Nothing phone is all about simple designs, budget friendliness, good performance and aesthetic appeal.
I think if nothing phone really went into designing of a flip phone they won’t just focus on the durability but also it’s versatility, think about outside display use but, key display but stil have a touch screen and on the side of the key display you have more optional buttons.
Idk I just know they can push the idea of a good performing phone like that a bit further.
