Resistive Touchscreen (Resistive touchscreens contain two layer of conductive material with a very small gap between them which acts as a resistance), Capacitive touchscreen (Capacitive touchscreen technology consists of a layer of glass coated with a transparent conductor)||Capacitive Touch screen|
|Protection <strong>Display Protection =></strong> The widely used and best display protection is Gorilla Glass. Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use, it is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind.||Yes, Corning Gorilla Glass 3|
|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.||Exynos 9611 (10nm)|
|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.||Octa-core (4x2.3 GHz Cortex-A73 & 4x1.7 GHz Cortex-A53)|
|GPU <strong>GPU => </strong>A graphics processing unit (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. This include things such as lighting effects, object transformation and 3D motion.||Mali-G72 MP3|
|RAM <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.||4 GB / 6 GB RAM|
|Storage||64 GB / 128 GB|
|Expandable Storage <strong>Expandable storage or 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, via microSDXC (dedicated slot)|
|OS <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 2.5|
|User Interface <strong>UI or user interface</strong> of a device is the look and feel of the on-screen menu system. How it works, its color scheme, how it responds to button presses, all of these things are part of the user interface.||Yes|
|Rear Camera <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. Rear cameras are the cameras at the back of the phone.||Triple- 64 MP (f/1.8, wide) + 8 MP (f/2.2, ultrawide) + 5 MP (f/2.2, depth)|
