I've used this app on and off with two other smart phones. It worked great. Did some reading here to see if it worked with the S7 and Marshmallow. Seems it does. There were closed threads concerning FoxFi talk. Something about stealing/not paying for data. IIRC, using Foxfi/wifi from my Verizon phone used the data on my Verizon plan. So how is this not paying? I just want to be able to access a device while taking road trips that needs wifi. In this case it's an Echo Dot.
