Can't open iKeyMonitor app

FAQs
1

I typed app PIN, but when I pressed “call” button - iKeyMonitor app temporarily showed, but overlapped by the standard “call window”… after that iKeyMonitor app is closed (((
So, I can’t open iKeyMonitor neither for changing settings nor nor uninstalling

Hi
You may end the call by tapping on the notification - “Stop/End”. And then keep configuring iKeyMonitor.
