Tech Q&A: Eavesdropping Echo, flammable laptops, switching to Android and more

Want to know more about Amazon Echo, the HP laptop battery recall, ransomware, web printing and switching to Android? I have an Amazon Echo. I am really concerned it is listening all the time. Does it have any privacy settings? A: The fact remains that Echo records all of your commands, and the microphone is always active because the device is always listening for a "wake phrase."
