I know under settings/display you can turn off the notification pulse.
I've done that because it lights up the room at night and I don't really need it that much.
However the setting keeps reverting back to on...
I think I may have figured out why today but don't know how to stop it.
I use Handcent for my messaging.
Today I noticed that the light was being toggled back on when I get an SMS...
Any idea how to stop this?
