Hi Wear team!

I'm having huge issues with "Play phone voice call on watch" on my Pixel 2 XL and Huawei Watch 2 (AW2.7) where apps (Phone, Duo, WhatsApp - anything that uses a BT headset) freeze for 10-15s after making or receiving a call on the phone with the watch connected.

Looks like audio is auto-redirected to the watch when it shouldn't and watch isn't ready resulting in no audio/mic at all

Apps usually unfreeze (or not) after 10-15s and audio is then randomly routed to watch speaker or the handset speaker, but by that time most callers have already disconnected (cause neither mic nor speaker is working and they assume nobody is on the other side of the phone)

On top of that, changing the in-call audio output to speaker doesn't seem to work or persist and Android is trying to route the next call to the watch again - which results in freezes again.

Only solution for now is disabling the feature (which disables the "Phone calls" BT capability on the watch) - but this was one of the crucial features I bought this watch recently for. Could we please try to work this out?

Below is some extra info from a post I made on one of community forums:

How I understood it would work:

    Calls made/answered on the phone would be heard on the phone (or it would at least remember the last selection)
    Calls made/answered on the watch would be heard on the watch
    I would be able to transfer the call between my phone/watch (over BT) during the call the same way I do for other BT headsets/speakerphone

How it works for me:

    Calls made from the watch work fine and are heard on the watch
    Calls made from the phone don't work fine:
        The Phone app will lag and freeze for ~5-10s during which nothing is heard on any speaker. When it unfreezes time counter jumps to correct time (e.g. 0:07) which confirms the call was actually underway
        OR it won't lag but nothing is heard on the phone /watch speaker anyway, regardless of which was auto-selected by Android

    When this happens, switching outputs doesn't work: Watch (BT), Speaker, Phone's headphone - there's only silence on all of them

    When this happens, the default device in the Phone can indicate either a BT device or the phone speaker, but both remain silent.

    Sound will come back after 10-15s on either watch or phone. If on the phone, there's a "pop" in the earphone right before it comes back

Receiving and making calls in Duo, WhatsApp, Hangouts results in the same - lagginess and no audio at all until I disconnect the watch and make the call again. Apps will also freeze for about 5-15s every time I try to switch to BT audio (no sound at all) and then unfreeze and switch back to phone audio
