Has anyone encountered this issue on a Nexus 6P device? I am only getting this issue on a Nexus 6P (running Google Fi).

When I install the app there is a key for `userIsLoggedIn` inside `SharedPreferences`.

This block:

    boolean userIsLoggedIn  = SharedPrefs.userIsLoggedIn(this);

    // Then in another class...

     public static boolean userIsLoggedIn(Context context) {
        // For users updating apps, if the previous key-value is a string, convert it to boolean
        try {
            return context.getSharedPreferences(LOGIN_FILE, Context.MODE_PRIVATE)
                    .getBoolean(USER_LOGGED_IN, false);
        } catch (ClassCastException e) {
            Logger.e(TAG, e.getMessage());
            context.getSharedPreferences(LOGIN, Context.MODE_PRIVATE)
                    .edit()
                    .putBoolean(USER_LOGGED_IN, false)
                    .commit();
            return context.getSharedPreferences(LOGIN, Context.MODE_PRIVATE)
                    .getBoolean(USER_LOGGED_IN, false);
        }
    }

Now this should return `false` on a new uninstall but debugging this on a fresh install I get the following on App Startup.

I also running Proguard if that matters, when running the device on a non-proguard enabled APK it runs ok. Running proguard on any other devices runs fine.
