While LG has obviously not confirmed any of this, according to recent rumors, the Optimus Vu III will feature a 4:3 display ratio (size of the screen was not mentioned) and will sport a resolution of 1280×960 which would definitely pale in comparison to the Galaxy Note 3 and its rumored 5.7” Full HD display. Other rumored specs remain unknown at this point. The reason behind the speculation that LG could be working on a Vu III is thanks to a photo which was taken by a device known as the LG-F300L, which some have taken to be the Vu III.
In any case take it with a grain of salt for now, but assuming it is true, the Vu III does not appear to be the powerhouse, at least as far as displays are concerned. Perhaps LG might be approaching this from a budget standpoint where it would be an affordable alternative to Samsung’s Galaxy Note 3.
