Sure, it’s useful to have your digital assistant ready to help you out with just a verbal command to turn it on. But Google was forced to issue a software update recently after some of its new Home Mini devices started waking up thousands of times a day on its own, and recording any and every sound it heard.

According to Artem Russakovskii over at Android Police, the review Home Mini he had in his house would randomly wake up, record, and send the recordings to Google. He says he noticed it after he was trying to watch a TV show, and the Home Mini turned itself on several times a minute, listened to the show, and then tried to respond.
