Sony today unveiled the mid-range and also waterproof Xperia M4 Aqua smartphone at MWC. I gave this smartphone a short test and will give you my first impressions here.

Release date and price

The retail price of the Sony Xperia M4 Aqua is around 300 USD.

Design and build quality

At first glance, the Xperia M4 Aqua looks like Sony's flagship smartphone, the Xperia Z3. But when you look more closely you can see some differences. Even though the back looks like glass, is its actually polycarbonate. The convex frame, which also appears to be made of plastic. The corners, so-called rubber bumpers, can absorb shocks and can prevent damage to the unit.

All in all, the Xperia M4 Aqua is an edgy smartphone which still feels good to hold, thanks to its rounded frame.

Bold colors, providing good viewing angles and contrasts, give the M4 Aqua's 5-inch display a quality look for a mid-range device. The resolution is 1280 x 720 pixels and provides the necessary clarity expected of a mid-range smartphone.

Special features

Like many other Sony smartphones, the Xperia M4 Aqua is waterproof. The connections for Micro USB and headphones are open, but the rest are hidden behind dampers.

Sony uses the M4 aqua on Android 5.0.2 Lollipop, with the manufacturer's own Xperia UI skin over the top. This was adapted, in its most recent version, to match Lollipop's material design. This is reflected through flatter icons and vibrant colors. It looks quite good. In the area of ​​personalization, you can change the color scheme according to your preferences and also customize the UI.

Thanks to the integrated octa-core Snapdragon processor 615, you'll have no worries about performance with the Xperia M4 Aqua. I found it to be snappy during in my short test.

On paper, the M4 Aqua seems to have a good camera. The main camera on the back boasts 13 megapixels, while the front camera has a wide-angle lens (88°) and a resolution of 5.1 megapixels - ideal for selfies and video chats.

With 2400 mAh of juice, the M4 Aqua battery is shockingly small. But it's too early to make a final judgment on it. Once we have the M4 Aqua subjected to some more rigorous tests, we'll give you our final verdict.

    Everything else about it sounds right up my alley! It'll make a FINE addition to my (Mid-Range) Smartphone Collection!! It'll get along just fine with my Samsung Galaxy 🌌 S4, my Amazon Fire 🔥 Phone and my 2 OnePlus Ones📱!! Not to mention my Asus Google Nexus 7 (2012) with Android 5.0.2 Lollipop 🍭! 😉
