This is just a marketing strategy in smartphone industries. We get ram in mobile phone as a part and same goes to storage. Now you tell me, how a storage( virtual ram add in internal storage) could improve the device multitask. It's like " lots of people know that, more ram means more performance, as we know overall matter like processor, storage type, UI etc."
I did not face any issue but in sameway didn't notice any huge improvements, just feels smoother experience. In next updates samsung will fix if anyone facing any problem.
