[solved] Xoom screen question

I just ditched my Notion ink Adam for the mighty Xoom. I'm glad to say I'm impressed. Now for the reason behind my post. Is it normal to see a diamond like pattern(what I suspect to be the digitizer) behind the glass.... I first noticed it while playing with the youtube app. The deep black colors gave way to what I thought was just noise from the video, but after looking at it on an angle with the screen off you can definitely see the pattern.
Is this normal? Last I remember seeing a digitizer was on my Mogul.

A small moire type pattern or a large contrast difference pattern. I have seen the large pattern occasionally. It doesn't seem to interfere with actual usage.

it the screen capacitive touch sensors (dunno the technical term). i can see it on just about every touch screen except the ipad - go figure.
the 101 is a crosshatch, the nook color are dots, this xoom is a crosshatch with some kind of checker pattern.

I figured it was normal, just didn't expect it to be so profound. It has no hindering effect on user experience. I hope people don't take this and blow it out of proportion as a flaw...lol

They probably will.. lol I've seen people make issues of of something trivial like a button squeaking when you press it.. I can already picture people saying "my xoom screen is messed up"

yeah the only time you notice it will be on dark scenes/backgrounds with ambient light and holding it at a certain angle. the 101 is more predominant but it's really not a bother.

Bad LCD panel?
Hi everyone. I just bought my wifi-only model from Staples today (Sunday). I noticed a little "problem" with the LCD panel when I turned it on, but disregarded it.
While watching a movie, I noticed the issue in full force. When a movie file is playing and there is a black background, I can see "mini-panels" and it's very distracting. I don't see this on a solid black background without media playing so I'm guessing it's something with the backlight. I'm attaching a photo (glad I was able to capture it this way!).
Anyone else seeing this? I didn't look close enough at the store's display.

And so it begins...

that's the capacitive sensors. i wonder how apple hides theirs.

Ive got them too, didnt notice it on any other devices ive used but its just the capacitor mesh that moto decided to use. My glass almost seems wavy as well (like not 100% flat) so not sure what my feelings are on that yet...

my guess on the waves is that it helps curb reflections.

Yeah what you guys are seeing is definitely the digitizer. On most touch screen devices you can see the digitizer at the right angle and with bright enough light (ie sunlight seems to bring it out the most). My guess is if you test this is a lower light setting you wont see any of the digitizer.
I have also noticed the digitizer on the xoom screen relatively easily.

well, ive just noticed the waves. i usually see small waves on screens but these are warps. good thing i'm trying to pay attention to the image on screen instead of the reflection, lol.

I have seen little warps on the bottom of the screen like 1/3 or the way to the middle and 2/3 to the right side (like a couple inches off center on each side). They are also in the same relative position on the top. My guess is this is how the screen is attached? It would be great if someone could take a good look at theirs, it may take looking at the reflection of light in those spots to actually see the warp, but I would really like to know if it is just mine or it is on all of them. And BTW I see the digitizer too, but it is worse on my HTC inspire 4g.

[Q] Can anyone say they have NO lightbleed?

Received my replacement transformer the other day and thought it was OK on initial inspection, in a darkened room.
But actually, when you pump the brightness up to full, looking at a black screen (downloaded a black jpeg to test it as in the galley app the software buttons fade out so you get a true picture) it is actually no better than the one I sent back.
So my question is, using that system - black jpeg, full brightness, is there anyone out there who has no light bleed, particularly around the bottom left hand corner?
Cos if there is, it looks like this baby is going back to Comet for a second replacement, and if everyone has it, then I guess I will have to assume its a manufacturing 'feature' and just live with it.
Cheers for your help folks.

Glad there is somebody know knows how to test a LCD light bleed properly.
I have the exact same issue. Maybe its part of the design.

Check my post in the other light bleed thread. I'd be happy to explain more if you'd like: http://forum.xda-developers.com/showpost.php?p=13478882&postcount=111

I did everything you said, and see no light bleed in mine. I just got mine today.

Zero light bleed for me as well.

at a very extreme angle i can see a little near the camera. doesn't bother me, i would have never noticed

I mean... you went through all that to find a defect? I know that we all want the perfect device but how often will the light bleed actually affect us?
I think I also have light bleed but I had to tilt the damn thing to find it and it seemed perfectly fine before reading these posts.
Does it really bother you that much that you're even willing to go through the hassle of exchanging it?

