Microphone doesn't work on Samsung Fold when it is folded or user is in the background

[Miara]

Describe the bug

• The microphone stops working when you fold the Samsung Fold during a call, but when you unfold the Fold it works again. However, when you start a call with the Fold folded, the microphone works, but when you unfold and fold it, it stops working.
• When the user goes to the background during a call, the microphone stops working, but when they return to the application, it works again. In this case - it always happens regardless of whether the Fold is folded or not.

These bugs appear also in Messenger, but on Whatsapp/Telegram it works properly.

I got report that it also appears on Samsung Note 20. It seems to appear only on devices with Android 13 and 14 in the background. Perhaps microphone service type could solve the issue?

I saw that in this PR: #1200 - you added such service, but only for audio (right?). In PR description it is said that CallService type was changed, but in changes I don't see CallService type has changed. Maybe it would be the solution for the problem mentioned above

SDK version

• 1.0.16

To Reproduce
Steps to reproduce the behavior: actually described above ☝️

Expected behavior
Microphone should work even in the background or folded device.

Device:

• Vendor and model: Samsung Fold 6
• Android version: 14

The issue appears also on Samsung Flip

Hey @Miara thanks for the report.

You can test the theory if the type would work by using the service defined for live streaming host. Its types are "microphone|camera".

To do so you need to provide a CallServiceConfig to the builder like so:

val callServiceConfig = livestreamCallServiceConfig()
val newCallServiceConfig = callServiceConfig.copy(
    callServicePerType = mapOf(
        Pair("ALL_CALL_TYPES", callServiceConfig.callServicePerType.getValue("livestream")),
    ),
)

Supply the newCallServiceConfig to the builder and you would get a service type of microphone|camera.

Let me know if this works. If yes, we will supply a proper default config for this type.

@aleksandar-apostolov I tried, but I have such error - I'm not sure where the problem is:
