Unlocking Delay with Fingerprint on AOD on Pixel 8 with Android 15 Beta 4

Users of the Google Pixel 8 running Android 15 Beta 4 are reporting a delay in fingerprint unlock functionality when using the Always-On Display (AOD). This issue manifests as a noticeable 3-4 second lag between pressing the fingerprint sensor and the device unlocking.

**Steps to Reproduce:**

1. Lock your Pixel 8.
2. While the phone is on the AOD, press the fingerprint sensor.
3. Wait for 3-4 seconds.
4. The device will eventually unlock.

This delay significantly impacts the user experience, as fingerprint unlock on AOD is expected to be a quick and seamless process.

**Possible Causes:**

The delay could be caused by several factors, including:

* Software bugs in Android 15 Beta 4: OS bugs may be interfering with the fingerprint sensor's responsiveness.
* Compatibility issues with installed apps: Certain apps, especially those involved in system security or device management, could be conflicting with the fingerprint unlock process.

* **System modifications:** The presence of modifications like Magisk and custom modules might be causing conflicts or instability.

**Troubleshooting Steps:**

While a definitive solution awaits an official fix from Google, users can try the following:

* **Update to the latest beta version:** Update your Pixel 8 to the newest available Android 15 Beta to ensure you have the latest bug fixes.
* **Disable potentially conflicting apps:** Identify and disable apps that might be interfering with the fingerprint sensor.
* **Reinstall problematic apps:** If you suspect a specific app is causing the issue, try reinstalling it.
* **Clear app caches and data:** Clearing the cache and data of apps related to fingerprint security and device management might help resolve conflicts.

**Note:**
These troubleshooting steps address common issues. If the problem persists, consider reaching out to Google's support forum or the developer community for further assistance. It's also recommended to back up your data before making any significant system changes.
