Bug description

When connected to a headset and I answer a call, Bluetooth works. If switch to speaker and then back to Bluetooth, the call stays on speaker. I have to hang up and call again to resume Bluetooth connectivity.

I'm using Google buds 2. Had the same issue with Google buds 1, and a Bose QC3 headset. Same issue happened with my Pixel 3 XL and now this Pixel 4 XL. Could be Pixel specific, I haven't tried another Android phone.

Steps to reproduce

• connect Bluetooth headset
• call someone
• talk on Bluetooth for a few seconds
• click speaker icon
• talk on speaker for a few seconds
• click the Bluetooth icon

Actual result: Describe here what happens after you run the steps above (i.e. the buggy behaviour) The call stays on speaker even though the Bluetooth icon is selected.

Expected result: Describe here what should happen after you run the steps above (i.e. what would be the correct behaviour) The call should switch back to the Bluetooth headset.

Link to debug log

I tried to do this but it said "failed to submit debug log". Tried to copy/paste manually but no option to do so.

With 4.60.8 there was a new commit for bluetooth behavior. Does this solve the problem for you?

Yes it did thank you, though I found a new issue with switching when connected to multiple devices. So if I'm in the car and I have both my headset and car connected, I can't seem to switch between bluetooth devices. I'll raise a new ticket
