Using a Bluetooth-enabled phone
While Glass should work with most Bluetooth-capable phones, for best results, we recommend using Glass with an Android or iPhone phone.
For phones that support Bluetooth connections with Glass, pairing your Glass to devices via Bluetooth lets you make and receive calls hands-free. Since many of Glass' features depend on the Internet, tethering your smartphone (where available) is highly recommended. For example, tethering Glass to your iPhone with Personal Hotspot lets you share your phone's data connection for Google searches, directions, sharing pictures and videos and more.
