You will notice that the phonebook of your Android smartphone regroups contacts from different services (Google account etc) all together. You can configure Android to only display the contacts who's phone number you have, rather than by email, google account etc. In this article, we will show you how to configure this.

Note that: You can also create a custom contact list out of the different services your phone is connected to (Viber, WhatsApp, SIM contacts).
