ConfigUpdater

ConfigUpdater is a system tool that is installed on all Android devices. This program automatically renews mobile device certificates, so you don't have to do it manually.
It should be noted that these certificates are important and are responsible for performing the functions of viewing content on the Internet. Each site has its own certificate, which guarantees that all information sent and received is encrypted using the secure TLS or SSL encryption protocol.
Your mobile device has its own certificates that allow you to use the Internet and view data on any website using the HTTPS protocol. If the certificates are not updated, then after a couple of years you will not be able to use the Internet.
In addition to working with websites, certificates are also required for working with other applications. They also use certificates to securely connect to company servers and to connect to the Internet.
It should be noted that ConfigUpdater also manages the phone's time zone and firewall. Basically, this tool is installed automatically, but there are situations when you accidentally deleted or reset the settings, and in such a situation you need to re-download the application.
