The Galaxy A series from Samsung has had a pretty good ride in the few months it has been on the market. None of the phones in the lineup have been bestsellers, but their combination of a premium design and mid-range specs has allured quite a few consumers, with the most recent entry – the Galaxy A8 – being the best mid-range smartphone we’ve seen from the Korean giant.

Now, we have learned that Samsung has already started working on sequels to the Galaxy A3, Galaxy A5 and Galaxy A7. We currently know only the model numbers for the smartphones – SM-A310F, SM-A510F, and SM-A710F for Russia, and SM-A5100 and SM-A7100 for China. The model numbers are only small variations on the model numbers of the original trio, suggesting the new devices will not feature drastic changes. A new version of Android will no doubt be one of the attractive features, but we don’t have any concrete information at this point.

It remains to be seen what Samsung will name these new devices in the Galaxy A lineup; going by the model numbers, it’s possible Samsung will simply add something to the existing names. Again, there’s no telling what the company is up to at this point, but we should be able to get a better picture in the future.
