Started having this issue on my phone 48hrs ago after it being left on the shelf charging from 5% battery overnight. So I'm using a 3rd party app to simulate the buttons for time being as a workaround (there's loads of variants on the Play Store that don't require root) until I fix it.
I had to replace a cracked screen on it a few months back (which was easier to do then I thought thanks to the iFixIt teardown. All has seemed well apart from some light blooms on the screen that I've lived with and now the buttons failing, and the part I ordered didn't come with the adhesive to reattach the back.
So I've now bought another screen\digitizer from amazon in the hope it'll resolve the issue and should be delivered within the week.
I've seen a lot of forums around the web for people with similar issues.
Tests tend to involve variations of safemode or factory resetting without restoring original. But this doesn't resolve the majority of cases, except the occasional temporary fix.
Solutions include; factory resets, flashing different ROMs, dropping at a 20degree angle, persistently hitting the buttons and re-seating a ribbon cable.
My thoughts:
It seems to me that maybe the Soft Keys area uses resistive touch section rather than capacitive touch, which would explain why the soft key touch area works in some instances but not others. It would also through weight behind it being a hardware issue. The capacitive multi-touch screen works fine, but the resistive section for the soft keys doesn't. Anyone have further thoughts on this?
Same without me
Easy test
Rotate your phone into secondary landscape mode. This will place the navigation buttons on the other end of the screen. From here, you will be able to perform the necessary tests to determine the validity of your theory.

Lol this doesn't make any sense, if it was a true you would be able to press soft keys with a pen or old stylus - this is how resistive screen works.
No part of this phone's screen is resistive. Sigh people that don't understand the basics of capacitive touch screens.
Thanks for the responses.
Yeah, resistive was a pretty far stretch of imagination, but I couldn't think what else it might be at the time.
Anyway. Replacement screen fitted and soft keys working again.:victory:
I can put off looking for a replacement phone for a little longer.

hi, i'm a new owner and there are a few things that are bugging me and i'm not sure if it's normal or if it's problematic.
-the start menu pops up sometimes when i slide out the keyboard. is this normal?
-the device can only be charged when the usb is connected to my computer, but not when the usb is connected to an ac adapter.
-keys are mixed up (i supposed because of the Japanese keyboard layout, and i think i saw a fix for this)
when sliding out the keyboard, it takes about 6-8 seconds to adjust from portrait to landscape(with the start menu popping up when going to landscape).
-is it normal for the touchscreen to be completely unresponsive when the keyboard is slid out?
-the touchscreen is completely unresponsive sometimes while the keyboard is hidden and i have to either press random buttons or slide the keyboard in and out to get response back.
sorry for my noobishness and thanks in advance.
ok i've managed to solve the keyboard layout problem and i guess the delay is typical,. but the following problems/issues still exist:
-the start menu pops up sometimes when i slide out the keyboard. is this normal?
-the device can only be charged when the usb is connected to my computer, but not when the usb is connected to an ac adapter.
-is it normal for the touchscreen to be completely unresponsive when the keyboard is slid out?

Hi ji1386
I'm afraid that does not sound good. I have seen at least two other cases where the keyboard being slid out causes the start menu to pop up. It was concluded that pressure is being put on the touch sensitive screen by the mechanism. This is a hardware issue and can also show as programmes suddenly closing for no ovvious reason and I think this may also be responsible for the touch screen not responding when keyboard open. In summary pressure on the touch sensitive screen somewhere when there should not be.
If the device is under warranty I'd go for an immediate replacement. Perhaps just before doing so I would try a HARD reset just to be sure.

No it's not normal. The screen should respond as normal. For example when using word, even with the keyboard ou you should still be able to tap for the soft keyboard, tap on bold, centre, tap in text to inser a word etc etc.
If you can't I think it's because the keyboard mechanism is somehow putting pressure at some point on the screen i.e the same issue as the start menu popping up. If a hard reset does not cure this then it's a repair job or replacement under warranty I'd say.

More bad news...since yesterday, the touch-screen no longer responds at all...completely unresponsive to tap or touch. I've tried hard/soft reseting and still got nothing...
I have however managed to get it to charge through a wall outlet. but it's a bit buggy...
Unfortunately, I bought this phone used locally and the guy isn't responding to any of my phone calls/emails, but whatever karma will come back to haunt him...I was thinking about taking this to a small claims court, but i dunno how to go about doing so and if my case will hold up...
anyway, I've had to take it to a repair shop. They said they'd order in a screen and replace it for $150 cad and it should fix it, if not a diagnosis charge of 20 bucks...
this should bring the total cost of this phone to $725cad...great...
Hopefully it solves all my problems. I'm guessing the start menu problem and the touch responsiveness problems get solved after this.

