Hitting the shelves at the beginning of 2015 is AU & Sharp's Aquos Serie mini SHV31 smartphone. The pre-installed OS is Android 4.4 KitKat.

The Aquos Serie mini SHV31 has a 4.5-inch Full HD (487 ppi) display utilising the IGZO LCD technology for low power consumption, coupled with the minimal bezel design of the EDGEST family.

The SHV31 relies on a quad-core MSM8974AB processor clocked at 2.3 GHz, has 2 GB of RAM and 16 GB of built-in storage (use microSDXC cards to expand).

The main camera is a 13.1 megapixel CMOS shooter having features like Real-time HDR, NightCatch II (f/1.9) for taking quality photos in dark environments, and a LED flash.

The front camera is just 1.2 megapixels. Sorry selfie-maniacs.

Supported radio frequencies include:
FDD-LTE: 2100(B1)/1800(B3)/800(B26)/700(B17) MHz
WiMAX 2+(TD-LTE): 2500(B41) MHz
W-CDMA: 2100(I)/850(V) MHz
GSM: 1900/1800/900/850 MHz

Because the SHV31 was released a few months before the introduction of mandatory SIM-lock release (if requested), it cannot officially be SIM-unlocked and is therefore tied to the au network. There may exist unofficial unlocking methods but none that I am aware of.

A Nano IC Card 04 is required to use this device and the VoLTE function.

The Aquos Serie mini SHV31 comes with a 2,120 mAh battery, which should be good for a couple of days on a single charge, helped by the power-efficient IGZO LCD. AU's website says it should be able to last up to 540 hours (over three weeks!) in standby mode.

Looks like dust resistance has made a return on Sharp phones, having missed for two collections: the AQUOS Serie mini SHV31 is both water- and dust-resistant.

The device weighs just 118 grams and measures 63 × 124 × 9.9 mm. It is available in cyan, magenta, white or black.
