Samsung is known for cramming a lot of different features on its Galaxy smartphones, some of which are cool and many of which are gimmicks. However, Samsung may be cooking up a new feature for the Galaxy S5 that could help further separate it from the Android pack. Galaxy Club has spotted a new document filed with the Korean Intellectual Property Rights Information Service that details a new built-in multi-party video calling system that could come pre-installed on future Samsung devices. SamMobile notes that it seems as though the feature will let video callers “use both the front and back camera at the same time when in a video call conference, while also being able to see the video feeds of others at the bottom of the screen.” From the pictures shown in the document, it looks like the video calling app will support at least four different users at once.
