[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
My S-Spen went goofy with 4.4.2 as well (fully stock)

I am having similar stylus offset issues after 4.4.2 update. I am fully stock, and never had stylus offset issues. Crazy frustrating, and I actually opened a help case with Samsung, whose advice was to factory reset. Having never done one, I backed up via Kies, copied SDCard files, etc, but dang, what a bummer to go thru a factory reset and try to rebuild the tablet to have icons where I want them, apps, etc. Not to mention all of the local saved game progress that is gone. AND it did *nothing* to help the s-pen accuracy problems; I should have known better, but thought I'd give it a try. Samsung suggests sending it in for a tech to look at it, but not way I am doing that...I don't trust their level of support, to be quite honest.

So, I am equally interested in experiences that have gotten other users' SPens to start behaving. I have tried S-Note scribbling, but with vertical scrollbar, and menu stuff at the top and bottom of the screen, I surely cannot scribble the entire screen. I am also curious in more details on how anyone, using S-Note, got it to effect some positive change.

Thanks,

Mike

Now, after always staying stock, I am considering whether to use custom ROM or kernel; I saw the couple of posts about civx(sp?) ROMs making the s-pen work well again. So many questions on custom ROMs, though <sigh> but perhaps it's time to do some research and give it a shot.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
I have S Pen 4.4.2 issues, curious if our builds are the same?

I also have S-Pen issues, and have not been able to get S-Note to drive a fix. I am running stock 4.4.2.

Just for completeness and clarity sake, I wonder if it makes sense for any of us to compare versions/builds that are on our tablets? I assume we are all on the same, but who knows...

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] CCallahan:
Just keep in mind that not only does the framework require modification to fix the SPen accuracy but it is also in the kernel. Don't see how SNote can modify the kernel data and framework to fix. Not saying you don't see a big difference using the method you used, but have to wonder why it works for some and not others. Best option still is to root and install custom rom & kernel.

Just my $.02
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Spidey01:
I've found that (at least in INKredible) that it is much more noticible on portrait than landscape. Changing between them and back again seems to reduce the offset. I dunno why the orientation matters so much. Normally I use landscape.

Just wondering if anyone is still having the S-Pen precision issues on a Note 8 device. I know I am, it's off by 1-2mm. Samsung are proving unable to recreate or fix it, although they have replaced the screen and 'some internal components' (so they told me).
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
Yes, still having s-pen precision issues

My s-spen offset has remained ever since the latest Samsung-pushed 4.4.2 OS update. I have tried the calibration routines (use s-note) without any success. A real bummer since I did use this tablet for drawing, and now it's useless for that. I keep waiting in hopes that Samsung releases a 4.4.4 (or Lollipop, but doubt it) update, and maybe that will fix the issue.

I saw elsewhere on this thread that someone, after multiple tech support attempts and tablet returns to Samsung, finally got a 4.0.x tablet returned to them, and the s-pen was fine again. Either way, what a bummer/hassle.

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
You can do it through Snot, just have to be patient and careful to do the edges... I did it long ago and was one of the first to tell peeps here on the Note 8.0 threads. I went from corner to corner without lifting the pen until I made it to where I started.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
Help me understand how you used S-Note to cal

Gotta love the autocomplete for S-Note (Snot) in your note. All good.

Anyhow, I have tried opening S-Note to do full edge tracing as a means to calibration, but I just can't seem to do it.

Here's the problems I am having, maybe you have some advice on how you did it?

- Holding the tablet in portrait mode (long edge up and down), I cannot get to the far right or left edges of the screen to draw onto. I either can't get the drawing page to extend to those edges, or if I zoom in, I get a vertical scollbar on the right that doesn't allow me to draw there. EDIT - just realized that if I collapse the toolbar that lets me select pen width, color, etc, the scrollbar goes away. Okay, so now I can get to the far left or right edges.

- Still holding the tablet in portrait mode, I cannot get to the far top or bottom edges while drawing. At the top, I have OS status bar (notifications, speaker status, wifi status, battery status, time, etc), and a menu bar for S-Note. At the bottom, I have a menu bar with things like being able to toggle between drawing and panning, adding page, etc. Is it necessary, in your experience, to get to the entire physical extents of the screen for the cal to work, or is drawing along the edges in a continuous line for this less-than-fullscreen areas sufficient?

- Any idea if this is maybe something that needs to happen the first time S-Note is opened, or should it be able to be done at any time?

Thanks for reading, and your replies, I sincerely hope this end up being a forehead-smacking (on my part) outcome.

