This week has given us so much to talk about Samsung's upcoming smartphone. And Samsung's Galaxy S4 is now becoming one of the most rumored devices.

So far it has been the release date, processor, display and other technical details of the smartphone, but now the rumors have reached its accessory part too.

A UK-based Web site Mobilefun has posted a series of pictures allegedly of the cases of Samsung's next smartphone under the Galaxy series.

The report says that the images are sourced directly from a "trusted Chinese accessories manufacturer."

"What can we learn from the images below? Well, we can see that the phone does look to sport a 4.99 or 5-inch display, likely at Full HD resolution. The overall shape of the phone looks much more angular than the previous generation, and has more in common in this regard with the earlier Galaxy S2 smartphone," the report adds.

By looking at the case design we can say that Galaxy S4 is going to have a flash for the rear-facing camera and at right side of the camera the speaker of the phone will be placed.

The charging point looks like a USB connector at the bottom of the phone and a 3.5 mm audio jack.

This is the second time an accessory of Samsung Galaxy S4 has come into news. Just a day back a black snap-on case allegedly designed for Samsung Galaxy S4 was seen in tech reports. The case is available on CellJewel.com for $10.

"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," product description of the case states.
