Google will 'fix' the Pixel 2's hidden menu button
By 'fix' we mean 'patched out in the near future.'
Looks like the Pixel 2's "secret" menu button was just leftover code, after all. Google has confirmed to CNET that this was a bug, not a feature, and that it'll be patched out in the future. If you're still enjoying that new phone smell, open up the settings menu and double tap in the lower right while you still can.
