Hey!
I bought my galaxy 6 months ago. Not long after I noticed a minor issue with my AMOLED display. I could see blue "artefacts" in some bright areas of the screen from time to time. Nothing serious, just blue dots and stripes, subpixels. I even posted a picture of it on reddit (second attachment) more out of curiosity than anything but was later convinced it was probably a software issue. I did have some suspicions something might be wrong with my phone but it actually happened so rarely and the issue was so minor that I just got used to it because it didn't bother me that much.
I recently flashed dark core 2.2 along with rc6 and it got *significantly* worse. I could see blue subpixels all over the screen wherever there's bright white, generally on the lowest brightness setting. Now, I believed that the hardware got worse and it's time to ask for a replacement. So before doing so I obviously had to flash stock firmware and guess what - it all disappeared. So I flashed just the dark core again to go back to rc6 - and it was back again.
The thing is, I really love this ROM and I love the voodoo improvements that come with it. I don't think I can live without them any more. On the other hand, it might be difficult to convince people from samsung that there's actually something wrong with my phone - since it happens so rarely on stock ROM. And I think that this display defect is intensified by the screen improvements from voodoo/dark core.
My only idea is to somehow make it show up on stock ROM and send it to them just then. But is this even possible without rooting my phone? Does anyone has an idea why would these blue subpixels show up in white areas? Is it something they check with specialized equipment or do they boot the phone first to see what's wrong?
Anyway, guys if you could point me in the right direction or had any better ideas... Seriously, It would be helpful even if you said that I should just return my phone and hope for the best. I'm a student and I can't really afford to be charged for returning - what they think is - an operational phone
I attached two pictures
1. a picture of how my screen behaves after flashing the latest dark kernel
2. a picture of how my screen sometimes behave on stock kernels
I'd appreciate any help or advice
Hello all. So I LOVE my Samsung Focus S that I purchased shortly after Thanksgiving Day...all except for one problem. My phone seems to dim permanently out of no where and nothing I do will correct it back to it's normal brightness except for restarting the phone. Automatic Brightness is off and the "Auto Display Intensity" in the Extra Settings category is off. Now I don't know if this is something that specific to Windows Phone or Samsung Focus S particularly? I'm going to take a guess and say it's on the Samsung Focus S that exhibits this behavior. I also can't figure out if it's a hardware failure or a software failure. I'm beginning to think it's a specific update that is used to update your "Extra Settings". I don't know at this point. I just want to know if others have this problem.
The 2nd issue is not so much a problem now but a concern. My first Focus S had a VERY HEAVY greenish tint to it that was immediately noticeable at the lightest of viewing angles. To give you an example of how bad it was, my buddy was looking at a picture of oranges he took with his iPhone4, I thought they were lemons from the side. I went to an ATT store near me and noticed the Galaxy S II exhibited this behavior as well but the Focus S on display did not. I quickly concluded it was a defective screen as it was REALLY noticeable. My buddy gave me a call and told me he was at an ATT store across town and noticed it on another Galaxy S II as well. I made the employee take out two brand new Focus S' and chose the best looking one. They both looked identical, although the one on display had an edge over all of them. Thing is, ALL of the ones I've seen have a very slight green/blue tint to them. Is this normal with Super AMOLED Plus? Is this the Gorilla Glass Coating? I love the colors and contrast on this phone but to be honest the brightness and viewing angle leave something to be desired, more-so the viewing angle. Sorry for the long post!
I just looked at some pictures of oranges to test this. They look nice and orange do me. at an angle the entire screen starts to lose its pop. But I would not call it green more so just dimmer. Can't complain with the blacks...if only more sites background was black lol.

Would you mind doing me a favor and looking at different viewing angles on a predominantly white screen? Every phone loses it's composure a bit as the viewing angle is more and more off but I've never seen them turn a different hue. Dim a bit like you said? Yes. I looked online to see if anyone else notices this bluish/greenish tint and many do but more notice it on the AMOLED screen though a few did complain about the Super AMOLED Plus. Thank you!
interresting
Ive been running the focus s since it came out and never noticed this "tint" issue...till today. a simple image of pure white, when viewed from above is fine, but as you change the view angle so does the white begin fade into the bluish haze.
now youre all probably going to hate me but i have a titan too. when i pull the exact same image, it does not fade into blue haze. my suspicion is one of two thoughts: a) the super amoled screen samsung uses has this side effect. b) the glass samsung uses creates this effect.
personally its not a deal breaker for me as i really enjoy the clarity of images and color the samgsung has to offer. that said, the titans inability to go true black are more noticable than a slightly bluish white. but thats purely personal prefence.
FWIW, ive tested red, green, and blue matching images. the only difference i see between the two is a decreased viewing angle on the thc in all aspects. screen display differences is the likely cause.
I can see the blue/green from those angles on white screens
kinda ugly actually
still a few days left to return and get the titan....

