I know that Blackview is not focussed on devices already sold, that's why I waited some weeks after the publication of the blueborn vulnerability to ask: will there be a fix for this security issue?
Will it be within this year or this decade?
Oh, and will it be available also for devices already shipped?
Will it be user friendly OTA or developer friendly flash tool update?

I lknow, a lot of questions, but may be there will be some answers before end of next month...
