Problems with voice and video calls!

Steps to reproduce

1. Open the Nextcloud Talk app on an Android device (e.g., Xiaomi Redmi Note 12 Pro 5G).
2. Initiate an audio or video call.
3. Wait for the call to connect.

Expected behaviour

The call should connect successfully and the connection should be stable. For context, the exact same setup works perfectly fine when making calls from Windows, Linux, and iOS devices.

Actual behaviour

The call either completely fails to connect or connects with extremely poor video/audio quality. This issue appears to be strictly limited to the Android operating system.

Additional Context / Feature Request

Since it is difficult to troubleshoot this without logs, it would be extremely helpful if a feature could be added to the Talk app allowing users to view and export application logs directly from the app's interface.

Start by reproducing an audio and video call in the native Android Talk app on the reported Xiaomi Redmi Note 12 Pro 5G setup, using the configured signaling, TURN, and STUN servers. Compare the failed or degraded call with the working Windows, Linux, and iOS cases, and collect application logs; done means the Android call behavior is explained and a reproducible fix or diagnostic result is documented.