I first noticed it when I booted the tablet with the lights out in the room. I don't have any issues in normal use and it doesn't bother me enough that I'd want to send it back.

I just got my 32GB. I didn't notice it during the daytime, but at night I do see a little towards the top. But not to the point where it bothers me.

Got a couple of small spots along the bottom that i could live with only noticeable if you have light off and brightness at full, one of the corners has quite bad bleed, can see it on darkish screens without even turning lights off or even down.
Considering whether to return it.

'All that' is not really all that to be honest. I downloaded a black jpeg and looked at it whilst sat here watching the telly, took about 30 seconds in all to show up a significant level of light leaking in from the bottom corner.
If you have to tilt your unit to find any light then its not going to be a problem for you. On mine it casts a glow on the bottom corner when I am sat with it on my lap in a normal living room with the table lamp on.
For me there is nothing wrong with wanting a perfect device, I am pretty sure that's what I paid for. Had it not been perfect then Comet would have it marked as 'seconds, and would have charged me quite a bit less.
As it is, it arrived direct from the factory with this defect, and as I have said before, on a £100 cheapie off eBay I would probably put up with it, but not at 400 quid.
Add to this, unless Asus receives units back to their factory with these issues pointed out they will be unaware of the problem and have no incentive to tighten up their manufacturing process.
I don't know what is going on over in the US, but I do know they are far less accepting of poor service/goods than we are in the UK, and if these problems exist in units being shipped over there they will be flying back to Asus at a great rate of knots, and this is with the Us Transformer costing CONSIDERABLY less than it does over here.
If you have a good one, I am happy for you, and slightly envious of you. I wish I did.

On the blue boot screen or setting screen there is massive light bleeding on right and left side (about 2 inches wide). However, when there is an image on the screen it looks fine. Unfortunately I don't have a wireless connection at home so I haven't tried putting any movies or 'black' jpegs on the device for further testing; but will do so tomorrow. My hope is that when playing movies it looks fine and if so I won't worry about it. Screen has good fidelity; speakers seem decent and unit feels lighter than the acer/xoom. Also build doesn't seem that bad.
-
So far only immediate reactions are: Why didn't amazon put something in the shipping box like bubble wrap and what the @!#)(* no charging light? Even my $10 cell phone has a charging light.

I asked Asus phone support. They said there should be NO light bleed. I said a couple of times that mine is very slight, from the lower left corner, and he repeated that there shouldn't be any at all and that I should get a replacement.
I'm requesting a replacement anyway as my compass is broken, hopefully I can get one into my local Comet store so I can see for myself first.

A picture, as they say, paints a thousand words.
(and just to rub salt in the wound, discovered the gap along the side of the screen mentioned in another thread! 'Hello, is that Comet? I have something I need to discuss.....')

Light bleed here as well
Just wanted to chime in and say I have it too. At first I didn't notice it because I had just got it.. but after a while I found my eye being drawn down to the edges where there was light bleeding through. Its an unwelcome distraction and this unite will no doubt be exchanged for another one.

Auto adjusting works when you turn the screen off then back on.

i feel all of you. One time I bought a car and one of the tire pressures was off by the time I got home. I took the car back to the dealer several times til they got the tire pressures right on all four tires. Took a month to get it right. The nerve of these manufacturers.

No, this is more like buying a new car and your car doors or windows not shutting fully.

Screen sploches and dots

I'm having an interesting issue.
When looking at really dark images I can see sploches and streaks in the screen which don't move if I pan around the image.
To replicate open up an all black photo in gallery, let your eyes adjust for a second. Do you see extra dark regions that look like spatter and streaks?
I'm not sure if I can get a camera to capture it....

Do a screenshot, hold down power and then hit home button
Sent from my HTC One S

Taking a screen shot didn't capture anything. You can tell it's a hardware issue because when start to slide in the next photo the sploches stay there as the images move. Might go get another handset if this isn't happening to anyone else.

Maybe you can post the dark pic your looking at so we can see if we can see the same effect. I tryed looking at a black pic on my phone and I dident see anything unusual.

I had this same issue with my first One S, the unfortunate thing is once i saw them i knew where they were and couldn't unsee them, took it back to where i bought it and they swapped it. I also had light leak at the top and bottom edges of the glass on that same device, its just a build defect.
My new One S has no splotches or lines

This was a major issue on the Tmobile GS2, I have a pretty keen eye for it now. It shows on darker gray colors more then straight black and the One S I have now has this issue. It's a problem with Amoled displays.

