If the camera cannot recognize the memory card, please try the following troubleshooting steps:
1. Try to restart the device to resolve temporary recognizing issues. Power off the camera, wait for a few seconds, and then turn it back on;
2. Ensure that both the camera firmware and the Mi Home/Xiaomi Home APP are up to date. Outdated software can sometimes cause compatibility issues with the memory card;
3. Clear the Mi Home/Xiaomi Home APP's data to let the APP reload and read the data of the memory card;
4. If the issue persists, the memory card can be damaged or worn out. Memory cards have a limited lifespan and can become unusable after many write cycles. Replace the card with a new one from a reputable brand, ensuring it meets the camera's requirements.
