Microsoft Teams Flashes Black Screen When Making a Test Call

Inspiron, Vostro, or Latitude computers may display a black screen flashing when making a test call in Microsoft Teams. Calling any contact in Microsoft Teams does not reproduce the issue.

The step to reproduce the issue is as follows:

1. Flash the latest BIOS and install all drivers.
2. Install the latest Microsoft Teams.
3. Go to Microsoft Teams Settings, then click Devices.
4. Choose Make a test call under Audio devices.
5. A black screen flashes during the test call.

Affected Products:

• Inspiron 13 5330
• Inspiron 14 5430
• Inspiron 16 5630
• Inspiron 16 7630 2-in-1
• Latitude 3340
• Latitude 3440
• Latitude 3540
• Vostro 16 5630

This is an issue within Microsoft Teams and affects only the test call feature in the application.

There is no impact on the use. Microsoft Team does not flash black screen on normal calls.
