Hello.
I'm dealing with this PDA that's from a friend. He told me that it's very slow (it had WM5). I update with some homemade ROMs to see what happens and the result has been really annoying:
Operations are sluggish. Even the screen aligning process is horribly sluggish. Everything is slow as hell. The screen seems to miss some taps, too.
What's the problem? Somebody with this problem?
EDIT: I have seen that the touch screen is failing! The taps are hold when the stylus is not on the screen. Could it be a failing touch screen?
Well, later to have checked and tested intensively I've come to the conclusion that this lack of responsiveness is produced due to a hardware error. The touch screen is failing and the CPU processes a large a mount of taps without actually touching it, so it's too busy to process any other task properly.
I hope this help to anyone having the same problem.
Thank
Issue with touch screen ?
Concerning your sluggish PDA, is there a plastic film to protect the screen ?
Some plastic films may cause very weird behaviours as the screen could be fooled and act as if some point on it would be touched. It's all the more true when the film is in contact with both the screen and its frame, due to bad alignment when sticking it.
I had a similar issue with a Tomtom One (1st issue) and was about to send the device back to warranty... everything was solved when removing the protective film !
It's rather obvious with first generation films that were really thicker than new ones.
Hope I was of help...
if you cant fix it and are going to get rid of it i will take it off you. mines motherboard is scrambled, but the screen is fine.
thats if your getting rid of it.
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)..
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...
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.
Since I have had the OPO I have had intermittent issues with the touchscreen requiring reboot to solve. Since upgrading to CM12 the issues seem to have largely subsided but last night I dropped the handset from about 18 inches off the ground. The top left corner of the screen shows a bit of cracking on the glass and now I notice that there is an area in about 1/3 of the touchscreen that is unresponsive. The lower and upper parts of the screen work but now there are some apps and functions I cannot use with the touchscreen and I notice I have having a lot of trouble with the pattern unlock screen as well.
My question is whether the entire digitizer screen will need to be replaced or if there is a possibility that the ribbon connectors or some other connection is possibly causing this issue. I have attached here a pic of the physical damage and a screencast of multitouch test that I ran to demonstrate the area affected. It seems to start around y0=400 and continue to y0=1100 or so which is quite frustrating. In the video I am just running my finger up and down the screen and also across diagonally to demonstrate the problem areas.
Apparently I cannot post Youtube links since I am a new member but the video is on there posted under
"OPO touch screen issues after drop"
Anyone with insight would be much appreciated as I certainly would not like to have to tear this phone down and replace the screen assembly.
I doubt it's a ribbon cable, otherwise your whole screen would be dodgy. I think you need a new digitizer + LCD.
Here's a link for the video you are trying to link to.
