Apple watch camera remote not working

Hello giriraj2151,

​Thank you for using the Apple Support Communities. It looks like you're running into an issue with the Camera Remote on your Apple Watch, and we'll be happy to help out. We see you've already tried re-downloading the app, which is a great step.

As a test, does the issue persist if you try all of these options? Use Camera Remote and timer on Apple Watch

"Choose a different camera and adjust settings

1. Open the Camera Remote app  on your Apple Watch.
2. Tap , then choose from among these options:

• • Timer (3-second timer on or off)
  • Camera (front or rear)
  • Flash (auto, on, or off)
• Live Photo (auto, on, or off)
  • To see which devices support Live Photos, see the iPhone User Guide.
  • HDR (on or off)"

If so, we recommend that you get in touch with Apple directly: Get Support

Take care.
