Hi @Jasmin91, let me see if I can help out here.
There is no pre-loaded feature in Xperia M4 Aqua enabling you to block numbers, however you can if you want to save the unwanted number as a contact and direct all calls from that number to voicemail. To do this, please follow the instructions below.
- Find and tap Contacts.
- Tap the contact that you want to forward to voicemail, then tap the Edit contact icon (icon with a contact and a pen).
- Tap the menu button (three vertical dots), then mark the All calls to voicemail checkbox.
- Tap Done / SAVE.
I hope that helped! Let me know if you have any further questions!
