My side button is not working for click photos in my iPhone XR

Greetings tejal32,

Thanks for visiting the Apple Support Communities! It seems the side button isn't working for taking a photo with your iPhone.

You can use either volume buttons, but not the side button to take a photo. Check out that information in the article below:

iPhone camera basics - Apple Support

"Take a photo or video

Tap the Shutter button, or press either volume button to take a photo."

Kind regards.

Hi tejal32,

Thanks for clarifying the issue. It sounds like there may be a hardware issue with the device. Reach out to Apple Support, or seek service for further assistance with diagnosing the behavior. The article below will help you with those steps:
