Hey Admin,
I just figured out a bug on my Bv6000s which I also noticed on my Bv6000 before.
When Bluetooth is turned on, the Wifi-Speed is decreasing a lot.
In my case I dont get more than 200 Kb/s Download when the Bluetooth is turned on. When I turn it off, Ill get more than 50mb/s.

As I said, I had the same Issue on the Bv6000 as well.
Im not sure if its a hardware problem or if there is just something wrong in the Rom.

Maybe you can handle over this report to the developer team. Could be easy to fix maybe.

Thanks a lot for your attention.

Best regards from Germany
Moritz
