Camera Flickering Still

I am having the same issue!  Tried the same fixes. Was told it is a Camera App issue. 

I spent time with customer service at Logitech and we reinstalled the camera app software.  We also tested it on other apps and the camera was fine.  In fact, this camera worked fine for the first 6 weeks or so and the started flickering.  Definitely seems like a Zoom issue.

If you're on Windows 11 here is a fix that will work and will not require any extra software.
In windows search, search for Camera app >> Click the top left Cog (settings cog) >> From the drop down click  Video Settings >> Flicker reduction >> Change the setting from 60Hz to 50Hz or vice versa and your flicker should be gone.

The method I have described is shown here with screenshots (Method 2 of 5)
