Use NMTorch to convert your phone equipped with Camera LED into a flashlight at the dark places, or use it to send messages using Camera flash LED in Morse code.
You can type up to 26 characters (A-Z and 0-9) that will be translated into Morse code on the screen, and then you can send this Morse code using your Camera flash LED.
If you are stuck in situations with no phone reception at the dark of the night, this could be your only way to communicate with someone who knows how to read the Morse code and is in a distance no farther than what your Camera flash light can reach. You can loop the message and it will run until your phone’s battery runs out.
This app is developed for Android 2.1 and is fully tested on Motorola Atrix with android 2.3.4.
You may also use the button in the main menu to turn the screen saver off, and use the main screen's white and shining background in the dark as a good source of light
