I'm sorry to telling you that Samsung A31 with 6 gb ram and 128 gb storage is so much bad in wifi, while you are connected with nearest wifi and you put your hand behind the phone i mean near with camera you automatically lost your wifi connection or says it become week.
Secondly there are 4 cameras in Samsung A31 but i didn't find the 4th one while i using cameras, need your full attention on this.
