The USPTO granted Samsung a new design patent which shows a smartphone with no buttons on the front. The patent comes after Samsung was recently granted another patent for a buttonless phone. The first patent may be related to the Samsung Galaxy S5 or the Galaxy Note 4.
The designs in the patent, No. D697,886 S, show a mysterious rectangle on the right side of the device.
The device is rumored to have a release date before MWC 2014, which is next month, or it could also possibly be released in March. Other rumors about the device include a Quad HD (1440 x 2560) display, a new Exynos processor, and at least 3GB of RAM.
