After a 5-minute search around Google Play for a simple flashlight app led me nowhere, I decided to make my own, Light Light. The app simply toggles your Android device's camera flash LED so that you can use your phone as a flashlight. Also, it has a setting for turning the flash on by default when the app starts. I didn't find many apps that do this, and I thought it would be a nice feature to have, because if you are starting a flashlight app, chances are you want the light to turn on ASAP.
The app does require two permissions - CAMERA and INTERNET. CAMERA is used for access to the camera flash, while INTERNET is used for displaying ads. If the ads bother you, there's a simple setting to turn them off - feel free to do so. The app does not collect any data whatsoever or use the INTERNET permission for anything else. There are never any notifications. Please give it a try and let me know what you think.
