Well, I'm using an HTC phone from 2014. I haven't had to change or repair any parts and it costs about half an iPhone, I think. To clarify, everything seems to be working just fine.
Unfortunately, Google. But that's the only problem with it. I was actually going to stick with a flip-top but then I started working as a dev and figured that getting a smartphone would give me some extra cred.
Nowadays it's probably the other way around, I should probably dig out my old fliptop and use that, to show how 1337 I am.
