A free program for Android, by Timothy Johns.
The Hydroponics Green Screen Light app allows you to use your phone as a high-powered flashlight with no extra hardware or modifications. It works in both indoor and outdoor environments and allows you to use it as a white, blue, red, or green light. There is no need for any other LED light or special bulbs. The only thing you need to do is download it and install it on your Android device.
How can it be used?
First, you need to open the app and tap on the "Settings" option. You will be able to change the light color and adjust the brightness. To turn the light on or off, tap on the "Green Screen" option.
It is recommended to use the app with your Android phone.
