The buttons on smartphones don’t change very often. We’ve lost the physical home button, but other than that, it’s been consistent for a long time: A power key and volume buttons.Lately, some companies have started to spice things up with new buttons dotted around their phones, and while some are great, dedicated AI buttons are not. After an extended period with the Motorola Razr Fold, I believe it’s high time Motorola (and others) killed off one of my least favorite smartphone trends.
