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.

    Seriously, doing away with the headphone jack in exchange for 5G. Might as well go with Samsung Reply

    Yeah they say 5G antennas are small, sometimes they omit the fact that you need more than a dozen of them. Reply
  • melgross - Tuesday, September 1, 2020 - link

    You need from three to five, depending on whether you’re using sub mm bands or not, not dozens. Reply

    It's 100% b.s LG V60 and Sony Xperia Mark II both of them are 5G and LG even has full U.S band support with mmWave technology as well and has a superior Audio performance from the standalone RFI shielded high end ESS9219 DAC chipset (ESS9218P was being featured in LG phones from V30 and up) and both of them have IP68 rating along with Qi charging too. The fact that Note 20 gets a full blown Silo for the S-Pen makes so fucking ground for these lying bastards. Removing jack is saving pennies and forcing them to buy accessories which also die out due to the Li-Ion technology. Reply

    Can anyone describe how to understand the ∆E ITP and ∆E ITP LC value?

    I did use ∆E 2000 with Gamma 2.2 for long time, but even searching in google, the data just saying about Rec.2100, EOTF, PQ, HLG and ITU-R....

    I knew ∆E ITP is a part of Rec.2100 HDR...but, the info I really want to know is the relationship between ∆E ITP (LC) and real world.

    ∆E 2000 < 1:Great and almost perfect
    ∆E 2000 < 2:so hard to see the difference and it's good enough for professional users
    ∆E 2000 < 3:good for general users

    ∆E 2000 < 5:ok for general users but still has noticebal color difference
    ∆E 2000 > 7:esay to see the color difference

    Can ∆E ITP and ∆E ITP LC use those standards (0 ~ 1 ~ 2 ~ 3 ~ 5 ~ 7 ~)?

    dE ITP is a new standard that takes into account more modern reproduction formats such as HDR. Generally ITP is a little more sensitive than the 2000 standard to colour deviations: https://kb.portrait.com/help/about-deltae-e

    dE ITP LC as I use it in the new reviews is simply a luminance compensated value, meaning that the error value ignores the luminance error and only looks at hue and chromacity. This makes sense for example in this review here as the ZenFone is targeting a 2.4 gamma by default, however our measurements are against a 2.2 gamma target. So the dE LC values are always going to be lower since it ignoers that part of the colour inaccuracy.

    Under dE ITP of 1 it's imperceptible, under 3 it becomes acceptable when not viewed next to each other, and over 10 means it's horribly wrong.

    Thank you @Andrei, the reply is really helpful!!!
    Now I can read the Calman's color calibration charts and info well based on that very useful knowledge, and easy to judge which device can provide great display quality.

    Two more things I was wondering in this article:
    1. The devices that Anandtech had reviewed such as Mate 20, iPhone XR, Xperia 1 even Surface Pro or XPS13, will get the updated display quality review based on the new delta ITP (LC) standard?
    2. ASUS ZenFone 7 Series has a telephoto camera that has very similar spec to HUAWEI and Honor devices' (OV8856, 1/4.4", 1 um, F2.2, 80 mm{, OIS}, with terrible PDAF). It brings 3X Optical Zoom to ASUS smartphone first time and I'm expecting the 3X OZ camera can shows on ZenFone 7 Pro's review. This will be interesting if we have a comparison between ZF7P, 1+7P, M30P, P30 those who having a 3X OZ camera.....is there any opportunity to see this kind of comparison?

    in the end, I really thank to AnandTech's great quality reviews!!!

    "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"

    Did they forget about the headphone jack?

    >made phone huge for more components
    oh yeah we couldn't throw the 3.5mm jack in there, not enough room. The 5 gees, you know, they take up too much space.

    I thought that the unexpectedly low battery life might be because this phone did mm-wave 5G. Bit no: having dug up the specs, the highest 5G frequency band it can handle is 3.3–4.2GHz. Reply
