After releasing the Android Marshmallow to HTC One M8, the company is prepping to roll out the update to One M9 in US later this month.
HTC USA chief, Mo Versi (on Twitter) confirmed that the flagship HTC One (M9) will get to taste Google's new sugar treat flavoured mobile update by December end.
He also added that the newly launched HTC One A9, which came with Android Marshmallow out-of-the-box, will receive the latest stability update v6.0.1 in a few days time.
Key aspect of Google's new Android Marshmallow OS is the Doze power-saving feature. If the device is in sleep mode, it will automatically put apps to sleep to increase the device's standby battery life. It can extend battery life by at least 30% depending on the device's internal hardware.
Other noteworthy features include native support for fingerprint sensor input, a leaner and faster Chrome browser, more intuitive Now on Tap feature, new security-feature-verified boot system, support for more international dialects, new contextual assistance feature, Google photos and auto back-up from where all apps user data (less than 25MB) will automatically be stored in Google Drive.
Lots of questions on this, so quick update: M9 unlocked Marshmallow OS update and A9 6.0.1 (with updated emoji) is on target for this month.— Mo Versi (@moversi) December 7, 2015
Meanwhile, v6.0.1 Marshmallow will bring security patches, bug-fixes, close to 200 new Unicode 8 Emojis. It also brings back the 'until next time' option to Do Not Disturb feature, which was first introduced in Android's v5.1 but was dropped in Android v6.0.
Other HTC devices slated to get the new Android Marshmallow include One M9+, E9+, E9, ME, E8, One M8 Eye, Butterfly 3, Desire 826, Desire 820 and Desire 816.
