As you can see, Atrix have problem on touch.
(Sorry for video is not clear.)
It recognize rapid touch as drag and it make users to experience mistouch.
(Especially when you use keyboard with touch)
What I want to tell is, HP touchpad had same issue and solved problem.
You can find the source of it in here.
https://github.com/CyanogenMod/android_device_hp_tenderloin/commit/2a2aa87ce6a45d383c413c656eb103fc1e0bddf7
But since HP touchpad's driver is completely different, it can't be directly used to Atrix.
I think Atrix's touch driver is this one.

Is there anyone can use this info and make some change on it?
This issue gets most annoying when playing Shadowgun, it moves or rotates when I actually don't won't it to, just because I quickly tapped L-R or R-L
I'd donate to the one who fixes this.

Hi.
I have a problem with my hd2's screen.
Often i press the wrong buttons when typing and so on, And ive come to the conclusion that its something wrong with the screen.
To test this ive gone to the file explorer and then grab the slider to scroll down and hold my finger perfectly still.
And even tho im 100% still it stills jumps up and down like crazy.
I can imagne that its this that makes me type the letter beside the one im trying to hit.
Anyone else has this problem or did i get a faulty phone?
Regards, Joakim
A few other people have reported "jittery" screens. Have you applied any of the decreased sensitivity hacks? I believe there's 1 on BsB tweaks, which is nice and easy.

Have you tried re-aligning the screen and secondly reduce the sensitivity of the screen using BsB tweaks? this might solve your problems
the screen is very erratic: often when pressing backspace seemingly in the right spot the screen will jitter and incorrectly register different parts of the screen. often during texts the cursor will jump to the beginning of the text for no good reason. i find that this problem is augmented in cold conditions or when my fingers are not 100% dry.
I am no authority on screen technology so can only theorize but i suspect the problem to be linked to the fact that Windows Mobile does not natively support capacitive touchscreens (the driver for our HD2s was developed by HTC ). Other mobile OS such as iPhone OS and Android do not suffer any problems like this. we can also rule out a hardware fault here as i own/ed three different HD2s, all of which suffer from this jittering. The next update to Windows Mobile purportedly includes NATIVE capacitive support, which would - i suspect - have undergone more rigorous sensitivity and usability testing and will therefore lead to a better experience on the whole. i suspect that we won't get a truly excellent experience with Windows Mobile until 7 is released. The Windows Mobile we use now is very ancient under the technobotox, which probably explains the frequent freezes, glitches and slowdowns our HD2s suffer on a daily basis despite the awesome specifications (and perhaps why - up to now, Microsoft have put so little effort into the intentionally generic and rather stale Marketplace).
I applyed the screen sensitivity cab and now it seems much better. ill report back tomorrow when ive used it a bit
help!!!!
i installed bsb tweaks 1.6 and aligned the screen,my hd2 still jitter
Hi guys, just bought a Galaxy Note - love the device except has anyone else noticed the touchscreen sensitivity is pretty bad?
I come from mostly HTC devices - the most recent being the Sensation and I could type much faster because the sensitivity of the screen seemed to register touches better.
I have downloaded SGS Touch which when the settings are adjusted are much better but, the settings always revert and I prefer a better or more permanent solution. Is it just my unit? Haven't flashed any custom rom yet so I can still return for warranty.
Would love to know everyone's thoughts and if it is a widespread problem, what did you guys do to fix it?
Are you referring to something like this?

Please update if that fixed your problem.
Hi,
Thanks for the response. It is not related to the movement issue but more toward typing... if I type the same as I used to with HTC sensation, I find that I will miss characters out. I have to be more deliberate in the touching of the screen and that makes my typing about 30-40% slower than before.
It can be resolved with the sensitivity program but I find that it keeps reverting. I was wondeing if there was a more permanent solution..
Thanks
Same Problem Here
I'm having the same touch screen sensitivity issue. The touch screen on my new SGNote is much less sensitive than that of my Motorola Atrix 4G. I'm finding that I have to press MUCH harder in order to register making typing slower and typo's common and causing usability problems with some apps. Any help in a permanent fix would be greatly appreciated. I'll continue to research this issue and post any of my own findings.
Hey guys I always knew that multitouch on HD2 isn't pefect at all, but now I noticed a peculiar behavior which I was not aware (tnx to ICS)...
enabling a function in developer settings to show pointers position I discovered that multitouch is working in a wrong way.
When you put the second finger over the screen it is recognized correctly but when you move it close to the same axis of the first one (both vertical and horizontal axis), it automatically get aligned on the same abscissa or ordinate (depends which axis was closer) even if the fingers are not aligned.
This is frustrating when I use some apps that take advantage of multitouch, such as games or emulators, because while I'm pressing a key on the screen and I need to press another one on the opposite side, but not perfectly aligned, I get a wrong recognition and often I press another key or a blank space.
I hope I was clear, but to understand better the problem you should activate that function in developer settings and try yourself.
Please give me a hope to think it is a solvable problem... maybe with a better driver :fingers-crossed:
That's just the screen I'm afraid. I've had the same issue with every ROM I've tried, and there's nothing you can do to solve it. At the very least, it's nice for me to hear some confirmation that I'm not the only one who experiences this.

