The update that’s set to begin its roll out today brings Galaxy S5 users to software version G9001ANE5. According to the official update page on Sprint’s website, -Fi calling is the only change within the update, which will be good enough for most. ile the feature is pretty self-explanatory, those unaware of what -Fi calling is just need to know that it enables someone to make calls over -Fi. This is especially useful when your carrier’s coverage is spotty (like deep inside a large building). There are other ways, via third-party applications, to give your phone -Fi calling powers, but they often require the other party to have the same app or service, or they give you a different phone number than the one associated with your phone. The Galaxy S5 joins the Galaxy S4 Mini, Galaxy Mega, Galaxy Note 3 on the network. Here’s to hoping Sprint can fast track the device support for -Fi calling. Now we’re just waiting to see how long it will take Verizon AT&T to catch on.
