Not working on a “Nexus 5″ doesn’t mean, they are not working on a new “Nexus 4″ – please begin to understand, that the number doesn’t count the revisions but resembles the display size (Asus also isn’t working on a Nexus 8).
What the press man said, doesn’t rule out a new “Nexus 4″ from LG.
Don’t let LG press departement fool you…
