Comparison review
The Samsung Galaxy A31 has a general score of 81.3, which is a little bit better than the Galaxy M20's 78.9 general score. These phones have the same Android 10 OS (Operating System), so both of them should provide the user identical OS features. The Samsung Galaxy A31 design is newer, just a little lighter and just a little bit thinner than Galaxy M20.
Galaxy A31 has a little bit better display than Samsung Galaxy M20, because it has a quite larger screen, a little more pixels per inch in the screen and a quite better 1080 x 2400 resolution. Galaxy A31 has a bit more powerful processing unit than Galaxy M20. They have the same number of cores and 4 GB of RAM.
The Galaxy A31 captures much clearer videos and photos than Galaxy M20, because although it has a tinier diafragm aperture which is not good for shooting pictures and/or video in low light environments, and they both have the same (Full HD) video definition and the same 30 frames per second video frame rates, the Galaxy A31 also counts with a way higher resolution back facing camera and a much bigger back camera sensor capturing way better quality photographs.
Galaxy A31's memory for applications, games, photos and videos is very similar to the Galaxy M20 one, both have equal 64 GB internal memory and a SD memory slot that holds up to 512 GB. Galaxy A31 has a battery life that's just as good as the battery lifetime in Galaxy M20.
