Modern smartphones like the Xiaomi Redmi Note 9 are becoming a repository of vast amounts of personal information. Among the thousands of snapshots are often documents, passport scans or just personal photos that are not intended for prying eyes. The standard gallery, which opens when you unlock the screen, is available to anyone who picks up your phone.
Fortunately, MIUI provides powerful privacy protection tools that don’t require any additional software. In this article, we’ll take a look at all the ways you can hide images by turning your smartphone into a safe, and not only the standard features, but also the nuances that can help you avoid accidental data leaks.
Many users are unaware that their device has hidden partitions that are protected by a special password, and we will look at the mechanism of the Hidden Album, its integration with the cloud and the file manager, which will allow you to choose the most convenient option for managing confidential content.
Use of the built-in Hidden Album
The most effective and safest way to remove images from outsiders is to use the regular Hidden Album feature, which is built directly into the Gallery app and works at the system level, providing a high level of protection, and the photos moved here disappear from the shared tape and become visible only after authorization.
To activate this feature, you need to do a few simple steps in the application interface. It is important to understand that access to this partition is protected by the same privacy password that is used to hide applications or protect personal notes. If you have not previously installed such a code, the system will prompt you to do so on the first login.
The process of concealment is as follows:
- 📱 Open the Gallery app and go to the Albums tab".
- 👆 Pull the album list down until a castle icon with the inscription "Hide the album" appears".
- 🔐 Enter the previously set unlock password or use a fingerprint.
- 📁 Press the button "+" in the corner to add photos from the main gallery.
⚠️ Note: When you move a photo to a hidden album, the originals are removed from public access. If you forget the privacy password, it will be extremely difficult or impossible to restore access to these files without a Mi Account.
There's an extra layer of security inside the hidden album, and you can set a separate password for that folder, different from the main unlock code of the device, which creates a double security barrier, which is especially true if you're using a phone by your kids or your coworkers.
Configure the privacy password and biometrics
The foundation of security in Xiaomi Redmi Note 9 is the right setting of privacy settings. The system allows you to use not only a pattern lock or a digital code, but also biometric data. The fingerprint scanner located on the side of the face works instantly and makes access to hidden photos as convenient as possible.
To configure access options, go to Settings → Passwords & Security → Privacy. Here you will see a list of all the protected items, including the hidden album. Make sure the switch opposite the desired function is activated. This is where the type of protection that will be requested when you try to log in is set.
It is recommended to use complex combinations for the pattern lock: simple shapes like the letter "G" or a straight line are easy to peek from the side, and the system allows you to configure the display of the password on the lock screen so that outsiders do not see which partition you open.
☑️ Security setting
Biometrics is a lot faster, but it has limitations, and if your finger is wet or dirty, the system may not recognize your fingerprint the first time, and in such cases, you need to remember the backup digital or graphical code, and you should also consider that once you reboot your device, the biometrics don't work until you first manually unlock your master password.
Hiding files through Explorer
An alternative method that is often overlooked is System Explorer, which, unlike a gallery, hides files at the file system level, making them invisible to most applications, including instant messengers and social networks, which is especially useful if you want to hide not only photos, but also videos or documents.
To access this feature, open the Explorer app and swipe down the screen, similar to the gallery action, and you'll see a privacy password request. Once you type in, you'll be taken to a hidden folder where you can move any files, and the way you work here is identical to the hidden album, but covers all types of data.
The advantage of this method is that the files hidden here do not take up space in the cache of the gallery and are not indexed by the media search system. However, it is worth remembering that when you clear the cache or reset the settings of the Explorer application, access to this data can be difficult without prior backup.
| Method | Type of data | Level of protection | Availability |
|---|---|---|---|
| Hidden album | Photos, Videos | High-pitched | Only through the Gallery. |
| Conductor | Any files. | High-pitched | Through the Conductor |
| Second space | All data. | Maximum | Separate profile |
What happens to metadata when hidden?
Use of the Second Space
For users who want maximum data isolation, Redmi Note 9 offers a Second Space feature: It's not just a folder, but a full-fledged second profile on Android. It has its own desktop, its own apps, its own Google account and, most importantly, its own galleries and files.
Switching between the main and second spaces is instantaneous through settings or a special widget, so you can set different fingerprints to enter different spaces, for example, the thumb of the right hand opens a personal profile, and the left one opens a work or guest profile.
This solution is ideal for situations where the phone may need to be unlocked during a check or when the device is used by a child. In the second space, there will simply be no apps and photos that are in the main profile, which creates the illusion of a clean device.
⚠️ Note: The second space takes up additional memory on the disk, as some system resources are duplicated. On models with a small amount of internal memory (for example, 64 GB), this can become critical.
The second profile takes time to set up, you have to log in to the apps you need, but the level of privacy you get is totally worth the effort, and it's actually two phones in the same case.
💡
Use different wallpapers for the main and second spaces to visually distinguish which profile you are currently in, and this will prevent the accidental sending of personal photos from the protected profile.
Third-party applications for photo protection
If there's not enough built-in tools, Google Play offers a lot of alternatives, and what's known as "safe calculators" are popular, and these apps look like a calculator, but when you type in a special code, they open up a hidden gallery, and it's just a standard utility for an outsider.
Another class of software is file encryptors, which don't just hide photos, they encrypt their contents, and even if an attacker copies a file to a computer, without a password, they'll only see a set of unreadable characters, such as KeepSafe or Gallery Vault.
However, using third-party software carries risks, and developers of such applications may have access to your data, and if you reset your phone or remove the safe application, photo recovery may not be possible without cloud sync, which not all services support for free.
When choosing an application, pay attention to:
- 🛡️ Local encryption without mandatory upload to the cloud.
- 📉 Number of advertisements and suspicious permits.
- 📅 Date of last update by the developer.
- 👥 User reviews about the reliability of data storage.
Cloud Solutions and Synchronization
The modern approach to security involves not only hiding, but also backing up. Google Photos and the Mi Cloud allow you to delete photos from the device, leaving them available only over the Internet after authorization. This frees up the memory of the Redmi Note 9 and protects data in the event of loss of the phone.
Google Photos has a "Blocked Photos" feature that works similarly to a hidden album, but with a Google account attached. PIN-It's not synced to the cloud by default, it's only encrypted on the device.
Using the cloud requires careful attention to sync settings. Make sure that Autoupload for hidden albums is turned off if you don't want those photos to be shared with your cloud account, which is especially important when using shared family storage subscriptions.
💡
The combination of methods (Hidden album + Cloud backup with disabled synchronization) gives the maximum guarantee of data safety and confidentiality.
