[android-developers] Re: Cannot get LED notifications to work on my Motorola Droid (with Froyo)

Never mind: I figured out the issue. Apparently after the 2.1
update, the notification light on the Motorola Droid only blinks when
the screen is blank (http://androidforums.com/motorola-droid/76585-
help-led-notification-light-stopped-working.html). I never really
noticed the change, but I was able to confirm the fact. Once the
screen is lit, the notification light goes off.
