[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...

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.

[Q] Improved sensitivity

With the s-pen I have to put too much force onto it before the tablet detects it. What could be the problem? The Note 2 was much more sensitive.

hopefully it'll help you out.

also try changing the tip to the white plastic one should help

Opening the Freelander PX2c Tablet

Hi folks (my first post!) and I need some help. I have 2 of the above tablets and both are working fine. However I dropped one and the touch screen has a hairline crack although it is fully working.
I have purchased a new touch screen but I am not sure how to open the Tablet so I can replace it. Can anyone help me as to how I open it without causing any damage. I have successfully replaced the speakers on my Nexus 7 but that was easy as good old youtube covers this.
Any help would be much appreciated ,
Thanks in advance

S Pen Problems

I started to have problems with my S Pen.
The S Pen was working well a day before I wrote this thread.I used it to write my study notes.But today when I pulled out the S Pen,thing became weird.
It does not want to register any touch inputs.The S Pen does have touch inputs on the left and right sides and the upper side.And the air view does not work.When I tried hovering the pen to the sides that works,it ended up registering it as a touch.
Is there anyway to fix this problem?Help is appreciated.

Do you have any replacement tips?

I did some replacement tips and still no help.
I went to my local Samsung store and they say I may need a replacement S Pen.Because the warranty of my Note 10.1 is long over(And voided too by the custom roms.),I need to buy a new one and they arent cheap.
So I hope I could fix the S Pen without buying a new one.

Jerk,
hey this might give you a lead

it addresses a similar sensitivity issue with the noteII s-pen but, it may help with s-pens in general.
if you use your s-pen alot the adjustments the guy makes in the video may be what you need. :fingers-crossed:

(Q) Bamboo Stylus Feel For Galaxy Note Series

Good evening guys.
Today I received my Bamboo Stylus Feel specially for the Note Series in the mail today. 48 bucks including taxes, shipping. However I read the instructions carefully but I encountered an issue. The pen does not have that instant response compared to the S Pen. With the Bamboo stylus, I have to press much harder on the screen in order to get it to do something.
Am I doing something wrong? Am I missing something? If this really the way the Bamboo stylus behaves? I would love the community's help on this regard because I am ready to return this pen. It has disapointed me.
Thanks.

I have one that I bought for the 10.1, and it works flawlessly for me. Never had a problem on my Note 2 either. Haven't tried it with my Note 4, though I would assume it works the same, unless it isn't updated to take advantage of the newer screen?

I could be wrong but you might need to recalibrate the stylus for the Note 4. Google can help or someone might be able to add details or correct me

Thank you guys for your responses. I will do some research in case i have to recalibrate the stylus. But like I said, it's very weird.. Because i have to press really hard on the screen to get it to do the desired action. If someone else has anything to add please contribute to this thread, otherwise I will report back here if I find any info on the Internet.

The product page for the Bamboo Stylus Feel for Note Series has the Note 4 as a tested and compatible device.

Have you contacted Wacom? (Or Bamboo or whoever... I forget who the company is right now)

I have this pen and use it with no issues.

I don't have that pen specifically, but I do have a couple of frequency-compatible Tablet PC pens.
There are three things I've noted when using them on the Note 4:
-The calibration is off, way off, and I can't just recalibrate it like I can a tablet PC or even the tablet-size Galaxy Note products.
-Tilt sensitivity works on the tablet PC pens. Good luck taking advantage of that with the amount of cursor shift you'll have, though.
-The first 20-25% of the pressure sensitivity curve, as measured in Clover Paint settings, is effectively wasted on the stock S-Pen. The pressure value just skips from zero right into that range, then ramps up like you'd expect. None of my Tablet PC pens do this; they start from 0% at initial activation force like you'd think they would.
That last point is probably why you have to bear down so hard with the Bamboo Stylus to get it to work like it's supposed to. Too bad Samsung doesn't just give us a proper settings panel like Wacom does on a proper computer.

I am getting my own pen in the mail soon as well
I hope that things will work well
I wonder if changing ROM's would help with the Bamboo pen performance.
