Build quality & Display

For rugged smartphones logically it is very important to have a great build quality because mostly they need to be water resistant, but of course they are also resistant to dust and other possible problems. Also they are mostly used in difficult conditions. So from what we can see Nomu S20 is offering great build quality because the case has military-grade body, or in other words it is shatter-resistant up to 1.5m.

So if you drop the phone from that height it will not happen anything to him. Also the case is made from rubber, and it is a little rough under his arm, so you can not drop it easily out of hand. Likewise all ports are protected with lids, the water nor dust can not enter. But when we talk about the screen then we can tell you that the screen is protected with Corning Gorilla Glass 4 protection which is offering very good protection for the screen. Anyway the screen size is 5 inch with HD resolution which is offering good screen combination. From every angle screen is offering good visibility including sharpness and colors.

What is the standard IP68

International Electrotechnical Commission measures the degree of protection casing, or “IP Code”. IP68 means that the unit must be completely impermeable to dust and water to a maximum depth of 1.5 m for 30 minutes.

As title says Nomu S20 has IP68 rating, so the entire rugged device is completely impervious to water and dust. Besides that it can work on working temperature from -20 degrees up to approximately 55 degrees. So overall they did a great job because Nomu S20 high build quality, and at the same time it looks really cool. Also the phone size is not too much bigger than usual smartphone which is actually great because we all know that rugged smartphones are often bigger.

Performance and benchmark testing

But this is not all people because this rugged smartphone has also really good built-in hardware. It is based on 64 bit quad core CPU Mediatek MT6737T with maximum speed 1.5GHz. When we talk about memory it has 3GB of RAM made by Samsung including 32 GB of storage space. But if this is not enough for you then you can upgrade using the microSD card up to 32 GB.

Camera Quality

The rear camera is 8 megapixel which has Sony IMX219 sensor, also in camera application photo resolution can be set as 13 megapixel thanks to interpolation. Mostly camera is not the primary feature of any rugged smartphones but lately the vision of rugged devices is changed.

So today almost any device including Nomu is improved on almost any field. We have been very curious what kind of photo quality is here. Because of that we have taken photos in every different condition and location, and below you can see photo samples. But overall it is offering good quality especially for this price range which is around $150.

    I noticed you made a mistake calculating the battery capacity. Your testing device showing 2.1 Ah at 5 volts which gives us 10,6 Wh. Divide 10,6 Wh with 3,7 volt (nominal voltage of a li-ion cell) and it gives us almost 2900 mAh. Of course, this also include some losses in the step-down conversion, but these are normally fairly small.

    Bought two S20s, one for me and one for my Mum, unfortunately, while mine has been great, hers developed a screen fault before she even took possession of it (I was setting it up for her, I turned it on when it first arrived and all was good, then turned it off and put it in the box, waiting for the nano SIM to arrive. Powering it up next time showed the fault, with or without the SIM, so it basically developed a fault sitting in a box).

    It’s currently waiting to be RMAed to gearbest. Had a quick look and didn’t find anyone having similar probs (the phone is working, but the screen is a series of horizontal lines, so seems to be an LCD driver fault), so maybe a one-off, but I doubt it.

    good review, good features but price is very high.there are many rugged smartphones with good look and high spec like AGM A8. AGM A8 cheap, strong GPS, Android 7.0 Out of Box, you can run Lineage OS 14.1 + Resurrection Remix OS, 13MP camera, fastest processor, and for more Check the video and find how?

    Guys I recommend you AGM A8 because it is decent budget rugged smartphone in the market. AGM A8 much better than others in term of strongest GPS, great design, camera quality, NFC, battery life, and others. AGM is testing features and updating Operating system regularly. I updated my device to Android 7.1.1 and intalled lastes Lineage OS 14.1. if you compare AGM A8 with Nomu S20 you will find AGM A8 much better than Nomu S20 in term of Camera, OS, Battery capacity and quality.

    Cool phone Nomu is doing a great try … but in that range : AMG to me is way more appealing (does promises strength and performance as a “regular competitive smartphone” … to launch the first rugged dual camera and resistance to everything) … Still, i love that both ( AMG and Bv) are really defying their style and not imitating Samsung 😀 AND NOW WE HAVE THE X1 GOLD 18K Edition :O !!

    why should i get Nomu S20 ?
    on the same price i can get better IP68 smartphone. AGM A8 come with Android Nougat and updated lastest 7.1.1. if you compare AGM A8 with Nomu S20 you will find AGM A8 much better than Nomu S20 in term of Camera, OS, Battery capacity and quality. Nomu S20 not support NFC.

    check gretel S5 video, the Gretel S55 smartphone is put through a number of stringent tests including the scratch test, fire test and more. Will the S55 shine in all these examinations?

    There is a time i find fast charge is really important. Because of the delay of the airplane, my phone runs out of battery and i find a place to charge in the waiting hall. after 1 hours the electricity is enough for me to go through the whole flying time and contact the receiver of hotel. I just can’t imagine what will happen if my phone didn’t work. I am glad to see that the S50pro has big battery and fast charge.
