Designed for people who have a mobile lifestyle, ASUS ZenFone 4 Max (ZC554KL) offers them a battery that should allow them to actively use the smartphone all day long, especially for Internet and gaming. It also comes with dual rear cameras to capture all those memorable moments that occur during the day. While one of the cameras comes with a wide-angle (120 ??) lens, making it more suitable for landscape and group photos, the other one has a large f/2.0 aperture for low-light photography and 13MP resolution. The camera software is engineered to automatically switch between the two cameras on the back of the device.
