@GamesOnAcid Generally you should not call any methods in OnApplicationQuit as objects are in the process of being unloaded from memory. I would recommend that you debug the game, either using Visual Studio or just placing Debug.Log statements around your db calls to capture the runtime variable values, they will show in the device logs via “adb logcat”. Also, please share the code you are using, we may be able to make recommendations. Tips for new Unity users and How To - Capturing Device Logs on Android
