Back at MWC 2011, Samsung announced the highly anticipated successor to the Galaxy S the Galaxy S II. At that time, the Galaxy S II was supposed to feature a 1GHz dual-core Exynos processor.
However, a month down the line Samsung decided to bump the clock speed of the processor to 1.2GHz. The already fast Galaxy S II got faster, due to the 200MHz speed bump on each core.
The Galaxy S II is already the fastest Android smartphone ever. However, this has not stopped the awesome developer coolbho3000 to overclock his Galaxy S II to 1.5GHz, in a bid to make it faster! Yes, that’s 1.5GHz (1504MHz to be precise)!
He has uploaded a video of his Galaxy S II running at 1.5GHz and ripping through all the benchmarks. Here is the video of the Galaxy S II overclocked to 1.5GHz :
He has also posted the steps so that fellow Galaxy S II owners can overclock their phone to 1.5GHz, if they wish to. Here is the link to the thread over at the XDA forums.
I will recommend general Galaxy S II owners to stay away from installing this kernel on their handset, except for testing needs.
