Where to store remote SMS in your Xiaomi phone: the complete guide

Users of Xiaomi, Redmi and Poco smartphones often face situations where important messages suddenly disappear from the dialogue list, whether due to accidental touch, a failure in the MIUI system, or after cleaning the cache, at which point the question arises: where exactly does this data go and can it be returned?

Unlike a computer operating system, the Android file structure doesn't allow you to just go into a folder and find a text file with all the correspondence. The messaging database is a complex system file that is restricted to superuser rights. Understanding how the operating system marks the place to write new data is key to successful recovery.

There is a common misconception that deleted information is immediately erased from the physical memory medium, in fact, the system only marks the memory cells as free to write, and the data bits themselves remain in place until new information is written on top of them, and this is the time interval that gives a chance to save lost dialogues if you act quickly and competently.

System Message Storage in Android and MIUI

Technically, all incoming and outgoing SMS messages are stored in a special SQLite database. In the Android operating system, which runs the MIUI shell, this file has the standard name mmsms.db. It is located on the system path /data/data/com.android.providers.telephony/databases/. This is where your texts, sender numbers and time stamps are physically located.

The problem is that the /data/ partition in Android is closed by default to the average user, and this is done for security reasons so that malware or inexperienced users can not damage critical system files. Without the presence of Root rights (superuser rights), you can not directly access this file through a standard file manager.

When you delete a message in the Messages app, the system doesn't delete a string from the database instantly, it marks it as deleted, and the space it occupied becomes available for a new record. Until new data is written to this memory sector (photos, applications or new SMS), the original information is theoretically readable by special utilities.

💡

Xiaomi owners with Mi Cloud sync enabled should check the cloud first, which is the easiest way to get lost in panic.

It is worth noting that newer versions of MIUI and HyperOS have increasingly advanced data encryption mechanisms, meaning that even with Root access, reading the database can be difficult if the device has been locked or restarted after deleting messages.

Local backups and their location

The most reliable way, provided by the developers themselves Xiaomi, is to use the built-in backup function. If you previously activated the creation of local copies, your messages could be saved as a separate file archive. You can find this data by going along the way: Internal drive → MIUI → backup → AllBackup → SMS.

Backup files usually have the.bak extension or are encrypted archives tied to your Mi Account. To view them, you will need to use the standard recovery application, which is located in the phone's settings menu. → The phone. → Reservation and rehabilitation.

It's important to consider how often you make copies of them, and by default, the system may not automatically create them unless you set the schedule, so if the last copy was made a month ago, you can't recover the last deleted message from yesterday.

There is also the option of backing up your computer using Mi PC Suite or third-party utilities like Mi Backup, in which case files will be stored on your PC’s hard drive, which greatly improves the chances of data being saved in the event of a breakage of the smartphone itself.

Cloud Storage: Mi Cloud and Google Drive

Xiaomi’s ecosystem offers integrated cloud storage, Mi Cloud. If you have SMS sync activated in your settings, copies of your messages are stored on the company’s servers. To check for them, you need to go to the Mi Account settings on the device itself or through the i.mi.com web interface.

An alternative and often more reliable storage is a Google account. The Google Messages app, which is often set by default or downloaded by the user, can automatically save your correspondence history to Google Drive. You can check for a copy by opening the Google Drive app, clicking on the menu and selecting “Backups”.

Recovery from the cloud requires full authorization under the same account from which the reservation was made, and when you reset your phone to factory settings or when you initially set up a new Xiaomi device, the system will itself suggest recovering data from the cloud if it detects the appropriate backup.

Keep in mind the importance of a stable Wi-Fi connection to download large amounts of data from the cloud, and mobile internet can be unstable, resulting in a recovery error or interruption of the process.

Using third-party software for recovery

When built-in tools fail, specialized data recovery software comes to the rescue, with Dr.Fone, Tenorshare UltData, and DiskDigger being the most popular solutions on the market, scanning the device’s memory to find the tails of deleted files.

For most of these programs to work effectively on Xiaomi smartphone, you need to activate the debugging mode over USB. This is done in the hidden menu “For developers”, which is called by seven times pressing the build number in the “About phone” section. After activation in the Settings menu → Advanced Settings → For developers, you need to switch the slider “Debugging by USB”.

Programs are very dependent on having Root rights. Without superuser rights, the program can scan only the available memory areas, which reduces the chances of success to a minimum. With Root rights, deep scanning allows you to find data that you can't see with conventional methods.

Be careful when choosing software: many “free” programs only scan the device, but require payment for the recovery process itself, and downloading dubious software from unverified sites can lead to infection of the phone with viruses.

Analysis of hidden folders and app cache

Some instant messengers and SMS apps can create their own logs or cache files where text is temporarily stored. For example, Google Messages can save thumbnails or temporary files in the /Android/data/com.google.android.apps.messaging/ folder.

Also worth looking at is the /data/local/tmp/ folder, where some system processes can dump temporary data. However, access to it, as with a database, is closed without Root rights. Attempting to circumvent these limitations through system vulnerabilities can lead to unstable phone operation.

There is a "Second Space" or "Guest Mode" feature in the MIUI shell, and if you use these features, it's worth checking if messages were accidentally saved or deleted in another user profile, and switching between profiles is done through settings or notification curtains.

💡

The fewer actions you take on your phone after deleting your SMS, the more likely they are to be recovered, as new data won’t overwrite old memory sectors.

Logcat analysis is a method for advanced users: logs may contain messages that arrive, but text is rarely stored in fragments, and logs require ADB (Android Debug Bridge) knowledge.

Table: Comparison of methods for searching for remote SMS

To help you understand the different ways you can search and recover data, we have developed a comparison table that will help you evaluate the effectiveness of each method and choose the most suitable one for your situation.

As you can see from the table, having a pre-built backup is the easiest and most reliable way, and using sophisticated methods with Root rights is only justified in cases of extreme necessity and lack of other options.

The effectiveness of the methods can vary depending on your Xiaomi model and the version of the firmware installed. On older devices with Android 9 and lower, the chances of recovering without backups are higher than on newer models with Android 13-14.

Precautions and important warnings

When trying to recover data, it is important to be careful, and the main danger is that active actions to install programs or scan the phone can lead to overwriting the very sectors of memory where remote SMS are stored.

⚠️ Warning: Do not install recovery software directly on the phone's internal drive if you want to save data. SD-card or connect your phone to your computer by running a scan from your PC.

Another critical point is getting Root rights. Unlocking the bootloader and getting superuser rights on Xiaomi devices often results in a complete data reset (Wipe Data) for security purposes. If you do this after deleting the SMS, the hope of their return will disappear completely.

⚠️ Note: The Xiaomi bootloader unlock procedure automatically erases all data from the device. Do not start this process if your goal is to restore deleted files rather than reflash the phone.

Also beware of phishing sites that offer “magic buttons” to recover SMS online. No site has access to your physical device’s memory without installing special software or having a cloud copy, and sharing personal data with such resources can lead to account theft.

Regular backups are the only guarantee of data security: set up automatic backups in Mi Cloud or Google Drive so that you do not face the problem of finding deleted data in the future.
