Blotches on an all black screen? Test yours here

Can you guys with cameras that have manual control test something for me?
Following on from a post by someone else about weird blotches on an all black image displayed on the screen, I checked mine today in pitch darkness and noticed a faint 2 inch or so of blackness on one edge of the screen along with smaller blotches. It doesn't appear to be as visible as the other poster's though but I exaggerated in in the photo so it's easier to see and settings posted below for people to check as well.
This is only visible on an all black screen. This does not exist on any of the S2's I've owned. I'll check my dad's S3 tonight when I go see him in the same way but the way to photograph it to keep the results consistent are as follows:
Stick camera and phone in a cupboard and...
Phone screen brightness: 50%
Camera ISO: 200
Camera Shutter: 15 seconds
Camera Aperture: f/4.5
Remember to pre-focus and use the 10sec timer to avoid shake
Those settings will over exaggerate the effect as shown in my photo below but it makes it easier for everyone to see as you do have to focus your eyes in reality and it's not immediately obvious unless you're in pitch darkness and looking at an all black screen.
I don't know how I feel about this though but if it's visible using the above camera settings for lots of people then I'll leave it as is.
Again, it's only visible on an all black screen so make sure your image that you load is all black and not grey or something Make sure screen timeout is set to at least a minute to avoid the screen going off!

Thanks!

I used this free app to notice my blotches. It worked great for me. Your method has alot of steps in my opinion.
If I have assisted you, please press Thanks button.

What free app? It's a black image with screen timeout extended. The rest is your camera settings to be able to fairly photograph the screen for everyone to compare, an app can't do that

Which free app? What exactly did you do in order to notice them?

Did you see these threads Robbie?

I didn't see those nope! Thanks for the links. Seems strange though as the white S3 belonging to my dad has none of the blotches, neither does a pebble blue on another forum. My 2 S2 handsets had no issues either.
Oh well!

My first phone: (F/4, ISO 800, 20sec)
Second phone: (F/4, ISO 800, 30sec)
The guy at the store (**** Smith in Australia) was unable to reproduce the issue in-store, so swapped the phone out and said I'd have to go to samsung if I reported the same issue again. The 2nd phone still has the issue, but as you can see, nowhere near as bad... still... not very good is it.
My 2 year SGS1 had about 4 spots - never noticed any issue. The first SGS3 was definitely noticeable just scrolling through system menus at night.

That's rather bad^^ I've emailed mobiflefun with picture so let's see what they say.

Suggest you up your exposure (duration and/or ISO) to make it a bit more noticeable. Looks like you've got a fair amount of guff in the top-left corner.
:/ dodgy manufacturing.

I don't have an SGSIII yet, but I noticed pretty much this same thing on my Galaxy Note. One night I was viewing an image with an all black screen and it had these weird blotches on the screen. I had never noticed them before.

Actually mine does has it as well but I can't seem to see it under normal conditions

I have it too. Looks like a crack from the inside out on the bottom left corner.
I can see it in Settings/led notification screen at the bottom at night with screen brightness low.

My 4 GNexus did.

Wow this looks like a widespread issue. Samsung needs to know about this

I assume samsung knew even before shipping the units.

This "issue" is known since the SGS1. Is the leakege from the AMOLED display. One thing to consider i only have a line about half a CM in the same place where you have the circle mark. Maybe a manufacture failure?

quicker way to test.
1 - dark room
2 set auto brightness off and screen to lowest brightness.
go to phone and dial *#0*#
click vibrate test which will display black screen.
and then check....
p.s been through this in other threads here but mky local telco had 26 with this issue went to another telco and got a blue one today - and no issue whatsoever...

Yellow screen ?

Hi, i have one question for n4 owners.
When you look at your phone like this :
Is the screen look a little bit yellow ?
I hope is not a problem, juste ips technology :fingers-crossed:

410 err on the photo but it's probably uncured glue
if so, it'll fix itself unless you constantly overheat your phone (benchmarks and games)
>90% of the time it'll fix itself in a week or two,
it happens with the first batch or two of every phone launch because they didn't have enough time from screen production to sale for all of the units to fully cure.

