The build of the smartphone is good especially when you compare it to other smartphones in the same price bracket. The curved back feels good and the dark blue color is attractive. The display has good viewing angles. The downside is that the colour reproduction isn't the best especially when you place the CanvasXpress 4G next to the Acer Liquid Z530. The UI on the phone is lightly skinned just like the ones we have seen on other Micromax smartphones. For everyday use the smartphone worked just fine. The call quality was good at both ends. There is a little audio leak from the earpiece at full volume, but I think this also be because the person I was speaking to was yelling. The speaker is positioned at the back of the phone, which isn't ideal if you place it face up on a table and listen to music. Most games run well, but graphically intensive games will suffer on the device.
The battery life : The smartphone lasted for about 7 hours in the GeekBench Battery test. The rear camera of the device is average and works if you want to post them on social networking sites.
If you are in the market to pick up a smartphone  under 7k, there are alot of options available that give the Micromax Canvas Xpressv 4G a run for its memory

FINAL VERDICT:  For a price of Rs. 6,599, the smartphone has 2GB of RAM, good viewing angles, 4G connectivity, and a good build. The camera on the smartphone is average at best, and the performance could have been better, especially when you have the likes of the Meizu M2 in the same price bracket. The audio output from the speaker is slightly soft, when you compare it to the competition, but it is loud when you use it as a loudspeaker during calls.
