HTC has kept Their promise and managed to end the year with the release of an update for its flagship smartphone. The Htc One M9 is now officially upgradeable to the new operating system Android 6.0 Marshmallow. It should be noted that the update will takes place in two stages. You must first download a file "size" of 99.47 MB which will help to be prepare the phone for the new update, and then download the main firmware file which will takes up to 1.21 GB of free space on your smartphone.
Users of the HTC One M9 can expect the following Marshmallow features: Now on Tap which will allow you to access contextual information from any app without having to leave said app; Doze to extend your battery life when your device is just idle; a brand new permissions system; and your microSD card can be converted into internal storage (but with caveats of course).
As for the other devices still waiting for their Marshmallow, you might have to be content with roasting actual marshmallows by your fireplace this Christmas as we’re still waiting for other official announcements from other OEMs and carriers.
