Hello.
I could not use the device for some time. It lay on the shelf for a month. The device was switched off. When I got it, I saw the horizontal bands on the screen.
If you turn the nook, the bands disappear. But traces of them can then be seen on different pictures. If you read about 100 pages, the bands disappear finally. If you turn off the device at a time, such a day, the band appear again.
Obviously, this is due to the power supply to the screen.
But, it is a defect or a feature of his screen work?
Hayz, this is an uncommon behavior of the screen. Any sort of ghost like this should disappear after a few page turns, and shouldn't come up during sleep.
I'd go for defect.
I also have to put my vote in for some sort of defect, if your device is rooted I'd unroot it and see if it persists. If it does at this point I'd go to your local B&N or call B&N and get it replaced.
ghosts in the nook
started new thread is the nature of the artifact was different, actually a "burn in image"
Use NookRestore.img on your NST if it is rooted and then go to your local B&N and they should replace it for you as long as you don't mention the root.
Hello all,
I've recently purchased my first android device and wow is it cool. I've installed several different ROM's on it (CM7 253, Cm7.1, CM9, Cm7.2). What I've noticed is that the bottom has some issues that may hardware issues.
When I'm in a draw program I cannot draw fluidly near the bottom near the N button. Also when I use the pointer control utility in settings (forgot the name) it is nice an fluid for all of the screen EXCEPT on the side where the N button is. It will seems to get sporadic and will make contact, and not and I'll get dots and dashes instead of a nice fluid line. The soft buttons work fine but require more of a firm push when position in portrait mode.
I'm thinking hardware? This is on a refurbished nook BTW.
I can't get to the device as it's under the tree (for my wife).
Can someone test this and tell me if yours can create a fluid line drawing near the edge where the N button is?
Thanks,
Zack
I bought 9 NCs as christmas presents this year, I had to return 3 of the due to hardware problems (Thankfully I tested all of them the day I got them).
One of the ones I returned had poor touch sensitivity on the bottom of the screen which got progressively worse over a few minutes of use. I had to retype several letters when I was putting in the wifi password then it went into standby and I couldn't unlock the lock screen because it wasn't detecting my swipe. It would just jiggle a little. By the time I took it to B&N it wouldn't even jiggle. You'll have to send it back to a place in Reno but going into B&N will save you some time on the phone.
The other 2 had busted wifi (no signal even in B&N) and a sticky power button (every couple of times you tapped it it would stick and turn the device off). There's also a few with blue tinted screens but I didn't want to return those and play refurb roulette again.
Oh, and I just did some drawing in canvas (the notion ink app) and other than having difficulty drawing a straight line my nook works just fine along all the edges.
Wife got the tablet today and loves it. I was just mucking around with it and found the nook screen recalibrator and that seemed to completely solve my problem! Whatever isin that magic potion is great.
yeah, there can sometimes me issues with the digitizer that are almost universally fixed by screen recalibration.
I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

I agree it sounds like software since the reboot fixes it but your issue doesn't seem that common. I've seen a couple now that are somewhat similar but not like the pervasive left screen glitch. I would try an exchange personally.

