Price comparison

Design

1.weight

156g

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.
2.thickness

9.6mm

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.
3.height

150.3mm

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

74.3mm

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

107.21cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.
6.has a physical QWERTY keyboard
Blu R2
Text messaging is much faster due to a hardware keyboard.

Display

1.pixel density

282ppi

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 1280px

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

5.2"

The bigger the screen size is, the better the user experience.
4.LCD display with 3 subpixels per pixels
Blu R2
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.
5.has an IPS screen
Blu R2
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.
6.has a touch screen
Blu R2
You can operate the device easily, by pressing the screen with your fingers.

Performance

1.CPU speed

4 x 1.3GHz (MediaTek MT6580)

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

1GB

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
Blu R2
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

8GB

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.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.
6.GPU clock speed
The graphics processing unit (GPU) has a higher clock speed.

Cameras

1.megapixels (main camera)

8MP

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.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.
4.wide aperture (main camera)

f/2.0

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.
5.Has a dual-tone LED flash
Blu R2
A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.
6.has a flash
Blu R2
A flash is good for low-light environments, and can sometimes be used as flashlight.

Audio

1.has stereo speakers
Blu R2
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
Blu R2
With a standard mini jack socket, you can use the device with most headphones.
3.Has a radio
Blu R2
A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.

Battery

1.battery power

3000mAh

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.
2.has a removable battery
Blu R2
The battery is removable and can be replaced by the user if broken.
3.has wireless charging
Blu R2
The manufacturer offers a branded wireless charging kit. To charge the device, you simply put it down on its charging base.
4.Has an ultra power-saving mode
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.
5.Battery life

26h

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.
6.has a battery level indicator
Blu R2
An indicator shows you when the device has low battery.

Features

1.Has a fingerprint scanner
Blu R2
The device has a fingerprint scanner which identifies the user.
2.Bluetooth version

4

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
3.supports two SIM cards
Blu R2
A dual-SIM mobile phone can work with two SIM cards at the same time.
4.is a multi-user system
A multi-user operating system allows multiple users to access the device. Each user has a dedicated profile with apps and data available only to them.
5.The browser has word wrap
