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 left mine unused for a month.
Now, there is a ghost image permanently imprinted on a quarter of the screen (a partial image no matter what page I am on, blocking the readibility).
I understand this is what they have screen savers for, to prevent burn in images from permenantly forming. I think it is a malfunction of the screen saver, so it was held at a single image, which burned in permanently.
I will try to return it for a replacement, though BN is acting is if it's my fault, asking me over and over again if i dropped it. The person I spoke to had no idea what a burned in image is!!! As well they are very disorganized regarding how to make arrangements for a return, had to spend 3 hours yesterday to do this! Unacceptable.
I think their tech suppert is substandard, and this is a key issue for the future of the Nook, or any BN product.
Since I am stuck with the Nook (assuming they will give me a new one), I would like to know if there is a way to prevent the screen saver failure, or if the ghosting is due to some other problem. Perhaps if I root the machine I can use my own screen savers, or even choose to blank the screen out. If there is no image when it is "sleeping" there would be not ghost!
Would rooting it help me prevent this from re-occuring?
Thanks
I'll be uploading an image of the burn in later today, if I am able to.
Root?
Is it rooted?
You need to return it to the Store! DON'T call tech support. When you are in store you are actualy talking to a human, not some rep crampted in a qubicle in India.

I returned my ghosting nook via mail, as reported above they refused to allow me to switch it to the store.
My main question remains unanswered: how to prevent ghosting in the future. Any other thoughts on how to prevent this? It is currently unrooted, but will root it if it will help me prevent it from getting another burn in image
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?

Seems that this is a kinda major problem. Iv got same issues

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.
Hello!
I recently purchased a broken S4 with a 'flickering screen' issue. Normally, people are told to return the phone for a replacement, but I can't do that.
In more detail, the problem begins after using the phone continuously for several minutes. The phone works flawlessly regardless of the broken glass screen, but after a while, begins to flicker. Only slightly at first, but then more and more severely until the screen shuts off. Turn the screen on and off again, and it's back to normal. (you normally need to leave the phone for a while before turning it back on, or it'll quickly just flicker itself off again). This to me suggests an over-heating problem, but I can't be sure.
I've wired the phone up the the TV using cheap cable, and the flicker doesn't show on the TV. That is, the phone starts going mental, doing its flicker thing, but the image on the screen remains constantly smooth when swiping - no flicker.
So... is this an image with the digitizer or the cable attaching the digitizer to the motherboard? If the screen doesn't flicker on the TV, that means we can rule out a motherboard issue, correct?
I just want to know what part of the phone to replace really. I don't want to buy a £80 digitizer only to have the same problems once it's been replaced.
Any suggestions welcome, cheers!
Based on your testing, it's very likely that you can rule out the motherboard. Unfortunately, that leaves the screen. You'll have to replace it, and you can reuse the existing midframe, but save as much of the adhesive as you can after peeling the old screen off, as the new screen doesn't come with adhesive to mount to the midframe.
Unless of course, the place you buy the screen from includes a small roll of the stuff.
Hello,
As @Strephon Alkhalikoi said it may depend on the motherboard.
Sometimes the kernel may be the cause too, I suggest to try first to reflash stock ROM. Here you can find how-to
With due respect to Antaresone I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
