The Winter 2013/2014 collection features two "mini" devices by Sharp: the AQUOS Phone Xx mini 303SH by SoftBank and the Aquos Phone Serie mini SHL24. Don't be fooled by AU's Serie or SoftBank's Xx series code-names: in terms of hardware, they are the identical.

The "mini" Aquos Phone comes with 4.5" display and utilises the IGZO display backlight technology, increasingly found on high-end Sharp smartphones. It wields the impressive Full HD (1920 x 1080 px) resolution, resulting in a whopping 487 ppi – and boasts a very thin bezel allowing the screen to occupy 75% of the entire front surface of the phone. Sharp calls the series of phones where screen estate has been increased in this manner EDGEST.

The 303SH/SHL24 is powered by the same processor as its bigger sibling, the 302SH – a Qualcomm Snapdragon 800 (MSM8974), whose four cores are clocked at 2.2 GHz. The amount of installed operating memory is 2 GB and the built-in storage space is 16 GB, expandable using microSDXC cards.

Onboard is a 13.1 megapixel CMOS camera with BrightEye + NightCatch, featuring a f/1.9 lens aperture, HDR shooting and background/foreground blur, all aided by electronic image stabilisation.

The inner shooter is the humble 1.2 megapixels, fixed focus.

Conveniently, the rear camera now comes with a built-in translation feature which makes it possible to capture English text, translate it into Japanese, and embed the translation in the original photo!

The Feel UX user interface found on all newer Sharp phones has seen some improvement and now offers a full screen image on the lock screen and other advantages. There is also a built-in quick launcher which will open a list of application shortcuts at the tap of a finger for convenient one-hand use.

The "mini" AQUOS Phone boasts the Feel Musician functionality offering an amazing listening experience with DTS sound and the ability to automatically launch the music player when headphones are plugged in, resuming playback from where you left off last time.

Like all Sharp devices, this one too comes with an eco feature allowing energy saving settings to be applied with a single touch. Together with the most energy efficient display in the world, the IGZO LCD, the 2120 mAh battery promises no less than two days of full use in one charge.

The installed OS is Android 4.2. No upgrades were released.

The dimensions of the AQUOS Phone Xx mini 303SH and the AQUOS Phone Serie mini SHL24 are 63 × 124 × 9.9 mm. The devices weigh just 117 grams. They are waterproof – capless! – and dust-proof.

OneSeg digital television reception is supported.
