Upper and lower edges slightly thicker even without external speakers or physical joystick on it. Back keys, Windows and search on this phone is placed in the screen, makes it look thicker rim section.
Machine still owns polycarbonate body design and familiar squarish design of the Lumia phones. Because the machine is cheap, plastic polycarbonate material on this phone is not as beautiful as the high-end Lumia and easier to pick up fingerprints, especially on the black version we used in reviews. Perhaps the white version, the problem will help pick up fingerprints more visible. Lumia 550 is available in two color options are black and white.
But design and form thick but slightly rough feel in return the machine to make sure when handling. Removable chassis to replace the battery, insert the memory card and SIM. This shell is quite thick slabs, tiles snugly against the body should not be creaking when his fingers. For details on the edges and the back, only one point worth noting is the power button located on the right edge slightly lower, if this key is set up, the press will be a little more easier. The other did nothing worth complaining.
Overall, the design of the Lumia 550 have nothing new, the same as the Lumia still cheap from the longer belong to Nokia. However, the use of lasts old design has advantages that will help Microsoft reduce costs for design and manufacturing to invest more other components such as the display and camera.

Software and performance
Lumia 550 is one of the few phones pre-installed version of Windows 10 Mobile, platform marked major turning point in Microsoft’s strategy: unified device platforms on the same operating system. Although the core of the Windows 10 software on Lumia 550 with Windows 10 on the same computer or laptop and the user interface is designed for mobile, not much different from Windows Phone 8.1.
If used Windows Phone 8, you will see the familiar Windows 10 Mobile. Two main screen displays a list Live Tille and applications substantially unaltered, interface settings are rearranged and the notification bar / quick access now changing in the same direction with Android offers many options than. Glance Screen screen displays information (date and time) and lock screen notifications are also present on this phone.
A number of Windows 10 on a computer can be used on the Lumia 550 as the new Edge browser, mail client and calendar Outlook, Office, Skype, maps … But due to equipment is cheap and weak configurations, Lumia 550 is not equipped feature phone turns into Continuum computer and unlock the phone by eye Hello.
Regarding applications, unified platform Windows 10 targeted for devices Microsoft is to erase the distance applications with competitive platforms, enabling developers to create applications on shared all computers, tablets and phones. However, at present the new Microsoft is at the starting point of this goal, the number of applications is still far behind Android and iOS.
Regarding performance, the Lumia 550 is relatively low ownership configuration: 1.1GHz quad-core Snapdragon 210 and 1GB RAM. With this configuration, the machine remains stable handling basic tasks. However, the problem is more noticeable Windows 10 Mobile itself has not yet been finalized, exists the small errors during use. Machine occasionally suffer shock, mild or even sometimes feature does not work (such as collapsible screen rotation lock) to restart a new device running smoothly.
Internal memory of the machine is only 8GB, which own Windows 10 systems and applications that consume more than 5GB, remaining close to 3GB for user space. However, the good news is you can move applications and games on the memory card.
About the battery, we first try of the battery meter in the ability to watch movies. The results showed that the 2100 mAh battery of the Lumia 550 helps the machine is 4 hours 55 minutes office. This is the result inadequate when compared with the same price range Android, may be enough to help the machine used was a day at high intensity.
Lumia 550’s camera is equipped with a modest resolution, 5MP main camera and 2MP to other camera. However, the default camera app supports many custom: ISO, white balance, offsetting morning, about the focus and shutter speed. In addition, the machine also features video capture 3 seconds (Living Image) like the iPhone and Photo HDR (Rich Capture).
When shooting outdoors, relatively fast shutter speed and image quality of the Lumia 550 is not so bad, detail and sharpness in the average, relatively realistic colors though in some cases, white balance haunted gold. Overall, 550 photos from sufficient if demand is only share pictures on social networks and not too highly photographic activities. Low light shots are not good quality, light color, low brightness.
Overall, the biggest highlights in the Lumia 550 is a high-brightness screen, beautiful colors, good viewing angles with the camera steady shooting outdoors. The rest of the machine have nothing attractive: the old design, experience and performance software are not yet complete, the battery life on average. Lumia 550 will be difficult to attract more buyers and compete with Android phones in the same price range if not soon complete Microsoft operating systems Windows 10 Mobile or attractive pricing policy.
