According to a Korean web site called MovePlayer, Samsung is working on a smartphone that is equipped with as display offering resolution of 768 x 1280 (WXGA)
. The handset is known only by its model number, which is SHV-120S. Not much is known about this phone except that it will run Android 2.3 and have a Qualcomm MSM8250 single-core 1GHz processor under the hood. The display handles 16 million colors. The information was discovered in a registration made to SK Telecom's T Store Developer Center. If Samsung uses this display on a 4.5 inch screen, the pixels per inch would come in at 332, topping the 326ppi reading of the Retina Display on the Apple iPhone 4.
One possibility is that the model is the Nexus Prime which would use the Ice Cream Sandwich build of the Android OS. That build does away with hardware buttons on the front of the phone, allowing for a larger sized screen. As we hear more about the SHV-120S, we will pass it on to you. After all, a display offering such high resolution will be easy to keep an eye on.
