How to find and open a hidden note on Xiaomi Redmi Note 9: the complete guide

Xiaomi Redmi Note 9 is one of the most popular mid-range smartphones, but even its owners are not always aware of all the hidden features of MIUI firmware, among them the hidden note feature, which allows you to store confidential information in a secure partition. However, access to this data is not always obvious: the system can hide it behind several layers of protection or non-standard gestures.

If you have forgotten where your hidden notes are stored, or can't find them after you update your firmware, this article will help. We'll look at all the possible ways to access them, from standard methods through the Notes app to technical techniques using file manager and ADB. It's important to understand that some methods require super-user rights (root), and others only work on certain versions of MIUI. Ready to figure it out?

1. Standard method: Notes app and protected section

The easiest way is to use the built-in Notes app (or Notes in international firmware), which Xiaomi has integrated into the hidden note feature, but not all users know how to use it.

• 📱 Open the Notes app on the home screen or in the app menu.
• 🔒 In the upper right corner, tap the icon "Three dots» (⋮) → Select Protected Notes.
• 🔐 The system will request a password, fingerprint or pattern lock (depending on the screen lock settings).
• 📝 Once authenticated, you'll see a list of all the hidden notes.

If the Protected Notes section is not on the menu, it may mean:

• ❌ You have custom firmware installed without support for this feature.
• ❌ The Notes app has been updated via Google Play and the Hidden Notes feature is disabled.
• ❌ You have never created hidden notes (check the regular section).

⚠️ Warning: If you reset your smartphone to factory settings, hidden notes will be deleted without recovery!

Make sure you use the standard Notes app (not third-party)

Check the MIUI version (settings → About the phone)

Remember if you set a password for secure notes.

2. Alternative access via "Private Safe"

Since MIUI 12, Xiaomi has implemented Private Safe, a protected partition for files, photos and notes, and hidden notes can be stored there to check:

1. Open the File Manager application.
2. Go to the Personal Storage section (may be called Private Safe or Safe).
3. Enter a password or use biometrics to unlock.
4. Check Notes or Notes folder – exported hidden files may be stored there.

If the folder is not available, try creating a test hidden note through the Notes app and see if it shows up in Personal Storage to see if data is synchronized between services.

On the Redmi Note. 9 s MIUI 12.5 Hidden notes can be duplicated in the Private Safe folder under the name encrypted_notes.db — This file cannot be opened without root rights.

3.Technical method: manual search of note files

If the standard methods didn't work, you can try to find the notes manually through the file manager with access to the system folders.

1. Install a file manager with root support (such as Solid Explorer or FX File Explorer).
2. Go to /data/data/com.miui.notes/files/notes/ Or for international firmware: /data/data/com.miui.notes.global/files/notes/
3. Look for files with the.db or.json extensions, which may contain hidden notes.
4. Copy files to your computer and try opening them with SQLite Browser or a text editor.

⚠️ Note: Without root rights, you will not be able to access the folder /data/data/. Attempts to change permissions manually can cause app Notes to crash!

If you have root access, you can use ADB to extract files:

adb pull /data/data/com.miui.notes/files/notes/ ~/Downloads/notes_backup

Decrypting the database requires specialized tools like miui-notes-decrypt (available on GitHub), which requires technical skills and can violate warranty.
