With spring in full bloom, Yunhu Polar accompanies you on an underwater diving adventure.

Military-grade six-proof technology: waterproof, dustproof, shockproof, pressure-resistant, corrosion-resistant, scratch-resistant, low-temperature-resistant,ip68waterproof and dustproof certification,MIL-STD-810GU.S. military standard, impact resistance test certification. I think we can add one more proof――self-defense. This sturdy brick of a device — if you run into danger while out, you might as well use it for protection (though hopefully you won’t have to).

Logo detail display

Made of polycarbonate and fiberglass, offering high strength and hardness;TPUSoft material provides excellent shock-absorbing performance.

Yellow and black color scheme, with a simple and attractive design. Personally, I think it’s basically the Bumblebee of the phone world.

Software display

Comes with built-in outdoor tools such as an altimeter, pedometer, compass, flashlight, barometer, and magnifier.

Though I’m not sure why the pedometer and other outdoor tools can’t be used simultaneously — if you open another tool, the pedometer stops working,

but when you close the other tools, the pedometer starts up again automatically.

Photo display

Nowadays, aside from communication, another important function of a phone is taking photos. Shooting modes include multi-angle mode, panorama mode, motion track mode, scene photo mode, picture-in-picture mode, and it can even detect a peace sign and take a photo automatically.

Panorama mode

It can take several consecutive shots, giving off the vibe of a wide-angle DSLR.

Selfie mode with peace sign auto-trigger

Five-inchIPSHigh-definition large screen,1300megapixel camera equipped with a high-brightness Osram flash module, delivering exceptional low-light photography capabilities.

It’s said to support underwater autofocus, but due to cold temperatures in the north, I haven’t tried it yet.

Cold resistance experiment

Since this phone is calledPolarand claims to be“"Conquering Polar Glaciers,"”its cold resistance is worth testing. Beijing doesn’t get as bitterly cold as Harbin,

so I couldn’t conduct an outdoor cold resistance test, but being an“academic overachiever,”when conditions aren’t available, I have to create them myself.-20℃The fridge seems like a good option.

Experiment process:

Place the phone inside-20℃for10hours, then check if the phone shuts down or remains usable.

(The zip-lock bag is only to keep the phone separate from other experimental items, to maintain cleanliness, not for moisture-proofing — the bag wasn’t sealed during the experiment.)

the experiment concluded. The phone remained powered on. When taken out, there was a thin layer of ice on the screen, but the phone was still fully functional.

“A six-proof flagship, born from ultra-precise structural design, built to conquer polar glaciers.”

I think taking this phone to the Ice and Snow World would be great — no worries about it shutting down. And if I get the chance, taking it on a polar expedition wouldn’t be bad either.

Actually, I originally wanted to test-80℃, but I was afraid of damaging the phone components. Without official approval, I didn’t dare try it recklessly, so I had to give up.

Waterproof experiment:

After soaking, the headphone jack and data port remained dry.

When spring blossoms, it should be nice to go diving with your phone. Haha, actually, taking your phone to a hot spring is also an option.

High-end, personalized, extreme, challenging... (and so much more)...
