I got to know it was to be available for the purchase of Nine now, but I don't know how I have to do it.
You can purchase Nine from Google Play via in-app billing.
Please purchase as below procedures.
- Nine Settings > About > Purchase
- Nine Settings > Touch the purchase icon on the toolbar
If Google service is not installed on your device or want to purchase the volume license, you can purchase it with the link below via Paypal.
