As detailed by Android Police's Artem Russakovskii, who received a Google Home Mini test unit last week, the device was malfunctioning due to an issue with the built-in touch panel designed to let Google Assistant be activated with a press instead of a voice command.
The Google Home Mini's touch mechanism was registering phantom touch events, causing it to continually record audio, which is not supposed to happen. Russakovskii discovered the problem after finding thousands of recordings in the Assistant section his My Activity portal on the web, where Assistant queries are stored.
Google was alerted to the issue and collected his unit for testing, which led to the discovery of the faulty touch mechanism. The problem as described by Google:
We have learned of an issue impacting a small number of Google Home Minis that could cause the touch mechanism to behave incorrectly. We are rolling out a software update today that should address the issue.To fix the malfunctioning touch panel, Google released a firmware update for all Google Home Mini devices disabling the feature allowing Google Assistant to be activated with a long press. Google told Russakovskii a longer-term fix is in the works, but in the meantime, the press to activate feature will not be available when the Google Home Mini launches.
In response, the updated software disables the long press to activate the Google Assistant feature. Once the Google Home Mini devices receive the updated software, all long press events (real or phantom) will be ignored and Google Assistant will not be invoked accidentally.When the issue was discovered, Google took it seriously and collected the faulty review unit within a matter of hours. An engineer worked over the weekend to figure out what was going on and the firmware update to remove the feature was available by Tuesday.
The company also let me know that they're in the process of building a long-term fix, whatever it may be. It's too early to say if they're going to be able to deal with "phantom" touch events entirely in software or a recall for affected units will be in order.
Introduced last week, the Google Home Mini speaker is priced at $49.99 and can be purchased from the Google website. Google Home Mini units are expected to begin shipping out to customers on October 18.
