Damn, doesnt sound good
Still, google did say that the tablets are still 'under testing' and should be getting a few more updates before released to us. Hopefully one of those will fix it

I'd be interested to know if any of the members here have encountered this issue?

I'd like some corroboration if anyone has it.
Edit: Corroboration and comments. Are any of you seeing it in daily use? Etc.

Probably just from the bad batch

Ha. This figures. I have a Prime and have had numerous display problem, along with many other Prime owners. Take a look in the Prime forums if you're interested. Asus uses crappy displays.

I'm sure if this was a big problem there would have been a lot more complaints by now.

Mine doesn't seem to have this issue, it does have a slight flicker though, but I'm hoping that will get sorted out with a newer build.

Did you test that image?

Well, I have to say I have never taken my prime, set the screen to max bright, left and image static on it for "several minutes" and then checked.
Seems like an odd thing to do in day to day use.

my prime display operates & looks fine. way too early to associate this with prime issues. I hope this nexus forum doesn't get influenced by negative assumption driven mentality and the consumer version of Nexus 7 isn't even released yet.
way to soon to jump the gun on a reported issue. I see I may need to create Positive Nexus 7 thread also...lmfao
lets not become divided in this forum like prime one. it was the ones whose primes worked fine vs. those with issues. SMH. it got ugly in there, especially in the beginning. I thought I would be escaping the madness by this being a Nexus driven forum/device.

This is NOT a problem, ghosting is a common occurrence for all IPS displays. Just a quirk they have, don't leave the display on full brightness on a static image for 5min and you will be fine.

Hi,
my Nexus 7 has this problem.
I don't think it's a common "ghost IPS problem", because I get it also if I leave the tablet for 5 minuts in stand by (so screen off). When I power it on the screen is white and it takes about 1 minute to get normal.

The Ars Technica review suggests that the ghosting issue gets better over time. Fingers crossed.

My G2x has an IPS display and doesn't ghost. This does however remind me of people going Max brightness in a dark room to test for "screen leak" and complaining when they find it under such drastic conditions. Yes, the article above does say even under automatic brightness but the fact that they tested with Max brightness made me chuckle.
I don't know... just not really worried about it. If it seriously ghosts really bad I'll return it, and if it doesn't I'll keep it.
Definitely jumping the gun on this one. No one has even seen a production model afaik, so just chill until you actually get yours.
Thanks OP for bringing the issue to our attention though.

I really hope. My Nexus 7 has been opened for the first time couple hours ago, but for now the problem is really annoying.

Hmmmm interesting thread. Guess we will know within the weeks to come!!

My Prime had serious screen bleeding in a dark room, no wonder what the brightness was, so dont write off all the people who experienced screen bleed..That being said, and like others have mentioned, it is way too early to lump the nexus7 in with the TFP...although I did have my reservations about the nexus7 because of Asus's track record with tablets

got my 16G Nexus 7 last night and experienced the exact same problem as yours, the washout took more than 5 mins to disappear

Ghosting, washout, flicker
I got my 16GB yesterday and have all three problems. After I close Chrome, for example, I can still see (faintly, but legibly) my tabs, the URL bar, the URL even, etc.
I have a slight flickering problem.
I definitely have a washout problem - and it changes, too. Sometimes it's severe, sometimes not so bad.
I'm going to give it another day or two and if it hasn't resolved itself I will probably return it for another one.

The things you didn't know about your Nexus 5 yet thread.

Okay guys,
I haven't posted anything on XDA for a long time.
But my stupidity has led me to posting once again.
My Nexus 5 was performing great. Loved it! No defects whatsoever.
In these days it seems like you need to be a bit lucky when buying tech.
It happens quite a lot that one buys a device, only to find that something or other is wrong with it.
With this thought still in the back of my mind, I noticed my N5 behaving strangely a couple of days ago.
And of course thought to myself: "Yep, there we go. What will it be this time."
See, the thing was that sometimes when I turned the screen off and put the phone down, it would turn the screen on again.
"That's odd." I thought to myself. And the weird thing was, it wasn't consistent.
Sometimes it would, sometimes it wouldn't.
Very odd indeed. To top it off sometimes it would have the actually quite cool feature of turning the screen on when I picked it up.
Just before I wrote this I was browsing the web, annoyed about my faulty Nexus, when for a short pause I looked at my desk.
Was I really that stupid? Could it be?
My N5 was laying on my N7... The N7 was nicely protected by a case...
This case... Has a magnet in it...
Apparently the N5 has an auto on off function for flip covers. My god did I feel stupid.
This was one of the biggest face palm's of my tech life and I couldn't resist to share.
Post your recent discoveries!:good:
Cheers,
Daan

There isn't much about the N5 that surprised me, but here goes :
- you can take a picture using the volume buttons (I know it's from 4.3, but I often forget that it works!)
- compatible flip covers can wake up the phone
- you can scrub back and forth through a song on the lock screen (not just skipping tracks)
- ART vs Dalvik
I think that's it.

multi color led is a big one for me... was using light flow but wasn't seeing different colors... tapped on the led a few times and it 're seated'...

