An inexpensive and relatively simple smartphone, which stands out primarily for the presence of an NFC, as well as support for two SIM cards, which is reflected in the name. In addition, the appearance of the device is quite worthy of a mid-range model: the front panel is occupied by a 5 "display with a resolution of 1280x720. But under the display there is a modest 1.2 GHz processor (with 4 cores), supplemented by 1 GB of RAM, as well as a drive for only 8 GB (though supplemented by a card slot that supports microSDXC). Separately, it is worth mentioning the 8-megapixel main camera using a 1/3" sensor and capable of shooting video with a resolution of 1920x1080. The smartphone is controlled by the Windows Phone 8.1 operating system.
Solutions from Microsoft are a great alternative to Android smartphones, which have almost become monopolists in the modern market.
Windows
Microsoft Lumia 640 is a typical representative of the family of gadgets running on Windows. The classic tiled interface of the Windows Phone 8.1 operating system makes it easy to manage touch devices, which cannot be said about stationary computers. However there is one nuance that is associated with the limitations in applications for the Windows Mobile OS in general: some of them come out very slowly, and some are not at all tailored for this platform.
"Iron"
The hardware of the gadget consists of a Qualcomm Snapdragon 400 processor (4 cores at 1.2 GHz), 1 GB of RAM and 8 GB of internal memory. Hardware is time-tested and provides normal performance — games at medium settings will start without problems. The memory can be expanded up to 128 GB via microSD cards.
Screen
The 5-inch screen of a smartphone with HD resolution has one cool "bun", which is called ClearBlack. This is a special polarizing layer that provides visibility in bright light. Those. on a sunny day, it will not be difficult to see the picture on the display. At this resolution, the 2500 mAh battery provides 2 full days of work, which is worthy of respect.
Snapshots
The main 8-megapixel camera module with a maximum aperture of f / 2.2 takes quite suitable pictures of average quality. The front camera is worse — photos from it do not differ in a high degree of detail, which is not surprising, as for a 1-megapixel resolution.
Balance
Balanced characteristics make the smartphone a very attractive option to purchase. With only one "but" — if you are not held back by the Windows platform.
