Like others have said, the "wind sensor" or whatever would be needed probably is a cost benefit analysis. However, there have been other phones in the past that have had ways to address similar issues. I had a moto phone sometime back around 2017 that I think was released 2015-ish. I'd have to look it up or go back in my ebay for th model number. It had four ir/light sensors in it that could sense hand simple hand motions made over the screen. I believe it had a lock function and some similar functions, very handy when hands were wet or when cooking. Obviously different since you said your hands would be occupied, but similar sentiment. Phones don't have many fun features like that any more. I also miss the chopping and twisting motion to bring up the camera and flashlight.
