[Q] Tab 2 7.0 w/ Stylus

I use a ZooGue stylus with my Galaxy Tab 8.9 (Stock, non-rooted) and it works GREAT for drawing.
I recently purchased a Tab 2 7.0 (P3113) for my wife (she likes the smaller form factor) but when attempting to draw using multiple drawing apps it is extremely choppy. When using my finger it seems to be better, but she really wants to use a stylus. I've looked thru the settings and can't find anything that would make a difference. I've also looked thru the forums here at xda and can't find anyone that has posted anything similar.
Has anyone else experienced the same and if so is there a way to fix this problem?
Thanks for any insight that could be given!

I think I've run into what you are talking about. I can't draw straight lines with a stylus. when I try to draw a line, the screen registers it as a zig zag. I'm not sure if this is what you mean by "choppy." I can draw lines fine with my finger.

I noticed that it's near impossible to draw in SketchUp - it takes 1/3 to 1/2 second for the lines to catch up to my finger.
I assumed it was just the compromise you make with buying a low-end tablet. I'd love to hear that it isn't!

Yes, that's part, as well as attempting to draw small circles/curves either skips or shows as a straight(ish) line. Hopefully a solution can be found soon otherwise this one is going back.

Indeed.
I noticed this issue from day one since the first thing I did was play Draw Something. No matter the app, swiping your finger in a slow and steady manner will help notice the stutters/lag.
I also attempted to use a stylus because I thought there was some sort of weird calibration issue, but to my surprise, it got even worse. The strange zig-zag phenomenon appeared, making it impossible to draw anything. Even though it's only noticeable when you drag/swipe/draw something, it's annoying as heck. Hell, I even recently found a dead pixel in the middle of the screen, adding up to the annoyance factor.
Still got like 1-2 weeks available to return it to Best Buy, and I'm not sure what to do...

[SOLVED][Q] Any suggestions for wavy lines when drawing?

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.

S-Pen Inaccurate

l have problems with my S-Pen where some spots on the screen will not register correctly with light pressure, do that it will jutter arnoud the spot. As I want to use the note for draeing this isn't something I can just ignore.
Is anyone else having this? If yes or no please also state if you have the 3G or eifi only model.

I have the exact same problem and I'm using 3G version.
I was thinking to take my note 10.1 to warranty replacement.
Edit: also when using finger to draw, straight lines are inaccurate, see picture.

With your finger rhat is supposed to happen. Normal capacitive touchscreens aren't as accurate. The S-Pen is using different tech and is not communocating with your normal touchscreen. The pen should be pixel accurate.

That. Doesn't. Help. How hard is it.
I actually went back to the store and the show model and a new model which he got fresh out of the box for me all had the same issue. The Note 10.1 is a poorly made tablet. The pen should be pixel accurate, which it isn't. I actually got an ipad mini instead as Apple offers the best normal capacitive touchscreens on the market.

Hello my friends and welcome to samsung.
Here is how "well" the disgitisers of my note 10.1 N8000, grey, italian with 16GB + 3G, work.
FINGERTOUCH DIGITISER:
S-PEN DIGITISER:
I noticed the issue of the s-pen digitiser first, and just like you, went back to the store to check if the other notes they had there had the same issue. Result: all had the same issue. All in the same screen position. Knowing that the s-pen digitiser is very sensitive to electromagnetic field, and after watching this video:
https://www.youtube.com/watch?v=PUyI74c0DhE&feature=youtube_gdata_player I came to the conclusion that the issue is due to poor screening of the s-pen digitiser. In fact I bet that what we see is the field distortion caused by the electrical current flowing along the vertical battery wires running underneath the screen in that position. That's why the issue appears identical, at identical position on all the notes, because it is an hardware issue due to how badly this tablet was engineered.
The other issue, the one of the fingertouch digitiser, I have discovered it today, after having noticed that scrolling in my tablet was not uniform if i was sliding my finger slowly on the screen, and after having asked myself why so often I was missing to hit the virtual keys on the websites, even though I could swear to have tapped precisely in that position. Well... it appears that our nice friends at samsung equipped our beloved tablet with a digitiser with a ridicoluos resolution of around 40 x 25... (!!!!!!!) This means that we can forget forever precision touch input and smooth scrolling.
I was quite happy of this tablet when i bought it. Now I feel so pissed off that I would like to throw this piece of **** out of the window.
Another thing I noticed is that the Galaxy tab 2 10.1 of my friend does not have the fingertouch digitiser issue. Looks like in order to earn even more money than usual, samsung have introduced this feature into us starting from the latest, very acclaimed note 10.1....
wow....
kind regards, Luca.

