Samsung m31 is a really good product according to its price, the s-amoled and the battery backup is really appreciable. 6000mah battery is a monster and its 64 megapixel camera is really good.
These were the positive points of the phone.
The m series has the same processor ( except m51) the m20, 21, 30, 31s all have the same processor that is a bit disappointing.
The marco camera is not as good as expected.
I’ve been using for a month or 2 and its good for normal use and multi tasking, it can be used for mid gaming but it bottleneck.
In total its a good product for me
