I haven't seen this addressed here, but is anyone else experiencing flakey Nook Color touch screen behavior?
Sometimes it seems like there are random "ghost" touch/taps to the screen. It's very annoying, but power cycling or just locking and unlocking the device (by pressing power and getting back to lock screen) seems to fix it.
Here's a YouTube video which appears pretty close to what I'm experiencing:

Any insight would be appreciated. I've only had the Nook Color for 3-4 days, so if it is a problem specifically with my unit, I'm thinking I may need to exchange it.
I seem to be having the same problem, too. I DO hope it's the software and not the digitizer, though.
Oh, look further down this forum section. There's another thread about it and it has a recalibration procedure.
Its definitely the software. I was having issues and recalibrated and it works a lot better now.
I almost think b&n screwed up the edges on purpose to make page turning easier... seemed to be black holes around the screen edges and those seem to be gone now. Tested with a touch test app and it works correctly now (although I didn't test before the calibration so I can't confirm that didnt work fine before the calibration...)

Additionally, I went ahead and sent back to factory defaults for the 1.0.1 update and I tested the screen before recalibrating.
Exactly as I thought, the edges of the screen are calibrated so that when you get near the edge of the screen, it essentially "rolls" all the way to the edge... so there's a very strong "gravity effect" near the edges of the screen until you run the reconfiguration steps as posted above.
Does anyone know of a way to remove the proximity sensor drivers or shut it off completely my screen just goes black during a call and i need to use the keypad during calls i have tried all the proximity apps on market and it has no effect, have tried calibration etc odin firmware updates to the point i killed my phone just got it back from repair and was told it needs a new chip to rectify the problem.
I have spent weeks going through forums for a solution and i know on my brothers sgs 2 it has a setting in the menu to turn it off.
This seems to be a common problem with no resolve so im looking for someone to resolve this problem and make alot of people happy.
We all no As these phones age this will be more and more common.
Techies get ur teeth into this or even software writers make An app n earn some cash,
This would b a great ego booster for someone to say i solved that when no one in the world could.
Thanks...........looney

Mh? Why not pressing the home button during call.
Screen is enabled then...
Anyway MIUI got this option to switch it off.
Don't know if this setting is available in Stock ROMs.
screen should go back on when you move your head out of the ~5cm sensor radious. if it is not happening there are two possibilities:
- something wrong with firmware -> reflash phone with pure unrooted samsung firmware and check if problem persist
- someting is wrong with proximity sensor -> use warranty and send it to service center with proper description of the problem
Thanks for the replys the home button won't work as the proxy is up the spout had it checked the chip is blown, when u press the home key won't work as the phone is trying to find the proxy then eventualy it will crash and force close.
No software update will do it as its a hardware fault unless it turns it off so will have a look at the one you suggested.
There is def a stock version but i fear it is only on the s2 to turn blank screen off il check my bro's firmware, till then keep the suggestions coming in thanks....

Here is a possible solution. Check the + 3.7 volts at this point, if there is no tension, then feed it thither with a jumper

Thanks for the tip. Where can i get 3.7 V from? (which part of the MB)? Is there a way of hardware disabling the sensor? the software testers report 0.7 mA leakage on a sensor (which is faulty anyways)

You can do this:
Every couple of days I have a problem with the screen becoming VERY unresponsive. It seems to affect the whole screen and requires touching characters on the keyboard, web buttons, app icons, etc. multiple times before the touch is registered. The problem persists until I reboot the device.
I haven't rooted yet or otherwise modded it at all, but maybe I have a poorly optimized app running? Haven't tried to capture a logcat yet either (and frankly wouldn't know what I was looking at).
Has anyone else experienced something like this?
Thanks!

Looks like mine is suffering something similar to the problems discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1779652
I also have this issue. Was able to reproduce with multi touch tester apps. When I cross axis the touch points freak out. I think it's a grounding issue. If I touch the headphone jack or have headphones in the issue goes away. Called in a RMA request yesterday. Hope this issue isn't present in the next device.

Hi,
I've started to notice that my spen doesn't seem to be working anymore. I never want first day that it is very difficult to use the pen for taking notes, drawing, etc. Wasn't dropped or anything like that, it just seems to of degraded over time.
I've tried it on stock market rom and cm9 and having the same problem. When I checked the pen on stock rom, by showing pen location on screen, it shows it (both when touching and above the screen), so it is being sensed.
Finger touch works fine so I think the digitizer works well. I also have a screen protector on, but I've tried taking it off and having the same issue.
Does anyone have the same problem?
Also, is there a way of increasing the sensitivity to the pen to see if that improves the problem.
Cheers,