It's good to see you have a Titan. The Titan is a pretty nice phone. Viewing angles seem quite good and the whites are SUPER bright. It's just the colors and blacks that suffer. Nice to know you can compare them though.

Hey Alright, I'm not crazy. Heh. I'm going to run to a couple of more ATT stores and see what their display units look like. My buddy just got a GSII and he says he doesn't see it, so I'm going to investigate it as well.
BTW, I spoke to someone at Samsung online and he seemed to think it was "normal" and was caused by a Super AMOLED Plus characteristic. Unfortunately I didn't believe a lick he was telling me.
I'm off to find the perfect display! Wish me luck.
i went back to the store
they want to charge me $35 to restock what I have ^^ - and cant seemed to be talked out of it....
the display Focus S had the same exact issues
as does the GSII/SkyRocket from what I could tell
the Titan's whites make the Focus S whites looks blue - but the Focus S blacks look the Titans blacks look grey
and the color palettes are so radically different - for themes the green on the Titan looks like the lime on the Focus S, and the Titan has nothing that can compare to the green on the Focus S - its ridiculous the difference in the saturation and vividness - I can see what people say about the Titan producing more realistic images - but at the end of the day for most things the Focus S is just better looking, who cares if its accurate?
i imagine using the Titan for a while you would get used to it, but side by side it looks paltry in comparison
to be honest the iPhone display looked pretty good! - just too damned small after using a 4"+ sized display - I could never use something that small after using what I have
So I went to ABT Electronics today and looked at their Focus S. It's funny, all of these places, including the Apple store choose the most PERFECT displays they can find in their inventory to show to the public, when in reality your results can vary greatly. For example, the Focus S at ABT had a whiter/bluer screen than mine in terms of whites. It wasn't a huge difference but it was noticeable. Now I want a new whiter screen. My screen seemed buttery compared to the one I saw. We'll see how successful I am. I know I may sound picky but if I'm going to keep this phone for the next 2 years, I want it to look the way I want it.
I also checked out others with the same 4.3" Super AMOLED Plus and I didn't really see much of a green tint to them. In fact one looked yellowish directly and turned whitish on the side. Weird.
OLEd is still a newer technology, compared to LCD - guess there are still some kinks to work out
Yeah, a problem with AMOLED is a slight bluish hint but I don't believe the screen is a PenTile one.
The dimming has been a bit aggressive, I just usually cover the proximity sensor with my hand and let it work again.
Has anyone noticed a flicker (then on) when you unlock the Focus S screen? Sometimes the screen instantly brings up the lock screen sometimes a second after the flicker.
Alright guys. Back to one of the original topics of the Focus S randomly dimming? I think I figured it out. My phone is over heating and the phone is dimming to try and cool it down. No error messages of overheating or anything. I noticed it today when I was playing games on my phone while charging. My phone was pretty warm. Now up until this point, my phone had not dimmed randomly for a week or so, but this morning? BOOM. Dimmed on me. So it hit me. Screen Dimming + Warm Phone = Overheating. I put the phone down on the cold floor to cool down for 10 minutes. Turn the screen back on and guess what? Original Brightness is back.
Either I exchange my phone again or return it all together. I'm in a bind because I can't get the HTC Titan for the same price I got the Focus S for (Free with No Activation).

I have not noticed this at all.
i am in the same boat
almost potentially worthwhile holding out for a Nokia set (perhaps the 900/850)
i actually think I will keep the Focus S to be honest with you
in a year or a year and a half, call up Att and see what they will work for me if I really want to - I have heard lots of success stories about calling them up and getting very discounted phones deals
after revisiting the store - the titan screen looks like **** (IMO except for the whites) compared to the Focus S - and its just too damned big - the Focus S IMO is the perfect size
and all the Android GUI overlays suck ass - so no way I get a droid - and I will certainly not pay $100 for a year old iPhone.
**this fixed mine** random dimming and tinting
Don't throw anything because I just skimmed over the thread before I am responding. I have the Focus S and had that problem. I corrected it by going to "settings>extra settings" and turning off the "Auto Display Intensity" to make it stop adjusting. Unfortunately, that setting defaults to "On" every time the device is restarted. So you have to remember to turn it off. Maybe everybody thought of this, already, and your device does this, anyway, but mine is perfect with this setting off. So, I hope this helps!

