The first time a phone is not completely waterproof, it will not be usable for long, a Samsung spokeswoman said.
In a phone like the Samsung Galaxy S8, which comes with a waterproofing feature, the phone is able to be used for up to a year without water damage.
It also will have no problem in water, the spokeswoman said, adding that the phone can withstand up to 1.5 meters of water.
The Samsung Galaxy Note 7 was released in November, after which Samsung launched the Note 8 smartphone, which came with a new waterproofing technology that it said will last up to two years.
The waterproofing on the new Samsung Galaxy 10.1, which is being launched later this month, was also confirmed by Samsung.
