ok so I have returned 3 nook colors for the whole ghost touch/random selecting of things....Anyways I noticed on CM 7.0.2 currently the best ROM for the Nook Color out there that the lcd density is at 161 in the build.prop file I like things bigger so I set it at 230 or so and I have been messing with diffrent settings. It seems to me that at the LCD Density Setting of 161 or so that the stock CM 7.0.2 comes with does virtually no/minimal ghost/random touch compared to say a setting of 230 or so.I have tryed stock roms n all the rest and it seems they all have the same problems with this matter. I guess my real question is does CM 7.0.2 have a setting of 161 for a reason? And if it does is there a way to fix to this issue and get a better size say of 200+ on the lcd density settings?
I don't have the full story on why 161 but I know part of it is that alot of apps won't render properly with a setting of 160 so to answer the lesser question 161 is intentional.

Ya thats what I was just reading but Im curious about the fact it seems at least to me being though 3 nook colors that the problem is more software related somehow some way rather than hardware if anybody has any thing else that would be cool....thanks! And btw another forum I was reading earlier said something about the software how it members where you touch and if u exchange for a new nook color like I did of course it will be better at the start but eventually will be the same old issue
You may just need to re-calibrate your screen. I haven't had issues with ghost touches other then when trying to use it while connected to a charger.

Ya Im fairly use to the adb method of recalibrating the screen and also the app on the market that seems to help for a couple of mins. And so does flashing or restoring the rom and the usual screen off/on trick and the reboot I have been round the block with this thing once or twice

Not the same old? So you're using the NC while plugged in? Or a really dirty screen, or wet, or..?

What this man says! The nook color screen is very sensitive, your screen doesn't have to even be very dirty, it can register old fingerprints as touches, any time you get ghost touches, just turn your screen off and clean it...
I noticed there was a calibration APK in the stock 1.2 rom, however it won't install in CM7 and I couldn't find how to run it on the stock rom.

I have been using a density setting of 220 on the NC for weeks (and my DroidX for almost a year) without noticing any ghost touches. I recommend the same as above... if you get ghost touches, turn off the screen and clean any smudges.
most ghost touches i experience are due to thin layer of condensation on screen, usually first thing in morning when the screen is cold but my hands are warm
My original NC had the ghost touch issue, and it was driving me nuts, so I exchanged it for a new one last week. The new one works great. I haven't cleaned the screen at all since getting it a week ago, so it's pretty dirty now, and still no issue with ghost touches. My feeling is that there is a hardware issue with many NCs.

I dont think its a hardware issue at all, every time i've had the ghost touch issue, i was able to fix it by cleaning the screen. It doesn't matter that your screen is just dirty, what matters is what its dirty with, since the screen is capacitive, it would have to be dirty with something conductive...

Well my original one started acting funky after just a day or two, I kinda thought that it was software related because I was running CM7 nightlys at the time, but later realized that the issue persisted even with stock. I did find that I could reduce the issue by cleaning the screen, but it didn't help completely, and would only help for a very short time. Since exchanging for a new nookcolor, the difference is night day. I am completely convinced that it is in fact hardware related, based on my experience with two different units.

As explained by the man himself;
dalingrin said:
You can use 169. Despite what people think, 160 is the best value to use for the Nook. Anything other than 160 means extrapolation or interpolation must take place. This is why nearly every HDPI phone uses 240, not 231 or 248, despite their real world DPI.
However, there is a bug in the Android Market @ 160 on tablet size screens. For now I have it set to 161 to get around that bug. I don't use 169 because icons and such are more blurry due to the extra extrapolation needed.
Until Google fixes the market there isn't a good DPI for us to use. Each has its own problems, 161 has a line in the notification bar but sharp icons, 169 doesn't have a line in the notification bar but has blurry icons....etc

Regarding ghost touch issues, while there may be some units that have this problem due to hardware, IMHO most of them are due to the sensitive screen and dust/dirt/oil/condensation. Just the other day I was plagued with ghost touches because it was unusually humid in the room I was in. As has been posted by many, easily fixed with a simple good clean.
Had my nook for over a month now, and just noticed this problem this weekend. I had to clean the screen real well (didn't even look that dirty) and the problem went away. FWIW I have a screen protector on it (added it a couple weeks ago).
I have never seen any ghosting issues. Im running cm7 with a default density of 161 i got my nook at the beginning of the year. ive pretty much run every version of cm7 since it was released.
I had it a month or 2 before i got a screen protector. (official b&n, antiglare)
I did have to clean my screen really well prior to applying the protector. i dont think ive cleaned it since.

I have a Zagg InvisiShield, installed a few days after I got my Nook back in March, no ghost touch issues that I have noticed.
The ghost touches have 'nothing' to do with hardware, roms or applications used. Its entirely due to something on your screen such as grease, oil or something similar like the previous posters said. When or if it happens, turn off and clean your screen. That's it. All tablets can produce weird touching behaviour 'especially ' if you use something like a screen protector.

