The screen size reaches 5.7" inches. With a large display, phone offers a great experience for watching videos, playing games and reading. The best phones today are 6.5'' or more. They have the advantage of a large display area that allows you to see more content than with conventional display sizes. LCD displays are currently taking a back seat. This is mainly due to higher power consumption. In addition, they have the disadvantage of lower colour contrast, which can be reflected e.g. in the resulting photos. On the other hand, phones with LCD displays are in general cheaper than those with OLED technology.
Display Resolution of Microsoft Lumia 640 XL Dual SIM is 1280 x 720 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px. If you want a perfect picture, focus on pixel density in addition to resolution. This number indicates how sharp the image will be. Best phones today have a display fineness of 450 ppi or higher, but the today´s average is around 350-400 ppi. That should be enough for you to enjoy a fine and sharp image. This model has a pixel density of 259 ppi.
|PROCESSOR Microsoft Lumia 640 XL Dual SIM|
|Processor Type (CPU)||Qualcomm Snapdragon 400|
|Clock Speed||1.2 GHz||Worse than 65 % of phones rated.|
|Processor Core Qty||Quad-core||Worse than 55 % of phones rated.|
The processor type of the Microsoft Lumia 640 XL Dual SIM is Qualcomm Snapdragon 400. The number of processor cores is 4. It is a number of cores that plays an important role in evaluating the performance of phone as it is responsible for computing operations. Smartphones already commonly have a core count of around 4 to 8. Multi-core processors can perform better and reduce the processing time of a request to a minimum, which is reflected in the responsiveness of the phone, e.g. in the speed of opening applications. Microsoft Lumia 640 XL Dual SIM is provided with processor´s frequency of 1.2 GHz. Normally today you will find this value between 1.8 and 2.8 GHz, and the higher the number, the faster the response of the phone. The processor frequency will thus be one of the important parameters if you are looking for a phone capable of managing several requests at once without major problems.Show more
|MEMORY Microsoft Lumia 640 XL Dual SIM|
|RAM||1 GB||Worse than 60 % of phones rated.|
|Internal Memory Size (Storage Capacity)||8 GB||Worse than 71 % of phones rated.|
|Supported Flash Memory Cards (Expandable Memory)||microSDHC, microSDXC - up to 128 GB|
The phone is provided with an internal memory of 8 GB. Internal storage capacity is often a key parameter, as it determines how many files, photos, apps and more your phone can store. This memory capacity is ideal for those who have a few basic apps and a few dozen photos on their phone. If you don't expect to use your phone to play games or need to store high-resolution photos, this size should be sufficient. There is almost no probability you're likely to see this low capacity on new smartphones. The standard memory today is around 64 and 128 GB. The best phones have internal memory of 256 GB or more. Fortunately, manufacturers nowadays think of all users and therefore offer phone models with different memory sizes so that everyone can choose what suits them.
In addition, if you need more memory, this model offers the option of inserting a memory card to increase the storage size.
Operating memory significantly affects the performance of the entire phone. Microsoft Lumia 640 XL Dual SIM has an operating memory of 1 GB. Phones with less than 4 GB of RAM are better suited for undemanding users who use phone more for basic needs and some essential applications only. But if you are a heavy user, reach for at least 6 to 8 GB of RAM, which is the standard today, or 12 GB for the really demanding ones.

The rear camera of the Microsoft Lumia 640 XL Dual SIM has only one lens. Single lens is more typical for older phones or lower-end phones with lower quality cameras. The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 13 Megapixel. However, if you are looking for perfect photos, in addition to resolution, don't forget to focus on at other parameters such as lens aperture or pixel size. Luminance is one of the main factors determining the quality of a photograph. Commonly today, this value ranges between F/1.8 and F/2.2. However, best photomobiles have an aperture of up to F/1.2. Value indicates how much light passes through the sensor and the lower it is, the better the quality of the photos. Main lens here is equipped with F/2.0.
Digital zoom in this case offers zooming up to 4x. Of course, the higher the lens value, the more distant object can be zoomed in. Nonetheless, the disadvantage of digital zoom is that the quality and sharpness of photo deteriorates when using it.
The front camera of phone Microsoft Lumia 640 XL Dual SIM has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of main lens reaches 5 Megapixel. Again, it should be noted that resolution is not the only factor affecting the quality of the front camera photo.
