Who said Copy to Clipboard was missing in the Note 4? I am on NK4 and look what popped up when I used Smart Select:
EDIT:
Today I realised just how far the Note 4 sets itself apart from every other smartphone out with a feature that I am loving, Smart Select, I can select parts of images/posters etc...And the phone will segment the selection by what's available e.g. I wanted the phone number on a poster that was on FB, instead of having to memorise or take a screenshot I pulled out the SPen, did Smart Select, it broke the poster down into little segments, one of them being Contacts and gave me the option to simply save the number as a contact, call it etc... Just brilliant

its these little things that go a long way in productivity.
This is why I no longer bother when people want to compare a Note 4 to a 6 Plus, Xperia Z3, Nexus 6 etc... Not only does this thing have great hardware, but some of the software features are sooo much deeper and so damn well thought out, competitors are still very far behind.
