Hi there! I see that your SAKURA School Simulator app is crashing on your Kindle device running Android 9. I’d love to help you get that sorted. To start, could you tell me a bit more about when the crashes happen? For example, does it crash right when you open the app, or maybe when starting a new game, or during gameplay? Also, have you noticed any error messages or patterns?

In the meantime, here are some general troubleshooting steps tailored for your device and OS that often help with app crashes:

1. Restart your Kindle device – A quick reboot can clear temporary glitches.
2. Update the app – Ensure you have the latest version of SAKURA School Simulator installed from the Google Play Store, as updates often fix bugs causing crashes.
3. Clear the app cache and data:
- Go to Settings > Apps & notifications > See all apps > SAKURA School Simulator.
- Tap Storage & cache.
- Tap Clear cache first, then try opening the app.
- If it still crashes, you can try Clear storage/data but note this might erase your saved progress, so back up if possible.
4. Free up device storage – Low internal storage can cause apps to crash.
5. Reduce in-game settings – If the app crashes soon after starting, reducing the number of students and people in settings can improve performance and stability.

If after trying these steps the crashes continue, please let me know if you tried clearing data and if your game progress is important, so I can suggest safer alternatives or advanced fixes. Also, checking if the app’s server or account features are online can help if the crash relates to account syncing.

Does any of this sound like your situation? Let me know how it goes!
