Samsung Galaxy S 4 cases and flip covers appear online
Although at this time nobody knows for sure what the Samsung Galaxy S 4 will look like, accessories for it have already found their way to the listings of at least one online retailer. Mobile Fun in the U.K. is now accepting pre-orders for a variety of protective Galaxy S 4 cases, including hard polycarbonate shells and ones made of flexible materials, via its web page. Furthermore, the retailer is expecting to start shipping genuine Samsung Galaxy S 4 flip covers available in a number of colors, including orange, pink, blue, mint, white, and black, in about 2 months.
However, the shape of the cases you see in the images does not necessarily match that of the upcoming Samsung Galaxy S 4, although some of them are probably close. You see, sometimes accessory makers just follow the rumor mill and come up with prototype cases based on leaked designs. That's why some of the cases below would fit a Samsung Galaxy S 4 if it looked like this, while others would fit the device if it looked like that.
So yeah, you are free to spend $15 on a case for a smartphone that hasn't been announced yet, just don't expect it to look exactly as it does on the images. Or perhaps a better idea would be to wait another day until the Samsung Galaxy S 4 is finally unveiled officially prior to reaching for your credit card.
