Funny I was trying to do the same two days ago..because first of neither do I have wifi at home..and I'm not going to pay for that extra when I already have it inherent in my data plan that I'm already paying for to begin with(even my service provider wants to make an extra buck out of me, you & them)..
I played with it almost the whole day through..
I even created a "new network" around my area from my Note5..so my Note4 and my other divices connect and share that in that way they can work together..but that network is not viewble
not in my Note4 or other devices..just in the one I created from(the Note5)..
What
@MrJavi (he is the man of the goog goodies) says sounds very interesting..but a little dangerous for someone who doesn't know what he is doing(that would be me!!!..lol..but I'm tempted because I need that sharing connection)..
