I actually don’t really have any personal real-life scenario in mind, other than this being a handy little night light, where you might need a flashlight that will turn on and off automatically by itself. But then again, I feel the same way for many of the other ‘software gimmicks’ that some phones have nowadays, such as eyeball tracking software and the like. Nevertheless, the Ambient LED Flashlight is a pretty cool app that will turn on ‘only when you need it.’
Developed by XDA Forum Member apple4life, Ambient LED Flashlight uses your device’s light sensor to know exactly when you need or don’t need light. With the flexibility to calibrate with a lux meter exactly in what light conditions you need the flashlight to be on and off, the app will then activate and deactivate the LED flash of your device accordingly. Hence, the scenario of transforming your phone into a night light.
Apple4life has also integrated a feature, whereby you can activate the LED flash with a simple shake of the device. Of course, both the light sensor and the shake features work on top of Ambient LED Flashlight’s basic function of being a typical flashlight. If you would like to turn off the light sensor and shake features, you can do so through the settings menu. Apple4life also acknowledges that some devices may react slower if using the light sensor, an issue that is said to be attributed to the inability to get an accurate reading of the sensor.
Ambient LED Flashlight is compatible with Android versions 2.2 and newer, and kudos to apple4life for making the app free and ad-free. If you would like to check it out, head over to the original thread for more information._________
