It may not technically be the latest version of Android, which is currently Android 4.4.4, but HTC One (M8) users on Sprint will be pleased to hear their devices are receiving a minor update to the next best thing, plus a few other goodies.
The new firmware released today, 2.16.651.4, is based on Android 4.4.3, which packs miscellaneous improvements and fixes. In addition, the update adds an HD Voice indicator and support for WiFi Calling.
Own the Sprint variant of the HTC One (M8), but don’t see a notification to update? Not to worry! Sprint typically rolls these types of upgrades out gradually.
Still, if you would like to manually check for the update, navigate to Settings > About > Software update.
