Screen Goes Crazy

I've had my Note for under a month now. I've been ever so careful with it. My heart skipped a beat when one day, all of a sudden, the screen just went mad!
I scoured the Web but couldn't find any other instance of this but the other day, in another thread, a few people have said that they've experienced the same problems. It's happened to my friends phone as well. I thought both of us were sold defective pieces to be honest but it looks like a global issue.
This is not just a case of screen flicker and screen changing colours on a white background. It goes haywire! Almost like the old television sets with their rainbow effect.
This has happened pre and post ICS; so it's definitely not a software issue. It has to be a hardware defect.
When I tried taking a screen shot of it, it just took a screen shot of the app I was using before the madness began.
It happened again last night. This time, fortunately or unfortunately, the screen stayed that way till I hit the power button. I had enough time to take a photo of it using a friends phone. Check it out :

It happens to me in some custom roms...
Its not a problem...
But it does give a heart attack

Same thing happened with me thrice. I think it start after ics upgrade

Its about some live wallpapers. Same thing happened with me with blue sea lwp after upgraded to ics.

I have this sometimes too, but I don't use live wallpapers so doubt if this has anything to do with it.

+1 I don't use live wallpapers either. Phone's not rooted either. It's probably an issue with the graphics chip. And it seems to be a global issue and not limited to any region as such.

It's happened on my phone before and after upgrading to ICS. So I doubt that's the issue.

It's also happened to me once,
not more than 24 hours after I bought it.

Thanks you reported.. I was not able to report since the screen got fine in few seconds. Didn't experienced it since..look likes hardware issue to me as well.. I hope samsung pay some attention here..

I sure hope you're right because the same thing happened to my laptop once. The screen started flickering this way occasionally and it the frequency increased. In the end, I was told that the chip and the screen needed to be changed. Luckily it was still under warranty at that point.
Just hoping the same thing doesn't happen to this AFTER the warranty lapses!

never experienced this.. i used ICS for 2 days, no sign of this issue back then.. and now im back to GB...
is this what they call pixel salad?

flicker or pixel salad, whataever you name, mostly happens when you end the call or call disconnection...the same happened to me and gone through the logcat and reproduced the same once again..

Dude. I was searching for this.. this happens for me.. OFTEN !! more than 15 times already i think. I think it started like this since having ICS. I had my first week on GB and have no such issue.. probably screen reset or what ?

Here too!
With my note it happened a few times.
I am currently running Rocket V7:crying:

funny i have never experienced this before... i've had my note for almost 3 months now
have upgraded to official ICS then root then went back to GB root..
just wondering for those of you who experienced this sort of pixelation, where did you get your note from?? mine was from the the telco when i renewed my contract and seems to me that it is more likely a defective unit..

Honestly, I thought my friend and I were sold defective pieces here but as I mentioned earlier, from the kind of response this thread is getting, it's definitely a global issue.
My unit was manufactured in Vietnam. Bought it at a store here in India. It's probably a case of a batch of defective units. Samsung needs to take stock of this. With their over zealous selling spree, it wouldn't surprise me if someone at the quality testing team was made to look the other way. Conspiracy theory maybe but who knows eh?

Mine came perfect.

The left side of my screen near the center makes a strange noise when I press down on it, almost like adhesive lifting.

This thread title has defects
No I'm sorry. I don't believe I have any dead pixels. Mind you, I didn't search for long. What freaked me out however was that I never got the USB drivers from the SDK. I'm good now though, rooted and runnin'.

100% ok here sexy n sleek

The few bits of information about people having screens coming loose has me all paranoid. Mine makes a slight noise if the push on the lower right side of the device. But close examination makes it appear not to be the screen but the rear cover has a tiny bit of play (assume it is a slightly less than ideal retainer clip). I don't expect it to be an issue but if it does turn into one but the time I probably need to RMA it they should be further into the production cycle and hopefully past small issue like that.

There's already a thread like this

I'm not sure I would call one dead pixel "very minor". Could absolutely ruin things depending on where it is.

Keep in mind, I am simultaneously knocking on a huge piece of wood as I type this, but my Nexus that I purchase at Gamestop is brilliant. No issues at all to speak of. Hope it stays that way and that all of you who got defective units get them replaced soon. Cheers.

This is what I'm afraid of ... had the first transformer and that device was just rubbish .
What makes me thinking is that all the issues I had on transformer are showing up with nexus .
1. Loose screen (in transformer at first no problem after a week I could feel it being loose when grabbed . After 3 weeks screen collapsed and from the top of the edge to the screen surface there was like 2-3mm difference
2. Light bleeds ... had it all over the screen. That was an IPS screen.
3. Screen not stuck properly top right corner . When looked at the screen under about 160 degrees (pretty much looking at the screen when its flat) the actual screen was off by 3-4 mm from the main glass and could see the light coming through
4. Dead pixel. One but that's it .
And that was just one single device ... makes me wonder how Asus build this one when I read all the comments

Yep sorry to confirm, but I have the "loose screen issue" with my Nexus 7.
It's a device from Google I/O, so it could be that this this batch was put together in a hurry, and that caused the defect, but it's still a bummer, that it's not even a month old, and this happens. There's no way of returning it, because I'm in the EU...
Oh yeah, it's one of the few ones with a white back. The white is rubbing off where it sits on the table and where you hold it with your hand. The base black is slowly emerging.
I hope the ones people actually buy will be better manufactured...

