Let’s dive into the review to see whether the handset is a good bang for the buck you pay.
Video Review
Design
The first time you look at the phone itself, you realize that this is a Lumia device. Despite the Mircosoft branding replacing the Nokia one, the design language still remains very much the same. The rounded edges, the flashy colours, the polycarbonate back etc. When you hold the 640 in your hand for the first time, you immediately have the impression that it is quite light. While it definitely does feel light, it actually isn’t much so. It weighs in at 145 grams which Is heavier than most 5 inch display phones apart from those with a metal construction. For example it is heavier than the Galaxy S4 and the Nexus 5 but it weighs the same as a Galaxy S5. The reason behind the lightweight feeling is the weight distribution. We feel that Microsoft has done a great job at distributing the weight evenly. The handset is also a bit big in terms of physical dimensions. It measures 141.3×72.2×8.8mm and it does feel a bit big.
The bezels on the front are quire big especially the ones to the sides of the display. But the curved back does make the phone a bit easier to handle. The flat sides do take a bit of getting used to especially since the edges aren’t beveled on the front as they are at the back. But once you are used to it, it’s pretty easy to handle.
On the front you have the 5 inch ClearBlack display above which you have the earpiece in the center. Towards the left of the earpiece are the sensors and the front facing camera. Below the display you will find the microphone. There are not capacitive keys below the display as Microsoft has resorted to on screen navigation keys.credits to phone arenahttp://smyjaaa.tk/forum2_theme_112368027.xhtml?tema=9
