To add custom text on the lock screen in LineageOS using ADB, you typically need to modify system files or use a custom lock screen app, as LineageOS does not natively support adding arbitrary text via ADB commands. Here’s what you can do:

1. Using a Custom Lock Screen App

• Install a third-party lock screen app from F-Droid or the Play Store that supports custom text. Some apps allow you to add widgets or text overlays on the lock screen. You can then use ADB to install and configure these apps if needed.

2. Modifying System Files (Advanced)

• If you have root access, you can edit system files to add text. For example, you might modify the lock screen layout XML files in /system/priv-app/SystemUI/ or /system/app/. However, this requires root and is not recommended for most users due to the risk of breaking system stability.

3. Using ADB to Push Custom Text (Limited)

• ADB itself does not provide a direct command to add text to the lock screen. However, you can use ADB to push a custom lock screen app or modify system settings if you have the necessary permissions and technical knowledge.

4. LineageOS Built-in Options

• LineageOS allows some lock screen customization (like clock and owner info) via Settings > Security > Gear icon next to your lock method. However, adding arbitrary text is not supported natively.

Example ADB Command (for reference):

bash
Copy
adb shell settings put secure lock_screen_owner_info "Your Text Here"

This command adds owner info text to the lock screen, but it is limited to a single line and may not appear on all devices or LineageOS versions.

Summary Table

If you want more advanced customization, consider using a custom lock screen app or exploring Xposed/EdXposed modules (if supported by your LineageOS version).
