Display Colors Display Colors is refers to the number of different shades of colors that the screen is capable of displaying => 64K colors, 256K colors and 16 million colors, Obviously 16M is highest available range of colors and better than others. | 16M colors |
Pixel Density Pixel Density (PPI) is refers to the concentration of pixels on a particular display, measured in pixels per inch (ppi). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size, higher pixel density better display quality. | ~270 ppi density |
Touch Screen | ~79.3% screen-to-body ratio |
Operating System OS => 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 |
CPU CPU (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 & 4x1.8 GHz) |
Card Slot Memory Card Slot 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. | microSDXC (dedicated slot) |
