We have two S4 mini phones and the WiFi on both of them stopped working! Not Happy right now! Tried the Chat and No Representatives are available, and there is no support email address! Please Advise! Both phones show they connect to WiFi but nothing will load, Aps or Web. Have tried different WiFi networks that I know are working. Have tried a Factory Reset and that did not work either. I am now updating the phone after the Factory Reset.
