  • 1Description

Elevate your mobile photography to all new heights with the pure black ZenFone 4 Pro Smartphone from ASUS. This dynamic smartphone features a powerful rear camera array that includes a pair of pro-level shooters capable of capturing the world in lifelike detail. The first lens is a Sony IMX362 12MP dual-pixel sensor with a f/1.7 aperture; the second a Sony IMX351 16MP image sensor with up to 10x total zoom. On the front of the phone is an 8MP Sony IMX319 sensor powered by ASUS's SuperPixel Engine. Several PixelMaster camera modes are available with this advanced setup, including Super Resolution, Beauty mode, and many more.

On top of its sophisticated camera capabilities, the ZenFone 4 Pro is also powerful communication and multimedia device. It's equipped with a Snapdragon 835 processor with 6GB of built-in RAM in support. For storage purposes, the ZenFone 4 Pro includes 64GB of base memory and features a microSD slot that supports cards up to 2TB. The ZenFone 4 Pro houses a 5.5" AMOLED display with 1920 x 1080 resolution, which will deliver robust images and color depth, and supports smooth, responsive interaction with the touchscreen and UI.

The ZenFone 4 Pro is also well-equipped for wireless communication. It features Bluetooth technology for pairing with other Bluetooth-enabled devices, and 802.11 a/b/g/n/ac Wi-Fi for high-speed Internet connectivity. GPS with GLONASS is on-board for using location-based apps and services. In terms of power, the ZenFone 4 Pro features a 3600mAh non-removable battery that delivers hours of enjoyment, including up to 27.5 hours of 3G talk time, 17 hours of Wi-Fi web browsing, and 21 hours of 720p video playback. And if you need a quick boost, the ZenFone 4 Pro gets up to 2 hours of talk time off only 5 minutes of charging.

GSM / 4G LTE Wireless Connectivity
This phone is designed to work on select GSM networks and is 4G LTE capable. LTE is an advanced cellular network data protocol capable of data speeds so fast that they compete with wired broadband Internet providers. With an LTE connection, this phone should have no problem streaming HD video, downloading apps, uploading photos, or anything else that requires a high-speed data connection. The phone is also backwards compatible with 3G and 2G data for instances when you can't get LTE. In addition to cellular wireless, this phone also features Bluetooth and Wi-Fi connectivity.

Note: Not compatible with all cellular networks. Please make sure your provider uses a frequency or band that this phone supports. You can check which bands this phone works with in the Specifications.

It can also be used in other parts of the world; however, LTE access may be limited or unsupported, depending on the network. To ensure this phone will work with your carrier please check to make sure the frequencies your carrier uses are supported by this phone. The full list of compatible carrier frequencies can be found here, the frequencies this phone supports can be found in the product specs.
Dual Rear Cameras
ASUS ZenFone 4 Pro is capable of capturing real-world authenticity thanks to its powerful rear dual camera array. This advanced setup includes two Sony flagship sensors that will deliver true-to-life pictures no matter the environment.
See a Bigger, Brighter World
ZenFone 4 Pro's Sony IMX362 image sensor can capture up to 8x brighter and clearer photos in low light (compared to a "typical" smartphone camera with 16MP resolution). When you need to get closer, switch instantly to the 16MP camera with a 2x optical zoom and 10x total zoom to shoot highly detailed telephoto pictures. Both camera lenses are covered with durable sapphire glass to protect against scratches. Qualcomm Spectra image signal processing improves your photography experience even further, providing smoother zooming, faster auto-focus, and photos with gorgeous, true-to-life colors.
Shoot Like A Pro
With ZenFone 4 Pro, you get optional manual controls similar to those found on DSLRs, giving you pro-level creative control over your photography. Pro mode provides complete camera control with one-touch adjustments to shutter speed, white balance, exposure, and ISO settings, as well as the option to shoot in RAW format. In addition to its manual controls, ZenFone 4 Pro's camera has an assortment of fun, creative modes to enhance your photography experience and let you easily achieve professional-looking results.
Beautiful Selfies, Day or Night
In addition to its powerful dual rear camera setup, the ZenFone 4 Pro is also an advanced selfie shooter. Its front-facing camera features fast, phase-detection auto-focus, a Sony IMX319 image sensor with f/1.9 aperture, and 1.4Ám pixel size. All of this is supported by ASUS's SuperPixel Engine that boosts light sensitivity while reducing image noise, letting you capture clear and vivid selfies, day or night, indoors or outside.
Android 7.1 Nougat
The Android operating system integrates heavily with Google's services. Using the card-based Google Now, Android quickly surfaces information for you whenever you need it, powered by the same Knowledge Engine that runs Google's web search. It's a personalized and customizable OS, allowing you to add your favorite apps or widgets to your homescreen. You can even download new themes using the Google Play Store, which offers access to more than one million apps, games, books, music, movies, and more. Android 7.1 Nougat adds major productivity capabilities to the operating system in the form of a multi-window view, which allows for two apps to be placed onscreen at a time. An improved notification system allows you to interact with texts and emails right from your notification pane - without needing to open the app. Other features include file-based encryption, a Data Saver mode, the ability to scale text and icons to better suit your phone's screen, and more.
Dual SIM Dual Standby (DSDS)
Dual SIM Dual Standby (DSDS) allows you to lower your mobile costs when traveling while staying connected. Once your SIM cards are installed, you will be able to receive phone calls and text messages from either without needing to manually choose which one is active. When you want to make a call or send an SMS message, you can select the correct SIM card. When one SIM card is being used for a phone call, the other will not be active until you hang up. Operator charges may apply.
