Samsung Galaxy S20's construction has the same thickness than Galaxy S21, but it is just a little bit lighter. Both of these devices include Android OS (Operating System), but the Samsung Galaxy S20 has newer 13 version and Galaxy S21 has Android 11, so it offers some extra features and enhanced performance.
Samsung Galaxy S20 counts with a bit better hardware performance than Samsung Galaxy S21, and although they both have 8 CPU cores, the Samsung Galaxy S20 also has a greater amount of RAM. Galaxy S21 counts with a little bit better screen than Galaxy S20, although it has a lot less pixels per screen inch and a much lower 1080 x 2400 pixels resolution, they both have a screen with the same size.
Samsung Galaxy S20 features a way bigger memory capacity to install games and applications than Samsung Galaxy S21, and although they both have equal 128 GB internal storage capacity, the Samsung Galaxy S20 also has a slot for an external memory card that supports up to 1000 GB. The Samsung Galaxy S21 and the Samsung Galaxy S20 both have extremely similar batteries duration.

Although Samsung Galaxy S20 is a better device, it costs more money than Galaxy S21, and it doesn't have such a good quality/price relation as the Galaxy S21. If you prefer to save some money, you can buy Galaxy S21, letting go a couple features, but you'll get the most out of your budget.
