from the hot spot.
This is first phone that can actually harm you if you do not move your finger. Human finger is not a solid passive body, so just imagine how much infra red energy this source is putting out.
The aim of this thread was to make people aware of it. Imagine what can happen if you left torch on and kept it on table facing down.
My last 2 phones DHD and Nexus S comes nowhere near this.
But gotta say that heart rate app works best on sgs2 due to this. You can actually see the light pulsating with your heart beat.
Sent magically from Samsung Galaxy S 2.

Out of curiosity downloaded the app (Instant Heart Rate - Free) and tried it.
I thought the app was some novelty crap but it really does seem to work .
Held my finger to the LED/Camera for almost 3 minutes, got slightly warm but nowhere near uncomfortable.

There is little light on my phone when I lock my screen.

How to solve it? Thanks everyone.

Settings-display-turn off notification light.

Oh, it is not always light, but a little light.

I think you need to elaborate a little bit, not really sure what you are experiencing. Do you have a camera so you can take a photo of what you are seeing?

Yeah, could you take a photo to make yourself clearer please? I can't tell if you mean a small amount of light (i.e. the backlight of the display is still on) or a physically little light (i.e. the notification LED).

But no problems in the day, the problem is happens at night, when I lock my screen, there is little light on my screen, I fell worried. I can't take a photo, because photos can't press the problem. the problem is happened when all the lights have turn off.

So are you saying that your screen stays on when you try to lock it? Do you mean that the backlight always stays on and you only notice this issue when it's all dark?
How is your battery life? If your screen stays on I'd expect your battery to not last very long...
Still confused about your particular situation though

Oooh light bleed? Mine has one visible when booting on google loading screen

Light bleed shouldn't be too much of a concern, because most of the time your screen will not be black and you will not be in complete darkness so the "problem" shouldn't be noticeable.

You are right. But it is really a problem. And thanks all the same.
