Hi! I understand that after signing in to your Kardia app on your Android 10 WebKit device, you’re just seeing a blank white screen. Let's get this fixed together.

To start off, could you tell me if you see this blank screen immediately after signing in or does it happen after some loading time? Also, have you tried closing the app fully and reopening it?

Meanwhile, here’s a step-by-step guide to troubleshoot the blank white screen issue:

1. Force close the app: Go to your recent apps, swipe the Kardia app away to close it completely.
2. Clear cache and app data:
- Go to Settings > Apps > Kardia app > Storage.
- Tap "Clear Cache" first. If the issue persists, then tap "Clear Data" (this will log you out, so you’ll need to sign in again).
3. Restart your phone: Rebooting can resolve temporary glitches.
4. Check for app updates: Open Google Play Store, search for Kardia, and update if available.
5. Ensure Bluetooth is enabled: Some versions require Bluetooth to connect properly even after signing in.
6. Reinstall the app: Uninstall the Kardia app and install it again from Google Play Store to refresh the configuration.

Since you’re using Android 10 on WebKit, compatibility should generally be good, but sometimes cache corruption causes blank screens. If you’ve already tried these steps, please let me know which ones, and I can guide you through more advanced checks.

Are you able to see the sign-in screen initially every time, or does the app just freeze on the white screen immediately?

Let me know!
