The latest leaked accessory of a highly anticipated gadget is a black snap-on case that claims to be compatible with the Samsung Galaxy S4. CellJewel.com has started selling a Samsung Galaxy S4 Snap On Case. The site also posted a video on YouTube showing off the case — minus the Galaxy S4, of course.

The website's order page shows what appears to be an altered white Samsung Galaxy S3 inside the case, and the product description of the case says:

"Snap On Cover is custom designed to fit perfectly and protect from scratches and other elements without adding bulk. The polycarbonate material used enhances the case by adding rubberized texture to increase grip and durability. The Snap On has precisely made openings to allow access to all buttons, charging ports, headset jacks, speakers, and cameras. Flip and slide actions of the phone are not affected, enabling the snap on to remain on the phone for proper usage."

After the site posted a video of the case on YouTube, people began commenting and questioning the validity of the case. Some commenters pointed out that the rear camera and LED cut-outs on the case don't match the hardware positions properly. CellJewel.com responded to the comment by saying:

"We buy our cases from manufactures that get the exact specifications for the phone from Samsung themselves. We buy and resell on our website and from any research this company has done this case matches every port and function available on the phone. If you buy one and it does not fit we will refund it or exchange it for one that does. So this is not a scam."

If the case is in fact real, it wouldn't be the first time accessory makers have revealed designs of unannounced devices. Accessory makers for Apple products are notorious for leaking cases that have ended up being legit. If you want to take a chance on this case, you can purchase it now for $9.99 and it's available in multiple colors.
