Well, compared to the S9 +, it lacks: a touch-sensitive home button, a pulse and oxygen sensor in the blood, an iris sensor. Also Protected Folder (the reason why I don't leave Samsung) is cut off (with the same version as on S9+). For some reason, there is no archiving in it and it looks like the first version of the product. It's just mind-boggling. After upgrading to 4 generations, I received a clearer fingerprint sensor from the pluses. Didn't see any other benefits. There are many more cons.
