If it prompts that the SD card cannot be formatted or repeatedly prompts to format, please refer to the following methods:
1. Please use a memory card specifically designed for cameras by reputable manufacturers;
2. The camera only supports memory cards between 16GB and 256GB;
3. After tapping format, please be patient and wait for the process to complete;
4. Avoid frequently hot-swapping the memory card. Always power off the camera before inserting or removing the memory card, as frequent hot-swapping can degrade the performance of the memory card and cause issues;
5. Try restarting the device and attempt to format again;
6. Check if the camera firmware and the Mi Home/Xiaomi Home APP require updates;
7. Replace the SD card;
8. If you cannot format the SD card in the APP, you can use a card reader to format the memory card on a computer. After formatting, power off the camera and reinsert the card.
