3.thickness

7.8mm

8.3mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
4.height

158.4mm

155.1mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
5.width

74.7mm

75.1mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
6.volume

92.29cm³

96.68cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

Display

1.pixel density

268ppi

270ppi

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
2.resolution

720 x 1560px

750 x 1520px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
3.screen size

6.4"

6.22"

The bigger the screen size is, the better the user experience.
4.has branded damage-resistant glass
Samsung Galaxy A20
Vivo Y91
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.
5.LCD display with 3 subpixels per pixels
Samsung Galaxy A20
Vivo Y91
The device has an LCD display with 3 subpixels per pixel, resulting in sharp and crisp images. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
6.has an IPS screen
Samsung Galaxy A20
Vivo Y91
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.

Performance

1.CPU speed

2 x 1.6GHz & 6 x 1.35GHz (Samsung Exynos 7884)

4 x 1.95GHz & 4 x 1.45GHz (Qualcomm Snapdragon 439)

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
2.RAM

3GB

3GB

Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
3.has an external memory slot
Samsung Galaxy A20
Vivo Y91
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
4.internal storage

32GB

64GB

The internal storage, also called read-only memory (ROM), refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
5.Has integrated LTE
Samsung Galaxy A20 (Samsung Exynos 7884)
The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
6.semiconductor size
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Cameras

1.megapixels (main camera)

13MP & 5MP

13MP & 2MP

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
2.megapixels (front camera)

8MP

8MP

The number of megapixels determines the resolution of the images captured with the front camera. A higher megapixel count means that the front camera is capable of capturing more details, an essential factor for taking high-resolution selfies.
3.has built-in optical image stabilization
Samsung Galaxy A20
Vivo Y91
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
4.video recording (main camera)

1080 x 30fps

1080 x 30fps

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
5.wide aperture (main camera)

f/2.2 & f/1.9

f/2.4 & f/2.2

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
6.Has a dual-tone LED flash
Samsung Galaxy A20
Vivo Y91
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.

Audio

1.has stereo speakers
Samsung Galaxy A20
Vivo Y91
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has a socket for a 3.5 mm audio jack
