Review Image by Donald T
I am thoroughly impressed with the Ulefone Armor 28 Ultra. Beyond its durability, the attention to detail in its construction is remarkable. While some compare rugged phones unfavorably to mainstream flagships in terms of aesthetics, this device feels refined and premium in its own right. The camera system is outstanding, delivering professional-grade results. The ergonomics are great, making it easy to hold despite its size, and the display brightness is impressive even in direct sunlight. Performance-wise, the processor is top-notch and handles everything with ease. If you need a rugged phone that doesn't compromise on specs, this is the one to get ... show more

    • Love the phone. Big bulky and heavy but has amazing specs and features
Love the phone. Big bulky and heavy but has amazing specs and features I love this phone. It's incredible. The display is amazing and bright, the CPU and RAM are very high which helps me with large memory demands such as editing raw photos. The phone is large and heavy but if you can get over it, you have basically a computer in your hand. I love the headphone jack, microSD card slot and indicator LED. My only complaints are the microphone is very bad quality, muffled and picks up wind noise . I suppose that's because it's water sealed but very unimpressed with that. Also, the cameras are high Megapixel but the photos don't look right and if you aren't perfectly still the photo/video will be blurry and choppy. Also you can't access wide angle camera from apps like Snapchat. The Samsung phones let you choose .5x zoom but this phone doesn't. Overall it's the best choice. ... show more

    • Does Not Connect My Pacemaker
This marks my third time buying this phone. This is likely the greatest phone I've ever had, in every way.The problem I have with it is a game changer. I use a heart pacemaker. This phone cannot activate the programs and applications required for communication with my cardiology clinic. Every time I returned the phone, it was only after struggling for hours to connect it, even with help from the pacemaker technicians. It worked with all the other phones I've had. We are unsure why it's not connecting, since it has everything needed to establish a connection. It simply won't happen. I reached out to Ulefone for help, but their only suggestion was to return the phone, which wasn't helpful at all. I asked them could that could be the problem? The phone is initially equipped with Android 14. The phone receives the Android 15 update via the internet. However, it stops working after the Android 15 update. I'm forced to revert to my previous phone, which initially ran on Android 15. So, I am returning it for the last time until I am assured it works with the required Pacemaker app! ... show more

This phone is amazing! The battery easily lasts me a full day of heavy tiktok lives and gaming with around 40% charge left before bed. This phone charges so fast your jaw will drop to the floor! The speaker is phenomenal! I can hear everything even with background noise! Perfect for a mechanic like me in the field. The display is beautiful and the camera surprised me with how good it is. Definitely perfect for me with ULTRA FAST data transfer, 2TB expandable storage, perfect balance of battery and weight and probably the best chip set in any rugged phones available today. Highly recommend to my fellow blue collar workers looking for an absolute tank with flagship features! Ulefone did an excellent job making this phone look,feel and perform with uber high quality in my opinion. I will keep this review updated if my opinion changes negatively for any reason over time. ... show more

    • Early model failure
I bought a early model, it got warm cooked itself. Note that was with the original 9300 chip not the 9300+ no comment there but up until that point I loved the phone but I had to return it and now I'm rocking the 29 pro similar but bigger battery and weaker camera but I reviewed that on its page.

    • EXCELLENT PHONE , AND THE COMPANY THAT I PURCHASED IT FROM
This is the best cellphone purchase I ever made. The phone is exceptional with features, and durability. I highly recommend this phone if you want a phone that will last. You don't have to be concerned with the phone breaking because you dropped it, or got water on it. The company that I purchased it from is also exceptional. Daniel, the customer service representative that I have been dealing with has helped me with post purchase questions. Daniel is very helpful, and answers your questions quickly to resolve any of your concerns. In a time of poor products, and customer service, this company shines!

    • Great Rugged Phone, but Touchscreen Issues
Excellent phone with tons of features and a strong, durable build. As a rugged device, some functions may be slightly affected by the design. Unfortunately, after a few days, the touchscreen stopped responding, which I later learned is a known issue. I have to say, though, the Ulefone support team handled it very professionally and were super friendly throughout the process. ... show more
