I immediately put a transparent case around my device as soon as I get it and put a screen guard on it as well. My wife mocks me saying that it totally kills the device's looks but considering how integral having a functioning phone at all times is to... well, existing (and accessing any Govt. service in my country), I take the hit in aesthetics for extra durability.
As a result, all my phones end up looking pristine several years into them being used.
