ZenFone 4 is a 5.5-inch smartphone that evolves the ZenFone lineage with luxurious, crafted design and delivers an unparalleled mobile photography experience with a dual-lens camera system featuring the flagship Sony IMX362 image sensor, a large F1.8 aperture lens and a 120° wide-angle lens. The powerful and energy-efficient Qualcomm Snapdragon mobile platform provides performance for every scenario and a high-capacity lithium polymer battery coupled with ASUS BoostMaster fast-charging technology keeps ZenFone 4 going longer.
ZenFone 4 features an advanced dual-camera system that expands your creative options to take your mobile photography to new heights. Its 12MP main camera is equipped with the industry-leading Sony IMX362 image sensor with large 1.4µm pixels and a wide, F1.8 aperture lens to capture up to 5x brighter and clearer photos in low light. Its 120° wide-angle camera provides a 200% larger view than standard traditional smartphone cameras, letting you fit more scenery and people in the frame for dramatic landscape shots, better group photos, and a more convenient photography experience in confined indoor spaces. With instant switching between cameras, you can quickly achieve the perfect composition for your photo without missing the moment you want to capture. Camera performance is further improved by the Qualcomm Spectra 160 image signal processor (ISP), which ensures faster, smoother focusing and zooming, as well as photos with better color accuracy.
Fit more scenery and friends in the shot
The 120° wide-angle camera on ZenFone 4 has a 200% larger field of view than standard smartphone cameras, so you can fit more scenery and people in the frame for dramatic photos and videos that capture a true sense of place. When taking photos indoors, the wide-angle view makes it much easier to get the shot you want - especially in confined spaces where it may not be possible to take a few steps back to fit everyone and everything into the photo. The unique perspective of the wide-angle lens can also be used to stylistic effect, allowing you to exaggerate the sense of space in any setting to capture more dramatic scenes and stunning, expansive landscapes.
Capture reality, fast and steady
A dual pixel camera unit with 24 million focus detection sensors - two for each of its pixels - provides ultrafast 0.03 seconds phase-detection and subject-tracking auto-focus to ensure sharp and clear photos. Together with both optical and electronic image stabilization for blur-free photos and videos, a color correction sensor for true-to-life colors, and true 4K UHD video recording, the camera on ZenFone 4 goes above and beyond other smartphones.
Efficiently powerful, effortlessly fast
ZenFone 4 combines incredible performance, optimized power efficiency, and advanced connectivity with security and convenience features to deliver a mobile experience like no other. The Qualcomm Snapdragon mobile platform offers dramatically faster CPU and GPU performance for all of your apps and games. ZenFone 4 supports Category 12/13 4G LTE Advanced technology and 802.11ac dual-band Wi-Fi with MIMO for blazingly fast network connectivity in any situation. Built-in NFC enables convenient mobile payments with Android Pay, and a front-mounted fingerprint reader offers improved security and faster phone unlocking.
Charge faster, work and play longer
When creating ZenFone 4, ASUS engineers combined the fantastic energy-efficiency of the Qualcomm Snapdragon 660 and Snapdragon 630 mobile platforms with a high-capacity lithium polymer battery, resulting in a smartphone that delivers up to 23 days of 4G standby time. When it's time to recharge, ASUS BoostMaster technology provides 15W of power for incredibly fast charging. With ZenFone 4's supplied adapter, just a five-minute charge provides two hours of talk time or achieves a 50% charge in just 36 minutes and built-in safeguards protect against overcharging.
Bright and smart-adaptive display
With a bright 600-nit Super IPS+ display, ZenFone 4 makes photos, videos, and all your other content look as vibrant as real life, even when viewed outdoors in bright sunlight. ASUS Splendid technology lets users adjust the color temperature of the display based on environmental lighting for the most comfortable viewing experience.
Expansive stereo sound
ZenFone 4 is built with dual speakers and multiple audio technologies to provide the best sound for entertainment and phone calls. Its stereo speakers deliver expansive, low-distortion sounds, even at high volumes. Two noise-canceling microphones remove unwanted environmental sounds for the best call quality and clear sound when recording videos or live streaming. Hi-Res Audio certification enables 24-bit/192kHz - 4x CD quality - audio playback. DTS Headphone: X provides theater-quality 7.1-channel virtual surround sound over headphones.
