The ability to adjust the brightness of a mobile device’s light-emitting diode (LED) illumination is a feature implemented in some software versions for a specific mobile operating system, potentially referencing a development cycle or iteration associated with an alphanumeric identifier. This functionality allows users to modulate the luminous output of the flash, providing greater control over its application in various scenarios. For example, a lower setting might be preferred for reading in dark environments to minimize eye strain, while a higher setting would be useful for illuminating a larger area or signaling in emergencies.
The implementation of adjustable luminous emittance on handheld devices enhances user experience by offering versatility and conserving power. Historically, mobile device flashlights were limited to a single, fixed intensity. The advent of granular control offers significant advantages, including extended battery life when operating at lower output levels, improved photographic capabilities by avoiding overexposure, and increased user comfort in low-light situations. This feature has become increasingly expected by consumers as device capabilities expand.
