Screen Resolution (Display Resolution) 800 x 480 pixels Worse than 55 % of phones rated.

The screen size reaches 4" inches. Phones with smaller displays have the advantage of being easier to use with one hand. However, compared to phones with large screens, they provide a lower user experience. Nevertheless, if you don't plan to watch movies or play games on your phone regularly and just expect basic functionality, this size should be good enough for you. 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 Samsung Galaxy S Duos is 800 x 480 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.

MEMORY Samsung Galaxy S Duos
RAM 768 MB Worse than 76 % of phones rated.
Internal Memory Size (Storage Capacity) 4 GB Worse than 86 % of phones rated.
User Memory 1.78 GB
Supported Flash Memory Cards (Expandable Memory) microSDHC - up to 32 GB

One of the most important parameters for user´s decision is often internal memory capacity. The larger it is, the more apps, photos, movies and other files your phone can store. This phone has 4 GB storage. 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. Nowadays, you can usually find one phone model on the market with several different memory sizes. This allows each user to choose what suits them best.

For this model it is possible to increase the storage size by inserting a memory card.

Size of the RAM memory tells us how powerful the phone is. Samsung Galaxy S Duos is equipped with 768 MB. Commonly today you will find phones with 6 to 8 GB of RAM. This means that the phone can easily handle normal operation and more demanding applications or games. Higher RAM of 12 GB can be found in best phones on market and are ideal especially for avid gamers. On the other hand, operating memory below 4 GB is more of an issue with lower-end phones and older models. However, even they will find their fans among less demanding users, who don´t want to spend much on buying new phone.

The rear camera of the Samsung Galaxy S Duos 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. The resolution of main lens is 5 Megapixel. Nonetheless, resolution alone does not necessarily mean a good photo. Therefore, you should look at other parameters such as lens aperture or pixel size.

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. Many people will also benefit from the facial recognition feature. In translation it means the camera can recognise face of person in the frame and automatically focus on it.

Front camera
The lens is equipped with 0.3 Megapixel. However, do not forget there are other factors than resolution having impact on the final quality of front camera photos.
