Modern Xiaomi, Redmi and POCO smartphones offer users a wide range of personalization options, and one of the most useful features is the ability to leave a note or contact information directly on a locked display, which helps in situations where the phone is lost and the finder can contact the owner without having to unlock the device.
In this article, we will discuss in detail how to write text on the lock screen using built-in Android system tools and MIUI or HyperOS shells. You will learn where to find the right switches, how to avoid typical errors and what restrictions the manufacturer imposes on the length of the message.
The device owner or device information function is autonomous and does not require third-party applications. The text signature will be displayed under the clock or date, attracting attention. Let's get to the practical implementation.
Where to find the information display settings
The first thing you need to do is get into the right settings menu. The interface of MIUI and the new HyperOS may be slightly different, but the logic remains the same. You need to open the Settings app and find the partition that controls the look of the lock screen.
In most current firmware versions, the path is as follows: Settings → Lock screen. In some cases, especially on older versions of Android, this item may be hidden inside the Settings menu → Screen and brightness → Lock screen.
This is where all the options associated with the watch, widgets and owner signature are located. Please note that on global firmware versions, item names can be translated as "Info about device" or "Owner info".
- 📱 Open "Settings" on the main screen.
- 🔍 Find the "Block screen" section (or "Always-on display").
- ⚙️ Look for "Device Information" or "Owner".
- 📝 Enter the desired text in the field that appears.
⚠️ Note: On some models with a heavily modified interface (for example, Chinese versions of firmware without Russian), this item may be called "Lock screen signature".
Why don't I see this item?
Setup of the device owner's signature
Once you go to the menu, you'll see a text input box, which is where you can write a message that anyone who picks up a phone will see, and it allows you to use letters, numbers and some special characters.
Enter the information that will be most useful in the event of a loss, it can be an alternative phone number, an email address or a phrase like "If found, please call the number..." The message is limited in length, usually up to 30-50 characters, so state the idea briefly.
Some versions of the shell allow you to choose the font or color of text if you activate Always-on Display mode (always on screen). However, the standard lock screen when the display is gone is most often displayed in white or black depending on the selected wallpaper.
☑️ Pre-conservation checks
Use of the "Always on screen" mode
The function deserves special attention. AOD (Always-On Display: If your Xiaomi smartphone supports this technology (usually the models with the same technology) AMOLED-The owner’s text can be displayed even when the phone is lying up and locked.
To activate, go to Settings → Lock screen → Always-on display. Here you can select the style of display of the watch and add a caption. Unlike a regular lock screen, here the text can be more noticeable due to the contrast with the black background of the matrix.
It is important to consider that the constant operation of the screen increases battery consumption. It is recommended to adjust the AOD schedule, for example, turning on only from 8:00 to 23:00, or activating the phone by lifting.
- ⏱ Set up a work schedule for Always-on Display.
- 🎨 Choose a style that supports text.
- 🔋 Watch the battery level.
- 👆 Check the proximity sensor (the screen should go out in your pocket).
💡
To save battery power, use the "On 10 seconds after touch" mode instead of the screen's constant glow.
Third-party customization applications
If the standard means MIUI You don't have enough, Google Play offers a lot of solutions, and apps like Lock Screen Message or Notifies allow you to display complex widgets on the lock screen, QR-contact codes or flashing notifications.
These programs require special permissions to display over other windows and access the notification system, which is necessary to ensure that the message overlaps the standard clock and remains visible.
However, using third-party software has its own risks: they can consume more power than the system counterpart, and sometimes conflict with unlock gestures, and advertising in free versions can annoy the user.
| Method | Difficulty | Battery consumption | Flexibility of setting |
|---|---|---|---|
| System setup | Low. | Minimum | Only text |
| Always-On Display | Low. | Medium. | Text + Graphics |
| Third-party annexes | Medium | High-pitched | Maximum |
Mode of the lost device through Google
There's another way to write text on a screen that's remotely activated, and if your phone is lost, you can use Google Find My Device, and by logging into your account with your smartphone, you can select "Block the Device."
In this mode, your message and the number button will appear on the lock screen, which works even if the phone is in sleep mode, and you can not interrupt such a message using normal settings.
This is ideal for emergency situations when you need to urgently contact the finder.The text will hang until you unblock through your Google account or enter the correct one. PIN-code.
⚠️ Note: To work this method, the phone must be on and have an Internet connection (mobile or Wi-Fi). Without a network, the command to lock with text will not reach the device.
Frequent problems and their solution
Users often experience a situation where the typed text is not displayed. One common reason is an active theme. Third-party themes from MIUI Themes store may have their own lock screens that ignore the system signature settings.
Text may also not appear if Do Not Disturb mode is enabled with certain content concealment settings, although this affects notifications rather than static signatures.
If you have updated your firmware and the feature is gone, try clearing the Settings app cache or resetting the lock screen settings. Sometimes a simple smartphone restart helps.
- 🔄 Switch to the standard theme of design.
- 🧹 Clear the cache of system applications.
- 📱 Restart the device after making changes.
- 🔍 Check for system updates.
