Cubot J20 specifications

Body

The weight of Cubot J20 is about 5.04 oz with battery, which is average compared to most of the smartphones with same size. The dimensions of this Cubot smartphone are average (5.43 x 2.56 x 0.43 inch). Smaller smartphones are more compact and easier to carry around, but they may have smaller displays that can be harder to read and interact with. A Nano SIM is a small (12.3 x 8.8 x 0.67 mm) chipcard that is used in smartphones as a subscriber identity module (SIM) for connecting to a cellular network.

System

The Cubot J20 comes with Android OS v12.0 Go Edition out of the box, but it is upgradable to the next OS. Android is closely integrated with various Google services, such as Google Maps, Gmail, and Google Drive, which makes it easy for users to access and manage their data across multiple devices. The J20 has a Mediatek MT6739WA CPU. This mid-range, quad-core CPU is capable of delivering fast and efficient performance for a wide range of tasks.

The J20 utilizes PowerVR GE8100 GPU. A GPU (Graphics Processing Unit) is a specialized chip that is primarily designed to handle and accelerate the processing of graphics and visual data. It is responsible for rendering images, videos, and animations on a smartphone screen. PowerVR GPUs are a popular choice for mobile device manufacturers, and are known for their power efficiency and strong performance. We use AnTuTu app to measure general processing performance. AnTuTu Benchmark is the most popular benchmark app for Android phones.

Display

The 4 inch phone comes with IPS display. The IPS display provides enhanced features, such as optimal viewing angles, color accuracy, invariable color reproduction and better power consumption. Smaller smartphones are generally more compact and easier to handle. The size of the screen is measured diagonally, from corner to corner. A larger screen typically requires more power to illuminate, which can impact battery life. The display of Cubot J20 is multitouch capable. Multitouch technology enables the device's touchscreen to detect and interpret multiple touch points on the screen simultaneously.

Memory

With 2 GB of RAM, a smartphone can run multiple apps simultaneously without experiencing any significant lag or slow performance. Having more RAM alone does not necessarily guarantee better performance, and other factors such as the processor and storage speed can also impact overall performance. 32 GB of internal storage is generally considered to be the minimum amount of storage you would want in a smartphone. The J20 has only 16 GB of internal storage. The internal storage of the J20 (16 GB) can be expanded with a compatible microSD card. A microSD card is a type of small, removable flash memory card used to store digital information.

Camera

The J20 offers only a single-camera setup. The single camera can still be sufficient for many smartphone users, depending on their photography needs and preferences. The main camera of the J20 is equipped with autofocus. An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. Very few Android cameras come without autofocus. The J20 does not have optical image stabilization (OIS). OIS technology is more commonly found in higher-end smartphones and is designed to reduce camera shake and blur, resulting in sharper and clearer images and videos.

Connectivity

The Cubot J20 supports 4G/LTE networks. 4G stands for fourth-generation mobile networks, which are wireless networks that provide faster data transfer speeds and greater network capacity than previous 3G networks. To connect to a Wi-Fi network on the Cubot J20, you simply need to go to the Wi-Fi settings on the device, select the network you want to connect to, and enter the password. With Bluetooth connectivity, you can connect your J20 smartphone to a wide range of Bluetooth-enabled devices, such as headphones, speakers, smartwatches, fitness trackers, and more.

This phone has a built-in GPS. GPS is a highly accurate navigation system using signals from satellites to determine a location on the Earth's surface, irrespective of weather conditions. Most phones have a GPS unit on board. The J20 isn't NFC (Near Field Communication) capable. NFC is not essential for basic phone functionality, but it can be useful for a variety of tasks and features. The J20 phone has built-in FM radio receiver. FM radio allows users to tune in to local radio stations and listen to live broadcasts, news, music, and other content.

The J20 has a microUSB port. MicroUSB is a type of USB connector that was commonly used on older smartphones, tablets, and other mobile devices. The J20 smartphone has a 3.5 mm headphone jack. A 3.5 mm headphone jack is a small round port, that allows you to connect wired headphones or earphones to the device.

Battery

The Li-Po 2350 mAh battery gives the smartphone a good battery backup. The lithium polymer (Li-Po) battery is a thin, light-weight, rechargeable battery. No periodic discharge is needed and charging can be done at random. The battery of J20 is removable. You can simply buy a new piece from the open market and interchange it easily by yourself.

Features

Smartphones today come with a wealth of sensors to facilitate a better user experience. The accelerometer provides information about the smartphone's movement in three axes: X (horizontal), Y (vertical), and Z (depth). The ambient light sensor detects the level of ambient light in the surrounding environment. The main purpose of a light sensor in a smartphone is to automatically adjust the brightness of the device's display. The Dual SIM capability of Cubot J20 phone is ideal for businesses wishing to provide staff with a mobile device that can offer separate numbers and bills for both personal and business use.
