Best Rugged Smartphones (Unlocked) 2018

For those with a demanding job or lifestyle with constant exposure to environmental hazards, a rugged smartphone with military-grade protection may be the best option. A rugged smartphone is also a smart choice to use as a second phone when traveling. Ruggedized smartphone models meet military testing standards for protection against shock, water, dust, extreme temperatures, and vibration. They are water-resistant and can withstand submersion in shallow water for a limited time. When using a rugged smartphone, keep in mind that while these phones have been tested to military-specified standards, care should still be taken as glass screens can crack and drop test ratings do not guarantee you will always have the same results in the real world. Here are the best rugged smartphones for 2018 that are available unlocked. The following phones will work on GSM carriers like AT&T and T-Mobile but not CDMA carriers like Sprint and Verizon.

Ulefone Armor 2

Best Value Rugged Smartphone

Ulefone Armor 2 Best Value Rugged Smartphone

The Ulefone Armor 2 is part of the new generation of rugged phones that offer significant upgrades over their predecessors without breaking the bank. This 5.0-inch, dual-sim phone runs Android 7.0 Nougat and is powered by an octo-core 2.6GHz Helio P25 CPU with 6GB of RAM and 64GB of storage. With its expected IP68-rating, the Armor 2 can be submersed up to one meter underwater for an hour and is resistant to dust, dirt, and sand. The screen is full HD 1920×1080 constructed of Gorilla Glass 3 and the 4700mAh battery ensures all-day operation. The 16MP-rear and 13MP-front cameras allow underwater shooting with the waterproof shutter button. Other modern features include a front fingerprint sensor and USB Type-C port. Unique outdoor features include a barometer sensor and SOS button.

PROS: Good all-around specs, affordable price, high-quality rugged exterior
CONS: Somewhat heavy at 270 grams

Also Consider: The Blackview BV8000 Pro is another recent phone with very similar specs to the Armor 2. We recommend the Armor 2 over it because the BV8000 Pro does not have a sealed charging port. Although the port is waterproof, it needs to be completely dried out before charging otherwise damage can occur. The BV8000 Pro also has a slightly inferior CPU and the exterior appears to be less rugged.


Rugged Smartphone with Wireless Charging

DOOGEE S60 Rugged Smartphone

The DOOGEE S60 is another current-generation rugged phone that has similar specs as the Ulefone Armor 2 and surpasses it in a few areas. Like the Armor 2 it is an IP68-rated dual SIM phone running Android 7.0 with the same CPU and memory setup and a fingerprint sensor. What differentiates it is the larger 5.2 FHD display with Gorilla Glass 5, the 21MP rear camera with a larger Sony IMX 230 sensor, 5580mAh battery, and wireless charging. Also the S60 has a traditional headphone jack while the Armor 2 requires a USB Type-C to 3.5mm headphone adapter cable (which is included). Unlike the Armor 2’s USB Type-C it has a micro USB charging port. DOOGEE is an obscure brand in the west but user reviews of its non-rugged phones have been favorable.

PROS: Good specs, good camera, big battery, wireless charging
CONS: On the pricier side for a budget phone

AGM X2 Rugged Smartphone with Dual Rear Camera

If photo quality is important then the AGM X2 should be at the top of your list. As is becoming the trend with many mainstream flagship phones, this IP68-rated smartphone has a dual-camera setup with two 12MP Sony IMX386 1.25-micron large-pixel rear cameras, with monochrome and RGB sensors to capture more light and details. This camera setup allows the user to create photos with the “bokeh” blurred-background DSLR effect. The phone also has a 16MP Samsung S5K3P3 front camera for superior selfies. The MIL-STD-810G-compliant phone can handle water immersion up to 1.5 meters deep but it also has a patented floating module that prevents the phone from sinking. Other notable features include a 5.5-inch AMOLED full HD display with Gorilla Glass 5, 6000mAh battery, QUALCOMM MSM8976SG Octa Core with Android 7.1, 6GB RAM/64GB ROM, fingerprint sensor, air pressure sensor (altimeter/barometer), VOC (volatile organice compound) sensor, 3.5mm headphone jack, and USB Type-C port.

Rugged Smartphone with Thermal Imaging, Laser Measurement, Air Quality Sensor

Rugged Smartphone with Dual Rear Cameras and Android 8

DOOGEE S55 Rugged Smartphone

Despite the model number, the DOOGEE S55 is actually a newer model than the DOOGEE S60. As such it runs Android 8.0 but is a more budget-oriented phone than the S60. It has a larger 5.5-inch screen but a lower resolution (720 x 1440) with Gorilla Glass 3 (versus the S60’s Gorilla Glass 5). The S55 also has a slower 1.5 GHz Cortex-A53 quad-core GPU and an inferior GPU as well. We recommend the S60 over the S55, but the S55 is a decent IP68 water-resistant and dual-sim rugged smartphone that would be a good budget option for travel or casual use.

PROS: Low price, large 5500mAh battery, fingerprint sensor, dual rear cameras
CONS: Not readily available in western markets
