Reviews for the Ulefone Armor 28 Ultra

100% I put the Ulefone Armor 28 Ultra through its paces — here’s why it’s a top rugged phone
Source: Techradar English
I’ve reviewed a quite a few rugged smartphones over the last year, and many of them have impressed, with each carving out its own niche—whether featuring projectors, camping lights, ultra-high-capacity batteries, or infrared capabilities. While the Ulefone Armor 28 Ultra doesn’t include a projector, it does have pretty much everything else. What really makes this rugged smartphone stand out is just how fast the processing is and how much it feels like a regular premium smartphone. Okay, it is a little bulkier and heavier, but few other smartphones can withstand the drops and harsh environments that this phone takes in stride.

Ulefone Armor 28 Ultra Smartphone Review
Source: OI Spice Tech News English
The Ulefone Armor 28 Ultra has all the latest and the best hardware inside to make it a proper flagship rugged smartphone. Everything from the design & display to the performance & battery is fantastic. Even the camera performance is also quite good. It may not be on the same level as flagship phones from Samsung and Apple, but it’s not far behind. You no longer need to choose between a flagship and a rugged smartphone. The Ulefone Armor 28 Ultra is designed to deliver the best of both worlds and does so gracefully. Not to mention, this phone is essentially a brick that will work in any condition and can easily survive hard falls and drops. It’s an excellent smartphone that has no known alternative.
