I just bought a Samsung galaxy A 20 and I was surprised that I can't change the wallpaper in my message screen. It's awful that I have to look at a white screen when I send or read my nessages. I don't understand why this feature was taken away. Can someone please explain this to me? When the convid-19 is over and I get back to work. I will buy another phone and It won't be a Samsung. I'm very unhappy with this phone..
