Dear developers,
This is my first post in xda and I apologize in advance if I posted this question in the wrong place.
I searched a lot in the internet to find a way to allow me to use the digitizer stylus (the same one available in Galaxy Note) on the screen of my galaxy tab 7 plus, but unfortunately with no luck.
The digitizer stylus is available in the market as a replacement of lost or damaged Galaxy Note stylus. Therefore, the stylus is not an issue. I really believe that the stylus should work on any capacitive touch screen of any android tablet if we succeed in extracting the Wacom driver, or software, from a Galaxy Note and install it to the tab.
I searched in Wacom website, but found drivers for windows and Mac only, nothing for android.
I also tried to locate the Wacom in Galaxy Note, with no success :'(
I hope anyone tried such thing and looking for someone to share the experience.
Thanks!

If the Galaxy Note is anything like the conventional Wacom tablets, the hardware is primarily in the phone/tablet itself and not in the pen. If this is the case, your idea will not work.
You can, however, buy many styluses (styli?) that support capacitive touchscreens.
This is actual Wacom technology
Hello, you cannot use the S-Pen on non-Wacom screens because the stylus is not capacitive, but electromagnetic.
Using your finger, try pressing an UI element (like a widget, or a ListView item) so that you successfully select it. While the item is selected, slowly move the stylus down towards the screen. When it will be 1 cm away (or less) from the screen, the item you selected with your finger will get unselected. It is because the electromagnetic stylus has priority over your (“capacitive”) finger.
The fact that the stylus priority thing occurs even though the screen is not pressed with it, is a proof that the usual Wacom electromagnetic magic is in use in the Note.
I have the Galaxy Tab 2 7.0, rooted with 4.0.4, and have not had any problems with it for the most part.
I recently downloaded Sketchbook Express to see how well the tablet could handle drawing. It handles it very well with one exception: the closer you get to drawing at a 45* angle, the more wavy the lines get. If I quickly swipe in that direction, it straightens out, but the slower I go, the more pronounced the waves or zig zags get. This happens using any of my fingers, the $20 Rocketfish stylus, and the $30 Wacom Bamboo stylus. All attempted on a freshly cleaned screen. I've also tried different apps with the same result. This guy had the same issue, as have others from what research I could pull up, but outside of unhelpful answers of "it's your stylus" (it's not), they all seem to have given up on getting help.
I've tried these apps on my friend's Evo 4G 3D, running Android 4.0.3, and had the same issue. I then tried on my rooted Xperia Play running Android 2.3.3 Gingerbread, and did not have this issue. I'm not entirely convinced it's an OS version that's making the difference, but I'm not able to find much information about the screens these devices use outside of "capacitive touch". I did learn that these screens use the corners to determine the location of input being received, so maybe moving directly in the direction of a corner is causing it to mess up?
Long story short, my questions are thus: is there any way to fix, calibrate, or compensate for this issue? Is it the screen, a hardware issue, or something else? Is there anything I can do?
Thanks for your time.

The problem is the digitizer. It's cheap. I think all of the g tabs have this issue. Mine is terrible drawing diagonal lines and even scrolling in landscape mode is choppy. Only way around it from what I can tell is to apply more finger surface area. That seems to fix it. But since you're using a stylus that's not possible. If you find a solution to calibrate the digitizer, please let me know!
I have the same exact problem and the same exact request. There must be some option to increase sensitivity to at least minimize this effect. It's the only flaw I can find on this otherwise wonderful device.
And honestly, for the prize it cost, I would expect this not to exist. But... I have it now and would like to be able to use it in it's full extent and power.
dammit
Nice to know I'm not the only one who notice that, but it's crazy how my finger seems preciser than my pen and even more, that in my Galaxy S the pen works perfectly. I was so happy to use some drawing apps on the tab but when I tried...
I tried in my Tab 7 2, then I'll try on my uncle's 10.1 just to check.
hello all,
just to report the same issue. i have same problem with my samsung galaxy tab 2 7" like you all here. i get this problem since the first time i bought it (about a month ago). drawing the lines and reading in landscape mode is choppy :crying: same as MrHyde03 said. i have been tested my cousin's tablet to draw diagonal line for comparison, he has galaxy tab p1000. and the line result i get, though his tab has wavy line too, but mine has more wavy line than his tablet. i didn't noticed his tablet has so wavy line, just a little. i did it with my finger.
i hope this issue can be fixed later.
could be a solution
I don't know if it's just for marketing or what, but maybe the original Samsung stylus is better for these screens.
I wish someone could certify this...
I bave The Same Problem... Vawy diagonal and arcs. The same pens and fingers works fine on my Asus TF 101...

