Hi there! I understand your SELPHY Photo Layout app on your iPhone isn't switching to the selfie (front) camera when you try to take selfies. Let me help you sort that out.

First, could you tell me a bit more? When you tap the camera switch button inside the SELPHY Photo Layout app, does it do nothing at all, or does the camera try to switch but then fail? Also, have you tried switching the camera in the iPhone’s native Camera app itself to see if the front camera works outside the SELPHY app?

Meanwhile, here are some straightforward steps we can try to fix this:

1. Restart the SELPHY Photo Layout app: Close it completely (swipe up from the bottom and dismiss the app) and open it again. Sometimes, a fresh start resolves glitches.

2. Check app permissions: Go to your iPhone Settings > Privacy & Security > Camera, and make sure SELPHY Photo Layout has permission to access your camera.

3. Test the front camera outside SELPHY: Open the default Camera app on your iPhone and try switching to the front camera. Does it work normally there? This will help confirm if the front camera is working system-wide.

4. Update or reinstall SELPHY Photo Layout app: If you haven’t already, update the app from the App Store. If it’s up to date, try uninstalling the SELPHY Photo Layout app and then reinstalling it. This can clear any corrupted files causing the issue.

5. Restart your iPhone: A simple reboot can fix unexpected behavior in apps and hardware access.

If after trying these, the app still won't switch to the selfie camera, there might be a more specific issue with the SELPHY app itself. Some users have found reinstalling or switching to the official Canon PRINT app helps, though I understand that might be a different workflow.

Please try these steps, and let me know what you find out with the default Camera app and the SELPHY app switch button response. I’m here to guide you further!
