While we’ve no idea if these names will ever be used to designate real devices, there is a certain logic behind them. LG currently has a G series of smartphones (including the latest G3), an F series (including the F90 and F70), and an L series (L90, L70, etc). What about the W, then? Well, this one may be reserved for a brand new Windows Phone 8.1 handset.
Of course, it’s hard to imagine that in the near future LG could, for example, launch a G Prime that’s more advanced than the G3 already is. But, in the long run, this could definitely happen. We’ll keep an eye on this, and let you know when more details are available.
