Sadly my phone is plagued with the touch screen ghosting issue as well.
Scrolls sometimes register as touch, scroll up will sometimes refuse to move up, zoom in/pinch will cause erractiv movements, etc...
I've tried resetting the phone and messing around with the touch sensitivity, motion smoothness settings, etc... but none of it is working.
Very disappointed that brand new phone I've had for for about a week is causing issues already.
Samsung, please respond with something other than the typical "try resetting" response, or I will have to return it before the return window closes.
