ASUS has launched their selfie-focused smartphones and flagships in their Zenfone series back in September this year. Today we are taking a glance at one among the devices launched by the Taiwanese electronics giant, ASUS Zenfone 4 Selfie Pro, which was quite an overrated one. From the name itself, it is evident that the company has been trying to swim along the tide, by adding some sort of selfie-centric classification and dual-camera gimmick. Let’s do the review.

ASUS Zenfone 4 Selfie Pro Review: Introduction

As we have observed so far, 2017 is a year of displays and cameras. Everyone thinks of the display and camera of the newly launched smartphones, despite how much memory or clock rate do they carry under the hoods. So we can’t blame the product managers of the top-leading smartphone manufacturers being forced to design devices with dual-camera and taller displays. In the contemporary scenario, the ASUS Zenfone 4 Selfie Pro might seem like an apt choice made by the company, but while thinking out of the box, the device is just an overhyped thing and nothing more. Mounting dual-camera on the front with 4K shooting capability and some tweaks on the software side to show you fair enough won’t be enough to catch the market with ease in my opinion.

ASUS Zenfone 4 Selfie Pro Review: Camera

We would like to talk about the camera of the smartphone before anything else because the device name itself urges users to go for its camera. The smartphone comes with a 16MP rear camera, provides decent captures out of the lens. The camera is suitable for HDR landscape shots and closer macro captures. The focus range is not yet impressive, but less grains and noise even in low-light conditions. The capture speed is typically faster, but the process itself slow down in low-light in order to capture the better pictures but fails in capturing more light.

The USP, i.e., Unique Selling Proportion of the ASUS Zenfone 4 Selfie Pro is its dual-lens front facing camera which is capable of producing 24MP selfie snaps and 4K videos. However, the device sports only 12MP+5MP combo on the front. The trick behind the 24MP selfie is its DuoPixel nature, using a software trick to split the image taken with 12MP lens and enlarges into 24MP. You can see the difference between 12MP capture and 24MP DuoPix selfie capture below.

The secondary 5MP lens on the front is the one fixed for wide angle selfie shots, which has nothing to do with the 24MP images. But in the wide-angle selfie shots, you can capture a wide ‘group-fie’ or a landscape background selfie at 120-degrees.

The image quality of the selfies are just fair enough and not that impressive compared to other devices in the segment. The default ISO rate seems little exaggerated, so your selfies might seem whitened a lot in certain areas. The 12MP capture alone looks better in colour and ranges compared to the 24MP shots.

ASUS Zenfone 4 Selfie Pro Review: Design

The Zenfone 4 Selfie Pro smartphone is shipped with a familiar design, packed with a polished metal body. The rear camera is mounted at the middle, with a fingerprint scanner aside. At a glance, the back portion gives a resemblance of several LeEco (Letv) smartphones launched a while ago. The Horizontal antenna bands are visible on both top and bottom. Coming to the edges, the Volume rockers and power button sit so close but easily distinguishable and accessible without scrabbling much with fingers. Even on the front, we cannot see any ‘2017-type’ design elements, especially in case of the display. The ASUS Zenfone 4 Selfie Pro still sticks on to the old 16:9 standard screen, lacks the trending 18:9 display. Again, the company has managed to trim out the bezels to the least on sides. The Home button acts as a fingerprint scanner too, which ven can be used to pick the calls up.

Talking about the build quality, the device meets the standard quality which we could see on any typical smartphone below Rs. 25000. It has a typical micro USB port at the bottom, with speaker and microphone around to it.

ASUS Zenfone 4 Selfie Pro Review: Display

ASUS Zenfone 4 Selfie Pro has a 5.5-inch Full HD resolution AMOLED display, having deep, vibrant colour distribution and contrast ratio. The backlit brightness is quite good, and almost visible in outdoor conditions. But in night conditions, the lowest brightness even seem brighter compared to its rivals. Although, if you are looking for an ultra sharp colour sensitive display, the Zenfone 4 Selfie Pro will disappoint you, at least to an extent. This affects the images taken in the smartphone. There is an always-on display feature, which makes use of the AMOLED panel.

While seeing from the device, some outdoor pics may look vibrant, yet not that impressive while viewing on another device (smartphone/TV/PC). However, it is not very bad to look on to the display, as the colour distribution seems impressive for most of the users. As we have collected typical user reviews among our several readers and natives, the display is an “OKAY” and “EXCELLENT” for many.

ASUS Zenfone 4 Selfie Pro Review: Performance

The smartphone is powered with Qualcomm’s Snapdragon 625 SoC clocked at 2.0GHz, paired with 4GB of RAM on board. There is no need of introducing the Snapdragon 625 Chipset, as it powers most mid-range smartphones available in the market. It is well-known for its efficient performance and power delivery, with best temperature control management.

The overall performance of the smartphone is not so desperate, also it scores well in benchmarking platforms. The 4GB of RAM is literally good enough in managing the background tasks and window processes concurrently without any lag.  Here are the specific benchmark results of the review unit we have received.


ASUS Zenfone 4 Selfie Pro Review: Battery

If you have used any of the ASUS devices before, you must have complained about the battery life. Luckily, this time the company has improved the battery life of the device, even with the typical 3,000mAh battery (Thanks to the UI optimization and efficient Snapdragon 625). On an average usage with often gaming and mobile data turned out, I got an average battery life more than 10 hours on a daily basis. The result is counted average, I felt.

The device package provides a 10W Travel Charger adapter but does not even support fast charging. It is very disappointing that the charging rate is desperately slow, as the smartphone takes nearly 2 hours to boost the battery from 0 to 100%.

ASUS Zenfone 4 Selfie Pro Review: Software

ASUS’s own Eco system ZenUI 4.0 skinned on top of the ANdroid 7.1.1 Nougat Operating System. The user experience of ZenUI becomes fluent that it ever has been. The Quick Settings panel is similar as before, but the icons have made beautified a little. The new app drawer brings more comfortable access to apps and makes the Home screen clean. There are many gesture and button options available on the device which are customisable. Pressing thrice on the power button will trigger SOS mode and sends your location to the prefixed contacts.

The ZenUI 4.0 also lets you use Cloned Apps, Split Screen and many other “ZenUI-only in-built” features. Making an account of bloatware apps, the smartphone has a decidedly less number of pre-installed apps or programs, which are even highly useful for a typical smartphone user. The Mobile Manager app and Themes App are helpful in managing the device space and customizing the UI.


The Zenfone 4 Selfie Pro is a good device if you prefer a selfie centric smartphone. But, we don’t think someone is going to purchase a smartphone for Rs. 23,999, just to take selfies. So if your preferences are even broad, you should consider any other smartphones in the same range. You have some better options like Moto X4. However, the choice is up to you, we are just helping you to decide. Since the battery life and hardware performance is not that great, there is no point in buying this device. Also, it lacks good build quality.
