Japan is well-known for its seriously interesting mobile products, and the Infobar A02 on KDDI doesn't disappoint on design or creativity in the least. The Infobar series has traditionally been a design-leading line, and the A02 follows along with a striking thin unibody design in red, white and blue varieties. The design continues onto the interface, which is built on Android 4.1 -- although you wouldn't know it by looking at the homescreen. Closer to the paradigm of Windows Phone, the Inforbar uses a tiled interface comprised of smaller app tiles and larger widget tiles, in a vertical scrolling list.
This handset is actually manufactured by HTC, and has some top-notch specs on the inside. We're looking at a 1.5GHz Snapdragon S4 Pro processor, 16GB of (expandable) storage, 1GB of RAM, 720x1280 TFT display, 2100mAh battery and of course LTE. Like many high-end Japanese handsets, the Infobar A02 is also waterproof and dustproof, and includes NFC for mobile payments as well as a 1seg TV antenna.
This is quite an interesting handset on all fronts, and worth a look at some of the materials on KDDI's product page for the phone. If you're interested, head to the source link and check out the galleries, especially the pictures showing the lineage of Infobar design for the last 10 years.
