You must get A12 now because A20 is 3G, not 5G.

I bought my Samsung Galaxy A20 in December 2019, I m very happy with it, the phone still works fine, and the battery size is 4000. mah, it lasts me a long time, the only thing I like about the A12 is because it comes with 5000mah, battery, other than that I DON'T think is much difference.
