Nomu S10 is the cheap outdoor smartphone of the new manufacturer. A quadcore processor, 2/16GB storage, an HD display and IP68 certificate are appropriate for a 100$ phone. In contrast to S20, the S10 has less storage, a worse camera and is also thicker and heavier. On the other hand, S10 has the more robust casing and with its 5,000mAh a much better battery. Even if the two phones are much alike on paper, the differences in practice are noticeable. I switched directly from S20 to S10 and tested it for seven days.

Versions and prices

Nomu S10, S20 and S30

Nomu S10 can be considered as good alternative to the S20. Nomu S30 has a 5.5-inch FHD display and a significantly faster processor. Thus, it plays in another league.

Design and build quality

As a standard outdoor phone, Nomu S10 is quite heavy with 220g and thick with 14mm. It is also longer and wider than its more expensive brother with respectively 145mm x 76mm. On the right side there is the power button and volume control which react quite nice but have to be pushed quite hardly. On all four edges you can find rubber bumper which protect the phone when falling to the ground. In case of a drop, the phone directly falls on the display as there are no protruding components. This is user-friendly, however, more risky compared to Blackview BV6000. Nomu S10 is excellently built and even survived ten minutes under water. It also took no damage from various drops.

The mobile does not feature a notification LED and via on-screen buttons you can navigate through the system. The entire casing consists of firm rubber which cannot be removed, meaning that you are not able to access the 5,000mAh battery. On the left side, you can decide whether you would like to use two SIM cards (1x nano + 1x micro), or one SIM and one micro-SD card (hybrid slot). Nomu S10 has a safe grip and appears robust. It leaves an outdoor suitable impression.

Micro-USB and headphone plug have rubber caps which protect them from incoming water. The device is available in black and black/orange. In this colour combination, the phone may look like a construction site machine, but to be honest, it looks quite cool. Nomu S10 feels of much higher-quality than the price suggests.


Display Display

Just like his two brothers, Nomu S10 houses a sharp and colourful display. The 5-inch panel has a resolution of 1,280 x 720 pixels which results in 294 pixels per inch. Viewing angles are stable and the brightness is sufficiently high, even in bright sunlight. The screen is protected by Gorilla Glass 4. Five touching points are registered simultaneously by Digitizer. Considered that this is a low budget outdoor phone, the touchscreen operates very precisely and processes inputs quickly. In the options menu, the display can be adjusted via MiraVision. Nomu S10 has a nice and exemplary IPS display.

This mobile is meant for standard tasks and thus inadequate for demanding 3D games. The quad-core processor is provided by Mediatek and clocks with 4x 1.5GHz. It is found in most of the low budget smartphones. Here, it is supported by 2GB RAM, half of which can be used for multitasking purposes. With a pace of 3GB/s, the RAM has exactly the same speed as S20. The 16GB internal storage and its reading/writing speed of 120/21MB/s, in contrast, is considerably slower. This becomes obvious when installing new apps. During casual usage it remains unnoticed. On S10, apps open quickly, system runs fluently and surfing is smooth. Temperature rising is not perceptible due to the thick rubber casing.

Operating system

Nomu S10 runs with an almost untouched Android 6 system. Apart from SmartWake features, a special screen-shot programme and the standard Google group (Gmail, Playstore, maps, etc.), it is also free of annoying spam apps or Bloatware. Updates are installed directly via OTA. With a low budget phone, there is no hope for Android 7. Nomu S10 is a great choice for everyone looking for a stable, fast and flawless stock Android system.


According to the manufacturer, Nomu S10 features the same 8 megapixel Sony IMX219 sensor as Nomu S20. In practice, however, there are significant differences in sharpness and amount of details in images. Producing acceptable sharp pictures with Nomu S10 is no simple exercise. Under favourable light conditions, images often turn out overexposed. Further, pictures only have acceptable sharpness in the center. A clear blurredness is noticeable on most of the pictures. Colour representation is identical to S20’s. Selfies are always blurry, just like it is the case with S20. Video telephoning is acceptable with the front camera. Selfie fans will not be satisfied with this mobile. A 100$ phone is no prodigy with flawless features all the way. Thus, a great camera is not featured. For occasional snapshots it might be enough but hobby photographers will not be satisfied. The partly poor image quality might be caused by a badly adjusted autofocus. This could be solved by an update.