So what's the verdict, do I return it or deal with it?

If you're in the time period then exchange it and see if new one is better. Can't hurt

White strokes/lights in the edges

Had to use my transformer in the sun today and all went well. After arrviging at home I restarted the device and I saw overblown white lighting on the right left and top bottom side. Although you can only really see it with a dark background this thing is really annoying, I didn't do anything wrong like leaving my transformer in the sun or stuff like that.
So is this software or display related? If its the later I am going to return it to Asus and asking for a new display, because otherwhise I really love this beauty almost replaced my casual everyday work notebook.

How big and bright is it? If you're seeing it only on dark backgrounds, it sounds like it's light leak; which is pretty common on these types of LCD panels. I think the spot has always been there and now you notice it. Being out in the sun had nothing to do with it.
While light leakage is considered common, we can replace the panel under warranty if it's severe enough.

Thank you, I have tried to make a screenshot but it just doesn't show the lights, so I am going to try it using my handycam tomorrow, will update this thread then and post it here.

Yeh take a photo with a camera. A screen shot will not be able to show the light leak since it's the actual panel that's affected and not what's on the display.

Uneven backlight/ colour tone shifting on bottom half of the screen

Just purchased a brand new Galaxy S6 32GB FLAT in white today. Right out of the box, especially on a white background, I noticed that the bottom half of the screen shifts into a more warmer tone. It's most visible on a white background, where i can actually see the transition between the two colour tones. Other colours are affected too, but not as noticeable. Please refer to the attached screenshots, (Ignore the diagonal lines running across the screen, caused by the camera artefact).
My question is, is it normal? Can you please check yours and provide feedback? Thanks in advance

I have the same

Its a common issue. But it shouldnt be like that. You should get a replacement

Dude this isnt severe. Ive seen enough amoled displays having worse tints and stripes. Yours is much better than them. If I was you, I wouldnt settle for this. Replace it or get a refund. I have severe ocd about my phone. I need it to be perfect. Luckily the S6 that I have has a very good display. A perfect one. Get a replacement asap. This isnt something normal.

Im ordering my 2nd replacemeny soon. My first one was yellowish and uneven like yours. My current one has a horrible pink tint. Try 3

Welcome to the club: http://forum.xda-developers.com/galaxy-s6/general/getting-replacement-s6-due-to-screen-t3074865

I took my phone back to the Samsung store and got it replaced by the manager there. The screen looked fine when i first looked at it in store, but soon after taking it home i realised that this second unit has a yellowish tint on the right side of the screen. Going back tomorrow for another replacement.... SIGH!!!!!

My third replacement from the Samsung Exp Store is.... a KEEPER! This unit has a much better even backlight and meets my expectation! After going through that trouble, i'm happy to say that I'm a a happy camper

Looks all right to me, but then again we all perceive things differently. My current unit is not perfect, there's still a green/blue tint to it, but it's tolerable. If you cannot tolerate it, then keep exchanging until you find one that you can tolerate with. Keep in mind though that you won't find a unit with 100% even colour hue; it's the limitation with AMOLED displays. All the best!

I have the same issue

I have the same, but much less severe than yours seem to be. I don't notice it at all with normal use, only super slightly on bright white screens. If it really looks like it does on the photo, I would get it replaced.

Light bars on black wallpaper
I have the following issue on black wallpapers.On top and bottom there is a lighter bar.This appears only after applying the wallpaper.Viewing them with Quickpick there are no bars.Same in Nova and TW after applying it.Tried attaching a screen but the bars are not captured.What could it be,a ROM issue,a low DPI?I have the DPI set to low.Also on brighter pics you can't see the bars ,after applying which makes sense.

White uniformity - Is this the jelly effect and is it normal?
I got a really good deal on a used Tab S6 from Amazon and I love the tablet but there is weird tinting thing happening on white screens.
When viewed slightly off-axis the tint goes blue.
Makes me nuts when reading NY TImes and edges of white screen are tinted blue.
The effect changes when viewed at different angles and seen without screen protector. It is tough to photograph but hopefully you can see what I see.
Ignore the moire in the middle of the first shot - that's a screen protector... Look at extreme edges of screen.
Thanks and pardon me if this has been answered before - I've searched and couldn't find this issue.
