The Galaxy J series is about to expand with the addition of a few new smartphones. The unannounced Galaxy J7 (2017) is one of the handsets Samsung is expected to reveal very soon, but that might not be the only affordable smartphone launched by the South Korean company in Q1.

We reported less than a week ago about the Galaxy J7 Sky Pro, a name that Samsung trademarked in late January. Even though we don't have a confirmation yet, this might be a carrier-branded version of the long-rumored Galaxy J7 (2017), which will be released in the United States.

The name of a third Galaxy J series device has been spotted recently at USPTO (United States Patent and Trademark Office): Galaxy J3 Luna Pro. Judging by its name, this doesn't seem to be another variant of the Galaxy J7 (2017), but rather a refresh of the last yearGalaxy J3 Pro.

Although it might not mean anything, it looks like Samsung trademarked both the Galaxy J7 Sky Pro and Galaxy J3 Luna Pro names on the same day, January 24, 2017. The next step for Samsung would be to make both affordable smartphones official.
