Samsung classifies its Galaxy smartphones in three major categories – S goes for the flagship devices, the A is for upper-midrange phones and the J series is where the lower-midrangers hang out.
According to the US Patent and Trademark Office, the third family is about to get bigger – the Korean company trademarked the monikers Galaxy J3 Star and Galaxy J7 Star.
The “Star” addition will join other sub-series like Pro, Prime, Max, Ace, and Nxt. Both phones are yet to be announced, but since stars are usually seen in the sky, we should expect the J3 Star and J7 Star to sit a bit higher than their vanilla J-series counterparts.[“Source-timesofindia”]
