It's unclear if it is a deliberate ploy on Samsung's behalf to drum up interest in its new smartphones, but considering the amount of leaks we have seen of the Samsung Galaxy S7 and the Galaxy S7 Edge in recent weeks, there will be very little for the company to announce on February 21 at Mobile World Congress.

Samsung is widely expected to showcase the Galaxy S7 and Galaxy S7 Edge at MWC in Barcelona in 11 days time and following a plethora of leaked images and specs in recent weeks, today we have a couple more to add to the list. The first comes from Spanish website Pisapapeles who managed to get their hands on a gold version of the Galaxy S7.

As you can see in the pictures, the design of the new device is not much different from the design of last year's model. One change sees the 5.1-inch screen extend even closer to the edges of the phone. Pisapapeles also notes that Samsung has continued using a microUSB port on the Galaxy S7 rather than the up-and-coming USB-C port which many smartphone manufacturers are using for data transfer and charging.

Moving to the Galaxy S7 Edge, the curved screen version of Samsung's flagship smartphone, French website Nowhere Else has published leaked press renders of the new device, showing off a new gray color option which was not available on last year's model. Again the device is pretty similar in terms of design to the Galaxy S6 Edge, though this year Samsung has chosen to use a 5.5-inch screen rather than a 5.1-inch screen.

As well as re-introducing a microSD card slot, Samsung is expected to boost the battery life of the new smartphones to two days, incorporate the latest Snapdragon 820 chip from Qualcomm and make them water and dust resistant.

Samsung's press conference on February 21 will reportedly come just weeks before the Galaxy S7 and Galaxy S7 Edge are expected to be released to customers as Samsung attempts to regain some of the losses in market share it has experienced in the last 12 months.
