how many simultaneous touches does it support? and how is multitouch performance? (no issue whatsoever to report?)
It can track 2 points. Performance is good, but not perfect. I have an issue where 2 points that cross the same x or y axis lose responsiveness. The result is that I need to pinch diagonally rather than vertically, it's not a big problem. Other users haven't experienced this problem, but it's been the same for me across multiple roms and after numerous calibrations. Be aware of the viewing angles, the screen looks great dead on, but quickly diminishes at off angles. This is much more of an issue in portrait than landscape mode. There are Youtube videos illustrating the viewing angles. I myself don't find it too annoying.
sounds that it has similar issues as the htc desire or nexus one.. i already own htc desire and multitouch is a mess and i cannot play multitouch games or use multitouch apps... if there's same issue on gtab it's a no go for me
Multitouch games and apps work well. Most games that require 2 joysticks have the option to offset them, but even those that are on the same axis work well for me. PewPew for example works flawelssly.
does everyone has this problem? is this problem present in all models of gtab?
i don't have that problem, 2 point works perfect for me.
can you try multitouch tester to verify that it does not have any issue when the 2 touches are on the same axis plz?

tonight I can and report back
everything works perfect for me with two simoltaneus touches no y axis or x axis problem
is there the problem that occurs in vega? i.e. when there are more than 2 touches, the touch panel detects no touch at all?

Ok, some people were confused as to what my problem was with my other post, They thought it was a performance lag issue; possibly due to low memory. So I am reposting, I am also making it a poll, as some mentioned that a downgrade fixed this behavior on there units.
I have noticed my touch screen does not have smooth response in apps. To confirm I downloaded a app that tests mulitouch; I used "multitouch vis test".
When moving my finger quickly, or swiping, the finger tracking of the touchscreen seems fine. The problem arises when moving slowly or making small movements of less than 10 pixels; that is when you can see that the touchscreen does not track smoothly. You can see the output on the screen stay in one position as you slowly move your finger, then suddenly jump several pixels. It repeats this process as you continue to move slowly, often times the output on the screen is still lagging behind your finger. (it is not centered under your finger even after the jump) This happens even on a fresh boot, and I have tried the touchscreen calibration several times.
Overall it seems like the touch detection is low resolution, and can not detect fine/small movements. If the ones claiming it is dependent on firmware version are correct, then this could be fixed by Archos. If I get enough responses to the poll, I will contact Archos if the results point in that direction. If this is a fairly rare issue, then I know my A70 is defective.
Edit: From the responses here, it seems that the display can detect point touch to a very fine degree. The problem is that the movement detection algorithm is low resolution; the device has to detect movement of several pixels before outputting that movement. That means it can be fixed within software. (unless it is built into the touch screen controller chip)
I run calbrate touch screen and it`s now Ok.
Did you try this?

Those claiming not to have this issue are ahead, but the sample size is too low.

Polls can not be edited, but this is for A70 only. You having issues with the 101?
Hi all,
I don't know if this is of any relevance to the problems you guys are experiencing, but I thought the screen of my 101 was broken.
The problem was, me coming from a different china tablet with resistive screen, that I was applying far too much pressure to the screen and capacitive screens don't respond well to that.
These screens need almost feather light touch and are very, very responsive and the tracking (at least on my 101) is excellent.
I hope this helps...
I'm not sure you can accurately conclude that the touch response is low resolution for slow finger motion with the test scenario you are using. I say this not based on some intimate knowledge of Android touchscreen drivers, but on years of experience programming human interfaces at a low level for embedded systems. From using my Archos 101 and a Zenithink ZT-180 (Android 2.1 tablet), the touch response feels similar to how some mice (mouses?) interfaces might be programmed, but tweaked to compensate for the vagaries of using a fat index finger that lays over many pixels at once pretending to be a pressure sensitive mouse cursor. I can imagine the touch interface having to pay attention to how many pixels are being touched by your finger and how many of those pixels at the edges are noisily changing from inactive to active touch-wise. It's actually very impressive how intuitive it feels to use a good touch interface when I know how much logic is required to say this is a touch and hold verses a hard quick tap verses a small swipe verses whatever. As in mouse programming, there are logic thresholds based on how fast the cursor is moving and how quickly it's accelerating. It could very well be that your A70 may not have all the speed and acceleration thresholds set optimally, or to your tastes. I am only suggesting you keep an open mind and dig deeper to learn how these things work.
Bye.

