I had this refrigerator delivered on Christmas eve, in time for the family Holiday Dinner. 
After only six weeks the ice maker has gone bad. 
The Dealer had to order a complete new unit and we have been without ice for two weeks and counting. 
The WiFi did not recognize my phone and I had to do an update on the app three times to get it to work, but it really is kinda useless unless you need to know if the door was left open. 
Still though, I am a Big fan of SAMSUNG ,and I'm sure when I get the ice maker replaced it will be good for many years to come. 
We will be purchasing a new Top of the Line SAMSUNG Dishwasher soon.
