Last year, we exclusively reported about the existence of Galaxy A, Galaxy E, and Galaxy J series of smartphones from Samsung. Now, we have information regarding an new series of smartphones from the South Korean smartphone giant.

According to the exclusive information that we’ve received recently, the company is currently working on two new smartphones, the SM-G550 and the SM-G600, and they’ll be released under the Galaxy O series. The SM-G550 will most probably be named Galaxy O5, while the SM-G600 will be named Galaxy O7. Currently, we don’t have any further information about these devices, be it regarding their specifications or the time frame of their possible announcement.

Starting late 2014, Samsung started improving their smartphone nomenclature by grouping all its new launches under new series named after alphabets. We hoped that Samsung would tidy up its smartphone lineup and control the number of smartphones that it releases each year, but it doesn’t appear to be so. After the announcement of the Galaxy O series, Samsung would have 6 series of smartphones, Galaxy J, Galaxy E, Galaxy A, Galaxy O, Galaxy S, and Galaxy Note, which is still too much for consumers to handle.

Let’s hope that the Galaxy O series comes with a new design as it would be easier for consumers to remember and differentiate them from other smartphones made by Samsung.

Update: Looks like the Galaxy Mega and the Galaxy Grand series of smartphones aren’t dead after all.

Today, we’ve came across two new smartphones from Samsung, the Galaxy Mega On and the Galaxy Grand On, and they have the same model numbers that we reported as Galaxy O series earlier this week. Looks like Samsung has decided to name the SM-G600 as Galaxy Mega On, while the SM-G550 has been named the Galaxy Grand On.

We know that we reported these smartphones as Galaxy O series, but this happens when come across devices that are at very early stages of development. Things change internally and brands decide to rename things, similar to what happened with Project Orbis. The smartwatch was renamed from Gear A to Gear S2, and was teased last week after the announcement of the Galaxy Note 5 and the Galaxy S6 edge+.