I had to use the option in the "Brightness" page under Settings. The option on the Extra Settings page applies only when it is set to a white background.
Hopefully a future update will address this and improve the auto dimming. For now, though, it's set to bright all the time.
U only need to press the power button to let the phone go to sleep, then press power button again and almost immediately the custom brightness u set will be back.

Well the dimming issue hasn't happened to me in quite a while now. I decided to keep the phone. The fact that the display wasn't perfect wasn't enough to make me want to return the phone, especially since I got it for free with no activation fee on a 2 year contract. In the meanwhile, I'm just enjoying it. Funny though, Now that I've got a 4.3" screen, I want MORE. Bring on the 4.7"!

I honestly only find it more difficult in landscape mode. Portrait mode is awesome though. I can't stop hitting the "a" button when trying to turn on caps lock. It's really annoying.

Having had 3 Samsung Amoled phones (Galaxy S2, Skyrocket, Focus S) and a SAMOLED (Galaxy Note) I will say that Samsung doesn't display true whites, it's always blueish. As far as the dimming, Go to "Settings" > Exta Settings > Use Auto Display (Turn it off, however; it seems to enable itself after changing the theme from light to dark or vice versa, as well as after a reboot.)

I believe all the phones you had, had a SAMOLED + display no? Also, I checked to see if changing the theme from light to dark turns the Auto Display feature back on and for me it does not. As for my dimming issue, it only seems to happen when the phone is plugged in and the battery is a bit warm.
Overall, I like this phone but I also don't. The display is quite delicious really. I've had it on half brightness for a few days now just to see how it looks to me and today I finally put it back to full brightness and the colors really are gorgeous. It's not perfect but I've learned to look past it I guess. Thank you for the reply.
All my screen burn in complains started with LPY ICS. Suddenly I noticed bluish color in place of status bar(top of screen) while reading web on landscape.
Later, it change to situation like on screen test status bar location seems to giving best color. Rest of the screen has yellowish tint now.
So my screen is acting weird or getting broken. Anyone else has this issue?
I want to go back to GB, but I am afraid to brick. If go back to GB, should I choose non wipe GB for mobile odin?
I have CF-Root LPY kernel.

Screen Burning?? This is kind of hard to believe, at least that ICS is causing the problem when there is a lot of people on ICS now with no problems like that. Just a defected phone probably and you should try to return it to Samsung if you have a warranty.
But, I would recommend using PC Odin to go back to GB.

It's not a defect, it's just an unfortunate side effect of AMOLED screens.
This is discussed extensively on XDA, particularly in the I9100 forum.
Your best solutions are preventative ones, use a launcher to hide the status bar, leave screen on minimum brightness, avoid leaving the screen on for excessive periods with still images and try not to leave it in direct sunlight (on or off) because this damages them too.
To be more correct, this is actually not burn in, it's the organic LEDs wearing out, the longer they are lit for the more they wear out over time and the less bright they become. Because status bar is black, they get used least and so end up brighter or tinted, and pixels used most (clock area or lock screen circles) get dimmer.

I was on fully stock LPY and I noticed almost the same thing. What appeared to be dead pixels in the shape of one blue dot and one red dot formed on my screen. Though only visible when the screen was OFF for some reason. Anyhow. I flashed back to LC1 stock odexed rom via pc odin and my screen was back to perfection. Well, if you disregard the black clipping issue

Yes, I think it is as you said. Screen colors dimmed. But, I bought this 6 months ago. It should be a defect. Your suggestions should be valid to use the phone for years without problem.

Not exactly, I remember a member of the SGS2 forum uploading photos of he's screen after using something called coyote, some sord of car navigation, after regular daily use for a couple weeks it had caused noticeable wear in his screen.
Static images are bad for these screens if you have a lot of screen on time, the most affected will be your statuary because it's almost always off (black) so it'll be brighter than the rest.

Everyday 1-2 hours I am on Google Reader and Browser with white background. But, I still think that screen should be defective to wear off in 6 months.
Currently, I use black background
I think it should be under warranty. When I am not lazy or screen gets worse, I will format my phone to original ROM. Then, go to samsung.
I got the same burn in on my Nexus. Just returned it for repair. Reading about all these problems with super amoled screens makes me wanna change for a other phone since it seems to be a common problem.
If a screen replacement doesn't fix it permanently, i hope I can get an other brand without amoled. Just not okay to have these kind of defects.
Hi fellas,
We know our SGS is old but it still is very much capable. One thing with this device that can't be worked out is the amoled burn-in. I had my SGS's screen replaced twice due to burn-in, and some of you might think that "you've had your brightness settings too high for a long time" etc. The thing is, I've been using lowest brightness setting since I had the second replacement and for over a year burn-in still take effect. I know SAMOLED is superior in terms of overall display experience but the way I use my phone isn't the same as I use it when I first had it (meaning I'm used to looking at my screen and I don't bother the contrast/deep blacks anymore as I used to). I wanted to have a peace of mind using the device for long (4) hours browsing the web or playing a game or using an app without constantly timing in my mind that the status bar or clock is now a little more burned than yesterday, something like "at this duration use, you're blue subpixel is 0.00001% weaker". Those who suffer the agony of watching a burn-in on their displays understand this. So I was thinking of replacing my screen again with the SLCD from i9003 and I wonder if someone already tried it out or if it is possible?

