After 1 month of use the high speaker comes to sizzles and saturates at the end of a few seconds. I thus have the same problem as the other buyers who wrote on the forum.
The quality of sound degrades from day to day
Really saddening that no solution is given by the manufacturer !
If top speakers are defective, Blackview has to say it and make a gesture for the buyers-
The telephone was updated with rom version 20170418 then 20170804 then 20170814 with reset factory and nothing helped
Here is the video of the problem :
