Hey guys,
I already mentioned this in the German thread, however it may concern a couple of more people.
I just received my replacement. The reason I ordered one was I got 2-3 tiny little bright spots close to the top right corner on the display. Exactly they are located on the opposite side of the back camera. These pixels are brighter than all others. Though the spots are very tiny you can notice them e.g. if I look closely at the Google search bar on your home screen. It's not that they are disturbing me but I feel on a new device there should not be such issues. You never know how far this is going to get.
So, the today's device is made in Jan 2013 and it has the same spots. I want to ask if anyone of you has the same issue. Just download a pixel test app ( e.g. Dead Pixel Test by Ossibus Software) and look at that area at different angles and colors. I attached a picture to get a better feeling of what I mean.

Sometimes it is better not to go looking for these tiny flaws as often we find them.
LCD panels do have flaws, and a certain number will leave the factory with some broken pixels, some good information here http://en.wikipedia.org/wiki/Defective_pixel
Some applications claim to fix these pixels by flashing the screen with lots of colours, and they seem to work for some people, typically however the pixels are intermittently broken and would have probably just started working anyway!
Manufacturers of LCD panels let a certain amount of screens through with broken pixels simply because otherwise they would be throwing too many away and so their cost would be considerably higher.
I'm not sure if yours are broken pixels however. How are you seeing these? If you are cranking the brightness up to full and viewing a dark colour you can often see tiny pin holes of light, and this is just tiny flaws in the filters which are so thinly applied tiny breaks happen, which you wouldn't see in typical use. You'll never find a screen 100% perfect if it is this you are seeing.
What do you see if you have a dark black background and the phone on normal brightness? Pixels stuck in the "on" position would be very clearly visible. On a white background stuck "off" pixels would be clearly visible, either by showing a tiny black dot, or typically a dot of a different colour.
If you can't notice them in typical use, just don't go looking for them :good:
If they are stuck pixels you have been unlucky, and the only option is another RMA.

Phil
Had a "hot pixel" almost in the same place as yours when I got the phone is December. RMAed it and the replacement is looking good now.

This is good advice. My last 4 phones (captivate, atrix, gnex and N4) all had some kind of defect with the screen. Captivate had slight burn in, atrix and gnex had black spots that can be seen with brightness on lowest in dark room and my N4 has minor screen bleed under the camera.
Its not hard to find problems with LCDs if you look close enough but none of the defects i had could be seen with normal usage so i didnt bother to return them. There is a chance that you will get a replacement with worst defects not to mention all the hassle of having to do a rma. But then again this is xda where people freak out when they see a scratch on the screen.

Thanks, mate.
When it's black I only see light bleeding from the top. Therefore, they are not dead. I believe, during the manufacturing process a layer behind the the pixel gets damaged. I filed for another replacement. However, I don't think it'll get better.
This is probably a really stupid question, but is it normal to be able to see the crystalline structure of the LCD screen on this phone? I just got it replaced today as my old phone was faulty, and basically if you look at this new one either at a slight angle, or when there's a reflection you can see all the small rectanglular structures making up the screen? I don't know if it's just that I never noticed on the previous one I had, or if it's a problem? First noticed it as when the screen is black it looks a bit stripey...
thanks.

Depends on the light and angle (black screen only), my one has the same. These are the capacitive screen sensors, nothing to worry about.

Do you have the JDC screen by any chance? I think it's only on the JDC screen that this occurs. My old one (before this replacement) was a sharp and didn't have this issue. I want to get it replaced but CPW say it's not really a fault as such. But this display is essentially terrible - colours aren't reproduced correctly, if I want to watch a film, everything is somewhat blue and it's essentially unusable outside because of how visible the sensors are.

Have the same issue here. Just bought the Xperia Z a week ago, and the touch sensors(if those are them) over the screen are really visible when outside and the light reflects it, basically makes no sense to have a fhd display if half transparent lines covering it. I have checked other Xperia Zs at phone shops and so far all of them had it. It's pretty annoying, and this is one of the reasons I will ask to exchange mine to an HTC one, aside of the poor battery life. Apart of that striking beautiful design.

Sharp manufactured screen here and the sensors are visible, although just barely, and only when the light hits it in the right (wrong) angle.
Same for me, on my c6602 the sensors are visible at any angle other than direct view. Its a jdc screen.
I also have a c6602 with a sharp screen and the sensors are barely visible. it actually seems like there is more space between the touch sensor and screen which hides them better than the Jdc. Although the Jdc does have better contrast.
Personally I can't stand seeing the touch sensors on the Jdc regardless of contrast and prefer the look of the sharp screen.

Got the Xperia Z yesterday and this issue drives me crazy... in 90% of the time I can see it. Inside, outside, different light environment etc.
It's a JDC display.
Thanks for this thread! JDC screen here too and mine looks exactly the same - I thought that my phone's faulty but now I can see that it's common with this screen producent.. It seems that you either get Sharp with greyish black or JDC with capacitors showing.. what a shame!
Anyone tried to contact Sony about this?
Got it too. No idea what's my screen, but is this something to worry about? I don't see any issues with the screen.

I believe that as long as it does not disturb you, it's not a problem. It won't break the phone in any way. It's mainly a matter of aesthetics, although it may also make reading the screen in direct sunlight more difficult.
Unless I'm mistaken? Anyone wishes to share their thoughts?
In my lower half of the screen I have a bright spot visible only on light background. My device is just a few days old. Anyone else encountered this? Should I worry about it?

