The Connection Optimizer is a useful tool for helping to manage data usage by allowing the device to automatically switch from the mobile data network to Wi-Fi. When available, connecting to Wi-Fi can offer the following benefits:
From the home screen, use two fingers to tap and drag down the Status bar.
Tap the Settings icon.
Tap Mobile networks.
Tap Connections Optimizer.
Tap the Connections Optimizer box to turn the feature on or off.
The Connection Optimizer settings are now changed.
Note: Many public Wi-Fi networks require a user to accept their End User License Agreement (EULA). The device will keep track of these sites for easier access. To clear the list of saved sites, tap Clear EULA acceptance data, then tap Remove All.
