Asus ZenFone 4 Midnight Black 64GB Unlocked GSM Phone - ZE554KL-S630-4G64G-BK


  • Dual Cameras - 5x Light Sensitivity & 120° Wide View
    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 latest powerful and energy-efficient Qualcomm® Snapdragon™ 660/630 Mobile Platform provides performance for every scenario and a high-capacity 3300mAh lithium polymer battery coupled with ASUS BoostMaster fast-charging technology keeps ZenFone 4 going longer
  • Dual Rear Cameras. See a bigger and brighter world
    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
  • Wide-Angle Camera. 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. * Calculation based on a standard lens with an 83° (25mm) field of view and a wide-angle lens with a 120° (12mm) field of view
  • High Light Sensitivity. 5x brighter and clearer photos in low light
    To capture real-world authenticity, ZenFone 4 packs a 12MP main camera with a wide F1.8 aperture, plus the latest Sony® IMX362 sensor with a large 1.4µm pixel size. Combined with optical image stabilization (OIS) that allows blur-free handheld exposures of up to 1/4 seconds — 3x longer than cameras without OIS — and a six-element lens, 5x* more light can reach the camera sensor, making ZenFone 4 perfect for capturing brighter, clearer true-to-life photos at night, in low-light environments, and in back-lit situations
  • PixelMaster Technology. 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
  • PixelMaster Camera Modes. Shoot like a pro, capture the fun
    The optional Pro mode offers manual camera controls similar to those found on DSLRs to give you complete creative control over your photography. With one-touch adjustments to shutter speed, white balance, exposure and ISO, as well as the ability to make your subjects stand out with Portrait mode and shoot in RAW format, ZenFone 4's extensive camera controls let you capture stunning images that truly express your photographic vision. In addition to its advanced, manual controls, ZenFone 4's camera has an assortment of fun, creative modes to enhance your photography experience and let you easily achieve professional-looking results
  • SelfieMaster. More beautiful, more fun, more you
    ASUS SelfieMaster is a fun and intuitive app that lets you apply beautification effects to make your selfies even more glamourous. With ten levels of beautification to choose from, you can smooth wrinkles, remove blemishes, adjust skin tone, and enhance your features instantly. Whether you are taking photos, capturing a video, or live streaming, SelfieMaster lets you create your perfect look for the camera. You can even use its smart photo editing features to create collages and slideshows to enjoy and share with friends
  • 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 latest Qualcomm® Snapdragon™ 660/630 Mobile Platform with up to 6GB of RAM 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 3300mAh 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
  • Evolved Zen Craftsmanship. Evolved beauty and tactility
    ZenFone 4 evolves the prestigious ZenFone design lineage with numerous refinements that give it a singular beauty and provide an unparalleled user experience. Crafted with a solid aluminum unibody using advanced Nano Molding Technology (NMT), ZenFone 4 is thin and light, yet incredibly strong. An expansive 5.5-inch display is surrounded by an ultra-narrow bezel, providing a cinematic view and a slimmer width for easy one-handed operation. ZenFone 4's dual camera system is integrated completely within the phone chassis for a perfectly flat rear surface with no protrusions. Both the front and rear of the ZenFone 4 are encased in 2.5D curved Corning® Gorilla® Glass that provides a more comfortable grip and a durable, scratch-resistant finish. A fine, diamond-cut metal edge provides a luxurious accent and micro-etched, concentric-circle detailing that catches the light to make ZenFone 4 shimmer with a rich luster
  • Super IPS+ Display. 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. The all-new AudioWizard app lets you tailor audio output to your preference, and DTS Headphone:X™ provides theater-quality 7.1-channel virtual surround sound over headphones
  • ZenUI 4.0. Simpler. Faster. Smarter.
    Simpler, faster and even smarter than ever, ASUS ZenUI 4.0 features a new visual design and keeps only the essential apps. It works faster thanks to quicker response across the board too.