You can use your Nexus 5 for hammering nails*
*Not recommended for hammering nails.

Tried to use as a vibrator on my wife, but the vibration is nothing like my old n4.

Active Notifications lighting all pixels?

strange quirk with active notifications.
1) notifications light up using select few pixels (GOOD)
2) notifications fade out and go away completely (GOOD)
3) all pixels light up very dim for a second (KINDA ODD)
You have to have the lights off in your room for you to notice it really.
Check it out...

Mine doesn't do that in a pitch black room.

its super super dim and hard to catch if u dont OCD over things like i do.. lol

call motorola, they might be able to get your a replacement, if you havent rooted and unlocked bootloader

oh man, seriously nobody else has this going on? its such a small bug and seems fixable.. i dont wanna send back my motooo!
gonna try n reset the phone to see what happens.. my expectations are near nil though.. anyone else with this strange issue?

Just tried in a pitch black room. Saw nothing after the active display time faded out.

The whole screen flickers gray right? I'm on a Rogers X. Mine does that.

Just for giggles, I checked out my phone and two coworkers phones and none of them do it. Two AT&T, one Verizon.

Yeah, I don't think that's normal. The whole reason Active Notifications doesn't annihilate your battery life is because only the pixels that need power, get power. That's how AMOLED works. You can turn off each individual pixel. Which is why you don't see something like Active Notifications on phones with an IPS panel such as the Nexus 5. IPS works by lighting a giant backlight, and the pixels act something like shutters, opening and closing as needed. Of course it's more technical than that, but in layman's terms, that's how you can think of it.
So yeah. Something's up. Those pixels should not be lighting up on an AMOLED display. If it were an IPS, that would be normal.

Two Rogers phones here, neither do that.(I am running 4.4 though)

My VZW MM doesn't do that. Seems strage, as it's a big selling point for the phone that it only lights the pixels you need.

i have the same problem, im on 4.2.2, i will take it to motorola

thanks for the explanation! cant wait for OLEDs to be ubiquitous.. wonder what comes after OLED, or is it the final frontier for active matrix

Since its a problem that only I would notice, and only in the darkest of rooms, I Dont want to go thru the hassle of explaining to the poor guys at the Rogers store why I want to exchange the phone. I'm wondering whether it may be a software related thing... What's the best way to reset the software besides deleting all data.. Is there a way to get down deeper and scrub it clean?

Well, it's most likely just a software bug in the Rogers 4.2 rom. As the others who are not on Rogers do not have this issue, your best bet is probably to upgrade to the T-Mobile 4.4 ROM, which is what I'm running (I'm also with Rogers).
EDIT: Just noticed someone had said that they had Rogers phones that didn't have the issue... I say proceed with caution. You can try reflashing the Rogers stock firmware from the internet, see if that clears it up?

I've had 4 Moto X's. They all did this. It doesn't impact battery enough for me to worry about it. It may be the backlight or something though I admit I know very little about how SAMOLED works.

I think is happening is that there's some code in there that's telling the transistors to discharge throughout the matrix instead (which explains why the whole screen is dim for a second) which helps with reducing the amount of wear on individual parts of the screen (the notification icons itself). If someone can compare the ActiveNotification between 4.2.2 and 4.4, that would be nice.

Moto display color issues?

Has anyone else noticed a subtle color change, almost like a flickering when when unlocking the moto display? It is something fast but it does happen and it is getting annoying.

Yes, and it's so miniscule you wouldn't notice unless someone pointed it out.
My opinion: get over it.

I didn't notice such a thing. Not even when you point it out.

Ok i updated moto display, now I see it as well. The normal lock screen appears for a millisecond. The fact that I didn't notice it before the update proves that it wasn't there before and should be fixed easily by Motorola.
For now I deactivated the lockscreen, I never really used it.

[Q] Want to buy nexus 6, are there still screen issues persisting?

Please help. I am planning to buy nexus 6. I have read a lot about nexus 6 display issues like burn in issues , uneven color, grey lines and lower half of screen freezing. Some say these are present in all devices to variable extent and in most exist in mild form.
Should i get nexus 6 ? does these screen issues still exist?
Else i will buy Galaxy s6

I've had mine since November 2014 and I have none of those issues.

