Asus has started seeding the Android 6.0 Marshmallow update to Zenfone Max and Zenfone 2 users. The models receiving the updates are the ZenFone 2 Laser 5-inch (model number ZE500KL), ZenFone 2 Laser 5.5-inch (model number ZE550KL), and ZenFone Max (model number ZC550KL).
The update brings an array of new features like Google Now on Tap, Doze mode and app permissions. Apart from that, Asus suggests that the pre-installed Asus Email, Asus Calendar, and Asus Messaging post the update will not be working. So, all Zenfone users should use their Gmail, Google Calendar, and Google Messenger instead.
The company which made the update announcement on a user forum thread says the update will not be supporting APP2SD functionality anymore. This means users can no longer store apps on the SD cards. Users are advised to move apps to internal storage from their SD card before the system upgrades to Android Marshmallow.
The latest update is an over-the-air one, so it should pop up as a notification on the Zenfone devices. To check manually for the update, head over to Settings> About device>Software update and see if any update message reflects. You will just have to be patient until the update is seeded to your device.
Asus recently released three new models of the Zenfone called Asus Zenfone 3, Zenfone 3 Deluxe and Zenfone 3 Ultra at the Computex 2016. All of these models come pre-installed with Android's 6.0.1 Marshmallow OS version.
