Hello! I understand that in Beat Shooter on your Android device (WebKit, Android OS 15), the music and weapons are not loading after you launch the game. Let's try to get that fixed for you.

To clarify before we proceed:
- Is the game stuck on a loading screen, or does it load but the music and weapon sounds just don't play?
- Have you tried restarting the app or your device already?
- Are you connected to the internet when launching the game?

Meanwhile, here’s a step-by-step set of basic troubleshooting you can try:

1. Restart the Game and Device:
- Close Beat Shooter completely.
- Restart your Android device.
- Relaunch the game and check if music and weapons load.

2. Check Internet Connection:
- Beat Shooter may need a stable connection to download or verify music and weapon assets in the background.
- Make sure you have Wi-Fi or mobile data enabled and working.

3. Clear Cache:
- Go to your device’s Settings > Apps > Beat Shooter > Storage.
- Tap on “Clear Cache” (this does not delete your game progress).
- Restart the app and see if that helps.

4. Update the Game:
- Check the Google Play Store or the app source and ensure Beat Shooter is updated to the latest version.
- Sometimes bugs affecting music and assets are fixed in newer updates.

5. Reinstall the Game:
- If possible, back up your progress.
- Uninstall Beat Shooter, then reinstall it.
- This ensures corrupted files are replaced.

If none of these help, it might be a specific bug or compatibility issue on Android 15 or your device’s WebKit browser engine. In that case, let me know exactly what you see, and I can guide you with some advanced settings to try or help check if there is a known server-side issue.
