I started having problems with my new phone 1/16/21 after an update my phone started processing request for MCM client for everything I did from making a call to sending a text and I noticed that I would loose Tmobile network and would not be able to connect to wifi until a restart Then the issues would start back with loosing calls and text’s would not send. I uninstalled Carrier Hub and disabled automatic update for it then removed all permissions for MCM client and just like magic my phone is like new again with 0 problems.
