Comparison review
The Xiaomi Mi MIX is slightly better than the Samsung Galaxy A21, getting a score of 76.2 against 76.1. Both of these devices have Android OS (Operating System), but the Xiaomi Mi MIX has a more recent 6.0 Marshmallow version while Samsung Galaxy A21 has Android 10 version, so it provides you a couple nice extra features. Although the Xiaomi Mi MIX is notably older and a little bit heavier than Samsung Galaxy A21, it's construction is still a little thinner.
Galaxy A21 counts with a bit better hardware performance than Xiaomi Mi MIX, because although it has a lower amount of RAM, it also counts with 4 more processing cores. The Xiaomi Mi MIX features a sharper display than Galaxy A21, because although it has a little bit smaller display, it also counts with a higher pixel count in each display inch and a higher resolution of 1080 x 2040 pixels.
Xiaomi Mi MIX has a little bit better memory for apps and games than Galaxy A21, because although it has no external memory card slot, it also counts with 96 GB more internal memory capacity. Xiaomi Mi MIX shoots clearer videos and photos than Samsung Galaxy A21, because although it has a smaller diafragm aperture which is worse for taking photos and/or video in poorly lited environments, and they both have a 16 megapixels camera and a same size back camera sensor, the Xiaomi Mi MIX also counts with a much higher (4K) video quality.
Xiaomi Mi MIX features just a bit better battery duration than Samsung Galaxy A21, because it has a 4400mAh battery size.
Although Xiaomi Mi MIX is a better device, it is a lot more expensive than the Galaxy A21, and it doesn't have such a good relation between it's price and quality as Galaxy A21. So if you need that extra specs and features, you can buy the Xiaomi Mi MIX, but if you don't you can save a couple dollars and get the Galaxy A21, resigning some specs and features.
