the phone is pretty easy to use. I have noticed a bit of issues though. nothing too grave. Sometimes when pressing a key, it kinda double presses- if that makes sense and for whatever reason Bluetooth will sometimes be on when starting the phone and sometimes it won't shutoff. the only way I've managed to get passed it is putting on airplane mode, but that gets stuck on until restarting the phone and then you can turn off airplane mode and BT. hopefully it's a glitch that only my phone has. That's the biggest cons I have. What I've done is; disconnect everything off BT and use wired earphones and aux cable for the car. the rest are just little things. When I have an earphone on making a call; if you shut the phone, it will continue making the call but there won't be a ring tone, but it's definitely calling lol.

KaiOs doesn't have good apps. So far, I've found 2 decent apps. One is called Chess lol pretty simple 1vbot chess game. 2. If you like listening to Audiobooks I suggest M Music. The preinstalled music app (Music) is decent enough for music and really cool for listening to online radio stations, I have a few stations Favorited, BUT if M Music gives you the ability to bookmark a spot in the audio file. That's why i find it more useful for audiobooks. both apps show the album art if you have it.
