Hello all
I am experiencing some really strange behaviour from my S-Pen. I cannot tell if it's ROM related, Kernel related, or Screen protector related.
Basically what happens is the screen registers an S-Pen touch, when the S-pen is NOT touching the screen. I seems like there is this hot spot about 5mm above the screen where if the pen hovers in this space, the phone thinks I'm actually touching with the pen.
This is obviously very annoying, because if I use the pen, and move around the screen without touching, the phone thinks I'm dragging my pen across the screen
Some info about my phone:
GT-N7000
Paranoid Android ROM 2.1
HydraKernel 4.2
A cheap clear screen protector (CYGNET brand)
Almost all these things happened at the same time, so I cannot tell who is the culprit.
Anyone else experiencing similar behaviour?
This is a common behaviour when you use your phone while lying down.
It registers the touch in about 3 mm gap most of the times.
This is not linked to any specific kernel or Rom.

The spen puts out a magnetic field that's picked up as touch on the screen, so above poster is correct, it's normal behaviour. If you're concerned that it's off placement, there's a calibration app in the Play Store, quite expensive I think, but effective as there are no samsung alternatives...

Thanks for the reply
It happens regardless of me lying down or sitting up. I can't remember that it was like this when I got the phone. If its normal, it's really bad from samsung, as the spen is useless to me.
As I move the tip toward the screen, about 3-5mm away a touch is briefly registered. Then nothing untill the tip makes contact with the screen where another touch is recognized. The "floating" touch registers almost no pressure, however.
The effect of this is when I write with the pen, it looks like I attempted cursive writing with a pen that's semi dried up.
It also makes playing abgry birds impossible with the spen, as now the moment I release the pen to fire a bird, a second touch is regognized when the pen hovers in that hot zone, which will cause all the special birds to perform their special acts way premature.
This can'nt be normal, can it?

My nook color is running a custom rom. I've used several roms and my touch screen is always very inaccurate. When I touch the screen, it registers the touch a little to the side of where I touch. It gets very annoying and really hampers the usefulness of this otherwise fine tablet.
Does anyone else have this problem? Does anyone else have a hacked nook with a good and accurate screen? Is there a fix? Should I bother getting it repaired?
Search the market for nook color screen calibration app that usually fixes any issues for me

I've tried it. It doesn't help me. It makes the screen more sensitive to the point where it registers clicks when my finger hovers a half inch off of the screen. It also makes it more prone to fantom touches.
You probably need to clean your screen

First thing is to thoroughly clean the screen as has already been mentioned. The next thing I would suggest is to get a screen protector as it seems to help a great deal with phantom touches. Also try running nook screen recalibrate (with the aformentioned screen protector) and disconnected from the charger.
The nook screen is really sensitive while charging.
If these suggestions do not help, perhaps you should take the nook in to B&N and have it looked at for possible replacement.

Either i am going mad since ICS leak has come out or the s-pen can highlight things on the sceen with out touching it?
I tried it out on this forum and if you hover over a thread with the tip of the s-pen about 1-2mm off it will highlight the thread.
i am 99% sure it isnt makeing conact, is there a function or purpose for this?
No idea but i noticed that also on the ics rom.

I am on the same boat. Hope the final ICS releases soon.
I dont know if this affects all phones/pens/firmwares but if I use diceplayer and hover the pen tip at 2-3mm away from the screen it repeatedly registers a screen tap.
same here mine is running 2.3.6
I've tried this before (on gingerbread) and it keeps the device awake in S-memo (maybe outside of it as well, haven't tried it.). But the reason is because the pen is by Wacom and if you've used a wacom digitizer before on a pc you would notice that you can move the pointer around the screen without touching the screen.
The pen is powered wirelessly by a substrate (I believe above the screen), and transmits its location. Now obviously they didn't enable the pointer to show on Android, but it seems like it is being registered as coming into the screen's activation range.
I had same problem before.i change the new from samsung till now no problem.
all the wacom pens actually work like this, the only difference there is that you can't only "move the mouse" so any input registers as a click.
it's probably not fixable outside of a driver update from samsung :x
This is a very useful feature: it's a visual display of what you're pointing at while hovering over the screen, no actual input is given...
If you hold the pen over a link in a browser, you can see the link getting highlighted before you select it...

curios, alls ICS leaks dont support S-Pen yet.
And that issue doing inputs without touching the screen is due to a faulty S-Pen.
Replace it, its a warranty issue.
The pen have to be, not only touch sensitive, but pressure sensitive too.
If you press more down, the line you draw got thicker.
im on ics chinese leak but no problem with s pen

My s-pen seems to work fine i have done some drawing and the pressure sensitive feature works?
How would i go about claiming for the s-pen on warrenty if im running ics, would the want the phone back?
Does anybody else find the S.pen of the SGN really bad??.. when it comes to drawing some stuff..? Any remedy for that?
Sent from my GT-N7000 using XDA App
i don't draw but i do annotate quite a lot, and it feels like the calibration is a bit off. what in particular about it is your concern?
Like, the place where i point the pen and the place where it writes is not the same,the location where it writes is a little bit to the upper left( not precise)... and its also has a latency after writing...
Its not a very big problem for me just a little critic...

