Hardware
| Chipset <strong>Chipset</strong> is a group of integrated circuits designed to perform one or a more dedicated functions, often with real time computing constraints, Popular smartphones are equipped with more advanced embedded chipsets that can do many different tasks depending on their programming. | Mediatek MT6739W (28 nm) |
| CPU <strong>CPU</strong> (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone. | Quad-core 1.5 GHz Cortex-A53 |
| GPU <strong>GPU</strong> (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion. | PowerVR GE8100 |
| RAM (Memory) <strong>RAM</strong> (Random Access Memory) is a type of computer memory that can be accessed randomly, any byte of memory can be accessed without touching the preceding bytes that allows information to be stored and accessed quickly from random locations. RAM is the most common type of memory found in computer systems, smartphones, tablets and other electronic devices. | 2GB, 3GB |
| Internal Storage <strong>Internal Storage</strong> is a data storage space (flash memory) mostly used in smartphones, tablets and other electronic devices where operating system, apps, music, photos, videos, files and other user data Is stored. | 32 GB,64 GB |
| Card Slot <strong>Memory Card Slot</strong> is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras. | Yes |
Rear Camera
| Rear Camera | Dual |
| Primary <strong>Camera</strong> is able to capture photographs and usually videos, The most important characteristics of a camera are the resolution (measured in megapixels), lens focus type (fixed or automatic), higher megapixel cameras are known to capture higher quality photos, but not always a good measurement of the photos quality. | 13 MP, f/1.9 |
| Macro | 2 MP, f/2.4 |
| Video | 1080p@30fps |
| Camera Features | LED flash |
| Flash <strong>Flash Light => </strong> There is commonly two types of flash lights are used in camera mobile phones, LED Flash (LED flash offers lower power consumption with drive circuitry that takes up very little room, LEDs can be strobed faster than any other light source), Xenon Flash (xenon flash produces an extremely intense full-spectrum white light for a very short duration) | Yes, LED |
Front Camera
| Camera | 5 MP, f/2.0 |
Software
| Operating System <strong>OS => </strong> Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device. | Android 10, One UI 2.0 |
Battery
| Capacity <strong>Battery Capacity</strong> is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain conditions. | 5,000 mAh |
Connectivity
| Bluetooth <strong>Bluetooth</strong> is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices. | 5.1, A2DP, LE |
| Infrared <strong>Infrared</strong> connectivity is an old wireless technology used to connect two electronic devices. It uses a beam of infrared light to transmit information and so requires direct line of sight and operates only at close range. | |
| Wi-fi <strong>Wi-Fi</strong> is a popular wireless networking technology using radio waves to provide high-speed network connections that allows devices to communicate without cords or cables, Wi-Fi is increasingly becoming the preferred mode of internet connectivity all over the world. | Wi-Fi 802.11 b/g/n/ac, Wi-Fi Direct |
| Wi-fi Hotspot | |
| USB | microUSB 2.0 |
| GPS <strong>GPS</strong> The Global Positioning System is a satellite-based radio navigation system, GPS permits users to determine their position, velocity and the time 24 hours a day, in all weather, anywhere in the world, In order to locate your position, your device or GPS receiver must have a clear view of the sky. | Yes |
| NFC <strong>NFC</strong> (Near field communication) is a set of standards for smartphones and similar devices to establish peer-to-peer radio communications with each other by touching them together or bringing them into proximity, usually no more than a few inches. |
