[Q] Strange marks beneath the screen

I’ve a strange problem with the screen of my Note, I noticed this when switching off the phone in a complete dark room. The screen turns dark grey for a split second before switching off, this is when I noticed some strange black marks beneath the screen.
I made a jpeg to replicate this problem (1st attachment), along with a screen capture of the marks (2nd attachment). Can somebody please download the picture and check to see if there are any marks on their phone?
You need to be in a complete dark room for this to work, it helps if you turn the screen brightness to 100% and allow a bit of time for your eyes to adjust to the dark.
I also added roughly what the marks look like.
Many thanks
P.S. this does not affect the screen in normal use.

I have noticed that too....
Edit: forgot to mention that it does not affect usage in anyway

Why.....
SH!T, not this crap again. The Galaxy S2 has this at a greater extent, but I was LEAST EXPECTING this on the Note, especially since they JUST starting manufacturing this model. I don't even think the demand is as high as the S2. I'm having mixed thoughts now. Those marks are NOT normal.

hi...is your phone UK or EU version?

This is the biggest manufacturing defect of the season! Go to the Samsung Herculus (T-Mobile S2) Forum and you have over 500 users observing the same exact problem! Samsung is carelessly sealing the back of the AMOLED display panel, therefore you will see lines and blotches everywhere. This is absurd!

I guess it could be a problem, but to be honest with you, I don't have any interest in trying this.
Go to a completely dark room and turn the screen to 100% and look for defects? Uhh, what?
When I'm in a very dark room, I find 3% quite comfortable, thank you. (10% brightness * screenfilter (30%)

Hmmm.... so something that you can only see when you are switching the phone off in a completely dark room is "the biggest manufacturing defect of the season"???
I understand that when you drop hundreds of £s/$s/€s on something, you want it to be perfect, but something that can only be seen for a split second as you turn the phone off in very specific circumstances, scarcely warrants such a title in my opinion!
I can certainly think of worse - lightbleed on Asus Transformer, or Newtons rings/oil click on the Galaxy Tab 10.1 for example, which (if present) can be seen during use.

I agree with foxmeister. Why try and find a fault when there's really no fault there!
So you've got dots on your screen when in a completely dark room, with screen set at 100%, that lasts for a second or two......so what! Don't sit and stare at your phone in the dark is the answer. Then the problem will go away.
Jeeez, some people are never satisfied or happy.

Thanks for the feedbacks, I have the EU version from amazon.de.
There is definitely a fault with either the screen or how it was put together, otherwise I'll not be able to notice it. Those marks does not show up on my Galaxy Tab 10.1, the original Tab or any my pervious mobile devices as far as I can remember.
I did note this don't affect the screen in normal use. Also the 100% brightness suggestion is to make the problem easier to spot, I normally have the screen at 5% in the dark, and we have no control over the brightness when the phone is switching off (when I noticed the marks).
I started this thread to find out what is the course of this problem and how widespread it is before deciding if I should send it back to Germany for a replacement/refund.
BTW, under EU consumer law, we have 21 days to return the device either for a refund or replacement from the seller, after that we might have to send the phone for repair.

Sounds like there is a manufacture defects with the EU version?!

Head over to the International Galaxy S2 and Galaxy S2 (T-Mobile) Forums and the answers behold. Hundreds of comments stating the same exact issue. I'm just surprised how this slipped into the SAMOLED HD display. I don't recall the original Galaxy S (which also had a Pentile Matrix) having such an issue, or did it?

I have a Galaxy S II, and regularly frequent those the international forum, and I've not seen this come up as an issue (though I don't disbelieve you that it probably does somewhere). I looked in the TMo US Galaxy S II specific forum and I did find such a thread, but I was unwillingly to pour through 50+ pages to see the final outcome as it was filled with people who have the issue, don't have the issue, or have the issue but don't care.
I've not noticed this issue with either my Note or my Galaxy S II, and I'm not going to go look for it in artificial environments that I'd typically never be using my device in.
"If a tree falls in a forest and no one is around to hear it, does it make a sound?"​
According to the OP, on the Note, this only appears for a brief moment whilst the phone is being switched off in pretty much total darkness, so my point is - does it really matter?

Dave

Well, many EU owners are already reporting black spots on their Note!

I was lying in bed last night and saw what you are talking about. I think. I has used my phone heavily for the last week and didn't notice anything else.
So I suspect we all have it but uhhhhh whatever.

