Answers to some of your questions about Wi-Fi

• Does my Samsung Galaxy Note® 4 battery last longer if I use a Wi-Fi connection?

  The Samsung Galaxy Note 4 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.

• How can I be sure that my Wi-Fi connection is secure?

  Be sure you use Wi-Fi networks that require password protection.

  Open or unsecured Wi-Fi networks offer no data security.

  Your Samsung Galaxy Note 4 captures the password in the initial setup and remembers it for the next time.

  Without a password, your information is not private unless you're also running software that encrypts data.

• Do I have to re-enter my Wi-Fi provider information on my Samsung Galaxy Note 4 each time I get to a spot where it's available?

  Your Samsung Galaxy Note 4 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 Galaxy Note 4 is in range.

• How do Wi-Fi and Sprint 4G LTE signals interact?

  Your Samsung Galaxy Note 4 uses Wi-Fi first when both Wi-Fi and Sprint 4G are enabled. Your phone searches for a Sprint 4G signal when you travel outside of Wi-Fi range.

• What happens when I leave my Wi-Fi network?

  When you leave a Wi-Fi network, the data session pauses and automatically reconnects to the Sprint 4G network.
