Spots on black screen? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

When ever my screen goes black in been opening apps or websites, I notice that there are lighter spots or smears, but they only show up on the black screen. Does anybody else have this, and or know what it is? besides on black screens, it really doesn't affect anything, but I worry it might get worse

Do a search for "blobs"
There are quite a few posts on it. Some phones are worse than others. Both of our skyrockets have small identical blobs

Sadly after 5 sr phones now having some sort of issue I don't think you will find a cure all solution that includes keeping the sr
The lines drove me crazy . . The blobs (in my case) I never see

The lines are driving me insane as well. The blobs are noticeable in clockwork mod in the dark. I see like a bunch of black dots on my screen everywhere.... Damn.. is Samsung planning on fixing this issue for our phones?

They say they are "looking into it."

I only ever see the blobs on otherwise black screens if my eyes are very dark-adjusted. One example is if the phone is off and charging, and I wake it up (but don't turn it on) in the middle of the night.
That is: the blobs are the next best thing to a non-issue for me. The lines are a minor annoyance that I can ignore easily enough under almost all circumstance.
Both exist though, and don't let anyone tell you otherwise. A little disappointing to be sure.

I've found that the best way to evaluate your phone for blobs is to take your phone, set it to the lowest brightness setting, use the Gallery to display the color #101010 on it, put the phone in a dark room, then use a DSLR camera on the no-flash setting to take a picture of it. You need to have NO light at all coming from anywhere else, so a closet or internal room with a counter works best. It'll take about 10 seconds to capture, during which the phone and the camera need to be perfectly still.
Ignore the green tint - it's a side-effect of the overexposure.
My results:
Phone 1: My mother's Skyrocket, purchased about a year ago.
Phone 2: My Skyrocket, purchased about 6mos ago. I gave the link for this image to an AT&T Rep in the Warranty dep't, and got an RMA ready within 10 minutes.

Lines on Screen, please help

Whenever I turn on my screen, I see lines or a fuzzy gray box flashing across my screen. They go away in less than a second, but I am afraid that my screen is broken. This also happened on my first charge, so I was wondering if the cause could be my battery which I bought on ebay (samsung 1500mah). Also, my new phone almost never connects to 4g even though my old one got full bars.
Please help, I googled my problem and came up with nothing. I still have my first phone, could I send back the same phone they sent me in the box?
Thank you.
What you see on your screen is apparently common for other charge owners myself included. Saw it mentioned as screen "static"in a thread on here somewhere which it can look like sometimes. I don't think it's been associated with any screen issues so I wouldn't trip on it too hard over it. I'll take that quirky behavior with the screen quality!

Pixel Density Issue?

Its not something a screen cap can show due to photos I took on my OGSII looked great on it and like crap on the skyrocket. I'm hoping there's a fix for this?

I cant but its like streeks of lines it almost look like a school of dead pixels but only can be seen on low lighting. im taking it back
I think he's talking about the vertical lines of lower brightness you can see when the screen is dim especially in the gray. I think that's a problem with all plus displays.

I switched back to oggs2 no screen issue... I tried.

It's a known issue with the T-Mobile GS2 that also affects the Skyrocket.
Mine has it also. Most or all have it to some degree.
To see it best, just set your display to about 1/3 brightness and then drop down the notification bar and look at the lower solid grey portion. You'll see the verticle lines/haziness.
I had the same issue with my Atrix but I haven't seen it yet with my G2S.
Maybe it's a quality issue. I've had my Skyrocket for a few days now and didn't notice a single problem with the screen. I was aware of this issue with the T-mobile version so when I switched my OGS2 to the Skyrocket I kept checking for this screen problem. On the other hand my office mate bought a Skyrocket and he noticed the problem that the OP was having. He returned it the next day, got a new one and no problem since.
I am guessing the reason this effects the T-Mobile version and this one is due to the stretching of the screen to 4.5" and staying at a resolution of 800X480.

Screen problem ignorance

It is pretty crazy how people who have the skyrocket ignore that the screen looks awful when dim. Its even worse that Samsung has not stopped production to fix the problem either. You would think the white one would come with a fixed screen. Usually by this time you have people writing reviews and ranting about phone defects on YouTube, yet with this phone nothing. Just hoping someone agrees with me and maybe we can stick these problem up samsungs behind.

Dont think anyone cares that much
Why use the screen dimmed? Kinda defeats the purpose of having a super amoled

Agreed.
I have mine set at 50% and its bright enough for me all the time.
I never go lower than that though, so I personally never experience poor screen quality.

I've never notice the problems mentioned throughout the forum regarding dim settings and colors/lines. I'm sure that to a good eye mine is too afflicted.
One a side note, took my screen protector off today, and man! is that screen gorgeous. It's gonna be hard to put it back on, but I learned that lesson with the Atrix when I took it's protection off and it hit the ground.
You see, and that is the problem. You are ignoring to issue. So when your in a dark room you have your screen full brightness? I don't so it does bother me.

I agree my screen sucks at low brightness. I mainly run my low to save power only turn it up when outside. I wrote a review on Samsung site and did give a bad review on the screen.

I just picked up a white skyrocket yesterday and I've got the screen issues / lines. Looks like a "brushed metal" overlay on top of everything.
I'm going to be getting it exchanged for a new one tomorrow.

