Verizon has started rolling out the Android 6.0 Marshmallow update for a slew of handsets in the U.S.

The flagships LG G3, LG G4 and the HTC One M9 are apparently receiving the Marshmallow firmware. Within a couple of days, all the aforesaid device owners under Verizon should receive the notification regarding the software package as it’s being sent in phases.

As a prerequisite for download and installation, the device should be at least half-charged and it’s preferable to have a stable Wi-Fi connection. In case, owners of LG G3, LG G4 and HTC One M9 would not like to wait for the update to come knocking the door, manual upgradation is also possible.

In order to manually update the handsets to Android 6.0 Marshmallow, navigate to Settings on the LG G3 or LG G4 -> go to About Phone -> Update Center -> System Updates -> Check for Update. In the case of HTC One M9, navigate to Settings -> System Updates -> HTC software update -> Check Now.

Other eligible LG handsets earmarked to receive the Marshmallow update at some point this year include the LG V10 and LG G Flex 2. As of today, there’s no information available to ascertain the eligibility of the LG G2. However, not long ago, this device made a visit to the Geekbench site with Marshmallow on board.

T-Mobile, on the other hand, is expected to send out the Android 6.0 marshmallow update to the HTC One M9 owners shortly. The carrier has already started rolling out the latest firmware update to the LG G4. The LG G3 is eligible to get the update. However, at this point, there’s no official confirmation available on the roll out date.

Speaking of HTC One M8, towards the end of January, Sprint version of the handset and Harman Kardon edition started receiving the Android 6.0 Marshmallow update. Sprint’s HTC One A9 has also received the firmware update.
