As you might see in the iPhone thread, I've just bought one. The Libre app is working perfectly except for the fact that my current sensor is still reluctant to connect or stay connected. Once I get it downloaded to the phone by bringing them into physical contact it will stay connected and update the reading as necessary until the phone screen shuts down, currently set to 5 minutes - then only another physical contact will get me off the loss of signal screen. Two phones, same problem - its definitely a faulty sensor. My non-techy mind is wondering if this sensor has a faulty battery? Eight whole days until it expires and I can replace it...
