    There’s no way to know that in react native till now, but on the other hand, you can check it using native java for android from here.

    boolean verifyInstallerId(Context context) {
    // A list with valid installers package name
    List<String> validInstallers = new ArrayList<>(Arrays.asList("com.android.vending", "com.google.android.feedback"));

    // The package name of the app that has installed your app
    final String installer = context.getPackageManager().getInstallerPackageName(context.getPackageName());

    // true if your app has been downloaded from Play Store 
    return installer != null && validInstallers.contains(installer);
}

    and here’s a native solution for IOS using native from this old answer here.

    I prefer you delete the storage for all users in your next update to solve the issue.

    And if you can specify the error you have maybe we can help on it.

    In this new version, you can do something like

    const savedVersion = await AsyncStorage.getItem('savedVersion'); // this will return null, because the previous version didn't set this value

const currentVersion = DeviceInfo.getVersion();

if (!savedVersion||semver.lt(savedVersion, currentVersion)) {
  await clearAllStorage();
  await AsyncStorage.setItem('savedVersion', currentVersion);
}
