Turn Camera Flash On or Off auf Samsung
The Samsung Camera app has three flash states: Auto, On, and Off. In Auto mode, the camera measures the ambient light and decides on its own whether to fire the flash for a photo. That logic works well in mixed lighting but often misfires in dim rooms, backlit scenes, or while recording video, where the flash behaves differently than in photo mode.
To take manual control, use the flash icon in the viewfinder: Tap on Camera ➔ Tap on Flash ➔ Enable or disable Flash. Tapping the icon cycles through the three states without leaving the camera screen.
Forcing the flash on guarantees extra light for close-up shots, documents, or barcodes, but it can wash out skin tones and create harsh shadows. Forcing it off keeps colors natural in low light at the cost of more noise or a slower shutter, which can cause blur. Leave the setting on Auto for everyday photography and only switch to a fixed state when you already know the lighting conditions.
On many mid-range and high-end Samsung phones, low-light software processing already compensates for weak lighting, so the flash is used less often than on older or budget models.
