The poor, neglected Galaxy S series of phones may have earned Samsung a reputation for being slow to update their devices, especially here in the states. Today, however, a build of Ice Cream Sandwich for the Epic 4G Touch was leaked that suggests Samsung is making decent progress on the ICS front. So, while Sammy may be a touch on the slow side, at last they're working on it! That's something, right?

QBKing77 has put together a 16-minute walkthrough video of the build demonstrating all the major ICS features running on an E4GT including continuous voice-transcription, face-unlock, the new multitasking carousel, and swipe-to-dismiss notifications and apps. We also see that the multitasking carousel appears by long-pressing the Home key, so don't panic about the lack of on-screen buttons.

The build, however, is still not quite ready for prime time. For starters, the big feature that everyone loves most about ICS—its facelift—hasn't been touched at all. Some parts of the UI aren't finished. For example, the network icon changes between two different style icons. Some settings use the ICS-style buttons, while others look exactly like TouchWiz on Gingerbread. It's very likely that Samsung is still working on UI improvements.

If that wasn't enough to convince you this isn't final, the build number here is "FB09 test-keys." Clearly this isn't something Samsung is ready to drop on the public any time soon. It's encouraging, however, that Samsung is not only working on updates for the SGSII line of phones, but also for the typically-neglected US variants. Now if only it can keep the rest of its devices up to date, we'll be golden.
