Vietnamese site Tinhte has got its hands on the GT-I9300 -- purportedly the Galaxy S III if Samsung decides to follow its own naming convention. According to the specifications leaked, Tinhte reckons the phone houses a 4.6-inch display at 720 x 1184 resolution (roughly 320 DPI, picking up Android's XHDPI classification), while a quad-core 1.4 GHz processor works on keeping the Ice Cream Sandwich OS running smoothly. Other hardware mentions include 1GB of RAM, 8-megapixel camera, 16GB of storage plus microSD capability. In a side-by-side comparison with the Galaxy Nexus, it looks like the phone's display is incrementally larger.
