I am using Samsung Galaxy M31 and I have problems as given below: 1) Today I received software update noice and when I try it to download it doesn’t show any signs or button to download and started to hang ?????????? 2) I have noticed that there are no more features more than a simple mobile phone but after buying it so. Bad I was worried and anger on that person who sells to me . I want to say that don’t buy this phone of you want to buy any Mobile
