Hi! Thanks for reaching out. I understand you're experiencing crashes when starting the Blue Wallet app on your Android device running version 16. To help get this sorted, could you tell me if this started happening recently, like after an app update or a system update? Also, have you noticed if it crashes immediately on launch or after some loading? Any extra details will help me guide you better.

In the meantime, here’s a straightforward step-by-step approach to try:

1. Restart your device: A simple reboot can clear temporary glitches.

2. Clear Blue Wallet cache:
- Go to your device’s Settings > Apps > Blue Wallet.
- Tap on Storage & cache.
- Select “Clear cache” (avoid “Clear data” for now, as that might remove your wallet data).

3. Check app permissions:
- Ensure Blue Wallet has the necessary permissions, especially for network access and storage.

4. Try disabling Wi-Fi for Blue Wallet temporarily:
- Some users have reported crashes on Android unless Wi-Fi is disabled for the app.
- You can do this via your device’s Settings > Apps > Blue Wallet > Network permissions; toggle off Wi-Fi access and try starting the app again.

5. Update or reinstall the app:
- Make sure you have the latest version from the Google Play Store.
- If already latest, try uninstalling and reinstalling the app.

If after these steps the app still crashes at startup, there might be a less common issue, potentially related to a bug with the app or compatibility with your Android version.

Have you tried any of these steps yet? If so, which ones? That way, I can suggest the next best actions for you.

Looking forward to your reply so we can get your Blue Wallet up and running smoothly!
