Bluetooth conversation sound does not appear if pgine is connected to wifi

[Jarrik]

Hi

I have such an irritating problem after last update to Android 7.
I am using Plantronics voyager legend with my phone. And now if it is connected to WiFi I cant hear anything as normally do. Now it is as follows. Phone is connected to WiFi and i am calling. I hear beeps, but when another part answers it just silence. Same happens with incoming calls. Although i can choose to audio source through phone and bac to BT device. Then it works. Or wifi must be off or not connected to any network.

@Jarrik

Did you try to unpair then re-pair with your headset?

[Jarrik]

Yes I've tried it. Also have got info from support center to reset all connections via backup and restore. That doesn't help
By the way, i had same problems while previous version just came up. But later it was fixed....

Would you test if the same happens in Safe Mode?

Everything is ok with for example music sounds or beeps while I am waiting for the answer. Sounds dissappear only when the other person answers. Probably smth with mic activation. And yes it happens only uf wifi is connected. When wifi is on but not connected, everything is fine.

Just tried safe mode. Everything is same.
