Thermal imaging is a technology that have found a lot of uses in the professional setting. From engineers, first responders, construction workers, safety inspectors, thermal cameras uses knows no bound

The V20 offers excellent value and has a more elegant yet rugged design than we’ve come to expect. The AMOLED screen is stunning, but limiting it to Widevine L3 DRM means that you can’t use it to view Netflix or Disney+ in better than 480p.
Gorgeous OLED display
Night vision camera
Excellent battery life
Uncluttered Android 11
Widevine L3 = 480p streaming
Annoying USB-C cover
Previous Doogee phones we’ve covered were probably trying a little too hard in pushing the ruggedised aspect of those devices by making them look like military equipment.
Those responsible for those devices took the backseat on the V20 or have realised that customers want rugged phones that look like more attractive non-rugged designs.
Yes, it still has that go-anywhere vibe, but the V20 has more subtle styling than we’ve seen previously from Doogee and signals a transition to aesthetically considered phones.
On the back of the V20 case is a surface finish that looks like carbon fibre. It’s merely a finish, and this phone has a conventional construction of polycarbonate and aluminium.
Another continuity with previous designs is that the V20 is biased towards right-handed customers, with a thumb-friendly fingerprint reading button on the right that would be less convenient for those who are lefthanded.
If this impacts you, the best option is to use face unlock if you are happy with using that.
Like the V10, this design is IP68, and IP69K rated, allowing it to handle dust and water with limited time and depth immersion in liquid, assuming all the seals are intact.
The two significant points of ingress are the dual SIM card slot and USB-C port, with the USB port being the genuine concern. A rubber plug covers this port when not in use that manages to always get in the way of inserting the USB-C cable.
While the plug fits snuggly, those wanting to keep this phone from getting any water in it would be advised to leave it firmly in place and use the wireless charging that this design supports.
Easily the most eye-catching feature of the V20 is the wonderfully colourful OLED display with a natural resolution of 1080 x 2400. The contrast ratio on this screen is an incredible 80000:1 and displays 105% of the NTSC colour gamut.
One peculiarity with the screen is that to get the biggest vertical display coverage, the front-facing camera is under the display, and a small hole has been cut through it. Not exceptional, but it's something you might not expect to see when viewing a video full screen.
This also isn’t the only display on the phone, as a small 1.05-inch panel to the left of the triple camera cluster on the back. Being so small, its practical uses are limited.
But it can be set to show a clock, reveal who is ringing you or provide a quick means to control media playback.
The issue here for us is that we’re not inclined to place our phones face down, mainly to protect the screen, and therefore we’d not be looking at this teeny display anyway.
The camera cluster that combines three sensors into one image processing solution is arguably more useful. The top resolution is achieved via a 64MP main camera. Alongside that are a 20MP night vision sensor and an 8MP wide-angle camera that is useful for creating blurred backgrounds. Still images can have a maximum resolution of 9248 x 6944, and the Doogee camera app allows for HDR, panoramics, and the usual social media-friendly features.
Our only disappointment about the camera is that given the huge resolution of the sensor that this phone doesn’t support the capture of 4K video, offering only 2K @30fps and no other framerate options.
High-end phone brands have been migrating to custom ARM SoCs to differentiate their devices from competitors.
Doogee isn’t one of these and has settled on the Mediatek Dimensity 700 MT6833, an eight-core chip fabricated on a 7nm process that they previously used in the V10.
An evolution of the Mediatek Helio P70 Octa-core processor, the MT6833 features an integrated 5G modem and a radically different core structure.
