How do I configure the 4G settings on my Samsung Galaxy Victory™?

Your device allows you to decide how your device connects to your wireless carrier's network. To edit your device's network settings, open the Notification Panel by swiping your finger from the top of the screen to the bottom, and touch Settings > More settings > Mobile networks.

Touch Sprint Connections Optimizer to set your device to connect automatically to the best mobile network: Wi-Fi® or your carrier's network.
