You know Android phone allow you to block contacts on your phone. The procedure can be unique on your Sony Xperia U. It varies from phone to phone.
Users of the Sony Xperia U can take advantage of the phone’s Reject List, which keeps a list of numbers that are blocked.
There are two ways to add a contact onto the Reject List. The easiest way is as follows:
1. Open your Sony Xperia U contact’s page.

3. Choose Add to Reject List.
The steps above will cause all of the selected contact’s numbers to be added to the Reject List. On the Contacts list, blocked numbers are shown with the blue universal “No” symbol.
If you need to block only some of the contact’s numbers, you can unblock the valid numbers through the Auto Reject List menu in the Sony Xperia U app.
The Sony Xperia U also has the Blocking Mode feature, which lets you limit phone calls at certain hours. To enable Blocking Mode, go to Settings. Open the My Device page, click the Blocking Mode option, and from there turn on the Blocking Mode switch. You can select what features to block. You can disable incoming calls, notifications, alarm and timer, and/or LED indicator.
When blocking calls in this way, all incoming calls will be automatically rejected and you will not hear any ring or feel any vibration when there is an incoming call, but you will see a notification of the missed call. If you want certain contacts to be able to reach you even if Blocking Mode is enabled, specify them in the list of Allowed Contacts.
