Hi! I understand your Duke Energy app shows a white, blank screen when opened even after reinstalling and toggling airplane mode. Thanks for sharing what you've already tried. Let's try a few more things to get this sorted on your Android 10 device.

First, just to confirm:

1. Is your phone connected to the internet with a stable Wi-Fi or cellular connection when you open the app (not in airplane mode)?
2. When you reinstall, are you downloading the latest version of the Duke Energy app from the Google Play Store?
3. Does the app get stuck on the white screen immediately upon opening, or after a few seconds?
4. Have you checked if your device storage is low? Sometimes apps fail to load properly if storage is nearly full.

Assuming your internet connection is good and there's enough space, try these steps:

1. Clear the app cache and data:
- Go to Settings > Apps > Duke Energy app > Storage.
- Tap "Clear Cache" and then "Clear Data."
- Reopen the app to check if it loads properly.

2. Check app permissions:
- In the same App Info screen, tap Permissions.
- Make sure the app has necessary permissions like location, storage, etc., enabled.

3. Clear your phone’s system cache partition (this won't delete your personal data):
- Turn off your phone.
- Hold the Power and Volume Up buttons simultaneously until recovery mode appears.
- Use volume buttons to navigate to "Wipe Cache Partition" and select it with Power button.
- After it's done, reboot your phone.

4. Confirm your Android 10 system is fully updated:
- Settings > System > Software Update.

If none of these work, the issue might be related to a backend server or app bug. In that case, contacting Duke Energy's mobile app support via [email protected] might be best.

Would you like me to guide you through clearing cache and checking permissions now?
