The X550 cube looks very urban and would attract young students who are looking at a budget touchscreen device. The phone has a smooth matte finish across the body with a 3.2 resistive touchscreen dominating the front. There is a single button (in shiny purple) on the front under the display that functions as the back button and on the right side are the volume keys and camera shutter key. At the base is a microUSB port and a 3.5 mm audio port. The power/hold button is at the top, and its a bit too small and poorly nested in the body for comfortable use.
Coming to the user-interface, the home-screen has animated wallpapers that are touch sensitive almost like the ones found on Android devices. There is a quick application launcher at the bottom, but it has a few select applications to choose from. At the bottom itself is a menu icon and a back icon for easy navigation. The main menu area is the actual cube interface by which the phones name has been inspired.
A single touch on the icon and the 4 menu pages show up in a cube format which can be rotated easily to quickly move through menu pages. The main menu can also be navigated by pressing on the display and moving the finger left or right. This way it the navigation occurs in a 3D wall motion.
The interesting part is that the UI on the whole is very zippy and quick to respond. The only issue we had was with the lock screen as it requires the user to move the lock slider upto 75% of the display to unlock the screen which is a pain.
Typing an SMS is another major issue we faced. The onscreen QWERTY keyboard is one of the things that cripples the value of the phone. First of all the onscreen keys are too small to comfortably use with fingers and secondly, instead of the standard 3 row QWERTY keyboard, the phone divides the keyboard in 4 rows, thus making it extremely difficult to use.
Even for a new user, it would take some time to get used to the keyboard. The handwriting recognition worked fine, but then it affects the input speed as it recognised one character at a time and not whole words.
In terms of multimedia features, the X550 Cube has FM Radio with recording and the phone was able to catch all radio stations in auto search with good clarity. The recording worked great as well and provided options to record audio in high quality .wav format.
The MP3 player worked great as well, though it did take a few minutes to get all songs on the memory card in first scan. The X550 comes with a basic 2 MP camera and lacks any flash. The camera does provide various settings such as banding, effects, white balance, night mode etc.
The volume output from external and in-ear speakers from the phone is extremely loud and clear, though at maximum volume the loudspeaker started blaring. The phone also has Bluetooth with A2DP and comes loaded with applications such as Opera, Nimbuzz and Snaptu.
Overall, the Micromax X550 Cube is a great entry-level touchscreen phone. However, its quirks in respect to the onscreenkeypad, poor camera and the lock screen makes it loose out in terms of ease of usage and features.
At its price of Rs 5,999, the phone faces stiff competition from the Fly E145 which sports a similar 3.2 display, 2MP camera, handwriting recognition alongwith dual SIM capabilities with a motion sensor added in the mix and comes at Rs 5,499.
