WiMax 2+ adds support for high bandwidth single-channel support
Japan's KDDI Corp. (
) is currently stuck in third place, having been for the moment passed by Softbank Corp. (
has 30.3 percent
(as of Feb. 2014) of the mobile market in Japan (via its SoftBank, eMobile/eAccess, Willcom, Wireless City Planning (WCP) brands).
KDDI has 28.9 percent of the market
via its au, Okinawa Wireless, and UQ Communications brands. Both trail market leader NTT Docomo Inc. (
) which controls a whopping 40.8 percent of Japanese connections.
The fierce competition on the high-tech island nation has led to great high-end handsets. KDDI was pleased this week to announce that it would be carrying the HTC Corp. (
) 2014 J Butterfly. It did not indicate whether its deal to carry the device was exclusive.
The HTC J Butterfly is the latest in a series of high-end handsets from HTC that have made it a serious contender in Japan. Previous models included:
HTC J (Japan)
HTC One S
HTC Butterfly (Japan)
HTC Droid DNA
(U.S.; Verizon Communications Inc. (
HTC Butterfly S (Japan)
HTC One (M7)
No U.S. release
The HTC Butterfly J (HTL23) continues in the line of the Butterfly S, incorporating features from the same-year U.S. HTC One model (this time the
2014 HTC One M8
), while improving the spec somewhat.
The published spec includes:

Clearly the star of the show is the advanced wireless technologies onboard the Japanese HTC One M8 variant. Japan is
among the most advanced nations in the push for LTE-A
, and KDDI is on the forefront of this push. It's making clever use of its adjacent 2 GHz spectrum as WiMax 2+ for slightly higher throughput on a single antenna, when the 800 MHz band isn't available for aggregation. When the 800 MHz and 2.1 GHz band are available, it can
go even faster via aggregating the two downlinks

The body is undeniably colorful. Some may view the switch from the aluminum unibody to the colorful plastic body as a "cheapening" of the U.S. variant, but in reality it's more of a calculated move by HTC to appeal to Japanese buyers. While HTC may partake in some cost savings, the bigger underlying reason for the colorful lineup is because Japanese buyers tend to gravitate towards colorful devices. Phones like the colorful Apple, Inc. (
) iPhone 5C that
saw disappointing sales in the U.S.
saw relatively strong sales in Japan.
Overall there are no quantum leaps in the J Butterfly, but the addition of support for more advanced wireless technologies and formalization of the waterproofing/dustproofing (which weren't formally guaranteed on the HTC One M8) are nice nods to Japanese buyers.
KDDI writes that HTC will be holding a press conference on Aug. 19 at its Tokyo, Japan local headquarters to officially announce the device. The phone will launch "as early as late August" on au and partner networks. The price should be announced at the press conference later this month.

JBL instead of BoomSound
7/31/2014 4:52:45 PM
I remember reading elsewhere that the BoomSound speakers have changed and are JBL sets.
The speakers don't really go with the device but I could live with that should this ever make its way to the US and on Verizon (instead of that pitiful junk called the One Remix). JBL is good at making the most out of a limited space (I have a few of their bluetooth speakers) and I have high hopes for speakers on the phone if it is them that's making it.
It's also good that they upped the MP count for those that want to zoom in and crop without getting rid of the depth camera that I happen to like on my M8.
