Cubot J20 is a beautiful device that was officially announced in March 2023. It adopts a modern design and includes multiple great features that can be used by all users.

The Cubot J20 is also known as the device model series Unknown, which must be unique so that users can easily find support online. Sometimes using only the main device name can make it difficult for several users to find the right support. The weight of Cubot J20 is 143 grams and the body dimensions are 138 x 65 x 10.8 mm. These dimensions are ideal for modern devices. Lastly, the device is available in Black, Green color options. However, the availability of color options may vary by country and market. Some color options may only be available for a limited time or during specific events.

Build Quality

The Cubot J20 features a body made of plastic, which is a common material used in entry to mid-level devices. While plastic is not a bad material in this modern era, it can feel cheap, be easily scratched, and lacks the solid feel of other materials. For flagship devices in higher price ranges, plastic bodies are generally not used, so if you find this material on the latest flagship device, it can be seen as a disadvantage for users.

Screen & User Navigation

The display screen configuration is a crucial factor for the user experience, and in the case of the Cubot J20, the screen setup is ideal, featuring a resolution of 480 x 854 pixels combined with a screen size of 4.0". Additionally, the display screen also has several other configurations, including ~245 ppi density.

Another important factor to consider for the display screen is the display panel hardware. Good display panel hardware will greatly enhance the user's experience. The Cubot J20 uses the very common display panel hardware, IPS LCD, which is suitable for entry-level to mid-level devices. However, it is not recommended for flagship devices with higher prices unless there is a special screen technology innovation implemented.

The physical buttons on the Cubot J20 are positioned and designed for easy use, with clear functions such as powering up the device or adjusting the volume level.

CPU & GPU Performance

The processor and graphics hardware are vital components for any device, as they handle the majority of the software tasks and rendering graphics. In the case of the Cubot J20, it utilizes the MediaTek MT6739WA for the CPU and PowerVR GE8100 for the GPU. But, the question is: are they good enough?

The answer is yes. This CPU and GPU combination is capable of handling multiple tasks on the device, including running games, opening apps, and rendering 3D images at their maximal limit. Users can expect good performance from these hardware components.


In addition to CPU and GPU hardware, memory hardware is also a very important sector for ensuring the best user experience when using a device for multiple purposes. The memory sector includes the RAM capacity, internal memory storage, and support for external expansion memory. So, is Cubot J20 good enough in terms of memory performance?

When we look at the memory combination specification, we can see that Cubot J20 has 2GB of RAM and 16GB of internal memory storage capacity. The user can get more storage on this device because Cubot J20 does support external memory expansion using MicroSDXC.

Therefore, does Cubot J20 have good memory performance? Based on the specifications, it is good enough for any modern use, but it also depends on the user's perspective and needs.


Just like other modern smart devices available today, Cubot J20 has a camera feature that enhances the user's experience. The main/rear camera feature of Cubot J20 has a Single Setup camera configuration feature.
