I rarely use a smartphone, but I do use a Samsung Galaxy S7 as my phone.. for, phone calls and txts, as an mp3 player, as a GPS when driving and hiking, to read books on when in a waiting room or something. That's about it. I smashed up my last one and had to buy a new phone. My requirements were... * Not too big (S7 is bigger than I want already) * audio jack * micro sd card slot * Some waterproofness * nice screen (eg. oled) that I can see in direct sunlight I ended up buying another new-old S7 as I couldn't find any new-new smartphones that fit my requirements.