I guess it must be due to minir wear-n-tear . You may try to OPEN and RESET at respective parts of your SPen.
I had posted a thread titled "Anatomy of SPen" on this forum, which might help you understand how to open and reset it.
Hey guys,
Thought I'd post this here and keep you guys updated on further developments.
I live in the Netherlands and bought a 32GB version at Dixons at the 13th of November 2012
I had found the touchscreen a bit unresponsive sometimes in the past.
But couldn't really find out why it was acting up. I finally isolated the issue.
It is exactly the same as this guys vid:
(Thanks for the vid injahnet)
Together with a little backlight bleeding, I decided to send for repair.
(The problem persisted after a factory reset, no other apps were open when testing.)
I went back to Dixons and showed the problem to the Dixons dude.
He acknowledged there was an issue and sent it for repairs or replacement.
Due to the holidays this can take some time. Maybe even next year
I was about to open my tablet for a look inside one of these days, boy am I glad I didn't do that yet
Anyway to get a good view on this issue globally, are there more people that have the same issue?
You could go to: Settings > Developer options > and then under "Input" you can enable Show touches. and try to to the same procedure as in the vid. (Thanks Peterk-1)
Or you could test with MultiTouchTester like Injahnet.
The weird thing is, my dad's N7 16GB does the same.
Update 17-12-2012: Please do not test while plugged in as the device will be grounded and the issue will not occur. (Thanks dad)
Feedback is really appreciated!
Please vote in the poll above!
Cheers,
Daan
I have zero problems with multitouch while using my Nexus 7. Working just fine, but you must disable any apps which interfere with gestures or it'll steal events.
Can't say I've ever used multitouch with the N7 laying on a random object however.
But sure, send it in for repair......... I'll keep using mine.
If anyone thinks they have multi touch problems then loading an app isn't required. Just go into Developer Options and under Input you have two options to display touch and track detail.

I've done a factory reset before I tested No apps are open except MultiTouchTester
It's in for repairs
Well... Over 200 views. And only 4 votes, which includes mine
Community feedback is failing hard.
Anyway, I'll keep you guys posted on the repaired Nexus.
At the moment of writing we know that three people are having this issue.
I know someone else with a nexus I'll check if he has the issue too.
Cheers,
Daan
Yes, i have this problem. And only while device is laying on the table.
Wow, this is bizarre, thanks for pointing it out. I can confirm it happens when it's laying on my pillow, and doesn't when I'm holding it.
Thanks for the vote guys.
By the way, it seems obvious that the Nexus should not be plugged in while testing.
However I cannot test this 'cause mine is at the shop
Would anyone be willing to test?
I'll add that in the original post (+ a mention of your name and a thank you of course))
Cheers,
Daan
Mine was unplugged while testing.

if the two touch-points got the same X or Y coordinate my nex7 does only detect one of them. i don't think this is an issue.

However, zooming in Google maps for example will become quite difficult
Anyone try and see if taping the ground pin on the wifi antenna fixes the issue? This seams like a grounding problem.

Exactly! I was also thinking of this.
Do people who have this issue also have the flickering issue!?

Just an FYI, I installed CM 10.1 with Trinty Seven. Now I get 10 touches on pretty much any surface.
I don't have a multitouch issue, but I do have an entire band on my screen which has stopped responding to touch at times. It all started when I let my tab shut down due to low battery. Initially, the Nexus 7 neither charged (when put on charging, obviously), nor did it boot up. After trying for several hours, somehow it started charging. And since then, sometimes certain areas of my touchscreen become unresponsive to touch. Since the band which is unresponsive is towards the upper part of the screen, using notifications becomes completely impossible. It keeps 'snapping back up' when I try to pull it down, cos while I am pulling it down, the notification tray encounters an unresponsive area, so it just goes back up. Called up Google and they will be sending a replacement device. All I am afraid about is that I have an 8gb version, and they would be sending an 8gb as well, so I hope it isn't refurbished or something, as Asus has stopped making the 8gig model.
I'm having an issue where the screen, ( mostly in a webpage or document,) starts moving up and down and zooming in and out without my input.

Just tested this out and yes, my device is doing it too. Interesting. No other issues like screen flicker (except the auto brightness bug in 4.2). My n7 is c9O

community feedback is not failing hard, more like you're just starting a new thread without bothering to search if issue/topic already exist.
this isn't new and there is no fix, that is just how the touchscreen function. the N7 isn't the only device to have this.

Must... not... feed... aaargh....
You are kinda missing the point of this thread.
It is to see how many people have this issue.
There is no thread capturing that in an easy way unless you want to count every post.
Now please tell your brain to start functioning again and leave this thread alone if you have nothing to add.
Asus Google Nexus 7 32GB touch death zone
Hi DaanJordaan,
Found out that my brand new N7 seems to have a similar "no touch zone" issue; an area the size of my little finger on the left lower part of my screen does not seem to react to touch! It interferes with typing the keyboard in portrait mode (no keyboard problems in up-side-down portrait mode).
When I use the Easylabs Multi Touch test I can see the dot changing color when I move over this area, doesn't happen anywhere else on the screen..
Using the developer tools (turning on the two options that allows to show touch/leave a trail of touch) it becomes even more clear that this area does not react to touch! I can "paint" lines around the "no touch zone" (it actually splits into 2 touch areas using one finger around the "death spot"), and the "no touch zone" reveals itself by not showing any trail/history line of touch..
Oh yes, and it does not matter if I lay the N7 on the table, or hold it in my hand, the issue is always there.
Therefore I returned the N7 back to the MediaMarkt, and they will send it in for repairs...
I've got a bad feeling about this | - )
I am curious to hear about experiences with your N7, once you have it back!
I'll report mine here, in three weeks or so (that's the outlook...).
Cheers!
