Screen marks only noticeable on low brightness dark screen

I have a relatively new (1w) sgs3 and have notice that in the dark room when screen has a darkish grey too off-black background solid colour (even on the stock notification background) and with tge brightness on lowest setting,then there many blob marks in the screen.
I ran a pixel checker which is fine but this appears like a defect in the glass itself. I'm not using a screen protector yet.
Can anyone else notice these blobs, some of which are as big as 3-4mm diameters?

Its completely normal on Super Amoled screens. I have them but it doesn't bother me since it only occurs on black screens. FYI, there was already a lot of topics about this already...

Haven't seen it on the SIII, but on the SII I have, this would happen with screen filter on lower brightness. I think that it has something to do with the level at which the pixels fire optimally. If they are under fed, essentially, the inherent flaws in the screen matrix (as in any manufactured item) become visible where they otherwise wouldn't.

I know this has been beaten to death, but it varies from phone to phone. My i9300 had a lot of blobs. My second one only really has one noticeable one. My i747 is almost perfect. It has little dots, but they are spread out and pretty much near the border of the screen. I wish it would have been the other way around...

please search before posting this topic has been discussed in great detail in another thread.

common on super amoled hd panels.

Same issue too. Checked with Samsung and they said it's common for the screen. Only occurs in black pictures low back light and dark room and it doesn't bother me

Is your screen so damn yellow?

I don't have my Nexus 4 yet but I'm very concerned about the extremely warm tones I've been watching on some nexus 4 reviews, maybe some screens are defective? Does your screen have a yellow tone? Are the whites yellowish? I'm very unhappy with my Galaxy Nexus screen because the yellow tone of its screen, this could be a deal breaker for me, is there an app or something to give the screen a colder tone? Aka more blueish not as crazy as the galaxy s iii but you get the idea
Check out this comparison between nexus 4 and galaxy nexus for example

For me, if your looking at the phone directly there is no yellow tone, but once you angle it there is some yellow then turns back into regular white. (this gets really yellow when you do this while looking from any corner of the phone) not sure if that makes any sense.
EDIT: i see most reviewers on youtube have it at an angle and makes it look really yellow.
not sure why its like that. maybe it has something to do with the glue lg uses?

The question is : is someone don't have this damn yellow tint from angle views ?

The phone dims quickly at an angle. Which keeps from bothering people next to you at night. I like it.

Slight yellowing when looking from bottom left or top right corners.
Looks slightly blue when looking from bottom right or top left.
No discolouration at all when looking head-on.
I think it's just how the pixels are aligned in the screen, it was built like that.

Thank you for explaining this.

I've said it before and I'll say it again: It's going to vary from unit to unit.
I've compared four iPhone 4's side and they all had dramatically different color casts from one another.

Just compared my Nexus 4 to an iPhone 5 and an iPhone 4S in the Apple Store yesterday, this screen is definitely a bit warmer than Apple's displays. It is sort of yellowish on white pages, but the iPhone's were a bit bluer so it all depends on the software.

It's like you guys are looking for any issue. You can find a flat in any product in this world. The sky is definitely not falling and this a non issue. Just use the damn phone. Lol

Huge screen issue with i9505

I bought an i9505 today. I noticed very bad scrolling artifacts especially on a black background. This can be best seen when scrolling up and down in a menue in the preferences. The white letters on black background smear alot. This effect gets worse when turning brightness down. The responsiveness of the s4 display seem quite bad. The s3, which i also own does a whole lot better in this regard.
Can other S4 owners confirm this problem? Has the octa the same problem? Main reason i bought this phone was the oled display. I am quite dissapointed.

something is definitely wrong with it. exchange it immediately in case something is wrong with the second one.

Mine does it too. Most noticeable scrolling through contacts.
Sent from my GT-I9505 using XDA Premium HD app

So if I am not the only one experiencing this it seems to be an inherent problem of the new amoled. In theory amoled has a very fast response time. Maybe it has to do with the fact that the s4 displays true black i.e. the screen is absolutely black in black areas of the screen. The s3 does not turn the pixels completely off, it has blacker blacks than lcd but no absolute blacks like the s4. I am sure Samsung did this for a reason in th s3, maybe to avoid the problem we are experiencing with the s4. I wonder why none of the reviews reports about this issue.

Mine doesn't smear when scrolling unless you mean if you scroll fast it looks smeared? I put that down to scrolling quicker than my eyes can focus if yours is smearing when moving slowly then I'd swap it!
Sent from my GT-I9505 using XDA Premium HD app

The effect can be best seen on black background with brightness set to low. For example when scrolling in preferences watch the horizontal grey sepparation lines. When scrolling slowly the almost dissapear on my phone. So maybe one should not call it smearing but there clearly visible moving arifacts on my phone.

I have the same problem. It is annoying in black backgrounds whith grey letters.

I noticed this straight away and started a thread here http://forum.xda-developers.com/showthread.php?t=2252445 (5 pages long already)
My S3 does not suffer with this problem at all.
The screen is a step down apart from the blacks which are much deeper.

My issue: the red subpixels stay on, this is the SGS4 and SGS2 viewing the same 100% black image.
The effect is a bit more dramatic on these pics than real life, to get a proper exposure. The red pixels are only at low intensity, but it's still easily noticeable.

Hi.
I had the same problem with I9505OXAAMDE firmware. I update firmware to I9505OXAAMDM and subpixels are ok. Now my screen is black, but now i have smearing in setup menu and contact.
I hope that in the future fix this problem.
regards

Interesting. You did not have the 'smearing' before? Because I do see some of that also. On i9505-XXUAMDF.