Hi guys, I have the same problem. Horrible response when i draw with a (cheap) stylus and perfect when i do it with my fingers. Has anyone tried adonit jot pro or Dagi ??? Maybe they increase the contact area and it solves the problem. If so, please tell us!!!
Thanks for reading and waiting for a solution.
I know this is an old post, but I can't just abandon my own thread! I've done quite a bit of research on this since making this post, and sadly, it's the way the screen is. Strange that my Xperia Play and Galaxy S3 phones can do this, but the Tab 2 was given such a cheap screen. I ended up selling it and putting the money towards a Note 10.1 with S-pen, which works as I would expect it to.
Hi,
I've found on my Note 10.1 that the accuracy of the S-Pen gets worse near the edges of the display. At the very edges it's off by about 1 mm or slightly more. I can't say it's really caused any problems but I'm wondering if this is normal and if there's any method to better calibrate it?
I've been having the same issue, or at least I noticed it recently...
Does anyone know anything about this problem?
This has been bothering me a lot lately, especially since i use my Note for note taking. Bump in case someone knows the solution.

Here's the response from Samsung support:
Thank you for contacting Samsung Customer Care.
We understand that while using the S pen near edges it looses accuracy.
We are sorry to hear that.
Please try replacing the S pen tip to isolate and fix the issue.
It is not possible to calibrate the digitizer.
Thank you for contacting Samsung.
Kind regards,
Steve

I''''ve found the S-Pen (as viewed by enabling the hovering pointer) loses accuracy the closer to the edge of the screen the pen is used. At the edges it is off by at least 1 mm. About 1 cm in from the edges the accuracy is good.
Is this a defect in my unit or are they all like this? is there any way to recalibrate the digitizer to improve accuracy?

I tried changing the tip with both types of tips supplied with the tablet and as expected it had no effect. Note, also, how utterly useless Samsung email support is. The only way to reply is through a link which sends you to a contact form to submit a new email from scratch. There's no incident number or any way to establish continuity.
In any case, I happened to be at a Microsoft store yesterday and played a bit with Samsung's ACTIV (sp?) pro Windows 8 tablet which has the same s-pen as the Note 10.1. What I noticed immediately is it behaves exactly like my tablet: the digitizer loses accuracy both when tilting the pen and especially when the pen is near the edges of the display. The amount of inaccuracy is just about the same too, about 1 mm near the edge.
So I suspect this may be a limitation of the technology or at least the technology as it's being used by Samsung (I'm surprised Wacom's stuff is not more accurate). I'd be particularly interested if anyone is NOT seeing this.
It also seems silly that the display cannot be recalibrated or the driver does not support remapping. This seems like something that should be pretty easy to implement.
On the positive side, I can't say that I've experienced any real accuracy problems when in actual use. Probably I don't tend to write so close to the edge where it might be an issue. It's more an annoyance that the cursor doesn't quite match the tip. It's actually less annoying than having my hand trigger s-note's zoom or the notification drawer every time I try to write something.
Too bad, samsung support is horrible. For me this problem is pretty annoying since I tend to write until the VERY edge (just like I do in real paper), so I guess I'll have to change my habits lol.
P.S: It's good to know that is not my faulty tablet, but something "normal" in wacom devices...

Yes, it is annoying. I wonder if there's any dev we can convince to write a remapping layer to fix this issue.

I wouldn't expect much help from a company that hires people who don't know the difference between "loses" and "looses". That's sad.

Hi to all. I am having a note 2, it has the same s pen as all the note series... i had that problem but it fixed when i did update! Try to go on developers options and check 'show pointer location' to check if the problem is the spen or the software.
I also notices that when used near the camera there is a great loss of accuracy .... and good to know that's not hte fault of my Note:good:

Mine just works fine, even on the ledges! Sometimes, but sometimes when the accelerometer is uncalibrated the S-Pen just stop responding well. I calibrate the accelerometer using this game https://play.google.com/store/apps/details?id=com.fgol.HungrySharkEvolution Just go on Options/Change to tilt control(If necessary)/Calibrate
It worked for me!

