Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) Specifications, Tests and Review

The screen size reaches 5.3" inches. Smaller phone displays are not necessarily a disadvantage. They are easier to use with one hand. However, displays of these sizes don't provide the same experience when watching videos or playing games, so they're better suited for less demanding users. It means, if you're a basic user and you don't expect to use your phone for activities like watching videos or playing games on regular basis, this size is perfectly adequate. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.

Display Resolution of Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) is 2560 x 1440 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.

The processor type of the Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) is Qualcomm Snapdragon 835. The number of processor cores is 8. 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. Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) is provided with processor´s frequency of 2.5 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.

The phone is provided with an internal memory of 64 GB. Internal storage capacity is often a key parameter, as it determines how many files, photos, apps and more your phone can store. If you expect to store low thousands of photos, some songs, few movies or games on your phone, then you can easily get by with a medium memory size. Phones with this size of memory also has the advantage of a lower purchase price. If you don't plan to use your phone for 4K video creation and storage, using hundreds of apps etc. then you should feel free to go with this memory size. 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. Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) has an operating memory of LPDDR4X SDRAM - 4 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 Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) is equipped with 2 lenses. A larger number of lenses usually results in better quality photo, as each lens is designed differently: usually as a macro lens, telephoto lens or wide-angle lens. Macro lens is used for great close-ups, telephoto lens is designed for capturing objects in the distance as it often has an optical zoom, and wide-angle lens will take great landscape photos where you need a larger field of view. 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. An undeniable advantage is the optical image stabilisation, which makes image significantly more stable without any loss in quality. Cheaper phone models are equipped with electronic stabilisation, which has a negative effect on the resulting image quality.

Second camera
The resolution reaches size of 13 Megapixel.

Front camera
The front camera of phone Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) has one lens. This number of lenses is standard on most smartphones nowadays. The main front lens is designed as a Wide-angle lens. The resolution of main lens reaches 13 Megapixel. Again, it should be noted that resolution is not the only factor affecting the quality of the front camera photo. The aperture of main lens is F/2.0.

The battery size of Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) is 3090 mAh. Nevertheless, battery capacity is not the only factor that affects the phone's battery life. For example - the size of the display, the performance of the processor, the use of data functions and, of course, the intensity of use of phone in general all have a significant impact on battery life. Standard for most smartphones today is a battery capacity of around 4500 to 5000 mAH. Phones with this battery size usually guarantee a phone life of at least 1 day. Older or cheaper smartphone models can then reach battery capacities typically around 2500 mAH and below. With this capacity, you may find that if you use your phone heavily, you may need to recharge your phone during the day.

Nokia 8 (Dual-SIM (SIM1 and SIM2/MicroSD slots)) supports 4G. 4G connectivity is still common today, although the latest phones already have 5G connectivity. 3G connectivity is now more of a thing of past and can only be found on older models. The phone's operating system is Android 7.1.1 Nougat.

The NFC function will please all fans of contactless mobile payments. In addition, you can also use function in the context of connectivity, for example, to unlock doors or load menus in restaurants. Bluetooth 5.0 makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
