How to Open Hidden Notes on Xiaomi Redmi 9: From Standard Techniques to Engineering Tricks

Xiaomi Redmi 9 smartphones based on MIUI firmware offer users not only obvious features, but also hidden features - including access to notes that can be hidden in the depths of the system. Did you accidentally delete an important record? Or suspect that someone hid information from your eyes? In this article, we will examine all the legal and safe ways to find hidden notes on your device - from standard tools to little-known techniques.

It’s important to understand that hidden notes on Redmi 9 can be stored in different places, from the Mi Cloud cloud service to system folders that are only accessible through the engineering menu. We won’t look at methods that require root rights or hacking, as this violates warranty conditions and can lead to unstable device operation. Instead, focus on official and semi-official ways that work on current versions of MIUI 12-14.

Before you start searching, make sure you have a backup of important data. Some methods (such as resetting the Notes app settings) can result in unsaved changes being lost, and check if your notes are synced to your Mi Account account, which will make it easier to recover.

1. Search through the standard Notes app

To start with, the obvious is that maybe the notes aren't deleted, they're just hidden inside the app itself. MIUI has a built-in archiving and hiding feature that many users don't know about. Here's how to use it:

Open the Notes app (yellow notebook icon) in the upper right corner, click three dots (⋮) And you can select Archives, which is where you keep all the notes you've ever archived, and if you don't have the right entry, check the Recycle Bin folder, which stores notes for up to 30 days before you delete them.

• 📌 Archive: Notes Hidden by the User Manually.
• 🗑️ Recycle bin: deleted notes (stored for limited time).
• 🔍 Search: Use the search bar at the top to find a keyword note.

If you used the password protection feature for individual notes, they can be found in the main list – they will be marked with an icon. 🔒. You will need to enter for access PIN-a pattern lock or code you have previously installed.

💡

If you forget the password from a protected note, try resetting it through the Notes app settings → Settings → Security → Reset password. This will require confirmation via SMS or email linked to your Mi Account account.

2.Recovery through Mi Cloud

All notes on Xiaomi Redmi 9 are synced by default to the Mi Cloud service if this feature has been activated. Even if you deleted the note on the device, a copy of it could be saved to the cloud.

1. Open your Settings → Xiaomi Account → Mi Cloud.
2. Make sure the switch next to the Notes is on (green).
3. Click on Notes, then select Sync.
4. Open the Notes app and wait for the synchronization to complete.

If you don’t see any notes, try logging into Mi Cloud via your computer’s web browser:

1. Go to i.mi.com and log in.
2. Select the Notes section in the menu.
3. Check the Archives and Recycle Bin folders, there may be hidden or deleted entries.

Important: If the sync has been disabled before the note is deleted, you can't restore it through the cloud, so move on to the following methods.

3. Check hidden folders through the file manager

Some notes (especially those created by third-party applications) can be stored in hidden folders of internal memory, and to find them, you will need a file manager with access to system directories, such as Mi File Manager or Solid Explorer.

Open the file manager and enable the display of hidden files:

1. In Mi File Manager, click on three lines (☰) top-left.
2. Select Settings → Show hidden files.
3. Go to the root directory (/) and open the data folder.

Look for notes in the following locations:

• 📁 /data/data/com.miui.notes — standard annex Notes.
• 📁 /data/com.miui.notes/databases — Notes database (notes.db file).
• 📁 /sdcard/MIUI/Notes — backup copies of notes (if created).

Notes.db can be opened using SQLite database browsing applications, such as DB Browser for SQLite (available on PC), but it is not recommended to edit this file without technical skills, as this can lead to data loss.

Enable the display of hidden files

Check the folder /data/data/com.miui.notes

Find the notes.db file in the databases directory

Copy the file on the PC for analysis (optional)

Do not edit files without a backup copy-->

4.Use of the engineering menu (for experienced users)

If standard methods don't work, you can try to find notes through Xiaomi's engineering menu, which requires caution, because wrong actions can disrupt the system. We'll only look at secure commands.

To access the engineering menu:

1. Open the Phone app.
2. Enter the code ##4636##.
3. Select Phone Information or Testing.

In the engineering menu, go to Storage or Storage, where you can see the complete structure of the device's memory, including hidden system files, but the notes are not directly displayed here - you will need to find a path to the com.miui.notes application database, as described in the previous section.

⚠️ Note: Do not change the settings in the engineering menu unless you are sure of their purpose. For example, resetting the Radio Band parameters may cause a loss of network signal.

The alternative way is to use ADB (Android Debug Bridge for accessing note files, which requires connecting your smartphone to your PC and installing it. ADB-Drivers. A command to copy the database:

adb pull /data/data/com.miui.notes/databases/notes.db C:\NotesBackup\

This command will copy the notes.db file to the C disk: to the NotesBackup folder.

5. Recovery through backup

If you regularly back up your notes through Settings → Additional → Backup and Reset, you have a chance to recover deleted notes. Here's how to do it:

1. Go to Settings → Additional → Backup and Reset → Local Backups.
2. Select the most recent backup (before the date of deletion of notes).
3. Click Restore and select only Notes (so as not to overwrite other data).

If there are no local backups, check backups in Mi Cloud:

1. Open Settings → Xiaomi Account → Mi Cloud → Backup of the device.
2. Select the device and date of the backup.
3. Find the Notes section and click Restore.

Important: Restore from the backup will overwrite current notes. If you add new entries after creating the backup, they will be lost. It is recommended that you first export current notes manually (via Settings → Export in the Notes app).

6. Third-party applications for data recovery

If none of the above methods worked, you can try specialized utilities for data recovery. We recommend only proven programs that do not require root rights:

• 🛠️ DiskDigger scans internal memory for deleted files, including text notes.
• 📱 GT Recovery – Recovers data from apps including Notes and Mi Cloud.
• 🔍 EaseUS MobiSaver – Supports recovery of notes, messages and other text data.

Instructions for using DiskDigger:

1. Install an app from the Play Market.
2. Start the scan (select Basic Scan to find notes).
3. After the scan is completed, filter the results by Text or Documents type.
4. Find the right notes and keep them in a safe place.

⚠️ Note: Most data recovery applications require disabling the Data Protection feature MIUI (Settings → Special facilities → This temporarily reduces the security of the device, so after recovery, turn the protection back on.

Warning: Avoid programs that promise to recover data without a PC connection or request root access.

💡

Third-party applications can only recover notes if their data has not yet been overwritten with new files, and the sooner you start recovering from deletion, the better the chances of success.

7. Appeal in support of Xiaomi

If the notes are critical (e.g., containing legal or financial information) and all independent recovery attempts have failed, you can contact Xiaomi’s official support.

1. Prepare proof: Screenshots of screens with errors (if any), date and time of creation/deletion of the note, Mi Account information (email, linked phone number).
2. Contact us for support: via mi.com/global/support. via the Mi Community app (Feedback section) by phone (hotline numbers for your region can be found on the official website).

In the request, specify:

• 📝 Model of the device (Xiaomi Redmi 9).
• 🔢 IMEI Phone (can be found in the settings) → The phone. → General information).
• 📅 Last synced with Mi Cloud.
• 🔑 Proof of ownership of the account (passport scan may be required).

Important: Xiaomi does not guarantee the recovery of deleted data, but in some cases, support specialists can provide archival copies from the cloud if they are stored on the company’s servers.
