What it does
Secure Wi-Fi encrypts your traffic and hides it from trackers when you use public or unsecured Wi-Fi, and can switch on automatically in places such as cafes and airports. Samsung offers a free monthly data allowance and paid unlimited plans, all tied to your Samsung account. It is found under Security and privacy in Settings and runs only while protection is on.
If you disable it
Secure Wi-Fi protection is no longer available. Other VPN apps work as before.