I certainly hope it works out ok. Changing the screen assumes (possibly correctly) that the screen is at fault. If the screen is fine just getting pressure put on it somewhere then it will be a bit of luck whether it solves problem or not. A key problem here is that the screen is sensitive to touch, even on the area under the bezel - which of course is absolutely daft. Combine this with the fact that there is not a lot of room for heat expansion and the slide out keyboard can cause minor distortions in the casing and you have potential for a certain percentage of devices to have problems. Thankfully now far less than early models but still being reported.
Good Luck
Mike
Took it to a repair shop this week. Opened it up and looks like a damaged flex ribbon cable (possibly from sliding out the keyboard or just a faulty cable) is the culprit behind the unresponsive touchscreen.
Apparently those are impossible to find (if not very hard). i live in Canada where parts for these phones are quite scarce, so I'm not too sure what i should do. The guy said he could try to find a replacement part, but it'd take almost a month.
Anyway, just thought I'd mention it to let anyone with unresponsive touch screens know. I guess just add this to the list of possible causes.
how did you fix keyboard layout problem
Ji1836,
Can you please let me know how you solved the keyboard layout problem.
I also have a softbank X01HT with a japanese keyboard layout. I have upgraded to WM6 BLACK 2.5. But some keys are mixed up like the dot and comma and others as well. I tried the fixes in the wiki but nothing worked.
Aprreciate your help.
When I slide out my wizard's keyboard, the touch screen doesn't react to any touching any longer.
Anyone know how this can be fixed? If I re-close the wizard, the screen is fine again.
Very strange!
Yes xtrange!?
Its soo xtrange
does you upgrade your wizard... or got this issue since you own the device?
maybe a drop!!!!
We need every info you have done since it works to the stops time.
Well, there's one of two explanations that seem most likely to me:
1) Your device, due to some software malfunction, no longer responds correctly to touch input while in landscape mode. To test this, with the wizard keyboard still away in the locked position, open the screen settings, located in the 'System' tab of the control panel. Select an orientation of 'Landscape (Left-Handed)'. Does the device interpret touches properly now? If not, we've found your problem. You can return to portrait (normal mode) by sliding the keyboard all the way out and then returning it to the locked position.
2) One of the ribbon cables, due to age, damage, shoddy manufacturing, etc., has become loose. This means that the force of your keyboard sliding out may push a few of the internal contacts into a position where they no longer make a good connection. If this is the case, your problem most likely can be resolved by opening the device and securing the touchscreen ribbon cable. There's a service manual floating around that can help you with this, if you're brave enough, but I don't suggest you try it until you've evaluated the possibility of a software problem.
Haha nice. I never paid attention to notice that display screen. You were totally right. Swapping it to landscape via software, it is still working so it must be an internal cable.
Do you know if the same cable operates the 4 way arrow keys on the front face of the device? up/down works, but left/right does not, but this is all the time not just in landscape.

Chances are the flex cable between the mainboard & the screen sub-assembly is faulty & needs to be replaced.
You can find them on eBay or buy a faulty unit off eBay & re-use the flex cable to fix your unit.

Anyone else notice that the edges of the screen on the cmda diamond, cdma pro, and the HD seem to be MUCH less responsive than the screens of previous devices?
I "miss" the exit and start menu buttons pretty often and its pretty annoying lol.
Also the notification/title bar area plus other buttons along the bottom and side.
The rest of the screen is more responsive certainly than say the vogue, mogul, diamond or tp. But its the edges of this and the last 2 mentioned devices that get me..
Well I also feel it's less responsive, but not so much actually. Besides this is caused by the technology of the touch screen.

You mean the edges or the whole thing? The main part I feel is more responsive...
Edge responisiveness depends highly on screen calibration. Try to recalibrate screen more precisely, I think situation should improve ...

Hey thanks a lot. Thought the same thing myself.
Re-calibrated as accurately as I possibly could.
Still no go. I would really like someone else to try this. Take out your stylus even and press in the very corner of the X-button...you get nothing.
Sort of fix: I found that if you hold your press just a little longer it registers (much better) though I'm not quite convinced that it's still normal nor complete.

