South Korean mobile phone maker Samsung is gearing up for the release of its next-generation flagship Android device, none other than the long rumored Galaxy S III. The smartphone is expected to become official before the end of April, and might arrive on shelves starting next month. In the meantime, the device is undergoing the final touches over at Samsung, and the latest reports on the matter suggest exactly that. According to the guys over at DDaily, Samsung Mobile Display (SMD) has already kicked off production of this screen. They also note that this will be the first non-Pentile phone display coming out from Samsung’s OLED division with an HD resolution. The screen is said to measure 4.65 inches diagonally, the same as the 720p Super AMOLED panel packed on Galaxy Nexus and Galaxy S II HD LTE did. Galaxy S III’s display should feature a pixels density of 316ppi. The Android-powered mobile phone was rumored to be en-route to shelves with a fast quad-core application processor inside, as well as with an 8-megapixel photo snapper on the back (some rumors suggested that the camera would be of 12MP). Apparently, the moment when this device will launch is indeed nearing fast. Samsung reportedly confirmed to AsiaE that it already started testing the mobile phone with wireless carriers in Korea. The handset’s quad-core CPU and LTE capabilities could delay the concluding of testing in the country, although the leading mobile phone maker appears set to complete these procedures before the usual two months term. Galaxy S III is expected to arrive on shelves as the true successor of last year’s popular Galaxy S II, and should deliver great performance capabilities, along with high-end features. The upcoming mobile phone will run under Google’s Android 4.0 Ice Cream Sandwich and will feature Samsung’s TouchWiz on top.
