Bluetooth Audio delay when answering calls

[AC Question]

My LG G4 died recently so I have now moved over to the ZTE Axon 7 Mini. Great phone for the price but when using bluetooth to answer or make calls there is always a 5 second delay when the audio is coming from the phone and is then passed onto the bluetooth device.

This is strange as the I use the bluetooth device to answer the call which shows the number straight away. This never used to happen with any of my other Android devices. I've tried several bluetooth devices, and also deleted and repaired devices. Still the same issue.

Any ideas?

Thanks,

New phone? Isn't working right? Get another one. (You don't try to fix someone else's problems.)

What software build is on your phone? Is it B21? If it was on a store shelf for a while, it might not be. I had a similar issue that went away after I updated to B21.