See this link for another photo of the problem:
http://forum.xda-developers.com/showthread.php?t=1337499
The photo is taken with a small Canon camera, with ISO = 200, and a 15 seconds of exposure time.

Post removed. I started a new thread.

The Note is going back to Amazon. I was able to see the some of the black marks against black border when watching film in the dark last night with the screen brightness of 5%.
I was going to keep it before it started to affect my normal use, lets hope the replacement has less or no marks.

[Q] Excessive banding/vertical lines in photos.

Hi, just recieved my GSM developer edition Moto X yesterday and I've been having trouble with severe artifacts in low light photos. Is this amount of banding/lines normal for the moto x? I'm wondering if it's a sensor issue and it's worth trying to exchange my phone. I have not noticed this level of artifacts in any low light sample photos.
Even if I cover the camera sensor it shows red lines where it should be black. See the samples below.
It's most noticeable in low light but the lines seem to be always present. In the camera app the lines shimmer on the screen and flicker from red/purple to blue in dark areas. I tried the camera FX app with anti-flicker set to 60hz but it didn't make much of a difference.
I have rooted the phone but would that cause this? Thanks for any advice!

I think it is normal, otherwise all three moto x's I have used have been defective. I hope to see a software fix for this.

Maybe different versions have slightly different internals. I have the Rogers version and mine doesn't have those lines /bands.

I am willing to bet that you just haven't noticed them yet. Try it on a low contrast object like a light colored counter, under fluorescent lighting.
These are the types of situations where it is most easily reproduced.

It only happens on the front camera for me.

I think it's related to certain fluorescent lighting. I've been testing the camera around work today under various lighting conditions and the lines are nowhere near as severe around LED and HID lamps. CFL bulbs, seem to cause the line artifacts the most while standard tube fluorescent lights don't seem to have as much of an effect. I'll play around with it some more.

The camera appears to have a very slow refresh rate, as a result you can see it beating with the 60hz from certain light sources. Every Rogers Moto X I have seen does it so I am sure it's a problem with all Moto X's. Could be a hardware limitation, if it can however be fixed in software I hope Motorola is working in a fix.

I believe that it's software as I have seen the same banding in my Nexus 4, but only with some settings applied with FV5 (not the stock camera app).

The HTC one had a similar issue and it seems that using HDR fixed it. Could someone with the Moto x try using HDR in the same lighting conditions and see whether or not it still bands?

I've tried using hdr and photos were still terrible.
I'm using camera zoom fx And with it I'm not having stripes. The problem is it only takes 5 mp photos and obviously loosing the twist to activate the camera thing.
Please, report this issue on Motorola's website. We have to make pressure in order to have a fix.

I played around with a couple of moto X's on display at best buy and compared the camera live view side by side to mine. Neither of the display models, both AT&T branded, had the banding/lines flashing across the screen problem while my phone, a dev edition, did display the banding issue. I didn't think to check what version the display models were running but mine does it on both 4.2.2 and 4.4.
Frustrating... I'm going to contact motorola support about a replacement. I can't get a single decent photo out of mine. Also any video I take is covered in dancing red/blue lines.
Edit: Also HDR mode makes the problem worse if anything, hard to tell.

Interesting, I played with two at the local Verizon store and they both did it.

Just saying... These are phone cameras.... If guys need to take real low light pics with no flash... Perhaps you need a real camera?
Every pic I've taken... Outdoors, inside day time... No flash... And inside night or day with flash... And haven't seen anything wrong. The pics all blow my S2 camera away.
I understand being more picky about pic quality than maybe I am.... But that's what real cameras are for. Phone cameras suck even compared to the cheapest real cameras.
just saying. Maybe my phone doesn't have the issue... Or at least I haven't done any pic taking in the right conditions yet.
But to say the moto x camera is crap.... Is ridiculous. It's just fine..... For a phone.

I am aware it's just a phone camera however I do not expect there to be lines all over the images. In live view on the camera of your Moto X does the image flash between red and purple hues a lot? I'm trying to determine if mine has a defect. Any pictures I take, especially in dark conditions, have these lines all over them as in the example below. Do you see similar from your Moto X?

Specifically, it is most reproducible in artificial light with lots of white or, in general, low contrast subjects (a piece of paper, a counter, top of a washing machine). I have not been able, under any circumstances, to reproduce it in natural light or DC light sources (no flicker).
I spent an hour this morning with a tier 2 moto tech to try and get him to reproduce it. He couldn't, and I have a theory as to why, but won't be able to test it until nightfall. Stay tuned... I WILL pin this down and then we can start a discussion in Moto's forums and try and get their attention.

