Owners of smartphones Xiaomi, Redmi and POCO Often use the built-in Notes feature to store important information, passwords or personal records, but when it comes time to find this data, users face difficulties, especially if security has been installed previously or notes have been moved to a hidden partition. Security system MIUI HyperOS hides sensitive content from prying eyes, which is a plus for privacy, but creates difficulties when trying to access it.
There are several ways to get into this closed section, and the choice of the specific method depends on whether you remember the previously set password or pattern lock. If you just forgot where the icon is, or can not remember the unlock combination, do not panic. Modern shells from the Chinese manufacturer provide recovery mechanisms through the Mi Account, but there are also nuances that you need to know in advance.
In this article, we will go through all possible scenarios, from the trivial search of a hidden folder to the complex procedures of resetting a forgotten password. We will look at the system constraints, the features of synchronization and how the application behaves when changing devices. Understanding these processes will help you not only regain access to your records, but also protect them in the future from unauthorized access.
Where to find hidden notes in the app
The first thing to do is locate the standard Notes app, which is pre-installed on all smartphones of the brand. the interface of the program may vary slightly depending on the version of the shell (MIUI 12, 13, 14 or new HyperOS), but the logic of the work remains the same: Hidden notes are not displayed in the general list immediately after opening the application; they are in a separate secure section, the entry to which requires a certain action.
To access a hidden album, you need to pull down on the note list home screen until you see a characteristic animation or lock icon. Some firmware versions require you to click three dots in the upper right corner and select Hidden Notes. This is where all files marked as confidential are stored, and if you see a password request, then the security is activated correctly.
It's important to understand the difference between just deleted notes and hidden ones: deleted files go into the bin and are stored there for 30 days, then disappear forever, and hidden notes do not disappear from the device's memory, they are only visually isolated from the general viewing. Access to them often requires proof of identity, which can be done through a pattern lock, digital. PIN-a code or fingerprint if the biometrics have been configured previously.
⚠️ Note: If you are trying to log into hidden notes from a new device, the list will be empty until you sync with the Mi Cloud. Local hidden files are not automatically transferred without your permission.
Users often confuse hidden notes with secure folders in the file manager. These are different functions of the system. Notes are stored in the application database, rather than as separate text files in an open directory, which provides an additional layer of encryption. So searching through the explorer for keywords from the content of the note will be useless without first unlocking the application itself.
Login methods for forgotten password
The situation when a user forgets the password from hidden notes is one of the most common. Fortunately, Xiaomi developers have provided a mechanism for restoring access, but it works only under one condition: if you previously had a Mi Account attached. Without an account, it is almost impossible to reset protection for security reasons, since this would allow attackers to easily access personal information.
If you type in the wrong password, you'll see a "Forgot your password" button or similar request several times on the screen, and if you click on it, the system will prompt you to log in to your Mi Account, and after successful verification, you'll be asked to install a new access code or graphical key, which takes no more than a minute if you have a stable Internet connection.
If the account is not linked, the options are narrowed dramatically, and in this case, you can try to remember whether the default Mi Account password or the screen unlock pattern was used to protect the default Mi Account, and the system sometimes suggests using them as an alternative. However, if neither option fits, the data may be lost forever, as workarounds through the engineering menu or the slate are not available. ADB-There is no command for this particular security function.
⚠️ Warning: Attempting to use brute-force will temporarily block the input function, after several failed attempts, the system will block the input for 30 seconds, then for 1 minute and then on the increasing function.
There is a myth that resetting your phone to factory settings helps remove protection from your notes. This is a dangerous misconception: Resetting will remove all data from your device, including hidden notes themselves, if they were not synced to the cloud. So before any drastic action, make sure that important information is stored in Mi Cloud or on another medium.
Set up biometrics and Mi-account
For maximum convenience and security, it is recommended to configure the entrance to hidden notes using biometric data, which eliminates the need to enter a complex password every time, supports facial recognition (Face ID) and fingerprint scanning, activation of this function is done directly in the settings of the application “Notes” or in the general privacy settings of the system.
To add biometrics, go to the hidden notes menu, click on the settings icon (usually a gear or three dots), and select Add a fingerprint or Face Recognition. The system will ask you to confirm the action with a password from the Mi Account. After that, when you try to open a hidden album, the smartphone will request a finger or a face scan, which greatly speeds up the access process.
