Sprint is the first American carrier to get Android 6.0 Marshmallow started for the LG G4. The rollout has commenced, and users are starting to get the goods over-the-air, or so says this handy support page.
Sprint didn’t go into great detail about the update in their changelog, but you should already know it brings some of the exciting new Marshmallow features such as granular permission control, Google Now on Tap, Doze Mode for saving battery life and more. Sprint also says this update will enable the company’s global roaming feature.
You’re looking for version LS991ZV9, so charge your battery up, hop onto WiFi and check for it at your earliest convenience. Don’t be too confused if you can’t pull it down right away as Sprint is likely to push out such a big update in waves.
