I bought this and so far it's been really good.

I have the Roam Co-Pilot universal bike mount and it works pretty good. The strap system they use has holes that do leave room to hit the finger print sensor to unlock the phone if necessary. The one I have is prior to the latest generation that looks like it has some updates. (mine has black elastic.) https://www.amazon.com/Roam-Co-Pilot-Universal-Motorcycle-Handlebars/dp/B013MDDEAO/ref=lp_6682000011_1_1?srs=6682000011&ie=UTF8&qid=1470921833&sr=8-1
