Turn Show Palm On or Off for Selfies auf Samsung
The Show palm gesture uses the front camera's face and hand detection to start a countdown timer whenever it sees an open palm facing the lens. Samsung enables this feature by default on most devices running One UI, because it lets you trigger a selfie without touching the screen.
The camera fires the shutter about three seconds after detecting your palm, giving you time to lower your hand and pose. In practice, the same gesture can activate accidentally during video calls, group photos, or whenever you wave near the front lens, producing extra shots you did not intend to take.
Where to find the setting
Open Camera, tap Settings, then go to Shooting methods. From there you can enable or disable Show palm without affecting any other shooting method, such as voice control or a floating shutter button.
Turning the gesture off stops the countdown from starting when the camera detects a hand, but it does not change how the shutter button, timer, or other selfie shortcuts behave. If you rely on the front camera for hands-free portraits, keep the option active and move your hand out of frame right after showing your palm, so the countdown does not restart.
