Tiney Tether

This is a "shortcut" icon for one of the screens to allow you to quickly turn on/off the tethering options. This will NOT bypass your carriers requirement to pay more for this option. It is solely to make turning the option on/off faster and only works if you have the service available from your carrier. First screen shot is the settings screen it takes you to on a galaxy s6, second screen shot is on an old LG.