Been trying to make a good edge all around the drawing page, and one place that trips me up is that I hit the 'save' button while trying to get the pen to draw all the way to top edge of the drawing page. I am assuming that somehow I need to avoid hitting the 'save' button, but still hit that last row of pixels that are just below the save button for this to work, eh?

-Mike
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] rtiangha:
I think any drawing program might work. I used Autodesk Sketchbook since you could hide virtually everything to get to all four edges. I did make sure to draw a 1-2mm thick border and made sure there were no white spots left. Sometimes when scribbling on an edge or the corner of the screen, the line wouldn't actually touch the end of the screen until I did multiple passes (perhaps that was the calibration at work?). Who knows, maybe you don't even need a drawing program (definitely makes things easier to see though) and all you have to do is keep moving the stylus back and forth multiple times continuously on the edges. I did make sure to not lift up the stylus until I was finished, though. You wouldn't believe the hand cramps, lol.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
Thanks for the reply and sharing your experience. I have Sketchbook (the Galaxy version), so I opened it up to give it a shot.

If you don't mind, I have some additional questions, etc, to try to make sure I am doing this as much the same as you have, which apparently gave you some good results.

In my case, the drawing onscreen gets offset a bit below (south of) the stylus contact point, but more so to the right (east of) the stylus contact point.

If I flip the tablet 180deg (so the home button is now at the top, north), the offset becomes a bit above (north of) the stylus contact point, but just about perfect in the right/left (east/west) direction.

I hold the stylus right-handed.

I try to use the tablet in the flipped (home button at the north) orientation for drawing, but the north/south offset still makes it pretty lame.

On to my questions:

I can get all but the top menu bar to disappear in Sketchbook. Are you doing something to make that menu bar disappear, as well?

When you say going back-and-forth to get the edges complete, do you sometimes go beyond the edge of the screen, and onto the body of the tablet a bit?

Or are you keeping the stylus contact point still within the screen/drawing area, going back and forth, until you finally see a line where you need it?

In my experience, to get the drawn lines to hit the full left edge, for example, I have to move the style about 2mm past the physical edge of the screen, onto the body of the tablet, to get the line to draw all the way to the edge.

Thanks for your replies and help, I'm still holding out I can make this thing happy again. And if that means some hand cramps, okay.

-Mike
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] rtiangha:
Yeah, I had something similar and I'm also right handed. In Sketchbook, uncheck Toolbar Always Visible to make it disappear. Yes, I actually had to go outside the screen area. Rather than just trace the edges, what I did was a sort of very fine zig-zagging motion going back and forth between the screen and the bezel as I went down the edges (I didn't draw all the way to the edge of the device though, more like 1 cm or less past the edge of the LCD). I did make sure to completely fill in a 1 to 2 mm border around the edge of the LCD while I was at it (I used a fine point on the drawing tool though; can't remember the number but it wasn't the default as it was too thick. More like slightly greater than the lowest setting), and taking special care and doing multiple passes whenever I noticed the 'ink' not reaching the edge of the screen or white spots in the border I was drawing that wouldn't fill in on the first pass. They would fill in eventually the more times the stylus went over those areas; I just had to keep drawing over the area until it did, sometimes moving on and then coming back to the area later if nothing seemed to be happening. And again, I didn't lift the stylus up until I was completely finished drawing my solid border, which meant that if I screwed up, I would erase everything and start again from scratch. I don't know if what I did or how I did it was overkill, but the immediate result once I was done was the blue dot being directly under the stylus point, rather than 1 or 2 mm off. I was surprised that it was so instantaneous.

I'm also running rooted stock with no custom kernel, so it's possible to fix this without having to flash anything special.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
So glad that there might be hope given that you are running stock, albeit rooted.

The back of my mind wonders if you being rooted, and having an app that requires root, might inadvertently be contributing to the fix. Anyhow...

Some questions inline with your text below: (and thanks again for the replies, can't say it enough. Although now you have turned me into an obsessive screen scribbler in hopes of making this thing work again)

And I suppose that you are holding the sylus normally while you do this operation; meaning you are not changing the tilt or orientation of the stylus to try to get your full edges marked, correct?

Uh, define 'screwed up'. I notice that while I am going off the screen and onto the bezel, certainly less than 1cm away from the screen, sometimes I see the 'menu' and 'back' soft buttons illuminate on the tablet. I believe that illumination happens when the tablet sees the stylus. Assuming that's correct, it leads me to also believe that in going beyond the screen and onto the bezel, I have gone too far and the tablet interprets that as having lifted the stylus. Agree?

