Let's see. What might you even do on your phone? Browse twitter, rot on TikTok watching videos of people more attractive than you live more attractive lives, watch a movie occasionally. Take a selfie of...oh, yeah, ugly.
The only thing that matters with each generation of smart phones is their cameras, and unless you like taking photographs of things other than yourself on a whim, I don't see a point. And if you're not doing it on a whim, spend the money on camera with a bigger sensor and bigger lens.