Different issue but just as irritating

Just got my third n7. I've had a c60 model and a c70 model both with the screen lift issue. Finally got a replacement to the replacement today and was delighted to see no problems...until I turned it on.
Immediately the screen looked dimmer.
I've now done a side by side comparison, checking whether it is the auto light sensor but its dimmer on all settings.
Has anyone else noticed this? Is it a result of different screens they are using or have I just got another duff model?
I've attached a picture showing both on the lowest light setting so hopefully you can see I'm not just being paranoid.

Man that sucks looks like you might have to replace it again...
I just went thru same thing except my C6 screen was good, battery was bad. 2nd one was C7 and that had the lift, I just exchanged it today (got mine at Gamestop) for another C7 which seems good so far.

I was being a bit stupid actually because I had a thought that the c70 thing meant they were using different screens now, but just after I posted I realised that both those in the picture are c70s.
I suppose this means that it is a genuine fault.
Perhaps I'm being really unlucky but I think I might get a refund from google and go buy it from a proper shop where I can have a look before buying

It's not uncommon for a manufacturer to use different panels. Just do a search on the HTC sensation having different panels, also the HTC MyTouch 4G, and I believe the Xoom when it first came out had panels from two different manufacturers

That's more worrying. That might mean its pot luck whether people get a good one or not. You would think that Google/Asus would be aiming for consistency.
Its a shame really because this is a cracking device if only I could get a decent one. This is also the first one I've had where the power button and volume buttons are nice and clicky!

Look on the box. They are talking about the first few characters of the SSN.

I just ran through my towns stock... [email protected] Meyer, [email protected], [email protected] all 7 had screen lift.. c70,c60 didn't seem to matter.. I never even turned em on, just had them open em while I was in the store.. huge bummer. Also waiting for refund to clear on the preorder I had.. that's 0-8!! Can I hate Asus now?
Sent from my ADR6425LVW using xda premium

Yes I had this!. Believe it or not I believe it's the brighter one that is defective. I've had 4 different nexus 7s now, and only one of them was significantly brighter than all the rest, even on lowest setting. At first I thought it was better, till I tried reading in the dark and found it was super uncomfortable. I installed lux, which helped dim it, but since it's a filter it made my eyes hurt having it, I still don't know why. On top of that, I noticed it had light bleed on the left side.
Somewhere on these forums I posted a picture of the bright one next to one of the other ones, just like you did, I will try to find the pic and come back here and post it.
I just got my replacement for the ultra bright one, and it is dimmer on lowest setting just like the others, but based on what I've seen this is how it should be. I think I am finally done with the exchange game, this one has a slightly raised left screen, but no squishyness or sponginess, no light bleed or dead pixels, and not much flickering even at lowest brightness on Google maps. I'm keeping this one

OK, maybe its not as simple as I first thought then. Although I would say that my overwhelming impression of this new one is that it is too dim and I've never thought that from looking at my previous ones or ones that friends have. Certainly my previous ones are not painful to use in the dark.
Its difficult to say without lining them all up and comparing but there is a possibility here that you had a defective model that was too bright, I have a defective model that is too dim and all the others are just right - the goldilocks models

and this is exactly what i imagined happening as soon as i heard asus was making the tablet, sigh, i still bought one, and i will exchange it when the screen bothers me enough, but I am afraid of the result of going through the same level of nightmare

True enough. I've got an original transformer which I had 4 attempts to get a fully working, non light bleeding, non creaking, keyboard holding charge, speakers working model. I eventually gave up and settled for the last one they sent me which still had light bleed and an I'll fitting shell. The charger packed up when it was a year and a week old so at least I know it won't bother me again.
Not sure what happened to Asus, their netbooks used to be really well built and last forever, I've got a six year old one that the other half uses every day. You would have thought that it would be cheaper for them to invest a bit in quality control than all this shipping of replacements and reconditioning all the faulty ones

I think you are right. If you think it's too dim in general, and not just because you put them side by side at lowest brightness, then that is not good. It's frustrating but if you are willing, keep trying. I think I finally found one that I can live with, after four tries!

[Discussion]Dead pixels, dust under screen..

where's the quality control, Asus? I picked mine up today... had a big old dead black pixel right in the middle of the screen... being as anal as I am about small things, I returned it.. got another... dust under the screen! I notice this one damn piece but I can't tell if it's dust or yet another bad dead pixel. kind of ridiculous but I'm not going to keep swapping these out. I'll live with it.. but still. whatever happened to quality control!? all new devices have such a higher rate of getting dead pixels or screen defects, it's ridiculous.

First one had a stuck green pixel that was immediately noticeable on the "Google" boot screen. The replacement has a thin line of light bleeding along the top. It's not totally awful, but I'm wondering if other units share it. I researched it a bit and the bleeding on mine isn't as bad as it could be.

