Can I use my phone as a WiFi-WiFi hotspot? I have a (non-rooted) Sony Xperia Z3 with default Lollipop installed. One challenge I often run into is that I can connect to a WiFi network, and my friends with iPhone cannot (I've also encountered the opposite, but that's another topic). It seems the hotspot functionality only works with connection to a telephone network, and not as a regular WiFi-WiFi hotspot. Do any of you know of a built in functionality that will do this, or an app I can download that will solve this issue for me? Thanks :)
Unfortunately you can't, at least with today's hardware standard. To be able to do that (connecting to a WiFi and tether that through WiFi again), you would need two WiFi beacons on your phone. Since this is not the case, it is not possible to do so.
