If your Echo Show's camera isn't functioning, there are several steps you can take to troubleshoot and potentially fix the issue. Start by ensuring the camera lens is clean and unobstructed. Restart the device to refresh its system. Check if the camera is enabled in the device settings and grant the necessary permissions. Ensure your device is running the latest software updates, as these often contain bug fixes. If the problem persists, try a factory reset, but be sure to back up important data first. If all else fails, reach out to Amazon support for specialized assistance.