Many previous Mediatek octa-core designs used two groups of four cores, this chip sports two high-performance ARM Cortex-A76 cores, clocked to 2.2 GHz and six power-efficient 2GHz Cortex-A55. They make an 800 series SoC that uses the old four-and-four core model, but the 700 series offers more power saving potential.
The narrower tracks and heterogeneous multi-processing aspects of this design allows for an excellent overlap in the objectives of raw performance and extensive battery life.
When combined, as it is, in this design with 8GB of LPDDR4X RAM and 256GB of inbuilt storage, it provides a smooth and responsive user experience almost irrespective of the number of apps they install or the demands they make on the phone.
What got removed that the V10 had is the infrared thermometer, a handy feature of that design.
The Doogee V20 that was sent to us for review came with the following hardware:
CPU: Dimensity 700 MT6833 Octa Core 2.2GHzGPU: ARM Mail-G57 MC2RAM: 8GB LPDDR4XStorage: 256GBScreen: 6.43" AMOLED FHD+ DotDisplayResolution: 1080 x 2400SIM: Dual Nano with standbyWeight: 296gDimensions: 170.4 x 81 x 14mmRear camera: AI Triple camera (64MP+20MP+8MP) with Nightvision modeFront camera: 16 MPOS: Android 11Battery: 6000mAh
But the one feature of this phone that is impossible to ignore is the screen. With deeply saturated colours and a maximum brightness of 500 nits, the 6.43" AMOLED FHD+ DotDisplay offers a 20:9 ratio panel that is a delight.
However, as wonderful as the screen is, it’s difficult to get the most from it due to an oversight.
With such a large and vibrant display combined with good battery life and 5G connections, this should be the perfect phone for streaming. But with only Widevine L3 software DRM, 480p is the maximum available resolution on most streaming platforms, crushingly.
Why this piece of the V20 puzzle is missing, we can’t say. For many potential customers, this limitation undermines the desirability of the V20 and other phones that don’t offer L1 level DRM.
Sadly, the DRM issue is likely to be a hardware problem that can’t be addressed with a firmware enhancement.
We did find one excellent use for this phone and its colourful screen, and that was for drone flying. The brightness of this panel and the performance of the V20 is ideal for drone flyers that might encounter rain or snow while enjoying this hobby. However, the reflections on the screen can be an issue without applying an anti-reflection filter to it.
Performance and in use
The performance offered by the Mediatek Dimensity 700 MT6833 on this phone is very good. Comparing these benchmarks to the Doogee S88 Pro from 2020, the V20 is almost twice as fast in every test, with the possible exception of HWBot Prime test.
The 3DMark results are a strong indication that the V20 is a good choice for those that like to game on their devices or use apps with 3D rendering functionality.
While the battery is smaller than the previous V10 offered, the operating life is relatively close, with a typical use pattern delivering two working days before a recharge is required.
The reduced battery capacity makes the V20 lighter, but not substantially. At nearly 300g, this isn’t a lightweight device, and it needs to be secured in a pocket to avoid momentum launching it unexpectedly.
Unlike some phone brands we can mention, Doogee has a relatively light touch in customising the Android 11 installation on this phone, and it is almost vanilla. It, therefore, comes with all the Google applications pre-installed and has full access to the Play store.
The only negatives we experienced was the awkward USB-C cover, the lack of 4K video recording, and the software-based DRM that scuppers HD video on most streaming services. With this AMOLED screen, it’s a tease to watch HDR content on YouTube to see the glory of 1440p playback, and with the proper DRM, how Netflix and others might have looked.
In all other respects, the performance of this phone is excellent unless the application is expecting to find a Trusted Execution Environment (TEE) for DRM encryption.
This is how the Doogee V20 performed in our suite of benchmark tests:

