I know it saves the battery etc but i'd like the option of having the screen as bright as i want it and not how it thinks i should have it :smileyhappy: Thanks. The AmbientLightSensor interface of the the Sensor APIs returns the current light level or illuminance of the ambient light around the hosting device. share | improve this answer | follow | answered Sep 1 '11 at 21:03. They can detect how much light is in a room and raise or lower the brightness to a more comfortable level for the user. Each device has a specific operating range of performance, from very low light up to bright sunlight. Ambient light sensor in mobile phones automatically adjust the brightness of the screen back-light both to improve battery life and makes it easier to see the screen. So this avoids the screen brightness whenever the users are modified for vision within a dark room otherwise less brightness as the mobile is utilized outdoors during the daytime. Many modern electronics, such as computers, wireless phones, and televisions, use ambient light sensors to automatically control the brightness of a screen, especially in low-light or high-light situations. 1.
