Modern smartphones store a huge amount of personal information, and Xiaomi Mi 9 is no exception. Device owners often face the need to protect certain photos or videos from prying eyes, whether they are curious friends or children. The standard gallery MIUI offers a built-in tool to solve this problem, which hides content from public access.
The hidden album function works at the file system level, moving selected media files to a secure memory area, which means that you can’t see them through Explorer or third-party apps without authorization. In this article, we’ll detail how you activate protection, set passwords, and manage hidden files on your device.
Using Xiaomi’s built-in security features is preferable to installing third-party apps, as the system tool has deeper access rights and is better integrated into the shell. You get the opportunity not only to hide photos, but also to encrypt them, making them available only after entering. PIN-This creates a strong barrier to unauthorized access to your personal data.
Preparing the device for setting privacy
Before you start creating a hidden storage, make sure your device is ready to handle sensitive data.The Xiaomi Mi 9 comes with a Mi Account, which is often required to synchronize security settings.
It’s also worth checking if the latest version of the MIUI shell is installed.Developers periodically release security updates that may affect gallery operation and data encryption.Go to the settings menu and select About Phone to check for updates.
It's important to understand that a hidden album is not just a folder, it's encrypted space. If you forget your password or lose access to your Mi Account, it's extremely difficult to recover data, and in some cases impossible, so it's recommended that you back up important files on a cloud drive or computer before you start setting up.
☑️ Preparation for the setup of a hidden album
Activation of the hidden album in the Gallery
The process of enabling file hiding in Xiaomi smartphones is implemented through a hidden gesture in the Gallery app. Open the standard photo viewing app. You need to go to the Album tab, where all your image folders are displayed.
When you're in album list view mode, swipe down from top to bottom across the screen. This action activates the hidden menu. If you're doing this for the first time, the system will prompt you to create a new hidden album. Press the appropriate button to start the procedure.
Once activated, the system will require you to set a security method, you can choose to enter a password, a pattern lock, or use a fingerprint if it is configured in the system. Biometric protection significantly speeds up access to hidden files, but requires you to pre-configure in the security section of the device.
⚠️ Warning: Don't use simple combinations like "1234" or "0000." A hidden album is designed to protect you from curiosity, and weak defenses can be easily bypassed.
Once you set the password, you'll see a message that you've made the album successfully, and now, if you re-run the top-down section of the albums, you'll be able to access this secure space, and all the activities inside of it are isolated from the main gallery.
💡
Use different passwords to lock the screen and for a hidden album, which will create an extra layer of security in case someone knows the unlock code for your phone.
Setup of protection methods and passwords
The security of your data depends on the complexity of the password you choose. There are several authentication options available in the Xiaomi Mi 9, you can use a digital code, a pattern lock or biometrics, and it is recommended to combine methods for maximum protection.
To manage passwords, go to the security settings, where you can change your existing code or add additional login methods, and the system also allows you to link access to your Mi Account, which can help restore access in the event that you forget your password, although this feature does not work in all regions.
Special attention should be paid to the visibility setting, which in some versions of MIUI can hide the existence of a hidden album, making it possible only by entering a special code in the dial or using a certain gesture, which turns the album into a real digital safe.
- 🔒 pattern lock: easy to remember, but can be seen by the traces on the screen.
- 🔢 Digital. PIN: Classic method, it is difficult to peek from the side if you close the screen with your hand.
- 👆 Fingerprint: The fastest and most reliable way, but requires a biometrics setup.
- 👤 Mi Account: Recovery of access via cloud, but requires Internet access.
Transferring photos and videos to a hidden album
Once the repository is created, you can move files into it. There are several ways to do this. The easiest way to do this is to open a regular photo in the gallery, click on the menu (three dots or icon "More") and select the option to Hide or Add to a hidden album.
An alternative method allows you to move groups of files at once. In grid view, press your finger on one photo, then highlight the remaining images. In the bottom menu that appears, find the move button, which is especially useful when you first sort the archive.
When moving files are physically copied to a secure area and the originals are removed from public access, it is important not to interrupt this process, especially if you are carrying heavy video files in high resolution 4K. Interrupting can lead to file corruption.

Content management and file recovery
Managing files inside a hidden album is not much different than working with a regular gallery, except for the need for permanent authorization. You can view, delete or edit images. However, editing functions may be limited for security reasons.
If you need to return a photo to the public, open the hidden album, select a file and click Remove from the hidden album or Restore.The file will return to the original folder or the gallery root, becoming visible again for all applications.
It is worth noting that deleting a file from a hidden album without restoring it leads to its irretrievable disappearance.The basket in a hidden album may work differently or not at all, so be careful when clearing this space.
| Action. | Location of file | Availability |
|---|---|---|
| A typical photo. | Gallery/DCIM | Seen by all applications |
| Hidden photo | System storage | Only after the password. |
| Deleted photo | Basket (30 days) | Recoverable. |
| Remote from the hidden | Unavailable | Irreversible. |
⚠️ Warning: When you reset your phone to factory settings, the contents of the hidden album are deleted along with the rest of the data. Unload important files in advance if you plan to flash it back.
Solution and technical nuances
Xiaomi Mi 9 users may experience a situation where a hidden album stops opening or disappears after a system update. Often this is due to a change in MIUI security policy or errors in the Gallery app cache.
Another common problem is password desynchronization, and if you change your screen unlock password but you don't update your hidden album password, you can be blocked. Always sync that data in your security profile.
In some cases, files may be lost if the system is power saving mode or third-party memory cleaners aggressively unload the gallery processes.
💡
Hidden album on Xiaomi is a software solution that depends on file system integrity, and regular backups are the only way to ensure data is safe in case of failure.
Understanding the principles of hidden storage allows you to effectively manage personal space on your smartphone. Xiaomi Mi 9 provides powerful tools for this, but requires the user to be careful and responsible for the safety of access keys.