Smooth sailing here
I keep it adaptive 66% brightness and its all good no burn-in that I can see I have noticed some specific apps like chrome cause a weird freeze on the right screen half happens maybe once a month with no pattern (a quick screen off/on fixes it could possibly be a custom kernel thing). Only other thing I'd say is the screen has a very warm color palette by default, I use code blue with kcal 237, 235, 255 to make a cooler feel, there's a thread about it somewhere. I've had mine since February.

The Galaxy S6 has lots more software issues then the N6 atm and besides that i have never personaly had this screen issue. The N6 is a great phone especialy now it is beeing discounted here and there (US and UK).

Been rocking N6 for last 1 month and i am loving it. No issues at all. Like u i was also very concerned to put into huge sum of money into N6 purchase after reading soooooo many discouraging videos and reviews and comments.
But i am using it as my daily driver for like 1 month now and i haven't seen any issue related to screen, battery, or even software. 5.1.1 is very stable.
I keep the adaptive brightness on and brightness level at 50% and i get 4 - 4.5 hours SOT with everything on...including google now, location history, location reporting high accuracy.
No screen burn, no battery swelling, no battery life issues, no screen freezes, bt yes i'll admit the screen colour is more on a warmer side.

I got a Nexus 6 from Google Play and a friend got one from Motorola in June 2015. Both have screen issues, one have vertical banding noticeable on gray or dark backgrounds, the other has a yellow tint and very uneven backlighting. I'm not sure if most have these issues and simply aren't bothered or what. Not sure what to do at this point.

Flawless here

No issues with mine ....

mine works fine never had any of the issues above

No issues for me.

There's no backlighting.

What I meant to say is that strips of the screen are brighter or darker than the rest of the screen and it looks blotchy. If I hadn't viewed a solid gray screen, I might not have noticed but this doesn't make me happy, especially knowing that Android M has a dark theme with lots of grays.

I've had my white 64gb from Motorola since March. Had it replaced once already for the screen tearing issue when running a custom dpi. The replacement I got a month ago does the same. Will be calling again soon

I got a nexus 6 at ATT through the next program a couple months ago. It had banding on the right side of the screen right out of the box. It was pretty discouraging. I took it back and got it swapped for another unit and honestly couldn't be happier. The n6 is an amazing phone.

Screen tearing or half black?
Issues relating to custom DPI happen on them all.

I received mine on 6/18, no issues other than a pink hue at low brightness (with adaptive brightness turned on) which seems to be software based.

Half black, and half freeze, which I've seen be referred to as screen tearing in just about all the posts I could find on it. Funny thing is on every kernel or ROM thread ice asked about it I've been told it does not happen on all of them. Seems many have had their phones replaced and had no issues in the replacement and that has led to people believing it's a hardware issue. Only other explanation I had seen was something about Franco saying it's a possible display driver issue. Sucks that I can't use Franco kernel at AOL because it becomes horrible

The tearing, which by that I mean freezing definitely seems to be a graphics card issue. The half-black if you change the DPI and rotate clockwise so buttons are on the bottom, afaik happens to them all. I think this is related to the GPU to, though I don';t think that is hardware issue. The tearing issue seems to manifest more when the device is warm/hot

The tearing is a graphics card software or hardware issue? I love this phone, but it's getting very frustrating. Especially since my RMA prices with Motorola turned out to be a series of clusterf*cks.
I'm running Chroma right now and with the included Franco it's unusable in both my phones at a lower dpi. Half screen freezes left and right within seconds of starting up. The reasons I initially believed it was software was that it only seems to happen in certain apps. Specifically ones that required a lot of scrolling, like XDA, Facebook, and chrome. But no one else in the thread seems to have the issue
The half black screen I figured had to be software because the soft buttons are still on the screen.
I just wish there was a solid answer so I could stop guessing

I've never had the tearing issue and not everyone has that one. The guys who have had an RMA have generally said that it had stopped the issue happening. Im not sure that has any link to DPI either. My suspician based on not really any evidence at all is that it is hardware related, since some have it and some do not.
The half black is definitely linked to DPI and there is no fix to that that I am aware. I just turn that rotation mode off so I can only go anti-clockwise.

The weird thing with me with the tearing is it only happens in certain situations and has been consistent across both devices I had. Certain kernels I get it, other ones I do not. Franco has been unusable for me on both. It has only happened at lower dpi. Never on stock. Send to be less frequent with interactive governors than ondemand or conservative
