How to Upgrade Google Glass
Just like any other piece of technology, Glass isn’t a piece of artwork that’s meant only to be stared at through a protective translucent box. (If you want to do that, of course, feel free.) Glass is designed to be used — and used so that it enhances the life of the person who wears it.
Google has made updating Glass as easy and unobtrusive as possible. You can do the job yourself or let Glass do the work.
Whether you update manually or automatically, never power off Glass during an update process. If you do, when you turn your Glass back on, you may find that the OS isn’t working properly, and you may also have lost data stored on the device.
Letting Glass Update Itself
Like any other modern OS, the Glass OS can download updates by itself. Glass connects to the Google servers periodically for updates, and if it finds one, the device downloads the update automatically.
Your Glass won’t install updates automatically, however, unless Wi-Fi is enabled and the device is charged. When you plug Glass into the charger, the device updates the OS (if an update is available) while it charges the battery.
Before you charge the battery, be sure that the display is off and that you have a Wi-Fi connection enabled (such as through a wireless router on your home network). If Glass is off, the device will turn on when you start to charge it.
Glass installs OS updates as soon as its battery is 50 percent charged, so you don’t need to worry about fully charging Glass to get updates.
Finding out what got installed
New OS updates may include some new features that you see right away. Other improvements happen under the hood and aren’t readily apparent. Google gives you two ways to find out everything you need to know about the latest (and past) updates: Google+ and release notes.
Get updates on Google+
View the latest information about Glass, including update features, on the Google+ Glass page. If you want to get new information about Glass features before they’re announced to the general public, you can visit the MyGlass page and read messages in the Explorer forums.
Read the release notes
Visit the Google Glass support page. When you open the page, here’s what to do:
In the Exploring Glass section, click or tap Frequently Asked Questions.
A column of FAQ links appears on the right side of the page.
In the FAQ links column, click or tap Release Notes.
The Release Notes page appears, displaying a link to the release notes for the latest version.
You can also view archived release notes for earlier updates by clicking or tapping the Archive link and then clicking or tapping the release-notes link for the appropriate version.
Checking the OS version
Checking the version of the Glass OS that’s installed on your device is easy. All you have to do is tap the Settings card in the timeline and then view the Device Info Settings card onscreen.
The Device Info Settings card tells you whether you have the latest OS, whether an update is available, and how much storage space is available; it also lists the serial number of your Glass.
If an update is available, you can prepare to charge your Glass and update the OS at the same time.
Updating Glass Manually
If you know that the latest OS update is available and you want to get it right away, such as to fix a bug that’s been… well, bugging you, you can. Here’s how:
Open the Settings bundle card on the timeline.
Tap the Device Info Settings card.
Choose Update from the menu.
The update screen tells you that your Glass is updating.
