How to Adjust the Flashlight Beam in iOS 18

Apple introduced a major overhaul to the flashlight controls in iOS 18, transforming the standard toggle into a precise, multi-axis lighting tool. On supported hardware, the update utilizes the Dynamic Island and an advanced flash array to let users fine-tune both the brightness intensity and the beam width. This article explains the hardware requirements, the interactive interface, and how to navigate the new controls.

Supported Hardware Requirements

The advanced beam adjustment features are not available on all iPhones running iOS 18. The capability relies on Apple’s Adaptive True Tone flash, which features an array of individually controlled LEDs. This hardware is present on the following models:

  • iPhone 14 Pro and iPhone 14 Pro Max
  • iPhone 15 Pro and iPhone 15 Pro Max
  • All iPhone 16 models (iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max)

Devices lacking this specific flash hardware—such as standard iPhone 14 and iPhone 15 models—retain standard brightness adjustments without beam-width control.

The Dynamic Island Interface

When you activate the flashlight via the Lock Screen, Control Center, Action Button, or Siri, the Dynamic Island immediately expands into an interactive, dedicated control surface.

The interface features an illuminated graphic representing an overhead view of a flashlight beam. Below the beam graphic is a virtual trackpad area, accompanied by a power toggle icon. The interface remains active as long as the light is on, providing real-time visual feedback that mirrors the physical output of the LEDs.

Operating the Multi-Axis Touch Controls

The user interface uses a dual-axis touchpad mechanic that allows simultaneous or independent adjustments:

  • Vertical Axis (Brightness): Sliding your finger upward increases the light intensity, while sliding downward dims it. The visual indicator brightens or darkens in real time.
  • Horizontal Axis (Beam Width): Sliding your finger to the right widens the beam into a broad floodlight, activating the outer LEDs in the array. Sliding your finger to the left narrows the beam into a focused spotlight, concentrating the light in the center.
  • Diagonal and Fluid Dragging: You do not need to adjust the axes separately. You can drag your finger diagonally across the Dynamic Island to change both beam spread and brightness simultaneously in a single, fluid motion.

Haptics and Dismissal

As you adjust the beam, the Taptic Engine provides responsive haptic feedback, delivering subtle clicks that correspond to maximum, minimum, and threshold points along both axes.

Once configured, the interface collapses back into a compact Dynamic Island pill showing a small flashlight icon. Tapping the Dynamic Island expands the controls again. To turn the light off, you can tap the power icon within the expanded interface, press the flashlight icon in the Lock Screen or Control Center, or tap the collapsed Dynamic Island indicator directly. The system remembers your last-used beam settings for the next time the flashlight is activated.
