Cubot King Kong 3 Smartphone Review

Florian Schmitt, 👁 Florian Schmitt (translated by Stephanie Chamberlain), 04/03/2019

The return of the king of the apes. Catchy name, outdoor smartphone, second generation: The successor to the Cubot King Kong promises to be a budget yet high-quality-looking rugged smartphone. We're excited, are you? Then read on quickly.

Cubot King Kong 3

After King Kong comes King Kong 3. That's not exactly logical and we couldn't determine why there's no King Kong 2 either. In last year's review, we found the predecessor Cubot King Kong "good" and the successor promises some improvements: The most important thing is likely that LTE is finally on board, there's a modern SoC, a dual-camera setup on the back side, an even larger battery and the smartphone is reported to be rugged.

In exchange, the King Kong 3 is more expensive than the King Kong, but it is still quite low-priced for an outdoor smartphone: This budget offering can be found online right now for about 210 Euros (~$236).

Before diving right in, we'll establish the comparison devices against which the King Kong 3 will be measured: Alongside the predecessor, we chose the Ulefone Armor 6, the Elephone Soldier and the CAT S31.

Case – Heavy outdoor smartphone

Cubot remains faithful to the design philosophy of its outdoor smartphones: visible screws, metal elements on the sides, and a back side that isn't flat but becomes thinner towards the middle. The King Kong 3 immediately reveals that it's a stable smartphone, and weighing 280 grams that it's also quite heavy. When compared against its predecessor, both the weight and display size have increased. A 5.5-inch display in a slimmer 2:1 format is to be found now, so that the smartphone has become a bit narrower.

The fact that the screen was relatively unprotected seemed to be an issue with the King Kong. On the King Kong 3 there's now at least a minimally raised bezel and the display also comes with a factory screen protector. However, other manufacturers have given their screens more thought and equipped them with much higher protective edges than the ones found on the King Kong 3. The display would have a lot to endure, should it fall on an uneven surface such as pebbles.

The colorful decorative elements on the case still exist, but it's no longer necessary to unscrew it in order to get to the SIM card. It can now be accessed through an ordinary drawer.

According to the manufacturer, the case is IP68-certified, making it resistant to water and dust. Furthermore, it should be usable at extremely low and high temperatures without problems. Irritably, a card in the package advises against using the device at very high temperatures or in harsh environments, which contradicts the manufacturer's promise.

Connectivity – More storage in the King Kong 3

The King Kong 3 is significantly more expensive than the first King Kong and that's also noticeable in its configuration: There's now 64 GB storage and 4 GB RAM, which is by all means adequate for a mid-range smartphone. Not all contenders can keep up with this, but the Chinese devices from Ulefone and Elephone offer even more storage.

The smartphone is also dual-SIM and provides a microSD slot, which occupies one of the two SIM card slots, so that users will have to choose between having two SIM cards or expanding storage.

Software – Outdated security

The operating system is a partially up-to-date Android 8.1; the security patches from November 2018 are, at the time of writing, already outdated. An update is not in sight so far. Cubot opted for pure Android for the western version of the smartphone, which fortunately comes without bloatware too.

However, it's annoying that a lot of streaming content can only be watched in lower resolutions because of the lack of proper DRM support from the manufacturer.

Communication and GPS – LTE in Cubot smartphone

While the predecessor only offered 3G, the King Kong 3 is now also capable of LTE. The maximum download speed reached a decent 300 Mb/s. Reception is decent in buildings in the city, but it is not great. This could be due to the metal used in the case, which can inevitably hamper the signal.

Regarding Wi-Fi, the King Kong 3 is slightly faster at receiving data than its predecessor, but at around 60 Mb/s, it still behaves like an entry-level smartphone. The Elephone Soldier and the Ulefone Armor 6 offer higher speeds on the other hand.

GPS tracking in buildings is not possible with the King Kong 3, but this works almost immediately outdoors and the accuracy is quite good at five meters.

In our practical test doing a bike lap, we used the professional navigator Garmin 520 as comparison device. The Cubot King Kong 3 didn't show any massive signal drops. Although the professional navigator didn't represent the difficult round trip correctly, the King Kong 3 was overall still less accurate than the Garmin device. Nevertheless, accuracy is good enough for recreational purposes and if an exact location isn't required.

