i can not reproduce this.

@jancborchardt reported some behavior that may be related:

> The bluetooth device is not picked by default as an output (unlike for other apps like VLC, Youtube, phone, etc)
Even when picked, it still seems to go via the phone speaker?
Then at some point also the entry "Bluetooth" went missing again in the list.
I force closed the app and tried again multiple times, same result always

I will get a device with android 14 soon and then will test if it's because of the android version.

When i have the device i will also have a closer look at https://developer.android.com/about/versions/14/behavior-changes-14#enforce-bluetooth_connect

Just for the record, I don’t even get any sound on the bluetooth initially. It is shown in the device selector first, and then vanishes.

just came by when debugging an other issue.. The if check in

https://github.com/nextcloud/talk-android/blob/ea2bebe3b0f91b61147822e51cfecbf7baa0bc51/app/src/main/java/com/nextcloud/talk/activities/CallActivity.kt#L346-L350

must be removed or logic must be different. That's why there could be no dialog to explain why bluetooth is necessary..

got the android 14 smartphone but can't reproduce the issues 😕 So it's maybe not related to android 14.

If you have bluetooth devices, can you try to reproduce @sowjanyakch @rapterjet2004 ?

I will make a few more tests. I have a Jabra headset and a Sennheiser and see if it might have been fixed with the latest android patches.

I could not reproduce this issue on my Samsung A52 (Android 14) and pixel 6a (Android 14)device.

For me on Android 15 on a pixel 7 pro and a jabra headset it got disconnected and bluetooth option varnished completely
