Samsung’s next gen Galaxy smartphone, the Galaxy S IV may be unveiled at CES 2013, which happens in January, or at MWC 2013 (Mobile World Congress) that takes place in February. If rumours on the Internet are to be believed, the Korean giant's next smartphone is expected to feature a 4.99-inch display with a resolution of 1920x1080 pixels. This means that the display will have a 445 ppi pixel density, which is really high. Currently, the iPhone 5' 4-inch display is 326ppi, and the Samsung Galaxy S III's 4.8-inch display is 306 ppi.