✕Does not support some US CDMA carriers
I do like the Doogee range of phones -- both rugged, modular, and slim models. Now Doogee has added a couple of new models to its rugged range that I was keen to try.
The Doogee S86 Pro is a nice rugged phone running Android 10, which is comfortable in my hand. Some Doogee models are only comfortable if you have large hands and tend to feel 'edgy' and sharp in my smaller hands.
The S86Pro seems slimmer to hold at 81.2mm wide, taller at 164.6mm, and not too thick at 16.8mm. This depth squeezes an 8,500mAh battery into its casing, so the phone weighs a comfortably heavy 323g. You definitely know when it is in your pocket.
Inside the box, the S86 Pro comes with a charger, a type-C USB cable, a fabric lanyard handle that attaches to the bottom of the phone to prevent the phone from dropping out of your hands and falling on the floor.
There is also a small tool to pull open the SIM card slot and prevent you from snapping your fingernails. There are also two blue screens -- which Doogee says are 'anti-explosion' films. I suspect this film is actually a shatter protector if you break the display glass.
The phone has a 6.1 inch Corning Gorilla Glass LCD screen with a resolution of 1560 x 720px and an aspect ratio of 19.5:9. Its IP68/IP69K standard means that it is waterproof, even coping with immersion in water up to 1.5m for up to 30 minutes.
Doogee offers the S86 Pro in three colours: black, black with orange trim, or black with red trim accents. The trim is unobtrusive as the body of the phone is mainly black.
Inside, the S86 Pro is powered by an Helio P60 octa-core, four cortex-A53, and four Cortex A73 running at up to 2.0GHz. Its graphics chip is an AMR Mali G72, running at up to 800MHz.
It comes with 8GB RAM and 128GB ROM, so there is a lot of storage space on the phone. You can extend the storage with a TF card up to 256GB capacity.
There is a dual SIM slot on the left-hand side of the S86 Pro with a silicone ring around the SIM to prevent water ingress. There is also a custom function key for you to configure or use for the SOS feature. The function key can be used to take a screenshot or play any installed app with a single, double click or a long press of the button.
The right-hand side of the phone has the volume buttons, the power button and the fingerprint sensor. The fingerprint sensor location means that it is easiest to use your thumbprint if you are right-handed -- but you have a range of unlocking fingerprint options if you hold the device in your left hand.
The top of the phone has a headphone jack slot, covered by a tightly fitting silicone seal, and at the bottom of the phone, there is a USB-C charging slot, again covered with a silicone seal.
On the back of the phone, there is what looks like four camera lenses. One of the lenses is an 8MP wide-angle lens with a field of view of 130 degrees, and the main camera is a 16MP camera.
There is also a 2MP portrait or macro camera and an array of LED flashes under the lenses. However, the circle at the top right of the camera array is not another lens but a thermal sensor. The front camera is 8MP.
A big selling point for this phone is its innovative temperature sensor. Point the camera at someone's forehead, tap the measure button and wait for the vibration to get an accurate temperature reading in either Fahrenheit or Celsius.
The app will record the measurement of human recordings in its log. You can also measure the temperature of objects -- like pets or hot liquids. It is quite a neat feature -- especially in these times.
The phone also has NFC, which supports Google Pay and supports both 2.4GHz and 5GHz Wi-Fi frequencies.
The phone is loud -- both when playing music and during alerts or calls. There is a 2W speaker, which is rather good. The bass is a little tinny -- but the onboard loudspeaker is really good across the ranges.
The S86 Pro has a couple of extra features worth mentioning. The intelligent assistance feature lets you flip the phone to silence an incoming call, answer an incoming call by putting the phone close to your ear, and configure the phone to limit operation due to it sliding around in your pocket -- the 'anti-fake touch mode'.
You can also activate split-screen mode using a three-finger swipe, calibrate the proximity sensor and horizontal calibration modes and lift the camera to wake it. Other settings let you configure apps to run in the background.
Like most Doogee models, the outdoor toolbox icon has features such as a flashlight, height meter, protractor, plumb bob a sound meter, and an incredibly loud alarm.
There is one challenge with the Doogee S96 Pro if you are in the US. The unlocked version of the phone does not support some CDMA carriers such as Sprint, Xfinity, Verizon, and Trac Fone. You need to check with your carrier before you order the S86 Pro.
All in all, the Doogee S96 Pro is a fully-featured rugged, waterproof phone with a long-lasting battery and some nice extra features like a temperature sensor.
Pleasant to hold in hand, its large battery will last you for several days before you need to charge it, and its 2W loudspeaker means that you will not have to carry around an extra Bluetooth speaker with you.
For under $270, the Doogee S86 Pro rugged phone is definitely a good buy.

