Thank you for the update. I recommend starting with the suggestions provided in the AI Answer, as they cover the most common causes of camera error 0x80004003 on a Surface Pro 7. Please let me know how it goes after trying those steps.
If the issue continues, I have a few additional checks that may help narrow down the cause:
- Test the camera in other applications
Please check whether the issue occurs only in the Camera app or across all applications. For example, try using the camera in Microsoft Teams, Zoom or a browser-based video call.
- If the camera works in other apps but not in the Camera app, this may indicate an issue specific to the Camera app.
- If the camera fails everywhere, it may point to a driver, device or hardware-related issue.
- Test from a new Windows user account
Sometimes camera issues can be related to corruption within a specific Windows user profile.
To test this:
- Go to Settings > Accounts > Other users.
- Select Add account.
- Choose "I don't have this person's sign-in information" > "Add a user without a Microsoft account".
- Create a temporary local account and sign in to it.
- Once signed in, open the Camera app and check whether the camera functions normally.
If the camera works in the new account, that suggests the issue is related to your current Windows profile rather than the camera hardware itself.
- Verify whether the camera is detected in Device Manager
Please open Device Manager and expand the Cameras section.
Let me know what you see:
- Is the camera listed normally?
- Is there a yellow warning icon next to it?
- Is the Cameras category missing entirely?
A screenshot of Device Manager would be very helpful, as error 0x80004003 can sometimes occur when Windows is unable to properly detect the camera device.
- Check the camera setting in Surface UEFI
The Surface camera can be disabled at the firmware level.
To verify:
- Shut down the Surface completely.
- Press and hold Volume Up, then press and release the Power button.
- Continue holding Volume Up until the Surface UEFI screen appears.
- Navigate to Devices and confirm that the camera is enabled.
- If you make any changes, save them and restart Windows.
Please keep me updated on the results of these checks, especially whether the camera is visible in Device Manager and whether it works from a new Windows account. That information will help determine whether we're dealing with a profile issue, a device detection problem or a potential hardware fault.
I look forward to your update.
