Since samsung has not implemented the PackageManager.getInstallerPackageName(), it still returns null. So use the PackageManager.getInstalledPackages() to get all the packages and search for the samsungapp packagename "com.sec.android.app.samsungapps".

Stores:

null - developer
com.android.vending - google play
com.amazon.venezia - amazon app
com.sec.android.app.samsungapps - samsung app store

Code:

// lets start with google play store link
String link = "https://play.google.com/store/apps/details?id=com.hellothupten.capital2countryquiz";

//find out the installer for your app package name.
String installer = getPackageManager().getInstallerPackageName(
        "com.hellothupten.capital2countryquiz");

if (installer == null) {
    List installedPackages = getPackageManager()
            .getInstalledPackages(PackageManager.GET_ACTIVITIES);
    for (PackageInfo p : installedPackages) {
        if (p.packageName.contains("samsungapps")) {
            // change to samsung app store link
            link = "http://apps.samsung.com/mars/topApps/topAppsDetail.as?productId=000000840239";
            break;
        }
    }
} else if (installer.contains("amazon")) {
    // change to amazon app store link
    link = "amzn://apps/android?p=com.hellothupten.capital2countryquiz";
} else if (installer.contains("samsung")) {
    // change to samsung app store link. This does not
    // exist..but who knows samsung may implement
    // getInstallerPackageName in future, I assume it will
    // contain a word samsung in its package name.
    link = "http://apps.samsung.com/mars/topApps/topAppsDetail.as?productId=000000840239";

}

Use the link variable as the store link.
