I never needed this app to do anything related to my phone calls or dialer. I made a call after jnstaing it and it popped up. That's mildly annoying in itself but besides that, it took control over the dialing controls and would not allow me to use the keypad to respond to an auto attendant or to end the call. After this bad behavior the only way to end my call was to turn the phone off. I will immeduaty uninstall this terrible app.
