How often do you change your cell/mobile phone case/cover?

Didnt need to replace my Spigen case yet. It's called Tough Armor for a reason.

Had the same phone for 8 years now. Never had a case for it, never will. You can't break this beast.

Never. If you're worried about the frame of your phone, you probably should wear a helmet when leaving your house. I do neither of those.

i hate cases. ^^ i have my current iphone for nearly 3 years now, and it's still alive. so i don't think i really need one.

I'm just using what comes with the phone. Instead of buying an expensive phone that I have to be careful with, I try to go for a cheaper one, which means that if something bad happens to it, it's not a big deal, and I don't bother buying a protective case. Only ever broken one phone, and it was one of the old ones, with an antenna sticking out (and it was the antenna that broke, so a case would not have saved it).

I use belt holsters because I hate having a phone in my pocket. Henceforth, until I get a dual SIM phone, my current company phone travels in my bag. So, I bought a simple semi-transparent black silicone cover for it so it doesn't get scratched. But that's as much as I want to care about its looks. :)