In the previous firmware did not have smearing.

Old post but mine dose it too!! Galaxy s5

proving Oled (amoled brand name) superior unlike what your told by mainstream media!

Your told, lcd is brighter in sunlight which is the main reason your tokd Lcd is superior or at least thay say amoled is inferior. Wrong,its because if default settings by the makers. Once rooted with proper kernel(almost every device has em) you can do with amoled what you cant do with lcd. Double the color multipliers from android default of 200 to 400. I use in order of RGB, 320/320/400 to achieve perfect white and black. Also the battery myth,lcd drains less. Thats bullcrap. Amiled black pixel achives pure black because its actually OFF. that is main reason it uses less power than lcd. Instead if going on and on I will just show u proof. I will show you picture of my LGOG(sprint optimus g) and my even aging gnex side by side in sunlight with my shadow on half the screens to show its actual sunny lol. A pic says a lot more than my Bloveating. Im using my sgs4 to post this and used its awesome camera tontake the pic if pic does not show in op I will post in first post. Have a great day peeps.

Pics wouldn't attach.must be because of using phone

Pic

2 different pic styles,img and jpeg clearly shows that even with a shattered and pentile matrix amoled screen its brighter in the sunlight. Even did my shadow in it so no one would say....sun wasnt out lmao. Sorry naysayers proof is in the pudding and the gooey pudding is right in front of your face. Proper kernel with amoled is brighter and better battery saver than lcd. Lcd is backlit anyway and most high end phones will use it in the future because it can be bended and manipulated and LCD can't because it is backlit. Only low end phones will be lcd in the future.

I agree with what you've said (I use Samsung phones primarily), but it is true that when displaying white, it uses 3x as much power as an LCD. On mostly black, you're correct; very little power draw.

Tell me about AMOLED burn-in. Since you are increasing the luminosity, I would suspect that burn-in would be faster?

Keeping my eye out for this one...very interesting.
Do you guys mind if I ask what this "burn-in" is and how to fo about it?
Very interesting indeed.

Similar to plasma screen televisions, if you leave an image on the screen for a long time (much more than average), you'll see remnants of it permanently. However, if it's anything like televisions, you can fix it by displaying a white image on the screen (entirely white) for a few hours. I've never had this happen to me and ive owned almost all major Samsung phones. Nexus S, Galaxy Nexus, Galaxy S II, Galaxy S III, Note 2, and now S4.

burn in
Yes burn in can occur on older like the gnex. Newer amoled is less likely but always set time out of 2 min when color multipliers are set to max. Best settings,for pure white is ,320,320,400 rgb color multipliers. Sorry should have talked about burn in,my apologies .

of course

Just remember in all aspects except maybe battery power AMOLED is superior if your rooted and have a proper kernel (there there look for em) amoled is superior and infinitely more controable then LCD, period. Sorry naysayers look at proof in sunlight

Dynamic: bluish tint but not as notable as my old GSIII.
Standard: Still a little bluish but it is barely notable.
Professional: White but WHITE man it may be 200 Kelvin away from the 6500 standard.
Movie: well this one does indeed look yellowish to me but not even enough to note it in an everyday basis.
Read the displaymate review dudes best amoled screen ever with calibration almost near the Adobe sRGB standard.

That one of the only things that I hate about Samsung, because almost all their products are either manufactured in different places or use different internals for the same phone quality standards just seem to vary too much between each one.

Korea, China, Vietnam.
Battery origin:

the yellow tint you can see on black background I only see in Samsung Apps like Messages, Settings and so on. If I'm in an non Samsung App I GOT TOTAL BLACK even when viewing it in total darkness...
so I don't think its a hardware defect more an software thing...
just to be sure i tested with an LCD/AMOLED screen tester app and when showing the black IT's ALL BLACK
I don't see any uneven tint in gray, white or any other color..... ONLY the yellow uneven tint on black background in settings, messaging...
I've had over 10 difference NOTE 3 in my hands trough work and the all had the same yellow tint
ohh one more thing this is ONLY REALLY VISIBLE IN POOR LIGHTNING OR DARK ENVIRONMENTS

I notice it in the play store and chrome too...

I used to have a Galaxy Nexus which suffered from a yellow tint problem. I got several replacement units but they were all the same. My carrier refused to acknowledge it as a fault until a few months later when I saw a friend's Galaxy Nexus without the issue. I took a photo of the two phones side-by-side and sent it to my carrier. They finally admitted the problem and sent me a Galaxy Note 2 as a replacement phone.
I think that there are sometimes manufacturing issues with amoled screens. In my case, there was clearly an entire batch of phones with the problem.
The best thing to do is to go to a retailer (not the same retailer where you bought yours) and ask them nicely to show you a Galaxy Note 3 so you can compare the quality of the screen. Take a digital camera with you and if the units are different, take a photo of them side-by-side. Sent the photo to the retailer you got your phone from, or to Samsung (assuming you haven't tripped the Knox flag and if you have you might be covered anyway if you're in the EU) and ask for a replacement from a different batch.

I have a sm n900w8, an? the acreen is perfect, black is always black, white is always white, where did you get your phone? this might be a software issue, some apps rendering those wrong colors, otherwise take your device to your retailer or carrier

Just Remove the phone from Power Saving Mode - The Yellow tint will go away
