WiFi and Bluetooth not working together

[AC Question]

Whenever I switch Bluetooth on, I get intermittent WiFi connection or no WiFi at all.
As soon as I tien Bluetooth off the WiFi works again.
I had the same problem on my Motorola x and now exactly the same on my new Samsung A5 so it seems like a software issue?
I tried at 2 different locations with different routers and same problem so don't think it's a channel issue.

Are you pairing the Bluetooth with something when this happens, or it's just enabling Bluetooth that does it? Do you usually have BT turned off?