Having the same issue. The excuse that this is a "camera phone" is ridiculous. I've had plenty of other "camera phones" that work without issue.
The lines are clearly visible in the attached pic. I have to wait a few seconds for the lines to go away to snap a picture.
This phone may be going back.

That second pic I posted in the post above with red lines on the bottom was taken in my car at night with only DC light sources around. I've got a few video clip with those lines dancing all over the place under different lighting conditions, I'll post them when I can.
I believe there are two separate issues on my Moto X. One being the alternating orange/blue lines that show up under fluorescent lighting which most Moto X's seem to have a problem with and the second being these noise lines throughout the entire image under any lighting condition besides outdoor sunlight that seems to be a less common issue.
Interested to find out what your testing uncovers.

Flash or no flash, easiest to see the lines in the poor lighting but they show up around the short edges of medium lit shots and also show up in video. They disappear in sunlit photos. I'm going to take a video of the liveview on my Moto X to better illustrate what I'm seeing. I'll post better examples when I get home. Interested to see what your photos look like.

I'm on the phone with tech support. They had me download another camera app (Camera MX), it exhibit the exact same issues
They want to do an exchange.

[Q] Static lines & bands on screen. Yes, please help.

Guys,
I've tried 3 different phones from Flipkart. The first one had the famous yellow tint issue which was down to a minimum in the next 2 devices that i tried so I guess it all depends on luck. But as luck would have it or OCD , I had new issues with them.
Both the replacement devices that I have tried so far have these 2 issues below:
1. Weird horizontal bands visible across the screen on light backgrounds (white/grey) most prominent on low brightness. They really annoy you when scrolling through your Twitter feed or any apps with a white background (Most on Lollipop!)
Best way to check these are in the default android dialogs of WiFi password or language choice.
2. I see static lines horizontal lines on the screen everytime the screen is touched and they disappear after 2 seconds of the touch. Again easiest way to check this would be to open the gallery and pull in the hamburger menu from the left. When touched to pull, mine shows prominent static/disturbance sort of ripples.
Can you guys check and tell me if these are common issues since both my replacement devices have these & I am really not upto trying another device after all the hassle.
Thanks.

I'll see the horizontal lines as well on light backgrounds, I just assumed it's a side affect of amoled.

Perhaps the lcd is defective?

Can confirm that my screen also has the issue #1. I always thought it was probably a large AMOLED screen issue. Never faced issue #2 though. I also got mine from flipkart.

Issue 1 is what bothers me the most. Scrolling on white backgrounds is annoying, you feel these bands are not moving & look prominent.
Even more worried since everything's going white in Lollipop.

Though I dont have a similar problem but I am pretty annoyed with my purchase. My first device was replaced since it developed screen-burn within few days of usage. Surprisingly, the second device has also developed screen-burn after 10 days of usage and the nav keys are permanently embossed on the screen which can be clearly seen on grey backgrounds.
The strangest part I found about both the devices was they were turned on right out of the box One click to the power button and the phone was already in the setup mode asking to select a language. White color reproduction is way off on this device and looks pale yellow instead of white I somehow feel that I should have stuck with my Nexus 5 instead of falling for this. At-least for now, I'm done with AMOLED's

So have you returned the Moto X?
Motorola seems to have major QC issues. Distorted speaker, yellow tint, weird lines and burn-in.
It's a great phone but the screen has major issues. I am on the fence now about trying a 4th replacement device but worried it'll have more issue.

They are not there all the time. Only on light backgrounds. Best way I can describe it is if you've ever seen a plasma TV that gets horizontal purplish lines going vertically from a color source on an all white background. The horizontal lines on my phone follow the dark letters/images as I scroll up and down.
And I actually RMA'd the phone today because of it.

I had the dark horizontal bands on my replacement device they sent for the back separating. They were very prominent on light backgrounds and very distracting. I chose to keep my original device because the screen is perfect on it. I didn't want to take chances with replacements beyond that. I took pictures and notified Motorola of the issue.

Oh, I've been pretty unlucky so far in that case, haven't got a screen without these bands. Well atleast there is hope.
But there's the same concern, will the replacement be better or worse than the one you have. In India, we have to hand over the device at the same time, so cannot compare the two devices.

