Sit tight, Members! We’re talking about the first-ever underwater expedition captured on a smartphone with Nat Geo Traveller India. Take a deep dive into the oceans #withGalaxy S21 Ultra.
Uncover the Epic with Malaika Vaz as she explores the depths of the Shark Island of Maldives! Yes, it’s true.

However this is a Sea, which means Salt water. Which actually degrades the metal and cause corrosion... so its actually the build of S21 Ultra (dont know about other s21 models as of now) which made it this resilient. And it the Samsung which uses a material of their own called as Glastic (a Fuse of Glass and Plastic).
Maybe this will help.
