Basically, it "senses" wifi spots. It can either turn "on/off" wifi at your "favorite" places. It can even "automatically" sign into wifi networks by automatically entering your information and accepting websites "terms and conditions".
Wifi spots like at libraries, restaurants ,etc.
Yes and just tap on wifi sense in settings/wifi for the options....Does it really tag WIFI Hotspot in the Map?
and, how is it possible to share this wifi to my CONtacts?
