Samsung is preparing such a smartphone, the one I have seen Motorola and HTC Vigor no longer needs no introduction. We’re talking about 720p screen terminals, as is the case of Sony Ericsson Nozomi, codenamed LT26i/LT26a. The phone will have a rate of DPI (dots per inch) 341, so higher than that of Retina Display on iPhone 4.
To achieve this performance, Nozomi uses a 4.3-inch screen with 1280 x 720 pixels. Rumors say that its facilities will include a single core processor 1.4 GHz Snapdragon chipset and graphics adreno 205.
