Ergonomic Arc Design with Intuitive Rear Controls

When designing the ZenFone 2, we started with you in mind. As a result, ZenFone 2 has a highly-intuitive
control layout, incorporating a physical rear key as part of the new Ergonomic Arc design. Snapping selfies,
adjusting the volume and retracing your steps now feels completely natural, regardless of whether you are
right- or left-handed. The elegant new shape feels secure and extremely comfortable to hold.

Unprecedented Performance
Performance for Today,
and Beyond

ZenFone 2 is powered by a 64-bit 2.3GHz Super Quad-Core Intel® Atom™ Z3580 processor, and is the world’s
first smartphone with 4GB of dual-channel DDR3 RAM. Featuring LTE Cat 4+ for download speeds up to
250Mbit/s, and a 60ms touch response time, ZenFone 2 gives you power beyond your imagination.

Sharp Vision
See What Others Can't See

ZenFone 2’s 13MP PixelMaster camera with its f/2.0-aperture lens captures stunning, high-resolution photos
with zero shutter-lag. The industry-leading Low Light mode employs pixel-merging technology to capture up to
400% brighter photos at night or in low-light scenes, without the need for a flash. Backlight (Super HDR) mode
lets you see clearly through daytime shadow and Super Resolution mode helps you to capture detailed images
at resolutions of up to 52MP!

Tame The Brightness with Backlight (Super HDR) Mode

PixelMaster Backlight (Super HDR) mode automatically captures multiple shots of the scene in the viewfinder,
and processes these using ASUS Pixel Enhancing technology. This expands the dynamic range by 4 times to
give the final picture up to 400% more brightness, along with improved color contrast and detail to ensure the
photos you capture in any scene with strong back-lighting look totally natural.

Unrivaled Low Light Mode

Through a combination of pixel-merging technology, which joins four adjacent pixels to form a new pixel, and
advanced image-processing algorithms, Low Light mode increases light sensitivity by up to 400%. It also enhances noise reduction and boosts color contrast by up to 400%, for clear and bright low-light shots with no need for flash.
