I've done a good bit of research and I'm surprised that nobody has asked how to fix the crappy multi touch streak has.
Here are the issues it currently has (tested in MultiTouch Visualizer 2):
-Does not read second touch until the finger has actually moved
-If you release the second finger without moving the first the phone will not recognize that the first finger is still touching the screen until you move it
-The screen will not register more than 2 touches (the app will just turn the screen blank when a third finger is placed)
So here is my question: Does anybody know of a way to modify the multi touch (response and number of points) through any means like build.prop or perhaps a modified kernel?
Same problem. Still looking for solution. It`s problematic with emulators and most games.
So there's a (what I thought was a dead spot) sensitive spot near the top of my screen. It's about an inch tall and spans the whole screen wide. If you press normal to hard it'll do a instant single click. But I found out if you touch it really lightly it'll function like normal.
Now the weird part is it stays w/ the rotation. If you turn it upside down or sideways the bar always effects the same icons and widgets in its path so I don't believe its a hardware problem.
Anyone else have this problem?
i'm assuming you're using a 101 as this seems to be a normal defect of the device. there is a fix where you have to dig inside your archos to get rid of the flex or you can just make a habit of lightly touching it. it's a pain trying to drag widgets on the screen b/c of this.
you can try to recalibrate the screen to see if it may help any.
Yea on a 101 and the recalibrate doesn't help. What is this fix your talking about?

(You will have to copy and paste the link. I don't have enough posts to enter a URL. )
I have also read that it may go away with time and multiple recalibrations, or that it may be caused by a "rogue" application and/or widget that has issues with the device.

Try that one.
Ok I noticed this little issue with the touch screen.
Maybe this is how it is meant to work but just wondering if its the same for everyone.
Basically when you first touch the screen and then move your finger in tiny movements back and forward like 2-3 pixels distance the screen just recognises your initial place you touched. It doesnt recognise the little movements. You have to make a bigger movement with your finger and then the screen starts recognising these tiny movements.
Its like its been set up with software to only track your finger if it moves a minimum distance. If this distance is not met then keep the original place where the screen was touched.
Best way to see this is get a multitouch test app from the market. Basically just one that gives you a dot under your finger when you touch the screen.
Touch the screen and move your finger in tiny movements back and forward. Like really tiny (2-3 pixels in distance)
Does the dot move or does it stay there like its stuck ?
Then you have to make a bigger movement with your finder before the dot starts moving. But after that you can do those tiny movements you did before and the dot moves.
Hope someone understands what i'm saying.
My old phone didnt do that.
Someone try this please
What about touch screen settings are their any ??

Same result for me, very small movements of the finger are not registred...
I think the touch screen driver needs work or calibration, see other posts regarding screen sensitivity, screen doesnt pickup light touches sometimes, sometimes I have to make a defined press on the screen for it to work. I have decided I dont mind this now as it is less likely to pickup accidental presses but I still think it is a little under sensitive.
The thing is if you make a big movement and then with your finger still held on the screen make little small movements it recognises them. Its only when you first touch the screen it doesnt recognise the small movements.
Its like its been set up with software to only track your finger if it moves a minimum distance. If this distance is not met then keep the original place where the screen was touched.
Maybe for typing etc so you dont accidently hit another key.
Anyone else able to confirm ? See if it detects tiny movements when you first touch the screen, and then move your finger around for a bit and then try tiny movements it should work then

Yup, definitely not a bug IMHO - just tried while playing angry birds and it nails it to the half pixel - there's nothing wrong with the hardware. I find the lack of registration of small touches a major plus, I suppose they should add a menu to disable it for those who don't like it

I know exactly what you're talking about.
Here is a test for all of you, go onto a webpage, view it at it's native resolution, which will be bigger than your screen res.
1) Drag the screen at 180 angle directly horizontally, say to the right do this slowly and move the screen a bit.
2) Now try scrolling the screen upwards or downward, slowly and carefully without taking your finger off the screen.
3) you should find that the screen is now not responding to your careful touch to scroll in a different direction you originally was scrolling.
4) given that you seem to be locked into scrolling left or right only, drag fast and long distance either upwards or downwards (or diagonally)
5) hey presto, you can now scroll in any direction again with movements as small as you like
Its weird on angry birds, it detects these really small movements.
But on Nova HD for dragging the camera it doesnt detect these really small movements.
However if you make a big movement it then will detect the really small movements as long as you don't take your finger off the screen or you have to start over again.
Another way to see this, is on the lock screen.
Touch the lock image wait a few seconds then move your finger like 2 pixels left and right (really small amount).
The lock image won't move at all. However if you then make a big movement so the lock image starts moving (and keeping your finger still on the screen) then move your finger 2 pixels left and right it moves.
Touch the image and wait a few seconds , then move your finger
Seems like its something to do with software. Not sure how angry birds manages to avoid it.
I reckon it can be patched so it doesnt act like this. I wouldnt have a clue how to do it tho. Someone might tho
Anyone tried it on the lock screen? Same thing ?

This?
Yep thats it there ^^^ . Thanks.
Hopefully it can be modded. Looks like samsung added a minimum threshold
Yeah I hope so too... looks very annoying.

Hi all.
As in topic, I have issue withy me screen. What I mean - when i use 2 fingers (dual touch) after few sec by moving both finger on the screen they are freezing. No one point is moving. I tried this in Multitouch visualiser and as i said. Dualtouch is working only moment and it is freezing. Next problem is when i write sth. Sometimes letter are doubled or typed "s" or "d" even when i didnt type that. I'm using Jusada ICS and LagFreeV3.
Hi,
My phone seems to register double touch input while i am only using one finger
It only happens only when i pass the my finger over the middle of the screen, ie. a horizontal line in the middle of the screen. This is affecting scrolling and tapping on anything in the middle of the screen.
I just want to know if this a software (calibration) issue or a problem with the screen itself.
see attached a screenshot of multi-touch test using 'Display Tester'.
thanks.
Did you test this with other touch-tester software also?

I did, they all show the same problem.
It seems any touch in the 'Y' range between 145 and 190 will register as two touches. I have attached another screenshot. I tried a calibration tool for Nook tablet, but nothing improved.
