At the 2013 CeBIT in Germany this week, Samsung Galaxy S4 prototype cases were leaked before the latest smart phone's big launching event on March 14 in New York City. The Galaxy S4 cases show the bulky size of Samsung's latest creation with a boxier and thicker design compared to the Samsung Galaxy S3.

MyLiving, the China-based manufacturer of the cases, revealed to MobileGreeks that they created the Galaxy S4 cases based from the received dimension details of Samsung's latest smart phone. The manufacturing company further divulged that the information came from Foxconn.

Foxconn has been a famous manufacturing chain in the past couple of years. The company has the capability to put together a number of the high-profile devices in the mobile industry. Therefore, there is a genuine probability that the information they disclosed are valid.

The leaked Samsung Galaxy S4 hard case features the recognizable openings at the back for the camera, flash and speaker. The cases are visibly wider compared to the size of the Galaxy S3. Another noticeable Samsung Galaxy S4 hard case feature shows that the camera is located lower compared to the Samsung Galaxy S3.

However, some may seem skeptical on this batch of revealed Samsung Galaxy S4 cases since it does not really answer the question of what the real Samsung Galaxy S4 looks like. The excited Samsung fans will just have to wait until the smart phone is officially unveiled.

Samsung Galaxy S4 is rumored to feature a 4.99-inch 1080P Full HD display, a quad-core processor, an improved 13MP camera and a number of new software features such as the "Eye Scroll" that can detect eye and head movements in order to scroll on selected applications.

Take a look at the MobileGeeks video below showing the comparison between the Samsung Galaxy S4 cases to the Samsung Galaxy S3 cases as well as the Samsung Galaxy S3 smart phone.