As expected the V10 is IP68, IP69-K and MIL-STD-810G rated; one can therefore guess that the design will follow a certain pathway. An industrial finish that mixes plastic, rubber and metal to make it more robust and protect the more fragile components.
The front of the device is occupied by a 6.39-inch HD+ screen covered with Corning Gorilla Glass and what looks like an oleophobic layer that mitigates smudges. The top left of the screen contains a pinhole 16-megapixel camera sensor, courtesy of Samsung.

At the back are four sensors arranged on a raised octagonal island, in a 2x2 matrix and consisting of a 48-megapixel main camera, an 8-megapixel wide angle camera, a 2-megapixel portrait camera - all Samsung sourced - and an infrared thermometer.

The right hand side of the device houses a fingerprint scanner, the power button and a volume rocker. The opposite side contains the dual SIM tray as well as a customizable button. The Type-C USB port is covered with a flap and there’s no 3.5-inch headphone jack.

A word on the dimensions of the beast; the size of the display and the capacity of its battery means that this was never going to be a small smartphone. At 199 x 184 x 37mm for a weight of 340g, it is a chunky bit of technology.
(Image credit: Future)
The Doogee V10 comes with the following hardware:
CPU: Mediatek Dimensity 700
GPU: Arm Mali-G57
Screen size: 6.39-inch
Resolution: 1560 x 720
Dimensions: 199 x 84 x37mm
Rear camera: 48MP, 8MP, 2MP
Front camera: 16MP
OS: Android 11
The Doogee V10 comes with the standard hardware you’d expect from a rugged smartphone within that price bracket. There’s a Mediatek Dimensity 700 system-on-chip with 8GB of LPDDR4 memory and 128GB onboard storage (using the more recent UFS 2.2 technology). Sadly, you can’t upgrade the onboard storage using a microSD card.
At 8,500mAh, the onboard battery is far larger than what we usually encounter in this price range and the presence of a 33W fast charger and a 10W wireless charging put the V10 squarely in the “very good” category when it comes to power. Doogee claims that the battery can be charged in less than an hour using the fast charger, something we haven’t tested.
No surprises when it comes to connectivity. There’s Wi-Fi 5, Bluetooth 5.2, NFC and an FM radio. Other than the 33W charger and the USB cable, there’s a sling cord and two screen protectors.

Performance and in use
The V10 can easily be used with one hand but just bear in mind that it is heavy. The features and apps that are worth noting are the system manager, a child mode and a game mode but no simplified mode for elderly users. And to complement the lot, an ubiquitous tool bag that contains a number of virtual tools aimed at those working out in the field.
This is how the Doogee V10 performed in our suite of benchmark tests:
PCMark (Work 2.0): 8398
Passmark CPU: 3205
Androbench (sequential): 1005 (sequential read); 511 (sequential write)
Androbench (random): 243 (random read); 244 (random write)
3DMark Wild Life Vulkan: 1111
LinPack MFLOPS: 733
The low screen resolution (1560 x 720 pixels) should improve battery life and reduce the strain on the GPU when dealing with resource hungry tasks. The thermometer app is intuitive and can measure temperatures of both people and objects and seems to be smart enough to differentiate between the two.
The V10 subsystem is supercharged, scoring some of the highest storage numbers we’ve seen in recent times including breaking Androbench’s sustained read speeds with a score of 1GBps. While that will not improve gaming performance which remains average at best, it does enhance the overall user experience.
Overall, it was one of the better Mediatek-based rugged smartphones we’ve tested, scoring above average numbers in most benchmarks.
Should I buy the Doogee V10?
Buy it if:
You want an affordable 5G with a big battery rugged smartphone
There’s plenty of reasons why you’d want to have a rugged smartphone with a big battery and 5G connectivity. Being able to use it as an outdoor mobile hotspot comes to mind, a particularly enticing proposition especially as it can be weatherproofed thanks to its wireless charging capabilities.

A smart thermometer with a long battery life is a must have
While the WP13 matches the V10 (including the thermometer), it doesn’t offer wireless charging and its battery is significantly smaller. However the 13% premium or the much bigger battery might be enough to sway undecided consumers either way.
Don’t buy it if:
Rock solid aftersale support is essential
Chinese smartphone vendors with no local presence can be a bit of a pain should you hit a snag. The lack of commitment to firmware updates as well can be a major downside if businesses are considering buying these products. Bear in mind though that only a few rugged smartphone vendors offer the level of support expected from the likes of Samsung or Xiaomi.
