Ever-connected insider Eldar Murtazin spent some time playing with two unreleased smartphones this weekend. The first was a prototype of Sony Ericsson’s upcoming Anzu, which will reportedly launch as the Xperia X12. The second, perhaps more interesting device was Samsung’s upcoming Galaxy S successor. According to Murtazin, the Galaxy 2 features a dual-core processor and an impressive Super-AMOLED display. He claims it will launch some time in the first quarter of 2011. It is possible that Galaxy 2, known also as the Samsung i9100, could be Samsung’s own version of the Nexus S the company is building for Google — in the same way HTC released the Desire after building Google’s Nexus One. Since no one wants to buy phones directly from Google, we can only hope Samsung spreads out the dual-core Galaxy 2 as well as it did with the Galaxy S, which is currently offered by each of the four major carriers in the U.S.
