Samsung is apparently gearing up to release a new series of devices, dubbed “Galaxy O.” The Galaxy O will be joining the illustrious list of the Galaxy S, Galaxy J, Galaxy E, Galaxy A, Galaxy Z and Galaxy K lineup of smartphones. The South Korea technology giant is reportedly working on two new devices namely the Galaxy O5 and Galaxy O7.

The Samsung Galaxy O5 and Galaxy O7 are reportedly referred internally as "SM-G550" and "SM-G600," respectively. Going by the device names, it’s clear that Samsung’s upcoming smartphones do not follow the linear alphabetical order of naming convention. For instance, the flagships use the moniker Galaxy S series, while the Galaxy J series is considered to be the entry-level devices, GSM Arena reported. The Galaxy A series represents the alternative to the expensive Galaxy S range, and it boasts metal body.

The Galaxy E series are considered as relatively more affordable variants of the metal-clad Galaxy A lineup. Meanwhile, the Galaxy Z series runs on the company’s own Tizen OS, as opposed to Google’s Android mobile operating system. The Galaxy K series comes with a bulky, protruding primary camera and marketed as a camera-focused handset. To top it all off, Samsung apparently has Galaxy V series and a Galaxy W tablet as well.

In addition to the alphabetical monikers, Samsung also has Galaxy Note, Galaxy Xcover, Galaxy Pocket, Galaxy Grand, Galaxy Aces, Galaxy Star, Galaxy Young and Galaxy Core lineup of devices as well. This clearly shows that Samsung does not follow a linear order or pattern when it comes to naming its devices. With the available information, the Galaxy O series cannot be fitted into high, mid or low-end category. According to GSM Arena, there is a good chance that the Galaxy O5 and Galaxy O7 might be introduced at the upcoming IFA 2015 event in September.
