With the Dimensity 9300+ and 16GB of RAM, the Ulefone Armor 28 Ultra performs as well as any Android flagship, but it can go places they don’t dare – it’s rated IP68 for water resistance (up to 2m for 30 minutes) and IP69K (hot water jets). Additionally, it has been tested for 2m drop resistance. The phone can survive extreme temperatures too and can work between -30°C and 55°C.
Besides the chipset, the other standout
“normal” feature is the 1-inch sensor in the main camera, the Sony IMX989
(50MP, f/1.9). Daylight photography can also be done with the 50MP ultra wide
camera (Samsung JN1) or the 50MP selfie camera (JN1 again). This being a
Ulefone device, it naturally has a night vision camera too – a 64MP module with
an 80° FoV (based on the OV64B1B sensor). And as you can tell by the name,
there is a thermal camera too.
Thermal imaging is done with the ThermoVue
Pro app and delivers video at 256 x 192px. This is the highest resolution
thermal imaging camera from Ulefone yet. It’s great for professionals (e.g.
checking for leaks) and adventurers alike (e.g. it’s another way to see in the
dark). Additional accessories can be hooked up to the uSmart Expansion
Connector (e.g. an endoscope camera).
Moving on to the normal features, the
Ulefone Armor 28 Ultra features a 6.67” OLED display, an FHD+ panel with 120Hz
refresh rate and a peak brightness of 2,200 nits. This is Ulefone's first
rugged phone with an OLED display, by the way. And that's not all, there is a
secondary circular display on the back too, which shows the time and other info
when the phone is face down. The phone has 16GB of LPDDR4X RAM (+ up to 16GB
virtual) and 512GB of UFS 3.1 storage, which can be expanded via microSD. The
card slot can also hold two nanoSIM cards.
As is typical for the brand, this phone
has a monster battery, 10,600mAh (41Wh). That’s double what a typical phone
has, so fast charging is essential and Ulefone doesn’t disappoint – the phone
does 120W over USB-C and 50W wirelessly. This is a 5G phone with Wi-Fi 6 and
Bluetooth 5.4 support. NFC is on board too, as is an IR blaster. It is equipped
with a single speaker, a powerful 1.5W unit, as well as a 3.5mm headphone jack.
The built-in FM radio receiver doesn’t even need the headphones as it has an
integrated antenna.