Telephone and call quality – Buzzing noise from time to time

The phone app is the standard Google app, so Android veterans should quickly feel comfortable with it.

Call quality is good, but the ear speaker makes a buzzing noise at maximum volume; lowering the volume a bit fixes this and sound quality is good. The microphone also delivers good results and voice quality is clear both when talking quietly or louder. Sound output is also quite loud and of good quality when on speaker. The microphone has some issues in this case though: On one hand, there is a hissing noise, on the other hand, it's too sensitive, so that there's a buzzing sound even at medium volume. The only way to get clear voice quality here is to talk very quietly.

Cameras – Grainy pictures from the Cubot smartphone

Front-facing camera sample
Front-facing camera sample

Things have changed a lot in the camera department since the Cubot King Kong: In the new model, there's a dual-camera setup on the rear. There's a 16-megapixel main camera and a 2-megapixel secondary camera to achieve focal blur. You can tell at first glance that picture quality is much better than on its predecessor. However, pictures also look very grainy in detail. That's relatively noticeable in photographs of surroundings. Under low light, images quickly become blurry. HDR shots can also be taken but you'll have to give the smartphone a second for it to process them.

The front-facing camera takes passable pictures with its 14 megapixels; dynamic range isn't particularly high and we could also see a lot of graininess here. There's also no auto-focus, so that you need to find the right distance from the target in order to get a sharp image.

Videos of up to 1080p and 30 fps can be recorded on the main camera. The auto-focus is very slow in this case, it often needs manual assistance. Exposure varies significantly as ambient lighting changes.

Image Comparison

Choose a scene and navigate within the first image. One click changes the position on touchscreens. One click on the zoomed-in image opens the original in a new window. The first image shows the scaled photograph of the test device.

Images also appeared very grainy in our lab under controlled lighting conditions, especially on large color areas. Image sharpness was decent and barely decreased towards the edges. 

Colors look a bit too washed-out though.

Accessories and warranty – Relying on the retailer

The package only contains the essentials: a charger, a USB cable and a SIM tool. The quick-start guide is only available in English. Since we're dealing with a standard Android device, you'll find general tips on it. The software is completely available in German too. On another note, an adapter for the USB-C port isn't included. Users who want to connect headphones or make use of USB-OTG will have to acquire a separate adapter.

Cubot promises a 12-month warranty on its website and also offers after-sales support. However, there is no option to contact the company directly and the smartphone would have to be sent to Cubot at your own expense, presumably to China. When buying from a European retailer, you'll have the chance of claiming a repair through the warranty, but after six months the following applies: The buyer must prove that the product was already defective when it was delivered. In this case, you'll usually depend on the retailer's goodwill.

Input devices and handling – Smartphone with programmable hardware button

The touchscreen on the King Kong 3 comes with a screen protector that's hard to remove. On one hand, it protects the screen, but on the other hand, it feels rough to the touch. Overall, however, the touchscreen reacts with precision and reliability. There is no glove mode and, as with the Cubot King Kong, it bothers us that menu navigation is limited to on-screen buttons only: If you wear gloves at work or have wet hands, you might not even be able to perform some basic tasks on your smartphone.

The fingerprint sensor on the back works reliably. Google's GBoard is used as the keyboard app, making for a solid typing experience.

The hardware buttons are a real highlight on the King Kong 3, they are very large and therefore easily usable, and they seem of high-quality and work with precision. On the left side of the case, you'll even find a programmable button, which is very good.

Display – Room for improvement

Subpixel array

The 18:9 display comes with HD resolution but offers only moderate brightness, which is incidentally also quite unevenly distributed along the screen. With an average of 378.9 cd/m², the maximum brightness is even significantly lower than on the Cubot King Kong. This is very annoying for an outdoor smartphone since it's supposed to be usable outside.

The competition not only delivers displays with considerably better brightness but also even with substantially higher resolution in some cases, like on the Ulefone Armor 6 or the Elephone Soldier, for example.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9266 (minimum: 43 - maximum: 142900) Hz was measured.

At least there's a good black level, which produces decent contrast. We also found that colors looked bright on the display.

