What is the Water Lock mode on the Galaxy Watch?
The Galaxy Watch is rated 5ATM water and dust resistant, which means it can withstand being used in the pool, the rain, or a post-workout shower. Be sure to turn on Water lock mode before swimming or exercising in water.
When Water Lock mode is enabled, the touchscreen, the wake-up gesture feature, and watch always on feature will be deactivated.
When you select Exercise > Swimming menu, the Water Lock mode will be activated automatically.
To turn off Water lock mode and eject water press and hold the Home button.
Please note: After you have turned off the Water lock feature be sure to remove water from inside the speaker. Do this by playing a loud sound on the Galaxty Watch.
Open the Apps screen → tap Settings → Advanced → Water lock mode → Eject water → Play sound.
