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.

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.

Its annoying when playing nova hd trying to move the crosshair
I'm wondering if anyone else has had this issue. There seems to be a delay or intermittent failure to detect a swipe to scroll.
For example, let's say I want to scroll down and there is a button that I happen to start my swipe on. Sometimes the button will actually get pressed instead of the swipe getting registered. It's really annoying...
Same
I have the same issue on my cowon z2 there is a lag when swiping
I think its B&N's sloppy touch screen driver, I belive there was a group working on fixing not only the lag but also adding 5 finger touch as opposed to only two. I don't think they're working on it right now because pretty Mich everyone is working on finishing the new 3.0 kernel. But I bet work on the touchscreen driver will start up again after the kernels release.

Yep, it turns out that touches do not register until you have swiped more than 4 pixels. That explains a lot. It also probably explains why my touch pen doesn't register very well. Hopefully they can come up with a fix. It is also good to know that I'm nor crazy. B-)
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.
Hello all,
I'd like to know if the multitouch issue I'm hitting is more likely to be a hardware or software issue.
Singletouch working normally and accurate.
Multitouch recognises fingers approx 1cm over actual position.
Trying to describe...
if I'm only using 1 finger its ok and the pointer is where my finger is but if I'm adding a second finger the pointer moves ~1cm up.
So both fingers are way below the position the streak thinks they are.
Using DSC v2.2 and dont hit this issue on a 2nd streak.
Tried to use the touchscreen calibration but didnt change anything.
Is it possible that this issue is related to the hardware?
Thanks,
You can test with "multitouch tester" from playstore

Ok, way easier to visualise...
Seems like I've a moveable dead zone within my streak.
To explain see attached pic.
If finger one is where it is located on the pic and finger 2 is either above green line 1 or below green line 2 everything seems to work ok.
But if the finger 2 is set between both green lines both circles are set completely to the mid.
Also depending on the position of finger 1 the deadzone/green lines move.
Can this be somewhere within android and is somehow repairable or more likely hardware?
I dont hit that on a 2nd streak with dsc2.2 (so both on dsc 2.2)
I'm pretty sure it's hardware issue.
Hi, recently I started facing touch screen issues.
My touch sensitive buttons aren't responding and sometimes the lower part of the touch screen is unresponsive. That is fixed with a gentle squeeze and a lock and unlock. Sometimes the touch behaves as if I'm using two fingers than one (scaling when trying to fast forward video using one finger )
Sometimes the entire touch screen goes unresponsive which is fixed with a lock and unlock. The scroll becomes dead slow too sometimes. Again the fix is the same.
I'm not sure if this is a firmware issue or hardware issue. The rest of the touch works fine.
I'm using a Gionee P6
I tried to trouble shoot using the secret star codes but unfortunately the menu is in Chinese for this device.
If someone could help before I send it in for repair which will take a long time I'd appreciate it
EDIT : I Was able to use the touch screen testing from the diagnosis hardware menu and there are no dead points. Every part of the touch screen responds. Except when I actually use them in Android
