Review: Rugged, Feature-Packed, and Worth the Leap — Loving This Phone! - I waited to review this phone until I had time to really test it. I came from an older Samsung and was hesitant about switching brands, but for the price and features, Ulefone's Armor 28 Ultra Thermal caught my eye—and I'm glad I took the risk. This thing is a beast. The thermal and night vision cameras are more than just novelties—they’re genuinely useful, especially for work and exploration. The battery life is phenomenal, and the rugged build feels like it could survive just about anything. Waterproof, sturdy, and packed with bonus features like support that I can plug in extras like the devices like the uSmart E03 Rotatable Endoscope or the uSmart C01 digital microscope. I do not own any of these yet but look forward to trying them out. I mostly keep the screen brightness low but at full blast I can see the screen in direct sunlight no issues that is a huge win, this phone does more than most there a quite a few settings I have not tried out. A few things to consider: > No SD card slot (missed it, but the dual SIM is a plus). > A learning curve with Android 14 and some UI changes. > The weight and size are substantial—definitely not for small pockets—I don't mind it as a tradeoff for power and durability. > The rear display is cool, but I keep it off unless recording. And, did I mention speed and the huge battery? Love it! Highly recommend if you're looking for a durable, all‑in‑one rugged phone with actual utility tools built‑in. I carry this phone everyday and really enjoy it. *Some of the photos show a case that did not come with the phone. November 2025 one update: make sure you get an extra screen protector for some reason mine already cracked. Still enjoy the phone.
Review: It boot loops and freeze multiple times - This phone waa started to glitch and freeze randomly the past weeks since i got it i googled and found out it was a common issue on this phone last night it totally went boot loop and no way to do even recovery mode or hard reset. Frustrated the price of 1k$+ unbreakable body but terrible software in gaming wild rift was laggy and not smooth not i expected. Now i have expensive brick in hand.

### ⭐⭐⭐ Good but worth $800 not $1200
*by M***T on May 29, 2025*

Would love to give it more stars. But the camera is laggy. Doesn't focus well. I downloaded an AI camera app that improved it but still not great... The thermal, battery, performance, all 5 stars but regular 50mp camera for its claims is quite lacking... I think even the infrared camera works better than the main 😒. Solid durability. I think it's a solid $800 phone not worth the $1200 price tag sadly.
