Price comparison

Design

1.weather-sealed (splashproof)
Allview V4 Viper Pro
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
2.weight

191.6g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
3.thickness

8.8mm

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

171mm

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

82mm

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

123.39cm³

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

220ppi

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

640 x 1352px

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

6.8"

The bigger the screen size is, the better the user experience.
4.has branded damage-resistant glass
Allview V4 Viper Pro
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
Allview V4 Viper Pro
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
Allview V4 Viper Pro
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

4 x 1.5GHz (MediaTek MT6739)

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

2GB

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
Allview V4 Viper Pro
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

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
Allview V4 Viper Pro (MediaTek MT6739)
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 & 0.3MP

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

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
Allview V4 Viper Pro
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

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.Has a dual-tone LED flash
Allview V4 Viper Pro
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.
6.has a BSI sensor
Allview V4 Viper Pro
A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.

Audio

1.has stereo speakers
Allview V4 Viper Pro
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
Allview V4 Viper Pro
With a standard mini jack socket, you can use the device with most headphones.
3.Has a radio
Allview V4 Viper Pro
A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.
4.number of microphones

2

More microphones result in better sound quality and enable the device to filter out background noise.

Battery

1.battery power

3500mAh

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.

5.Has an ultra power-saving mode
Allview V4 Viper Pro (Android 9.0 Pie)
The ultra power-saving mode, also called low power mode, is an effective way to extend the battery life of the device. Usually, it involves limiting screen brightness and contrast, disabling location services, restricting connectivity, and turning off nonessential apps.
6.has a battery level indicator
Allview V4 Viper Pro
An indicator shows you when the device has low battery.
