If you want to go hands-free, RC Willey can help with this PopSockets mount.
This mount allows you to attach your phone anywhere there's a vertical surface (like your car dashboard, wall, bedpost, or bedroom mirror). Your PopSocket will snap easily into and out of your PopSocket Mount to enable hands-free viewing. The PopSockets Mount attaches to surfaces with a single-use 3M VHB adhesive; it can be removed without leaving any residue with fishing line or dental floss. One extra 3M adhesive is included.
