The situation when WhatsApp sends a notification about a new message, but when you click on the attachment you see endless loading or the error “File not found" is familiar to many Android users. This problem can occur suddenly, even if the messenger previously worked without failure, and it often blocks the receipt of important documents or photos.
The reasons for this system behavior vary from a simple lack of disk space to complex access rights conflicts after updating the operating system. In this article, we will analyze in detail why files cannot be opened in WhatsApp on Android, and we will offer a step-by-step algorithm for troubleshooting without losing correspondence.
Most often, the problem lies in the fact that the application has lost connection with the file system or cannot write data to the internal memory. Understanding the mechanism of operation of caching and access rights will help you quickly diagnose a failure and restore functionality to the messenger.
Lack of free space and system limitations
The most common reason why media files stop downloading or opening is a critically low amount of free memory on the device. Android requires buffer space to temporarily process data before storing it in permanent memory.
When storage is more than 90% full, the system blocks writing new files to prevent other applications from crashing. In this case, WhatsApp may show a loading message, but the actual process will never complete successfully.
Check the memory status in your phone settings. If there is less than 500 MB of free space, you must free up space immediately. Delete old videos from the gallery, empty the trash, or transfer large files to your computer or cloud storage.
- 🗑️ Delete the cache of heavy applications such as YouTube, Instagram or TikTok through the system settings.
- 📸 Move the archive of photos from the past year to an SD card or to the Google Photos cloud.
- 📥 Clean out the Downloads folder, where APK installation files and old documents often accumulate.
⚠️ Attention: Do not try to delete system files or folders with unknown names in the root of the internal memory. This can lead to unstable operation of the smartphone and the need to completely reset the settings.
ℹ️ The settings menu interface and the location of memory clearing items may differ depending on the model of your smartphone (Samsung, Xiaomi, Pixel) and the version of the manufacturer's shell. Check the official user manual of your device.
Problems with permissions and access to storage
Starting with version Android 11 and higher, Google's security policy has tightened the rules for application access to the file system. Now messengers cannot freely read and write files in shared folders without the user’s explicit permission.
If, after updating your operating system, your files no longer open, it is likely WhatsApp lost rights to access the storage. This often happens during system crashes or after manually changing privacy settings.
To correct the situation, you need to manually check the permissions issued. Go to your phone settings, find the “Applications” section, select WhatsApp and go to the “Permissions” menu. Make sure that the switch next to “Files and media content” or “Storage” is active.
Some shells, for example MIUI or OneUImay have additional restrictions. Check to see if you have a Security or Privacy mode enabled that blocks access to certain folders for selected apps.
If the permission is already enabled, try turning it off, restarting your phone, and then turning it on again. This will forcefully update the access configuration for the system.
Failure of the WhatsApp application cache and data
The accumulation of errors in temporary application files is another common reason why photos or documents do not open. Cache Designed to speed up work, but if it is damaged, it begins to interfere with correct display content.
Clearing the cache is a safe procedure that will not delete your correspondence, but will reset temporary interface settings and downloaded previews. This is the first action that should be performed when boot errors occur.
Perform cleaning through the system menu: go to Settings → Applications → WhatsApp → Storage. Click the Clear Cache button. Do not click “Clear data” if you do not want to delete your entire message history and account settings.
If clearing the cache did not help, the media file index itself may be damaged. In this case, you may need deeper diagnostics or reinstalling the application with a preliminary backup.
☑️ Diagnosing memory problems
Network errors and connection settings
Files cannot be opened if they are not physically downloaded to the device due to problems with the Internet connection. Even if the Wi-Fi icon is active, the actual data transfer speed may not be sufficient to download “heavy” videos or documents.
Often the problem lies in the settings of the messenger itself. W WhatsApp here is a function that limits auto-downloading of media only when connected to Wi-Fi. If you are trying to open a file via a mobile network and permission is not given, the download will not start.
