Mens shorts also have small pockets. I bought a Galaxy Flip so I could still have a phone in my pocket when wearing shorts. (yes, I have both iPhone and Android phones)Some men's trouser pockets, especially suit pockets, and even jeans pockets, can struggle with modern iPhones. Maybe properly made, square bottomed pockets will come back into fashion.
Don't even speak about women's trousers and their silly little pretend pockets haha
