The free app I added to my android phone is called "color flashlight". Yes, it shines a perfect red light from the screen for reading star charts! The same app can also make the flash LED work as a flashlight as well as do all kinds of cool things, for example, a flashing red light while walking in the dark or a flashing red and blue highway patrol light to scare other drivers on the road! I've only had my smartphone for 3 weeks and I'm totally hooked.

Hi Wayne, so, the red light comes from the screen itself, and not the flash LED's? On the Sensation, there are two LEDs that are used for the white-light flashlight and they do double duty as the camera flash. The flashlight can be set to three different brightness levels, as well as regular flashing, or flashing S.O.S. in Morse. For the LED's to shine red, they would have to be bi-color diodes. Programming won't do it alone.
