Xiaomi smartphone owners often use file hiding to protect their personal information from prying eyes. However, sometimes there is a situation when access to their own data is lost, or the user simply forgets where exactly the important text has moved. The standard MIUI or HyperOS interface does not always offer obvious ways to return to hidden content, which causes panic among inexperienced users.
Hidden notes are not just deleted files, they are moved to a special secure part of the system, access to which is limited by password or biometrics. Understanding the architecture of the hidden folder in the Xiaomi shell is the key to successful access recovery. In this article, we will discuss in detail all possible ways to log into this partition using the standard system tools.
Don't worry if you forget the exact algorithm, Xiaomi's security system is designed to keep the data available to the owner with the right credentials, and we'll look at both the software login methods and the password-loss actions, based on the latest firmware versions.
The principle of operation of hidden folders in MIUI and HyperOS
Xiaomi’s hidden file mechanism is based on creating a virtual storage device that doesn’t appear in a standard file manager without authorization. When you hide a note or file, the system doesn’t delete it, it transfers it to an encrypted container.
It is important to understand that hidden items may be associated with a Mi Account, which means that the data is synced to the cloud, but in encrypted form. If you have changed your phone but use the same account, access to hidden notes may require additional verification. Hidden notes are not displayed in the Mi Cloud in plain view, they are only available after unlocking on the device.
There are several layers of protection that can be activated by the user, which can be a pattern lock, a digital key. PIN-code, password or biometric data (fingerprint, Face) ID). The system allows you to combine these methods, but the primary login to a hidden folder often requires the basic security password.
⚠️ Warning: Resetting the lock screen password via Recovery Mode will result in a complete cleanup of phone data, including hidden notes, if they were not synced with Mi Account in advance.
Users should distinguish between hidden albums in the gallery and hidden notes in the Notes app. While the security mechanisms are similar, access paths may differ. Newer versions of the HyperOS shell have unified these features, but older Android 10-12 models may have their own navigational features.
Search for hidden notes through the Gallery app
One of the most common ways to access hidden content on Xiaomi is by using hidden gestures in the Gallery app. Many users are unaware that the standard gallery has a built-in concealment mechanism that is swiped activated.This method works on most devices, even if the Notes app does not display the hidden partition directly.
To enter, you need to open the gallery and go to the Album tab, and you need to find any album (for example, "Camera" or "Screenshots") and pull the list of albums down. If the concealment function is activated, a field will appear to enter your password or fingerprint. Once you successfully log in, a section will open with hidden photos and, in some versions of the firmware, attached notes.
- 📱 Open the Gallery app on the main screen.
- 👇 Go to the Albums tab at the bottom of the screen.
- 🖐️ Make a swipe from the bottom up in the center of the screen (or pull down, depending on the version). MIUI).
- 🔐 Enter a previously set security password or use biometrics.
If nothing happens after swiping, the album hiding feature may be disabled in the settings. Check the gallery settings, look for Hidden Albums and make sure the switch is active. It's also worth checking if the security password has been changed recently, in which case the system can request a new code.
💡
If the swipe doesn’t work, try pinching your finger on an empty spot in the album for a few seconds — in some versions of MIUI, it’s an alternative way to call up the hidden file menu.
Access through file manager and conductor
The MIUI file explorer (or "Files" in HyperOS) also has access to hidden storage, which is especially relevant if you've hidden notes as files or exported them. Unlike in the gallery, it's managed through the app's settings menu.
To get into the hidden section, open the explorer and go to the Documents or Images category. In the upper right corner of the screen is a menu represented by three dots or a folder icon. When you click on it, you will see the "Show Hidden Files" option, activating this mode will require verification of identity.
It is important to note that in the file manager, hidden notes can appear as files with the.note extension or be located in a special system folder whose name begins with a dot (for example,.hidden_notes). To view such folders, it is necessary to enable the display of hidden system files in the conductor settings.
| Access method | Necessary rights | Risk of data loss | Difficulty |
|---|---|---|---|
| Gallery (swipe) | Password/Biometry | Low. | Low. |
| File manager | Security password | Medium. | Medium |
| Annex Notes | Password of the note | Low. | Low. |
| Reset via Mi Account | Access to the account | High-pitched | Tall. |
Using third-party file managers, such as Total Commander or ES Explorer, without root rights will not allow you to see the contents of the hidden folder Xiaomi.
Use of the Application Notes for Recovery
The most direct way to find lost texts is to work with the native Notes app. In recent versions of the shell, the interface has been updated, and hidden notes are now often placed in a separate category within the app itself, rather than hiding in the general settings of the phone.
Open the app and look at the top of the category list, and you can have a folder called Hidden Notes or a lock icon, and when you click on it, the system will ask for a password, and if you forgot the password from the notes, but remember the password from the Mi Account, the system can offer a reset over the Internet.
☑️ Checking the settings of Notes
In some cases, the notes don't disappear, but simply hide their preview. Go to the app settings (three dots in the corner -> Settings) and check the "Security" or "Privacy" section. Make sure that the hid notes feature is enabled. If it is turned off, previously hidden files can become visible in the general list or, conversely, stop showing before the function is turned on.
⚠️ Note: When you delete the Notes app or clear its data through your Android settings, all local hidden notes will be irretrievably lost if you didn’t enable synchronization.
Resetting password through Mi Account
If you remember your Xiaomi account but you forgot the password from the hidden folder, it's the safest way to recover, and it allows you to reset the security password associated with the device via a web interface or re-authorization, but this method only works if the phone has access to the Internet.
To start, go to your phone's settings and find the Passwords and Security section, select Privacy or Privacy Protection. If the system requests an old password that you don't remember, click on the "Forgot your password?" link, and you will be redirected to the Mi Account login page.
Once you successfully enter your username and password from your account, the system will suggest you set a new security password for your device, and after that, the old password from the hidden notes will no longer work, and you will need to use a new one. Importantly, this will not restore the old notes automatically if they were encrypted with the old key, but will open up access to the control of the hidden function again.
What if your Mi Account is forgotten?
Access problems after system update
Often users are faced with a situation where, after updating MIUI or switching to HyperOS, hidden notes cease to appear or request an incorrect password.This is due to a change in encryption algorithms in new versions of Android.
First of all, make sure the update is correct. Go to Settings → About Phone → MIUI Version and check the status of the updates. If the system suggests installing a security patch, do it. Sometimes the bug with access to hidden files is fixed by the hotfixes.
If the problem persists, try clearing the Security app cache (without deleting data). path: Settings → Apps → All apps → Security → Memory → Clear cache. This action is safe for your data, but can restart encryption services.
- 🔄 Check for system updates in the About Phone section.
- 🧹 Clear the cache of the system application Security.
- 🔑 Enter the password that was used before the update.
- ☁️ Check the synchronization status in the Notes app.
💡
After a major firmware update (for example, from Android 13 to 14), the encryption algorithms may change, which will require re-authorization in protected partitions.