I'm not saying the hardware is low quality, and it could be software setup. I know a good deal about how these things work, or at least have the ability to understand the technical side. I am an avionics Tech by trade.
When testing the slow pixel to pixel fine movement adjustment, I do not slide my finger, I roll my finger on the screen. This allows smoother and more precise small movements. It is a technique I have used on other devices that works very well.
The issue, is that my phone and 10in tablet (non Archos) does not behave this way. It is a usability issue. When playing a game like Angry Birds, how precise you can aim is the difference between beating the level and failure.

I have noticed this issue too, with "multitouch vis test" When i move my fingers over the screen slowly it jumps at least 4 Pixels.
But the screen has not a low resolution, when i lift my finger up and place it down again, i can "select" for example 412 then 411.
I have the archos 70 it

Edit:
When i use this program on my Desire HD, ich can slide from Pixel to Pixel by rolling my finger.

Definitely the software movement detection algorithms then.
If we get some more votes on here, I am going to point Archos in this direction.
hardware or software problem...???
I have already contacted Archos support about this. They just told me they've never heard of this problem... I responded back with more detailed info and they have just ignored me.
I have also posted info on this on archosfans.com forum. There doesn't appear to be many people who care, or have this problem. I am trying to find out if there is defective hardware which means I need to get it replaced BEFORE I void the warranty with the developer firmware, or if it is expected because of software optimization that will be fixed.

Can a few people please try using Multitouch Visual Test and post results? I am wondering if any A70IT, or any other Gen 8 touch screen actually works properly. I am wondering if anyone has a an A70IT that actually picks up every pixel like it should...
If you don't have access to get it from the market (it is not in AppsLib), I am posting a link to the apk to download. It is just a development tool, so I am sure it is ok.

that poll is completely unscientific
don't care about the poll
I don't really care about the poll. I have this issue and trying to figure out if anyone else has it or if I have a defective device that should be replaced. This was the only thread I could that related to my problem, and the original post explained it perfectly.
Should I start a new thread about this problem rather than a reply to this poll?
Coordinates seems to increment/decrement approx +- 5 only. Slow movements are delayed somehow. Not really a big problem, but if it is a software issue I would really like to see some improvements in the future.
It isn't scientific, but if a lot of people had participated, it would have been a good guide.
It is rather annoying, but no point in replacing it if it is a common issue with every tablet.
Marine6680,
Exactly my point. I don't want to waste my time in trying to replace something that might not be broken (in a matter of speaking).
I just got my Archos 28 a day ago.. and while I was playing with it the screen randomly starts to get jumpy while using my finger. When I use a stylus it works perfectly, but I'd rather not carry around a NDS stylus everywhere I go. I've calibrated many times using both my fingers and the stylus, but it's still nearly impossible to type on the keyboard or drag icons around the main screens.
Are there any alternate calibration programs? Could this be a hardware issue?
Have you used the one under setting>reformating>touch calibration..... try that one and reboot..
sent from epic 4g
About 15 times... Haha.
It's weird because it's like it detects the full surface of my fingertip so it thinks I'm dragging it or something.
The 28 uses a resistive screen, which will not respond as well to a finger tip as the higher end conductive screens. The resistive type screens also require a bit more pressure than capacitive screens. Having used resistive screens for years prior to todays capacitive ones, I've always found using your fingernail instead of finger tip seems to works best if you are not going to use a stylus.
My finger works nicely on my sister's Archos 28, and we got them at the same time. It's actually a really nice resistive screen, some people thought it was capacitive until they used a nail or tried multi-touch. I don't think it being resistive is the problem though, seeing as I can use my sister's perfectly fine...
I want to try calibrating it using a different calibration app than what is already included in the Archos. I saw a thread somewhere on the internet about another application that worked for someone, but that was before my problem happened. Now I can't find it.. Haha.
Hy there.
I just got my hannspree SN10T1 tablet.
I bought it because it have a 10 inch capacitive screen and the tegra 2 processing power.
The thing is the specs says it has a G-Sensor, so i installed a game that i have on my htc desire.
The game is called Shaky Towers ( http://android-apps.com/articles/reviews/a-review-of-shaky-towers-for-android ) .
The point of the game is to tilt ur phone (the tablet in this case) sideways in order to keep the blocks from falling, but i had A HUGE BAD SUPRISE to se that my tablet did not register any sideways movement.
What is going on ?!
I saw that the auto rotate works in the browse and in other apps, so the sensor seems to be working.
But what with the games ?
I have to say that this is not the first game i tryied that does not record sideways movement.
So what is going on !?
it seems that the sensor is fine.
the problem is with the game.
it doesnt record any tilting of the tablet.
other games work perfect.
Looking at the screen under bright light at an angle, I was able to see the matrix of sensors under the glass: 30 rows and 40 columns for a total of 1200 sensors.
Thus, the number and spacing of sensors is similar to other good quality tablets (Asus, Motorola, Samsung) and much better than cheaper brands (i.e. Le Pan).
I'm not sure how relevant this information is but I didn't find it on any forums or on the Web.
Anybody has this info?
Thank you.
Interesting. I wonder how this can affect how many touches it can sense.
Sent from my MB860 using XDA
ten. it can sense ten fingers on the screen at the same time.
download the multitouch tester from the play store and try it out your self.
honestly the only way it can be usefull, is for piano apps
I am more interested in the accuracy of the touch screen which I believe is related to how dense the sensors are. This density will have a greater impact when smaller areas are to be touched (like hyperlinks in browser, small keys on keyboard etc) - or am I wrong?

