Verizon is now pushing out an update on the LG G4 running on its network. The 415mb update carries a change log of only security enhancements but with an update this size, it probably has more than just security enhancements. AT&T is also pushing an update currently which includes performance fixes for the keyboard, touch improvement and more.
Check to see if the update is available on your G4 by going into settings-> about phone-> system update.
