  Galaxy S4 Render with full specifications list.

A new accessory that will be released for the Samsung Galaxy S4 will help owners of the smartphone take better care of their health.

This device comes in the form of a pad that measures pulse and blood pressure. By keeping track of these two bodily functions, Galaxy owners will have a better idea of just how heart healthy they are.

Samsung is also expected to launch a health-related application that can sync with this new device and monitor the results. The move by Samsung could potentially catch on with the rest of the smartphone world and other companies such as Apple might release a device with these capabilities as well.

The specifications for the Galaxy S4 have not been confirmed yet, but new pictures of cases made for the device which surfaced on a U.K. site this week could provide hints on what it will be like.

The site, known as mobilefun.co.uk, claims to have received these leaked cases from Chinese suppliers who appear to know enough about the device to begin making accessories for it.

Judging from the look of the cases, the smartphone will have either a 4.99-inch or 5-inch display, which will most likely be at 1080p Full HD resolution. The cases also indicate that its camera will be mounted in the middle and the device will also have rear speaker on the side of the camera. The headphone jack and lock button are located at the upper right, while the volume buttons are located on the left side. The micro USB is at the bottom.

The Galaxy S4 is also rumored to be featuring a Qualcomm Snapdragon chipset instead of the Exynos 5 Octa it was originally expected to use for power.

This rumor was taken from a South Korean media site that stated that Samsung's new Exynos 5 Octa-core chipsets would consume too much power and generate too much heat if used to power the company's next flagship smartphone.
