Getting started with the Crosscall Trekker X4: the unbreakable wants to become a photographer


The Trekker-X4 is the latest rugged smartphone from Croscall. We were able to take it in hand and take some pictures of this camera supposed to withstand all the tests.

When you drop your phone, you're always in a more or less intense doubt: is the device broken, or has it remained intact? Fans of quantum physics and Schrödinger's cat will tell you that they are both at the same time until you pick it up.
One of the missions assigned to the French brand Crosscall takes root in this issue. The latter wants to get rid of this kind of concerns by offering resistant smartphones. We were able to take control of his newborn, the Crosscall Trekker-X4.
Design
Right out of the box, the Trekker-X4 gives off a real impression of robustness with its thick, imposing format and aggressive lines. By turning on the screen, we realize that the display area is far from covering the entire front panel. The black outlines are therefore particularly marked. However, it is difficult to hold him to this type of detail. Before being beautiful, the smartphone wants to be strong. Efforts will be made to set aside certain requirements. Simply note that the grip, the weight above 250 grams is felt well as the massive character.
The bottom border is useless, occupied only by the logo of the mark. On the front, the call speaker stands out very well with its metallic gray color. It has a twisted trapezoid shape and reminded me of the comma of the Nike logo. Just a little. He is accompanied on his left by the front camera.

It should be noted that the entire Trekker-X4 is made of a reinforced plastic to absorb shocks. On the left and right edges, there are metal plates screwed. The back of the smartphone is quite special. On the one hand, the side parts have been worked to facilitate apprehension and are therefore not smooth unlike the rest of the back surface.
On the other hand, there are a lot of elements that jump to the eye. The photo module is particularly imposing. Everyone will not necessarily appreciate, but personally I found the aesthetic bias interesting. The ultra-wide-angle lens (170 degrees) can be easily seen under the wide glass plate Gorilla Glass 5. The second, more discreet lens fits just below the flash and autofocus.

C Crosscall is once again affixed to this part of the smartphone, in the middle. And finally, we can not miss it, a magnetic connector, round, was integrated on the back of the Trekker-X4. This one allows to take advantage of several accessories of which here are some examples:
a charger with a suitable magnetic attachment
a harness to hang the phone around the bust
a three-foot pole with remote control
charging kit and fixing for the car
                  
To continue the tour of the owner, specify that the fingerprint reader is positioned on the right edge – as on the Samsung Galaxy A7 2018. It also serves as an unlock button. On the same side, there is the shortcut button for the camera, while the volume controls are placed on the left.
The USB-C port (bottom) and the jack (top) are protected by a cover. The Croscall Trekker-X4 can ship two nano SIM or a nano SIM and a microSD. The device is IP68 certified and therefore waterproof. Finally, the two speaker grilles are at the back.
For the purpose of this paper, I threw the phone down on the ground several times and I also plunged it into the water without noticing the slightest after-effects of this abuse. For the more cautious, a small hole in the corner allows to fix a clip to carry around the shot.

Difficult to make a complete judgment of the IPS screen except that it is in contradiction of most of the slabs that one currently crosses on the market. It has indeed a diagonal of 4.79 inches for a 16: 9 ratio. The definition of 1920 x 1080 pixels is largely sufficient to ensure a good reading comfort (the resolution is 401 pixels per inch). The glass used is Gorilla Glass 5 certified.
Software
The Crosscall Trekker-X4 runs on Android 8.1 Oreo with some applications preinstalled by the manufacturer. We will retain two essentially. The first, X4-Sensors, provides access to all embedded sensors to gain a better understanding of its environment. The service indicates temperature, humidity level, atmospheric pressure or even UV exposure.
For all other more conventional sensors (GPS, accelerometer, proximity …), the application is more to ensure that they work properly in case of doubt. For example, for the proximity sensor, a red dot turns on and off depending on the obstacles in front of it. As a result, if it does not come alive, the user will know that this feature is down. It's handy to self-diagnose your phone.

Crosscall also highlights the X-Cam application. The classic camera can already switch from normal shooting mode to a fish-eye or lock the touch screen to take pictures underwater. X-Cam goes a step further and proposes to vary the shots between 88, 110, 140 and 170 degrees (normal, wide, super wide and ultra wide). The fish-eye effect is still available from this app too.
                    
X-Cam also integrates a social network dimension by proposing to make "X-Stories" or to record live videos by broadcasting them on Facebook. Moreover, as far as photography is concerned, both sensors benefit from a definition of 12 megapixels. At first glance, the quality of the shots does not seem particularly incredible, without being really bad either. We are in the middle of the "meh".

It is possible to shoot in 1080p recording up to 120 frames per second and enjoy a stabilization on 6 axes which can be convenient for extreme sports.
Performance and battery
The Trekker-X4 ships a Snapdragon 660 with 4 GB of RAM. The storage space is 64 GB. So we are on a technical sheet similar to what is usually found in the mid-range segment on conventional smartphones. With the battery of 4400 mAh, the autonomy should not be a big problem on this device.
Note that it comes with a cable braided and robust – which we particularly appreciated – which combines a load of 24W for fast charging. The Trekker-X4 is compatible with all French 4G frequency bands, but also with Bluetooth 5.
Price and availability
The Crosscall Trekker-X4 costs 699.90 euros (recommended price). It will be up to everyone to estimate whether this rate is justified in view of the proposed experience. Everything depends on the uses.
For all accessories, we invite you to go look at the prices on the manufacturer's website.
