I have BV9600E and it has a little bug.
I explain it:
The phone has notification LED (I know it has 3 colors - GREEN when charge is OK, RED when it is charging, and BLUE when has notifications). So, you cannot change it for example: Whatsapp usually uses green color on notifications (you can change it on whatsapp config but doesnt work because android dont let it to change). Also, there are some app to config LED colours (like LED BLINKER, LIGHT FLOW ... and many others) wich can administrate LED colours but doesnt run, because ever its BLUE colour.
The error is simple: on BV9600E cannot change BLUE colour for example to personalice on application.
Must be correct this error in a firmware update ???
