Clear "ice" usually only originates from pools of water. The only places any amounts of water can come from in the freezer compartment of a refrigerator is from an icemaker or defrost water from the frost on the evaporator (cooling) coil melting during a defrost cycle. In the latter case, if the defrost water drain was plugged, the water could pool and eventually freeze.
I'm afraid I am not familiar with Samsung fridge models to be able to tell you where/how to go about checking that. The drainage system should start directly beneath the evaporator coil. I don't know if it will help any, but you can see exploded view parts diagrams of your model at the following link:
