This is your basic thermoplastic polyurethane (TPU) case that also has a built-in kickstand, which comes in handy for watching video. One small design note worth pointing out: with the kickstand folded back into the case, the back of the case isn't completely flat. The Colorsplash is also available in a red and a translucent version.
While Cimo's Gloss Back isn't terribly fancy, it makes the list because it's slim and simple, has a nonslip texture (it's grippy), and costs around $9 shipped. It comes in multiple colors, but we're highlighting the translucent model.
For those of you who wear your Android love on your case, the well-priced CruzerLite may be right up your alley. Comes in multiple colors, but I'm a little bit more partial to the translucent green case.
If you plan on watching a lot of videos on your S3, you should probably take a hard look at the Elsse Super Premium Folio Case with Stand. It has a folding origami-style flap that converts into both a horizontal and vertical stand. Available in multiple colors.
Incipio makes a few different Silicrylic models that come in various colors. The DualPro Shine is a bit of a slicker version of the case, but you can save a few bucks by getting the standard Silicrylic, which also has a silicone interior wrapped in a hard-shell exterior.
JKase's Slim-Fit Streamline is your basic thermoplastic polyurethane (TPU) case that's inexpensive and distinguishes itself with some added grippy texture along its edges and a wave design on the back. It comes in multiple colors. This case is also sold as the BoxWave DuoSuit, but the BoxWave version costs more.
I liked iSkin's Aura, which is also available for the iPhone 4/4S and other smartphones. With its two-tone aluminum back shield, it's certainly a sleek, eye-catching case (it comes in three color combos) and has a slim profile. Its only downside is its relatively high price.
For its Vibes line, which comes in multiple colors, iSkin touts its Microban antimicrobial protection, which "helps prevent the growth of bacteria that can cause stains and odors." I'm not sure I've ever had a smartphone case with a B.O. problem, but hey, it makes for good marketing.
This one's a bit overpriced, but it is slicker than your average TPU case.
The MiniSuit Versatile Case Cover + Stand + Book Folio Wallet is a faux-leather wallet-style case that offers excellent protection and has slots for credit cards inside the front cover. I didn't try this model but I did try Spigen SGP's nearly identical Illuzion, which retails for about $20 more. The only small issue I had with the case is that you really can't stick too much stuff inside the slots before it gets hard to close the cover. So, it's really just designed to hold a credit card or two, a driver's license, and some maybe some carefully folded $20 bills.
This is Samsung's official flip-cover case for the S3. It's a nice, thin case that offers good protection. Its only fault is that, at over $30, it's pricey for what it is. Available in multiple colors.
Sena makes a few different cases for the Galazy S3, including the Classic Flip (pictured) and the Magia Wallet, both of which are availabe in a few different color options. While the company's cases are made of high-quality leather, their only drawback is that they're expensive.
Speck makes a few different GS3 cases, including the Pixel Skin HD (pictured top right) and the popular CandyShell case, which you can see protecting plenty of iPhones. The CandyShell (pictured at bottom) comes in multiple colors and fits very snugly onto your phone. The inside is made of soft rubber, whereas the outer shell has a smooth plastic sheen that gives it a striking look.
While the list prices can be high on Speck's cases, you can usually find them for significantly less on Amazon. For instance, the CandyShell lists for $35, but can be had for closer to $20, depending on your color choice.
Spigen SGP makes several nice but somewhat pricey cases for the Galaxy S3. The first I'm highlighting the Argos, which is one of the slickest flip-cover style cases available for the GS3. It's available in multiple colors, including white and vintage brown, and is made of leather.
Spigen SGP's Ultra Flip is one of nicest cases out there with a horizontal flip cover. That cover is made out of leather and the slim plastic case has a leather back glued to it (hopefully, the glue holds up over time). It's fairly pricey but it's a very slick case and comes in a few different color options.
