HTC’s Sense UI might have been garnering a lot of criticism over the last one year due to its bloated feel, and sluggish performance even on dual-core handsets.
This, however, does not deny the fact that Sense UI looks absoutely stunning. Many developers try to port the SEnse UI to their non-HTC phone, but nearly all of them fail miserably. The difference in hardware and proprietary files of Sense UI being the biggest hurdle on their road to success.
However, one developer – QuBe2 – over at XDA forums has managed to port HTC One X based Sense 4.0 ROM to the Nexus S. The ROM does have some issues including Wi-Fi not working for quite a few people, random reboots, and Bluetooth being a no-go but the developer is working hard on fixing these issues.
Keep in mind that since the Nexus S has a single core processor and only half the amount of RAM as the One X, there might be some performance issues. Sense after all is known for all its bloat. Head over to this thread on XDA forums for the download link and installation instructions. The list of what works and what does not work can be found here.
