I have found a way to bypass that annoying FoxFi lockscreen on my Verizon I545 GS4! If you have FoxFi "Already" installed follow these steps:
(1) Press Home button-->Settings-->More-->Security--> Trusted Credentials--> User--> FoxFi--> Scroll down and select Remove-->Home Button.
(2) Re-Start FoxFi App--> Install certificate "BUT" on "Credential Use" select "WiFi"--> Ok-->Ok again-->Enter PIN #--> Turn on Mobile Hot Spot and leave on-->Home Button--> Shut screen off w/pwr button-->Home Button-->Enter PIN #-->Menu--> Settings-->My Device-->Lock Screen--> Enter PIN # for the "LAST TIME"-->Then hit Swipe (no security) and Boom...You're Done!
(3) Now you can turn FoxFi On or Off and don't have to worry about that annoying lock screen...Enjoy!
PS...If that annoying "Warning Triangle" happens to show up (it may not show anymore) just-->Swipe down on the notification panel and press clear if you don't want to see it while FoxFi is on!
Anybody else concerned about the warning about VPN and third party traffic monitoring, etc? I mean I get it, I do IT for a living so I know what this *means* - Anybody else concerned about that part? I guess I'm not because I have a glass of Kool Aid too - just wondering...
