If you're unhappy with a paid app, you can request a refund within 15 minutes of buying it. Your credit or debit card won't be charged and the application will be removed from your phone.
To get a refund:
- On the homescreen, tap Play Store. You can also access Play Store in Applications
- Tap Menu then My Apps
- Tap on the app you want to get refunded. The app will open
- Tap Uninstall. The app will now be uninstalled and the charge cancelled
- To confirm, tap OK
Note: You can download the same app again, but you won't be able to request another refund.
