No. I'm on t-mobile. My security patch is currently January. The patch would come from the carrier I can't tell you if it's LG or t-mobile that's not releasing the updates. They seem to be in no hurry.
No, LG don't give a bip for user in software update! They say LG commits to monthly Android security updates but it was a big lie! I'm on LG G4 international version H815 unlocked and we are stuck in January with updates. So move to a Nexus or Samsung phone, or Priv. This is my first and last LG phone!
