Do I need a foldable phone? No. Do I like the idea of owning a phone that is actually small enough to be used with one hand and can fit anywhere? Yes. Besides, closing it to end a call is very cool.
The ones I have seen in stores are still too long to be used with one hand or fit comfortably into a pocket. My Pixel 7a is about the biggest I can use one-handed, and even then there is awkwardness.
Most Androids have a one-handed mode, where it shrinks the display into a corner, so you can reach everything with your thumb.
I had to go crawling back to Samsung because the pixel 9 is too large (and heavy) for me. I was using a pixel 5 before my screen died earlier this year :(.
Edit: to clarify I’m not using a foldable phone, I just have their S24 which is apparently the smallest phone on the market I could find these days that isn’t out dated (Zenphone).
Those are probably the Samshits and I too avoided them because they’re too damn long (And their user hostility lol), the Pixel 9 Pro Fold is what you want, folded it’s almost as big as the 7as screen (6.3 to 6.1 on the 7a)
First - 6.3 usually means already over the edge of comfortable, 7a is already almost too much. Second - thickness adds to it when it’s in your hand. And third - why would I spend huge money (doesn’t seem like it would decrease in price with generations as much as a normal phone, it might be EOL when it becomes affordable) on something that breaks more easily and is still bigger?