I beg to differ, ONE poster said something about it happening more when they have it plugged in.. I have playing a game that drains it pretty quickly, so if I can play on the charger I do.. but the problem is constant, even when my screen is PERFECTLY clean. The problem has all but went away entirely when I leave it unplugged, even with screen dirtyness. And came back within a few minutes of it being plugged in AND fully charged. I think it happened once WHILE it was charging, but THAT may have been because I let the screen be dirty while charging.
So yea, I have a feeling that there IS some hardware reason for this. Or even just as possible, something in the way the software reacts once it is fully charged. Either way, I have tested this for weeks and it has held absolutely true.
So thanks to the poster that mentioned it being plugged in, fixed my problem entirely

There is a hardware issue causing this but I think it is the cable/charger that is the problem. My Nook charger causes this issue but if I use a standard usb cable to charge I don't have touch screen problems. Some users have gotten replacement cables and no longer have the issue.
My Nook Color was all fine and I got a SD-boot of 2.3 CM7 working perfectly!
However, shortly afterwards, I noticed my touch screen kept 'touching' where my fingers weren't. The touchscreen appeared to have gone mad. I couldn't even use the device without having to power off/on the screen every minute or two. It makes the device basically unusable.
Anyway, is this a hardware issue - or is this a known issue with software somehow?! I did notice the issue somewhat in the original boot of the nook, but now it's seems WAY worse (not sure if it's because I'm using it more.)
I've had this exact problem a lot, and I've yet to actually find an answer or a solution on it. It's definitely hardware-caused, though, as I've had Honeycomb, CM7, and Phiremod on here and all of them have given me problems.
I've seen it go crazy when I plug in the charger. Some sort of electrical weirdness with the touchscreen.
Yes, usually when this comes up, the main response is that this is common when the nook is plugged in. Also, try cleaning the screen. I guess both can cause the phantom touches. I get the same thing every now and then. Turning the screen on and off, and cleaning it, seems to help.
First, clean the screen.
Then, turn the screen on and off.
Download Nook Screen Reclibrate and run the app.
Then buy a screen protector!!! Helps a ton! I use Zagg invisible sheild

That. Fixed it for me permanently
THAT's why I had a bunch of screen protectors in my Amazon cart! Lol, I couldn't remember!
Is there a certain brand you guys recommend? Every one I've used in the past has been junk, and it's hard to tell from some reviews if they were just not put on well. Do the matte/anti-glare/anti-fingerprint ones work well?

I must have gotten lucky I just bought a three pack on eBay for $3 of the crystal clear ones. As long as you get it on dust free its great. Make sure to buy more than one because one spec of dust will leave a bubble and ruin it.
Nook Crazy screen
After trying many things and reading many threads I eventually found that storing the nook on it's back as a norm is not a good idea. Dial indicator shows a screen bow inwards. Store you device in a face down position for a day or two and the screen will release unwanted touch commands. Hope this will help.:victory:
Hello,
I just rooted my NST successfully with Touchnooter. After I used it a few minutes (about 5 mins), I found a black spot in the middle of my screen which won't go away.
It's everytime there, no matter what I do, even if it's off I can see the spot.
Powering the nook off and on again doesn't help.
Since I imported it, I can't replace it. That's what makes me really, really sad. Is there any way to fix this stucked spot?
Send the picture. It may help understand what is happening.
I'll do a picture if I'm at home.
After I used ADW Launcher and opened the App Drawer (where I slided from left, to right, etc. to look for the app i was searching), I got a stuck pixel (the e ink display doesn't have pixels? that's why i called it ink spot or stuck spot).
It looks like a dead pixel which is black all the time, even if my nook is off.
There have been a few reports of dead pixels.
I heard that somebody got an exchange because of it.
I doubt that anything you did with rooting caused this.
There are multiple "pearls" or blobs per pixels. See this microphotograph:
http://www.flickr.com/photos/pamoroso/5407255967/in/photostream/lightbox/
I don't think that you are seeing a single pearl getting stuck.
It seems to me that the problem must be electrical.
If it were me, I might try just for the heck of it to see if it could get "unstuck".
I'd try some full-page black white transitions, but I wouldn't hope too much.
I'd go for the unrooting path. If it comes back to original state, re-root again and check if the problem shows up again.
Forcing a black screen and coming back should work (sort of a screen reset), maybe a screen check program would do the trick (look for it in the market).
I already did use my backup, but that didn't help, sadly. It seems to me, that this pixel is burned in the screen now.
I also used a whole dark screen because I also hoped to reset this pixel, this was also not working.
Aww, it's driving me nuts. Is there really an app in the market that could help me? Because dead pixel at an e ink device aren't that normal. Oh well, so sad. And I paid 200€ for it + 1 cover + 1 light because of the import, now that. T_T
Thanks for your replies, apeine.