Well sorry to burst the bubble but doing a reboot to resolve the problem doesn't really rule out a hardware issue. A hardware issue can be intermittent, there's nothing that states that it must be permanent. Furthermore it might not be the rebooting that resolves it but the time that passes. In other words, the problem might occur only at 6:45PM and last for 30 seconds, if you reboot it you might not experience it again. You have no time machine so there's no way for you to really figure out when it will occur and for how long to find out what's causing it.
It's all tricky. Some errors can occur both due to software and hardware so it's hard to determine which is actually causing it for a specific issue.
But a few things lead me to believe it's hardware.
1. Why aren't more people experiencing it? A software issue results in far greater people experiencing it, especially for a group as homogenous as TF300T owners who all own the same device. The conditions are already ripe and unless a third party app is causing it, everyone is running the same code and therefore more likely to experience the problem. A hardware fault would have to be deeply ingrained into the construction, the likelihood they had let it progress that far is unlikely. Instead, it seems like a QC issue which only affects a few individuals like you.
2. Touch screen issues have been noticed in not just this device but others. It can take on the habit of registering ghost input, no input, etcetera. Happens on the Nook Color too. Happens when the device is unplugged but mostly when it is plugged in to a power source especially the wall mains. If you're not getting it from your wall mains, it's probably the device. If it is your wall mains there's nothing you can do about it.
3. There's nothing random about handling touch screen events so I find it hard to believe this is caused by software. It's more likely it's a bad touch screen feeding false events to good touch event code. The likelihood code is doing this and doing this where only you experience it and not many others (actually I've seen no other people complain about this for the TF300T and two other people complain about it for the TF101) is really low.
IMO: Just exchange it. If you make the mistake of never exchanging it you'll be stuck on that boat forever. It's probably poor QC. If the second one has the issue, that bumps up the likelihood it's a software issue as these issues in hardware are very rare and I don't think two possible units experiencing it is very common unless it was a far more common software issue. If it occurred again I would either exchange it again or get a refund.
So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.
Check the running apps it's most likely mem related
Hi,
I've had two of these for about a week now, one for my self, and one for my 10 year old. I had to go into settings and shut off all kinds of stuff that was attempting to auto updated right off the bat. These don't come with a ton of memory right out of the box.
If you press on the bottom left corner of your screen the two little squares, it will show you what is loaded in memory. Every thing that comes up on that list on the left hand side is a opened application that is actively eating up your memory.
The only way to clear these apps once opened is to power the unit off, and then back on.
On both mine and my sons, I shut off all the auto updates, there are a bunch of different settings, you really need to go through them and look too many to list but a bunch should be turned off.
I don't have any issues at this point, neither does my 10 year old, he's always playing games like Fruit Ninja and normally has three or 4 youtube windows in the back going with in 5 minutes of turning the thing on and no issues.
Mine I use more for business related stuff, and also no issues. However right out of the box the first day it was a bit flaky. They both run smooth now.
I'm just waiting on some one to give me a root app for .26 since the second I turned these both on they updated the OTA firmware which took them off .17
Anyway I hope this helps.
Good luck.

Sorry didn't see the post about issues with where you pressed the screen. That one sounds like you may need to take it back in to have serviced. I tried what you said with squeezing the screen, and pressing the back in different spots. Nope, no issues like that. I would say it requires service.

The button you refer to in the bottom left is the multi-tasking button. If you press it and swipe an app, it will be removed from that list. Android usually runs fine with lots of apps sitting in ram. The only real exception to this is apps that are poorly coded and will try to run in the background all the time.
If you want root look in the development section, there is a simple utility to let you downgrade to .17, root, voodoo backup, update, and restore.
I have same/similar problem see other thread

See here for my symptoms.
So, last night I took the tablet back to Best Buy and exchanged it (actually, had to drive to a second Best Buy because the one where I bought mine was sold out!). So far so good. Though I've only had the replacement a short time, I'm feeling good about this one. No hiccups so far. And upon running the initial setup I remembered that even during the initial setup of my first one, the screen had become unresponsive once. All in all I've got a good feeling about this one. And I do desperately want it to work because, man, I love the concept and execution of this thing.
Have you tried the creaky test with the new one to see if it's a manufacturing issue indicative of all TF300T's or whether it was just an isolated QC incident?

