Marshmallow was released last fall, in October and now it runs on 10 percent of all active Android devices. Some of the Asus devices launched in 2015 that were upgraded to the latest 6.0 Marshmallow are Zenfone 2 Laser ZE500KL and Zenfone Max ZC550KL and now two more smartphones are catching up: Zenfone 2 ZE551ML and ZE550ML.
The two aforementioned devices will get the Android 6.0 Marshmallow update over-the-air and the installation file will weigh 1.1GB, which means that users will need to connect to a WiFi network in order to download it. The update brings many new features (Google Now on Tap, Doze mode, app permissions), improvements, bug fixes, but Asus has also removed a god deal of bloatware. If users can’t wait until they will receive the update notification, they will manually install the update by follow the Source link for download links and instructions.
