native scrolling refer to on mobile platforms and tablets ? Does it refer to the inertia feel of a scrolling list ? The ability to pull down the list for refresh ? Or both. I'm having a hard time finding a true answer. And where can I find a list of devices/OS that support these feature ?
"Native scrolling" is controlled by the core scrolling engine of the native operating system.
"Native-style scrolling" closely mimics the feel of native scrolling including speed, momentum, bounce-back, response, control, appearance, etc.
"Native scrolling" tends to be used as shorthand for both, hence your confusion.
Update: To answer your last question: every device or operating system that scrolls content has its own native scrolling. In computing systems, "native" refers to the basic, built-in functionality.
"Native scrolling" simply means using the scrolling mechanisms (APIs) that are built into the OS.
