Sprint has issued a software update for the LG G Flex that enables voice calls over Wi-Fi networks and a trio of other enhancements and fixes. As per the official release notes (via Android Central), the latest version also comes with a HD Voice icon, security and SMS patch from Google and an update to email signatures. The new software version, codenamed ZV7, will be rolling out in batches from today through July 16th.
Wi-Fi calling enables smartphone users to make voice calls without using minutes against their phone plan or incurring cellular data charges. Sprint customers can use Wi-Fi hotspots to make phone calls and send text messages. The U.S.’s third-largest carrier announced a similar update for the Samsung Galaxy S5 a few days ago, while the feature is also supported on the Samsung Galaxy Mega and Galaxy S4 Mini.