Sorry this might seem silly, but have you checked that the lens is clean? Or maybe there is a bit of dust that has gotten inside the casing and onto the lens? I guess if it's bright enough, then you should be able to have it fixed on warranty.
The lens is part of the camera and has nothing to do with the screen. The screens are backlit by a source of light and mine has a bleed spot. I've seen this before on laptops too.
I think I have it too, left side, a little lower then the middle of the screen. It shows better in the brightest screen setting but it's still pretty discreet. I wouldn't worry about it.
talk.sonymobiledotcom/t5/Xperia-Z3-Compact/Lighter-spot-on-screen/m-p/855751
So, I sent the unit back and got a replacement. It was pretty annoying to me as I was constanlty distracted by the bright spot. The carrier (Orange Romania) was very cool about it and sent the replacement ahead to make the switch at my house so I wouldn't have to send it in, wait for them to verify the fault, sent a replacemet in a week or so and be left without a <propper> phone . Very pleased and so far I can't identify any faults.
I received my device today and after playing with it for a few hours, I noticed a light blob on the top-right side of the screen. Such a shame
Hopefully I'll get a replacement asap.
I have a similar spot, but it is in the right bottom corner. These spot seem to appear near the buttons. My theory is that by bending the phone something from the inside of the phone pushes against the display and creates the spots.
mine is from the left edge, thumb size. It's visible on dark background. Sony mobile displays are pure crap, the worst I've seen on any smartphone. Never buy Sony again!
Are you guys experiencing light bleed from the edges of your Note 8 screen. I just got my Tmobile Note 8 yesterday.
Wow...
I was hoping to god this wasn't gonna happen again.. I hated this so much with the Note 7 -_-
It isn't bad at all when the brightness is lowered, but looks absolutely disgusting when using the phone for GPS at night.
Last thing I want is for a $1500 phone to look cheap.
Apparently this is "natural" because of the glass and how it reflects light, BUT... all they had to do was wrap the black around it to block that reflective exit alone the edges.. But they didnt.
I may just take my note 8 back over this. I couldn't stand this on my note 7
OP, you should max the brightness, show a white image, and put a credit card on top of the screen and then take a picture.
Wow! I probably would have never noticed, but I do now. Thanks! I have a VZW but it doesn't seem near as bad as yours. Luckily my case covers it so I won't OCD over it, like the bubble I have in the bottom of my screen protector, going back to geek squad tomorrow. On my s7 edge I made them change it out 3 times. :angel:

You probably aren't noticing it because it takes a relatively bright image closer to the edge for it to appear.
View a white image with maxed brightness while covering the majority of the screen, and you will literally see a white ring around the edge of the phone.
Super damn annoying -_-

After reading this post, I immediately took it out of the case, cranked the brightness up, turned the lights off, opened a web page, seen it! Aghhhh! On mine, it seems worst on the right side. Put it back in the case, took a shot, and now trying to forget it was ever there or my eyes will look for it every time, because it IS ANNOYING now that I KNOW it's there!

If it makes you feel better, its only noticeable when the brightness is at a decent level. Plus using a case will get rid of it entirely.
I'll probably whip out the microscope and apply a fine line of black paint along the edge of the glass lol.
I wonder when they're going to get rid of light bleed. I've literally had it on every device with a screen that I've ever owned.
I thought that OLED devices weren't backlit. Blah blah blah individual pixels lit. Isn't that supposed to be a selling point of OLED screens? Where does the light bleed come from?

It happens because the glass is still thick enough to allow light to travel along the inside and exit throughout the edges.
This is such an easy fix too, which is why I don't understand why this hasn't been fixed. All they have to do is literally wrap the glass around the edges with the same material they're using the the top and sides anyway..

Ahh, ok. Makes sense. Thanks for the explanation. It's different than the standard LCD light bleed then.
Hopefully I won't notice it much while it's in a case.

A blast from the past. Identical thread in the Note 7 and nearly all other forums concerning the 'edge screen design'.
It is not technically "Light bleed" That term is reserved for a phenomena (problem-fault) often common with IPS panels.
What you are seeing is......how can one write.......light escaping NOT into the screen as light bleed but light escaping from the screen.....There is a gap between the body and where the display ends, this tiny tiny tiny space, in certain situations, can indeed shine light OUT but not into the screen and there is a difference but both can be annoying IF we become OCD about it. I guess this situation is part of the edge experience? As suggested by peers, a case will stop such micro reflections or light escaping.

So this is a known issue with Galaxy phones?
I've never experienced it with the Note 7 or currently with the Galaxy S8 plus. Is this enough to get a replacement?
Wow, this thread is like dejavu, I had to really look for it with max brightness in a dark room to find it on both my note 7's. I didn't think it was a big deal but some did. If I get the note 8 I will look for it.

It sounds like you might have to go through more than one replacement to get one that doesn't do it.
Just for fun, I always follow the release of the new iPhone on Macrumors each year, and there's always a huge light bleed thread. I know (now) that this is something completely different than what happens with these phones.. People over there go through numerous replacements to try and get a perfect screen. Many never get one.
I will have my phone in a case from day one, so I guess that I won't see this.
Mine's good... no light bleed at all.
I am getting no light bleed at all. Turned my screen all the way up on a white screen and no light bleed.

I'm not seeing any either even with the brightness turned all the way up and various bright pictures. There's a slight change in brightness but that's to be expected with the curve but nothing like the pictures.

at least one guy on another forum has reported his light bleed and is getting a replacement in exchange.
So maybe some were built with more of a "gap" there than others.
The way my luck with electronic devices works, I'll definitely have it. Glad that it won't be noticeable when it's in a case. I won't even look for it, because then I'll know it's there for sure and it will bug me.
Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.
same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.
Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.
Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge
Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.
I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.
Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!
Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.
