Users of Xiaomi and Redmi smartphones often face a situation where important entries, shopping lists or work ideas disappear from the main list without a trace, this can happen after a random swipe, system update or when changing an account.
Before you look for complex solutions, you need to understand the logic of how the MIUI and HyperOS shells work. Hidden items can be in an archive, in a restricted folder, or synced with cloud storage under a different profile. The phone's local storage doesn't always display all files unless the correct filtering is configured.
In this article, we will discuss all possible scenarios for information loss and how to return them, learn how to access password-protected files and where to look for data if the application has been deleted or damaged.
Search in archives and standard folders
The most common reason for "lost" records is their accidental archiving, the user can accidentally click on the corresponding icon, after which the item disappears from the general list, but is not permanently deleted. To check this option, open the application and carefully examine the top of the screen or side menu.
In newer versions of HyperOS, the interface may be different from the classic MIUI 12 or 13. The archive access button is usually located as a box icon or a folder with an arrow, and clicking on it will take you to the section where all the deposited materials are stored.
- 📂 Click on the menu icon (three dots or stripes) in the top corner of the screen.
- 📂 Select Archive or Recycle Bin if the entry has been recently deleted.
- 📂 Check the Favorites folder if you have labeled a star on important files.
If you find the file you want in the archive, you can easily return it to the general list, and you just need to select the record with a long press and select the option "Restore" or "Remove from archive" and the data will instantly return to the main screen of the application.
💡
Check the Recycle Bin folder regularly in the application settings, as files are only stored there for 30 days, after which they are deleted permanently without the possibility of recovery.
Access to hidden notes through the protection function
Xiaomi and Redmi Note devices have a built-in Hidden Notes feature that requires additional authorization to view, not just an archive, but a secure partition that can only be accessed after you enter a special password or a pattern lock.
To open this section, you have to do the actions in the list interface, and often users just don't know that there's a hidden gesture, so you have to go to the master directory of all the records and pull the list down until the lock animation or the input field appears.
The system will ask you to enter a privacy password, which could be the same code that is used to protect apps or hidden albums in the gallery, and if you forget this code, it will be extremely difficult to restore access without a linked Mi Account.
⚠️ Note: After several failed password attempts, the system may temporarily block the login option or require confirmation through a Google or Xiaomi account.
It is important to understand the difference between a regular archive and a hidden storage, the archive is visible immediately, and special actions are required to access the second one, and the encryption of the data in this section ensures a high level of security of personal information.
☑️ Checking access to hidden data
Recovery through Mi Cloud and Synchronization
If you can't find the data on the device, the next search point is cloud storage, Mi Cloud automatically saves copies of your records if you have the appropriate sync option enabled, which often saves the situation when you lose your phone or reset your settings.
To check, log in to the official cloud service website via a browser on your computer or other smartphone. Use the same account that was active on your Redmi Note. In the web version interface, select the Notes section.
You can often find versions of files that have been deleted locally but have not yet been cleared from the cloud. The web version interface allows you not only to view, but also edit text, as well as export it to other formats.
| Parameter | Local storage | Mi Cloud | Google Keep (alternative) |
|---|---|---|---|
| Access without the Internet | There is. | No (download needed) | Depends on the settings. |
| Risk of loss on discharge | High-pitched | Absent. | Absent. |
| Encryption | Basic | High. | Standard. |
| Limit of volume | Depends on the phone's memory. | 5GB free of charge | 15 GB (total) |
Make sure your device is automatically synced. Go to Settings → Mi Account → Mi Cloud and check the slider opposite Notes. If it is turned off, no new records will be saved to the cloud.
Use of Third-Party File Managers
Standard notes in Xiaomi are stored as a database, not as separate text files that can be opened. However, if you used the attachment format (pictures, audio), they may lie in hidden system folders, and you will need root rights or special file managers to find them.
One way to find traces of deleted or hidden files is to use the MT Manager app or standard Explorer with hidden files enabled, and the path to data often runs through the /data/data/com.miui.notes/ directory, but is not accessible to ordinary users.
If you don't have superuser rights, look for backups. Some users backup through Mi Mover or third-party utilities. In those archives, you can find files with the.bak or.xml extension containing the text of your records.
Be careful when working with system files. Incorrectly changing the structure of folders can lead to malfunction of the entire application of notes or the system as a whole. Always back up before interfering.

Problems after updating MIUI or HyperOS
Often, users experience the disappearance of notes immediately after an operating system update, because a new version of an application may have a changed database structure or file path, in which case the data is not deleted, but simply “lost” for the new interface.
The first thing to do is to check the version of the app in the GetApps store or Google Play. Perhaps the Notes system component requires a separate update that did not automatically occur along with the firmware.
It is also worth clearing the app cache. Go to Settings → Apps → All Apps → Notes → Memory and click the Clear Cache button. It is important not to confuse this button with Clear All, as the second option will delete all your records.
- 🔄 Make sure that the date and time on the device are set automatically.
- 🔄 Try to log out of your Mi Account and log in again to restart sync.
- 🔄 If nothing helps, install an earlier version of the app (APK) proven.
⚠️ Note: When installing older versions of applications (rollback version), the system may require you to delete the current version along with the data!
