Most people use their phone flashlight as a simple on-and-off tool, but recent software updates for iPhone and Samsung devices have introduced more advanced features. These updates allow users to adjust brightness and, on some models, control the beam width, enhancing functionality without requiring hardware upgrades.
Core Features Across Devices
On nearly all iPhones, users can adjust flashlight brightness by swiping down to open Control Center, pressing and holding the flashlight icon, and dragging the vertical slider. This feature has been available for years but remains underutilized. Samsung devices offer similar brightness controls, though the exact steps may vary slightly.
Pro-Exclusive Beam Width Adjustment
Newer iPhone Pro models running iOS 18 and later, including the iPhone 14 Pro and iPhone 15 Pro, support beam width adjustment. Users can swipe left or right after pressing and holding the flashlight icon to switch between a narrow, focused beam (ideal for distance) and a wide floodlight (better for illuminating larger areas). This feature is exclusive to Pro models and is not available on standard iPhones.
Accessibility and Convenience
Both iPhone and Samsung allow users to access and adjust flashlight settings without unlocking the device. This feature is particularly useful in emergencies or low-light situations where quick access is critical.
Software Compatibility
The beam width adjustment feature was introduced in iOS 18 and remains available in iOS 26.4. Samsung’s equivalent functionality varies by model and software version, with some devices offering brightness control and others providing additional customization options.
User Experience
Many users remain unaware of these advanced flashlight features, as they are often buried in settings or require specific gestures. Manufacturers have not heavily promoted these updates, leaving them as hidden gems for tech-savvy individuals to discover.
