The logging system
Call Master can manipulate both internal and system logs for calls and text messages. By default, everything that is blocked will only be logged within Call Master. If you find numbers have been blocked by mistake blocked, you can long-press any item in the logs to export it to the system. Anything that is allowed will be automatically sent to the system.
In the near future we will implement a private call and messaging system that will export/delete and import/delete logs of both kinds without the need for our own dialer. This will save memory and processing power.
