The Nougat update for the LG G4 smartphone is now available. Currently, the availability is only limited to the company's home country of South Korea. Also, the update is only accessible through the LG Bridge app. KDZ images of the update are also available to download from XDA Developers. However, those are currently only available for F500S, F500L, or F500K models. You can use these images to carry out manual installation of the update. There's currently no information on when the OTA roll out will begin, but that should not take long (if it hasn't already started). Via | XDA
