Hi,
on a rooted Galaxy Note 10.1 with Android 4.1.2, I get this quite weird behavior in S Note and all apps that use the SPen.
Sketching with the SPen shows a couple of relatively large insensitive areas on the screen, while using the finger the areas are "fillable".
The two behaviors are shown in the pictures.
Any clue ?
Thanks in advance
Do you have it in a case that has magnets in it? Magnets can screw up the wacom sensor causing this issue...

This is right what it is !!!!!!!
I have a case which has three magnets right below that area, and one not far from the other edge.
Removing the tablet from the case sorts it out.
So, I've removed just the center one, which resolves the issue 90%.
Thanks so much !!!
No problem, we're all here to help ....

while I play with my girlfriend smart cover with my note 10.1
i find out while screen off ,if take out the s-pen will be screen on
and accidentally find that,when the magnet touch the area which hide the s-pen,will make it screen on
I'm thinking of how to make it work with opening the cover,and a question,would it break the function of the spen

I'm guessing you're in Asia. The Book Cover isn't being released in the EU and US until later this month so I doubt there will be a lot of people that can help you.

yes, i'm form HK ,but don't have the book cover or other case either
just use the ipad cover to find it out,or using a magnet

The "official" Book Cover a lot of us are waiting for has magnets in it too. So I'm guessing it's not the magnet itself but where it's hitting your Note.
I just took a small neodymium magnet (very strong) and ran it over the entire front, back and around the edges of my Note 10 and nada. Didn't wake it up. It did, however, stick to the speaker magnets.

Was you S-pen in its slot at the time? If so, maybe take it out then try again, just to see what happens?
The touchscreen acts weird just above the samsung logo when i'm using the s-pen. it's not accurate at alle (the line is drawn a cm from the point of the stylus) and movements are way bigger than what i'm actually doing with the s-pen. Is this only on my tablet or is it a general issue?

Are you charging your tablet? Because if I remember correctly, some reported that when charging GN it may have some problems with touch screen.

No, not charging. Just under the front facing camera i have the same problem. The problem is the magnet in the case i'm using!! The problem disappears when the case is not attached. This sucks!

Yes. Magnets are not good with a Wacom digitizer.
A Wacom digitizer acts by generating a small variable electromagnetic field. It induces a small AC current in the little LC circuit in the pen (that needs not be alimented). This AC current is then detected by the Wacom digitizer (present in the Note's screen) when it switches to "receiving" mode (it switches from send to receive mode many times per second).
In this way the Note knows where the pen is located.
Any magnet nearby the screen can disturb the signal sent and received.
It's not really a flaw in the Note's hardware or software but something that is inherent in how the Wacom digitizer works.
Simple solution: it's better to avoid cases with magnets.
(and that also explains why Samsung original cases don't have magnets... correct me if I'm wrong)

I bought the case of ebay, it's very good, but the magnets are not a good idea indeed. I'll try some shielding, but that will be quite difficult.
Does anyone have this problem? I think it's only on the newer devices because my old Note 10.1 didn't have this issue. In addition to being a tight fit in the slot, the pressure sensitivity didn't work very well until I sent it back to Samsung for them to adjust the potentiometer. The pressure sensitivity now works great but it's still a tight fit in the slot.
This is affecting the S Pen sensitivity! The lines I draw are skipping instead of having continuous pressure. It was the same problem which was the reason I sent my S Pen to Samsung to get the potentiometer tweaked. After it was fixed, the S Pen worked perfectly. The force required to remove the S Pen from its slot must've messed with the nib. It's happening again!

Hi,
So far I've been through two keyboard cases for my Galaxy Note. The last one I just got today was great until I tried using the S-pen while the case was on. There are certain regions where there a magnet in the case causes the S-pen to become unpredictable. I'm kind of surprised as this case was designed specifically for the Note 10.1, but it's as if it was never tested.
I have searched online and can't seem to find a bluetooth keyboard book/folio type case for the Note that is magnet free. Can anyone provide any useful product suggestions for me?
As an update, I was able to narrow down the problem to two specific offending magnets in the case. Interestingly enough in those areas the material was thin enough that I could scratch away at it with a scissor and pluck out the two small circular disc magnets. Later on I suppose I could cover up the "surgery" spots with some velcro, but the location is not too conspicuous and now the spen is working appropriately. Problem solved!
hi ..just got my note 12.2 from pc world .. was actually undercutting amazon so couldn't resist
anyway ... the bottom of the screen about 3 inches in when you try to draw a straight line you get a curved line and in two directions so its almost forming a circle of some kind .. ive just tested my stylus and my girlfriends edge sylus and mine of my note and it is doing the same thing .. however when you use your finger the curving of the lines does not happen ... so its obviously stylus related at this point of the screen only
has anyone run into this problem and do they know how to fix it .... or do i need to take this tablet back to the retailer as faulty ?? does something need to be calibrated ?? i havent seen an option to calibrate
picture attached of what its doing
Are you're using a case that has a magnet? If the answer is yes, take it off.
The Spen uses a magnetic sensor. Anything with a magnet in it will interfere with the pen.

Thank you for your information on that one .. i take exposure would not cause any permanent damage as lots of cases are magnetic ??
of course thats annoying as i bought the case to protect the note .. from possible drop damage and now i cant really use it much when drawing on the note now ... this one has a bluetooth keyboard so was quite nice from amazon
anyway thanks a lot there my girlfriend and i were panicking .. lol
the magnets are a top flap magnet to keep the case shut with the keyboard and i think one at the back that holds the back stand in place
What case is it exactly?
