If you’re experiencing issues downloading or sending photos, videos, or voice messages, check the following:
If the problem persists, there might be an issue with your SD card. To verify, ensure your SD card has:
Sufficient free storage space. If there is enough space on the SD card, but you still can't download any files on it from WhatsApp, you might need to delete WhatsApp data from your SD card.
Read-only mode turned off.
If none of these solutions have resolved the issue, it could mean that your SD card is corrupted. In this case, you might need to reformat your SD card or purchase a new SD card.
Note: Reformatting your SD card will erase all of the SD card’s content.