And, so, in your explanation, is any time that you see the soft buttons light up, you know you've screwed up and need to start over? <cringe>
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] rtiangha:
I use the stylus normally. That may include tilting the stylus at a different angle to get at some of the hard to reach places. Sometimes I'll rotate the tablet while scribbling to make things easy on myself but in general I try not to change things as much as possible once I start.

By "screw up" I mean accidentally lift the stylus. If I notice a broken line because my hand starts to go spastic, then I've screwed up.

The one time I avoid the bezel is at the bottom. I try not to hit the capacitive buttons for fear of it thinking that it's a different input and thus no longer one continuous line like you say. But I do try to fill the border to the edge as much as possible. The other edges seem to be fine. Or at least, I never encountered issues by scribbling outside the screen in those areas. Might be easier to start from the bottom and work your way up.

Rooting should have no effect on the calibration. I only mentioned it as an aside. The main point I was trying to make is that this method works fine on a stock kernel.

But honestly, the best way to test this all out is to try it for yourself. If it doesn't work and you're ready to throw in the towel, you could try flashing Civato's custom kernel which claims to fix the calibration stuff out of the box, for the most part (it's based on Samsung's kernel source with some of his own tweaks) and see if that works for you. You can find it by searching one of the Note 8 Android Dev forums (I don't have the link on me).
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
Absolutely re:trying it out myself. I have been all along, but have not been able to effect any difference yet. Hence, my clarifying questions to understand your particular experience better.

I suspect part of the problem is when I see the capacitive buttons flash; not because I am hitting them, but because I think I am going too far onto the bezel with the stylus and creating what is essentially a lifted stylus event. On some areas of my tablet, if I go less than a millimeter onto the bezel, I get the capacitive button flash. Quite hard to find that perfect balance between drawing onto the bezel to get the line to appear on the last set of pixels at the edge of the screen, versus going too far and triggering a lifted stylus response. Each edge of the screen behaves a little differently, which makes sense given the offset, but the corners get incredibly touchy where sometimes I am still on the screen, not the bezel, and a lifted stylus is triggered. Grrr, sigh.

Getting all the way around the tablet without causing a capacitive button flash, which presumably indicates a noncontinuous path, hasn't been successful yet. But still trying and hoping...

Thanks again,

Mike
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] mruddick:
Yeah, for some reason I keep holding on to wanting to keep it all stock. Probably because any time I have entertained rooting and going custom ROM/kernel, I find conflicting information on how to do it, where to get files that are official, etc. I don't have a fear of interacting with the tablet, flashing it, etc; but there seem to be so many tools and places to grab ROMs, and lots of conflicting advice or information.

Regardless, the Civato kernel or ROM you mention I think is SphereKat, right? Ie. this one http://xdaforums.com/showthread.php?t=2775998, yes? I think to do it right, both kernel and ROM need to be applied.

Edit1: Okay, I threw the towel in. Rooted, tried the kernel above, but it made some apps and games kind of wonky/choppy, and I was seeing some Chrome app crashes. Then I realized a newer civato kernel was prob better, the one that depends on kitkit bootloader (can't remember the name of the kernel). So after a few learning curve moments, I was able to get that kernel in, keeping the stock ROM/OS, and things seems REALLY good now. For sure hte SPen is working like it should. Dunno if I will investigate doing a cutom ROM to maybe get a bit more SPen accuracy, but it's mucho mejor now.

Thanks again for the detailed responses, it at least gave me confidence that I did about all I could before going root route. Now I suppose Samsung will release Lollipop, with SPen fixes, for this tablet tomorrow...since I can't get OTA updates anymore from what I can tell.

-Mike
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] rtiangha:
Yeah, just the kernel is enough. I wish I knew how civato "fixed" the S-Pen issues in the kernel and I'm curious as to why Samsung doesn't set their kernel to those settings by default.

And yeah, you won't get anymore OTA updates from Samsung anymore, but I have a feeling that outside of *maybe* a 4.4.4 update (the GT-N5100 got one in Poland back in January), that might it for this tablet. We'll see, though. Anyway, glad you got your tablet issues sorted out!
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] fedex2go:
Hm, sounds like a lot of BS, one can't get to the screen edges in S-Note (due to horizontal status & menu bars).

