ASUS last week released the brand new ZenFone 7 and ZenFone 7 Pro series, and today’s we’re ready to publish our testing of the company’s newest “mainsteam” flagship device.

This year’s ZenFone 7 series, consisting of the regular ZenFone 7 and the ZenFone 7 Pro are sticking to the quite well received and innovative flip-camera design, improving upon its specification by adding in an extra camera module. We’ve also seen key specification improvements on the part of the phone itself, with an important shift from an LCD screen to a new 90Hz AMOLED display, as well as adoption of Qualcomm’s newest Snapdragon 865 and 865+ chipsets.

This year, the company is also releasing two variants of the phone – beyond higher DRAM and storage configurations, the higher-end model features a higher-binned SoC as well as differentiates the camera systems by exclusively employing OIS – which is an interesting way to segment things.

Starting off with the hear of the phone, the ZenFone 7 and 7 Pro employ Qualcomm’s latest Snapdragon 865 SoCs and are thus 5G-capable devices thanks to the X55 modem. ASUS here employs the newer higher-performance Snapdragon 865+ on the 7 Pro model which brings with it 10% higher CPU and GPU performance thanks to the increased frequencies of these IP blocks.

Further variations between the regular ZenFone 7 and the 7 Pro is in the DRAM and NAND storage department. The regular variant comes with 6GB of LPPDR5 and 128GB of UFS 3.1 storage, whilst the Pro gets respectively 8 and 256GB.

The key selling point and differentiating factor of the ZenFone 7 as opposed to other phones in the market right now is the fact that it employs a full-screen display without any notch or camera cut-out, enabling a seamless screen experience without distractions.

A big upgrade this year compared to last year’s model is the shift from an LCD to an OLED screen, which makes this year’s model significantly more attractive to users. The 6.67” screen features a 2400 x 1080 resolution in a 20:9 aspect ratio, and features a 90Hz refresh rate capability.

Although 90Hz isn’t the very top of the line for 2020, it’s still a huge improvement over other 60Hz phones and ASUS did manage to employ a 200Hz sampling touch controller which has a large impact on fluidity and responsiveness when you interact with your phone.

The back of the phone sees a glass back-panel which comes either in a “Pastel White” (pictured) or an “Aurora Black” colour variant. The phone lacks wireless charging.

It’s to be noted that this is a very large phone that is in line with the iPhone 11 Pro Max and the Galaxy S20 Ultra in terms of footprint, quite a bit larger and chunkier than the ZenFone 6. This is something that ASUS actively acknowledges as being a deliberate design choice so that that they could fit in more components and a larger battery, as well as enable the various antennas requires by 5G connectivity.

The camera setup now features triple modules. As the primary main camera, we’re seeing a 64MP IMX686 sensor with 0.8µm pixels that by default bins down to 16MP thanks to its quad-Bayer colour filter layout. The optics feature a large f/1.7 aperture.

The ultra-wide-angle also adopts the same setup as on the ROG Phone III with a 12MP IMX363 with 1.4µm pixels and dual-pixel phase detect focus ability. The optics have an f/2.2 aperture with a 113° wide viewing angle. Unusual is that it features auto-focus ability which means that this module can do dual-duty as a macro module since it enables super close focusing abilities.

New to the setup is an 8MP telephoto module which offers 3x optical magnification which thanks to multi-frame interpolation can be digitally cropped and magnified to up to a useable 12x zoom in the camera app. The optics here feature an f/2.4 aperture.

On the ZenFone 7 Pro the main camera as well as the telephoto module feature OIS in their modules, whilst the regular ZenFone 7 doesn’t feature this. We haven’t seen such segmentation in some time by a vendor, but it’s one of the cost-cutting measures that ASUS has decided to make for the cheaper model.

The flip-camera externally looks familiar with what we’ve seen on the ZenFone 6, however ASUS has greatly improved the internal mechanism of the newer generation module. The new module employs a new motor that is capable of 2.2x the torque of its predecessor even though it’s 40% smaller.

ASUS has also replaced the complex 49 signal and power cables that connect the various camera modules to the mainboard of the phone with a new 18-layer flexible printed circuit cable that promises to be twice as durable even though the total signal traces has increased to 110 outputs. ASUS claims it’s good enough for up to 200000 flips, which is 100 flips a day for over 5 years.

I’ve never had the pleasure to get a hands-on with the ZenFone 6, but the camera mechanism on the 7 series feels very solid and robust.

A new feature to the flip-screen is its ability to position itself at intermediary angles from within the camera app, giving you different capturing angles, which are essentially impossible for any other phone on the market.

