Losing important text messages on Xiaomi Redmi 9 is a very unpleasant but unfortunately common situation. Accidental touch, software failure or careless system updates can lead to instantaneous disappearance of correspondence containing confirmation codes, addresses or personal information. Owners of Android devices often face panic, believing that data is lost irretrievably, but modern technologies and system features of MIUI provide several effective ways to solve this problem.
The first thing to do when a missing person is to immediately stop using the phone actively. New data can overwrite the memory sectors where deleted messages were stored, making it impossible to recover them even with specialized software. Unlike photos that are often duplicated in the cloud, SMS is stored locally in the system database, and access to them requires specific tools.
In this article, we will take a look at all the current ways to return correspondence, from built-in backup functions to using professional utilities for the PC, learn how to check hidden folders Google Drive and Mi Cloud, and understand when you should resort to root rights for deep scanning of the device memory.
Analysis of Google's built-in backup
The simplest and often ignored method is to check autosaves in a Google account. Android by default offers to back up application data, including messages, provided that this feature has been activated by the user before. On Redmi 9, this process is managed through standard system settings.
To check for backup, go to Settings → Google → Backup. This will show the date of the last saved copy. If the date precedes the moment of deletion of messages, you have a high chance of returning them. It is important to understand that recovery from the Google cloud will replace the current data on the phone with what was at the time of creation of the copy.
The recovery process requires you to reset your settings or initially configure your device if you just bought a phone. When you log in, the system will prompt you to restore data from the last available save point. Read the settings screens carefully so you don't miss the backup selection step.
⚠️ Note: Restoration from Google backup will completely replace the current SMS on the phone with those that were at the time of the backup.
Recovery through Mi Cloud
Xiaomi smartphone owners have access to the company’s own cloud storage, the Mi Cloud, a powerful tool that users often ignore, even though it is capable of synchronizing messages in real time. If your Redmi 9 has a Mi Account enabled and SMS synchronization enabled, your data may be on the manufacturer’s servers.
Check for data not only through your phone, but also through the web version of the service. Go to the official i.mi.com website from a computer or other device, enter your credentials and select the Messages section. If the sync worked correctly, you will see a list of your correspondence.
To return data to the device, perform the following actions:
- 📱 Open your phone settings and go to the "Mi Account" section".
- ☁️ Select "Mi Cloud" and find in the list of "Messages".
- 🔄 Activate the sync switch or press the "Restore" button".
Note that the Mi Cloud has limited free space (usually 5GB), so old backups could be automatically deleted when the storage overflows, and in such cases, it’s worth checking the cart inside the Security app or the cloud itself, if such a feature is available in your version of MIUI.
💡
Check sync status regularly in Mi Cloud to make sure your data is actually stored in the cloud, not just locally.
Using the Mi Mover app for local backups
Many Xiaomi Redmi 9 users use the built-in Mi Mover app to port data, unaware that it also creates local backups. Even if you didn't make a backup specifically before deleting, the system could have created an automatic restore point during the last update or routine check.
Local copies are stored in a hidden file system directory. To find them, open the File Explorer and follow the MIUI → backup → AllBackup path. There may be archives with the.bak extension. If you find a file with a date preceding the loss of data, it can be deployed through the recovery menu.
The process of recovery from a local copy looks like this:
- 📂 Go to Settings. → The phone. → Reservation and rehabilitation.
- 💾 Select the tab "Mobile device" and find the desired date.
- ✅ Check the "Messages" item and start the process.
- 📵 Wait for the operation to end without turning off the smartphone screen.
⚠️ Attention: The recovery process from a local copy can take a long time depending on the amount of data.Do not interrupt the process and make sure that the battery charge is at least 40%.
☑️ Checking local backups
Professional software for data recovery
If built-in methods fail, PC software comes to the rescue. Software like Dr.Fone, Tenorshare UltData, or DroidKit can perform deep memory scans, but the Redmi 9 often requires USB debugging to work effectively.
To activate the developer mode, go to Settings → About Phone and quickly click on the MIUI build number seven times. After that, the “Developers” option will appear in the advanced settings, where you need to activate Debugging over USB.
The effectiveness of third-party software depends on several factors:
- 🔌 Quality. USB-cable and stability of connection to the computer.
- 🔓 The presence or absence of root rights on the device (with superuser rights the chance is higher).
- ⏳ Time since the removal (the less, the better).
Most programs run in demo mode, allowing you to scan the phone and show a preview of the messages found. A full recovery usually requires a license. Successful recovery depends on whether the memory sectors where the SMS was stored were overwritten with new data.
| Programme | I need a Root. | Compatibility with MIUI | Price. |
|---|---|---|---|
| Dr.Fone | Preferably. | Tall. | Paid |
| Tenorshare UltData | No (basic) | Medium | Paid |
| DroidKit | Yes (for deep) | Tall. | Paid |
| SMS Backup & Restore | No. | Complete. | Free of charge. |
Why can't programs see SMS?
Recovery through Communications Operators
There is a myth that mobile operators store the text of all messages for years. In reality, the situation is different: operators (MTS, Beeline, MegaFon, Tele2) store detailed information about the time and number of the sender / recipient (CDR-records, but not the contents SMS. The text of the message is stored on the network only for a short time for delivery.
However, you can request details of calls and text messages (without text) through your personal account or service office. This will not return text, but will help restore the sender's contact information to contact him and ask for duplicate information.
Some operators offer paid services such as Antispam or Cloud SMS Storage, which automatically save copies of messages on the server, and if you have this option, you can restore text through a special service. USSD-operator.
💡
Communication operators do not store the text of your SMS in the public domain for confidentiality reasons, so you should not count on their help in restoring the contents of correspondence.
Preventing Data Loss in the Future
To prevent the loss of important messages from happening again, you need to set up an automatic backup system. On Xiaomi Redmi 9, this can be done with regular funds without installing extra software.
It is recommended to set up automatic backups to Google Drive once a week or daily when connecting to Wi-Fi. It is also useful to periodically make local copies through the Security app and transfer them to your computer or external drive.
Basic data security rules:
- 🛡️ Do not delete messages en masse without prior verification.
- ☁️ Keep an eye on the free space in cloud storage.
- 📲 Install an application for SMS management with archiving function.
Use apps like SMS Backup & Restore that allow you to flexibly adjust your schedule and save copies, giving you complete control over your correspondence history and allowing you to recover data at any time, even when you change your smartphone.
⚠️ Warning: When installing third-party SMS applications, carefully check the permissions you request. Do not give access to messages to unverified programs to avoid theft of sensitive data.
