We hold ourselves to high standards for the features that we build, and video calls aren't living up to these standards. Explorers have told us so directly, and fewer than 10% of them use video calls. For this reason, we've made the hard decision to remove video calls from Glass until the experience is better. We don't know when that will be, but in the meantime, keep an eye on MyGlass as more Glassware is built and released – we're already seeing the developer community work on other video streaming services. We've always said that feedback from Explorers shapes Glass, and this is no exception.
