I have a 3x3 flip phone, it's not a smartphone but it has some modern features like voice to text, internet browser, predictive text. It has a 2 megapixel camera and its own selection of apps.
One specific app that stands out is that they remade Fruit Ninja for it for some reason and instead of using a touch screen, each fruit has a giant number stuck to it and you have to push the number's key to cut that fruit, it is ass to play and I got 0 fruits on my first try because it's really hard.
There's also Jetpack Joyride but with no cosmetics, no bg changing or scientists, only 2 types of lasers, and sometimes you fall through the floor which makes you unkillable until you fly back through the floor.
I don't remember why I have picked a flip phone, I have a really bad memory but I know I had a reason.
I wanted a cute one but could only find plain black ones for sale, I put some cute stickers on it though.
