The Samsung Galaxy Watch Ultra Quick Button is one of its most useful perks if you're an athlete. By default, it pulls up your Samsung Health exercises with a single click, lets you quickly pause or restart a workout without needing the touchscreen, and even triggers an ear-ringing siren in an emergency.
At the same time, you may want to change your Galaxy Watch Ultra's Quick Button shortcut to something else, like a flashlight. You can also change which exercise it pulls up, disable the siren entirely, or make other simple changes.
