"There are many customers asking about the phones but the actual number of preorders seems to be a tad smaller compared to last year," said an employee of a local mobile operator, declining to be named.

South Korean customers can preorder the smartphone on the mobile operators' websites or by visiting the retail outlets of local mobile carriers.

Samsung's new devices boast improved camera function and were unveiled on the eve of the Mobile World Congress in Barcelona, Spain, earlier in the week.

At the MWC, LG also showcased its V3OS ThinQ, which retains the exact same design as the V30 but with added artificial intelligence features.

"Not many consumers are well aware of the new products, as it has only been two days since the companies unveiled the latest models at the MWC," another observer said.

The Galaxy S9 costs 957,000 won ($884) for the base 64 GB version in the South Korean market, while a Galaxy S9 Plus with the same memory capacity is 1.05 million won, Samsung said.

The price tag of the 125 GB V30S is 1.04 million won and that of the V30S Plus with 256 GB of onboard storage is 1.09 million won, LG said. (Yonhap)
