The HTC One M8 on Sprint is receiving an OTA update that bumps the software up to version 2.16.651.4, and also includes Android 4.4.3. While the changelog only mentions “Network acquisition enhancements (voice/data)” – just like the last OTA update – one very helpful nugget is the inclusion of WiFi calling, which Sprint has slowly been implementing across its entire Android line up.
WiFi calling now allows for customers to place calls wherever they have a WiFi signal, even abroad – something Sprint blocked until very recently. In many cases, this means that Sprint (and T-Mobile) customers will now be able to place calls and send texts in areas where even Verizon and AT&T customers cannot. WiFi calling also replaces the need for Airaves or other signal boosters, since anyone with a WiFi router should be able to make calls.
Following this update, users should also notice an HD voice indicator when they are indeed making HD voice calls. While the update doesn’t include Android 4.4.4, it’s still nice to see HTC relatively ahead of the curve when it comes to software updates.
If you get the update, be sure to let us know how it’s working out for you – and if it solves those annoying “click” sounds that some people are experiencing.[Sprint]
