I did something recently that I haven’t done in over a decade — going a week without using a case on my phones. I think the last time I did that was pre-iPhone with my Motorola Q back in 2006, since it didn’t have a touchscreen that I was worried about getting ruined.
There’s no reason for this sudden change, but I just felt the urge to see what it felt like to not have a case on my phone. My reasons for using cases on some of the best phones I've reviewed haven’t changed over the years, mainly to protect them for everyday wear and tear, as well as those rare occasions when I clumsily drop them by accident. I know others use phone cases to hopefully get better trade-in values for their next phones, but I simply use them for protection.
