The M4 Aqua and the M4 Aqua Dual are now to be found at retailers across Europe, the Middle East, and parts of Asia. The phone is generally being offered in white, black, and "coral", but there are certain markets which also get a silver version.
The Sony Xperia M4 Aqua is a midranger that boasts a similar design to the company's flagships, IP68 rating for water and dust resistance, and even a capless USB charging port.
On the other hand, the Xperia C4 (pictured above) is all about selfies. The handset has a 5 MP wide-angle front-facing camera that comes equipped with a LED flash, to ensure that it captures perfect selfies regardless of lighting conditions.
Otherwise, the C4 is a pretty capable device with its upper-midrange specs. It will be found in stores in the Asia-Pacific region this week. After that, it will slowly make its way to more places, with the global rollout expected to be complete "within the coming weeks".
Im have a C4 and for some reason the camera app takes time to launch when all apps are killed. Also, when I need to make a phone call, it takes time to dial the chosen contact person.
I am considering to buy this phone...can anyone tell me how is the performance of the phone..i am pretty confused with the reviews....
Aqua m4 or 4 ?
