While Android’s ability to adjust brightness is valuable in most scenarios, there are instances where disabling end users from configuring this setting becomes necessary. Whether it is to maintain consistency, improve security, optimize performance, or conserve energy, the ability to restrict brightness adjustments provides administrators with a greater degree of control over Android devices in various environments.
Moreover, in certain specialized use cases, such as kiosk systems, public displays, or dedicated hardware devices, preventing users from altering brightness settings becomes crucial. These devices are designed to serve specific purposes, and any unauthorized changes to brightness can lead to suboptimal performance, diminished visibility, or even damage to the equipment.