Hmm...I wonder if I should try to get it replaced under warranty.
I would want to, but I have noticed the same problem in a sprint diamond in the store, a sprint touch pro in a store, and a friends sprint touch pro.
What do you (guys) think? Replacement? It could get really annoying...not being able to close out of things. Right now since its new and awesome and stuff I'm kind of trying to ignore it or whatever but...hmm idk.
The fact that the screen is less responsive near the edges is caused by an inherent technical limitation of resistive screens. The screen has no real bezel, and thus, the screen is attached to the body frame right where it ends: at the absolute edges of the screen Where it is attached, it cannot move. A little further away from the edge it can move (eg be pressed down) but this requires more force since you need to bend the screen much closer to the fixed edges than when you would press the center of the screen, which bends the easiest.
Don't know if this makes sense, but it's like a window... Hitting it in the centre will break it much easier than when hitting it close to the edges, since the glass bends much further/easier at the center, so the same force will have more effect.
Anyway, resistive screens have this problems, capacitive screens do not, obviously, since they do not rely on pressure.
If hitting the OK/Close button is a problem for you, just use the hardware button below the screen, the one with the arrow on it. It does exactly the same thing I believe. With 'I believe' I mean I assigned OK/close to that button using AEButtonPlus, which should be the default behavior for pressing it once. I find this to be much more convenient than trying to hit that tiny X/OK button.

Hey thanks for your informative opinion.
This theory seems to fit, except it doesn't quite explain nor fit with these 2 things:
1. I can apply a pretty decent amount of pressure in the corner with no results whatsoever. But I can get full results if I apply less pressure for about .5-1 second rather than just tapping.
2. I have never seen any evidence of this on any other resistive touch devices (vogue, titan).
Why in the world do these resistive touch screens have to suck so bad anyway? The HD is the best I've seen lately, but does HTC just suck at it, or is it everyone (haven't owned a non-htc ts device for a yr or so, and that was a treo where I didn't really notice sensitivity).
My dad has a 3+ yr old Dell Axim X5 and that screen is AMAZINGLY sensitive. Responds to stylus and is too old to be capacitive. But it is literally 100% as responsive / sensitive as the screen of the iPhone. When I used it I couldn't believe it. You had to be VERY delicate and careful and trying hard to touch that screen and not have it know.
Hi,
I think I may have made a mistake, but was wondering if anyone else has / has not had a similar experience.
I got my Touch HD a couple of weeks ago, and although I was completely knocked out with its amazingness ( new word, patented by me! ), something bothered me about the amount of pressure I was having to use, particularly in the centre of the screen when touching.
I know there have been tweaks and hacks posted and the pressure required on the touchscreen is variable, so I fiddled and tweaked and carried on. It was only after I started using FingerKeyboard2 (which also warrants "amazingness" status.) that I noticed that when holding keys down and releasing for special characters and numbers, my HD was registering a second press upon release. So when holding for number "5" I got a letter "t" too when I released. This really annoyed me.
I've had a look from a varry shallow angle at the screen, with the device turned off and pressed in the middle and compared to the edges, and it seems as though the digitizer "domes" over the screen. There's a large void in the middle that's not present at the edges, which means that to register touches in the middle, I have to press the digitizer against the screen. I think this is causing the double presses, and having to apply extra pressure in the middle.
Anyway, to cut a long story short, I've taken it to CPW today and they've sent off for a replacement, which will arrive on Monday
Has anyone else noticed this, is it normal and I've sent a perfectly good Touch HD away? Have a look for me please, and spare an old(ish) man his sanity!
I can only speak for myself but, specially after tweaking, the hd screen is VERY sensible to touch, no need for hard presses at all. I think you actually had a faulty machine...
My touch screen is very good, shame the wifi has died on it and it's doing strange things. Mine will be back to CPW as well
My touchscreen works very well, without tweaking I think it does the job and recognizes my presses easily and accurately. However, my problem is that I can see the touch sensors even when the screen is turned on... I see small green-coloured dots, in a regular grid, specially when I have a white background. Annoying, but I think I can live with it... Better than send it to the service and wait a long time, with the risk of getting a new screen which may have dead pixels (I don't have any now).
Thanks for your replies everyone, makes me feel better about not having my Touch HD over the weekend. I pick up my replacement tomorrow and I think I'm suffering from withdrawal already.
Is anyone else having problems with their touch screen?
It will occasionally become unresponsive, and other times will just start 'clicking' repeatedly in random spots.
I find myself having to turn the power off and on (via the button, not a hard power cycle) to fix the issue. Its starting to get annoying.
Anyone else?
Yes, I am getting the same thing but I've found that if I just turn the screen off and then back on it fixes the problem. I don't need to reboot.
You think this would warrant an exchange? or is it just how its going to be?
I've put several hours on mine, but haven't experienced this issue. I don't know, if this happened to me more than once, I probably would exchange it.
It was happening to me all the time. I had to get a screen protector and haven't happened since.

