The AQUOS Crystal X won't disappoint like its smaller sibling. It's bigger, bolder and faster. Unfortunately, it will leave US users out in the cold, as this one isn't making it across the Pacific.

The Crystal X has a 5.5-inch S-CG Silicon full-HD (1920 x 1080) "Crystal Display" that is cut at the edges for a frameless LCD panel.

It has a more powerful processor: the quad-core Qualcomm MSM8974AB clocked at 2.3 GHz, with 2 GB of RAM and 16 GB of built-in memory. Up to 128 GB microSDXC cards can be used to expand storage.

The camera is better as well: now 13.1 megapixels, autofocus, NightCatch II (f/1.9), real-time HDR, continuous shooting, multi-focal shooting, 4K2K video capture, Framing Advisor, Search Finder, Translation Finder, Photo Sphere functionalities included. Sadly, the camera is still lacking optical image stabilisation – only has a software implementation called "camera-shake reduction".

The Aquos Crystal X is capable of playing quad HD (4K2K) videos, and allows for zooming on a portion of the screen just like on a webpage or a still image.

Other functions include: easy screenshot by sliding your finger right from the display's top left edge; one-hand assist, which allows downsizing the active screen so that you can reach everywhere using one hand only; and a quick launcher, accessible from the menu shortcuts.

The Aquos Crystal X, too, flaunts the "Crystal Sound" function that uses Harman Cardon sound processing technology to deliver unmatched immersive music experience when using headphones or Bluetooth connected speakers. It is not yet known if this phone will come with a Bluetooth speaker by Harman Cardon, like the smaller Aquos Crystal.

VoLTE (Voice over LTE or the so called HD Voice) is supported for high quality voice when talking on the phone.

To aid the voice clarify function is Direct Wave Receiver, something Sharp first implemented in two years ago but have not equipped all models with: the technology to transmit the incoming signal using vibration of the body, not using airwaves. This allows holding the phone as convenient, without worrying about the position of the earpiece, which is no fully eliminated.

The Aquos Crystal X comes with Android 4.4.4 pre-installed.

Unfortunately, the Aquos Crystal X is not water- or dust-proof. It doesn't have Infrared, while Bluetooth is ver. 4.0. Supported Wi-Fi standards include a/b/g/n/ac.

The phone weighs 157 grams and measures 139 x 73 x 11 mm. It is available in red, black, and white. The battery is 2610 mAh and should last about three days in normal use, although the Aquos Crystal X does not use the IGZO display but has a standard S-CG Silicon LCD.
