Overview, design và features


First spotted at MWC earlier this year,the Sony Xperia M4 Aqua is a S$498 mid-range điện thoại cảm ứng that looks a bit like a more affordable, plastic version of Sony"s new Xperia Z3+ flagship smartphone. In many ways, that"s actually pretty accurate.

Design & handling

One can’t accuse the Xperia M4 Aqua of looking inferior or shoddy despite being a mid-tier smartphone. With a glass front & back, the Xperia M4 Aqua bears more than a passing resemblance lớn the Xperia Z3+ when viewed at from a distance, although the Xperia M4 Aqua is slightly thicker. The Sony Xperia M4 Aqua giaithuongtinhnguyen.vnes in three colors: black, white & coral red, so you get to lớn choose instead of being offered just a single màu sắc option.


Having the phone in hand revealed that even though the Xperia M4 Aqua’s body toàn thân is made from polycarbonate (plastic anyone?), it doesn"t look or feel cheap & is actually pretty robust. Despite being slightly thicker than the Xperia Z3, the M4 Aqua sits giaithuongtinhnguyen.vnfortably in the hand. While the side bezels are quite thin, as with the other Xperia phone models, the top and bottom bezels are quite large, which makes the phone look a bit longer than it actually is & also gives the impression of a smaller screen.

Sony"s signature round metal power nguồn button sits on the middle of the right side of the body, so you won’t have to reach too far khổng lồ turn the screen on. The volume rocker sits right below the nguồn button, và there’s also a dedicated camera button below the volume rocker. The dedicated camera button makes it easy lớn get shooting quickly as well as shoot underwater, and it’s nice lớn see that Sony did not skip on this feature despite the Xperia M4 Aqua being a mid-range model.


We mentioned shooting underwater because as we mentioned, the Xperia M4 Aqua is waterproof. The phone has an IP rating of 68, which means that it"s waterproof (in this case constant immersion beyond 1m) as well as being dustproof.The microSD và SIM card slots are all covered to prevent water from entering, và the best part about the Xperia M4 Aqua is that the micro-USB charging port và the tai nghe port are water resistant without having khổng lồ keep them covered with flaps.

Display và audio

The 5-inch IPS LCDdisplay has a resolution of 1,280 x 720 pixels and a px density of 293 pixels. It’s not as impressive as top-end models, but it’s still enough khổng lồ for apps and webpages to look reasonably sharp. Even so, you should take chú ý that there are phones that boast Full HD resolution at lower price points và that works against the Xperia M4 Aqua even though it has a nice kiến thiết ID and can withstand dirt and water.

As with most Sony displays (including their TV sets), the colors are quite accurate. But the Achilles heel for Sony smartphones still remains; the screen isn’t terribly bright và washes out when you’re outdoors.


Audio on the Xperia M4 Aqua giaithuongtinhnguyen.vnes from a single speaker located on the phone"s bottom, unlike the pricier Xperia Z series which giaithuongtinhnguyen.vne with stereo speakers. The speakers on the Xperia M4 Aqua are loud enough khổng lồ be heard from across a small room, though it does unfortunately sound quite tinny at higher volumes.

User Interface

The good news is that while the Sony Xperia M4 Aqua runs a customized version of apk 5.0 Lollipop, Sony has kept the customization khổng lồ a minimum. So besides the pre-loaded wallpapers and widgets, there aren"t many things that are different from vanilla Android. You can also download themes lớn change the look of the UI.

The bad news is that due khổng lồ the small 8GB internal storage capacity, with all the bloatware that giaithuongtinhnguyen.vnes pre-loaded with the phone, you don"t really have much space left. This essentially forces you khổng lồ purchase a microSD card to expand your storage. Out of the box you"re looking at a measly 1.21GB available for usage.

There are also "Small apps" similar khổng lồ Samsung"s Mini Apps, which launch small apps on your homescreen that look lượt thích widgets without having to access the full-fledged app itself. Opening the task manager will reveal a row of them at the bottom of the screen, though you can never disable them.
