Today is a pretty big day for owners of three Android smartphones sold by Verizon. That's because the carrier has started rolling out Android 6.0 Marshmallow updates for the HTC One M9, LG G3, and LG G4 - all at the same time.
As always in these cases, it may be a few days before you see the update hit your particular device, as the rollout is staged. That said, if you're impatient you can always manually check by going to the relevant section in Settings.
For the HTC One M9, the new software version is 3.37.605.7, while the LG G3 gets VS98546A and the G4 will run VS98624C. Of course you can expect all of them to pack the latest goodies included by Google in the Android 6.0 release - Now On Tap, the new permissions system, Doze mode (for battery savings), direct sharing, and many more smaller things. The LG G4 is also getting support for Wi-Fi calling.