It's really upsetting that Samsung omitted such an important tool as calibration, it's well known fact that Wacom digitizers tend to loose calibration over time (due to magnetic nature), and need to be re-calibrated. Heck, my 2005 Toshiba M200 has one, and 2007 Lenovo X61T, too. I guess it's better to stick with Windows tablets if good pen support is needed.

My I467 is a paperweight now, S Pen is off 1-2mm on part of the screen (maybe due to 4.4.2 OTA update, not sure). Now use my old trusty X61T for drawing. If I won't be able to fix calibration issue on i467, then will buy Dell Venue 8 Pro with N-Trig digitizer and Win8.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] rtiangha:
Use an app that hides the bars. I used SketchBook in full screen mode. Works fine. Although I think it just makes it easier to see where you're drawing. You might not even need the program; maybe all you need is to move the stylus to the extremes of the screen. I really wish someone out there who knows the definitive way to calibrate these things would pipe up and talk about how the software calibrates itself.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] fedex2go:
Correct me if I'm wrong, but such apps require root. Which my Note doesn't have.

LOL, it's a lot of maybes.

IMHO, it's a digital world - either there is a specific procedure to calibrate, or there isn't.

Trying all sorts of things without specific knowledge what to do - waste of time, it's like looking for a black cat in a dark room.

I think that smart thing to do here is to learn this lesson and stay away from Samsung in the future.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] sefrcoko:
Yes Samsung messed up but it's not like we don't have a solution :). I flashed civato's rom and kernel and never looked back.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] fedex2go:
"We" who??? I have i467
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] sefrcoko:
Right, well I'm not really familiar with your model to be honest. Just saying that a fix is possible through custom firmware if available for your device.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] fedex2go:
Right, well I'm not really understand what are you doing in Galaxy Note 8.0 thread then, to be honest
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] sefrcoko:
The Note 8.0 threads (like many on xda) are actually meant for multiple devices that are still similar in nature. In the case of the Note 8.0, this includes the N5100, N5110, N5120, etc. For your information I have the N5110, so I am definitely in the right place. Remember we are all here to share and help each other. Respect is paramount. Good luck :)
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] fedex2go:
Luck is not a factor here. I467=Galaxy Note 8.0 (AT&T). It takes 10sec for a reasonably intelligent person to figure out. Instead of paying minimal attention and reading the actual posts, you hurry up and say there's a solution by flashing. It's not applicable for I467, it cannot be flashed.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] sefrcoko:
As always, I read through the thread bud. I see you have like 17 posts so far, so still relatively new to xda. Instead of being confrontational, understand that my post was directed at the other Note 8..0 models like the N5100, N5110, etc. If it doesn't apply to your variant then so be it. This thread does not revolve around your variant alone. The same applies to many other xda threads. Good day sir.

This is the secret code of Samsung to get to Factory Mode, using Calculator : (+30012012732+

Then : *#0*# in Calculator

You should get to Factory Mode where you can test different functions, especially Wacom Test, If it fails the test, your Lcd is defective ( S Pen cable is from LCD ), this one is an example.

The test won't do any calibration, just Pass or Fail.

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Toyeboy:
I have the same model as you and I'm thinking I'll just return it. Bought it off eBay but calibration is a few millimeters off. I can't flash this so there's no point.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
Just calibrate it through a note.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Toyeboy:
So I just scribble on the edges in S Note? And keep it a continuous line correct? Are you supposed to go off and on the and when you do this or stay on the screen the screen time? I think that is what you said right? Also I'm left handed does the s pen function any different for me?

I with love to get it calibrated as this tablet is plenty fast, smoother than a Galaxy Note 10.1-2014 I tried.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
In S Note, draw a line along the edge of the display, and without lifting, follow along the next edge and continue until you have made a complete outline of the display.

It does not matter which side or hand you use. Some peeps find it easier to allow the pen to rest at an angle that your hand naturally draws, and maintain it even at difficult drawing lines.

Some people may find taping card board along the edges to keep alignment straight.

This is done while tablet is flat on the table so you can do a good job at drawing.

I noticed if you go into developer mode and turn on traces, you can judge how well the alignent is done after doing the alignment trick.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Toyeboy:
Okay how do you get rid of all the menus ins note
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Toyeboy:
I traced for a long time. It didn't make any sort of difference in the accuracy so I'm frustrated with it so shipping it back tomorrow. I would've flashed the kernel had I not had the att version with locked bootloader. I ordered a Galaxy Tab A 9.7 with S pen instead found it for $180 on eBay. I really like the smaller size of the Note 8 though. So it's a bummer, but Tab A has Android 6.0 so that's definitely cool.
