Not really. When my dad wanted to buy a phone, it was either a Samsung or something else. iPhone never entered the conversation. When my mom wanted to buy a phone, she just got the same thing as my dad so they could help each other. Same thing with my sister and her husband.
My wife used a Samsung Galaxy S3 and then an S5 for the last five years or so. She never even thought about getting an iPhone until recently when I convinced her to do an experiment with me.
You know what every single one of those people that I just mentioned cared about most in their phone? "Having a big screen." And when they first started looking, iPhones all had tiny screens, so they didn't even consider them.
I personally also never even considered an iPhone until very recently when I decided to just try it out for kicks. It's a decent phone. I miss that back button though. Navigating back in iOS is tedious and I think iOS is total shit in a lot of ways, like not letting me absolutely position the home icons or even letting me replace the home screen.
