Android’s monthly security update for November is making its rounds on the AT&T LG G4 and LG V10. The software should be hitting handsets wirelessly as of Wednesday, but may take several days to roll out to all devices.

To check manually if the security update is ready for download users can access Settings > About phone > Check for software. Users should ideally install the software via Wi-Fi with handsets charged to at least 50 percent.
