It’s a funny thing, the tough smartphone.

See, what most people want is a slim, pretty device with just enough toughness that it’ll bounce, rather than break, when things go sideways.

What do you do, though, if you want something a whole lot tougher - and don’t care for the svelte smartphones clutched by commuters everywhere? Something that’ll happily hit rocks, plunge into icy streams and bathe in a sandy blizzard - and live to tell the tale?

Well, you could take a cheap Android phone, stick it in a hard-as-nails case and hope for the best. Or, you could spend €550 (RM2610) on the highly specialist - and ridiculously tough - Trekker-X3 from Crosscall.

Why would you do the latter? Because, far more than a wrapped-up mobile, it’s got the sort of features to keep mountain-climbers, off-piste skiers and gorge-walkers on track - and get them home again.

So, with that in mind, we took the Trekker-X3 to the launch of the 2017 Freeride World Tour in Chamonix, France, to put it to the test.

Crosscall Trekker-X3 review: Body, build and toughness

Pick up the X3 and its tough credentials will hit you like a punch to the gut from an angry polar bear. This thing is hefty.

With a 5in screen it was always going to err on phablet territory, but there’s nothing slim or light about the X3: at 14.3mm thick, it’s roughly as deep as two stacked iPhones and - coming from a OnePlus 3T - its 230g weight feels properly solid.

It’s no ugly lump, though. A textured back, rubberised shell and red highlights give it a surprising dose of style for something so solid, while metal bumpers on either edge offer more than a hint of premium kit. It’s sort of like a really good pickaxe: it’s specialist, but you can appreciate the craftsmanship.

And that build quality means it’s seriously rugged, too. It’ll take a dunk in 1m of liquid - whether chlorinated, salty or oily - as well as fending off dust, dirt and drops. Oh, and it’ll work all the way down to -10°C.

Yes, it won’t slip into your trouser pocket - but it will get a lot of attention down the pub. Especially as you drop it in your pint to prove that it’s waterproof.

Crosscall Trekker-X3 review: Sensors and usability

So it’ll take a hard knock. But many a rugged mobile has faltered in the past when it comes to usability? Thankfully, that’s very much not the case with the Trekker-X3.

Everything has been designed with tricky situations in mind. There’s no fingerprint sensor - that would mean taking your ski gloves off - but the screen itself is highly sensitive. So much so, in fact, that it can be used when wet and with thick gloves on - and it works.

Yes, it requires a bit of fumbling, but it means mountain-top texting without freezing paws.

That little red button on the side is useful, too: it’s a customisable input that can do things such as launch the camera or turn on the torch. It is a little too easy to press, which can result in unexpected pocket shots, but it’s the sort of clever touch that makes the Trekker-X3 stand out.

Crosscall has also stuck a suite of sensors into the X3 for those who don’t trust the internet. Don’t want to ask Google for the temperature? Take your own reading, using the in-built thermometer. Then measure the humidity. Then the altitude.

Why you’d need that data is another question, the answer to which probably requires technical, outdoors-y clothing and an immunity to low-oxygen nausea. Still, the sensors are accurate and add yet another string to the X3’s go-anywhere bow.

Waterproof wonder

Crosscall Trekker-X3 review: Camera

Less convincing is the X3’s camera. According to Crosscall, the aim was to make a fast lens which - while not delivering shots to rival the Samsung Galaxy S7’s - would do plenty well enough in active environments.

Sadly, it falls short of even that relatively low bar. Sure, it’ll take shots good enough to share online and, in good, bright conditions its snaps are just about convincing enough to plaster over Facebook.

In any other conditions, though, its 16MP rear shooter struggles with low-light grain - not to mention a sluggish camera app that gets easily confused when you rotate from portrait to landscape.

On automatic settings, images tend to lack soul, with washed-out colours. What’s more, despite that fast lens, motion blur is relatively common, even in static environments. There’s a general lack of sharpness, too.

And that’s a real shame, because it’s the one thing that really lets the X3 down. Most people who decide to buy Crosscall’s latest flagship won’t be expecting high-end glass - but they’d probably like their Mont Blanc holiday pictures to be bright, clear and sharp enough to share online, and that’s not something that’s guaranteed.
