The squeeze functionality on HTC’s U11 and Google’s new Pixel phones is undeniably odd, but HTC’s implementation has the advantage for one reason: the U11 lets you map the squeeze to different functions, while the Pixel 2 only silences calls or summons Google Assistant. Well, not any more, as an app named Button Mapper now lets you remap the squeeze feature in the new Pixel handsets.

XDA brought the app to our attention, and points out that you’re not really re-mapping the function. Instead, the app is intercepting the instruction to launch Assistant and dropping in another command in its place. It’s hacky, but it works.
