Hello arushchopra,
Thanks for reaching out to Microsoft Community. I'm sorry to hear about this issue on your camera. I'll do my best to help.
Before anything else, may I know what model of Surface you have? Find out which Surface model you have (microsoft.com).
Normally, update for the Intel AVStream Camera 2500 will be downloaded and installed automatically. It will be listed in the Windows Update history as follows:
Intel Corporation driver update for Intel(R) AVStream Camera 2500 – System – 3.0.0.0.
Kindly check if there are optional updates in Windows Update and if this driver is included.
In the meantime, please also run the Surface Diagnostic Toolkit:
- In the search box on the taskbar, type Surface Diagnostic Toolkit, then select it in the list of results.
If it's not already installed, you can download it from the Microsoft Store. - Follow the on-screen instructions in the Surface Diagnostic Toolkit.
Force a shut down and restart your Surface
- Press and hold down the power button until your Surface shuts down and restarts and you see the Windows logo screen (about 20 seconds), then release the power button.
Let me know how it goes. I'll wait for your response.