Yow! They were selling refurbished ones on eBay for $65.
http://www.ebay.com/itm/Barnes-Noble-Nook-Simple-Touch-2GB-Wi-Fi-6in-Black-/300688948315?afsrc=1
Hmm, well they seem to be $79 now.
So, nobody knows a fix? T_T
like already said thi is a hardware issue..
it happens if you root or even if you root not..
its like you said a dead pixel.(on a TFT its not that bad because there are more pixel)
use the support(remove the root before)
thats the problem with a importet divice
its not cheap incase of an supportcase
As much as I like the Nook Simple Touch's general design, I have to say gross light diffuse!!! One day of use, extremely extremely extremely extremely extremely extremely extremely extremely careful on the screen. Now I have a white spot (when Glowlight is on) and black spot (noticeable on white background). Come on B&N! I really liked Nook (still do), but going with new Nook Glowlight (2013) is not an option for me at all. Up to now, no eReader can come close to the lovely Kindle Keyboard. It's like Windows XP of Microsoft products! :laugh:
P.S. I guess the black spot occurred because of rooting, if not just because of bad design of NSTwG.
The black spot was definitely unrelated to rooting. The fragility of the light diffuser film is a very well known issue since day one. When the glowlight first came out bloggers posted pictures of their damaged bright spots. Though of course B&N never admits anyvsuch thing on their web site, so people just keep unwittingly damaging them. Get a replacement and use a case that protects the screen at least when not reading. I use a Speck case that has a formed shell that snaps onto the back and a hard book cover front. The whole thing is covered in fake leather. The inside of the screen cover is velvet-ish. I damaged mine too when I first got it. I was extremely careful too. Since then I use the case religiously and I know not to let anything touch that screen at all not even casually. Just my fingers. Since then no problems. I agree it is a bad design to be so delicate and bad policy and bad customer treatment not to warn you about it.

Thanks! yes I was aware of these issues right off the bat, but bought one as my 2nd eReader. Believe it or not, after this happening, I'm just more in love of my K3. It's just such a sturdy beast! Best of all readers, for me it even defeats Paperwhite or what not. It gets beaten around in my backbag etc. and I've had it for several years now. No wear. Handsome as first day.
My plan was to make this my main eReader, but now I can't fully trust it, so it'd still be my night time reader. Now my plan: get a case, be even more careful... and cherish K3.
Edit: Well, I have to say that the black spot is extremely small, like 1 pixel. You have to really look close to notice it. The white spot is even smaller and just noticeable in Glowlight and from one direction! From 3 other directions, it's not noticeable at all. With this, I realized: 1. The device had been like this since I got it in mail. 2. Rooting has nothing to do with these issues.
I still love my NSTwG though.
So my Nook Color's been having some issues. Basically the 'phantom touch' bug and sometimes the screen isn't responsive when I turn it on. Both issues go away if I just turn the screen off and on or turn it off and rub it down with a cloth with a bit of rubbing alcohol on it. The 1 year warranty runs out this August and I was wondering if I'd notice a difference if I sent it into B&N to get a 'certified pre owned' Nook. Is the quality any much better or worse? Also will there be a chance the issue will be fixed in a model B&N's deemed to be certified or is a problem across every NC?
No, it's *not* a "standard" problem.
My Nook was bought new, but I have since bought two more refurbs (for wife and daughter-in-law); both were perfect.
I don't know about the wake issue as I've never experienced it, but the phantom touch I've had a ton and always resolved it by cleaning the screen. The Nook Color is known for phantom touches on a dirty screen. Getting a new one won't really help (unless you can confirm its a hardware issue). I'd say almost every touch bug I've seen has been resolved with a good clean. Its the reason I keep a small cleaning cloth under the Nook itself in its case.

The B&N refurbs are usually in good shape. I wouldn't hesitate to take one in exchange if there's an actual hardware problem. Is your unit rooted? You could try running Nook Screen Recalibrate (from the Play Store) if so. If cleaning the screen helps, you might try using a stylus. A microfiber cloth really helps with cleaning.
Just like in topic. Does your NSTR make a sound while refreshing screen? Its very quite (you have to move nook next to your ear ). Im using ereader for about a month but ive noticed this today. Is it normal or maybe I should be afraid?

ur nook body do sound.... or u do root nook and use usb host mode for run sound on ur nook?
Body of Nook... Screen/electronics makes a very quite (but noticable) sound (like a buzzz) while refreshing screen.
It sounds like millions of tiny little balls playing "Red Rover" in a viscous liquid.
Which is what is actually happening.
(Red Rover = children's game where you say "Red rover, red rover, send ... right over".)
Ufff... So it's normal... What a relief!
