I am very disappointed in the S20 ultra!! The camera is not near as good as advertised. Anything over 30x zoom is worthless. Not sure this can be fixed by a software update. This may be the last Samsung phone I buy.
I have the Galaxy s20 Ultra and I'm with Sprint. I received the software update this morning and it is 423.17 MB that has a fix for the camera and other issues. So far, so good!