Check your startup settings. Go to Whatsapp settings → Data and storage. In the “Auto-download media” section, make sure that the required file types are selected for “Mobile network” and “Wi-Fi” (Photo, Audio, Video, Documents).
| Connection type | Possible problem | Solution |
|---|---|---|
| mobile data | Traffic limit or weak signal | Allow downloading in settings or go to the window |
| Wi-Fi network | Blocking ports by provider | Switch to mobile network to check |
| VPN service | Low tunnel speed | Temporarily disable VPN and try again |
| Airplane mode | Complete lack of connection | Turn off airplane mode and restart the network |
Using VPN or proxy servers can also block the connection to media download servers. If you use such tools, try disabling them while the file is downloading.
File corruption or problems on the sender's side
Sometimes the problem is not with your phone, but with the file itself. If the sender was using an unstable connection at the time of sending, the file may have been partially downloaded to the server or may have been damaged during encoding.
In this case, no matter how many times you try to open the attachment, the system will display a format error or a data corruption message. This is especially true for large video files and archives.
Ask the other person to resend the file. You can also ask to send the document not as “Photo” (with compression), but as “Document” (without compression), to eliminate conversion errors on the server side.
⚠️ Attention: If the file comes from an unfamiliar number and does not open, do not try to install third-party codecs or apps to view it. This could be a virus disguised as a document.
How to check the integrity of a file?
Try opening the same file on your computer via WhatsApp Web. If it opens normally on a PC, then the problem is in your phone’s settings or memory card. If the file is broken on the PC, there is an error on the sender’s side.
Outdated version of the application and software conflicts
Developers regularly release updates for WhatsApp, fixing vulnerabilities and adding support for new file formats. An outdated version of the messenger may not work correctly with new types of attachments or conflict with the current version Android.
Check for updates in the store Google Play Market. If the Update button is active, be sure to install the new version. In rare cases, completely reinstalling the application helps.
Before deleting, be sure to create a backup copy of your chats. Go to Settings → Chats → Chat backup and click “Backup”. After that, delete the application, restart the phone and install WhatsApp again.
Conflicts can also arise with third-party antiviruses or memory cleaners that mistakenly block the operation of the messenger. Try temporarily disabling third-party security software.
Regularly updating applications through the official store is the best prevention of compatibility errors and problems with opening files of new formats.
Specific errors of the SD card and saving paths
If you have configured saving media files to a memory card microSD, the problem may be related to it. The card could be damaged, go into read-only mode, or simply be slow, causing a timeout when trying to write.
Try changing the save path to the phone's internal memory. In the settings WhatsApp find the “Storage” item (if available) or in the phone settings change the default recording disk.
Remove the memory card, wipe the contacts and insert it back. If the error persists, check the card on another device or through a computer. The file system of the card may be damaged and require formatting.
- 💾 Formatting the memory card will delete all data on it, so first save important files on your computer.
- 🔌 Use a quality card reader to check the SD card for bad sectors.
- 📁 Make sure that The folder
WhatsApp/Mediais not hidden or password protected via the file manager.
Frequently asked questions (FAQ)
Why does a WhatsApp video show a black screen instead of an image?
This indicates a problem with the codec or file corruption. Try opening the video through a third-party player, for example VLC. If there is a black screen, the file is not fully downloaded or damaged by the sender.
Is it possible to recover files that did not open and were deleted?
If the file is not downloaded completely, it cannot be restored. If it was downloaded, but you accidentally deleted it from the gallery, check the folder .Statuses or use applications to recover data before the memory is overwritten.
Why do files open on one phone, but not on another?
Differences may be in the version of Android, the presence of necessary codecs, the amount of free memory, or access rights settings. An older version of the OS may not support new image or video formats sent by the other party.
How to open an .apk file sent to WhatsApp?
APK files are application installers. To install them, you need to allow installation from unknown sources in your phone's security settings. Be careful: install such files only from trusted senders.
What to do if it says “File not found”, although it is in the chat?
This means that there is a link to the file in the messenger database, but there is no physical file at this path on the disk. It may have been deleted by a memory cleaner or moved. Try asking to resend the file again.
