Attending events like IFA 2024 further cemented their position as leaders in innovation and ruggedness. This commitment to quality is evident in every aspect of the Armor 28 Ultra.
Design and Build Quality

Ruggedness and Durability
From the moment I held the Armor 28 Ultra, its robust build stood out. It boasts MIL-STD-810H compliance and IP68/IP69K certification, ensuring it’s waterproof, dustproof, and shockproof. Whether you’re hiking, working on a construction site, or simply worried about accidental drops, this phone can handle it all.
Armor 28 Ultra Thermal Variant
One unique feature is the Armor 28 Ultra Thermal Variant, which includes thermal imaging capabilities. This addition is particularly useful for outdoor enthusiasts and professionals who need to see in low-light conditions or monitor heat signatures.

The dual-display design is another standout feature. The main AMOLED display is vibrant and sharp, while the secondary display adds functionality without compromising the ruggedness. This design enhances usability, allowing for quick access to notifications and apps without unlocking the main screen.
Material and Build
While the Armor 28 Ultra is built to withstand tough conditions, it’s important to note that it lacks Gorilla Glass, which might be a downside for those concerned about screen scratches. However, the overall aesthetic is sleek, and the available color variants add a touch of personalization.

Powered by the MediaTek Dimensity 9300+ 5G SoC, the Armor 28 Ultra delivers impressive performance.

Display Features

AMOLED Display
The AMOLED display is one of the highlights. It offers vibrant colors, deep blacks, and excellent brightness levels, making it perfect for both indoor and outdoor use. Whether I was watching videos or browsing the web, the display quality was consistently impressive.
Refresh Rate
A 120 Hz refresh rate ensures smooth visuals, especially noticeable when scrolling through apps or playing games. This high refresh rate significantly enhances the overall user experience, making interactions feel more responsive and fluid.
Secondary Display
The secondary display is a practical addition, allowing quick access to essential information without disrupting your main screen activities. While it’s a useful feature, some might find it redundant, especially if they prefer a more minimalist design.
