Of the two options, "hotword" and "physical touch", I'm surprised at which was disabled to prevent false positives!

If they'd disabled hotword, then the phantom physical touch would still happen, so literally nothing would've been solved.

Sorry I wasn't clear enough making my point:

I'm surprised that the implementation of a (simple) physical button was done badly.

I'm surprised that the (surely more difficult) hotword detection works so well.

My guess is that location could have helped trigger the defect - assuming they're using a capacitive touch button, then moist environment of a bathroom isn't exactly helping (doesn't change that it's an implementation issue, though).

Capacitive buttons are also highly sensitive to noisy ground busses. A cheap power supply can make one go haywire.

Want to bet the developers all had good clean power while the production units got cheap Chinese bricks?