When I look at it in line of the bottom left corner the screen looks a bit yellow. Every other corner is fine. Its not a problem it will work itself out in a few days.

I don't know if it's a glue problem.
It's look like screen problem :/ but i want to know if others users have same thing.

Yes bottom left and upper right you too ?

I am having the same issue, but i do not need to look from that angle. I see the yellow tone in the options menu just looking directly in front of the phone during normal use. Mainly in the left bottom corner but most of the bottom part I would say.

I'm assuming this is the nature of the screen technology. Mine does this looking at it from the bottom left or top right corner.

Y es i have this problem, and the colors where off, i think the gamma value is high. I hope an update because all have the yellowish screen, i dont think is glue for all at the bottom on the screen.

Mine is like that too

could you upload a bigger pic, or someone else? my htc one s looked super cold when viewing from the sides lol. that's do to amoled though.

Mine is like that too same angle, every other angle is perfect. i think its on all of them.

I didnt have this issue and i ran couple benchmarks. I did heat up slightly and the scores sucked

So you think is gone because of heat ?

I order mine, but im waiting for shipping, when I get it, i will turn on and then I'll check the angle and I let you know if this is natural.

I have the yellow tint too if I hold the phone diagonal en look at the surface.

Bleu tint web you look opposite no?
Someone know where contact Google ?

Mine is yellow tinted regardless of angle. I'm hoping this is incurred glue, obviously.
I compared against my Atrix last night & it's very obvious.
Sent from my Nexus 4 using xda premium

If I was to buy the phone in a couple of days would the yellow tint issue be solved as the phone would have been unused stock for a good week allowing enough time for glue to settle?

I'm having problems with my screen as well. Black levels are off and everything has a yellowish grey tint. I have an Optimus G next to it on the left so you can compare, as both of these phones use the same panel. Both phones are on max brightness.

[Q] What Does A Nexus Without Backlight Bleed Look Like?

I've seen numerous complaints about backlight bleeding, and a few pictures of what terrible backlight bleeding looks like.
However, I've not seen any pictures of either little or none backlight bleeding. Does anyone have a picture (or can someone who has a good Nexus 10 take a picture) of a Nexus 10 with none/low backlight bleeding?
I think it'd be a good reference for those hunting for a good Nexus 10. I'm in the camp that doesn't believe there is such a thing as NO backlight bleeding, but I want to see what is deemed "acceptable" by most so that I know if my Nexus 10 is "return worthy" or not.
Here are a few pictures of mine with its backlight bleed. I'm not sure if this is considered as good as it gets or if I should take it back and try for better?
100% brightness, white backlight bleeding in red, dark patch underneath the front camera in blue:

Another picture without the markings in the way:
Sort of an inverted picture to help show the trouble spots a bit better:

I would say that mine is almost same as yours, I don't have that much light bleed on top of the screen ( close to the camera lens )
I have 2 more days to decide if I return or not, this is my second unit, first one was even worse than I have now. Fortunately bought in Staples, so I just walk in store and exchanged it. Hope more people will post their screens. Thank you for this post.

I'm bumping this thread hoping someone would post a nexus 10 without any or minimal backlight bleeding. I'm planning to buy next week and I want to know if its worth it. I'm from the Philippines and consumer protection laws aren't great here and I'd probably get stuck with what I will get. Thanks in advance!

Here's a pic of my Nexus 10 app drawer. Pic was taken in a dark room with max brightness.

Google sent me a 2nd one no problem for light bleed. However the replacement was much worse.
My mother got her replacement yesterday and was much better better but still had bleed, she is keeping hers.
It seems to be a gamble.

I dont have the bottom left screen bleeding. And the rest are better than yours. But my WiFi sucks....

Light bleed ANSWER FOUND

I got an10 and I would like to know how to tell if there is light bleed? I've seen people speak of it but I don't see where anyone says how to check if I have it and I only have a few days left before I can return it. thanks to those who may help me cue in on this problem to see if I have it.

Download a light bleed app from Google Play and shut the lights off and see.

Fair warning, though: be prepared to contract a bad case of OCD.

NO. WHY?
All caps aside, if you don't notice it I wouldn't look for it. Because once you find it, it'll probably stick to your mind for a long time.