I read around the forum that HD2 has hardware capabilities, so I think we need to get better input driver
The hardware doesn't support more than 2 points, and it does this rather poorly too. It's not so bad when using things like pinch to zoom or using two fingers to turn the map in Google Maps but when gaming it can be a bit of a pain. There's no driver that can increase the number of points the HW can support (if there was one then surely it would already have been implemented in Android) so afaik there's genuinely nothing that can be done about this. If there is, I'm sure someone will correct me soon.
It's a known issue and we can do nothing about it because of not so good touchscreen. Hardware problem, you know. It's present in every OS and in every ROM. For gaming I'd recommend getting a PS3 controller or using OTG cable and some other gamepads, like the X360 one.

Maybe you're right, an external controller is the best choice, but I don't want to bring with me other accessory when I'm outside... for the wrong recognition I think it's just driver fault because the problem is software side. When I use one finger is really precise the issue is when I try to use two fingers, because the driver is written wrong and read a fake position
Maybe this makes things a bit clearer. http://www.tactyl.com/fr/telecharger/39-drivers
Back in the days, there weren't that many "multitouch" apps out there for android.
If you look at the nexus one, it's even worse. http://www.youtube.com/watch?v=5puAvPqXpuc
From reading one of the booklets that came with the HD2 it all comes down to single-touch and a pinch-to-zoom gesture which both work most of the time.
Some people who developed emulators at that time, tried to avoid this "autoalignment" by putting the pads in opposite corners.
While still many people don't know that pressing on the edge of the screen, of the HD2, with at least one finger can cause
a swap in the y-axis once the second input is on the screen. (almost like in the nexus one video)
In very good light you can see this "edge-area", it's about ~4mm thick on each edge.
You can always download MVT and test it yourself. https://play.google.com/store/apps/details?id=com.batterypoweredgames.mtvistest&hl=en
Some time ago tatsumaki made a decent virtual gamepad for fpse which got rid of the alignment by incorporating it in the way he/she arranged the buttons and button mask.
No one is going to fix this by a new driver,
End of story.
Hi All,
I have a dual monitor setup with one touch and one non-touch. The problem that I had was in-order to make my touch screen work I had to make it the default. I did not want that as my other monitor (non-touch) was larger. I have been searching all the various forums for a solution. I found it on the Surface Geek web site. The instructions follow:
-----------------------------------------------------------------------------------------------------------
So, I know that you guys are going to think I am crazy, but I recently bought a new machine that has a touchscreen. I had already bought a touchscreen for my old machine and decided I wanted to go dual monitors with each a touchscreen. I found an interesting problem. It appears that Window 8 sees the touchscreen input differently than the monitor. Sorta makes sense, how is it supposed to know which touchscreen goes to which monitor. I looked on the web to see if I could find a solution and nothing could be found except others complaining about this as well. Well, I am happy to say that I figured out how to associate the touchscreen of each monitor to the correct one.
You have to go into your control panel. Click on Hardware and Sound. Click on Tablet PC Settings. Click on Setup under Configure your pen and touch displays. Then you have to touch the screen that is showing the text. Click OK or Next and then click the next one when the words come on this one. This allows the computer to know which screen is which screen. Otherwise it appears that it just thinks that both are one. Hope this helps.

Hi guys,
I have an Ideapad A3000-h from a relative lying in front of me, with something is "not working" as the only description I got. I noticed that apps would automatically start up or close and when I went to the options menu it randomly selected different entries without me doing anything. I got the impression that the touchscreen was getting 'signals' without anything or anyone actually touching it - I decided to call this 'autoresponsiveness'. I confirmed this hypothesis by making the touch actions visible via the developers menu (which was a pain in the *** with the tablet constantly inputting actions on its own) and sure enough, on the right centimetre of the screen I randomly get short touch impulses. They become faster, more erratic and generally occure more often if I myself touch the right margin on the screen.
I think this is an issue of the hardware and I would recommend to have the touch screen and digitizer swapped. However I don't have any experience with Lenovo stuff and I just wanted to ask if you guys have any ideas if this could be a software (potentially malware) issue. I don't think so, as my relative has allegedly already done a hard reset and the problem still persists. I just can't be completely sure if what was done was actually a real hard reset or just something that was mistaken for it by my technologically impaired relative
If anyone needs video to understand the underlying problem - I honestly don't know if my description is any good - I will gladly provide visuals.
Thanks in advance guys
Cheers
PS: While we're at it. Does anybody know of a good instruction on how to replace souch a touch screen unit? I only found a russian video but I don't know what kind of solvents the guy used as everything is in Russian
