And no other phone utilised a built in stylus (in fact, no other device as an active digitiser outside of the Note line). No other device manufacturer actually came up with ways to make said stylus useful.
Scrolling was a thing when Windows Phone still ran on capacitive-screened HTC's (or even further back on S60 Nokias). So was multi touch pinching. None of the phones at the time were as
refined as the iPhone, but many had similar or greater levels of functionality.
Perfect example is the iPad. It is six generations old yet still has zero split screen abilities. It's a glorified, enlarged iPhone.
Ironically enough, the Note was disruptive enough to force Apple to make the iPhone just as large. It may not be as wholly revolutionary as the iPhone was, but it forced every OEMs hand- and was not the result of a copyist, but of gap identification and risk taking. The same qualifiers that the iPhone succeeded under.
Apple copied the "copyist". Hopefully that doesn't fry your brain
