Root Call SMS Manager

This application allows users to block incoming calls and SMS messages on their Android devices. It also has the ability to support Dual SIM smartphones, meaning it can block calls and messages for each SIM card separately. This feature is available for Android 8 and above, and does not require root privileges. However, some program functions may require root access.

The blocking is done at the system level, so the program will not miss the first call and the screen will not light up when a call is blocked. This helps to avoid any distractions or interruptions from unwanted calls. The program also has the ability to replace the incoming call number, providing users with a private conversation option.

For calls, users can choose between two blocking options: "Reject" or "Not to answer". For SMS messages, users can set a filter in the text to block specific messages from a certain number. Multiple filters can be separated by a semicolon. Users can also create a list of numbers to block and make it current, or choose to not block any numbers at all.

The free version of the app has some limitations, such as only allowing two entries in the list and not supporting groups of contacts or exceptions. It also does not have a scheduler feature. However, users can integrate the app with Tasker by adding it as a task and choosing a list name to make it current. This allows for more customization and control over the blocking process.

In summary, this app provides users with the ability to block unwanted calls and messages on their Android devices. It has various features such as dual SIM support, private conversation options, and the ability to set filters and schedules. While some functions may require root access, the app can still be used without it.