Exactly right. If light bleed is so bad that it really bothers you then by all means return the device and try to get a better one, but if you can't even tell if the problem exists don't go looking for it. All you have to gain is dissatisfaction with an otherwise good device. Watch some movies, use the device as you normally would, and if it looks good to you don't worry about light bleed again.

Or you have the same experience I had. Little to no appreciable light bleed. My first N10 had none, but had a small fracture/defect in the glass (you'll see my image in the light bleed forum).
Second one, a nickle sized but very dim bleed and only seen when in a closet with the door closed and no light.
Acceptable.

Loving mine. I have a small "chipping" in the top glass, also minimal light bleed.

I took another picture the other day in a closet, since the first one I posted in another thread gave the screen a purplish glow due to the angle. Also, the Backlight Bleed app icons were at the bottom of the screen so I turned the N10 upside down for this one. The white icons are overexposed, which I suppose means the bleed in the photo may be exaggerated to some extent, but it seems pretty accurate as to the extent itself. Again, 100% brightness in a dark closet. I'm telling myself I can live with it.

If you go looking for a problem - you will find one. Even if there was not one to begin with.

I am on my 6th unit. I've had it for a week, and I've been using it constantly. It appeared to have minimal bleeding upon opening. After a week of "breaking it in," however, the bleed in the bottom left corner is quite apparent. Anything brighter than auto-brightness and it's noticeable in any setting or on any screen. I'm just tired of gambling with every return. I mean...this is my 6th one. *lol*
Judge for yourself.

Screen pressure under front camera?

On the top left corner of my screen on the nav bar, right below the camera/proximity sensor I see what appears to be just a slight bit of pressure on the screen causing it to be slightly brighter . It's barely visible, and I'm not talking about the light bleed issue from the secondary display, because this is on the other side. It's very faint, and I can't see it when the screen background is dark or if the screen is off. It can best be seen by tilting the phone forward.
Has anyone else experienced this?

Yes I have a black bar under my front camera, proximity sensor area. If I look up from bottom to top of screen it's lighter. I had mine warrantied out today from T-Mobile

I had that issue with my first V20 from AT&T. I went to AT&T and they changed it out at no cost. I get a new one and it has a new screen 'pressure' located on the bottom corners. Makes black look a little grey in the corners.

It's on mines also, but it's a dark spot instead of a brighter spot. Right above over the status bar, you can even see it in white pics too. Wanted to send it to LG so I can get a replacement but want to know if it's fixable first.

I have this too and I wonder if it is from the CPU/GPU heating up. If you look at the ifixit teardown, that is approximately where the heat outlets. I have it on mine. It was day 1 and I was flashing some roms.

Yeah it's mostly when I flash ROMs especially AOKP or LOS. I'm thinking it's a backlight problem, because when I go back to stock it doesn't show... And it could be the CPU/GPU also because during flashing ROMs that part specifically gets warm.

Maybe you are right. I didn't see it in stock but it's super prominent in LOS. I was flashing roms for like 4 hours though. Not sure what is the exact issue.

Alright so I reverted to stock and locked the bootloader and everything. That dark spot is just as present in the stock ROM. The T-Mobile store representative agreed it was an issue. Now I gotta ship it back and wait for the replacement. Just got it a day ago man. :crying:

JFYI...have it here too.

My replacement V20 has the exact same thing?!?! Dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.

I'm experiencing the same thing with my V20. I can see a dark spot under the proximity sensor. Did anyone get it fixed somehow through a replacement or repair through LG?

Have any of you used a simple free screen test app to help confirm the "fault" you seem to have?

Hi Guys. I Just recently bought an LG V20 and have a similar issue. It doesn't affect day to day use but was wondering if it is normal because of the 2nd screen?

I have that same issue ^ not as burnt though but same place and shape. No screen retention at all from what I can tell, just this!
Hasn't bothered me enough yet to do anything, can only really see it on white screens.

Same

It isn't pressure spots - it's IPS light bleed. With regards to the darker patch just underneath the second screen - this is because of light differences between the main panel lighting and the second screen lighting (and again, because it is IPS, the light bleeds over if the second screen is brighter than the main screen).
