Touch Sensitivity

Hey is anyone elses GTab's touch sensitivity kind of off?
I noticed, compared to the iPad and Galaxy Tab, some times it takes me 2-4x of tryinng to press something to get it going.
Its almost like the screen cant pick it up sometimes. And sometimes when scrolling, it selects things, when im just Trying to scroll..
Also the top left HOME button on screen is always iffy, most times ill need 2-4 more times 2 press it to get it going.
I am using TNT 2.2.
Anyone else noticed this? i feel like its hardware.

Definetely not as responsive as my EVO. Maybe its the cheap screen. I wish it could be fixed via software, but fat chance. I guess not all capacitive screens are created equal.

You nailed it. IMO Samsung has been making the best color screens for years.

Have had absolutely no problems with touchpad responsiveness from my gTab... Just as sensitive and responsive as my Dinc.
Really does seem like this hardware is hit or miss... Some tabs have no issues some have many.

You guys are just plain spoiled. I've gone through Palm IIIx to now the gTablet, and it just simply has the most responsive touch screen that I've ever used, but I've had recent experience with the dreadful Augen GT and the slightly less dreadful White Pandigital Novel, both of which had worse touch screens than other devices that I've used.
One thing that I do, do for the gTab though is to clean the screen quite a bit. At a minimum I do so before every use as I find the fingerprint/body oils buildup to be annoying in fairly short order and it might have some impact on touch responsiveness. It's the worst fingerprint magnet that I've ever seen actually...

No issues here with single touch sensitivity, pretty good on that. Just as good as my Nexus One. Multitouch and pinch-to-zoom still a bit flaky. I am hopeful that will be resolved by software and/or driver improvements, as it was on the Nexus One.
The only issues I have are when the screen is too dirty or too clean. When I really scrub and clean the glass off entirely, at first it's a bit too "sticky" almost when my finger contacts it - maybe that's because it's winter here in the Northeast and my skin is dry. Once I've used it a bit and it gets some finger grease on it, it works perfectly. But if it gets grit or solid dirt on it, that can definitely interfere with the touch screen too, as with any capacitive screen.
I suspect the optimal thing would be a really good screen protector that's easy to clean and has that smooth finger contact feeling out of the box, like the iPad's glass does, for example, which I think has something to do with the oleophobic coating.

Typing this on my gtablet. The issue for me is the keyboard. There are parts of the screen that are unresoonsive making some letters not get tapped. The A key and l keys in particular. As a result I can't type smoothly or naturally because I will make several errors along the way. This does not happen onky iphone or my wires ipad.
it might bemy rrleason for sending it back as it takes too ongoing totyr correctly and I get tire d of all the corrections.

Well if your using the stock tnt keyboard, it sucks. We can learn from the ipad, with the size of the screen it has huge keys that cover a lot more of the screen then our stock tnt keyboard. I use smart keyboard pro with the key heights set to maximum and it works so much better, like 100x better. Even has voice to text.

Can people check their keyboard? I find that if I type most of the keys they type fine. However, the letter a key seems to only work when pressed offcenter which prevents. From typing properly as I must deliberately slow down and make sure it is correctly typed otherwise I get many errors. Could this be a defect in my screen?
Or is this a ui problem with tnt?
This could be a deal breaker as I misspelled every word if. Has h letter A

Letter A
I have the same problem with the letter A, and sometimes P. Otherwise touch is great

Figured why this tablet is driving me nuts. There are two dead zones on this tablet. Someone please do this test so I can figure out if this is just my tablet or all g tablets.
Download mulitouch vis test. Do rapid light touches in the area where the 'a' key is and delete key are. If I do this test in the middle of the screen it registers every single tap. But in those two areas I can sometimes tap 10 times in a row and not have a single tap register.
If this all g tablets then I think it's going back.
Also is there a keyboard with arrow keys? Trying to place the cursor can be a real pain.

Agreed bout the dead spots. The stock tap n tap western keyboard seems tominimize them due to the angles but if I try another keyboard I miss the a and the return button all the time

Downloaded the app as well because I, too, am having the same screen non-responsiveness issue. Lo and behold the area where the "L" key is is a pretty dead spot. It would register about 40% of the quick taps I did in that area. Is this is a software issue? If so, I can live with it and hope our wonderful devs release a software build that resolves this otherwise, this thing may be going back because it's driving me up the wall!

