With the N900, one of the things that I have missed is using the dual LED as a flashlight in the dark and as a source of illumination while recording video. Fortunately, a simple app called ‘Flashlight’ can change all that. Once installed, it adds a toggle switch to the N900’s status bar which you can tap to enable or disable the flashlight.
The Flashlight switch will only show if the camera cover has been slid open. To use it in the video mode, start the flashlight and start video capture, the LED’s will automatically get disabled. Now hit the toggle switch to enable the light again.
Flashlight is available from the extras-devel repository which means it is in the development stage right now and is not recommended for normal consumers, but if you are up for beta-testing it, follow these directions to enable extras-devel if you already haven’t.