Maybe I got lucky... I've had my I727-SR for about 4wks now and haven't experienced the screen lines / screen problems others are posting.... I consistently run at low brightness with a screen protector and screen looks perfect.... no lines, blobs or other anomalies.

Mine has it. So does the white one I looked at. It bothers me and I notice it often. But its the only phone on AT&T that I want and LTE just went live a week ago. I will sadly have to live with it :-(

My screen is great. No lines or any of that kind of stuff.

just picked one up today. white one.
i see the lines below 50% brightness. above, they are gone.
I believe this is just a simple issue of having the same pixel density of the galaxy S2 but with a larger screen.
this should be device wide.......i dont see why people should have different results....
edit: i have it only above 30% brightness actually....
No problems here... at 0 it still looks great, no lines or weird issues

I have personally seen this vary from device to device. what may not be that bad on yours could be 20x's worse on another. others of us are in fact picky and expect more for what we paid for this device.
To each their own

playing video
When I play video ie Netflix YouTube etc I notice that the picture quality is not.what I expect.from a 250$ phone. I love this phone and that is.my only complaint. I have tried.adjusting.the brightness but it doesn't seem to help. Is this a problem that all are having?
I just got the Skyrocket today and just now turned the brightness all the way down and did not see any issues with screen clarity. Looks pretty good to me.
Infused with Android DNA
Mine has the same issues. However, they are ignorable if you customize the look of your phone. I changed the screen density and customized my phone with a dark bg and modified system apks.

Black spots

Hey, I just got a gs3 today. I noticed that on really dark greys(basically never) I can see these black spots around mid lower region of the screen. If I use the app "screen filter" and set it to around 2% I can clearly see them. Can someone else try it out so I know if its my phone or not?
Thanks

I know I have some black spots on my phone I just got today as well. Can see them on low brightness with dark background. Is this normal? Reminds me of the nexus. The screen is better though.

yeah not sure, if it isn't I'm gonna have to return it and get a new one. Definitely not getting stuck in an endless CLN replacement loop.
Sent from my SCH-I535 using xda premium
I'm gonna go ahead and say it's normal at low brightness seeing how I've had three brand new nexuses and six replacements and all of them had black spots and there was a thread. What's normal on your screen and what isn't. And they marked this as normal.
Even if you go in and swap it promise you the new one you get will also have black spots. Not just saying that.

Have same issue got new s3 and there are good few of them. I also did some research and it's basicly the amoled screen what causing this problem. Not sure now if should i swap it or not. New one might be even worste

Its very common.. I guess its on all devices that use the same screen as the SIII, I think amoled. Anyways, the two devices I have had both had it, I'd say if their not HUGE and you dont notice them unless your in a dark room then its not a big deal. But its totally up to you. I think they are called ink marks as well.
Mine has a few also that are most visible when a youtube video is loading (that dark grey screen that's not quite pure black). It's not very noticeable and I hardly see them so I'm not worried
I believe this is pretty common though
That's unfortunate. No black spots to report on mine. Maybe it was part of a bad batch from the factory?
They are there. You just don't know how to look for them.
Every Samsung amoled has them.

[Q] Screen Flicker?

I haven't seen anything else posted, but I wanted to see is anyone is having the same issue as I am.
Basically, I'm getting what I think are row's of pixels flickering in the area of the screen that are gray.
Here is a quick vid trying to capture it. I can't post videos because I have less than 10 post, you are going to have to trust me for now...
I've also used the dead pixel finder app...everything looks good until I change over to a gray screen, if I stare at it, I can see the flicker...
I first noticed it when I flash Franco r10 (which is what I was on in the video). When I flash back to stock kernel or Bricked, it's much better. But now that I know it is there, I can still see it.
Anyone else having this issue? is there a fix or should I just send it back?
If it matters... LG-D820 White, 32gb
I'm guessing I'm alone with this issue and that it is a hardware problem. :thumbdown:

I haven't noticed anything on mine, but I haven't flashed anything yet. Did you notice the flicker before you flashed the first time?
No I didn't notice anything until I flashed r10. But now that I'm looking for it, I can see it on stock and bricked ever so slightly.
I could live with it on the stock colors, but if this is hardware, I worry that it is going to get worse and not better over time.

I have the same issue and saw it as soon as I flashed franco kernel. Noticed that if you set brightness to 100% it will slowly stabilize but will still come back when lowing brightness. I called for an RMA, but cannot reproduce it as obviously on stock, so i'm also lost as to what it could be.
What did you end up doing?
On mine, I could see it on Stock colors, just not as bad... I returned mine on rma....
I recommend getting the app called display tester.
I don't have enough post for a proper link.
https:// play.google.com /store/apps/details?id=com.gombosdev. displaytester
Look for a bad pixel and go under the banding section for reason for rma.
My new phone didn't have any of the flicker /banding that my old phone did.
Good luck..

Sorry to bring back an old thread but I just noticed this not too long ago and didn't want to open a new thread. I noticed it while I was on stock first and thought flashing something might fix it. I've had mine since the beginning of November. Is the best option just to RMA it?
Sent from my Nexus 5 using Tapatalk
can you use a SlimPort cable or chromecast to mirror the screen to a TV and see if the flicker still happens?
So you'll know if the problem is in GPU or screen?!
