The Samsung Epic™ 4G uses less battery power with a Wi-Fi signal than the Sprint networks.
Note: Battery life depends on network conditions, your actual usage, and a number of other situations according to Sprint internal testing.
Be sure you use Wi-Fi networks that require password protection.
Open or unsecured Wi-Fi networks offer no data security.
Your Samsung Epic 4G captures the password in the initial setup and remembers it for the next time.
Without a password, your information is not private unless you are also running software that encrypts data.
Your Samsung Epic 4G can remember an unlimited number of available Wi-Fi networks. It's easy to add new Wi-Fi networks. The new network is ready to launch when your Samsung Epic 4G is in range.
Your Samsung Epic 4G uses Wi-Fi first when both Wi-Fi and Sprint 4G are enabled. Your device searches for a Sprint 4G signal when you travel outside of Wi-Fi range.
When you leave a Wi-Fi network, the data session pauses and automatically reconnects to the Sprint 3G or Sprint 4G network.
