Is there another version of the note 4 coming to the US. Read and article saying that SD 810 would be in the Note 4. And it was official from Samsung. Anyone hear that?
It's not official, it's just a rumor. And Samsung has been very open about their issues with the 810 (overheating), so it's unlikely that they'll use it on the S6, let alone a 'new' Note 4.

The Exynos-powered model, however, is in theory 64-bit ready but it's only running in 32-bit mode, and Samsung has said that it plans to stay that way even with the Lollipop update, at least for now.
