On LineageOS 23.2, retrieving the text displayed on the lock screen via ADB is not straightforward because ADB does not have direct access to the lock screen's UI elements or their text content for security reasons. However, there are a few approaches you can try, depending on your device's state and permissions:

If the device is unlocked and USB debugging is authorized:

• You can use ADB to dump the current activity or window hierarchy, which might include the lock screen text. For example:

  bash
  Copy
  adb shell dumpsys window
  adb shell dumpsys activity

  These commands may reveal the text in the lock screen widgets or notifications, but not the lock screen PIN/pattern itself for security reasons.

If the device is locked:

• ADB commands generally cannot interact with or retrieve the lock screen PIN, pattern, or password directly. This is a security feature of Android and LineageOS.
• If you are trying to bypass the lock screen, you would typically need root access or a custom recovery (like TWRP) to remove lock screen files, but this is not recommended for security and data integrity reasonsandroid.stackexchange.com+1.

If you want to simulate input (e.g., to unlock the device):

• You can use ADB to send input events, such as:

  bash
  Copy
  adb shell input text YOUR_PIN
  adb shell input keyevent 66  # presses Enter

  This will only work if USB debugging is already authorized and the device is not fully locked outstackoverflow.com.

Important Notes:

• Security: Android and LineageOS are designed to prevent unauthorized access to lock screen credentials via ADB.
• Root Access: If your device is rooted, you may have more options, but this is risky and not recommended for most users.

If you clarify your goal (e.g., retrieving a specific notification text, bypassing the lock screen, or debugging), I can provide more targeted advice. What exactly are you trying to achieve?
