I have exactly the same problems and my phone runs last version 20170708.

Thanks everyone.....
However it would be great if blackview will continue to keep update our bv6000.
Thanks

I am happy to tell that with a factory reset I finally sorted out my problems and I would like to thank blackview for the last update that works very well so far.

This is my third message and I hope it will be finally published. My WiFi keep switching off all the times when I am listening to music with my Bluetooth speaker jbl flip3. My internet provider is BT. I am in London. Can you please do anything about? It is really annoying.... Hope not to write this ...

Since I have bought my bv6000 a year ago I always had a problem with my speaker Bluetooth jbl flip 3. When I listen to music on the web ( BT provider ) through my speaker my internet connection suddenly switch off. Can you please do anything about?
