Nope. Tried it when I first about the problem and tried it just now. Up and down and diagonally. No point in side to side because I'm never going to do that......ever. The only time it stutters is when my finger accidentally moves past the screen and I accidentally bring down the notifications bar. I'm on 6.0.2 with an iPhone 5.
keep doing it and fast. you will see im right.
Who uses their device like that??
if you are scrolling very fast, say its a very long list and you wanna get to the bottom.
