Based on another thread, it seems the straight LG 4 cell phone works with the Mini2/Fly combo, but the LG 4 no longer appears to be available.   I do however see what is labeled in some places as an LG 4 Journey.   Given how Fly works with some phones and not others, you cannot take for granted that even similar phones will work, so I am asking if there is a known compatibility or incompatibility between Fly and the LG Journey cell phone based on actual experience.   The same question for the LG K31 Rebel
