Customize your hardware buttons

You can change what the buttons on your Wear OS watch do, but the actions you assign to them and how you set those actions vary depending on your watch model.
On Galaxy Watch 4 or 5, open your watch's Settings, scroll down, select Advanced features, and then tap Customize keys. A single press navigates home, but you can assign different functions to a double press and a long press. Double presses open apps. Long presses either open your voice assistant or the power menu.
The bottom key has two functions. You can set a single press to either navigate back in the watch's UI or open a list of your recent apps.
On other Wear OS 3 watches, it's super simple. Open your watch's Settings, then tap Buttons. Note that you can't customize what either of the Google Pixel Watch's buttons do.
On pre-Wear OS 3 devices, go to Settings, tap Personalization, and select Customize hardware keys. Tap a button, then choose which app you'd like it to open.
