Troubleshooting Hairline Curved Lines Below QQS on Pixel 8

This article helps users diagnose and potentially resolve a visual issue on the Google Pixel 8. Users report seeing small, hair-like curved lines appearing below the Quick Settings panel (QQS) when the Light QS Panel setting is enabled.

**Symptoms:** A thin, curved line resembling hair appears below the QQS, above the Notifications panel.

**Device Configuration:** This issue has been observed on Google Pixel 8 devices running Stock Android 15.0 with the December 2024 security patch and the latest Canary build.

**Possible Causes:**
* **Software Glitch:** This could be a temporary software bug or inconsistency.
* **Display Driver Issue:** A problem with the display driver might be causing the visual artifact.
* **Theme or Overlay Conflict:** A third-party theme or overlay might be interfering with the QQS layout.

**Troubleshooting Steps:**
1. **Reboot:** Restart your Pixel 8. This can often resolve minor software glitches.
2. **Disable Light QS Panel:** Toggle the Light QS Panel setting off and see if the lines disappear. This helps determine if the issue is directly related to the Light QS Panel.
3. **Update Pixel Buds:** If you are using Pixel Buds, ensure they are updated to the latest firmware.
4. **Update Apps:** Check for updates for any recently installed apps, as they might be involved.
5. **Clear Cache and Data:** Clear the cache and data for the System UI app. This can sometimes resolve display-related issues.

**Note:** Please refer to the Pixel 8 user manual or support documentation for specific instructions on clearing cache and data.

**Further Assistance:** If the problem persists, try creating a factory reset as a last resort. Before doing so, back up your important data. If issues continue after these steps, contact Google support for further assistance.
