Just use the aod display. It's not that necessary to have the LED notification when charging it's very visible to see what's the status and just tap your screen and it will display messages and other stuff..
What really gets me with this, is that we are told a work around is in the pipeline. It isnt. The phone isnt far off a year old, and i hear on the grapevine it was never on the cards. Dunno why samsung feels the need to lie to its customers. Again.
