- Analysis by KJ David
One of NUU Mobile's first attempts at a rugged smartphone and also one of its earliest 2019 releases, the NUU Mobile R1 is a gritty budget-class Android in terms of technical pros and cons. Among its weakest points are its ancient-sounding (as of this Phonerated review) 2-megapixel-only front-facing camera 
and run-of-the-mill 8-megapixel primary rear-facing cam .
The above-mentioned cons seem to be necessary trade-offs to keep the R1's price point within entry-level territory, though, since NUU houses its specs inside a toughened shell that passes both IP68 
and MIL-STD-810G rugged certifications. The former makes its 0.51-inch-thick physique impervious to water and dust, while the latter rigs it with native resistance to accidental impacts as well as to temperature extremes.
This low-budget prepaid contender (Check out some of its prepaid competitors here) also lists a sizable 4000mAh battery among its pros, giving it a huge advantage versus a lot of other entry-level smartphones, most of which stick to roughly 2500mAh power caps only.

Its processing components include a measly MediaTek MT6739 quad-core processor clocked at 1.3GHz and an equally-basic 2GB RAM. When it comes to storage, while its 16GB native memory is respectable, coming from a budget-class rugged Android, its support for no more than 32GB of external memory sounds a tad problematic, considering that many of its rivals in this category support 64GB and even 128GB external memory cards.
Joining the aforementioned pros and cons are a standard 4G LTE network adapter, two micro SIM card slots, and a passable (for a phone within its price group) 5-inch 1280 x 720 HD display hardened by a damage-resistant Gorilla Glass finish . Mimicking several other rugged models, it rocks a plain Black exterior, with the Android 8.1 Oreo operating system tying everything together.
All said, NUU's R1 is, overall, an entry-level smartphone, but its rugged housing and robust battery pack certainly makes it more ready for the outdoors than most other models in its category.

We are talking about an above-average screen, making it a phablet: 5 inches and a resolution of 1280 x 720 pixels means about 10.68 square inches and an image sharpness of at least 293.58 dots per inch (DPI)!
It includes a high-megapixel camera (8-megapixel)
