I purchased the FoxFi app and was working fine on my Galaxy S4 for over a month. UNTIL YESTERDAY'S Samsung galaxy S4 system update. I spent hours with Verizon tech support and they Verified that the app is now broken due to latest Samsung System update.* PLEASE FIX THIS BUG AND ROLL OUT AN UPDATE ASAP. All Verizon customers with Galaxy's are dead in the water for ANY tethering wifi app.
