hi i had a problem where my Samsung ear bud case light would stay continuously on and would not charge the buds them selves unless this was connected to a power source.
I seemed to have fixed it now back to normal.
All I did was to set my phone on wireless power share mode - ie charging the ear bud case at the back of my phone not the wall. It made a few noises, light went to orange. When I took it off it, seemed to have reset the buds case and now is working just fine, the green light goes off and it charges the ear buds in the case now.
