If you keep opening the same apps or digging through settings on your Samsung Galaxy phone, there’s a faster way. Your Galaxy has more buttons than you think — and most of them can be reprogrammed. Here’s how to unlock them using built-in settings and Samsung’s Good Lock apps.

1. Remap the Side Button’s Double Press on Your Samsung Galaxy
Double-pressing the side button can do far more than open the camera. Head to Settings -> Advanced features -> Side button -> Double press and enable it. You can pick from the torch, Magnifier, Voice Recorder, Samsung Notes, Samsung Capture and more — or set it to launch any app you choose. A gear icon beside an option unlocks extra settings, like a specific camera mode or recording action.
On the same page you can also configure the long press separately, choosing between the digital assistant, Bixby or the power-off menu.
2. Add a Floating Shutter Button to the Samsung Camera App
One-handed photography is awkward when your thumb can’t reach the shutter. Open the Camera app, tap Quick Control (the four-dot icon), then the Settings gear. Go to Shooting methods and turn on the Floating Shutter button. Back in Photo mode, drag the extra button to wherever your thumb rests — perfect for selfies, awkward angles and cramped group shots.
3. Tap the Back of Your Galaxy Phone With Good Lock’s RegiStar
Samsung’s RegiStar module lets you trigger shortcuts by tapping the back of your phone — double-tap to open an app, triple-tap to take a screenshot, with a different action per gesture. Install Good Lock from the Galaxy Store, open it, download RegiStar, then open RegiStar and turn on the Back-Tap action. Pick “Double Tap,” choose “Open app,” and select your app. With the phone unlocked, tap the back twice to test it.
Good Lock is built around modules, so you only install the add-ons you want — lock screen tweaks, navigation-bar changes and button shortcuts among them.
