I have this guy from when I had a Galaxy SII. It works, and you can access all the ports on the phone, but it's ugly.
tbh the biggest problem I have with it is the same problem I have with every mount for anything: I drive a 2002 Ford Focus and there are NO flat spots on the dash to mount ANYTHING. The best you can do is get it to stick with half the adhesive from the circular mount pad, and that eventually falls off.
Stupid swoopy dash.
