The lock screen on Xiaomi, Redmi and POCO smartphones is often a source of annoyance when it displays unnecessary labels, such as the name of the previous owner, an advertising service provider, a system notification, or even a trail of failed firmware. Unlike other manufacturers, MIUI offers several hidden ways to remove text, from standard settings to technical manipulation of system files.
Complicating the problem is that not all labels are deleted the same way, such as owner text (like "If you find it, return it to the number...") is removed in 30 seconds through settings, and operator ads or system notifications sometimes have to be blocked at the firmware level, and in this article we will examine all current methods, from the simplest to those that require ADB or superuser rights.
1. Delete the label "Device Owner" through the MIUI settings
The most common case is text that the user or previous owner has added to the lock settings, which is displayed under time and usually contains contact information, and can be removed without additional tools:
- Open the Settings β Lock screen.
- Select the Signature on the lock screen (or the Owner's Text in older versions of MIUI).
- Remove the current text and save the changes.
If the item is missing, then the inscription is added in another way (for example, through ADB or third-party applications).
β οΈ Note: Some Xiaomi firmware may leave an empty line after deleting text. MIUI β You can only fix it by resetting the lock screen settings (see Section 4).
2. How to remove the operator's advertising (MTS, Beeline, MegaFon, Tele2)
Telecom operators often embed their logos or advertising messages into the firmware of smartphones. On Xiaomi, this manifests itself in the form of inscriptions like "Thank you for choosing MTS!" or "Connect unlimited Internet." These are harder to remove than the owner's text, but there are working ways:
- π± Shutdown through SIM-menu: Insert SIM-card to another phone, open the operator's app (e.g. "My MTS") and disable the "Advertising on lock screen" option. Return the card to Xiaomi and reboot the device.
- π§ Locking through ADB: Connect your phone to your PC, activate Debugging USB and follow the command: adb shell pm hide com.android.operator.notification Note: Some firmware may have different packet names (e.g. com.mts.mobilereklama).
- π« Delete the system application: If you have root rights, find a folder through Root Explorer /system/priv-app/OperatorApp and remove its contents.
If the camera adverts appeared after the MIUI update, try to roll back to the previous firmware version. Downgrade instructions are in the FAQ.

Before using ADB, check if the OEM Unlock partition is blocked in the developer settings. If so, unlock it, or the commands will not work.
3. Reset the lock screen settings (without data loss)
When the label is not deleted through the menu but explicitly added by the user (for example, after experimenting with themes or launchers), a partial reset will help.This method does not affect personal files, but returns the lock screen settings to factory:
- Go to Settings β About the phone β Reset settings.
- Select Lock screen Reset (or Security Reset in MIUI 12 and later).
- Confirm the action and wait for the reboot.
After reset, all passwords, fingerprints and graphics keys will be deleted if the inscription was added through system files (for example, in the computer system). /data/system/lockscreen_text), This method wonβt help β youβll need a full reset or manual file editing.
| Method | Type of inscription | Required. root/ADB | Loss of data |
|---|---|---|---|
| MIUI settings | Text of the owner | No. | No. |
| Resetting the lock screen | User-generated inscriptions | No. | Passwords/fingerprints only |
| ADB-team | Operator advertising | Yes (ADB) | No. |
| Editing system files | Any inscription | Yeah (root) | Risk of system damage |
4. Manual deletion of inscriptions through system files (for advanced)
If you add a lettering at the firmware level (for example, after an informal patch or custom theme), you can remove it manually.
- π Root rights (or temporary root via Magisk).
- π File Manager with access to system folders (e.g. Root Explorer or Mixplorer).
- π Knowing the ways in which the blocking texts are stored.
The main files responsible for text on the lock screen:
/data/system/lockscreen_text
/system/etc/lockscreen_customization.xml
/vendor/overlay/framework-res__auto_generated_rro.apk (for MIUI 13+)Instructions:
- Open the file manager and follow one of the paths.
- Delete the file with the text or edit it (for example, replace the content with an empty line).
- Reboot the phone.
β οΈ Note: Incorrect editing of files in /system or /vendor This can lead to bootloop. Before you change, backup through the bootloop. TWRP Or OrangeFox.
What if the phone doesnβt turn on after editing files?
5.Use of ADB to remove system labels
ADB (Android Debug Bridge) allows you to manage system settings without root rights, a method that is suitable for removing inscriptions added by the operator or third-party applications.
- π₯οΈ Computer with Platform Tools installed.
- π± Included Debugging by USB on the phone (Settings) β The phone. β Version. MIUI β Press 7 times, then return to the Additional Settings β For developers).
- π Cable USB (preferably original).
Commands for deletion of inscriptions:
adb shell settings delete secure lock_screen_owner_info_enabled
adb shell settings put global lock_screen_show_owner_info 0If the inscription remains, try to find its ID:
adb shell dumpsys activity | grep "mLockScreenText"Then remove through:
adb shell settings delete secure [identifier from output]Install Platform Tools on PC
Enable debugging over USB on your phone
Connect your phone to the original cable
Check the connection with the adb device command
Backup important data-->
6. Full reset settings (last resort)
If no methods have worked, then hard reset, which is a complete factory reset, will delete all data, including photos, messages and apps, but is guaranteed to clear the lock screen of any labels.
How to reset:
- Go to Settings β About the phone β Reset settings.
- Choose Delete all data (or Factory Reset).
- Confirm the action and wait for the completion (it will take 5-10 minutes).
Important: If the message is due to a virus or malware, check it for threats before recovering data from the backup (for example, through Malwarebytes).
β οΈ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3 Pro) after reset, you may need to re-assign your Mi Account. If you forget your password, restore it in advance at account.xiaomi.com.

A complete reset is the only way to remove the firmware-level inscriptions (for example, after a failed update or hack).
