Apple has updated the Wi-Fi Assist feature in iOS 9.3 to show exactly how much cellular data is being actually used when the feature is turned on.
Apple has been hit with a class-action lawsuit in the state of California over the integration of the new Wi-Fi Assist feature that makes an appearance as part of an iOS 9 installation, and is on by default. The lawsuit, which has been brought against Apple by plaintiffs William Scott Phillips and Suzanne Schmidt Phillips, alleges that Apple as a company didn't do enough to explain what the Wi-Fi Assist feature is and how it actually works, resulting in overcharging of cellular data plans.