now try that but slower and you'll see the squiggles

that's true!!!!! it's like if there's a magnetic interference along a diagonalline in the center of the screen, going from top-left to bottom-right
but only if you draw slowly on that points

Well, yes but not exactly. The inteference is vertical, and as I said, I bet my bullocks it's caused by the battery wires.
The resulting effect is just like when you put a paper sheet over a coin, and you scratch over it with a pen (never done it when you were a child?). As you know, you get the image of the coin underneath.
The "scratches" here are the oblique lines that we draw slowly, and the "coin" is the field distortion caused by the electrical current in one of the wires (of which there are four, but for one reason or another, one must cause more interference than the others).
This being a magnetic induction interference, it affects only the s-pen digitiser.
The issue of the capacitive, fingertouch digitiser (or whatever its name is, sorry but I am not native english), I guess is simply due to the fact that it has a very small resolution, due to samsung deliberately wanting to piss us off

So you're saying a fix would be to take apart the note and apply a better shielding to the battery and wires

Why would I do that if I want a straight line? Pen on paper it's the same, if you go slow enough you will not go straight...
I'm not arguing with anyone, you may be right regarding the interference, but I don't think this device was made to replace a dedicated pro digitizer.
And I did get the general impression that on other tablets the touch is a little more accurate than this one, just to be clear, I'm not saying that is the perfect tablet because I've got one lol. A used 3 tf700 for a week and the screen resolution and touch responsivnes are great, but otherwise is a P.O.S.
I think this note is a decent enough gadget for the price.

It also might not be the display itself. I got my S-Pen wet and when it dried it started to behave erratically. Sometimes it would work perfectly and other times it would be off from the position I had it placed on the screen. It was random. Replacing the pen fixed it.

Don't have this issue with pen or finger using Lecture Notes on Korean made GT-8013 bought from Amazon.

S pen cause lag/ stutters

Hey guys, got some videos showing the difference between scrolling through homescreens with a stylus and the s pen - and the s pen seems to make my launcher lag!
There are two videos a before and after of me ajusting the sensitivity of the S pen but this does not seem to help!
before: https://www.youtube.com/watch?v=fDbGR_5dQP4
after: https://www.youtube.com/watch?v=VGZ-AupQ43E
Does everyone get this or is my s pen faulty?
(it is more noticeable in real life than in the video.)

With the test for the spen when you dial *#0*#
If you move it very fast does what your drawing have to catch up to the spen if that makes sense? (Mine does but i assume this is normal, as its much faster than i would ever use it)
And have you tried doing a data wipe and flashing a completely stock image from sammobile?

I have only just received the phone and as such I am completely stock. I dont really want to wipe data for obvious reasons having spent ages setting up the phone. When i did the test the s pen does no have to catch up at all. Do you think thats the problem? Too sensitive? To confirm you have no difference in performance when using the s pen to scroll?

I only asked as i saw you werent running touchwiz launcher, so i thought you might be on another rom. But no i do not notice any slow downs while using the s pen, but i do use it very slowly, i dont swipe as fast with it as i do with my finger. So it could be that i just dont notice it.
Edit: The s pen tips that came in the box, are you using the hard ones or the softer white ones? I am using the softer one. Doubt this would make ant difference though.
Sent from my SM-N9005 using Tapatalk

Hi, I don't seem to have any "softer white ones" - although I replaced the current black one to no effect. Do you think I should turn up the sensitivity or turn it down to reduce the stutter of the s pen?

Try both. A too-sensitive setting makes the phone detect the pen even though you're not close to the screen, and too low makes it not register at all.
By default the Spen, as any Wacom pen, has a delay between drawing and the result showing up on the screen. This is because the pen is magnetic, whereas a stylus simulates a fingertip. This happens on the 2100 quid CINTIQ, too.
Are you using a case with a magnet? Have you tried a different launcher?
I'm not experiencing lag in the launcher on Apex.

very slight play in home button - normal?

Just noticed my 2 week old note had very slight rotational play on the home button. It can move a couple of degrees making the left or right side higher than the other.
Is this normal?

Mine has it also. Compared to the N1 and the N2 I owned, the home button seems less sturdy. Also it reacts differently if I push it exactly in the middle or a bit offset.
Goes with the beast I guess

Mine wobbles a tiny bit too but I got mine on release day.

Happens across pretty much all of the S series too, no?

may be normal, but fyi mine has no any movement, it fit very well to the position

Have a read through the rather large thread dedicated to exactly this issue: http://forum.xda-developers.com/showthread.php?t=2471367
In short, it's a normal issue on Galaxy devices.

Thanks. Due to workload I can't read that large thread but if it's normal then I won't concern myself about it.
