Screen Jump on Lumia 830

[Vorkosigan]

That's true it's much better with update 2 and also today I've got interesting tip on other thread (where I posted video of micro stutter) that I should try to swipe with thumb sideways instead of tip of my thumb which apparently create too much friction, which is than translated to OS as this weird jumping. To my biggest surprise it actually work O.O I don't know if problem was at our fingers whole time or it's a combination of less friction and update 2 but now it's significantly better thank you very much for your help

I was wondering myself if it was something I was doing. Especially as i also have some issues with side scrolling in apps. I'll have to try using less tip.

I am convinced I am executing some gesture to cause the glitch:
...slide up...pause...slide sideways=jump scroll 1/2 screen
I haven't found a list of secret gestures, but it's a consistent issue.

I've found interesting thing, not sure if it proves anything but at least it could be a potential reason for this scroll jitter. I've looked at how WP work with touch and find out that they actually differentiate scrolling by dragging finger across the screen which they call simply DRAG, and just flicking the screen to scroll which they specify as FLICK. That's a fact so there is actual difference between dragging and flicking which some of us see. Now remember that this micro stutter looks like a content of the screen that is being scrolled sort of jumps number of times. Well Microsoft specify that when people start moving finger across the screen manipulation event called ManipulationStart occurs and than during drag ManipulationDelta event occurs number of times until movement stops, to notify system where exactly users finger is. Did you see this certain similarity there? System deals with touch by firing delta event multiple times like screen jumps multiple times, but when we just flick the screen and lift our finger from screen no delta event occurs as same as there is no jumping of content that has been scrolled. I know it could be nothing and I really don't understand how WP work and how rich works but it sounds pretty concurrent to me. Also if that's how it is, it would mean that this phenomenon is actually how system itself works and thus all windows phone devices as well. And that would mean that some of us are seeing things or others doesn't see this thing that is clearly there . Otherwise power of placebo effect . What do you thing could this be proof that this scrolling jitter affects all Lumia phones and possible source of this "issue"?
