Crosscall Trekker-X4 Smartphone Review

Florian Schmitt, 👁 Florian Schmitt (translated by Katherine Bodner), 03/05/2019

An outdoor companion. The Crosscall Trekker-X4 presents itself with images of people being outdoors, doing sports and simply enjoying life. With a large array of available accessories, the device is supposed to easily replace an expensive action camera. Find out in our review whether the phone keeps its promise in terms of stabilized videos, slow-motion features and editing software.

Crosscall Trekker-X4

Crosscall is a French smartphone manufacturer that specializes in devices for sports and outdoor activities. Its smartphones are waterproof and feature clever functions that are made to support outdoor lovers. The Trekker-X4, for example, is supposed to replace an action camera with its special camera functions. The manufacturer promises stabilized images, optional distortion-free wide-angle shots and good video quality. The device has a very special design and supports the X-Link magnet connector with which you can connect numerous specialized accessories. And of course, the smartphone is waterproof and dust protected. We shall be testing this in our review. 

We have decided to compare the device, which is available in the UK for around £600 (roughly $800), with the more affordable Action-X3 (another Crosscall smartphone) and other high-quality outdoor smartphones such as the CAT S61 and the Land Rover Explore. Alternatively, might a more affordable device such as the Ulefone Armor 6 do the job as well?

Case – lightweight outdoor smartphone

If you are interested in Crosscall, you will probably have at least seen a picture of their devices. Moreover, you might have noticed that Crosscall has a rather individual design language. The classic black of the device might sound very normal - the asymmetrical shape of its silver earpiece at the top of the device and the tear-shaped camera module on the back with an asymmetrical flash, however, make quite a statement in terms of design. The back of the device also depicts the shiny silver logo and, beneath that, features the circular X-Link magnet connector, which we will talk about in more detail later on.    

Despite all these design features, the Crosscall Trekker-X4 actually seems rather inconspicuous compared to other outdoor phones. It should therefore also be quite suitable for the business environment - unless, perhaps, you are about to walk into a board meeting. But the outdoor phone can also be an advantage if you have on-site meetings at a building site or in other dusty or damp environments, for example, as the device has an IP68 water and dust protection - provided the flaps over the USB port and 3.5-mm audio jack are closed. Crosscall has also done extensive tests and claims that the device survived the MIL STD 810G test (dropping the device from 2 meters/~6.6 feet).

The smartphone appears stable and compact and has discreet aluminum reinforcements on either side. The Crosscall phone handles pressure very well - only the bottom right area of the screen produced some noises when we put pressure on the screen. The classic 16:9 layout and the relatively wide display bezels make the Trekker-X4 rather unsuitable for small hands. The outdoor device compensates its large dimensions with a relatively low weight of 232 grams (~8.2 oz).

Connectivity – a lot of sensors

The device comes with 64 GB of storage and 4 GB of RAM. This is quite decent for an outdoor smartphone of this price range. However, the Ulefone Armor 6 shows that you can get 128 GB in an outdoor case for a lot less money. The manufacturer claims that you can add up to 512 GB via microSD - however this comes at the price of one of the two SIM slots.

The Crosscall Trekker-X4 positions itself as an upper mid-range device in terms of its performance components. Normally, this would be too low for a device of this price range, but of course the outdoor capabilities of the phone do not come for free and both the CAT S61 and the Land Rover Explore cost a similar amount while offering the same performance level.

The Trekker-X4 offers many sensors - for example a UV sensor and a barometer. Its USB-C port also supports USB 3 speeds. The device does not support DRM Widevine L1, which means that HD content from streaming services cannot be streamed from this phone.

Software – app combines all sensor measurements

The Trekker-X4 runs on Stock Android 8.1 with the security patches dating January 2019 at the time of testing, which is still relatively up-to-date.

The most noteworthy software addition is the photo and video application X-Cam, which combines the various recording modes and offers a basic editing tool (X-Story). We will go into further detail on the different modes available and how well the app works in our camera section. Another gimmick is the Sensor hub, which offers a summary of all the values measured by the individual sensors - and there are a lot: Thermometer, UV sensor, barometer, altimeter, hygrometer (to measure the humidity in the air) and all the usual sensors.

Communication & GPS – decent positioning

All current Wi-Fi standards are supported by the Trekker-X4. Our Wi-Fi test with the reference router Linksys EA8500 shows that the Crosscall Trekker-X4 has the transfer rates of a mid-range smartphone. The other outdoor phones in our comparison have similar results. 

The device is also well set up in terms of LTE frequencies. Users should therefore always find a suitable LTE network even when traveling further abroad. We tested LTE reception in an urban area and encountered no issues.