Thanks for trying to help .... the slight offset near the edges is no problem for me but i had a relatively bigger offset near the top (near the cameras) but that appeared to be due to the magnetic part in the book cover i had what an idiot .. i thought the camera had magnetic parts that do this and forgot the magnet of my book cover
So now what i really have is the offset near the edges
For me it's not an overall offset issue but just near the edges where it makes taking notes, sketching particularly difficult. It's very frustrating that these tablets aren't better calibrated out of box and provide no option for calibration. I'd be very surprised if this couldn't be fixed through software but would probably require support through the driver.
The other issue I have is that the drawing point only visually aligns with the tip of the pen when the pen is 90 degree from the tablet and you're looking straight down at it. Provided you hold the pen at a relatively steep angle and you angle the tablet so you're looking mostly down at it (say on your knee or a tilted stand) it's not bad. But once you deviate from that, say by putting the tablet flat on a table in front of you so you're looking at down at around 30 degrees, the deviation from where the tip appear to be and where the drawing point is becomes significant. I find this very frustrating. While I still prefer the s-pen to a passive capacitive pen, the fact I can't draw where I think I'm drawing makes it hard to work with. I've been using the tablet as my primary note taking device but I'm getting frustrated enough that I may go back to pen and paper and scanning.
It's probably not possible to fix this issue without hardware changes. Although multiple calibration profiles might reduce the effect.
I guess I'll have to wait for better hardware before I can finally live a paperless life...

That was it for me. The case was causing that. When I read your post I realized that my case has a keyboard and you can remove it. It stays in place with a magnet. So I removed it and it works as expected. so now I know to get it on the edges it's that. Thanks:good:
I recently purchased a used note 10.1, and I must be doing something wrong. I tried searching for this question, but I could not find quite the same thing.
I got the note mostly because I have always wanted to have a tablet with a pressure sensitive stylus (s-pen), but they were out of my price range until recently.
I want to be able to put down a very thin line, and then be able to bring it up to a thicker line. I CAN do this in papyrus, beautifully and perfectly. But I cannot seem to do it to nearly the same quality in S Note, on the exact same tablet, in the tablet's native note software (the software the stylus was made to be used for).
I can put down a far more delicate line in papyrus. But with the exact same pressure, I lose the line entirely in S Note, as if I am not applying enough pressure to register the line. But the pressure is the same.
My question is...why is this? Am I doing something wrong? I want to be able to use S Note in all it's glory, with all of the cool integrative features, but I want the pen to perform as good as papyrus. I am aware that I can physically adjust the sensitivity of the pen by taking the button off, but then my notes would look bad in papyrus. Do I need to pull apart the s-pen and adjust the sensitivity for each individual program?
HELP! Very irritated by this.
Each app has it's own pressure sensitivity and filter settings. With Lecturenotes you can edit some of those settings.
About your issue, maybe buy another stylus and adjust it for Snote only?
Is there a root app that manages all that? A separate s-pen for different apps is an expensive choice.

So I adjusted the pen with the instructions so that it is just less then marking when hovering, as soon as the pen makes contact it begins to mark, but then the slightest touch of the s-pen makes a comparably big fat line. I made a video showing the difference.
http://youtu.be/3ZaIuEkIBR4
What am I doing wrong? Does S-note just suck for everyone? Or just me?
So it turns out that the snote "pen" simply does not exhibit pressure sensitively. Pencil does. So I guess I'm stuck with a fuzzy line if I want pressure sensitivity. I wish I could download more writing implements. A gel tip or a calligraphy ps pen would be amazing. Oh well.

Have you tried OneNote? Handwritting was added in the last update and it does what you want, nice pressure sensitivity writting.
Just curious if anyone has tried this out yet? My DirectStylus 2 works if enough (light) pressure is applied to the screen and goes beyond what I had assumed. Seeing as this is a capacitive touchscreen like most modern devices I'd like to know if anyone else have had luck with the mentioned tools in the thread title. A Wacom Pen should suffice as well.
I used SketchBook for my test which is free app for basic tasks in case anyone feels like trying out. The key seems to be a thin digitizer as my Moto X 2014 barely goes by simple strokes or even taps (thicker digitizer/glass = more pressure needed).
im not 100% but you will find that a s pen type device would not work you need sensor behind the screen for that like the note series, you would need a stylus which simulates the static electricity inside people for the stylus to work which I believe there are some clunky types available but im sure someone will be able to clarify this for you
