When you open a standard gallery on your smartphone and find that a significant portion or even all of the images have disappeared, it causes panic in any user.More often than not, the files are not physically gone, but simply stopped showing due to a malfunction of the system scanner media or a change in the logic of sorting after updating the operating system MIUI or HyperOS. Owners of Xiaomi, Redmi and Poco devices regularly face this, especially after installing fresh security patches.
Before you start to manipulate the file system, you need to understand the nature of the problem. The disappearance of thumbnails or entire folders is often due to the fact that the indexer lost connection with the real location of the files on the disk, this can occur due to incorrect termination of the application, cache overflow, or conflict between the built-in application “Gallery” and third-party services like Google Photos.
In this article, we will go into detail all the possible reasons why your images may have been missing and offer step-by-step instructions for returning them. We will look at both software errors and human factors, including accidentally moving data to hidden partitions or cloud storage. A critical first step is to check the folder.thumbnails and hidden albums, since 80% of the time the files are located there.
Hidden albums and system display filters
The first place to look when looking for missing images is the settings of the app itself. There is a hide-album feature in the MIUI and HyperOS shells that is often activated by accident when you clean the screen or swipe, and if you accidentally hide a folder with important photos, it will disappear from the general list, but will remain available through a special menu.
To check, tap and hold your finger in the empty space of the album list or find the appropriate item in the display settings. There may be hidden system folders like Screenshots, Downloads or albums from social networks, and it is worth checking whether the "Favorites Only" mode or the date filter that could cut off old photos from viewing is turned on.
Another reason could be a cloud sync failure: If you have sync enabled with Xiaomi Cloud or Google Photos, the app can only show previews or hide originals to save space. Check your download quality settings and make sure that all files stored both on-premises and in the cloud are displayed.
It's important to distinguish between hidden albums and password-protected albums, and if a device has a privacy password, certain folders can be completely blocked without entering the code, in which case the standard gallery interface will not show this data.
Media file scanner malfunction and cache cleanup
One of the most common technical reasons for a photo to disappear is a failure in the Media Storage system component, which is responsible for scanning internal memory and creating a thumbnail database, and if its database is damaged, the gallery simply cannot see the files, even if they are physically on the disk.
To remedy this, you have to do a forced cleanup of the scanner data, which is a safe procedure that won't delete your photos, but will only make the system scan your memory again. Go to your phone's settings, find the Apps section, and select All Apps. From the list, look for Media Service or Media Storage.
Inside the app menu, click on the Clear button and select Clear All Data or Clear Cache. After that, be sure to restart the device. The re-scanning process can take anywhere from 5 to 20 minutes depending on the storage capacity, at which time the phone may get slightly warm, which is normal.
☑️ Algorithm of resetting the scanner of media files
If the photos didn't appear immediately after the reboot, let the phone lie on the charger with the lock screen on for 10-15 minutes. The system often conducts deep indexing during downtime. Don't try to actively use the phone at this time, so as not to interrupt the process of indexing files.
Problems after updating MIUI or HyperOS
Updating the operating system is always stressful for the file structure. MIUI or HyperOS, the paths to some system folders may change, for example, new versions of Android and Xiaomi shells have tightened the rules for accessing the folder. Android/data, Some apps have stopped seeing the images stored there.
Often, the permissions for the Gallery application are lost after an update. It may lose permission to read internal memory. Check permission settings: go to Settings → Apps → Gallery → Rights and make sure that access to Photos and Videos or Multimedia Files is allowed.
If you upgrade from MIUI 13 to MIUI 14 or HyperOS, the old Gallery app may not work properly with the new file system, in which case it helps to remove updates to the Gallery app itself or completely reinstall it through the GetApps store.
⚠️ Warning: After a major system update, it is not recommended to immediately clear the phone's memory with third-party utilities. 1-2 Optimize your background processes, otherwise you can damage newly created index files.
In some cases, the problem lies in the file system format. If the phone was previously used with another OS or was subjected to deep modifications, the update could lead to partition reading errors. However, for ordinary users, this is rare, and most often the problem is solved by rechecking the access rights.
Conflicts with Google Photos and Cloud Services
Modern Xiaomi smartphones often offer to use Google Photos as the main gallery. If you accidentally agreed to this or updated the application, media management could go to Google services. In this case, your photos can be displayed in the Google Photos app, and the standard Xiaomi gallery will be empty.
Check to see if Google Photos’ Free Space feature is enabled, which removes local copies of photos that have already been uploaded to the cloud, leaving them only on the Internet. If there is no internet, these photos will not be visible in the phone gallery.
Another scenario is desynchronization of accounts, if you changed your password or logged out of your Google account, the sync might have stopped and the new photos didn't make it to the common database. Check your account status under Settings → Accounts and Sync.
| Service | Where to find a photo | Risk of removal | Internet is required |
|---|---|---|---|
| Xiaomi Gallery | Locally on the device. | Low. | No. |
| Google Photo | Cloud + Cash | Medium (liberation function) | Yes (for the cloud) |
| Xiaomi Cloud | The Mi cloud | Low. | Yes. |
| File manager | DCIM/Pictures folders | No. | No. |
What is a folder.thumbnails?
Checking the file manager and hidden folders
If the gallery is empty, but you're sure the photos haven't been deleted, you need to check the physical presence of the files through the file manager. Open the File Manager app and go to the DCIM folder. This is where the camera snapshots are stored as standard.
Inside the DCIM folder, find the Camera folder. If your photos are in place, then the problem is purely software in the Gallery app. If the folder is empty, check if the system file hiding mode is enabled in the Explorer. Click on the menu (three dots) and select Settings, then activate the hidden files display.
It is also worth checking for a.nomedia file. This is a special empty file that prevents the system from scanning it for media files. If such a file appears in the photo folder (often done by messengers or cleaning programs), the gallery will stop showing the contents of this directory. Deleting the.nomedia file will return the images to the view.
💡
Use extension search. In the file manager, type in search for "jpg" or "png" to show all the graphics files on the device, regardless of which folder they are in, and it will help you to understand whether the files themselves are whole.
Remember to check the card if it's installed. Sometimes the card's counting device fails and the phone temporarily stops seeing the card's contents. Try extracting the card, erasing the contacts and pasting it back, or checking it through the computer.
Recovery from the basket and backup copies
Perhaps the photos were deleted accidentally, and you just didn't notice this point. In modern versions of MIUI and HyperOS, deleted files don't disappear immediately, but move to the Recycle Bin. This album is stored in the Gallery app and is usually available for 30 days.
Open the Gallery, go to the Albums tab, and scroll to the bottom, and you'll find Deleted. If your photos are there, highlight them and click Restore. They'll go back to their original albums.
If you don't have a photo locally, check your cloud backups. Go to your Mi Account settings and select Cloud. You can have a synchronized copy of your gallery there. Similarly, check photos.google.com -- maybe sync with Google was successful, and the originals are there.
⚠️ Warning: Do not write new large files (movies, games) to your phone if you expect deep data recovery. New information can overwrite the memory sectors where your deleted photos were physically located, making recovery impossible.
For cases where photos are critically important and are not found in any of these locations, there are specialized computer-connected data recovery software, but their effectiveness depends on the time elapsed since the deletion and the activity of the phone after the incident.
💡
Systematic check of the cart and cloud services restores up to 90% of the “lost” photos without using complex software.
