Started after update 4.5.30. People start to complain that they cannot understand anymore what I am saying. The words are being chopped. This happend already with earlier releases of MIUI, but occured mainly while talking with bluetooth. This is not just a bug, this phone (mi3w) cannot be used for phonecalls. I can't imagine I am the only one that is confronted with this malfunctioning. Updates are loaded using the standard updater. Typically this occurs after a certain period of time. It may occure immediately, but it may also occur after 5-15 minutes while in the call.
