The market area that belongs to mid-range smartphones offers a whole bunch of devices, so that every customer that doesn’t aim for flagships has a wide area of handsets to choose from. Today, I’m going to review a mid-ranger that comes from Microsoft (it’s good-bye Nokia for now), the Lumia 640, a highly capable smartphone that holds some tempting features under its hood, such as an excellent 5 inches ClearBlack display, a (somehow dated) Snapdragon 400 chipset, optional dual-SIM support and LTE, an above average 8 MP camera, a 2,500 mAh battery and more. If you fancy Windows Phone or simply want to try something different than Android, check it out in the following review and see if it’s fit to suit your needs.

Inside its retail box, the Lumia 640 comes accompanied by its charger and a microUSB cable used for making data transfers and re-charging your unit. Unfortunately, that’s about it, there are no headphones offered and that’s a pity to be honest.

In terms of appearance, the Lumia 640 stands at 141.3 x 72.2 x 8.8 mm and has a weight of 145 grams. The phone could have been more compact, considering that it lacks hardware keys. Anyways, it looks pretty simple, having a rectangular body with rounded edges and a curved back, being similar to some other Lumia siblings, so its look will seem very familiar. The phone is made from polycarbonate and has removable back covers that come with a glossy or a matte finish, depending on the color you pick. The build quality seems to be solid and reliable, which is a quality that actually runs in the Lumia family.

On its frontal side, the Lumia 640 holds a 5 inches IPS LCD capacitive touchscreen which offers a resolution of 1280 x 720 pixels and has a pixel density of 294 ppi. For protection, the ClearBlack display relies on Corning’s Gorilla Glass 3. The handset offers a very good image quality, with nice colors, great contrast and wide viewing angles. The sunlight legibility is decent. For improving the screen quality, you can adjust the temperature, saturation or brightness settings.

At the software department, the Lumia 640 offers support for Windows Phone 8.1, the 2nd update, and also features the Lumia Denim package. Microsoft has been working on their Windows 10 OS, which will be available for the handset as soon as it’s ready to be officially released.
If you’re familiar with the platform, my guess is that you’ll be right at home when browsing through the Lumia 640; if not, it shouldn’t take long before getting accustomed to it. Its minimalist interface consists in the lockscreen, which displays the time, date and the notifications you’ve configured to appear here. Beyond the lockscreen is the Start screen, which holds resizable tiles and can be customized by adding a background image. Not all of the live tiles can become transparent for revealing your chosen picture, but the overall look is pretty cool and interesting, nevertheless.
The notifications and quick toggles are held by the Action Center, which is accessed when you swipe down from the top of the screen. Also here is a Settings shortcut and a key for clearing all your notifications. You can have up to four quick toggles from a total of 13 and order them as you wish.
Microsoft has also been busy with creating a personal assistant, Cortana, which is capable of taking voice commands, make suggestions, search places or other info relevant to you, plan trips and more. It can even tell tokes or sing.

Inside its hardware package, the Lumia 640 holds a Qualcomm Snapdragon 400 chipset, having a quad-core 1.2 GHz Cortex-A7 processor, Adreno 305 GPU, 1 GB of RAM and 8 GB of internal storage, which can be expanded with a microSD card of up to 128 GB. The handset isn’t designed for power-users, but will deliver a great user experience if used for daily tasks and won’t be bothering you with any lagging or freezing at any time.

When it comes to connectivity, the Microsoft Lumia 640 comes in three versions: one with dual-SIM support and LTE, dual-SIM without LTE or single SIM with LTE. All of them feature quad-band 2G, 3G, Wi-Fi b/g/n with DLNA and the Hotspot functionality, Bluetooth 4.0 with A2DP, NFC and microUSB 2.0.

For taking pictures, the Lumia 640 comes packed with an 8 megapixels snapper with autofocus, which captures stills with a maximum resolution of 3264 x 2448 pixels and is helped by a LED flash when there’s not enough light. The photos delivered will reveal a pleasant image quality, with beautiful colors, fine contrast and a good amount of resolved detail.
The video camera is also a decent performer and will produce some smooth 1080p videos @30 fps.
For making video calls, you have a front-facing 1 MP camera.

Some other useful things that are offered by the Lumia 640 are Internet Explorer 11, which offers a satisfying browsing experience, the Office Suite for managing document files, a GPS receiver with A-GPS and GLONASS support, HERE Maps and HERE Drive+ for getting around (the latter features voice-guided navigation), an FM Radio with RDS support and more.

The Microsoft Lumia 640 is powered by a 2,500 mAh battery and will stay alive for three days if you use your handset moderately.
