I’m not being funny. I treat every phone I’ve ever owned as the expensive devices they are. I buy a protective case, don’t put it in my back pocket where it can be bent or broken. I don’t use it while standing over the toilet so it can’t be dropped in. When I drink with friends, I don’t lay my phone on the bar where some drunk can spill beer on it.
It’s more than being able to have the use of a fully functioning device, at trade-in time my phone is worth more because I take of it.
