This week new users of the Samsung Galaxy S7 and Galaxy S7 Edge are finding that they've got an extra option in their Mobile HotSpot settings. Instead of just being able to share their mobile internet connection, they're now able to bounce their Wi-fi connection from their smartphone to their laptop - or any other Wi-fi-enable device. What's the use of this? Why would you want to share a Wi-fi connection to a device when that device already has the ability to see a Wi-fi connection? Funny you should ask!
