Hi! I’m Daniel Otega. I understand your Dexcom G7 app isn’t opening at all, so you can’t even see your glucose readings. Let’s see how we can get that fixed for you.

To start, could you share if you’re seeing any error messages when trying to open the app? Also, have you recently updated the app or your Android OS, or made any changes to your phone settings? This info will help me guide you better.

Meanwhile, here are a few steps we can try, tailored for your Android 10 device and WebKit browser environment:

1. Restart your Device: Sometimes a simple restart refreshes background processes that might cause the app to hang.

2. Close Background Apps: Ensure no other apps are interfering by closing all running apps, then try opening the Dexcom G7 app again.

3. Clear App Cache and Data:
- Go to Settings > Apps > Dexcom G7
- Tap on Storage
- Clear Cache first, then if needed, Clear Data (Note: Clearing Data may require logging back into the app.)

4. Check Bluetooth: Dexcom G7 relies on Bluetooth to connect to the sensor. Disable Bluetooth, wait 10 seconds, then turn it back on and try the app again.

5. Update the App: Make sure your Dexcom G7 app is updated to the latest version available in the Google Play Store.

6. Reinstall the App: If the app still won’t open, uninstall it, then reinstall from the Play Store. This can fix corrupted files.

7. Network Connectivity: Ensure you have a stable internet connection since the app syncs data online.

If after these steps, your app still won’t open, we might want to check for any server outages or account-related issues. I can guide you through advanced troubleshooting or help you reach Dexcom support if necessary.

Let me know how these steps go or if you observe any particular behavior with the app. I’m here to help!
