I am writing this post for all those who like Samsung displays and want to purchase Samsung devices only due to their Super Amoled displays.
Please note that A31 display is although super Amoled in written but when you compare it with other Samsung devices (A30, A30s, A20,A50) then you will be disappointed a lot. Its display is more like vivo,oppo phones. I personally used it and sold it after 2 days because it was not looking a Samsung device at all. If you are looking for good display phone in this range then A30s, A50 is good choice.