So, I have not heard a thing from moto about my RMA label. On the site it said I'd get an email in 4 business hours, well all day and nothing. I'll have to call tomorrow I guess.

Well... Moto has no record of my RMA and I lost the RMA number because I took a screen shot and the pic didn't sync before I blew my current phone clean. They tried my IMEI and SN and contact info, it's like it never happened. They said they could try looking at the RMA number, but, I don't have it. No confirmation email either at the time of entering it.
So, I'm not going to bother again right now as others have said the replacements do the same. I got the two year warranty, so if the screen does eventually go dead, oh well.
What I will warn others of, is to WRITE DOWN the RMA number!

My first device was perfect - but I returned due to a scratch on the wood back. Second device is half yellow, half white tint with horizontal lines. It's like playing the lottery because the qc is still awful on amoled. I wouldn't mind if the full screen was yellow even but the half and half is terrible. Yellow can be fixed with color tweaks and wasn't all that bothersome anyway.

I have one dark line across the screen. I chatted in with them and I have to call them and ask for the REST department since mine was a custom one.

I've seen this once or twice, it appears to be when the phone is on 2G and data is on 900Mhz LTE.
But I can't say it's very visible, I can barely make out a pixel or two vibrating in very specific settings.
What's your model number?
I have the XT1092.

Yep even I have the XT1092. I am trying to live with it for now. Have till Dec 10th to decide whether I want to risk another device.
The bands across the screen bother a lot more than the static lines. Hope Lollipop comes soon so I can make a final decision.

You should try to capture it on a video clip, my lines are just barely visible in low light.
Film it and send it back for warranty with that video as proof. And post it here, I'm curious to what it looks like.
I'm pretty sure it's the LTE radio, because I can just barely make out the noise in my computer speakers when it's pinging the GSM tower.
Much like when old phones use 2G mode, but at a way faster rate and not as loud.
You might have gotten phones from a batch where they forgot EMI shielding or something like that.

Grainy screen?

I received my Moto X about 3 weeks ago, but noticed on white/light backgrounds, the screen appeared grainy. So last week I called Motorola to ask for an exchange, which they did. I received the new Moto X today, but it's suffering from the same grainy screen as my other one. Does anyone else have this issue with their X? My old Note 2 did not suffer from this, and they are both AMOLED screens.
Also interesting to note, the first Moto X was assembled in the US and the second one in China, so I assume the screens came from two different batches.

Yes, even I had this issue but after comparing with others I realised it's normal. They grainy are only visible if you really pay attention and scroll slowly. Eg. Gmail app.
I've learn to live it though.
Moto X 2014

I never thought to explain it as "grainy", but yes, I have it too. I almost RMAed it for that as it sometimes looked like lines going across the screen when scrolling. Actually, I did RMA it, but moto couldn't find it in there system for a week. I finally got the email, but haven't called them back yet.

same here... its more like texture, and you do see the lines when scrolling.

Is it worth trying to RMA it again until I get one with a good screen? I would certainly consider this a flaw, especially when spending $500 on a phone. I truly do enjoy the phone otherwise.

It's the pentile screen nothing wrong with it. I have the grainy screen too.

Grainy is normal. Horizontal or vertical lines are not - also tint issues are not normal. My screen is 50-60% yellow tinted and the remainder white, not normal - rma'ed it and awaiting my replacement.

Thanks for the help everyone. I am also noticing faint horizontal lines on both Moto X's on white/light backgrounds, but the replacement from China seems to have more than the original, and has a red tint to it. I'll be calling Motorola in the morning.

Bad qc on amoled. It's a gamble...

Yes. You can another thread that I created: http://forum.xda-developers.com/moto-x-2014/help/static-lines-bands-screen-yes-please-t2935981
Currently I am just using the device since there's absolutely no guarantee the next one would be any better given that these issue are common. The QC is really bad.

Moto X 2014 LCD WaterMark

My friend have just bought a Moto X 2014 At&t variant with Lollipop 5.1 installed in it. I noticed a weird thing. On its display, it has water mark of Motorola logo and and some other Text and Icons. A screen shot is also attached. I have searched over internet and unable to find the solution.
Any body know why is that so as another friend told me that it is a sample unit and its display (Panel) has these watermarkings.

Yes, that's probably screen burn-in. It's a very common problem for oleds. There's no solution, it's a problem with how these screens work.
If it's a new phone, I'd suggest he returned it.
