Ours arrived today while we were visiting DC with out of town relatives. We did a signature release that Fed Ex actually accepted. Of course it meant our packages sat out on the front porch in some rain all day, but nothing really got wet, so all is well. I have not really had much chance to do more than put it in the case to admire it with the relatives, who are the only Samsung enthusiasts in the family. They liked it but would prefer flat, not edges.
I am very happy with the S8 + form factor. I'm disappointed to read that the scanner sounds a lot like the crappy unusable one on my S7 and S7 Edge. I'll probably stick with using a pin. Or try a pattern.
I am going to wash the grit and humidity of D.C. off and then play with my new phone a little bit. I'm too tired after walking six miles in heat and humidity to do much with it. Ttyl.
