On my phone hitting the arrow that sweeps to the right (next to the thumbs up/down icons) gives options one of which being a notepad type app I have on my phone, choosing that app will open the app with text containing the address. The other links look like they should allow you to copy it directly but I'm not a big smartphone guy so that's above my grade.
See if your phone has something similar.
I didn't even know what the arrow next to the thumbs up did. I tap that arrow, and at the top right is a copy link button. Thanks for making my life a little easier.
