Bright Flashlight is an app that allows you to use the phone's screen and camera LED as a flashlight. The phone's screen will stay on until the app is exited. I designed it to not use too much of the battery by having no ads and not using a wakelock.
Light Sources:
1. Camera LED (If your phone has one)
2. Screen
Features:
1. Ad-Free
2. No shady permissions
3. Large "Torch" button for easy use
4. Small file size
5. Fast switch on/off
