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"!

After an Inspire and Focus S, I find the 4.7" display of my Titan too large to easily type in.

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.
Hello guys,
i'm new to the Galaxy Note and the Forum, start by thanking everyone for the great job you have done and are doing.
- Before:
I bought a Galaxy Note, I am fine and i love him like a son (maybe because I have no children).
There was the original version of Android 4.1.2 firmware N7000XXLSA with NO brand.
I flashed from the original recovery kernel that is here (forum.xda-developers.com/showthread.php?t=1901191) to be precise "Philz-cwm6-XXLSA-DBT-v3.99" (I do not know why I chose this among others, perhaps because it reminded me of the original LSA final XXLSA and makes me wonder: the "Philz-cwm6-ZCLS8-CHN-v3.99" is newer than the one I flashed?).
From ClockworkModRecovery I installed, after fullwipe, the last Nightly of CyanogenMod 10.1 and the gapps (as I did on other phones like Nexus S and Nexus 7 and it is always gone smoothly).
- The problem:
Everything works fine (apart from a phenomenon of Battery Drain, but I have to recalibrate it and recharging from consuming it all off for at least 4 hours and then delete the stats etc ...), but there is one thing wrong: the monitor.
The icons on the desktop can be seen very well, ultra bright and the text looks really HD! (I come from Nexus S and I also have the Nexus 7, bright colors and blacks amazing!) But the background, some photos appear, or the shades of black phone menus you see badly.
If I use MXPlayer to see a video all blacks are pixelated, gradients are sheared.
As if it was in safe mode, type windows xp in safe mode that NOT loaded the video card drivers.
I read around on the issue and there was talk of color banding, 16bit software compared to 24bit monitors hardware, but in essence what?
Depends on the kernel?
I have to go in customer care to replace the monitor (which also occasionally changes almost imperceptibly color, for example while navigating, then on the white background of the pages, from white light turns yellow, then brown, and so on).
What do you recommend? Does anyone have or have had the same problem?
UPDATE:
This morning I tried the phone around, the street outside and the problem seems to disappear.
I set auto brightness. So maybe with strong light, increasing the brightness of the blacks are softened better.
Now I'm recovering from the last original software Samsung Kies, the much-hyped premium suite, see what happens and if the problem remains.
Thanks in advance to all.

I recommend go back to a non leak firmware which is not buggy like this one. Then see if you can reproduce. Remember those JB roms are buggy leaks. Best to use the kernel phills made explicitly for the rom version you are running.
Regarding colour changes this usually is due to powersaving apps or settings. Remove and/or disable those. especially the one in the stock browser. This a known old issue not necessary caused by hardware.
battery drain issues van best be analysed according to ahalfords sticky on wakelocks.
I haven't seen people talk about screen issues in a long time. Is this finally resolved?
what screen issue? no issues with the screen here, and i got mine in november.
I had a screen issue where half the screen tint was yellower than the other half. I held off on an RMA. It corrected itself overtime. 64GB Midnight Blue direct from Motorola.
I don't doubt that there were screen issues and I'm sure some owners did have significant problems, but my take on the whole "screen issue" topic was that it was exaggerated. I ordered my device (64GB MB) in December and got it in January and have had no screen issues. AMOLED screens are prone to burn in/image retention, and people are more likely to post if they have a problem rather than no problems. When people need a completely grey screen to notice retention/burn in to complain about they are just looking for something to complain about.
I had the screen issue where 1/2 my screen would freeze. My RMA has been fine and I received it back in December.

Friend of mine had the same issue couple times but then it stopped and now is working fine.
Did someone figure out what was the problem?
Just bought my nexus on Saturday and I am experiencing this issue. What's the likelihood of it being just a software issue? Don't want to exchange it if there's a software fix.
From reading past threads, I know of three 'screen' issues.
1. pink/salmon coloring on low brightness
2. split screen jumbling/distortion
3. burn in/image retention
My phone was manufactured 1/15/2015.
Specifically ordered from tmobile, so midnight blue.
1. I don't have any pinking/salmon tint on lowest brightness. I use the lowest brightness by default and I have looked at a pure white background. This is certainly a more subjective issue.
2. I don't have the split screen bull**** I've seen. That's clearly broken and a hardware issue so send it back for an RMA.
3. Remains to be seen on my phone. I went ahead and disabled the softkeys, and added pie control just in case. I don't think this is 'fixable'.
I have noticed that the pink/salmon coloring on lowest setting varies from one rom to the other. No issues on stock, or stock based Roms. Definitely see it on anything I've flashed that was AOSP built or CM.
Just my experience.
I got my 64gb Midnight Blue yesterday and I've noticed some fine vertical and horizontal lines on the screen.
Its especially visible on white/grey or solid colour images. When scrolling a webpage the contents move but the lines stay stationary. I have a very similar issue as whats shown in this video:

Sadly a by product of AMOLED. I've seen this issue a lot worse on older phones like the early Galaxy S'.
You can probably try to get an RMA, but I suspect that this issue is going to be present in some mild way on most devices.
