Hello,
Today I had a couple i777's taken apart that I was fiddling with while I replaced the screen on one, and noticed that there is a location (facing the screen, the top right hand corner) that is just a metal brick. Possibly a heat sink, that could easily be drilled out to install a LED light for notifications! Then I was thinking about the location for soldering the light on, and thought.. Why not solder in line with the camera LED? There are apps that use the camera LED for flash notifications, right?
The only thing is, the camera LED would flash when the notification LED flashed.. Also there could only be 1 color LED, and visa versa, so if you took a picture with flash, notification LED would blink. Not too big of a problem though right? There would not need to be any drilling of the screen either.

You would need a current limiting resistor for the new notification led. If you make the same current available to that led as the high power flash led, you will release the magic smoke.

Right of course! All LEDs need resisters, but some come in Little light sister packages
