[Q] Problem with light bleeding (kind of) at the right of the screen

Anyone else noticed this issue ??
There is a spot at the right (in the red circle ) which is quite brighter.
This is noticeable only in bright backgrounds (white websites, market etc..)
You can not notice it at all on black or other dark backgrounds (youtube app etc..)

Mate, you should look at the screen on the Transformer in a darkened room.
Believe me, that's lightbleed, but not as we know it.
Search youtube for asus eee pad transformer lightbleed issue and see what I mean

I returned my first A500 because it had really bad light bleed. I guess that's what you would call it, but its like the opposite of the other tablets blight bleed complaint, noticeable on white backgrounds but went away with dark ones.

Either way, if it's a fault which spoils your enjoyment of the product then it's not acceptable in a product at this price point.
I returned 3 transformers with the same issue before I got pi$$ed off enough to ask for a refund.
Take it back if you are not happy and email support, they will only know about a potential issue if people are scrupulous about quality control.

I have the same problem so I took the a500 back to best buy for an exchange. The geek quad guy looked at the tablet and told me it is normal and refused the exchange. According to him, there is a light bulb that runs across the screen and the bright spot is the result of close contact between the bulb and the screen. He said that I could either return it or keep it but no exchange. His reason, once the tablet is opened, it can't be sold to other customers and he does not want me to end up return the exchanged tablet which will hurt the company's profit. I was like, sure, the iconia is the only product in the store and by the way, you should be an employee of the month for looking after best buy like that.

I really have noticed this issue on every device i ever held in my hands !!
This must be some general problem.. !!
How about everyone else??
i m really surprised that only a few people reported back on this issue !!

My screen does not have this problem. Maybe your screens are too tight? In fact my Asus netbook does have this problem, (kind of), because it's backlit by LEDs.
Does anyone know what the backlighting is on these Iconias? Did anyone take one apart?

I also noticed this a bit when I was doing some pdf reading with the tablet vertically oriented. Pretty much the exact same spot, but it sounds like it was manufactured that way by the responses of some of the other people on here.

Same problem here at the same spot. Pretty annoying when reading e-books for example. Is there something we can do ?

Nexus 7 brightness problems

Just got the nexus 7, but...
When I change the brightness through the power-control widget or settings/brightness, on or close to the lowest level it turns off the display completely. I can't see anything no matter what the lighting condition is. Is this a software bug? I don't see how I can turn it back easily.
Another problem, when reading book, the light from the left bezel bleeds and I have a darker top-left corner. It is kind of annoying.
I also have the flickering problem when the brightness is set on the mid brightness... software updated right after startup.

Anyone have the screen completely off when turning the brightness down?
I also happen to have eight stuck (white) pixels...

Yeah, I have a very similar problem to what you described.
Check out my pics.

My backlight bleeding is very similar.
Does your screen get completely black when the brightness is low? Now, even when I turned on the automatic, it gets complete black. Is it just me or everyone else the same?

No, it does not go black at min brightness here.

I just got the Nexus 7 and the light bleed is Horrendous. I have owned a Asus Transformer before and expect some light bleed but this is really really bad. Like WTF

Mine looked exactly, so I went back to staples for a replacement. Luckily, they have one left. The bleeding on the new one is unnoticeable and the brightness settings are all normal.

Wow. I thought my transformer bled light bad. I'm not feeling so bad now. Of course it has some other weird issues, but has been mostly reliable. If it acts up too much I'll just send it back. I've had it for almost 30 days and can't find any real reason to take it back. It reboots every once in a while if it gets overloaded or too hot (did it today in the sun..of course I had it overclocked too.....) and I've opened the dock to see that it has shut down for some reason, but its not a huge deal. Other users have reported the same, so clearly something isn't perfect. I came to this thread because I heard that the nexus has huge issues. I was curious to see what people were reporting. if I got a nexus like that I would be p****ed! There are reports of them locking up on startup. My transformer just keeps chugging along. Really I've had more problems with apex launcher than ICS on my tf300t.
edit: the light bleed is barely noticable on mine actually...only in darkness does it seem bad. I heard ips displays have issues with that, so took it as good enough for "spec" and really its not all that detractable unless I sit in perfect darkness. Video looks pretty great on the display.

Advice on purchasing the Nexus 7

Hi guys,
I plan to purchase this week a Nexus 7 16GB. Based on the reads, the device could have 2 issues: screen lifting and dead pixels. Can you please let me know if the screen lifting was visible when you actually opened the box or it started to pop after a while? I plan to go at local shop and open the case in front of the salesman, to check for those issues.
If you have any other tips I should check for, please let me know (i.e look for a specific build number etc.). Thanks.

That's a little unnecessary in my opinion. Yeah some people had that problem but it was a small percentage and opening it on front of them isn't going to change anything other than the fact that you can return it faster if something IS wrong with it. But I'm guaranteeing there won't be anything wrong with it

Ya... the idea is to save time and exchange it right away, in case I'm "lucky" to get one device that might have issues.

