Verdict

The Ulefone Armor 28 Ultra is a high-performance, ultra-durable 5G rugged smartphone released in March 2025, powered by a 4nm MediaTek Dimensity 9300+ processor and running Android 15. Key features include a massive 32GB of RAM (expandable) and 1TB of UFS 4.0 internal storage, a large 10,600mAh battery with 120W wired and 50W wireless charging support, and an expansive 6.67-inch 120Hz AMOLED main display paired with a 1.04-inch AMOLED sub-display on the rear. Photography highlights a versatile triple camera system with a 50MP main (1-inch Sony IMX989 sensor), a 64MP night vision camera with infrared LEDs, and a 50MP ultra-wide lens, capable of 8K video recording. A major pro is its exceptional durability, certified with IP68/IP69K and MIL-STD-810H ratings, making it highly resistant to water, dust, and drops. The phone also features a uSmart connector for professional accessories (like endoscopes) and AI tools. Potential cons include its substantial weight (450g) and bulkiness compared to standard smartphones, and the rear charging slot may be too narrow for some third-party USB-C cables.

Very fast 120W wired flash charging (reaches 40% in 10 minutes) and 50W wireless charging support.
Good camera quality for a rugged phone, including a capable 50MP ultrawide lens and 64MP night vision camera that works well in total darkness.

Bright main AMOLED display with a smooth 120Hz refresh rate.
Massive 1TB of storage, which is a generous feature.
Useful extra features such as a 3.5mm headphone jack, a Usmart expansion port for accessories (endoscopes, microscopes), and customizable buttons.
Strong build quality and design, feeling solid and well-built in the hand.

What customers dislike about Ulefone Armor 28 Ultra (32GB + 1TB)?

The phone is heavy and bulky (around 450g), making it less suitable for everyday pocket carry.
Some users report software bugs and glitches, including issues with the always-on display not staying on, app lag, and the battery manager restricting apps.
It can get hot when charging or under heavy use, such as satellite navigation or demanding tasks.
The small secondary rear screen is considered a gimmick by some users, who would prefer different features.
The camera's still shots can be a bit too sharp due to post-processing, and the zoom quality is average.
Mono speaker setup lacks depth and quality compared to stereo speakers found on many premium consumer phones.
The dedicated camera button only works with the stock camera app.
The charge port is narrow, so some thicker USB-C cable tips may not fit.
Some compatibility issues with certain North American carriers like Rogers Wireless, AT&T, and Verizon.

Summary of the review

Ulefone Armor 28 Ultra camera tests are out: Video

The Ulefone Armor 28 Ultra is presented as a rugged smartphone combining durability with flagship performance. Its triple-camera system features a 1-inch Sony IMX989 sensor supporting 8K video and excelling in low light, although skin tones may appear warmer in processing. Specialized cameras include a 64MP night vision lens with infrared LEDs and a 50MP ultrawide lens with macro capabilities, alongside a rear AMOLED display and a physical camera button. Powered by a MediaTek Dimensity 9300+ processor and up to 16GB of RAM, it offers high speed. However, the phone's design results in significant weight (453.6g) and bulk due to its large 10,600mAh battery and reinforced body. Drawbacks also include a single mono loudspeaker and the absence of EIS for the 50MP front camera. While valuable for professionals, the $900 price and uncertain software updates could be limiting.
