Voice Activation on Google Wear OS Broken For Months 2 months ago Google Wear OS users have grown increasingly frustrated with Google after months of voice activation not working on their smartwatches. Wear OS makes use of Google Assistant, with the ability being one of the main selling points. Reports starting showing up on the Google Issue Tracker back in November, with scores of people complaining of being impacted by the problem. The issue spilled out onto Reddit Wednesday, with the thread already amassing hundreds of posts. Users are still able to use Google Assistant, but doing so requires using the touchscreen or a long-press on the power button. Needless to say, this makes interaction much more difficult in situations where a person is active and unable to physically interact with their watch.