Of course GPS functionality is very important for an outdoor smartphone. And it lives up to its name: It did not manage to find a GPS signal indoors, but found one quickly and quite accurately within 3 meters (~9.8 feet) outdoors.

Our practical test - a bike tour together with the professional navigation system Garmin Edge 520 - shows that the Trekker-X4 GPS tracks us quite decently, although the professional navigation system makes fewer shortcuts and follows us a little more precisely. So do not expect complete accuracy - but if your expectations are not too high, you should be perfectly happy with the Trekker-X4's navigation.

Telephone & Voice Quality– no VoLTE

Crosscall has made no changes to Google's standard telephone app.

The voice quality in our test is mixed: While the earpiece transmits voices quite loudly, the audio could be clearer and there is an audible drone at high volume. The internal microphone did a pretty good job at transmitting our voice to our call partner - even when speaking quietly. We also heard our call partner loudly on speakerphone, albeit the voice sounding slightly muffled. Again, our voice was transmitted clearly.

The Crosscall Trekker-X4 does not support VoLTE and VoWiFi.

Cameras – ambitions to be an action camera

The manufacturer has paid close attention to our test unit's camera module and this might be one of the most important reasons for purchasing the Trekker-X4: Crosscall promises a smartphone that can replace an action camera, for example, from GoPro or Sony.  

The manufacturer has installed a fisheye lens and a telephoto lens on the back of the device, and equipped these with an optical image stabilizer with six axes. Suitable software is included as well.

With a resolution of 12 MP, the smartphone positions itself on the same level as GoPro's current flagship model HERO7 Black. However, the Trekker-X4 is more limited in its video capabilities: While you can make 4K recordings, these are limited to 30 fps. Slow-motion videos can be recorded five times slower with 120 fps in Full-HD. The HERO7 Black offers 8x slow motion. Users can choose between five perspectives: The normal view through the telephoto lens, a slightly wider view with hardly any distortions, and Super and Ultra Large, both of which show significant distortions even in the image center due to the fisheye lens, and finally the fisheye perspective that offers a 170° angle. 

The telephoto lens and fisheye images are not stabilized; the electronic image stabilizer is active in all other perspectives and is supposed to stabilize the image via gyroscope data. Small shakes are compensated for quite well, but stronger movements - that do often occur when doing action sports - make the image edges visibly shaky. We are quite happy with the video quality - particularly with the fact that the result remains the same whether the device is in portrait or landscape mode.

If you would not have invested in one of the more expensive action cameras available anyway, you should be perfectly happy with the Crosscall Trekker-X4's capabilities. Real professionals might still prefer dedicated devices.

Photos taken with the main cameras often appear slightly washed out close up and pictures taken in dark surroundings lack brightness. Overall, the image quality is average. The 8-MP front camera also takes decent photos with relatively good dynamics, although there can be severe image noise in dark areas.

Accessories & Warranty – a lot of accessories

It will be hard for other manufacturers to keep up with Crosscall in terms of accessories. For one, our test unit offers an X-Link magnet port on the back, which allows you to connect numerous accessories. The included X-Blocker additionally stabilizes the smartphone when placed in mounts. The included quick-charge power supply looks good and recharges the device quickly thanks to QuickCharge 3.0.

Crosscall also offers a large array of accessories that can be purchased separately: For example, X-Chest is a fixing harness, which allows users hands-free action videos. Other available accessories include a selfie stick with a tripod, a microSD card reader, power banks with and without solar panels, a mount system for your arm, bike or car and a docking station.

The manufacturer includes a 24-month warranty. This apparently includes the water- and dust-resistance of the device.

Input Devices & Handling – glove mode

The touchscreen of our test unit responds quickly and reliably to input, even at the edges and in the corners. The Crosscall Trekker-X4 also offers a glove mode for the touchscreen. When this is activated, it really is possible to use the phone while wearing thick gloves. 

The manufacturer has gone with Google's GBoard as the default virtual keyboard. This enables reliable typing while giving users a lot of customization options. Other keyboards can easily be installed as well. Should you wish to download a different keyboard, please make sure you choose a trustworthy provider: In theory, a keyboard app could record all your inputs - including passwords.

The fingerprint reader is integrated into the standby button on the right side of the case. It is activated by pressing the button and unlocks the smartphone reliably and without delay. The Trekker-X4 has its own camera button as well as two buttons for volume on the left side of the device. They are all easy to use and have a good pressure point.

Display – not that bright

Subpixel array
Subpixel array

If you do not need the modern bells and whistles such as a notch or unusual display formats, you should be quite happy with the Crosscall Trekker-X4: It offers a classic 16:9 screen. This also means that most videos can be displayed without black edges in full-screen mode.

