Usually communication and file sharing by WhatsApp works very well. However, problems can sometimes arise when you want to download or send photos or other files. The causes can be diverse and range from a lack of Internet connection on your mobile device to a defective memory card.
What to Do if You Can't Download or Send Media Files on WhatsApp
The first thing you can do is make sure your mobile phone is connected to the Internet and has a good signal. You can upload a web page to check it out. Then verify that the date and time are correct. Make sure there is enough free space on the microSD card or the internal memory of the device. Delete some files that you no longer need if necessary. If you have problems downloading files, make sure the microSD card (if your phone has one) is not set to read only. Try to save a non-WhatsApp file. If you do, it means you do not have this setting. Otherwise, change the security settings. If you only have trouble downloading files from WhatsApp, delete some files from the WhatsApp folder on the microSD card. First, make a backup copy of your WhatsApp files and save it to your computer. After that, restart your device. You should no longer have trouble downloading WhatsApp files. If the problem persists, a portion of the microSD card may be damaged. Make a backup of your data and format it.
If, however, the problem continues, replace the card with a new one, as it may be defective.
