Sony announced recently that the new Xperia M4 Aqua device will be released in Canada sometime in June. But there was no news about a release date for the United States. Now, however, interested American buyers can purchase Sony's newest mid-range phone from Amazon.

Amazon is offering an unlocked version of the handset for US$349. It is also worth noting that the retailer is selling the 8 GB variant of the handset, model number E2303, according to Phone Arena. This particular version only comes with 1.26 GB of free storage space. Sony has added a microSD card slot for further expansion, however. As long as you don't have a problem buying a microSD card, the Xperia M4 Aqua is one of the best mid-range devices on the market. It comes with a dust- and water-resistant exterior, and it is IP 68 certified.

The smartphone features a 5-inch IPS LCD display, packed with a 720 x 1,280 pixel resolution. The mid-range handset resembles the Sony Xperia Z3. However, this device is made with plastic, whereas the Xperia Z3 comes with Sony’s trademark mix of metal and glass -- a common style among high-end handsets -- according to Phone Arena.

Under the hood, the Xperia M4 Aqua is powered by a 64-bit, octa-core (Qualcomm Snapdragon 615) processor and backed by 2 GB of RAM configuration. The device runs on Android 5.0 Lollipop OS. Furthermore, the handset is available in either 8 GB or 16 GB of storage space. This device supports microSD cards for expansion of up to 128 GB.

The Xperia M4 Aqua sports a 13-megapixel rear-facing camera, in addition to a 5-megapixel front-facing lens for selfies. The battery unit can last up to approximately 13 hours of talk time and 685 hours on stand-by. Apart from the standard connectivity options, this Xperia handset also supports LTE and NFC. The device is available on Amazon.
