The ZenFone 5Z's smart cameras take all of the work out of enhancing your photos. The smart technology utilizes dual 12MP/8MP rear cameras and an 8MP front-facing camera. When snapping a photo, the 5Z analyzes the subject, detects what is, and adjusts the settings. When you take a portrait with either side, it intelligently gives you a close-up with a graduated bokeh effect for pro-level results. It even beautifies faces automatically, regardless of age, shape, skin tone, or gender.

Running the Android 8.0 Oreo operating system, this phone is powered by a 2.7/1.7 GHz Octa-Core processor (4 x 2.7 GHz Kryo 385 Gold, 4 x 1.4 GHz Kryo 385 Silver) and 6GB of RAM. You can store your apps, professional portraits, and enhanced images on 64GB of built-in storage, which can be expanded via an (optional) microSD card up to 2TB in size. Note that utilizing a microSD card will use the second SIM slot.

This phone is unlocked and compatible with GSM/4G LTE networks. If you travel a lot or have a separate work number, you can take advantage of the Dual SIM slots to access both accounts. Connect to the internet and other devices with built-in 802.11 a/b/g/n/ac 2.4+5 GHz dual-band Wi-Fi, Bluetooth 5.0, and Wi-Fi Direct. The ZenFone 5Z also supports NFC technology for making phone-to-phone data transfers or mobile payments.

Android 8.0 Oreo

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 home screen. You can even download new themes using the Google Play Store, which offers access to millions of apps, games, books, music, movies, and more. Android 8.0 Oreo adds major productivity and security capabilities to the operating system. They've introduced Google Play Protect, which scans apps on your phone to detect harmful behavior. With the touch of the Home button, continue to work in apps while watching active videos in Picture-in-Picture mode. Other features include, faster boot speed, automatically turning on Wi-Fi when near saved networks, limiting background activity for little used apps, notification snoozing, smart text selection, and more.

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.

North American Variant / US Compatible LTE

The ZS620KL is a US variant of the ZenFone 5Z. The ZS620KL's LTE radio is tuned to frequencies that are most often used in the United States and North America. 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 Standby SIM (DSS)

Dual Standby SIM (DSS) allows you to lower your mobile costs when traveling while staying connected. With dual SIM card slots users have the freedom and convenience to access two different phone numbers. Additionally, the dual SIM card slots allow you to have two carrier options, such as having an international number and a national number. With Dual Standby SIM (DSS) users have to manually switch which SIM is active, when one SIM card is selected the other will not be able to make or receive phone calls or texts.

AI Scene Detection

Snap a photo and the 5Z will analyze your subject and match it to one of 16 scene types, figuring out what exactly it is. Is it the sky, a slice of pizza, or your dog? This technology is designed to figure it out and then optimize the camera settings to match, helping give you more perfect photos automatically. The 16 scene types include: People, Food, Dog, Cat, Sunset, Sky, Green Field, Ocean, Flower, Plant, Snow, Night View, Stage, Text, QR Code, and Tripod.

AI Photo Learning

When you tweak the settings of your images, the ZenFone 5Z will learn the types of settings you like on particular picture types. As it learns, it will start to recognize repeated image types and automatically make those changes for you.

Real-Time Beautification

When the phone detects that you're shooting a face, it will analyze over 2 million previous enhancements from 365 facial points, automatically making enhancements to produce a more natural and professional result.

AI Gallery

The 5Z intelligently organizes your photos based on type (Foot, Flower, Dog, etc..) or even by people's names through facial recognition. This is designed to make it easier to find the photos you are looking for in order to share them with others.

Strong Design

The body of the 5Z is constructed from special aerospace-grade aluminum and is covered by glass. This is meant to keep the phone light and strong. It's finished using zircon-sandblasting technology and an 8-layer optical coating process. A final varnish coat under the glass helps to give it a deep, rich luster.

The entire construction consists of a complex, 206-step process that includes little details, such as a TPU layer under the metal buttons for a more reliable and positive feel, as well as an anti-glare coating to help reduce reflections, improve image quality, and help hide the cameras from view.

AI Call Technology

In order to product clearer phone calls, built-in AI technology intelligently provides ambient noise cancelation in noisy environments. It will also boost quiet calls so they can be more easily heard.

Intelligent Apps

The ZenFone 5Z actively learns your favorite apps and is designed to intelligently predict the apps you'll most likely use next. It does this in order to make sure the apps launch quicker, and that app switching is seamless.

ASUS BoostMaster

BoostMaster is AI-powered charging, which is designed to dynamically adjust the charging rate, slowing down the 3300mAh battery's aging process.

Smart and Powerful Audio

Built-in stereo speakers are driven by a powerful NXP low-distortion dual Smart AMP, which is designed to provide deep, rich, and expansive sound. The dual Smart AMP intelligently monitors the speakers' performance to drive them louder if needed, while protecting them from damage. Overall, the speakers are 36% bigger than the ZenFone 4, with a 46% louder bottom speaker, and a 27% louder top speaker.

ASUS AudioWizard

Built-in profiles for different music types let you tailor the phone's settings to suit your listening tastes. The built-in profiles include Jazz, Rock, Pop, Dance, Classic, Vocal, and Normal.