Right. More sensors = better accuracy.
Hi,
Teclast T30 has a good hardware, but some reviewers say it has a bad touch sensitivity and a high touchscreen lag.
Are there any owners who can confirm the problem? Did the updates improve it?
Thank you!
It does have couple screen issues:
-slow screen refresh rate
-poor touch sensitivity
Flashing firmware somehow improves the performance.

Please install Touch Multitest and Screeninfo apps and share the values you are getting.
1. Touch Multitest - my average touch samples per second is 40. In my huawei phone im getting 180.
2. ScreenInfo - refresh rate is around 53.65 fps. Almost all phones are 60fps.
3. You can also use any drawing app like ibis and see if ink is lagging as you draw.

I have exactly the same values as you.
40 samples per second and 53.64 fps BUT I can't feel any real issue in real world use.
I haven't installed any drawing app or any other demanding app, but scrolling down or app using a web browser and typing here for XDA forum using Tapatalk is flawless and accurate.
The tablet is really fast and after using it for just a few hours, I can't feel or see a real issue.

Good to know there are no issues with your unit as I also got a T1P3 fw v1.04_20191108. probably just a software issue that can be fixed by a firmware flash.
Actually for basic use, no issues with touchscreen especially if you are swiping gently. But if you are used to swiping fast like flicking, there will be instances the screen does not respond well due to low sensitivity. and if you will use it for games like Call of Duty, it will not be a good gaming experience.

No bothering. I like your videos.
The behaviour is similar to me, maybe a tad better.
The distance between the finger and the icon depends mainly on the speed of the moving finger.
BUT, I'm pretty sure my previous phablet Chuwi Hi9 pro should have the same "issue" probably due to the huge surfaces of those tablets.
T30 is 10.1"
If you try the same thing on a Samsung or Huawei tablet of 10" what will happen ?
Also, smaller screen phones doesn't have that issue ?
I only have this device and I can't test anything else.

If I try this test on my phone, the gap between finger and icon/paint is not that far. I think teclast used a cheap touchscreen hardware to cut on costs. Could be fixable by a firmware update but I doubt they work on firmware updates.
Hello, I am about to buy this tablet. I see there is a problem with the touch sensitivity. I have checked videos and reviews and YES, it does have a lag. Has this been solved in any way? For example flashing a new version of the stock rom.
It has been said that the Chinese 1.05 solves this but it wipes the serial number, but luckily IMEI and NRAM are not affected.
On the whole. Do you recommend this tablet for USD 170/. (without keyboard) ?
Thanks in advance.
Will this hybrid firmware adjust the refresh rate as well or just the touch issue?
