Monsters from Asia: the Japan-exclusive J Butterfly HTV31, or one of HTC's most decked-out phones ever


So far on our regular Monsters from Asia column we've steered away from mainstream manufacturers and have been focusing on truly exotic devices instead. To feature an HTC device, then, might sound like a betrayal, but the smartphone we'd like to highlight today is anything but a standard issue HTC device.

Say hello to the J Buttefly HTV31, a phone one can only get his hands on if he lives in Japan or manages to export one. Getting a unit out of the island is an intriguing prospect, however, as the HTV31 just so happens to be one of HTC's most decked-out smartphone to date. Indeed, we start off with a 5.2-inch of a display, with a Quad HD resolution of 1440 x 2560 pixels, good for 565 ppi. The device is powered by a 64-bit Qualcomm Snapdragon 810 processor with eight cores and an Adreno 430 GPU sidekick, along with generous 3 gigs of RAM. There's 32GB of storage on board, though you can expand upon that with up to 200GB more so long as you have a properly dense microSD card for it.

Moving onto imaging, and this is kind of an exciting part of the HTV31, we're looking at a 20-megapixel 'Duo Camera' setup at the back, complete with a dual LED flash and optical image stabilization for better low light performance and less shaky video footage. As can be expected, the camera shoots 4K UHD video. Even more impressive, however, is the camera up front — a 13-megapixel unit. Judging by HTC's previous efforts in this very area (with the Desire EYE), the HTV31 ought to produce some great selfies.

Finally, HTC rounds off the package with Android 5.0 Lollipop with its proprietary Sense UI, a 2,700 mAh battery with quick charging, dual front-facing BoomSound stereo speakers, and — as you can expect from any self-respecting device on the Japanese market — an IP57 certification, meaning the J Butterfly is dust- and water-resistant. 

The HTC J Butterfly HTV31 is available with au KDDI in Japan, and costs the equivalent of about $630 with a new contract (over 24 monthly payments).

If u combine all the digits of "810" u have the number 9, the number also exists in their flagship, the M9, which uses the snapdragon chip, does this seem familiar? Also, HTC is not putting out a new flagship until 2016, which means that the M9 will be a flagship until that time (2+0+1+6)=9, and there are 3 letters in htc , which if u square, gives you the number 9 as well. Illuminati confirmed!

This phone should have been called One M9, then htc could turn back to form.

Correction: "doesn't slow down in its throttled state".

I don't pick and choose what news I believe. Right now, the overwhelming majority of reports are that the 810 had massive heat issues, so much so that there was a new version released which throttled the performance of the chip. That doesn't mean that the consumer's opinion has changed about the chip or of any phone that happens to have it.

You should pick and choose. The tech press is comprised mainly of idiots.

When there's conflicting reports I do, but please not that I had stated "overwhelming majority" in my comment. I don't choose to deny something simply because I don't like it, but I will call it into question if I suspect biased reporting. Given the numerous reports and the simple fact that Qualcomm themselves have released a revised 810 that has been under-clocked makes it rather difficult to deny that there was no issue.

So apart from the processor, isn't it the same as the m9+??

No, it also has a 13MP FF camera w/ dual LED flash, and IP57 certification.

Nope. The M9+ doesn't have a 13MP camera with flash on the front, it has a 4MP Ultrapixel camera. The M9+ isn't dust- and water-resistant. The M9+ isn't made of plastic, it is made of metal. The M9+ has a fingerprint sensor. The M9+ doesn't use a Snapdragon 810 processor. It uses a Mediatek MT6795T processor. So yeah, they're not exactly the same.

Looks like a remote control.

This phone might do better than M9 as a flagship device.

Add a metal build, and fingerprint scanner to this and could this be the HTC Aero for the US?

lol, they should have given this the metal construction found in the M9 and released it as the flagship globally, as others above me have suggested. idiotic move by HTC.