I was nervous too. I bought one today and it turned out perfect. I believe you would be able to see the lifting almost immediately .

I didn't notice the separation in my first unit for a week. I think it got worse over time, but can't be sure.
My second and third units were more subtle, but because I knew what to look for I was able to spot it straight away. I think that if you get one that's flush out of the box you should be alright.
Go in with some idea about how much lift you're willing to tolerate. If it is only lifted a hair, turn it on and press firmly on the left side of the display to see if there's any distortion. Listen for any sticking or clicking sounds. I'm not convinced that the most insignificant amount of lift will inevitably lead to problems down the road, and in hindsight my second unit was good enough to keep. The third was lifted enough to ripple when pressed in the raised area.
The most effective way to test for screen lift is to hold the device with the right side facing you. Look across the display and use the left bezel as a silver horizon line. If the black display is higher than that line at any point, you'll be able to see it.
Here is an example of a perfectly flush display, looking across the device from the right side.

I did more research, might help others on checking the tablet. So far, the main issues that will bother me are:
1) Screen lifting, follow pxlitup's tip or run your finger across the edge where it meets the silver bezel.
2) Blur or trailing, while viewing the Applications screen see if the icons lag or leave a trail behind when you flip through.
3) Color gamut, mainly Green or Yellow tint due to low quality Hydis IPS LCD displays.
4) Bad solder joint, set the brightness to the lowest to second lowest level, open Google Maps and scroll around to see if the display fluctuates or flickers.
I think I'm going to wait for the new Sharp IPS LCD display, they plan to use it into next batches. If anyone has any inside related to the Sharp screens, please share it with us. Thank you.

Who are you to guarantee that? I've gotten five defective Nexus 7s in a row...so far... It's not that small of a percentage dude. You were just lucky to get a good one haha.

Edge Viewing angle issues?

So after a few days of use, I started noticing that I was unable to see the "People Edge" tab on the right side and while reading pages that were not exactly black in color, it looked like the 'edge' part of the phone looked as if I was looking at a TN panel sideways... So I compared this to my wife's phone and sure enough, it's a problem. On max brightness, I definitely don't get the same colors or anything of that nature, and it's significantly "bluer". Here are a few images for your viewing pleasure. I contacted the local VZW store and they said they'd exchange it once it comes back in stock (within my 14 day period).
** Note ** I did mess with all display settings and the color issue is not correctable.

You'll see the greyish look to it on the edges.. it's driving me freaking crazy. I paid $800 for a ****ing phone so I'm being picky.
If any of you guys are having this issue and within your 14 day grace period, return it and get another.

You're wasting your time if you return it, because the new one will have the same thing. It's a limitation of the design. The only difference is that on some phones the edge "shadow" appears more green, more blue, or more pink.
My S6 Edge had it and so does my S7 Edge. You'll stop noticing it after a few weeks.

My wife's does not have this issue at all, so I don't think that's true... if the one they exchange it for has the same issue, I guess I'll eat the $35 restocking fee and never own an 'Edge' phone again :|

I have never seen an "Edge" phone without this to some degree, but chances are you'll end up with it on the exchange device. Just go look at the demos in the stores
After a few minutes of Googling I again found the official Samsung article explaining this. Took me weeks to find last year when this issue was driving me nuts..
http://www.samsung.com/za/support/skp/faq/1076253
Your device is not faulty. The colors on the curved screen may look different depending on your viewing position.
The slight green tint in colour at the edges of the Galaxy S6 Edge display that you may observe on occasion is due to a phenomenon called WAD (White Angular Dependency) which is due to the inclined curved surface of the S6 Edge screen.
For an AMOLED display, the WAD phenomenon results in the colour white sometimes appearing to have a Green tint, or on occasion a Blue or Yellow tint when viewing the AMOLED at an angle. But when viewing directly from the front or side the colour will be as expected.

Same applies to S7 Edge.

Interesting, thank you very much. Yeah, guess it'll just be a return.
I'm very peculiar with my eyes. I can't wear glasses with my astigmatism because of the odd shapes I see so I doubt it'll just go away.

Glad to help. I was going through exactly what you were last year. Hopefully someone will be searching for this issue and find this thread down the road.
I have astigmatism, too, if it helps. I wear toric contact lenses. Eventually I just somehow learned to ignore the edges. I had forgotten about it until you brought it up.
I found the S7 Edge page as well. Same response...

Well, in that case, I'm glad I was able to help you remember while I try to forget Yeah, only way I can see properly is with contacts as well. I might try to get over this until next Wednesday and if it doesn't happen, it'll be a return.

I would encourage you to do the exchange and see if the new one is slightly better (the tints are all a bit different). Maybe it'll be less noticeable? But then again, the new one might be worse to your eyes. It's a lottery

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).