Had the same problem from yesterday, I bought it from Amazon U.S and now i am in China which makes me hard to exchange it.
http://forum.xda-developers.com/showthread.php?t=1764971
Seems that this is a kinda major problem. Iv got same issues
Sent from my ASUS Transformer Pad TF300T using xda app-developers app
I bought this thing first off of Amazon, and it was backordered... So I canceled and ordered from Newegg. Fine, i have to pay for shipping, and wait longer, but whatever.
I get the tablet, so excited, and i notice first that the screen would switch orientation when it shouldn't have. Like if i have it in landscape, then lay it flat on it's back, it would go into portrait. This could be recreated every time, so it wasn't just a fluke. I installed Asphalt 8 Airbourn and tried to play. I held the tablet flat, then all of a sudden when the car took off, it took a sharp right and ran straight into a wall.
Great... the accelerometer is broke. Also i can see the backlight flickering a little bit.
I request an RMA from Newegg and they said it'd take probably about a week to get it back. Get it processed, about to go take it back and check their site to see if it's in stock still and it's sold out. I get on their chat to make sure and they said it's backordered, so i'd have to wait for it to come in or switch it to a refund. So i switched it to a refund and by that time, Microcenter in my area had them in stock so i dropped by and picked one up.
Go it home and it was acting fine, until i installed Asphalt again and then it ran the car into the wall again... Also, again, i can see the backlight flickering. Starting to get depressed, i contact Nvidia asking if this is a common problem and then they said it was the first they'd heard of it. They tried Riptide GP2 and said it worked fine on their test tablet. So i bought Riptide GP2 with my Google Opinion Rewards and tried it, the little water craft ran straight into the wall, just like the first tablet. They told me to try exchanging it again, and that they were sorry that i was having trouble.
I go back to microcenter, demonstrate what is happening, they give me a new tablet and tell me to install the game and test to see if this one does it before i leave with it. Their wifi was being crappy, so they gave me a USB Ethernet adapter and an OTG cable to connect to their Internet (it worked instantly, freaking awesome.)
Install updates, install app updates, install the game, it works... Finally have one that the Accelerometer works... I leave and go home, and the screen still flickers on this one too.... So thats the question part of this post, does anyone else have this tablet and notice the backlight flickering? It happens more often on darker brightness settings.
Other than the problems trying to get a working tablet, and the screen flickering, i love this tablet. The screen is really sensitive though, so when you're holding it and trying to hit edge of the screen, and you're barely touching somewhere else, it'll usually give you a hard time. The stylus is awesome, the screen can be very bright and easy to see out in the sun. The 1080p is a noticeable different over my 2013 N7 ( i can see the pixels in this tablet, i have very sensitive eyes and the ability to see very fine details) but it's still a great screen. the battery life at least for me is not as good as the 2013 N7, however it does make it through the day.
anyways... TL;DR: Love this tablet, had a pain in the ass of a time getting one that worked though. Also, does anyone notice the screen's backlight flickering like i do?
is it a continuous flicker or is it just slight changes in brightness when the screen content changes? there is a known "feature" called prism that does some kind of auto/dynamic brightness/contrast adjustment depending on whats showing on screen. there's a thread over at geforce.com about it. apparently it was introduced in a prior update on the other shield devices too so im hopeful its fixed. if its a true flicker and not just brightness changes, then its either defective or the backlight is pwm and you can see it. some people are sensitive to pwn backlights on regular computer monitors and can see the flicker. google pwm backlight if you're unfamiliar with the phenomenon.
It happens when the screen content changes, and i figured it'd be some kind of dynamic change.
it also happens when the screen has the content on screen constant. It's sort of like a pulse, sometimes it also gets bad for a split second. I don't really know how to explain it. it will be pulsing, then it will have a bad flicker then go back to pulsing. It gets worse the darker you make the brightness, and also when you turn on autobrightness (although im sure this makes it worse because it's trying to adjust the brightness in dark light).
I looked up the pwm backlight and it looks like it's mostly with LED backlights. Thats my guess of the backlight on this tablet. That makes sense though, because i can see a VERY VERY slight pluse on my work's Macbook Pro, and a slight pluse on my Nexus 5 too. I suppose that this might be the case.
I just don't see it being a defect because i've had three of them, from two different vendors and they've all done the exact same thing with the backlight.
I haven't noticed any screen flicker.
I am also comparing this forum with the N7 (2013) forum when it first came out.
Lots of people there seemed to have troubles getting a good one -- light leaks, touch screen issues (there were several firmware updates for this), dead pixels, etc.
At least so far, there seems to be fewer people (per captia) complaining here.
Speaking of touchscreen issues, I did notice something about my Shield Tablet...
I was using it in the evening, while connected to a charger. I suddenly had a terrible time typing. I had just installed Thumb Keyboard, so I thought that was the problem. Went back to the Google Keyboard. Still had trouble. Scrolling web pages was also slow/erratic. Reboot -- same thing.
The next day I took it to work -- lots of email, including lots of typing.. general usage, etc. --- all with no problem. Back at home in the evening, some games, Google+ (typing) -- no problem.
Later on I was surfing eBay, and again I could not type or scroll without a lot of problems.
I turned on Settings --> Developer options --> Show touches and --> Pointer location.
With my finger steady on the screen, it was showing lots of erratic movement, particularly in the vertical axis. Several mm of vertical error, and about 1mm horizontal. Sometimes clearly below the entire area my finger covered.
Then I realized that both times it happened I was connected to the charger (Travel Surge protector with 2 -- 2.1A(shared) USB outlets).
I disconnected the charger, and the problem went away.
Connected the charger, and after a few seconds, the problem returned.
I was using the included cable, and another 2.1A rated charger.
I changed to a different 2.1A rated charger, and did not have the problem.
Different cable, 1st charger -- No problem.
The problem is reproducible (although not always) only with the 2.1A travel surge protector, and the included NVidia cable.
I noticed that this thing will charge at nearly 2A. The included cable is quite long (as compared to the other cables I have laying around), but is not thinker. In fact it is thinner than other USB cables.
It's really too small a wire guage to run almost 2A for that length.
It is marked with the Shield symbol (Like the controller or the Shield Portable), and came wrapped in a thing that said "Use with", and the Shield controller symbol.
Was the wrong cable in my box?
How are other peoples cables marked?
Has anyone else noticed an erratic touch screen if you use it while charging?
Mine is marked the same as yours. I just notice the screen keeps poping on while it is charging for no reason.

