I had flip phones before smartphones became default, I loved the intuitiveness of answering, locking, etc, and I love the idea of a foldable smartphone because of the size of the screen that you can get into a pocket

Same here, was on flip phones for the longest time. I loved the compactness. They became scarce some years ago so I started buying smart phones, currently a Samsung. That thing is huge and unwieldy. It does not fit well in a pocket so I don't carry it around. I always have to find someplace to stow it, often in the center console of my car.

A folding smart phone could be a solution, but they're all really expensive. I don't spend a lot on phones and never will. Right now I'm looking to replace my under $300 Samsung with an under $300 Motorola. Functionally my Samsung works well, but I hate all the Samsung bloatware on it. I know Motorola uses a fairly stock Android image and hopefully it will be a bit more compact.
