Microsoft fixes the bug breaking calling on Surface Duo 2

The December 2022 firmware update is now available for the Surface Duo 2, delivering traditional Android monthly security updates. It also fixes one device-specific bug that has been annoying some Surface Duo 2 owners since the release of Android 12L by sending incoming calls directly to voicemail and breaking outgoing calls.

What is new in the December 2022 update for the Surface Duo 2?
