But why? Why exactly a day before the 9:00 AM public American availability of Google Glass, would Mountain View decide to render the video calling feature null? That’s because fewer than 10 percent of Explorers were using it; thus it was deemed unnecessary — until it can be further developed or revamped.
Meanwhile, Android 4.4 Kit Kat, the latest version of the mobile OS, is now integrated into Glass, and offers new features that can be added to apps and let developers use the latest SDK. Meanwhile, the end-result is that users will be able to see organzied photos in bundles (for easier scrolling), allows for photo replies in Google Hangouts, and puts most-used voice commands at the top of the list.
