I change whenever my phone gets too slow or enough compatibilities crop up. My first smartphone was a Galaxy S2 in 2011, and that lasted me until 2015, when I got a Galaxy S6, which I'm still rocking today. Got no reason to change yet.
Before smartphones, the only phone was a Nokia... I wanna say 1600. Got that as a Christmas gift the year it came out, IIRC.
