I received some SMSes that show up both in my SMS app and in Google Hangouts; however for the life of me I can't figure out how to just copy that number (in order to report it as a spammer), short of either adding it to my contacts (I don't want to) or writing it down on a piece of paper and re-entering it (which seems just plain silly).
Googling around, it seems there are quite a few SMS/MMS applications in the wild and I can't tell which one exactly mine is (it says "Version 4.1.1", but I can't find an ID), but I would expect either it or google hangouts to have that functionality somewhere ... so what am I missing?
(the obvious things - long press, short press, double click etc. on the number do nothing, and the menus only show me options for blocking the sender or adding it to my contacts)