Hi!
did you get any answer on this topic?
I have the sam preblem, i have a Samsung i9000b (the same screen as i9000), and i can get a scren from a samsung i9003.
Have you tried making the replacement with the other screen?
Thanks! have a nice day
So my display after being replaced 2 times in 6 months started flickering. My phone is very hard to be turned on because of the green flickering.
I just want to upgrade to a S6,S7 Edge or non edge. i just want to know if they have the save problem with displays ? I want to have a phone at least 2 years, can you recommand me a phone like that ?
I was just considering switching to a iPhone even though i prefer android on phones ... o how are S6,S7s displays ? Samsung still have the same problems?
Samsung improved a lot on screen quality in S6 and after, so you should be okay

Wow that's amazing. Been using samsung s5 exynos version for the last 1yr. Never had that kind of problem till date. And it have the same display as snapdragon version. And on comparison I found that this is by far the best display out there when compared to other brands.
Maybe perhaps you might be having a faulty unit from the begining.

I have the same problem here with the display and it's not a software problem (same by original os 6 and same by cyanogenmod 14).
After the temperatures are under 10 C. i can't open my s5 with home button i must do it over the power button.
Using S5 for more than 28 months still I have not faced any issue. I just had to buy new charger apart from that not a single problem and yes I mess up with my phone so much but I still working and no display failure yet. And also I have dropped it many times, it still refuses to die.
You are just having a defective model or some internals of the phone are messed up. Because Samsh*t produces one of the best displays..

Its not a good sign. Try disabling your light sensor. Even then if you experience such a problem than it means that your flex cable that attaches the screen with the motherboard needs to be changed.

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).

The funny thing is i already did "by mistake" all the tips you said and still have this. Never dropped the phone though. This problems seems very big though, i expected a burn in to be the biggest problem, but to have flickering at a level that i cant turn on the phone. I wanted recently to switch to a Nexus 6p, but knowing that it uses Amoled too, its a bad ideea. So the only "solution" is to switch to IPS screens? (btw i want a phone that holds on for at least 3 years)
In my research thus far, the AMOLED screen technology is to blame. When the display circuits get old or damaged, they don't sustain current at low power settings. In LED screens, a back light controls brightness, but AMOLED screens send current to each pixel for brightness control. If the circuit is damaged, or any corrosion has built up inside, this could attenuate the current below the point required to sustain light flow. I see this problem with some LED and CFL lights on motion sensor switches. Just enough current goes through the motion sensor to keep it's circuits active, and that current causes a flicker in the light.
With the screen though, since the problem is only resolved when you increase the brightness just a bit above minimum, it seems anything that lowers the display power (auto brightness for example) will cause it to flicker if this setting gets too low. I also noticed that before the screen locks on timer, it dims to low power for a few seconds and flickers as a result. There are apps that attempt to resolve this by putting a translucent black screen over your desktop and apps. This keeps the power up on the pixels but adds a black overlay, kind of like a screen filter. You can adjust the darkness if you need it to save your eyes when reading in the dark but it doesn't help save power any. They also require a rooted device, which could void warranties. The reason for this I believe is because apps are supposed to operate in a way they don't intrude on each other, and a filter that lays over your screen does in fact alter the output of your display rendering. With the added security concerns of these apps possibly collecting screen shots and sending them to another site, I would avoid this. Best to use a physical screen overlay you can put on or remove as needed as long as it doesn't interfere with your touch screen options.
Ultimately, these devices were meant for replacement every 2 to 3 years so if you're like me and you like to make your investment last, best thing to do is apply any work around you can come up with. A repair shop may be able to wipe the circuit boards down with a solution that clears away corrosion, but it won't repair any weakened pixels. I'm still using a Samsung S5 G900F
- And i finally got this fixed. it sounds like the reason for this is that since the latest update your phone cannot decide whether to use hardware or software back light settings. I managed to make the problem go away by doing this:
Go to settings >> system >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
and then go back to Settings >> system >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen adjustments. no more flickering.
but If I turn the brightness ALL the way down, it still flickers like crazy, however, if that's the only time it'll do it, I consider that a win.
