Hi there! I understand that your FreeStyle Libre 3 app is running slowly most of the time, and your meter with 4 days left is stuck on the same page. Let’s get this sorted out together.

To start, could you tell me if you have tried closing and reopening the app or restarting your phone? Sometimes this can refresh the app’s performance.

In the meantime, here are some step-by-step suggestions you can try on your Android 10 device to improve app speed and address the meter issue:

1. Force close and reopen the FreeStyle Libre 3 app: Go to your phone’s Settings > Apps > FreeStyle Libre 3 > Force Stop. Then reopen the app and check if it’s faster.

2. Clear app cache:
- Open Settings > Apps > FreeStyle Libre 3 > Storage.
- Tap on “Clear Cache” only. Avoid clearing data as it might erase settings.
- Relaunch the app afterward.

3. Check for app updates: Ensure that you have the latest version of the FreeStyle Libre 3 app from Google Play Store. Developers often fix performance issues in newer versions.

4. Restart your phone: A simple reboot can sometimes resolve temporary issues affecting app functionality.

5. Check internet connection: Though the app primarily communicates with the meter via Bluetooth, some features may require network access. Ensure your phone has a stable connection.

6. Meter stuck issue: For the meter display stuck on the same page with a sensor about to expire (4 days left),
- Try removing the sensor from the app and then re-adding or resyncing it by scanning again.
- Ensure the sensor is properly applied and the phone is close to the sensor during scans.

If you’ve already done any of these, please let me know which ones, and also if you see any error messages or specifics on the stuck meter screen. This will help me guide you better.

If the problem persists, we might explore reinstalling the app or checking account sync settings next.

How does that sound? Would you like to try these steps, or do share what you have tried so far!
