How to Fix Webcam Flickering in Microsoft Teams

Identify the symptom and environment

Start by recording when the flicker appears. Note whether it happens only during Teams video calls, in the Teams preview before joining, or in other camera apps as well. Write down the device type, Windows 10 version, camera model, and whether the camera is built in or connected by USB.

Isolate where the fault occurs

Open the built-in Camera app in Windows. If the camera image flickers there too, the issue is likely outside Teams and may involve the camera, connection, or driver. If the image is stable in another app, check whether Teams is using the correct selected camera. Teams can remember a different camera, so verify that the expected input is selected in Teams device settings.

Try reversible fixes in order

Begin with changes that are easy to undo. Close other applications that may be using the camera, unplug and reconnect USB cameras, and try a different USB port if one is available. Avoid connecting through an unpowered hub if the camera behaves unpredictably.

Check camera permission

In Windows Settings, open Privacy and then Camera. Confirm that camera access for the device is on and that Teams is allowed to use the camera. A missing permission usually blocks video rather than causing flicker, but clearing an incorrect state may help after other changes.

Adjust resolution and frame rate

In Teams settings, open Devices and look for camera controls if your version shows them. Otherwise, change the camera resolution or frame rate in the camera manufacturer's control software or Windows camera properties. Lowering the resolution or selecting a standard frame rate such as 30 fps can reduce flicker caused by bandwidth, processing, or automatic exposure conflicts.

Improve lighting

Flicker is often caused by indoor lighting and the camera's automatic exposure. Move the camera position, add steady front-facing light, or reduce strong backlight. If the room has fluorescent or LED lighting, changing the light source or camera angle may change the flicker pattern. This helps identify whether lighting is the main trigger.

Confirm the result

After each change, start a Teams test call or open the camera preview in Teams and watch the image for several seconds. The issue is resolved when the flicker no longer appears in the same conditions where it was first noticed. If you changed lighting, test again in the original room and position to confirm the result.

If the problem remains

Keep notes about which apps, resolutions, frame rates, USB ports, and lighting conditions were tested. If the camera flickers in every app and across those changes, contact the computer or camera manufacturer's support. Do not treat an unresolved symptom as proof of failed hardware; a driver or firmware update from the manufacturer may still be the appropriate next step.
