OK, for the moment I solved the notification LED problem. I installed the APP "Light Manager - LED Settings". For each tracked application (SMS, Whatsup ...) I put the notification in green LED. I still hope Bluboo finds a firmware update to resolve this problem without using APP. However, the problem of the flashing LED when the battery is charged up to 100% remains . In this case the LED must remain fixed (100% charged), no flashing.