The screen resolution is 1920 x 1080 pixels - this is sufficient, but does mean that users cannot display the 4K videos recorded by the camera in full quality. 

The brightness of the display is specified as 450 cd/m². We cannot confirm this after our tests: We measured a maximum brightness of 378 cd/m². We previously noticed that the manufacturer does not seem to take screen brightness too seriously during our review of the Crosscall Action-X3. Other outdoor smartphones such as the CAT S61, on the other hand, make a point of offering good screen brightness. Overall, it makes sense to have a bright display, since users will want to read screen content even in bright surroundings. This is a weakness of the Trekker-X4, unfortunately. The brightness distribution is only mediocre as well at 86%.

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 detected 2315 Hz ≤ 20 % brightness setting

The display backlight flickers at 2315 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2315 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9418 (minimum: 43 - maximum: 142900) Hz was measured.

The black value of the screen is decent at 0.35 cd/m², which means that the contrast is quite good at 1069:1.

Our screen test with the spectrophotometer and the CalMAN software revealed quite a strong blue cast that is accompanied by a very high color temperature of 10554:1. According to our color space test, which should be seen more as an indication, the smartphone covers the entire sRGB color space.

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

Performance – fast outdoor phone

The Crosscall phone comes with a Snapdragon 660 - a fast upper mid-range SoC. This places it above all of its comparison devices - particularly the CAT S61 and the Land Rover Explore turn out to be slower smartphones despite their similar price. The device should offer sufficient power for more demanding apps and we encountered no lags or long waiting periods during testing. 

The Adreno 512 is responsible for graphics and works quite quickly as well. Only the Ulefone Armor 6 can more or less keep up with our test unit.

* ... smaller is better

Crosscall has chosen a relatively slow eMMC flash storage for its Trekker-X4. However, the other smartphones in our comparison can hardly offer better transfer rates, so the Crosscall is on par with its competition.

The microSD card reader offers average speeds according to our test with the reference microSD card Toshiba Exceria Pro M501.

Temperature

The temperature development of the case is not noticeable when the device is turned on but not under load. Only in the bottom center of the phone in portrait mode did we notice a very light temperature rise. However, the device heats up to 49.4 °C (~121 °F) in certain areas under continuous load - this is very warm and touching the smartphone directly on those areas or putting it in your pocket after working under load is rather uncomfortable.

Speakers

Pink Noise speaker test
Pink Noise speaker test

The Crosscall Trekker-X4 has stereo speakers positioned on its back. This is a little confusing since it would encourage users to flip the smartphone in order to get the best sound. This, however, switches the position of the speakers, so that the left speaker is on the right side and the right on the left, and means that the stereo signals are output the wrong way around.

Overall, the sound is decent and can be quite loud. Music sounds acceptable, although there are some uncomfortable frequencies when playing orchestra sounds, for example. This is also because, like in almost all smartphone speakers, the upper mids and highs are strongest.

Users can also output music via the 3.5-mm audio jack or Bluetooth 5.0. Both transmit sound clearly.

Battery Runtime

The 4440-mAh battery in the Crosscall Trekker-X4 is rather large. However, the runtime is very similar to that of the Crosscall Action-X3, which is equipped with a much smaller battery. Our test unit managed a runtime of around 14 hours in our Wi-Fi test, which is a very decent result and should easily last two working days or a long tour.

The included power supply supports QuickCharge 3.0 and fully recharges our test unit in around 2 hours.

Verdict – can sometimes replace the action camera

Review: Crosscall Trekker-X4. Test unit provided by Crosscall Germany.
Review: Crosscall Trekker-X4. Test unit provided by Crosscall Germany.

Crosscal has found its niche and fills it out nicely: The Trekker-X4 offers a lot of functions that users would expect from an outdoor smartphone for active people: Long battery runtimes that make sure you don't run out of battery on a long day, high performance - enabling the use of GPS apps together with other applications - and many LTE bands to connect to the mobile Internet even when travelling. 

But can the smartphone really replace an action camera? While it will not fulfill the highest expectations - the camera is limited to 1080p and 30 fps, which is a shame when recording fast movements - the fish-eye lens and normal camera with a decent image stabilizer will allow leisure users to occasionally leave the GoPro at home. The wide array of accessories that is available for the Trekker-X4 makes this function even more attractive: The phone can record action videos while strapped to a chest harness or a bike.

Many accessories, high performance, and long battery life: The Crosscall Trekker-X4 is a reliable leisure companion and can even occasionally replace an action camera.

The manufacturer could have chosen a brighter screen and more precise GPS functionality might also have been worth the investment for an outdoor phone. However, the many sensors and good overall package make the Crosscall Trekker-X4 a good leisure companion nonetheless.
