Similar to Why does HTC Incredible S turn Wi-Fi on by itself?, it seems my Samsung Galaxy Victory will turn on Wi-Fi at random times. It establishes a connection if certain networks are in range (i.e. any open Wi-Fi).
I notice a Wi-Fi setting which allows this phone to keep its Wi-Fi on during sleep, but this is currently disabled.
Is there a way to prevent the device from looking for Wi-Fi networks? If this is specific to Samsung devices, has anyone figured out how to take care of this issue?
After some searching, it turns out this feature is provided by the Sprint network (although that doesn't rule out that other carriers/devices may provide similar functionality). The Q&A at community.sprint.com points to the Sprint Connection Optimizer, AKA the "Intelligent Mobile Network and Wi-Fi Setting." This setting "will automatically connect you to Wi-Fi networks on your device's remembered list."
This setting can be enabled/disabled by navigating to Settings > More settings > Mobile Networks > Sprint Connections Optimizer.
