Expert Rating:
![Ketaki Bhojnagarwala]()
Verdict
When you compare the Lumia 640 to its predecessor, the Lumia 630 (review), it`s apparent that Microsoft has worked on improving the specs of its affordable line-up. It’s priced at Rs 11,999, which is almost the same price the Lumia 630 was launched for last year, but manages to pack in a better display, camera and battery, among other upgrades. But what Microsoft hasn`t taken into consideration is the competition. At a time when Android manufacturers are vying to offer their smartphones at
Pros

What’s the same: design, hardware, software and connectivity

Looking at both smartphones side by side, the Lumia 640 looks like a shrunken version of its bigger sibling. Design-wise, they're both identical. The front of the smartphone features the secondary camera, Microsoft logo, earpiece and sensors above the display. The chin is bare except for the primary microphone, since the phone incorporates a virtual navigation bar on the screen. The port and button placement is a standard affair, with the 3.5mm audio jack on top, the micro-USB port at the bottom and the volume rocker and power button on the right.

What’s different: display, cameras, battery life
+
The Lumia 640 and Lumia 640 XL both feature HD resolution screens, but on the latter’s large 5.7-inch display, this translated into a lower pixel density, and subsequently compromised sharpness. On the Lumia 640’s smaller 5-inch display, you get a decent pixel density of 294ppi. The differences are clearly visible, with the 640's display looking much sharper than that on the 640 XL. The screen responsiveness, viewing angles and sunlight legibility however, are on par with the Lumia 640 XL. Both displays offer ClearBlack technology, Gorilla Glass 3 protection and the Glance Screen feature.
