Hi there! I understand that your Facer app is not opening on your Android device. Let's try to get it working for you. To help me assist you better, could you please tell me if you see any error messages when you try to open the app, or does it just show a blank screen or crash right away?

Meanwhile, here are some initial steps we can try that usually help on Android 10 devices with WebKit browser environment:

1. Restart Your Device: Sometimes a simple restart of your phone clears temporary issues.

2. Check App Permissions: Facer needs certain permissions to function properly. Go to Settings > Apps > Facer > Permissions, and make sure all required permissions are granted.

3. Clear App Cache and Data:
- Go to Settings > Apps > Facer > Storage.
- Tap "Clear Cache" and then "Clear Data."
- Then try opening the app again.

4. Update the App: Check Google Play Store for any available updates to the Facer app and install them.

5. Reinstall the App: If issues persist, uninstall Facer and reinstall it fresh from the Play Store.

If you have already tried any of these, please let me know which ones so we can look deeper into the issue, possibly involving syncing or network connection checks.

Does the app attempt to open at all, or does it instantly close? Let me know!