Beyond your typical fully-flipped 180° setup in which the cameras can serve as high-quality frontal selfie cams, the module also can sit at a 90° or 135° angle. The phone’s panorama capture feature takes advantage of the flipping module to sweep the landscape whilst you hold the phone steady.

The phone is quite thick at 9.6mm, but that’s mostly due to the 5000mAh battery that’s included, which also bloats up the device to a 230g weight.

ASUS has dropped the 3.5mm headphone jack this generation. Their rationale about the change was that due to the increased internal footprint required by the 5G antennas they had decided to do away with the jack to be able to save on space.

One thing that’s unique on the bottom of the phone is that it features an LED notification light on the left of the USB-C port. ASUS here said that they had to remove it from the front top of the screen due to the reduced bezel size, but didn’t want to abandon the light completely, so they just repositioned it to the bottom of the phone. This is actually quite useful and a more power-efficient way to handle things than an always-on-display so I do appreciate this detail.

The left side of the phone features a long SIM tray that is able to house two nano-SIMs as well as a micro-SD card simultaneously.

The right side sees a traditional volume rocker, as well as a triple-function power button. ASUS opted for a capacitive fingerprint scanner from Goodix integrated into the power button – it’s one of the cost-cutting measures allowing the ZenFone to hit a lower price-point. Beyond the traditional single-press power button function, dual-pressing the button calls up the Google assistant, and you can customise or disable this functionality.

    Introducing the ASUS ZenFone 7 with twice as much gimmicky camera market differentiator at a cost of functionality as last year's model!
  • RollingCamel - Tuesday, September 1, 2020 - link

    I would suggest a revisit the camera performance for a number of phones while using GCAM. Should be an interesting read.

    Here is the link for Zenphone 7/pro GCAM files.

    i was hoping to see the panorama mechanism in action. that’s a really cool idea.
  • eastcoast_pete - Tuesday, September 1, 2020 - link

    Thanks Andrei! With video recording being a key interest of mine, the lackluster performance disqualifies this phone for me already. Too bad ASUS spent all their engineering time on gadgetry, and not on making the camera function what it could and should have been.

    I know ASUS is a Taiwanese company but does anyone know exactly in which country this phone is produced / assembled / made?

    Sir I need Asus Zenfone v 520 kl unit

    I think Asus are losing their way. They are not a premium manufacturer for 2 very important reasons. Their software and their support is terrible. I have had many Asus products but I am now seriously going off them. Their hardware is always great, I mean really good, but their software is often buggy and most importantly of all, is never maintained for as long as you might expect and is often abandoned way too quickly, even by budget manufacturer standards, never mind a premium one. At least unlock the bootloader or something so we can keep using the products. I know they have done this for some products but it's too random which products get it and which not. One of the most horrible examples come from their tablets, specifically the Z500KL which I own (zenpad 3S 10 LTE). It was a very expensive tablet, over £300 at the time and was vertigo made and functions well to this day, after 3.5 years of heavy use, yet it shipped with android 6 which was already basically obsolete, then it got 1 android version update to 7 and that was it... Almost no security updates either. They have released a bootloader unlock for the Z500M, the non LTE version, but nothing for the Z500KL. With this kind of attitude, they will never be accepted as a premium phone manufacturer. I have to say though that I do like the flat screen on a top end device. I hate the curved screens and if it wasn't for the software and the ridiculous price, this could well be an attractive set of phones. Also, no headphone jack. Pity...

    One of the main issues I have with Asus phones is software rather than hardware. Phone runs fine until you get an update that screws up a major issue like sound or display or even brick your phone completely like what happens to my zenfone 4.

    Also Asus after zenfone 4 started to cut cost on the OS but removing the customization features they used to provide
  • gamer1000k - Tuesday, September 22, 2020 - link

    I've got a Zenfone 6 and was excited to read about the 7 until I read that the headphone jack was removed, and the price went up 50%. Hard pass.

    I don't get all these salty comments. I bought a Zenfone 7 Pro and I LOVE this device. The phone feels extra premium. The camera is great. The performance is superb. Sound is great, call quality is great, signal/reception/GPS is great. Everything is awesome about it, I really have NO clue why people are complaining all this much.

    Before this phone I've had a OnePlus 7 Pro, Mate 20, then a Note 10+, then a Xiaomi Mi 10T Pro. This is the best phone (both software and hardware wise) out all of them, hands down.

    No, ASUS have not paid me a cent to make this post. I just truly believe this phone is awesome. I wish they'd have used IPS LCD on this phone as well (just like on the 6), but whatever, it works.
