Reviews for the CAT S42

73% CAT S42 Smartphone Review – Robust, rubberised and washable smartphone | Notebookcheck
The predecessor model retailed for about 500 Euros ($590). However, the CAT S42 is twice as cheap. This is possible because CAT has cut production costs, especially when it comes to the display and the battery. Read our review to learn whether or not the robust, waterproof smartphone is worth it.
CAT S42 smartphone review
Source: Android Guys English
I only spent a few days with the CAT S42 as my primary device and I’ll admit that I was not only pleasantly surprised if not impressed with it. The phone does many things well. Especially when you consider the retail price is only $299. Battery life is its strongest attribute along with its physical durability. I didn’t purposely drop the phone but the CAT website boasts it will survive a six-foot drop on steel. I didn’t test its waterproof rating either. The IP68 rating indicates it will survive prolonged submersion in water beyond one meter.

70% The Cat S42 Is Exactly What A Rugged Smartphone Should Be
Source: Make Use Of English
Whether you should buy this phone is trickier than most other phones. If you're an independent contractor or own a construction or similar business, yes, this makes sense. If you work for someone else, the question shouldn't be whether you buy this phone but whether your company does.

Despite looking the part and being suitably robust, the S42 doesn’t sport the hardware to justify its price point. It’s short on memory, storage and video resolution. But the screen is decent quality, and the Cat applications are well designed.

80% Cat S42 review: an extra rugged phone for an affordable price
Source: T3 English
The Cat S42 just has two real selling points – the ability to withstand drops, heat, cold, water, dust and more besides; and how easy it is to clean. If those would be big benefits for you, then the Cat S42 is one of the cheapest and most appealing rugged phones currently on the market.

Device review: Cat S42 – low specs, high durability
Source: What Mobile English
The S42 should find a home in many industries, especially at Cat’s cheapest launch price yet. While it’s missing the performance power of non-rugged phones in its price point, and the fancier abilities of pricier, more specialised rugged devices, it’s still a solid performer that you would have to try very hard to break. It’ll last through a day’s consistent user, and the camera is good enough to do the jobs it will need to do.

This display is quite big for a smartphone but frequently used for smartphones.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

This weight is typical for smartphones.


CAT, which can be easier found under CAT Phones in the web, gets seldom reviewed, does hardly have any market shares and achieves average ratings (as of 2016).
