Description of the Cat S31 Dual SIM Black

Detailed description of the Cat S31 Dual Sim Black

On 31 August 2017, Cat presented the S31 as their successor of the S30. The Cat S31 comes fitted with improved specifications but still has a very rugged and robust casing. On top of that, this phone is dust and water-resistant.

The S31 has a 5-inch display, which makes it slightly larger than its predecessor. This screen has a resolution of 1280x720 pixels, which makes it a good and clearly legible screen. Under the hood, the device features a good MediaTek processor and 2GB of RAM, which means that it can runs most apps smoothly.

IP68 and MIL-810G

If you're looking for a phone that can handle rugged terrains, the Cat S31 has got you covered. This device is fully dust and water-resistant, which is why it has an IP68 certification. Dust will not be able to penetrate this device and you won't have to worry about the S31 if you drop it in a puddle.

The casing is also very robust, which is why it has a MIL-810G certification. This means that the S31 can handle drops and wear and tear! With the Cat S31, you won't have to worry about your smartphone, wherever you're headed.

Handy cameras

The Cat 31 comes fitted with two handy cameras, which make it the perfect device to capture all your favourite moments. The main camera can take clear snapshots, and the front camera is perfect for taking selfies or making video calls.

Stunning display

Cat has fitted the S31 with a 5-inch display with a resolution of 1280x720. With this screen size, this phone can easily fit in your pocket but is large enough to get some work done. On top of that, the screen is large enough to enjoy a video.

Expandable memory

Out of the box, this phone has 16GB of internal memory. This gives you ample room for a number of apps, pictures, videos and other files. However, if you do run out of space, you'll be able to slide in a microSD card for extra storage space.

Android Nougat

The Cat S31 runs on Android 7 Nougat. With this user-friendly operating system, this device is very easy to use. The interface is very clear, and you'll get direct access to Google services including Maps and Drive. You'll also have access to the Play Store, where you download apps and games for your phone.