☑️ Set up note protection
The role of the Mi Account in this ecosystem is critical, and it serves as a security anchor, and if you lose access to your account, you lose access to all the hidden data, so we strongly recommend that you include two-factor authentication for the account itself and remember the recovery email or phone number, which ensures that even when you change your smartphone, you can easily regain access to your records.
It’s also worth noting that different devices with the same account may not automatically sync their security settings in terms of biometrics, so you’ll have to re-introduce your fingerprint on your new phone, even if it’s already been set up for notes on the old one, to protect the biometric patterns that are stored locally in each device’s secure security module (TEE).
Synchronization and cloud storage
One of the key features of Xiaomi's ecosystem is cloud synchronization, which works slightly differently for hidden notes than for regular ones. By default, the content of hidden notes may not be uploaded to the cloud to save space and increase privacy. You need to manually activate synchronization for this type of data in the Mi Cloud settings.
The advantage of cloud-based storage of hidden notes is that you can access them from any device, whether it's a tablet, another smartphone or a web version of the cloud, but to see them on a new device, you need not just log in to your account, but you also explicitly allow hidden data to be downloaded. When you first log in, the system can request confirmation via SMS or an additional security code.
| Parameter | Local storage | Synchronization of Mi Cloud |
|---|---|---|
| Access without network | Complete. | Only cached |
| Resetting protection | Data is deleted | Data is retained |
| Access to PC | Impossible. | Through i.mi.com |
| Occupied seat | Phone memory | Cloud storage |
It's important to consider the limits of free space in the cloud. Free rates usually provide 5GB, which are shared between photos, system backups and notes. If you store a lot of hidden notes with attachments (photos, audio), the place may run out and sync will stop, in which case new hidden notes will only remain on the device until you free up space or buy a subscription.
What happens when the internet is shut down?
Addressing access problems
Often, users are faced with a situation where the Notes app does not work correctly: a hidden partition does not open, an authorization error crashes or a list is empty, although the notes should definitely be there. Most often the problem lies in desynchronizing time and date on the device or in an outdated version of the application.
Another common cause is an app cache failure. In this case, cleaning the program data helps. Go to Settings → Apps → All Apps → Notes, select Clear and then Clear All Data. Fear not, this won't delete your notes if they're synced with your account, but will reset display settings and temporary files, which often solves the hang-up problem.
💡
If you have lost hidden notes after the system update, check to see if the application has changed its request for special permissions. Newer versions of Android and MIUI sometimes require you to reconfirm access to the storage.
In some cases, the problem may be with third-party launchers or themes that conflict with system security features. Try switching to the standard theme and standard launcher to see if the hidden partition will be accessed, and it’s also worth checking if the Guest mode or the second space is enabled, since they have no access to the main profile notes.
⚠️ Note: When using two spaces, the notes from the main profile are not visible in the second space and vice versa.
Transferring data to a new smartphone
When buying a new Xiaomi smartphone or switching from a different brand device, it is important to correctly transfer hidden notes. Simply copying files via Bluetooth or Mi Mover is often not enough, as protected content requires additional authorization. The best way is to restore from a Mi Cloud backup when you initially set up a new device.
If you are using a local backup, make sure that the backup settings select the option “Including system data” and specifically marked “Notes”. When you restore from such a backup on a new device, you will need to enter the password from the Mi Account that was used on the old phone to decrypt the protected partition.
💡
The most reliable way to transfer hidden notes is to sync completely through the Mi Cloud before changing your device, not locally.
If an old phone is already sold or broken and the sync has not been turned on, it is impossible to recover hidden notes, which is a fundamental principle of data encryption on modern smartphones: without a key (password) and without a media (files on the device or in the cloud), information is not available, which is why regular checking of sync status is a critical habit for every user.
For those who move from iPhone to Xiaomi, the process of transferring notes can be difficult, as storage formats differ.Mi Mover can transfer the text of ordinary notes, but hidden iOS notes often do not migrate to the secure partition of the Android smartphone automatically, in such cases, it is recommended to pre-open hidden notes on the iPhone, copy their text and create new ones already on the Android device.
