Edge Sense has always been a gimmick — but who can blame HTC for embracing a gimmick. The company’s mobile division has been struggling in recent years, so why not embrace the novelty of a squeezable side input? The tech got a bit more support when Google embraced it for the Pixel 2, renaming it Active Edge in the process.

With today’s announcement of the U12+, HTC is introducing Edge Sense 2. The company promised it would keep updating the feature, and this new flagship is starting to making it that much more compelling. The second generation doesn’t make it an essential feature, but some key additions point to how more sensors on the sides of the handset could turn it into more than just a glorified additional button for the phone.
