For a time, Google Glass was a singularly innovative product that was put in the hands of developers and early adopters. Those days are over now that a handful of companies are working on producing similar technology, and with Google Glass having taken a step back and revised its strategy, design, and target markets to focus more on enterprise. The popularity of Google Glass may have died down within the consumer community, but there are still plenty of users out there who enjoy their units and are getting a lot of functionality out of the face-worn AR technology. A recently reported issue however, seems to be making Google Glass units otherwise unusable.
While not every single person who still has a Google Glass Explorer Edition unit has encountered the issue, a server problem reported by a decently sized and growing collection of users on Google+ mentions that Google Glass units are resetting themselves. The bigger issue is that once the reset took place, users have been unable to reconfigure their Glass making them completely unusable. This poses a major problem for anyone that still owns Glass as acquiring them was fairly expensive. This also isn't a completely brand-new problem as users have been reporting it since the first week of January.
Other users have reported a completely separate issue when trying to view Maps and Calendar cards, stating that instead of being able to view the information on those cards they are told their Google password is incorrect. While both of these issues are alarming, the reset issue more so, the good news is that Google is working to fix the problems with the server that is causing these in the first place. The other good news is that this has nothing to do with the hardware according to Google, so users shouldn't have a need to worry about that. While the fix won't be immediate, Google states that they should have things up and running and resolved within a few days, which means any Glass users who are experiencing either of these problems should see things go back to normal by the time the weekend rolls around.
