An image of the Settings app open on a Galaxy S8 Plus has appeared online and in the “Advanced Functions” menu there's an option which reads “Quick Launch para Cámara.” The entire text is in Spanish but if you run a quick translation in Google Translate this is what you get: “Open the camera by pressing the power key twice in a quick succession.”
So if the information obtained from this leaked image is to be believed, if you want to quick launch the camera on the Galaxy S8 or the Galaxy S8 Plus, you have the option to configure the power button to do so when it's pressed twice in quick succession.
Samsung is due to unveil its new flagship smartphone next week on March 29.
