Comparison review

Both phones in this review include Android OS, but the Sony Xperia Z4v has an older 5.1 version and Samsung Galaxy A21 has Android 10. Sony Xperia Z4v is an extremely older and just a little bit thicker phone than Samsung Galaxy A21, but Sony managed to make it lighter anyway.
Xperia Z4v has a much better looking screen than Samsung Galaxy A21, because although it has a lot smaller display, it also counts with a lot higher 2560 x 1440 pixels resolution and a way better screen pixels density. The Samsung Galaxy A21 has a way bigger storage capacity for games and applications than Xperia Z4v, and although they both have exactly the same 32 GB internal storage, the Samsung Galaxy A21 also has a slot for external memory cards that allows a maximum of 512 GB.
The Xperia Z4v features a bit superior processing unit than Galaxy A21, and although they both have the same number of cores and the same RAM memory amount, the Xperia Z4v also has an additional graphics processing unit. The Sony Xperia Z4v takes better photographs and videos than Galaxy A21, because although it has a smaller diafragm aperture which is worse for low-light photography and videos, it also counts with a much better video definition, a lot better 20.7 MP resolution back-facing camera and a much larger back-facing camera sensor taking more light and vivid colors.
Samsung Galaxy A21 has superior battery lifetime than Xperia Z4v, because it has 4000mAh of battery capacity.
Although Sony Xperia Z4v is a better device, it costs more than the Samsung Galaxy A21, and it doesn't have such a good price and quality relation as the Samsung Galaxy A21. So if you want that extra specs and features, you can buy the Sony Xperia Z4v, but if you don't you can save some dollars and get the Samsung Galaxy A21, letting go a couple specs and features.
