Hi! Thanks for reaching out about Collectr not recognizing your rear-facing camera on your iPhone running iOS 18.5. To help you better, can you tell me a bit more? For example, does the app display an option to switch cameras at all, or does it only ever use the front camera with no way to change? Also, are other apps on your phone able to use the rear camera normally?

Meanwhile, a common reason the rear camera might not be accessible is due to the app’s permissions or settings. Here’s what we can try step-by-step:

1. Check Camera Permission:
- Go to your iPhone’s Settings > Privacy & Security > Camera.
- Make sure Collectr is allowed to access the camera.

2. Restart the App:
- Close Collectr completely by swiping it away from the app switcher.
- Reopen the app and see if it detects the rear camera.

3. Restart Your iPhone:
Sometimes a simple restart can refresh hardware/software connections.

4. Update the App:
- Check the App Store for any updates to Collectr. A recent fix might be included there.

5. Reinstall the App:
- If nothing changes, delete and reinstall Collectr, which can clear corrupted settings.

6. Test Rear Camera in Other Apps:
- Open the built-in Camera app and check if you can switch to the rear camera without problems.
- If other apps also fail to use the rear camera, this points to a system or hardware issue rather than the Collectr app.

If you’ve already tried these or the problem persists, it’s helpful to know whether this issue started after an update or just suddenly. There was a mention in user forums of a known issue with Collectr related to rear camera usage that was reportedly resolved, but some users still face it1.

Let me know how these steps go, and if needed, I can guide you through more advanced troubleshooting! Are you comfortable trying these?
