Hello everyone! Today I’m going to compare 2 Samsung smartphones. They are the Galaxy A31 and the Galaxy A51.
The Samsung Galaxy A31 and the Samsung Galaxy A51 are almost identical in design. They have approximately the same size and arrangement of elements on the body. But there are small differences that allow us to distinguish them from each other.
The Galaxy A31 is quite large and heavy. Some users might find it uncomfortable using it with one hand. It has a large screen with narrow frames and a fingerprint scanner built into it. The front camera of the smartphone is placed in a miniature teardrop-shaped cutout on the display. As for the location of buttons and other elements, there are the power and volume buttons on the right side of the smartphone. There is a slot designed for the simultaneous use of two Nano-format SIM cards and a memory card on the left. At the bottom of the Galaxy A31 there is a speaker, microphone, headphone input, and a USB Type-C connector.
The Samsung Galaxy A51 is only slightly different from its rival in size. But the weight is noticeably less – it is 172 grams comparing to 185 grams of the Galaxy A31. There is another difference in the appearance. The front camera of the Galaxy A51 is placed directly on the screen. The location of the connectors, buttons and other elements are totally the same. There is an on-screen fingerprint scanner. There is a triple slot designed for 2 Nano-format SIM cards and a memory card on the left side of the smartphone. There is a volume key and a power button on the right side. And the microphone, speaker, headphone input 3.5 millimeter and a USB-C connector are places below.
The differences are also little on the back side of smartphones. The Galaxy A31 and the Galaxy A51 have a plastic back cover with a prismatic pattern. Both smartphones received a rectangular camera block located in the upper left corner. But the Galaxy A31 flash in the camera unit is located higher than that one of the opponent. The Galaxy A31 can be purchased in white, black, red or blue colors.
As for the Samsung Galaxy A51, if you take a closer look at it, you will notice that the prismatic pattern on the back is made a little differently. The flash in the camera unit is located slightly lower. The Galaxy A51 is available in black, white, blue or pink.
The Samsung Galaxy A31 received the Super AMOLED screen with a diagonal of 6.4 inches and an aspect ratio of 20 to 9. The resolution is 1080 by 2400 pixels. Like all Super AMOLED screens, the Galaxy A31’s display is bright, with wide viewing angles, and deep black and rich color reproduction. In addition, the smartphone screen has excellent anti-glare properties, so the image gets perfectly visible in sunny weather.
The Samsung Galaxy A51 also received a screen with the Super AMOLED matrix, which has a resolution of 1080 by 2400 pixels and an aspect ratio of 20 to 9. The difference is only in size. The screen size of the Galaxy A51 is 6.5 inches.
Both the Samsung Galaxy A31 and the Samsung Galaxy A51 run on the Android 10 operating system with the latest version of the proprietary One UI 2 shell. The updated shell received not only design is a night mode and a dark theme integrated into most applications. The interface itself has become more intuitive. The hardware and software work so smoothly that users of smartphones on One UI 2 get access to all functions and content faster than before. In addition, the smartphones have Game Booster app that optimizes performance and increases their performance during games. There is the Samsung Knox security system to protect user’s data from viruses and malicious attacks.
The Samsung Galaxy A31 has a quad camera on the back consisting of the main 48-megapixel module, an 8-megapixel ultra-wide module, as well as the 2 depth and the macro sensors of 5 megapixels each. The main camera allows you to take bright and clear pictures with the right settings and good lighting. The ultra-wide-angle module with a viewing angle of 123 degrees will allow you to capture more objects in the frame. The depth sensor with the Live Focus function perfectly blurs the background, which allows you to make high-quality portrait shots. The macro camera allows you to take photos at close range. In general, the photo capabilities of the Galaxy A31 are quite high. But video shooting on the smartphone can only be in FullHD resolution, which is somehow strange for a smartphone from the middle price segment in 2020. The front camera of the smartphone received a 20 megapixel sensor. It has the “Self-focus” function, with which you can take beautiful and vivid selfie pictures.
The Samsung Galaxy A51 also received the main 48-megapixel module of the main camera, which allows you to take high-resolution pictures of good quality. Unlike its rival, the Galaxy A51 has an ultra-wide module with 12 megapixels with a viewing angle of 123 degrees. As for the depth sensor and macro shots, they are te same – they are 5 megapixels each. The daytime shots taken with the main camera of the Galaxy A51 are not bad, but in low light and at night the quality drops noticeably. As for video shooting, everything is much better comparing to the opponent. The Galaxy A51 can record video in 4K resolution at a frequency of 30 frames per second. As for the front camera of the smartphone, it has 32 megapixels. Therefore, in comparison with cameras, the Galaxy A51 has a noticeable advantage.
The Samsung Galaxy A31 is equipped with a fast 8-core Mediatek processor. Its 2 cores operate at a frequency of 2 GHz, and the remaining 6 operate at a frequency of 1.7 GHz. Together with 4 or 6 GB of RAM, it demonstrates good performance and ensures fast work of games and applications. The amount of ROM of the smartphone can be 64 or 128 GB, which at any time can be increased using a memory card.
The Samsung Galaxy A51 has an 8-core Exynos 9611 processor. It has 4 Cortex-A73 cores operating at a frequency of 2.3 GHz and 4 Cortex-A53 cores operating at a frequency of 1.7 GHz. As for RAM, the smartphone is available in versions of 4, 6, and 8 GB. The amount of permanent memory can be 64 or 128 GB. In addition, the smartphone can have a memory card installed with a maximum capacity of 512 GB.
As for the communication capabilities of the Samsung Galaxy A31 and the Samsung Galaxy A51, there are no differences. Both smartphones support all common types of mobile networks and the Wi-Fi standard ACC. They have installed Bluetooth version 5.0, and there is also the NFC module.
The battery capacity of the Samsung Galaxy A31 is 5000 mAh, which allows the smartphone to work for a long period of time. According to the developers, the smartphone can work for 20 hours in the watching video mode or surfing the web. The support for fast charging technology allows you to quickly restore battery power and always stay connected.