We noticed a clear blue tint when looking at the screenshots provided by the CalMAN software. This was accompanied by a marked deviation from the color-space specifications, which resulted in inaccurate colors. Professional users will be particularly bothered by this.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 13 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 60 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 23 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 65 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.6 ms).

No PWM was identified, at least. However, outdoor use showed that the display reaches its limits in bright environments. Viewing angles are decent, but shifts in brightness at lateral angles are noticeable.

Performance – A clear step ahead

When it comes to performance, the King Kong 3 is a clear step ahead of the original King Kong: The MediaTek Helio P23 performs significantly better and is worthy of a mid-range smartphone. Compatibility with apps has also been improved; benchmarks that wouldn't even start on the King Kong can now be run. There are also limitations though: Occasionally, apps freeze or misbehave. The slightly older AnTuTu 6, for example, doesn't start, but more modern benchmarks do. So you should thoroughly test important apps before buying.

* ... smaller is better

It's not uncommon at this price point to find that the King Kong 3 only supports eMMC flash memory. However, the comparison devices from Ulefone and Elephone offer considerably faster internal storage. Compared to the King Kong, our review device makes a huge leap forward in terms of storage speed.

We tested the speed of the microSD reader with our reference card, the Toshiba Exceria Pro M501. The King Kong 3 showed its very fast side here. It's a shame that our review device doesn't support cards using the ExFAT format.

Games – King Kong 3 is suitable for gaming

Current games like Arena of Valor can be played on the King Kong 3, and performance is good enough in many games to get smooth gameplay. However, we observed a crash in Arena of Valor when using the menu, but the app is in general not the most stable though. In Temple Run 2, we could assess how precisely the touchscreen and position sensors reacted to input, we didn't have anything to complain about in this regard.

Temperature

The device showed limited heat build-up under load: The maximum temperature measured on the top area of the smartphone was 37.6 °C. Temperatures in idle usage were between 30 °C and 32 °C. The device only ever becomes moderately warm, thus never getting uncomfortably hot.

Speakers

Pink Noise speaker test
Pink Noise speaker test

The first things to notice in our test graphics are the strongly over-emphasized high frequencies. In addition, the mono speaker is mounted on the back, where it can easily be covered. That can only mean trouble, right? Surprisingly, no: Sound is sufficiently loud and pretty acceptable due to the balanced mids. If you're only interested in listening to music from time to time, the King Kong 3 can handle that well.

The King Kong 3 doesn't include a 3.5 mm audio jack. Instead, sound is carried over the USB-C port. Unfortunately, an adapter for 3.5 mm plugs isn't provided, but several adapters we tested worked without any issues, and audio was clear. Sound output is also possible through Bluetooth 4.2, which works equally well.

Battery runtime

With its massive 6000 mAh battery, the Cubot King Kong 3 overshadows all comparison devices. The actual runtime? This is also impressive: You can browse the web for over 21 hours until the device needs to be plugged in again. That's more than enough for several workdays.

Thanks to the 18 W fast charger, the smartphone can be fully charged again in well under 2 hours.

Verdict – The new king of the apes does it better

In review: Cubot King Kong 3.
In review: Cubot King Kong 3.

The ape makes a big leap forward; King Kong even skips the model name "2" and lands directly in the mid-range. In fact, in many ways, the King Kong 3 doesn't seem like a successor to the Cubot King Kong, but more like an extension of the model range in a completely different class. The King Kong 3 is clearly more expensive than its predecessor, but in return it offers significantly more power, LTE, more storage and an eternal battery life. In this way, 249 Euros (~$280) seems to be a reasonable price, even when the competition, primarily from China, doesn't rest and has equally strong offerings between 200 (~$225) and 300 Euros (~$337).

The new King Kong inherited some weaknesses from its predecessor though: In our opinion, the screen is still not adequately protected. Using the screen when it's wet or with gloves on is almost impossible, and in general the protection doesn't seem completely trustworthy. This is also emphasized by the manufacturer, who cautions against usage in harsh environments.

Good mid-range outdoor smartphone with long battery life. However, it is only partially suitable for harsh environments.

Users who only need general protection against water and dust, and also like the phone's design, will find a good overall package in the Cubot King Kong 3. But some annoyances must be accepted: Software updates come rarely, if ever, and the quality of the support you get will depend on the retailer you choose.