Yeah, there are a lot of devices that will freak out when you're using different chargers. I was going to tell you to go back to the Nvidia cable and charger that were included with the device to see if that fixes it, but it looks like you've found out that the charger was the issue.
I'm still unable to tell if it's the PWM Backlighting method that was brought up earlier or not. I can't get anyone else to see it though, and after three devices, i'm starting to feel like it's something that is normal.

Same thing happens with mine. While charging the screen will frequently come back on and then go off again in a few seconds. I haven't noticed the behavior when it's not charging. It's almost like something is running in the background causing it to wake up when charging.

I've noticed it slightly in low brightness but not as bad as the Tegra3 based N7 and TF700t. I'm guessing it has to do with prism if that's the case.

Screen "Flicker" is the auto brightness, try changing to a manual brightness. I have noticed the orientation is very sensitive, sometimes when sitting down or moving a bit it will flip orientation on me, seems overly sensitive, whereas ive used other tablets that were not sensitive enough. Sounds like you may have had a few bad ones but the screen "issue" seems to be common, the light sensor seems to be overly sensitive (assuming changing to manual brightness resolves your case).

I haven't noticed any type of flickering on my TN7 or my new shield tablet. This could partially be because most of the time i have the brightness setting to manual. Its seems as when i have it on auto the screen is just a little too dim for me. Although, when using the tablet outside i usually have it on auto and the screen chooses the correct brightness so it can be best viewed.
As I mentioned, I haven't seen anything I would call a "flicker", but I am glad someone mentioned the auto brightness.
To me, the auto brightness seems a bit "hyper" -- too much gain.
A slight change in orientation to or away from room lighting causes a drastic change in screen brightness.
The same for a shadow from my thumb if I hold the tablet in landscape.
I guess it could cause a flicker, but it depends on the context of timing --- Kinda like "the dinosaurs died out quickly", vs. "the quark decayed quickly".
Also I want it to be clear that I am not complaining about my Shield Tablet. It's just that xda-forums are a place where things are discussed in minute detail. It is not a problem, issue or complaint.
I have no interest at all in using my Nexus 7 (2013) (or any other Tablet) since I got my Shield Tablet.
The weak wifi appears to be the priority focus Nvidia is now giving the tablet. Question is will they go into denial mode like Asus did with the T700, or address early and revise the design IF needed. Sales were badly impacted for the T700 and a high return rate, per Best Buy.
Hopefully a simple firmware fix, but weak wifi is almost always antenna related for devices like this.

Tell me about it. Its been like that since I first turned the tab on 3 days ago. Nvidia refuses to acknowledge my issue and insists I pay return shipping and a restocking fee. I don't understand why I should pay more than every other customer just to get a properly working device. Nvidia has pushed me away from sticking with this tablet.
The flickering when the content changes is probably Nvidia's PRISM at work. Basically, it tries to optimize brightness and colour so that power usage is reduced.
Instead of maxing the backlight and telling the pixels to display dark grey, it dims the backlight and tells the pixels to display light grey, saving power.
It is an advanced form of autobrightness, and I think it can be disabled. But a continuous flickering should not be caused by this. This should happen only when the screen is refreshed.. like new page or picture
