When I had my six month affair with an Iphone 6 it took me a month (I don't get many calls) to finally get frustrated enough to google "How to reject calls" because I was so used to Android giving me a big red X that I never even considered pushing the power button to reject a call (I think that even just mutes incoming calls on Android, I forget), that X let me mute or reject based on the direction I swiped it. I could only figure out how to mute the rings which means my car radio would just be silent until the caller finally gave up.

I know a lot of iphone users think it's the most intuitive machine in the world and a 5 year old can get it, and I'm obviously heavily swayed by my decade or whatever with Android but the amount of hidden/unintuitive-to-me/impossible-to-do things I found was what moved me back to Android after that trial.

I spent a LOT of time searching on Google for how to do things with that phone.
