Samsung Galaxy S II, the Android-based mobile phone that arrived on shelves only a few days ago with Google's Android 2.3 Gingerbread operating system on board, has just got its dual-core application processor overclocked to 1.5GHz. The dual-core Exynos 4210 Hummingbird CPU was already clocked at 1.2GHz, and the new speed enhancement provided it with a great boost in performance, it seems. Initially, the Samsung Galaxy S II smartphone was unveiled to the world with a 1GHz application processor inside, but Samsung decided to speed it up a little. Thus, after a few weeks' delay, the smartphone was brought to the market with a 1.2Ghz CPU inside, more powerful and more appealing than before. But it seems that the phone has even more to offer, and the guys over at the XDA-Developers forum managed to bring its CPU up to 1.5GHz. The user responsible for this also provided the source code and all the necessary instructions to overclock the device to the new speeds. At 1.5GHz, the Android 2.3 Gingerbread-based phone is stable, they say, and can deliver increased raw power than before, as the screenshots and the video attached to this article show. It scored over 4000 in Quadrant. Although the overclock would make your Galaxy S II fly trough Quadrant and Linpack benchmarking tests, you might want to hold back before trying this at home. The process would require the rooting of the phone which, although it might not be a too risky action, would void the warranty. Those who would be interested in this would be doing it at their own risk. They should head over to this post on the XDA-Developers forum to read the full instructions. Currently, the Samsung Galaxy S II is available for purchase only in a few markets in Asia (South Korea) and Europe (UK, Sweden), but it should be released on in more of them in the near future.
