we purchased the fridge 2 months ago and the fridge is working good, however the touch screen is freezing constantly..you can not touch or do anything on it when it freezes.. so you need to turn it off and wait for few minutes then turn on, it does work for hour or so then freezes again. 
even the support team couldnt do anything the first time i tried to contact them except telling me to restart the screen from it’s power button.. then next time i tried to contact them i get stock with the robot answering machine or the awful automated chatting system. it’s disappointing to see big company like samsung has such support system. 
i’m a loyal customer to samsung so not trying to ruin their image but i’m honestly writing review based on my experience. it’s very disappointing.