Very good "solution" to what should be an obvious problem. The Nook Color has a *capacitive* touch-screen. If you get "junk/gunk" on the screen, it's gonna cause you issues. I find this to be the case while holding my NC and playing Flight Director for a while. The issue: My hands become sweaty and as a result of the slight film of sweat/oil on the screen, the NC's ability to measure the capacitive changes on the screen (and react appropriately to them) is compromised.
Keep your screen clean and you won't have this issue.
Note: after you wipe the screen down (damp cloth, etc), you will need to click the power button and go the lock screen and then back into the NC before it works right directly after cleaning the screen. The dampness of the cleaning cloth throws up the calibration enough to cause very strange things. My experience with "correcting" this issue tells me that in some way, the NC is recalibrating itself when you go to the lock screen.
johnopsec, this has been my experience as well. After cleaning the screen from finger-jam i don't get the phantom clicks. I also noticed that because I live in a very humid climate (Florida panhandle) there will be a thin moisture layer buildup sometimes and it really helps to wipe this off. I also have an incredible that does not have this problem but it has a screen protector which, I am guessing (and as gigadigit expressed), fixes the problem. Just make sure the screen is clean and dry before applying!
screen response
Also,
If you are holding the side of the case by the screen this throws off the touchscreen, I was having the issue where it would be clicking and multiple letter inputs when typing.
Also when it is laying flat and you have the power cord plugged in you may get multi letter inputs.
The trick, hold it by the back not the sides.
and if you have it plugged in and need to type don't leave it laying flat.
I have experienced this problem and loosely seen it correlated with moist fingers.
no moist fingers here and on my 2nd nc. this ones starting to have the ghost touches too.
My Nook Color started acting up after paying levels 3-4 to 3-6 of Angry Birds. I'm not sure if Angry Birds caused the issue or not as I haven't gotten it to do it in another app. I'm running 1.4.2. Doing a lock and unlock fixes the problem until it returns.
I managed to get Phone Tester to run after it got into this state. I made a video of it using a crappy webcam. There's a stuck finger in the corner.

Touch Screen issues while unit is plugged in..
It seems I have read on some forums that some people have screen issues.
Personally I didn't experience this until I tried to use my NC while plugged into it's wall charger.. It seems to act as if it has a grounding issue, which is not the case when the unit is unplugged.
So when you are running your multitouch or touch tests, do it without the unit plugged in..

I have had the same problem with my touch screen. I have the nexus live wallpaper and whenever you touch the screen it sends off the animation. Well sometimes it just goes non stop and sometimes opens up the window where you can apply a widget. I guess the most practical solution would be a screen protector but if not ill restore it and send it off to B&N
There's a small little app in the market named "Nook Screen Recalibrate" this app is super simple and easy to use. I hope this helps
https://market.android.com/details?id=com.assid.android.nookrecalibrate&feature=search_result
Here is the issue I have...
Right is the N button side. Just a reference point for this.
Reboot the Nook (I use CM7).
Bring up the keyboard
Touch Q in the center - you get W.
Touch Q on the right - you get W
Touch Q on the left - might get Q but you usually get W.
Recalibrate using the Nook Screen Calibration (above).
Q now gives Q unless you press on the right side of the key. I also notice I still have to hit the back arrow more to the left or I bring up the keyboard.
I've learned to live with it, but the left side of the touchscreen is slightly off and you have to touch to the left side of any object on the last 1".

yeah, for me it's the edge of the screen along the right side. it's less sensitive then the rest of the screen. I found that calibrating 2-3 times really works best.
There's also a fix in the nookwiki, but i can't get my adb to work on my laptop, I think its the drivers.
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen
What is the left and right side?
I should have said that left is the side opposite the N button.
I downloaded Multi-Touch Screen from the market and I can see part of the problem is the angle of my finger. Straight on it's better.
Nook Color Touch Screen Problem
Having similar problem as described, after two years. Extended warranty expired ... two weeks ago (of course).
Tried cleaning screen, no help. Have not tried screen saver yet, but will.
In the meantime, I notice the comments about touching the sides, and I noted that as well.
Is it possible that this could be helped by opening it up and re-seating the case? Has anybody tried this?