I've used five s-pens so far, and two of them were significantly worse than the other three. Good news is that the problem is most likely with the pen itself and not with the Note!
Try getting a different pen (e.g. there is an official Samsung holder that comes with another pen). For the offset problem, try to switch from right to left to right... several times --- sometimes that helps to make the offset more reasonable. Also experiment with the angle of the Note as you write, often that makes a difference too.
Just my two cents...
The reason why it seems a bit of is done on purpose.
You notice this when you change your writing hand in the settings.
When it's set to your right hand, the drawing is slightly left of your pen. With the left hand it's the other way around.
This is done so you can see what you are drawing/writing and your hand is not in the way.
I know it sucks, but Samsung made it this way.

This is true, but some pens have larger offset than the others. I think some of them have sensitive elements inside aligned better. And actually this works rather nicely if the offset is reasonable, at least for me. Takes a bit of practice, but feels quite natural after a while... if you think about it, some offset is appropriate, since there are three surfaces at different depths: the writing surface, the "displaying" surface, and the actual surface which is sensitive to the pen's movements (this one is quite deep, it's behind the screen, not in front of it)...
Try different pens before giving up
Yeah the calibration is not exact to the point. When I'm writing words normally I'm not really affected, only when it comes to drawing in slow motions, the placement is off and it's frustrating for drawing little details.
However, I managed to dig out an old stylus which came with my ancient fujitsu tablet PC and it's calibrated perfectly.
I've noticed that the angle to which I hold the s-pen to the surface makes a difference in percieved accuracy.
This app has worked for me:

It will run without root, kinda, but you'll be getting something like this on the unlock:
"ERROR: IOException! No ROOT permissions?"

With the Fujitsu pen, does it have calibration issues or extra lines if you write on it upside down, like if you were lying on your back? My biggest pet peeve with this phone is that I can only use the pen if I'm sitting upright and holding the pen just so, otherwise calibration is way off and a lot of unintended lines appear.

I've noticed this too. It's most apparent to me when I set my phone on a table, holding the pen by it's very end. Touching the screen with the point and changing the angle of the pen relative to the screen--without moving the tip of the pen;s position at all--you can see the cursor move with the angle of the pen, even though the tip stays in one place.
The best way to fix this, in my mind, is for Wacom to do on this phone what they do for a lot of their tablets--have a little dot show up on the screen when you hover your pen, so you know where you'll be drawing.

This is a damn good idea right here. Someone should forward this to Samsung before they roll out the ICS update.

Well you guys said it all... drawing details,drawing slowly, lots of unwanted lines appear...etc...
I see, so its most likely caused by the pen rather than the note itself... ill give the app(touchscreentune) a try..thanks.

Anyone is experiencing this tipe of problem?
When I press (very softly) the border of my phone I see a liquid crystal wave like when you press with a finger on a computer monitor.
This problem is localized only in one spot: on the left side about two centimeters from the bottom.
I.e. Put your finger just above the navigation bar or slightly higher and press to the right on the glass stripe of the side. Of course this is difficult to see on white background so maybe try on a coloured background.
Can this be eligible for a repair under warranty or this is not a real problem?
Thanks for your feedback!

Ok thanks, just bad construction i like very much this phone, just wanted to be sure it isn't only my problem

So every computer monitor is badly constructed? Try dropping a computer monitor in the floor outside and see how well that works.
The Sony reportedly uses a softer glass so that it is more flexible and bends instead of simply breaking.
Have to say this is the most sturdy phone I've owned. Stop pressing the screen in lol.
also they dont use the technology the other LCD manufacturerers use thats the air gap between LCD and the glass , thats the reason u get precision

I think you can catch the difference between the use u have with a phone and the use you have with a computer monitor, right? Or you keep pressing on your monitor hoping this will evolve to touchscreen?

my last question is: this "waves" damage the screen/lcd or whatever else or i just don't have to worry about them?
When my phone is laying flat on a table the touch sensitivity is very poor, at least around the edges. I can't pull down the notification bar and the nav bar is near unresponsive. It almost feels like it's some sort of feature to prevent accidental touches, if you know what I mean. Has anyone else experienced this? There is no issue when holding it normally in my hand.

I just tried it...yeah, it happens on mine as well. I guess it has to do with the curved back no biggie. I normally lay it down on my wallet with Skip inside. So I have never even noticed this
Yeah, not really much of a concern for me either. Just curious if others had experienced it or if anyone knew why it happened. Interesting idea with the skip/wallet setup.

Good to know it's not just mine. Did you have a screen protector on when you tried this?

Yes, actually. I have the thick shock protection sold on the Motorola site. I have been meaning to test it without but have been waiting to get a new protector to replace it however. I really don't like this protector and hope the touch sensitivity gets better once it's gone. I have just been lazy in looking for a new one.
I cannot detect any loss in sensitivity when my phone is laying on my desk. I am not using a screen protector at all.

No problems pulling down the notification bar? Also can you try installing the following app and drawing lines from the center of the screen all the way up to the top of the screen? Does the line go all the way up or does it end slightly before the edge of the touchscreen?

Yep noticed this as well. Mainly on the home button. Back and recents seem responsive enough, but if it's laying on my desk or floor, home is almost non-existent. Gets to be pretty frustrating.

No problem with the notification bar at all. I tried it all along the top, it works perfect every time, fast or slow movement makes no difference.
Might try the app later but I just gave it another good test and it performed perfectly, even if I barely touch the screen.
Yeah... Mine is fine too. No screen protector.

Just tried it on mine with no screen protector and I am getting the same as the OP.
It's funny because usually I sit it flat while I am on the couch - must be the soft surface and the curved back which means it works fine, but you're right on the hard table surface it's noticeable.
