Call & Text Filter lets you block unwanted calls and texts, for example, calls from telemarketers. The app filters calls and text messages (SMS) using lists of allowed and blocked contacts and in accordance with the selected filter rule.
You can select one of the following filter rules:
Filtering is off. The app does not filter calls and texts.
Blocked contacts. The app blocks calls and texts from the phone numbers in the list of blocked contacts (set by default). Your number will appear busy to blocked contacts. The app deletes blocked text messages and stores information about them in a report.
Allowed contacts. The app allows calls and texts only from the list of allowed contacts. Other calls and texts are blocked. The app deletes blocked text messages and stores information about them in a report.
Standard filtering. The app blocks and allows calls and texts using the lists of blocked and allowed contacts. If a call or text message is received from a number that is not in either of the lists, the app delivers it and prompts you to add the phone number to either the blocked contact list or the allowed contact list.
Limitations on hiding text messages (SMS)
Due to the technical limitations in Android 4.4 and newer, Call & Text Filter may not block messages from blocked contacts in some messaging apps.
