I am on android 7 (0708) but the problem is more "large" ...
Blackview team make a big fault at the beginning because they put different components in BV6000 (screens, speakers, etc ...)
Result is that now, when bugs are related by users, fix updates are good for someone and bad for others because problems are not only software but software/material mixed ...
I think that there will be no solution for all users but each one now have to test the better ROM configuration for him (with necessary flash and reflash ROMs)
I hope BV6000 will be a good lesson for BV team ... not sure.
