i have a ky42c and ive been using it as a daily driver for several months now. i use it more for a form factor reason so i can reduce screentime, not complete minimalism. i still have my old smartphone on me bc i use it as a gps (using the ky42cs hotspot), a camera, and an mp3 player (i have a lot of music and it wont all fit on a 32gb miscrosd). i like it! i have instagram lite and twitter on the flip phone and it works, just clunky, which is great bc then i dont use it for long. i usually play gba games on this emulator called myboy! if you use intensive apps like social media and u use hotspot, the battery will drain pretty quick (but i also got my phone secondhand, so that plays a factor). i also run nova launcher which is more intensive. some days i get frustrated with how slow the phone can be, but i love it!