Connectivity and communication

SIM slot

Nomu S10 supports the following 2G, 3G and 4G (LTE) frequencies:

2G: GSM 850/900/1800/1900MHz

3G: WCDMA 900/2100MHz

4G: FDD-LTE 800/900/1800/2100/2600MHz

TDD-LTE 2300MHz ( B40 )

No problems arise in the browser, during rendering or surfing. Calling quality is also convincing. You get a clear voice representation in high volume. The loudspeaker is usable, however, transmits any loud background noise.

The loudspeaker is located on the rear side and is very loud. Even louder than S20’s loudspeaker and due to its location on the back side, a spatial sound is produced. In total, the quality is on average and for a low budget phone it is perfectly fine. When connecting middle class headphones, you will receive nice sound but don’t expect extraordinary sound experience.

The Wi-Fi module operates with n-standard and only transmits in the 2.4GHz network. Transmission rates are high and reception reach unremarkably good. Its Bluetooth 4.0 module works reliably. Nomu S10 always connected automatically with the car. Navigation always took place without any problems in practice. Both, pedestrian and car navigation, was satisfying. The integrated compass had to be re-calibrated a few times which was quite disturbing for pedestrian navigation. Compared to S20, the S10 required considerably more time to connect to the same amount of satellites, if the same amount at all. The phone also houses an acceleration, proximity and brightness sensor.

Nomu S10 features a 5,000mAh battery. Together with the economic quad-core processor and ‘only’ a HD display, this results in excellent battery life. One hour of HD video streaming on YouTube only uses 8% battery in medium brightness. In the PC-Mark battery benchmark, the device endured 11 hours in a row, also in medium brightness setting. In standard use, the phone can easily reach 2-3 days without charging. Using the entire battery life in one day, even with extensive GPS usage, is hardly possible. Unfortunately, quick charge is not working and the time until it is fully charged again can last up to 4 hours.

Conclusion and alternative

Joscha Becking:

Cheap outdoor smartphones are popular and Nomu decided wisely to fill this gap. A Homtom HT20 or Ulefone Armor seem to be no competition for Nomu S10. It is a well-built device in a huge rubber casing with stylish orange lines. Standard functions are carried out flawlessly. Sophisticated tasks can be improved. Clear advantages are a good display with precise touchscreen and sufficient performance for standard tasks and games.

GPS reception is slightly weaker compared to its brothers but still on a high level. Battery life, in contrast, with 5,000mAh, is a highlight. The high-volume loudspeaker will be appreciated even in loud environments. As there are only 16GB internal storage, the hybrid slot with expandable storage or dual-SIM is quite annoying but bearable. Despite the fact that the camera sensor is allegedly the same as in S20, S10 produces worse images. You have to compromise with a 100$ phone, as always, but we can clearly recommend Nomu S10.

Battery life on my S10 sucks. It improved a bit after rooting, but basically there are some serious inefficiencies present when a phone with a 5,000 mah battery is drained in idle mode after a day and a half. Rooting it allowed better control, but still this phone will run out while not doing anything in three days while my Snapdragon 625 Xiaomi with 4,000 mah battery will last more than ten days in idle mode. (Niether phone has a sim card, so no network usage is factored in.) Having said all this, the phone is still a great buy for 97 Euro. It is waterproof which makes it the perfect camping phone, plus it serves very well as a music player in the shower.

it’s not easy to make a good rugged phone as it not easy to make a phone be water-proof and drop-proof, cope with cold and heat, and harsh environment, and empowered with big battery, strong signal and powerful navigation capacity, and at the same time stay slim and beautiful. AGM is the first rugged phone brand I’ve loved for long time. However, its phone is too expensive. Last year, I’ve learnt NOMU. Relatively, it’s a good brand of good quality and affordable price.