ASUS 5Z Reviews

So far my thoughts!

When i first got the phone, I noticed battery drain issue. It would last only half of the day. Even drain battery while being on a Samsung fast charger. Rest of the things were better than expected. Also there were many software updates. Phone came with Android 8 then updated 9 then to 10. On Android 8, Asus had many useless apps loaded and had cartoonish user interface but after updating to 10 it become more like pure Android and most of Asus sideloaded apps went away automatically. That recent May 2020 update for Android 10 is a must, before that phone became laggy on Android 10. After all updates i really like the phone, very fast and user friendly so, i didn't want to return it despite of battery drain issue. So, i researched a lot and tried a lot of things even downgraded to Android 9 to see if Android 10 is the issue. That battery issue finally resolved. How that battery issue got resolved? First, I found out that Samsung fast chargers are not compatible for some reason. Included charger or any other charger works just fine. I am using my old Motorola charger and its been great. Second, Google Photos was eating up a ton of battery. Which Google just updated and that got fixed up. Third, I think drain battery all the way to zero helped too after updating to latest update of Android 10. Now I happy about every single thing about this phone. There are little things that you would appreciate about this device. For example face recognition, build in call recorder, good and fast camera for photos and more.

Having used a Samsung S4 to its death this phone is a remarkable upgrade. Set- up was easy even for a tech challenged person like me. The display is fabulous, battery life is exceptional and the processor speed is lightning. With 6gb of RAM and with 44+ apps running I am only using 57% capacity. Apps that were a pain before, run seamlessly now. The camera seems to be pretty good and more than adequate for my use. Having almost bought the Iphone 11 Pro, I say this more than meets my needs at a fraction of the cost. NOTE!!! You absolutely NEED to put on the case ASAP because it is a very slippery device and will fall out of your hands very easily.

Asus ZenFone 5Z ZS620KL is a rock solid, functional, phone. It has respectable battery life and everything works. The dual sim provides flexibility for international travel. I've had the phone for about a month and have no complaints. My only caveat is that I only wanted a solid, functional, phone... I do not care about 100 mega pixel selfies, filming music videos, or remotely controlling my sports car... so if you're used to spending over $1,000 for your phone I would completely discount my review.

Great Phone

This is the most amazing phone i have ever used. it is tough and reliable. I have been using this for about a year and half now and is still as good as new. No lagging, no crashing and quite secure. I have dropped it countless times but it is still looking great and works without a glitch. This is my 3rd ASUS phone. I started with the Zenfone 2 about 5 years back and got hooked, moved to the 4 and currently at 5. This phone performs well without even having to tweak anything much. The photo's are amazing, the video is quite impressive but takes up too much space, this is the one area ASUS needs to put a bit of attention to. this phone easily outperforms any phone in it's class in general performance and yet quite cheap compared to it's counterparts. I thought at this time i would have migrated to the 6 but nope, this thing is as robust as a phone can get. I have accidentally hit the screen with a sharp blade attached to a 550W drill whilst working at the farm, the thing fell a couple metres away. I was sure the thing was done for but nope, picked it up and there was not even a scratch on it. That was last year around March/April. Battery life is good generally but drains quick on 4G internet mode, unless if it's a Botswana problem. Otherwise on Wi-fi it does well on battery life. This is a worthy investment by all means.

The Asus ZenFone 5Z is easy to use and view, feels comfortable. It's intuitive and helpful, feels good in the hand. Setup was easy and helpful. The phone helps to organize and learn the functionality and features. The camera was able to produce good exposures in the woods or in full sun and indoors with natural light or artificial. Easy but complete. I'm happy with it. Thanks B H john hale

Massive Bang For Your Buck

At the time of my purchase, the phone had already been on the market for shot 1.5 years. $300 for this amount of performance is stellar. All processing performance benchmarks rival that of the iPhone X, but with twice the memory. Apps load quickly. No lag. The camera and camcorder are not as high-end as other options, but I didn't buy this device with that in mind. Still, it does adequately. The display is crisp and clear. Smooth and sleek design. You can't go wrong for a mid-tier unlocked Android phone.

Does the camera include face recognition?
Asked by: Donald
This phone does support facial recognition. It has some decent features that my higher end Samsung doesn't have - such as the ability to turn off wifi and bluetooth on a schedule (at night). The camera app is also much better than what Samsung offers. However, If you do some web searches, you'll find a decent amount of people that state the camera loses its ability to auto focus. It happened to mine - I don't recommend this phone - it clearly has a defect with the camera.

Is this phone compatible with the ifocus-M focusing motor on the Moza Air 2 gimbal? This requires a face detection auto focus camera to control the motor via Bluetooth when the phone is mounted on top of the gimbal's stabilized (DSLR) Camera.
Asked by: Donald
I meant that the camera inside the phone is mounted on top of the DSLR to use that phone's face detection ability to control the ifocus-m motor that is bundled with the Gimbal. This is a Moza software feature to provide follow focus to a DSLR that has no face detection (BMPCC 4K). I am not interested in mounting this phone alone on a gimbal at this time. I want to maximize my investment in a Moza Air 2 and a BMPCC 4K with manual focus lenses.
