Editors' note: This post was updated December, 2013, with two new products from Lifeproof and Seido.
iPhone owners have always had a variety of cases and covers to choose from, but the Samsung Galaxy S3 and S4 are among the few ultrapopular Android smartphones that have spurred cottage industries of cases and covers.
In boiling down the best of what's currently out there, I tried to provide a good mix of well-designed, affordable cases with more-expensive models that offer some unique attributes.
One thing to watch for when buying cases these days is that you can come across pricier products from better-known brands that sell under unknown brand names for much less (yes, factories in China are churning these out and the same reference designs appear to be available for purchase for whomever comes along and buys them).
While higher-end cases tend to cost from $30 to $50, perfectly good cases can be had for less than $10 shipped.
Of course, when it comes to protective cases, personal taste is a big factor (and plenty of people don't bother with them), and we may have missed a few that you think should have been included. We'll be updating this list as more products arrive, so feel free to make any suggestions or criticize our picks in the comments section below.
