Comparison review
The Xiaomi Black Shark 4 has a global score of 88.3, which is slightly better than Galaxy A51's 85.5 general score. These devices work with the same Android 11 OS (Operating System), so you shouldn't notice any differences regarding that. The Xiaomi Black Shark 4 is a newer cellphone than the Galaxy A51, although it's heavier and incredibly thicker.
Xiaomi Black Shark 4 has a more vivid screen than Samsung Galaxy A51, because although it has a bit less pixels per inch in the screen, and they both have an equal resolution of 1080 x 2400 pixels, the Xiaomi Black Shark 4 also counts with a little bit larger screen. Samsung Galaxy A51 features a much greater memory capacity for games and applications than Xiaomi Black Shark 4, and although they both have the same internal storage capacity, the Samsung Galaxy A51 also has a slot for an external memory card that admits a maximum of 512 GB.
The Xiaomi Black Shark 4 counts with a bit faster CPU than Samsung Galaxy A51, and although they both have 8 CPU cores, the Xiaomi Black Shark 4 also has a higher amount of RAM. The Xiaomi Black Shark 4 features a little better battery lifetime than Samsung Galaxy A51, because it has a 13 percent bigger battery size.
Xiaomi Black Shark 4 has just a bit better camera than Samsung Galaxy A51, and although they both have the same (4K) video quality, a 0.5 inches back camera sensor and a back camera with a 48 mega-pixels, the Xiaomi Black Shark 4 also has a larger camera aperture for better photography in poorly lited situations and faster 60 fps video frame rate.
Although Xiaomi Black Shark 4 is a better device, it is way more expensive than the Galaxy A51, and it doesn't have such a good relation between it's price and quality as Galaxy A51. If you are trying to save a few dollars, you can get Galaxy A51, giving up a couple features, but you will get the most out of your money.