Whining about 2 bad units. 10 of us got our tablets and perfect screen, 9 with 0 light bleeding. Mine has a small line on the left side which is barely noticeable.
If you get bad manufacturer units, use the warranty. Is there for a reason.

Hmm..for once I got a perfect device. I got used to backlight bleed. You should see my zenbook prime...that's a mess.
Sent from my Nexus 7 using Tapatalk 4 Beta

Had to exchange one at Best Buy today. (The floor manager walked back to the back where they were still in the process of emptying the truck to get me a new one!) There was a line about 50 pixels long about a half inch above the navigation bar that looked okay until i started swiping through the play store. The pixels seemed to be mirroring certain colors, it was strange. Anyways the exchange was effortless and my new unit is flawless!
TL;DR... Very glad I decided to go with Best Buy for my purchase.

I haven't noticed anything odd so far with mine. No pixel issues or backlight bleeding that I can tell. Only thing going on is the JSS15J update issue. Mine came from a Best Buy that seems to have had it in the stockroom for at least a day. The closest one was still unloading their truck and didn't know if/when they would be there.

I noticed three spots on my screen that looked like dust or deal pixels under the screen. Hard to tell which, because of you can notice the black spec then it's a lot more then a single pixel that's dead due to the high dpi. I exchanged mine and so far I haven't noticed it again

Mine is perfect

No issues with mine. I even did a pixel test. But yes; dead pixels and dust always suck. I've swapped a droid x, one Note 2, two HTC rezounds, a iPad 2 and 3 all for dead pixels or lint. Almost forgot about the Nook HD plus.
The take away is that no company is immune to this issue. The worst out of the bunch was the HTC rezound. The dead pixels would cluster in groups. Even the 3rd phone had a dead pixel but I lived with it because I got it at a good cost.

I didn't have any dead pixels, but I did have a lot of apparently random dead spots across the screen, so that I was unable to trace a solid line without it spacing out.
I would have icons I was dragging just drop, or random presses happen. For the first bit, as I was tinkering at work, I was unsure if it was overly responsive, but testing when î got home diagnosed it.
It's wiped and ready to exchange as soon as the Best Buy opens today, and them in get to go into work on the weekend so fingers crossed.

Rats. After I had to RMA my original N7 3 times due to screen lift and a broken backlight I thought I was lucky when I received my new N7 and didn't notice any imperfections. Then I saw some dust or dead pixels or something near the bottom http://i.imgur.com/gDJxmgz.jpg. Oh well, at least Amazon is sending me a new one and I have until the end of August to send back my current one for free.

My bezel had a ton if scratches on it out of the box. There is no quality control at Asus and Google needs to ditch them. It makes google look bad

Sent from my Nexus 7 using XDA Premium HD app

Is it just a sticker?
Also are they from different manufacturing months (on the box if you still have them)?

They are both 07 2013, both bought in north america, and it's printed, not a Sticker.
More precisely: both bought in the United states.
Sent from my Nexus 7 using XDA Premium HD app

mine says made in china 2013.7 on the box, but nothing on the unit itself.
edit: ok i looked again and it is on mine, had to use a light and get a look from an angle.
i also noticed that the box says "perchlorate material", which some u.s. states classify
as a hazardous waste. hence, i assume, the trash warning.

It's normal, never noticed it on mine until closer inspection plus the fact I put a case on pretty much straight away but it's there under the 'ASUS' branding only fainter than the one shown below.

Most of the images on Google of the Nexus 7 will be from specific site reviews, not many individual buyers will put up high res images of their unit.
Still you could be onto something but I thought electronic devices had to display that info anyway, the original Nexus 7 had it displayed as a sticker due to the soft touch material back.
Also I would thought it'd be the other way round having info for retail & not bothering for demo units etc.
Or maybe just they ran out of stamping ink or forgot with some units?

Both my Nexus 7 2013 and my Nexus 4 have that on the back. I wasn't aware any units were sold without it, thought it was a legal thing (the same info is normally under the back cover of phones, but neither of these devices have removable backs)

Strange how some have em and some dont
it could be to do with shipping aswell but strange
its from same place

AlderCass' picture shows exactly what i mean. The unit i am writing from now doea not have that. both were warehouse used - like new versions from amazon by the way.

Mine don't have them. Wonder if these correlate to touchscreen issues.

I would just sit back and wait for KitKat. Mine was perfect till it updated. I have since been able to fix it with sfhubs fix. There is nothing major to gain by updating

This might shed some like on the whole thing: http://en.wikipedia.org/wiki/CE_marking

Yea DON'T UPDATE it.
You could probably install a custom rom though to get newer versions that don't include the updated touchscreen.

as far as i can tell, both of my units have little to no touchscreen issues. little enough for me not do anything.
the version without the ce logo runs paranoid android rc 2.99
the version with the logo runs stock android 4.3 (ota update installed)
abut the ce marking thing: that means the one with ce marking could have been sold in europe to. Then I still wonder why they bother to make 2 different back cases.
