Samsung Galaxy Z Fold3 5G Review

The third attempt of the South Korean company to provoke the interest of the mass consumer to the new format of the smartphone is called Samsung Galaxy Z Fold3 5G. It is a folding tablet. This generation is not cheaper, but there are improvements that give another reason to make the transition to it.


The design of the Samsung Galaxy Z Fold3 5G has remained unchanged compared to the previous generation. However, the technical characteristics have been improved. The smartphone is thinner and lighter. The huge area of ​​the almost square display has a diagonal of 7.6 inches and is one of the factors that attracts the most users.

You should know that the dimensions of the model do not allow you to unfold it with one hand, as well as to fold it. You need to at least help yourself with the finger of the other hand. Its body is made of modern materials and the panel is made of strong glass of the latest generation Corning Gorilla Glass Victus. The side frame is made of brushed aluminum and creates a pleasant impression.

Due to the presence of a special coating, the surface is difficult to collect traces of prints. So Samsung Galaxy Z Fold3 5G always looks representative.

On the market you will find the model in three colors - black, silver and green. Its housing is protected against moisture according to the IPX8 standard. In other words, you can immerse the Samsung Galaxy Z Fold3 5G to a depth of up to a meter and a half for a maximum of half an hour.


The smartphone is equipped with a flexible main AMOLED display with a diagonal of 7.6 inches. It has a resolution of 1768 x 2208 and has physical dimensions of 12 x 15 cm. The pixel density per inch is high. The screen is updated with a frequency of 120 Hz, which is very good and speaks of the level of user satisfaction.

The external display, in turn, is AMOLED, covered with protective glass and measuring 55 x 144 mm. Its form does not predispose to convenient reading of textual information. It has rather an ancillary function.


Samsung Galaxy Z Fold3 5G is based on an 8-core single-chip Qualcomm Snapdragon 888 5G system. The graphics processor is GPU Adreno 660. You will find two modifications on the market - with 12 GB of RAM and 256 or 512 GB of storage. UFS 3.1. No memory card space is provided. Carefully consider your needs for memory space, given the inability to expand it later.

Qualcomm Snapdragon 888 can be said to be one of the most powerful mobile platforms in 2021. It is made of 5 nm process technology. Thus, Samsung Galaxy Z Fold3 5G demonstrated high test results. Among the disadvantages is the serious energy consumption. You will enjoy smooth operation using all kinds of applications and games.

The smartphone works with Android 11 operating system and OneUI 3.1.1 company interface. You can switch between the small screen and the big screen without closing the programs.


Samsung Galaxy Z Fold3 5G has a triple rear camera, optical stabilization, a module with double optical zoom and wide-angle with a visibility of 123 degrees to accommodate more objects and people. In general, the set of cameras remains unchanged from the one we know in the Galaxy Z Fold2.

In portrait mode, it is super convenient to create a selfie on the main camera, looking at the small screen. This is an advantage typical of folding smartphones.

Autonomous work

Samsung Galaxy Z Fold3 5G has a built-in battery with a fairly large capacity. However, the device continues to demonstrate less autonomous operation than desired. It is difficult to compete with market leaders on this indicator.

The smartphone has a battery with a capacity of 4400 mAh, which provides up to 16 hours of continuous reading from the screen or watching videos. In 3D game mode, you will need the charger after about 6 hours.

It takes 1 hour and 50 minutes to fully charge the battery from 0 to 100%. Support for wireless charging is provided, as well as technology for reversible charging of other devices. Thus, Samsung Galaxy Z Fold3 5G can act as an external battery for watches, headphones and more.


Samsung Galaxy Z Fold3 5G is not a phone for everyone. Its price contributes to this to some extent, but also to the consumer's willingness to change their habits. The smartphone definitely offers something that many others do not. Its advanced functions and workmanship are inviting. The body is stronger, there is now protection against moisture and dust, a non-standard camera is used in the screen and a function for working with the stylus has been added.

5G support is also a reason to consider the Samsung Galaxy Z Fold3 5G when considering buying a new smartphone. We also see an improvement in productivity. What remains at the same level before is the autonomous operation, sound quality, screens and cameras.
