CAT S31 in our hands, possibly the most resistant smartphone in the world [REVIEW]

They come to Actualidad Gadget Once again the analyzes of the most interesting devices on the market, today we have a quite special product, designed for those users who for professional reasons need much more than a phone, they need a work tool that meets their needs. The popular industrial machinery firm CAT has decided to launch an "indestructible" terminal on the market.

We have in our hands the CAT S31, a terminal designed to withstand the most extreme work sessions and that could become your perfect ally in situations where a normal telephone does not handle easily. Stay with us and discover the most interesting features of this device.

As always, we are going to differentiate the different sections where this CAT S31 highlights, to look at them in detail and tell you what our impressions are about these crucial points, take advantage of our index if you want to go directly to the points of your interest.

The hardware, adjusting the price with enough

At CAT S31 we find a mid / low range processor, manufactured by Qualcomm, de quad-core and capable of 1,3 GHz, enough, for a phone of these characteristics or for this purpose, but it is certainly not if what we want is to become habitual multimedia users. Memory level RAM and total storage we will have on the one hand 2 GB, enough for a mid-range terminal and to run the most popular applications from the PlayStore, and on storage we have 16 GB, something fair to store content but that we can logically expand through cards microSD, so in principle we are not facing a limited terminal.

The cameras are also designed to do us the service, an 8 Mpx rear camera, and a front camera for "selfies" if at work you want to post something on Instagram, you will have 2 MPx, so you won't be able to do too many flourishes. Continuing with the graphic section we go to the front panel, we have a 4,7-inch screen at HD resolution (720p) which in our test has shown sufficient brightness, although the resolution is not a boast, it should meet expectations within the functional framework for which it is intended. Last we have the battery, a section that could be quite decisive and where CAT has not wanted to skimp, 4.000 mAh that have allowed us to enjoy almost two days of autonomy with standard use.

  • Screen 4.7 ”HD touch screen with 720p (HD) resolution optimized for outdoor use even with wet or gloved fingers
  • Battery 4000 mAh
  • IP68 certification, protection from falls up to 1,8 meters to concrete, with MIL SPEC 810G military standard certification and Gorilla Glass 3 glass
  • Submersible to 1,2 meters for 35 minutes
  • Operating System: Android 7.1 Nougat
  • Conference proceedings RAM: 2 GB
  • 16 GB storage expandable via microSD cards
  • Processor: Qualcomm Snapdragon Quad-Core 1,3GHz
  • 8MP rear camera and c2MP front camera
  • Connectivity: LTE Cat 4, VoLTE, VoWiFi
  • Data connection: Dual SIM - Nano

The design is not intended to be pretty but functional

The terminal has a very clear orientation, it is designed to accompany you in your arduous work days, wherever CAT industrial machinery may be present. For it, on the front we will find the three Android interaction buttons with a traditional mechanical system, This will prevent them from breaking easily and failing in times of greatest need. The frames, as expected from a terminal like this, are quite generous, and we find the brand's silkscreen on the front left of the terminal.

On the sides we will find the keypad, fully integrated into its rough, easy-grip material that will allow you to cope in the most extreme situations. The connections are properly sealed with rubber caps, in the upper part the audio jack, in the lower part the micro USB (it would not have cost anything to add the USB-C cable at this point) and on the left side the card covers. memory and telephony. It is quite clear that we will not have the most beautiful phone in the neighborhood, but we will have the most functional. In our tests it has been quite comfortable in the hand, easy to use from many positions, It is clear that it is big, but it is designed precisely for that.

Military resistance so that breaking it is not your main concern

What is this terminal capable of withstanding? In our tests, we have seen fit to wet it in puddles, which has not shown the slightest of problems. Similarly, we have tested drops from about a meter high in various positions, and the phone just bounces, in fact we have feared in some of the tests on the office floor. In short, everything you can expect from IP68 certification, it is thus resistant to water, dust and falls from 1,8m on concrete. Thanks to that has passed the military test with flying colors MILSPEC 810G for ultra resistant mobiles that guarantees the good functioning of the device in extreme environmental conditions.

We have safely tested all the features that this phone boasts, and it has passed them with flying colors. Perhaps we must bear in mind that at the hardware and multimedia performance level we do not have much less what we can find in the mid-range at similar prices. This is because in our hands we do not have a telephone, but a work tool.

For example, CAT has seen fit to include a series of applications within the operating system installed natively that can get us out of more than one trouble like measuring cameras or a level. Things that can easily get you out of trouble in work situations.

Pros

  • Certifications of resistance
  • Autonomy
  • Price
  • ?

Cons

  • More processor is missing
  • ?

However, it shows more than enough to run the most popular apps from the Google Play Store. The price is quite attractive, perhaps what is more, since We can get this CAT S31 on sale from 284,05 euros on Amazon.Ultimately, CAT delivers what it promises, and it is a good opportunity to enjoy a terminal of these characteristics, to you, a day-to-day professional.
