T-Mobile HTC One M7 Expected To Receive Android 4.4.3 OTA Update With Wi-Fi Calling Enhancements Tomorrow
T-Mobile has long supported Wi-Fi calling, a feature that lets users circumvent a poor mobile connection by tapping into their home network instead. It's functionality that another carrier only started to implement just this year. This update should somehow improve the experience on T-Mobile's version of the HTC One M7.
As for Android 4.4.3, it's a bugfix release, so don't expect anything in the way of visual changes. For the details, check out some of our previous coverage.