I do see the occasional missed tap here and there, but no consistent dead areas that I've noticed (the A and L buttons on keyboard seem fine to me).
Multitouch sensitivity is wayyyyy mis-calibrated though - you have to use very heavy finger presses to get multitouch to register. This is some sort of driver or calibration issue that should be easily solved.
I found a binary called TSCalibration in the /system/bin directory on my VEGAn ROM G Tablet. Tried running it from terminal, but it seems to be looking for a calibration.ini file on the SDCard. I'd be willing to bet we could figure out how to fix some of the touchscreen issues with some work, because I suspect they are principally software related.

If your issues with the touchscreen are anything like this...exchange it...
My new one requires very little effort if any at all to get the screen to respond...
However, if you're talking about the once in a while miss of a touch...yes, I agree with cutterjohn....you're spoiled. Return the device asap, so I could pick it up from an outlet...please?

There is a big difference between these dead spots and the occasional miss. I have no problem with the occasional miss. I just have to adjust to how my finger touches the tablet to get more consistent hits.
There are areas of my tablet that consistently do not behave like the other areas. Does that sound normal to you? I can't have a tablet where anything in the 2 corners is extremely inconsistent. If I have the tablet oriented a certain way the soft-buttons get put into one of the bad corners and that is really frustrating.
I don't think it is how I am holding it because the problem follows the physical corners and it is not relative to my hand. So that rules that out. And I washed my hands and gave the tablet a good cleaning so dirt/grease/grime is not an issue either. It could have been too clean but why only two corners?
I have many weeks to go on my 30 days so I will keep screwing with it to see if I can come up with anything that is a workaround or explains why it is happening. It is insanely fast and it's modding future looks extremely bright with such talented people. If I get fed up enough, I'll exchange it and hopefully get one with a even touch response for the whole screen or simply return it and wait a couple more months for Honeycomb tablets.

Whoa. That video was pretty bad. While mine is not like that (thank God), I just tried hitting the app drawer key and it only registered after the 13th tap?!?! seriously wtf. While it isn't a "dead zone" per se, that's still pretty bad. There has to be a software fix to recify this issue with the right side of the screen. (my "L" and "delete" button are pretty bad as well).

THAT is a defective product...
I'll do another video to compare with my new one...WITH funky assed salty sweat all over the screen. Works flawlessly...

Is your model that is working well running stock firmware and keyboard?
mine is tent lite and the stock keyboard is ok. It if I try to use the alternative keyboards then I get consistent misses on key presses especially on the letter a.

I'm always tapping *constantly*, like 10-20 times on certain spots around the corners and edges of the screen, I'm about to return mine because of this.. Believe I'm still in the 2 weeks with office depot, will have to go snag the $350 one over at sears and hopefully it will come with a screen protector this time (this one I have didn't come with one, wonder if that has to do with the dead spots)..

[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!
~John

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...

[Q] screen wont draw straight diagonal lines-any way to fix this?

my screen on my tab 2 7 works almost perfect, except when I draw diagonaly, it wiggles tons. the screen is clean amd it has done this sonce i first opened it. It does this regardless of if I use a stylus or my fingers, and it does the same on my sisters tab of the same kind. Is it fixable? or is ia just a hardware problem? Im an artist so this is getting really annoying, since it wont draw curves or circles because of this D:

Mine's done it since day 1 also, and as far as I know, it's a common "issue" with the digitizer. Basically, the digitizer cheap. Only way I've found around it is to apply more surface area with your finger.

S Pen Calibration?

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!
Post results!

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:

Weird titled/warped screen effect (or illusion)

Hello. So, I have purchased this TCL 10L phone 3 days ago. It is a great device. Though, I am facing some small issues. I am looking at the screen and I feel like it is tilted at some points. Like it is elevated to the left side, though it is pushed down at the bottom left corner and also center. I am talking about a fraction of a millimeter.
I think I am imagining this because I have OCD (Obsessive-compulsive disorder). Though, I am not sure. I have tried changing the wallpaper and this tilted/elevated effect was reduced. I even felt the tilt effect change. Is it possible for a saturated screen to cause that illusion/effect that you would think some areas are more elevated than others?
Thanks for your time.
